MiCA Regulation as a Catalyst for Stablecoin Payments
The entry into force of the MiCA Regulation (Markets in Crypto-Assets) in the European Union has marked a turning point for stablecoins. By establishing a clear legal framework for issuers and service providers, MiCA reduces the legal uncertainty that had long hindered mass adoption. In Spain, the Spanish National Securities Market Commission (CNMV) has published reports analyzing this new scenario. In its 2026 Annual Report, the CNMV highlights that European regulation creates conditions for stablecoins to be used as a means of payment, provided they meet transparency, reserve, and supervision requirements.
However, the regulator warns that the risk of depeg persists, especially with unauthorized issuers. MiCA requires issuers to maintain liquid reserves and be registered, but investors must understand that no stablecoin is entirely free from counterparty risk. Still, the regulatory framework is an improvement over the previous legal vacuum, where unbacked promises were abundant.
What Changes with MiCA for Stablecoins in Europe?
MiCA classifies stablecoins into two categories: asset-referenced tokens (ART) and electronic money tokens (EMT). The former are backed by a basket of assets, the latter by fiat currency one-to-one. Both must obtain authorization from the central bank or competent authority. This affects giants like USDT and USDC, which will need to adapt to operate legally in the EU.
In Spain, the CNMV noted in its January 2026 Report on the State of Digital Assets that many stablecoins will not meet the new requirements, potentially reducing available supply. However, this is not necessarily negative: it limits exposure to assets of dubious solvency and encourages the issuance of regulated stablecoins, such as Société Générale's EURCV or Banking Circle's EURI.
For retail investors, the main advantage is that stablecoins under MiCA will enjoy redemption rights and consumer protection similar to those of electronic money. But compliance costs (audits, reserves) will likely be passed on as higher transaction fees.
Real Cases in Spain: Business Alliances and Licenses
The industry is responding. In February 2026, OKX obtained a European payment license under MiCA, as reported by Finect. This allows it to offer custody and transfer services for stablecoins, as well as issue a crypto card linked to these assets. The news is relevant because it shows global exchanges see MiCA as an opportunity to expand in the Spanish market.
On the corporate side, Prosegur Crypto and Minos Global partnered with Indra to develop stablecoin payment solutions for businesses, according to Cinco Días in April 2026. The alliance aims to integrate Prosegur's security infrastructure with Minos' blockchain technology and Indra's technological reach. This will allow Spanish companies to accept stablecoins as payment, with real-time settlement and lower costs than traditional transfers.
These examples show a qualitative shift: we are no longer talking about speculation, but about real uses in commerce. However, mass adoption still requires user-friendly tools for merchants and consumer confidence in the stability of these assets.
Risks and Taxation: What Investors Should Watch
Despite regulatory progress, stablecoins are not without risks. The main one is depeg risk: the value deviating from its peg due to reserve failures or market panic. MiCA attempts to mitigate this with periodic audits, but it does not eliminate the possibility in extreme events.
Another risk is the counterparty risk of the issuer. Even if regulated, an issuer could go bankrupt. Therefore, it is crucial for investors to verify that the stablecoin is issued by an entity authorized by the CNMV or the ECB.
Regarding taxation, in Spain stablecoins are considered cryptocurrencies for personal income tax purposes. If used in payments, the transfer generates a capital gain or loss. The Tax Agency requires declaring each operation, which entails a significant administrative burden for the average user. MiCA does not harmonize taxation, so each country maintains its own rules. Investors must keep a detailed record of all transactions, even low-value ones.
Additionally, the CNMV's crypto-asset glossary recommends not investing more than one can afford to lose, and in the case of stablecoins, remember that they are not guaranteed by the Deposit Guarantee Fund.
