Banking Law and Digital Cash Alternatives Regulation in Spain

Introduction

Digital cash alternatives are electronic forms of value used instead of physical banknotes and coins. They include electronic money, mobile wallets, prepaid cards, instant-payment applications, stablecoins, tokenised deposits and the proposed digital euro. Spain regulates these alternatives through a combination of European Union law and national banking legislation.

The main legal objective is to encourage innovation while protecting the stability of money, payment systems and consumers. Spanish law therefore distinguishes between regulated electronic money, bank-account payments, crypto-assets and central-bank money. A product cannot be treated as “cash” merely because it is stored digitally or transferred through a mobile application.

Legal and Regulatory Framework

Electronic money in Spain is principally governed by Law 21/2011 on Electronic Money, together with EU electronic-money rules. Electronic money is a monetary value stored electronically, issued after receipt of funds, accepted by persons other than the issuer and redeemable at par value. It may be issued by authorised credit institutions or electronic-money institutions supervised by the Banco de España.

Payment services are regulated mainly through Royal Decree-Law 19/2018, which implements the second Payment Services Directive. Payment institutions and account-information or payment-initiation service providers must obtain authorisation, protect customer funds, apply strong customer authentication and follow transparency and complaint-handling rules.

Customer funds received for payment or electronic-money services must be safeguarded. Depending on the legal structure, funds may be kept in a separate account or covered by an insurance or comparable guarantee. These funds are not ordinary deposits and should not be presented as deposits protected by the Spanish Deposit Guarantee Scheme unless they legally qualify as deposits.

Spain also applies Law 10/2010 on the prevention of money laundering and terrorist financing. Payment institutions, electronic-money institutions and registered virtual-asset service providers must identify customers, verify beneficial owners, monitor transactions and report suspicious activity. The Bank of Spain maintains registration requirements for certain providers exchanging virtual currency for fiat money or offering custodial wallet services.

The Markets in Crypto-Assets Regulation, or MiCA, applies directly throughout the European Union. It regulates crypto-asset service providers, asset-referenced tokens and electronic-money tokens. A stablecoin that qualifies as an electronic-money token must generally be issued by an authorised credit institution or electronic-money institution. A platform that provides payment functions may also require a separate payment-services or electronic-money authorisation.

The Digital Operational Resilience Act imposes technology-risk duties on financial entities and important ICT providers. It requires incident reporting, testing, outsourcing controls and operational-resilience planning. The General Data Protection Regulation also applies to personal data processed through wallets, payment applications and digital-identity systems.

Main Digital Cash Alternatives

Electronic money is the most established private digital cash alternative. Examples include prepaid balances, payment wallets and certain mobile-money products. The issuer must repay the holder at par value and cannot use customer funds as if they were its own money.

Mobile payment systems such as instant account-to-account applications normally transfer bank deposits rather than create new money. Their regulation depends on the payment service being provided, the role of the intermediary and whether the provider has access to the customer’s payment account.

Stablecoins may attempt to maintain a stable value by reference to a fiat currency or reserve assets. Under MiCA, asset-referenced tokens and electronic-money tokens require governance, reserve, redemption, disclosure and prudential controls. Issuers must manage liquidity and ensure that holders are not misled about convertibility or the quality of reserve assets.

Tokenised bank deposits are different from stablecoins. A tokenised deposit represents a claim against a bank, while a stablecoin represents a claim against its issuer under the terms of the token. The legal distinction affects insolvency, redemption, deposit protection and monetary stability.

The digital euro would be a central-bank digital form of euro cash, if and when the EU legislation is adopted and the Eurosystem decides to issue it. It would not be a private cryptocurrency. Banks and payment providers could act as intermediaries, but the digital euro would remain a public monetary instrument rather than a normal bank deposit.

Consumer, Safeguarding and Supervisory Duties

Providers must give customers clear information about fees, redemption, transaction limits, complaints, fraud liability and the legal status of the funds. They must not imply that an unregulated crypto-token has the same protection as a euro balance held with an authorised bank.

Operational safeguards include strong authentication, secure software, encryption, access controls, fraud monitoring, incident-response procedures and business continuity. Outsourcing a wallet or cloud service does not remove the regulated institution’s responsibility.

Providers must also protect customer funds from insolvency risk. Reconciliation should be continuous, records must be accurate and customer money must be separated from operational funds. Where stablecoins are involved, the issuer must explain reserve composition, redemption rights and risks of de-pegging.

Supervisors may impose sanctions, restrict activities or withdraw authorisation when an institution provides services without permission, misuses customer funds, fails to report suspicious activity or has inadequate technological controls.

Case Laws

In Hedqvist, Case C-264/14, the Court of Justice of the European Union treated the exchange of Bitcoin for traditional currency as a VAT-exempt transaction involving a means of payment. The case recognised the economic function of cryptocurrency without declaring it legal tender.

In T-Mobile Austria, Case C-616/11, the Court considered payment-related charges and the scope of VAT treatment for financial services. It illustrates the importance of analysing the real economic function of a digital payment service.

In Home Credit Slovakia, Case C-42/15, the Court interpreted payment-services transparency and consumer-information duties. The decision supports clear disclosure of charges and contractual conditions in digital-payment products.

In Mc Fadden, Case C-484/14, the Court examined liability connected with internet access used for copyright infringement. Although not a banking case, it demonstrates that technology intermediaries may face legal issues when their systems facilitate unlawful conduct.

In DenizBank, Case C-287/19, the Court considered contactless payment instruments and the circumstances in which a payment instrument may be treated as a means of payment. The case is relevant to mobile wallets, cards and other digital payment interfaces.

In Paysera LT v Lietuvos bankas, Case C-389/17, the Court clarified the scope of payment services and activities that fall outside a payment institution’s authorisation. It confirms that providers must classify their actual services correctly rather than rely on commercial labels.

Conclusion

Spain’s regulation of digital cash alternatives is based on legal classification, authorisation, safeguarding and technological resilience. Electronic money and payment services are established regulated activities. Stablecoins and other crypto-assets are now governed principally through MiCA, AML legislation and operational-resilience rules. The proposed digital euro would represent a separate category of public digital cash.

The central principle is that digital convenience cannot replace legal certainty. Every provider must explain what the customer owns, who owes redemption, whether funds are safeguarded, what protection applies in insolvency and which authority supervises the service.
