- EBA proposed on June 26 increasing penalties under MiCA, including up to 12.5% of annual turnover for some stablecoin-related breaches.
- ESMA is coordinating cross-border supervision and pressing national competent authorities to act against unauthorized crypto providers starting July 1, while the EBA directly oversees significant stablecoin issuers.
- Czech National Bank can fine unauthorized crypto service providers up to 118.5 million Czech koruna (~$5.6 million), 5% of annual turnover if higher, or twice the unlawful benefit obtained — the most concrete national penalty disclosed.
- Czech Republic, Bulgaria, Luxembourg and Italy have all issued notices reminding crypto firms the MiCA transition period has ended and urging providers without authorization to wind down operations.
- GrlicaLaw founder Ivo Grlica warned that differing NCAs create regulatory arbitrage risks despite MiCA's harmonization goal, with enforcement likely to spread into national courts and criminal-law systems.
- Parfin VP Peter Bidewell said uneven supervisory approaches across member states could undermine MiCA's harmonization push, while France's AMF, the Netherlands' AFM and Germany's BaFin declined to detail their enforcement plans before publication.
Why it matters: MiCA was designed to create a single EU crypto rulebook, but with 27 national regulators each setting their own enforcement pace, unauthorized firms can shop for the weakest supervisor — and ESMA's July 1 deadline for NCA action will test whether the system delivers uniform enforcement from day one or immediately fragments.
