MiCA Was the Easy Part, Now EU Crypto Faces the Real Test

The Markets in Crypto-Assets regulation went live across the European Union this week. The legislative work is done. People who drafted the text say the harder phase begins now.

Enforcement is the first unknown. National regulators – France's AMF, Germany's BaFin, Italy's Consob – each interpret the same rulebook for their own markets. A license approved in one country is supposed to pass across the bloc under the passporting regime. No one has tested that mechanism at scale. The first cross-border compliance dispute will set a precedent every exchange and stablecoin issuer will watch.

Consolidation is already underway. Smaller issuers and exchanges that lack the capital to meet MiCA's reserve and governance requirements are looking for buyers or winding down. The firms that survive will carry higher compliance costs. That means tighter margins on retail trading fees and stablecoin products. Some of that cost will pass to users – spreads on USDC/EUR pairs, for example, could widen as settlement mechanics change. Exchanges must now hold stablecoin reserves in EU-regulated banks, not just any custodian. That shift alters the balance-sheet math for margin lending and euro-denominated settlement.
