MiCA, one year in — a working hypothesis
The framework is more operationally tractable than its critics predicted and less transformative than its advocates claimed. Both camps should update.
The Markets in Crypto-Assets Regulation took full effect in late 2024 and has now had a full calendar year of operation in the field. The debate preceding its entry into force was loud; the operational evidence since has been quieter and, we would argue, more interesting than either camp anticipated.
The critics predicted that MiCA's reserve requirements under Article 44, the segregation mandates, and the authorisation process would push stablecoin issuance offshore. This has not happened to the extent predicted. Circle and Paxos both completed their Irish and Finnish authorisations respectively within the transitional period, and the issuance volume denominated in EUR stablecoins has grown, not shrunk, over the past twelve months.
The advocates predicted that MiCA would unlock institutional tokenised-asset adoption across the EU. This has also not happened to the extent predicted. Institutional adoption has grown steadily but not dramatically, and the growth is concentrated in a small number of jurisdictions (Luxembourg, Ireland, the Netherlands) that were already moving regardless of MiCA.
The most interesting finding from a year of operational evidence is that MiCA is essentially plumbing. It resolved a set of legal uncertainties that were blocking some participants; it imposed operational costs on others; and the net effect has been the emergence of a working European stablecoin market that is neither dramatically larger nor dramatically smaller than it would have been without the regulation.
This is, in policy terms, a success. Regulations that merely resolve legal uncertainty without dramatically reshaping markets are the ones that age well. MiCA looks like it will be one of them.
The remaining open questions are operational rather than legal. How do fund administrators process MiCA-compliant stablecoin cash legs? How do Irish-authorised stablecoins interact with non-EU counterparties? What happens when a MiCA-compliant stablecoin seeks authorisation in the US under the GENIUS Act? These questions are boring in the best sense of the word: they are the detailed operational plumbing that signals the market is settling in.
