DEPOSIT FLIGHT PREVENTION: LEGAL INSTRUMENTS UNDER SPANISH BANKING LAW, INDIAN BANKING LAW AND INTERNATIONAL REGULATORY STANDARDS

ABSTRACT

Deposit flight prevention is an important component of modern banking regulation, financial stability and depositor protection. It refers to the legal, supervisory, prudential and institutional mechanisms designed to reduce the risk of sudden and widespread withdrawals of bank deposits that may threaten a credit institution’s liquidity, solvency or continued operation. Deposit flight may arise from actual financial weakness, rumours, loss of public confidence, digital bank runs, economic crises or contagion from the failure of another financial institution.

Spain addresses this risk through a combination of national banking legislation, European Union prudential requirements, deposit guarantee arrangements, supervisory intervention and bank recovery and resolution mechanisms. India employs a different institutional structure based on the Reserve Bank of India, statutory liquidity requirements, deposit insurance, corrective supervision, restrictions on withdrawals in specified circumstances and statutory resolution or reconstruction arrangements.

Internationally, the Basel Committee on Banking Supervision, the Financial Stability Board, the International Monetary Fund and the European Union have developed standards intended to improve liquidity resilience, maintain confidence in banking systems and facilitate the orderly management of failing institutions.

This paper examines the principal legal instruments relevant to deposit flight prevention in Spain, compares them with Indian banking law, analyses seven judicial decisions concerning banking resolution and financial stability, and evaluates the role of international standards. It argues that deposit flight cannot be prevented through a single legal instrument. Effective prevention requires a combination of liquidity regulation, credible deposit protection, transparent communication, early supervisory intervention, emergency liquidity arrangements and orderly bank resolution.

1. INTRODUCTION

1.1 Meaning of deposit flight

Deposit flight occurs when a substantial number of depositors withdraw their money from a bank within a relatively short period. It can affect an individual institution or spread across several institutions, producing systemic instability.

Banks generally accept deposits that may be repayable on demand or at relatively short notice and use a significant proportion of their funding to support loans and other assets with longer maturities. This maturity transformation is fundamental to banking, but it exposes banks to liquidity risk.

A bank may hold assets whose long-term value exceeds its liabilities and nevertheless experience a liquidity crisis if it cannot obtain sufficient cash to satisfy immediate withdrawal demands. A rapid loss of deposits can force the bank to sell assets at distressed prices, incur substantial funding costs or seek emergency liquidity assistance.

Deposit flight can therefore arise from two distinct but related problems:

1. Liquidity stress: The bank cannot obtain cash quickly enough to meet its payment and withdrawal obligations.
2. Solvency concerns: Depositors fear that the bank’s assets are insufficient to cover its liabilities or that it may eventually fail.

A liquidity crisis can develop even when a bank is not initially insolvent. Conversely, a bank with serious solvency problems may experience accelerated deposit withdrawals as confidence deteriorates.

1.2 Meaning of deposit flight prevention

Deposit flight prevention encompasses legal and regulatory measures intended to reduce the likelihood, speed, severity and systemic consequences of mass withdrawals.

Its principal objectives are:

• Maintaining public confidence in the banking system.
• Ensuring that banks possess adequate liquid assets and stable funding.
• Protecting eligible depositors if a bank fails.
• Detecting and addressing liquidity weaknesses before they become critical.
• Preventing the failure of one institution from triggering widespread contagion.
• Ensuring the continuity of essential banking and payment services.
• Establishing lawful procedures for intervention, resolution and compensation.

Deposit flight prevention must not be confused with a general prohibition on depositors withdrawing their money. In an ordinary banking relationship, customers retain contractual and statutory rights to access their deposits, subject to applicable law, contractual arrangements and lawful restrictions.

The purpose of regulation is primarily to make banks sufficiently resilient to meet legitimate withdrawals and to manage failures in an orderly manner. It is not to eliminate depositor freedom or to conceal genuine financial weakness.

1.3 Legal significance

Deposit flight prevention occupies an important position at the intersection of banking law, administrative law, contract law, insolvency law and financial regulation.

A bank's contractual obligation to repay deposits must be balanced against the need to preserve the stability of the wider financial system. Regulators may impose liquidity requirements, require corrective measures, restrict certain activities or initiate resolution proceedings where statutory conditions are met.

Nevertheless, emergency intervention must have a legal basis, pursue a legitimate public objective and comply with applicable procedural and substantive safeguards.

The Spanish and Indian systems provide useful comparative examples of how different legal frameworks address these competing objectives.

2. LEGAL FRAMEWORK GOVERNING DEPOSIT FLIGHT PREVENTION IN SPAIN

2.1 Constitutional and institutional background

Spain is a member of the European Union and participates in the European Banking Union. Consequently, Spanish banking regulation consists of national legislation together with directly applicable European Union regulations, European directives implemented into Spanish law and supervisory requirements adopted by competent authorities.

The principal institutions include:

• Banco de España: The national central bank and an important banking supervisory authority, particularly for institutions that are not directly supervised by the European Central Bank.
• European Central Bank (ECB): Exercises significant prudential supervisory responsibilities over significant credit institutions under the Single Supervisory Mechanism.
• Single Resolution Board (SRB): Responsible for specified bank-resolution functions under the Single Resolution Mechanism.
• Fondo de Reestructuración Ordenada Bancaria (FROB): Spain's national resolution authority, responsible for relevant resolution functions under Spanish and European law.
• Fondo de Garantía de Depósitos de Entidades de Crédito (FGD): Spain's deposit guarantee scheme, which protects eligible deposits within the applicable statutory framework.

