Coinbase will delist stablecoins that fail to meet the European Union's Markets in Crypto-Assets (MiCA) regulations by December 30, 2024. The new rules require stablecoins to have an e-money license in at least one EU member state. Non-compliant stablecoins like Tether's USDT could be affected, as they currently do not meet the necessary requirements. In contrast, Circle's USDC, which is already compliant with MiCA, will remain supported, and users in the European Economic Area (EEA) will be able to convert non-compliant tokens into approved alternatives. This move is part of broader efforts by Coinbase to align with the EU’s stricter crypto oversight.
