Banking Law and ESG Rating Use in Banking Decisions in Kuwait

Introduction

Environmental, Social and Governance (ESG) ratings are increasingly used by banks to evaluate risks that may not be fully captured by traditional financial indicators. In Kuwait, banks may consider ESG ratings or internally developed ESG scores when making lending, investment, project-finance, counterparty and portfolio-management decisions.

An ESG rating can evaluate matters such as carbon emissions, environmental compliance, employee practices, corporate governance, board effectiveness, business ethics and sustainability-related controversies. However, an ESG rating is not the same as a traditional credit rating. A credit rating primarily considers the ability of an entity to meet financial obligations, whereas an ESG rating generally evaluates sustainability risks, practices or exposures according to the methodology of the particular rating provider.

Kuwait does not currently have a single banking statute requiring every credit decision to be determined by an external ESG rating. Instead, ESG ratings operate within the broader framework of banking risk management, corporate governance, sustainable finance and increasingly detailed sustainability disclosures. Kuwait's sustainability framework has recently strengthened: Premier Market companies became subject to mandatory sustainability-reporting requirements beginning in 2026 for the 2025 reporting year, while Boursa Kuwait's updated ESG guidance incorporates international frameworks including IFRS S1 and IFRS S2.

Legal and Regulatory Framework

The Central Bank of Kuwait Law No. 32 of 1968 concerning Currency, the Central Bank of Kuwait and the Organization of Banking Business, as amended, provides the foundation of banking regulation in Kuwait.

The Central Bank of Kuwait (CBK) supervises banks and establishes prudential requirements relating to capital, credit risk, governance, internal controls and risk management. ESG ratings used by a bank should therefore operate within its overall risk-management framework rather than replace conventional prudential analysis.

The Companies Law No. 1 of 2016, as amended, is also relevant to corporate governance and management responsibilities.

For listed banks and other listed companies, Law No. 7 of 2010 concerning the Establishment of the Capital Markets Authority and Regulating Securities Activities, together with its Executive Bylaws, establishes important disclosure and governance requirements.

Kuwait's sustainability-disclosure regime has become considerably more important. CMA Circular No. 04 of 2025 made sustainability reports mandatory for Premier Market companies beginning in 2026, requiring reports covering 2025.

Meaning of ESG Ratings in Banking

An ESG rating normally converts sustainability information into a score, category or risk assessment.

Environmental factors may include climate exposure, pollution, energy consumption, waste, water management and environmental compliance.

Social factors can include employee treatment, occupational safety, human rights, customer protection and community impacts.

Governance factors commonly include board structure, internal controls, executive accountability, corruption prevention and shareholder rights.

A Kuwaiti bank can obtain such information from borrowers, public disclosures, sustainability reports, specialized rating providers and its own due-diligence process.

The bank may then incorporate ESG information into its internal risk assessment.

ESG Ratings and Credit Decisions

ESG ratings can be particularly useful in corporate lending.

Consider a borrower that appears financially strong but operates in an industry facing substantial environmental regulation. Future regulatory requirements could increase its operating costs, reduce asset values or weaken cash flows.

An ESG assessment can identify these vulnerabilities before they become conventional credit problems.

A bank might therefore consider ESG information when determining loan approval, internal risk classification, loan maturity, collateral requirements, covenants or monitoring intensity.

However, an ESG score should generally be treated as one input rather than an automatic decision. Different ESG rating providers can use different methodologies and reach different conclusions about the same company.

Internal ESG Scoring

Banks do not necessarily have to rely entirely upon external ESG rating agencies.

A Kuwaiti bank may develop its own ESG scoring methodology tailored to its portfolio.

For example, it can classify borrowers according to industry, environmental exposure, governance quality and sustainability-related risks.

An internal model may be especially useful where external ESG ratings are unavailable for small and medium-sized companies.

Recent Kuwaiti banking disclosures illustrate this movement in practice. Published sustainability reporting by a Kuwaiti bank describes incorporating an ESG risk-scoring tool into credit decisions to assess borrowers' environmental and social risk exposure and indicates that such assessments may influence financing terms and investment decisions.