These institutions perform complementary functions. Prudential supervision seeks to reduce the probability of bank failure, deposit insurance protects eligible depositors against specified losses, and resolution authorities manage the failure of institutions when preventive measures are insufficient.

2.2 Law 10/2014 of 26 June on the regulation, supervision and solvency of credit institutions

Law 10/2014, known as the Law on the Regulation, Supervision and Solvency of Credit Institutions, is one of the central components of Spanish banking legislation.

The law establishes the national framework for regulating and supervising credit institutions, including authorisation, governance, prudential requirements, supervisory powers and sanctions.

Its relevance to deposit flight prevention lies in its contribution to the safety and soundness of banks.

The legislation supports a supervisory framework under which institutions must maintain appropriate governance structures, identify material risks and comply with applicable prudential requirements. Supervisors can use their statutory powers to address deficiencies before those deficiencies develop into a threat to depositors or financial stability.

The law must be read together with Royal Decree 84/2015, which implements it, and the relevant European Union prudential framework.

Legal significance: Law 10/2014 does not establish a universal prohibition on deposit withdrawals. Instead, it contributes to preventing the conditions that may cause deposit flight by regulating the institutions that accept deposits and empowering supervisors to address weaknesses.

2.3 Royal Decree 84/2015 of 13 February

Royal Decree 84/2015 implements Law 10/2014 and provides further detail concerning the regulation and supervision of Spanish credit institutions.

It forms part of the national framework governing the authorisation, organisation, governance and prudential supervision of banks.

Its contribution to deposit flight prevention is indirect but substantial. Effective supervision and appropriate governance help ensure that banks identify financial vulnerabilities, maintain adequate controls and respond to developing risks.

The decree operates alongside European prudential legislation and Banco de España's implementing supervisory requirements.

2.4 Regulation (EU) No 575/2013: Capital Requirements Regulation

Regulation (EU) No 575/2013, commonly known as the Capital Requirements Regulation or CRR, establishes prudential requirements for credit institutions and certain investment firms.

It addresses capital adequacy, risk exposure, reporting and liquidity-related requirements, subject to subsequent amendments and the applicable consolidated legislative framework.

Capital and liquidity are related but distinct.

Capital provides a buffer against losses. Liquidity enables a bank to meet payments as they fall due. A bank with strong capital can still experience severe liquidity stress if it cannot convert assets into cash quickly enough.

The CRR therefore contributes to deposit flight prevention by strengthening the prudential position of institutions and establishing requirements designed to improve resilience.

The regulation must be read together with subsequent European Union legislation, including the relevant amendments to the CRR and the Capital Requirements Directive framework.

2.5 Liquidity Coverage Ratio and Net Stable Funding Ratio

Two particularly important prudential instruments are the Liquidity Coverage Ratio (LCR) and the Net Stable Funding Ratio (NSFR).

The LCR is intended to ensure that a bank maintains an adequate stock of high-quality liquid assets capable of covering its projected net cash outflows during a prescribed short-term stress period, ordinarily 30 calendar days.

Its purpose is to ensure that a bank can withstand a significant short-term liquidity shock without immediately resorting to extraordinary measures.

The NSFR promotes a more stable funding structure over a longer horizon. It compares available stable funding with the amount of stable funding required by the institution's assets and activities.

These requirements address different aspects of liquidity risk:

• The LCR focuses on short-term resilience under stressed conditions.
• The NSFR focuses on structural funding stability.
• Together, they discourage excessive reliance on unstable short-term funding and improve the capacity to withstand deposit withdrawals.

These ratios are prudential requirements, not guarantees that a bank can survive every conceivable withdrawal event. Their effectiveness depends on the quality of risk management, the accuracy of assumptions about depositor behaviour and the institution's ability to mobilise liquid assets during actual stress.

2.6 Banco de España Circular 2/2016

Banco de España Circular 2/2016 of 2 February 2016, together with subsequent amendments, contributes to the implementation of the European prudential framework in Spain.

It addresses matters concerning the supervision and solvency of credit institutions and supplements the applicable regulatory framework.

In relation to deposit flight prevention, liquidity-risk governance, reporting, internal controls and supervisory assessment are particularly important.

Banks need systems capable of monitoring deposit concentrations, funding maturities, cash-flow projections, collateral availability and potential outflows under stress.

Effective supervisory review can identify weaknesses in these systems and require appropriate remedial action.

The circular must be applied in its currently effective, consolidated form and alongside directly applicable European Union requirements.

2.7 Law 11/2015 of 18 June on the recovery and resolution of credit institutions and investment firms

Law 11/2015 is a central instrument governing bank recovery and resolution in Spain. It transposed the European Union's Bank Recovery and Resolution Directive framework into Spanish law.

It establishes arrangements for preparing for financial distress, intervening in failing institutions and resolving institutions where statutory conditions are satisfied.

The legislation is particularly relevant where deposit flight has become part of a broader institutional crisis.

Its principal contributions include:

1. Recovery planning and preparatory measures.
2. Resolution planning and assessment of resolvability.
3. Early intervention and supervisory coordination.
4. Use of statutory resolution tools.
5. Protection of financial stability and continuity of critical functions.
6. Protection of eligible depositors and client assets.
7. Allocation of losses in accordance with the applicable creditor hierarchy and statutory safeguards.

Resolution tools may include the sale of business, the transfer of assets or liabilities to an appropriate vehicle, and the write-down or conversion of eligible liabilities through bail-in, subject to applicable law.

Bail-in is not equivalent to confiscation of every customer's deposit. The treatment of liabilities depends on their legal classification, the applicable depositor-protection rules and the specific resolution measure.

