The MiCA (Markets in Crypto-Assets Regulation) stablecoin regime, a part of EU's effort to regulate the crypto market, became effective recently. It requires stablecoin issuaries in the European Economic Area to be licensed, potentially increasing operational challenges due to stringent capital, liquidity, and transparency requirements. Significant stablecoins will now be under the direct oversight of the European Banking Authority, and additional restrictions limit the issuance of stablecoins beyond certain transaction thresholds. While companies like Circle are adapting, Tether has opted not to pursue an e-money license, affecting its operational status in the EU.