ESG Ratings in Investment Decisions

ESG ratings can also influence investment activities.

A bank managing investment portfolios may use ESG scores to identify companies presenting significant environmental, social or governance risks.

ESG information can support portfolio screening, investment limits, sector analysis and enhanced due diligence.

Banks should nevertheless avoid blindly excluding companies simply because an external provider gives them a particular score. The bank should understand what the rating measures and whether the methodology is appropriate for the relevant decision.

ESG Rating Methodology Risk

One of the biggest legal and risk-management issues is methodology risk.

Two rating agencies can assign significantly different ESG assessments to the same company because they may measure different factors, assign different weights or use different data.

One provider might heavily emphasize carbon emissions, while another emphasizes corporate governance.

Banks should therefore understand the scope, assumptions, data sources and limitations of ratings used in important decisions.

External ratings should not become substitutes for independent banking judgment.

Data Quality

ESG ratings depend heavily upon underlying information.

Incomplete, outdated or inaccurate sustainability information can produce misleading ratings.

Kuwait's expanding sustainability-reporting framework can improve the amount and comparability of information available to banks. Boursa Kuwait's 2026 ESG Disclosure Guide reflects ISSB standards, including IFRS S1 and IFRS S2, and encourages clearer methodologies, reporting boundaries and governance arrangements.

This can improve the information environment within which ESG-based banking decisions are made.

Greenwashing Risk

Banks must also consider greenwashing.

A borrower may portray itself as environmentally responsible without sufficient supporting evidence. If a bank accepts such representations without reasonable verification, its ESG assessment may underestimate risk.

Similarly, a bank should be cautious about advertising loans or portfolios as “green” or “ESG compliant” merely because an external score has been used.

The classification should have a defensible methodology and supporting evidence.

Case Laws and Legal Authorities

There are not six well-established published Kuwaiti judicial decisions specifically concerning ESG ratings in bank credit decisions. ESG rating integration is relatively new. It would therefore be inaccurate to invent Kuwait-specific cases. The following comparative cases provide useful principles concerning ratings, financial information, environmental risk, governance and reliance on external assessments.

1. Abu Dhabi Commercial Bank v. Morgan Stanley & Co., 651 F. Supp. 2d 155 (S.D.N.Y. 2009)

The dispute involved investment products and credit ratings that investors alleged were misleading.

The case demonstrates that ratings should not automatically be treated as unquestionably reliable.

For Kuwaiti banks using ESG ratings, the practical principle is important: an external rating does not eliminate the institution's responsibility to conduct appropriate due diligence.

2. Bathurst Regional Council v Local Government Financial Services Pty Ltd (No 5) [2012] FCA 1200

This major Australian litigation involved complex financial products and credit ratings.

The court considered responsibilities associated with ratings and representations concerning investment risk.

Its relevance to ESG ratings is that institutions should understand how a rating was produced rather than simply relying upon the rating label.

3. Basic Inc. v. Levinson, 485 U.S. 224 (1988)

This leading securities decision concerned material information relevant to investors.

The broader principle of materiality is useful for ESG banking decisions. ESG information becomes especially significant when it could meaningfully affect financial risk or decision-making.

Banks should therefore focus on financially significant ESG factors rather than treating every sustainability indicator as equally important.

4. Matrixx Initiatives, Inc. v. Siracusano, 563 U.S. 27 (2011)

The U.S. Supreme Court rejected an inflexible approach under which information could be considered immaterial merely because it did not satisfy a predetermined numerical threshold.

The comparative lesson for ESG scoring is particularly useful.

A serious governance controversy or environmental exposure may be relevant even where its immediate financial cost cannot yet be precisely quantified.

5. United States v. Bestfoods, 524 U.S. 51 (1998)

This case concerned corporate relationships and environmental liability.

It illustrates how environmental problems can develop into substantial legal and financial liabilities.

For a Kuwaiti bank, such risks can justify considering environmental performance when evaluating borrowers operating in environmentally sensitive industries.

6. ClientEarth v Shell plc [2023] EWHC 1137 (Ch)

This UK proceeding concerned directors' duties and climate strategy.