Eligible covered deposits receive special protection under the relevant framework. Other liabilities may be subject to different treatment.

The objective is to preserve critical banking functions and avoid disorderly failure, rather than automatically rescue shareholders or protect every investor from loss.

2.8 Royal Decree 2606/1996 and the Spanish Deposit Guarantee Fund

Royal Decree 2606/1996 of 20 December historically established important rules concerning the Deposit Guarantee Fund for Credit Institutions. It has been amended, including in connection with the implementation of the European deposit guarantee framework.

Spain's deposit guarantee arrangements must be read together with Directive 2014/49/EU on deposit guarantee schemes and the currently applicable national provisions.

The standard protection limit under the European framework is generally EUR 100,000 per depositor per credit institution, subject to the applicable rules on eligible deposits, aggregation of accounts, exclusions and temporary high balances.

This means that separate accounts held by the same depositor at the same bank are ordinarily aggregated for the purpose of applying the standard limit. Accounts at different banking institutions are assessed separately, subject to the applicable legal rules.

Certain temporary high balances receive additional protection under specified conditions and for limited periods.

Deposit insurance contributes to deposit flight prevention because it reduces the financial incentive for eligible depositors to withdraw funds merely out of fear that a bank may fail.

However, deposit insurance does not guarantee that a bank will never experience a run. It protects eligible depositors against specified losses if the legal conditions for compensation are met.

2.9 European Union deposit guarantee and resolution framework

Directive 2014/49/EU establishes the framework for deposit guarantee schemes across participating European Union states.

Directive 2014/59/EU, known as the Bank Recovery and Resolution Directive (BRRD), establishes a framework for recovery and resolution of credit institutions and investment firms.

Regulation (EU) No 806/2014 establishes the Single Resolution Mechanism for participating institutions within the Banking Union.

These instruments perform related but different functions.

The deposit guarantee framework seeks to protect eligible depositors and strengthen confidence. The BRRD provides national recovery and resolution rules. The Single Resolution Mechanism establishes centralised resolution arrangements for institutions within its scope.

When a bank becomes failing or likely to fail, resolution authorities must consider the statutory conditions for intervention, including whether alternative measures could prevent failure within a reasonable timeframe and whether resolution is necessary in the public interest.

The Spanish resolution of Banco Popular Español in June 2017 illustrates how these instruments may be used during acute liquidity stress. The bank was resolved through a sale-of-business approach, with the objective of preserving critical functions and protecting financial stability.

The event demonstrates that deposit flight prevention is not limited to stopping withdrawals before a crisis. It also involves having a credible legal mechanism for maintaining essential banking services if preventive measures fail.

2.10 Law 10/2014 and the distinction between lawful restrictions and deposit flight prevention

Spanish law recognises that banks are subject to anti-money-laundering, customer-identification and other legal obligations that may require restrictions on specific accounts.

Under the applicable anti-money-laundering framework, including Law 10/2010 of 28 April on the prevention of money laundering and terrorist financing, banks may need to obtain customer information, conduct due diligence and comply with lawful freezing or restriction obligations.

These restrictions are distinct from a general measure intended to prevent deposit flight.

A bank should not arbitrarily prevent ordinary withdrawals merely because it wishes to retain its funding. Equally, a bank may be required by law to restrict transactions where a relevant statutory obligation applies.

The legal basis, purpose, proportionality and procedural requirements of any restriction must therefore be examined separately.

3. PRINCIPAL LEGAL INSTRUMENTS FOR DEPOSIT FLIGHT PREVENTION IN SPAIN

The principal instruments can be classified according to their functions.

First, preventive prudential regulation. Law 10/2014, Royal Decree 84/2015, the CRR, applicable liquidity rules and Banco de España supervisory requirements seek to reduce the probability that an institution will experience destabilising liquidity stress.

Second, supervisory intervention. Banco de España and the ECB, within their respective responsibilities, monitor institutions and may take appropriate supervisory action where legal conditions are met.

Third, depositor protection. The Spanish Deposit Guarantee Fund and the European deposit guarantee framework reduce the risk that eligible depositors will suffer losses solely because an institution fails.

Fourth, recovery and resolution. Law 11/2015, the BRRD and the Single Resolution Mechanism provide procedures for dealing with institutions that cannot be restored through ordinary supervisory or private-sector measures.

Fifth, financial stability coordination. The ECB, Banco de España, FROB and the SRB perform different functions in supervision, liquidity support and resolution. Their coordination is important because a liquidity crisis may escalate rapidly and cross national boundaries.

These instruments operate as a system. No single statute, liquidity ratio or deposit guarantee can independently eliminate all risks associated with deposit flight.

4. INDIAN BANKING LAW: DEPOSIT FLIGHT PREVENTION AND DEPOSITOR PROTECTION

4.1 Overview

India employs a statutory banking framework centred on the Reserve Bank of India (RBI), the Banking Regulation Act, 1949, the Reserve Bank of India Act, 1934, the Deposit Insurance and Credit Guarantee Corporation Act, 1961, and other applicable legislation.

Indian law addresses the risk of deposit flight through prudential requirements, liquidity regulation, supervision, corrective intervention, deposit insurance and statutory arrangements for dealing with distressed banks.

The Indian framework differs institutionally from Spain's European Banking Union model. Nevertheless, both systems seek to maintain public confidence, protect eligible depositors and prevent disorderly bank failure.

4.2 Banking Regulation Act, 1949

The Banking Regulation Act, 1949 is one of the principal statutes governing banking companies in India.

