Cryptocurrency Regulations in Spain

Crypto has become a safe haven in Spain, which allows trading, mining, and use of cryptocurrencies, but without the status of the latter as a legal tender. Currently there is only the Euro as a legal tender in the country (since 1999). Meanwhile, the country is actively implementing the European Union’s Markets in Crypto-Assets (MiCA) regulation in order to be fully enforced by December 2025, by harmonizing a framework across the EU. This way of dealing with this issue represents a compromise between innovation and investor protection, and it makes Spain an attractive target for crypto activities.

Investors and businesses need to follow Spain’s crypto rules to stay legal while building on available market opportunities. A structured regulatory environment makes the crypto system safer through its legal security and it fights fraud better while building trust among users. Spain has two main regulatory bodies to supervise crypto activities: the National Stock Market Commission (CNMV) takes charge of MiCA compliance while the Bank of Spain runs the Virtual Currency Service Provider (VCSP) registration process.

Historical Context

In the first phase, there was no specific legislation on cryptocurrency in Spain, which was under general financial laws but did not accept it as legal tender. Key milestones have been forged along the regulatory path over time.

Establishment of virtual assets (Royal Decree 7/2021, 28 April 2021) and obligatory registration of VCSP with the Bank of Spain.
Introducing the LMVSI and laying the basis for MiCA sanctions under Law 6/2023 (March 17, 2023).
Law 28/2022 (December 21, 2022): Offered tax incentives and regulatory sandboxes to promote blockchain innovation.
Specific to MiCA, Spain accelerated its implementation of MiCA by December 2025 or 6 months before the default timeline of the EU.

The shift from minimal oversight to an innovation-based compliance structure is the evolution that can be seen in this transition.

Regulatory Framework

Key Regulatory Authorities

MiCA compliance is overseen by CNMV and is responsible for regulating the crypto-asset service providers (CASPs) and advertising.
Bank of Spain manages VCSP registration and supervises electronic money and asset-referred tokens under MiCA.

Licensing and Registration Requirements

Registration is mandatory for VCSPs to register with the Bank of Spain and send forms CRIPTO01, CRIPTO03 and CRIPTO05. By 2024, around 100 companies had been registered. Under MiCA:

They must also have been licensed by December 30, 2024.
Entities operating in the space market must be licensed by December 30, 2025, with a simplified procedure during the transition.

AML & KYC Requirements

By virtue of Law 10/2010, VCSPs have to report transactions above EUR 30,000 (cross-border), EUR 1,500 (remittances) and EUR 10,000 (cross-border movements) to SEPBALC. The Regulation (EU) 2023/1113 even requires traceability of transfers, including transfers of non-custodial wallets, greater than or equal to EUR 1,000.

Taxation of Cryptocurrency

Progressive income tax is also used to tax crypto transactions.

Tax Rate

Up to 6,000 19%

6,001–50,000 21%

50,001–200,000 23%

Since January 1, 2024, taxpayers must file:

Form 172 (virtual currency balances)
Form 173 (transactions)
Form 721 (holdings abroad > EUR 50,000)

Regulation of ICOs, STOs, and Other Crypto Assets

If deemed to be public offerings, ICOs might be securities laws. Token security is regulated by Law 6/2023 and they include DLT for the issuance and custody of these assets. An exception is that NFTs are usually unregulated, except when categorized as financial instruments.

Spain’s Crypto Policies

Regulatory Approach to Cryptocurrency Usage

Crypto transactions are allowed and, although not recognized legally as legal tender, nowhere is it illegal to use crypto in Spain. MiCA only applies to assets that are decentralized, from Bitcoin to the DeFi aspects, and does not apply to centralized services, for which it seeks to increase regulatory oversight.

Crypto Mining

There are no special limitations for mining, but the general acts are related to energy consumption and tax.

Government-Backed Initiatives

Blockchain is supported by the Bank of Spain, in particular an EURM stablecoin on Ethereum 2.0, issued by MONEI. Spain is a part of the EU projects on digital currency, like a digital euro, and provides regulatory sandboxes under Law 28/2022 for testing innovations.

Penalties for Non-Compliance

For example, in cases involving fraud or money laundering, non-compliance such as unregistered operation or AML violation can become a serious offence that may result in fines, suspensions or even criminal charges.

Spain’s Approach to Crypto Innovation

Regulatory Sandbox

Law 28/2022 creates sandboxes, which provide a controlled environment where blockchain start-ups can test innovations under a period of one year with regulatory supervision.

Crypto Adoption in Businesses

As more people get into crypto, clear regulations are the fuel to more and more industries, which accept cryptocurrencies for doing business.

Blockchain Development

Spain has been supporting blockchain and blockchain projects where they support stablecoin EURM and projects that fall under the EU alignment.

Notable Challenges and Issues

Inconsistencies in Regulation

Spain’s alignment of national and EU laws during MiCA transition (December 2024–2025) may create some in-between disruptions.

Challenges to Enforcement

The anonymous nature of cryptocurrencies makes enforcing AML and KYC very difficult, as it complicates the decentralized nature of the currency and transactions.

Public Perception

Tech-savvy groups support crypto, while old-fashioned sectors and also the media are skeptical but it is getting accepted.

Regulatory Trends and Future Outlook

Recent Developments

A proactive stance is shown by Spain adopting MiCA by December 2025, before the EU’s July 2026 deadline. Robust licensing processes are being prepared by the CNMV and Bank of Spain.

Predictions for the Future

The full implementation of MiCA is expected to be an appeal to more crypto businesses and will help Spain become a greater crypto hub in the EU. Regulation will be investor-focused yet support innovation.

Global Implications

If Spain adopts MiCA early, this could have an impact on its EU neighbours and global markets, making for harmonized standards across the EU, and even allaying some of the fears around cross-border crypto trade.

Conclusion

In Spain, MiCA’s upcoming implementation is backed up by a crypto-friendly yet cautious approach that ensures a balanced environment that supports innovation and security. To survive, investors and businesses must constantly remain compliant with this changing market. As Spain keeps shaping its crypto landscape, keeping up with regulatory changes is essential.
