One of 45. That is the field of e-money tokens notified under Europe’s MiCA rules, and on 14 October the European Banking Authority said USDC is the first to be classed as significant.
The token is issued in the EU by Circle Internet Financial Europe. The EBA said it reached the decision by assessing USDC against the regulation’s criteria.
The label has consequences. Under MiCA, a significant token pulls part of the supervision of its issuer towards the EBA and away from the national authority alone, which makes this a change in who watches Circle, not only a badge. That matters for a token that European exchanges and payment firms increasingly treat as a settlement asset.
For scale, The Block put USDC supply at close to $73 billion, second to Tether’s USDT at about $184 billion, in a dollar stablecoin market of roughly $294 billion. Size is the obvious reading of significance, though the EBA’s note does not say so.
Circle has been building its European position. In September Binance bought $100 million of its shares and agreed to promote USDC on its platform, so the regulator’s attention arrives as the company is trying to grow there.
Significance is a test of reach, not a verdict on quality, and it brings more scrutiny rather than less.
What is missing is the working. The announcement does not say which criterion USDC crossed, how close the other 44 tokens are, or what Circle will do differently once the EBA takes its larger role.