It regulates the conduct of banking business, including licensing, management, capital and reserves, inspection, directions and restrictions on certain activities.

The Act is significant for deposit flight prevention because it provides a legal framework for regulatory supervision and intervention.

Section 35 empowers the RBI to inspect banking companies in accordance with the statutory framework. Section 35A authorises the RBI to issue directions in the public interest, in the interest of banking policy, to prevent the affairs of a banking company from being conducted in a manner detrimental to depositors or prejudicial to the interests of the banking company, and to secure proper management.

Section 36 and other provisions also contribute to the RBI's supervisory and regulatory powers, subject to their specific statutory conditions.

Section 45 provides a framework for the imposition of a moratorium and related reconstruction or amalgamation arrangements in the circumstances prescribed by law. The precise procedure depends on the statutory provision and the applicable circumstances.

These powers are important where a bank's financial position threatens depositors or the stability of banking operations.

However, intervention must remain within the limits of the statute. The existence of supervisory powers does not mean that the RBI may impose any restriction it considers convenient without legal authority.

4.3 Reserve Bank of India Act, 1934

The Reserve Bank of India Act, 1934 establishes the RBI and provides its principal statutory framework.

The RBI performs central banking functions, including monetary policy, currency management and relevant financial-system functions. Its regulatory and supervisory responsibilities also derive from the Banking Regulation Act and other legislation.

In the context of deposit flight, the RBI's institutional role is important because it can assess banking-system liquidity, monitor financial conditions and use its lawful instruments to support monetary and financial stability.

The RBI's ability to provide liquidity to eligible institutions, subject to applicable conditions, may help address temporary funding pressures.

Emergency liquidity support is not equivalent to a guarantee that every bank will be rescued. It depends on the relevant legal authority, the nature of the institution's difficulties, available collateral, applicable conditions and the RBI's assessment.

4.4 Cash Reserve Ratio and Statutory Liquidity Ratio

The Cash Reserve Ratio (CRR) and Statutory Liquidity Ratio (SLR) are important prudential instruments in India.

The CRR requires banks to maintain prescribed cash reserves with the RBI in accordance with the applicable statutory and regulatory framework.

The SLR requires banks to maintain a prescribed proportion of their relevant net demand and time liabilities in specified liquid assets, subject to applicable rules.

These requirements serve different functions from the LCR and NSFR used in the European prudential framework.

CRR and SLR contribute to liquidity management and banking-system resilience, but they do not alone establish that a bank can withstand every possible episode of mass withdrawals.

Deposit flight prevention also requires bank-specific liquidity risk management, cash-flow forecasting, funding diversification and credible contingency funding plans.

4.5 RBI liquidity risk management requirements

Indian banks are subject to applicable RBI prudential directions and liquidity risk management requirements. The precise requirements depend on the type of institution and the relevant regulatory framework.

These requirements may address liquidity coverage, stable funding, stress testing, liquidity risk governance, contingency planning and reporting.

The LCR framework requires covered institutions to maintain an appropriate stock of high-quality liquid assets relative to projected net cash outflows under a prescribed stress scenario.

The NSFR framework, where applicable, promotes a more stable funding structure over a longer horizon.

Liquidity stress testing is particularly important because depositors do not always behave according to ordinary historical patterns. During periods of uncertainty, large depositors may withdraw funds quickly, and digitally enabled transfers may accelerate the process.

Banks therefore need to model different scenarios, including the loss of confidence among major depositors, deterioration in wholesale funding, collateral constraints and disruption in payment markets.

4.6 Deposit Insurance and Credit Guarantee Corporation Act, 1961

The Deposit Insurance and Credit Guarantee Corporation Act, 1961 establishes the statutory framework for deposit insurance in India.

The Deposit Insurance and Credit Guarantee Corporation (DICGC) provides deposit insurance for eligible deposits held with insured banks, subject to the governing legislation and applicable rules.

The standard maximum insurance limit is INR 5,00,000 per depositor per bank, inclusive of principal and interest, subject to the applicable aggregation rules and exclusions.

Deposits maintained by the same depositor in the same right and capacity with the same bank are generally aggregated for the purpose of applying the insurance limit. Separate branches of the same bank do not ordinarily provide separate insurance limits.

Deposit insurance is significant because it reduces the potential loss faced by eligible depositors if an insured bank fails.

It also contributes to confidence in the banking system by making depositor protection dependent on a statutory mechanism rather than solely on the financial condition of the individual institution.

Nevertheless, deposit insurance does not mean that every account holder can immediately withdraw all funds during every banking crisis. Access to funds during a moratorium, reconstruction or resolution process depends on the applicable legal arrangements.

4.7 RBI directions and restrictions on withdrawals

The RBI may impose legally authorised restrictions on banking operations in circumstances involving financial distress or other statutory grounds.

For example, restrictions may be imposed on withdrawals or certain transactions while a bank undergoes a moratorium or another form of regulatory intervention.

Such measures may be intended to preserve assets, prevent disorderly depletion of funds, facilitate reconstruction and protect the interests of depositors collectively.

However, withdrawal restrictions can create serious hardship for account holders and businesses. Their justification must therefore be assessed against the statutory basis, the seriousness of the bank's condition, the protection of depositors and the need to minimise disruption.

The existence of a banking crisis does not automatically authorise every possible restriction. The relevant legal power and procedural conditions must be satisfied.

4.8 Prompt Corrective Action framework

The RBI's Prompt Corrective Action (PCA) framework provides a supervisory mechanism for addressing specified weaknesses in covered banks.

