Decta Says MiCA-Compliant Euro Stablecoins Jumped 128% Ahead of EU CASP Deadline

Euro-denominated stablecoins that comply with the EU’s Markets in Crypto-Assets Regulation, or MiCA, posted strong growth in the year leading up to the end of the bloc’s crypto-asset service provider transition period, according to a new report from payments infrastructure firm Decta. The report said the combined market capitalization of eight actively issuing and actively traded MiCA-compliant euro stablecoins rose from $295.6 million on June 30, 2025, to $673.9 million on June 28, 2026, a 128% increase. Trading volume also climbed 43.1%, from $47 million to $67.3 million, while the number of tracked compliant euro stablecoins increased from five to eight. Despite that growth, the segment remains small compared with the roughly $300 billion market for dollar-pegged stablecoins, accounting for just 0.22% of that total. The report lands as MiCA authorization requirements for crypto-asset service providers took broad effect from July 1, and as policymakers continue debating whether the framework strengthens the euro stablecoin ecosystem or leaves it less competitive than dollar-backed rivals.