The court emphasized the considerable discretion directors possess when balancing competing considerations in corporate decision-making.

The case provides an important lesson for ESG-based banking decisions: sustainability considerations may be relevant, but directors and management must still exercise independent commercial judgment rather than automatically following one ESG indicator.

7. TSC Industries, Inc. v. Northway, Inc., 426 U.S. 438 (1976)

This case established an influential approach to determining whether information is material.

For ESG ratings, the principle supports concentrating on information that would meaningfully alter the overall assessment of a company or transaction.

A bank's ESG system should therefore distinguish genuinely significant sustainability risks from insignificant data.

Governance and Board Responsibility

The use of ESG ratings should be governed by appropriate internal policies.

The board or senior management should determine how ESG considerations fit within the institution's risk appetite and business strategy.

Credit committees should understand whether an ESG rating can influence approval decisions and how much weight it receives.

Risk-management teams should validate internal methodologies and review important third-party data sources.

Compliance teams should examine whether sustainability representations are accurate and consistent.

Internal audit can independently examine whether ESG-rating policies are actually followed.

Human Oversight

Banks should avoid fully mechanical decision-making based solely upon ESG scores.

A company receiving a poor rating may have legitimate reasons for the result, such as incomplete data or differences between rating methodologies.

Conversely, a high ESG score does not establish that the borrower has strong repayment capacity.

Human review therefore remains important.

Creditworthiness, cash flow, leverage, collateral, industry conditions, management quality and conventional financial information should continue to form part of banking decisions.

Fairness and Transparency

ESG-based decisions should also be reasonably consistent.

Borrowers operating in comparable circumstances should generally be assessed according to comparable standards.

Where ESG factors materially influence financing conditions, banks should maintain appropriate documentation explaining the factors considered.

This is particularly important where automated models or third-party ESG scores are incorporated into credit systems.

Current Kuwait Market Development

Kuwait's ESG environment is becoming more sophisticated. The CMA reported in July 2026 that it had issued its second sustainability report and highlighted continuing efforts to consolidate sustainability standards within Kuwait's capital markets.

The banking market also provides concrete evidence that ESG ratings are becoming commercially relevant. For example, Kuwait Finance House's published 2025 sustainability material reports an MSCI ESG rating of A and a Sustainalytics ESG Risk Rating of 24.5, classified as Medium Risk.

These developments do not mean that an ESG rating has become a legally prescribed substitute for credit analysis. Rather, they demonstrate that ESG measurement and disclosure are increasingly part of Kuwait's financial information environment.

Practical Compliance Framework

A Kuwaiti bank using ESG ratings should first establish a clear ESG policy defining when ratings are relevant. It should determine whether external ratings, internal scores or a combination will be used.

The institution should validate important data, document methodologies and periodically review rating models.

Material discrepancies between different ESG providers should be investigated rather than automatically resolved by choosing the most favorable rating.

Banks should also separate ESG risk ratings from conventional credit ratings. The two systems may interact, but they answer different questions.

Finally, the institution should maintain records explaining how ESG information influenced significant lending or investment decisions.

Conclusion

The use of ESG ratings in banking decisions in Kuwait is an emerging component of prudential risk management, sustainable finance, corporate governance and investment analysis.

Kuwaiti law does not currently establish a simple rule under which banks must approve or reject financing according to a particular external ESG score. Instead, ESG information can operate as an additional risk-management tool within the broader framework supervised by the Central Bank of Kuwait and, for listed entities and capital-market activities, the Capital Markets Authority.

Recent developments—including mandatory sustainability reporting for Premier Market companies and Boursa Kuwait's updated ESG Disclosure Guide—are improving the sustainability information available to financial institutions.

The principal legal and banking lesson is that ESG ratings should support, not replace, independent credit and investment judgment. Banks should understand rating methodologies, verify material information, address greenwashing and data-quality risks, preserve human oversight and document how ESG considerations affect important financial decisions.

Because there are not six established Kuwaiti court judgments specifically concerning ESG-rating use in banking decisions, comparative cases should be used only for their persuasive principles and should not be presented as binding Kuwait precedents.