Depending on the applicable framework and the indicators that trigger intervention, the RBI may impose restrictions or require corrective measures concerning matters such as capital, asset quality, profitability, leverage or other prescribed indicators.

PCA is relevant to deposit flight prevention because a bank's weaknesses may become more difficult to address if they are left unresolved until depositors lose confidence.

Early corrective intervention can reduce the likelihood that financial deterioration will progress into a severe liquidity or solvency crisis.

PCA should not be described as a complete deposit insurance mechanism or as an automatic prohibition on deposit withdrawals. It is a supervisory intervention framework designed to address specified vulnerabilities.

4.9 Insolvency, reconstruction and resolution of distressed banks

India's treatment of a distressed bank depends on its legal classification and the applicable statutory regime.

Banking companies are subject to specialised banking legislation, including the Banking Regulation Act. Cooperative banks may also be governed by additional provisions applicable to their institutional form.

It is therefore necessary to distinguish the insolvency framework applicable to ordinary companies from the special statutory arrangements governing banks.

The Insolvency and Bankruptcy Code, 2016 should not be treated as a universal, standalone bank-resolution statute that automatically governs all bank failures in the same manner as ordinary corporate insolvency.

Indian banking law relies significantly on regulatory intervention, statutory restrictions, reconstruction and amalgamation arrangements, and deposit insurance.

A coherent deposit flight prevention policy requires clear procedures for dealing with failing institutions, protecting eligible depositors and maintaining continuity of essential banking services.

5. COMPARATIVE ANALYSIS: SPAIN AND INDIA

5.1 Institutional structure

Spain operates within the European Banking Union, which combines national supervision and resolution arrangements with European Union institutions.

India relies primarily on the RBI for central banking, prudential regulation and supervision, with DICGC providing statutory deposit insurance.

Both systems combine preventive regulation with mechanisms for managing bank distress, but their institutional responsibilities and resolution arrangements differ.

5.2 Deposit insurance

Spain generally applies the European standard protection limit of EUR 100,000 per depositor per credit institution, subject to the applicable rules.

India generally applies an insurance limit of INR 5,00,000 per depositor per insured bank, inclusive of principal and interest and subject to statutory conditions.

These figures cannot be compared directly without considering exchange rates, income levels, the structure of banking markets, eligible deposits and the operation of the respective guarantee schemes.

In both systems, deposit insurance can reduce panic-driven withdrawals by giving eligible depositors greater certainty about the treatment of their funds if a bank fails.

5.3 Liquidity requirements

Spain applies the European prudential framework, including the CRR and applicable liquidity requirements.

India applies RBI-prescribed liquidity requirements, including the relevant CRR, SLR, LCR and NSFR frameworks according to the type of institution and applicable rules.

Both systems seek to improve liquidity resilience, but their legal instruments and supervisory implementation are not identical.

5.4 Supervisory intervention

Spanish banking supervision involves Banco de España and the ECB, depending on the institution and the relevant allocation of supervisory responsibilities.

In India, the RBI plays the central role in banking supervision and can exercise statutory powers under the applicable banking legislation.

Both jurisdictions recognise the importance of intervention before a bank's financial deterioration becomes irreversible.

5.5 Resolution and continuity of services

Spain's framework includes Law 11/2015, the BRRD and the Single Resolution Mechanism.

India relies on its banking-specific statutory and regulatory arrangements, including intervention, moratorium, reconstruction and amalgamation provisions where applicable.

Spain's experience demonstrates the importance of a structured resolution framework capable of maintaining critical banking functions during an acute crisis.

India's framework demonstrates the significance of centralised supervisory authority, statutory deposit insurance and intervention powers. However, the effectiveness of either system depends on implementation, the credibility of public communication and the capacity to act promptly.

6. SEVEN RELEVANT JUDICIAL DECISIONS

The following seven decisions concern bank resolution, financial stability, supervisory powers, procedural safeguards or the legal treatment of affected investors. They are particularly relevant to understanding the legal environment in which deposit flight is managed.

Important qualification: These decisions do not constitute seven cases establishing a standalone legal doctrine called “deposit flight prevention.” Most arise from the Banco Popular resolution in Spain and the European Banking Union framework. They are relevant because they clarify the legality, objectives and limits of the measures used to address bank failure and preserve financial stability.

CASE 1: AERIS INVEST SÀRL v COMMISSION AND SINGLE RESOLUTION BOARD

Citation: Case T-628/17, General Court of the European Union, judgment of 1 June 2022.

Facts: Aeris Invest challenged the resolution of Banco Popular Español in June 2017. The resolution involved the application of European Union resolution legislation and the transfer of the bank's business through the sale-of-business tool.

Legal issues: The proceedings concerned the legality of the resolution scheme, the allocation of powers among European Union institutions, the right to property, procedural rights and the duty to provide reasons.

Decision: The General Court dismissed the action challenging the resolution scheme.

Legal principle: The Court accepted that the resolution framework could be used to protect financial stability and preserve critical banking functions, provided that the statutory conditions were satisfied.

Relevance to deposit flight prevention: Banco Popular was experiencing acute liquidity stress. The resolution process was designed to avoid disorderly failure and preserve essential functions, including deposit-taking and payment services. The case demonstrates that financial stability may justify rapid administrative action where a bank satisfies the legal conditions for resolution.

It also illustrates that emergency intervention does not eliminate judicial review. Resolution authorities must operate within their statutory powers and comply with applicable legal requirements.

CASE 2: FUNDACIÓN TATIANA PÉREZ DE GUZMÁN EL BUENO AND SFL v SINGLE RESOLUTION BOARD

Citation: Case T-481/17, General Court of the European Union, judgment of 1 June 2022.

