USDC overtakes USDT in euro stablecoin trading as EU rules reshape market: Kaiko
Circle's USDC has overtaken Tether's USDT in stablecoin trading against the euro, now accounting for 56% of such trading, up from just 10% in January 2024, according to Kaiko data.
The shift accelerated after major exchanges restricted USDT trading for customers in the European Economic Area under the Markets in Crypto-Assets Regulation (MiCA). USDC has also overtaken USDT in euro-denominated trading liquidity, with its order books now roughly 40% deeper than its rival's.
Tether remains the larger stablecoin globally, with a circulating supply about 2.5 times that of USDC. Kaiko described stablecoin-to-euro trading pairs as a 'main on-ramp and off-ramp for European customers,' allowing them to exchange euros for US dollar-pegged stablecoins when entering or exiting cryptocurrency markets.
EU regulatory shift
The findings come about two weeks after the European Banking Authority designated USDC as the EU's first 'significant e-money token' under MiCA, a classification that places the stablecoin under direct EBA supervision and subjects its issuer to additional regulatory requirements.
US regulatory outlook
Kaiko said the US is taking a similar approach to stablecoin regulation under the GENIUS Act, raising the possibility that American exchanges could see the same shift in trading activity observed in Europe. On Oct. 21, the Office of the Comptroller of the Currency issued its first final rule under the law, establishing reserve and redemption requirements for stablecoin issuers under its supervision, effective Jan. 18, 2027.
Beginning in July 2028, US platforms will also face restrictions on offering stablecoins from issuers that do not meet the law's approval requirements. The regulatory changes could favor Circle, which has pursued authorization in both Europe and the US. Tether has taken a different approach, launching a separate US-focused stablecoin, USAT.