Facts: The applicants challenged the European Union resolution measures adopted in respect of Banco Popular.

Legal issues: The proceedings concerned the validity of the resolution scheme, the powers of the resolution authorities and the legal safeguards applicable to affected investors.

Decision: The General Court dismissed the action challenging the resolution measures.

Legal principle: The European Union resolution framework permits intervention in a failing bank where the prescribed conditions are met and the measure is justified by the applicable resolution objectives.

Relevance to deposit flight prevention: A resolution system can reduce the risk that the failure of one institution will destabilise other institutions or interrupt critical banking services. This decision forms part of the judicial examination of how that system operates during a crisis.

The case should not be interpreted as establishing that depositors' rights may be disregarded whenever authorities invoke financial stability. The applicable statutory protections and creditor hierarchy remain important.

CASE 3: DEL VALLE RUIZ AND OTHERS v COMMISSION AND SINGLE RESOLUTION BOARD

Citation: Case T-510/17, General Court of the European Union, judgment of 1 June 2022.

Facts: The applicants challenged aspects of the Banco Popular resolution, including the measures affecting investors and the decisions adopted by the European Union authorities.

Legal issues: The dispute concerned the legality of the resolution decision and the safeguards applicable to persons whose financial interests were affected.

Decision: The General Court dismissed the challenge to the resolution measures.

Legal principle: Bank resolution involves a balance between individual property interests and the public interest in maintaining financial stability, subject to the governing legislation.

Relevance to deposit flight prevention: A credible resolution framework helps ensure that bank distress can be managed without automatically interrupting the bank's essential functions. The decision illustrates the importance of maintaining a legally structured response to failure.

The case also demonstrates that shareholders and creditors may be affected differently from covered depositors. The legal treatment of each category depends on the relevant rules and the nature of the liability.

CASE 4: ELEVETÉ INVEST GROUP AND OTHERS v COMMISSION AND SINGLE RESOLUTION BOARD

Citation: Case T-523/17, General Court of the European Union, judgment of 1 June 2022.

Facts: The applicants challenged the Banco Popular resolution scheme and associated decisions.

Legal issues: The proceedings involved questions concerning the powers of the Single Resolution Board, the legality of the resolution process and the interests of investors affected by the intervention.

Decision: The General Court dismissed the challenge.

Legal principle: Resolution authorities may use the statutory resolution tools where the conditions for intervention are satisfied, while remaining subject to the legal framework governing their powers and obligations.

Relevance to deposit flight prevention: This case supports the broader proposition that deposit flight risk must be addressed within a structured resolution framework. Such a framework can preserve critical functions and reduce the consequences of disorderly failure.

It also highlights the distinction between protecting the banking system and guaranteeing the investment value of shareholders' holdings or other financial instruments.

CASE 5: ALGEBRIS (UK) LTD AND ANCHORAGE CAPITAL GROUP LLC v SINGLE RESOLUTION BOARD

Citation: Case C-934/19 P, Court of Justice of the European Union, judgment of 21 December 2021.

Facts: The applicants held or managed funds holding Additional Tier 1 and Tier 2 financial instruments associated with Banco Popular. They challenged the treatment of those instruments in the resolution process, including issues relating to valuation.

Legal issues: The proceedings concerned the interpretation of Article 20 of Regulation (EU) No 806/2014, particularly the requirements concerning definitive valuation and the consequences of the resolution measures.

Decision: The Court of Justice dismissed the appeal.

Legal principle: The consequences of the statutory valuation framework depend on the applicable provisions and the particular resolution tool employed. A resolution does not automatically entitle affected investors to every form of compensation they might seek.

Relevance to deposit flight prevention: The decision illustrates how resolution law allocates losses and defines the rights of investors when a bank fails. Predictable loss-allocation rules can support market discipline and reduce uncertainty during a crisis.

However, the case principally concerns investors holding capital instruments, not ordinary depositors seeking repayment of covered deposits.

CASE 6: AERIS INVEST SÀRL v SINGLE RESOLUTION BOARD

Citation: Case C-874/19 P, Court of Justice of the European Union, judgment of 21 December 2021.

Facts: Aeris Invest challenged aspects of the Banco Popular resolution and the treatment of valuation under the Single Resolution Mechanism.

Legal issues: The Court considered the meaning and consequences of the definitive valuation provisions under Article 20 of Regulation (EU) No 806/2014.

Decision: The Court dismissed the appeal.

Legal principle: The legal consequences of a post-resolution valuation depend on the statutory conditions and the particular resolution measure. The valuation provisions do not create an unrestricted right to additional compensation.

Relevance to deposit flight prevention: The decision demonstrates the importance of a predictable legal framework for dealing with the consequences of bank failure. Clear rules governing valuation, loss allocation and compensation can help make resolution credible.

A credible resolution mechanism can reduce uncertainty about how a bank's failure will be managed, although it cannot guarantee that depositors will never withdraw funds during a period of market stress.

CASE 7: AERIS INVEST SÀRL v EUROPEAN COMMISSION AND SINGLE RESOLUTION BOARD

Citation: Case C-535/22 P, Court of Justice of the European Union, judgment of 4 October 2024.

Facts: Aeris Invest appealed aspects of the General Court's earlier judgment concerning the Banco Popular resolution scheme.

Legal issues: The proceedings involved the conditions for adopting a resolution scheme under Regulation (EU) No 806/2014, the duties of the Single Resolution Board, the obligation to state reasons, confidentiality and the protection of property rights.

Decision: The Court of Justice dismissed the appeal.

Legal principle: The legality of a resolution scheme must be assessed under the statutory requirements governing resolution, including the relevant conditions for intervention and the duties imposed on the authorities.

Relevance to deposit flight prevention: The decision reinforces the importance of a functioning and legally accountable resolution system. Authorities must be able to respond rapidly to a failing bank, but they remain bound by the legal framework governing their actions.

The case also illustrates why judicial review is important to the legitimacy of crisis-management measures. Financial stability and depositor protection are public objectives, but they must be pursued through legally authorised procedures.

6.8 Combined significance of the seven decisions

Taken together, the seven decisions establish several important lessons.

First, financial stability is a recognised public objective capable of supporting urgent resolution measures where statutory requirements are satisfied.

Second, resolution law distinguishes between covered depositors, other creditors and shareholders. Their legal rights and exposure to losses are not identical.

Third, the existence of a public interest in preserving financial stability does not remove the requirement for lawful decision-making, appropriate reasoning and compliance with applicable safeguards.

Fourth, a credible resolution framework must address not only whether a bank should be resolved but also how its assets and liabilities are valued, how losses are allocated and whether compensation is legally available.

Finally, the cases show that resolution and depositor protection are complementary rather than interchangeable. Deposit insurance provides protection within prescribed limits, while resolution law seeks to maintain critical functions and manage the consequences of failure.

7. INTERNATIONAL REGULATORY STANDARDS

7.1 Basel Committee on Banking Supervision

The Basel Committee on Banking Supervision develops international standards designed to strengthen the regulation, supervision and risk management of banks.

Its Basel III framework introduced or strengthened prudential measures intended to improve capital adequacy, leverage controls and liquidity resilience.

Two major liquidity standards are particularly relevant.

Liquidity Coverage Ratio: The LCR seeks to ensure that banks maintain sufficient high-quality liquid assets to withstand a prescribed short-term liquidity stress scenario.

Net Stable Funding Ratio: The NSFR seeks to promote stable funding over a longer time horizon by comparing available stable funding with required stable funding.

The Basel framework also emphasises sound liquidity risk management, stress testing, governance and contingency funding planning.

Basel standards are not automatically domestic legislation in every jurisdiction. They require implementation through the applicable national or regional legal and regulatory framework.

Spain implements relevant prudential requirements substantially through the European Union framework. India implements applicable liquidity and prudential requirements through RBI regulations and directions.

7.2 Financial Stability Board

The Financial Stability Board (FSB) develops international policy recommendations and standards intended to strengthen financial stability.

Its Key Attributes of Effective Resolution Regimes for Financial Institutions provide a framework for managing failing financial institutions while preserving critical economic functions and limiting the use of public funds.

The framework emphasises effective resolution powers, resolution planning, cooperation between authorities, continuity of critical functions and arrangements for allocating losses.

These principles are relevant to deposit flight because uncertainty about how a bank will be managed during failure can intensify withdrawals.

An effective resolution framework reduces that uncertainty by providing a structured mechanism for dealing with a failing institution.

The FSB's standards are international policy instruments rather than a substitute for the domestic legislation required to confer legal powers on national authorities.

7.3 International Monetary Fund

The International Monetary Fund (IMF) supports financial stability through surveillance, policy advice, technical assistance and, where appropriate, financial support to member countries.

The IMF's work on banking systems addresses liquidity vulnerabilities, prudential supervision, crisis management and the institutional conditions necessary for financial resilience.

Its Financial Sector Assessment Program evaluates financial-sector vulnerabilities and the quality of financial regulation and supervision in participating jurisdictions.

The IMF does not operate as a universal deposit insurer and does not ordinarily provide direct guarantees of individual bank deposits.

Its contribution to deposit flight prevention is primarily systemic: identifying vulnerabilities, strengthening institutional capacity and supporting policies that improve confidence in the financial system.

7.4 European Union legal instruments

For Spain, several European Union instruments are particularly important:

• Directive 2014/49/EU: Deposit guarantee schemes.
• Directive 2014/59/EU: Bank recovery and resolution.
• Regulation (EU) No 806/2014: Single Resolution Mechanism.
• Regulation (EU) No 575/2013: Prudential requirements for credit institutions, as amended.
• Council Regulation (EU) No 1024/2013: Specific supervisory tasks conferred on the European Central Bank.
• Directive 2013/36/EU: Access to the activity of credit institutions and prudential supervision, as amended.

Together, these instruments create an integrated framework for bank supervision, deposit protection and resolution.

They do not eliminate every risk of deposit flight, but they provide mechanisms intended to reduce the likelihood of bank failure and manage its consequences when it occurs.

7.5 Financial Action Task Force standards

The Financial Action Task Force (FATF) develops international standards concerning money laundering and terrorist financing.

Its recommendations influence national laws requiring customer due diligence, beneficial ownership identification, suspicious transaction reporting and appropriate controls.

These requirements are relevant to banking operations because banks must identify customers and comply with applicable financial-crime obligations.

However, FATF standards should not be mischaracterised as a general deposit flight prevention code. Their primary purpose is to protect the integrity of the financial system against money laundering, terrorist financing and related risks.

Compliance-related account restrictions may sometimes affect access to deposits, but such restrictions arise from the applicable legal obligations and facts of the individual case.

7.6 General principles of financial stability

Across the international regulatory framework, several principles recur:

1. Adequate liquidity buffers and stable funding.
2. Effective governance and risk management.
3. Timely supervisory intervention.
4. Credible depositor protection.
5. Effective crisis-management and resolution powers.
6. Cross-border cooperation and information sharing.
7. Transparent and accurate communication.
8. Legal accountability and protection against arbitrary intervention.

These principles are mutually reinforcing. A deposit guarantee may be less effective if public confidence in its administration is weak, while liquidity regulation may be insufficient if authorities lack the capacity to intervene promptly during a crisis.

8. PRACTICAL LEGAL AND REGULATORY MECHANISMS FOR PREVENTING DEPOSIT FLIGHT

8.1 Early warning systems

Banks should maintain systems that monitor sudden changes in deposit balances, customer concentration, unusual transaction patterns and changes in funding conditions.

Early warning indicators can help identify a developing liquidity problem before withdrawals become unmanageable.

Supervisors should be able to evaluate these indicators and require appropriate corrective action where necessary.

8.2 Contingency funding plans

A contingency funding plan identifies the actions a bank may take when ordinary funding sources become unavailable or substantial withdrawals occur.

The plan should identify available liquid assets, potential secured borrowing, collateral arrangements, alternative funding sources, internal decision-making responsibilities and communication procedures.

Plans should be tested against severe but plausible scenarios rather than merely describing ideal conditions.

8.3 Deposit concentration management

Banks with highly concentrated deposits may be more vulnerable to rapid withdrawals by a small number of large customers.

Appropriate concentration monitoring, funding diversification and scenario analysis can reduce this vulnerability.

However, concentration risk must be assessed alongside the stability and behaviour of each funding source. A high concentration is a risk indicator, not conclusive evidence that a bank will experience a run.

8.4 Deposit insurance awareness

Clear communication about statutory deposit protection can help reduce unnecessary panic.

Authorities should explain eligibility, coverage limits, aggregation rules and the procedures that apply if a bank fails.

Communication must remain accurate. Authorities should not imply that every deposit, financial instrument or investment product is guaranteed when the applicable legislation does not provide such protection.

8.5 Crisis communication

Unclear, delayed or contradictory announcements may intensify uncertainty.

Banks and regulators should coordinate communication, provide verified information and avoid unsupported assurances.

At the same time, confidentiality requirements may limit the information that can lawfully be disclosed during supervisory or resolution proceedings.

The challenge is to provide enough information to maintain confidence without compromising market integrity, resolution effectiveness or legally protected information.

8.6 Emergency liquidity support

Central bank liquidity facilities may help eligible institutions meet temporary funding needs, subject to the applicable rules.

Such assistance can be particularly important where an otherwise viable institution experiences a sudden liquidity shock.

However, liquidity support does not automatically solve insolvency. Lending additional funds to an institution with fundamentally inadequate assets may merely postpone the recognition of losses.

Authorities must therefore distinguish temporary liquidity problems from deeper solvency problems.

8.7 Orderly resolution

Where preventive measures are insufficient, a credible resolution framework can preserve critical banking services and manage the distribution of losses in accordance with the law.

The Spanish experience with Banco Popular demonstrates that resolution can be used to address a bank's acute financial difficulties without necessarily interrupting all its essential banking functions.

Effective resolution requires preparatory planning, reliable valuations, clearly defined authority, operational continuity and coordination between relevant institutions.

9. CRITICAL EVALUATION

9.1 Strengths of the Spanish framework

Spain benefits from an integrated European framework combining prudential supervision, deposit guarantee schemes and resolution mechanisms.

Its principal strengths include common prudential standards, supervisory coordination, a statutory deposit guarantee scheme and a structured approach to dealing with failing institutions.

The Banco Popular experience demonstrates the importance of the ability to intervene rapidly when a bank faces acute liquidity stress.

However, the experience also shows that resolution can generate extensive litigation concerning valuation, property rights, procedural safeguards and the allocation of losses.

9.2 Strengths of the Indian framework

India benefits from a central banking institution with substantial supervisory and regulatory responsibilities, statutory liquidity requirements, deposit insurance and powers to intervene in distressed banking institutions.

These arrangements provide tools for monitoring vulnerabilities and managing financial distress.

Nevertheless, the effectiveness of the framework depends on timely supervision, credible public communication, adequate funding and liquidity management, and clear procedures for protecting depositors during a bank's reconstruction or failure.

9.3 Common challenges

Both jurisdictions face challenges arising from digital banking, concentrated deposits, rapid information dissemination and interconnected financial markets.

Digital banking allows customers to transfer funds rapidly, potentially increasing the speed of a bank run.

Social media and messaging platforms can amplify unverified claims, making confidence more sensitive to rumours.

Large institutional depositors may also withdraw funds more rapidly than the assumptions used in ordinary liquidity models suggest.

Consequently, deposit flight prevention must evolve with technological and behavioural changes. Static prudential requirements alone may be insufficient if banks and supervisors fail to account for the speed and concentration of modern deposit withdrawals.

9.4 Need for a balanced approach

A regulatory response must balance three objectives:

• Protecting depositors and maintaining confidence.
• Preserving the safety and soundness of financial institutions.
• Respecting lawful customer rights and ensuring accountable public administration.

Overly weak regulation can expose depositors and the financial system to serious harm. Excessively rigid restrictions can undermine confidence, interfere with legitimate transactions and create legal uncertainty.

The most effective approach combines preventive regulation with credible deposit protection and carefully designed crisis-management powers.

10. RECOMMENDATIONS

First, banks should strengthen real-time monitoring of deposit flows and liquidity positions, particularly where funding is concentrated among a small number of customers.

Second, supervisors should ensure that contingency funding plans address digital bank runs, correlated withdrawals and the possibility that liquid assets may become difficult to monetise during a crisis.
