Circle's $USDC has flipped Tether's $USDT to lead euro-denominated stablecoin trading, capturing 56% of market volume following regulatory constraints imposed under the European Union's Markets in Crypto-Assets (MiCA) framework [1]. Data published by market analytics firm Kaiko indicates that USDC's share of euro trading rose from 10% in January 2024 to its current majority [1]. Euro-denominated liquidity also migrated, with USDC order books recording depths roughly 40% deeper than those of USDT [1]. The divergence gained momentum after digital asset exchanges curbed USDT access for European Economic Area residents to align with MiCA mandates, even as Tether maintains a global circulation approximately 2.5 times larger than USDC [1]. Kaiko highlighted these fiat-to-stablecoin pairs as a primary channel for European investors moving capital in and out of digital assets [1]. This transition mirrors ongoing structural debates around asset compliance examined in the [USDT vs USDC](https://basisdesk.news/news/usdt-vs-usdc) landscape. ## Supervisory Oversight and US Regulatory Parallels The market shift follows a regulatory milestone two weeks prior, when the European Banking Authority formally designated USDC as the European Union's inaugural "significant e-money token" [1]. That classification places Circle under direct EBA oversight and introduces elevated regulatory mandates [1]. Cross-border market dynamics may face similar realignments in North America under the GENIUS Act, Kaiko noted [1]. On Oct. 21, the Office of the Comptroller of the Currency issued its inaugural final framework under that statute, setting reserve and redemption mandates for regulated stablecoin issuers [1]. Those OCC rules take effect on Jan. 18, 2027, ahead of July 2028 statutory restrictions that will bar US trading platforms from listing stablecoins lacking statutory authorization [1]. While Circle has pursued direct compliance across both jurisdictions, Tether has opted to target the market by establishing a dedicated vehicle, USAT [1]. ## FAQ **Why did USDC overtake USDT in euro-denominated trading?** Trading shifted to USDC after major cryptocurrency platforms restricted USDT access for European Economic Area customers to comply with the European Union's MiCA regulation [1]. **What is the EBA's significant e-money token designation?** The classification subjects an authorized stablecoin issuer to direct European Banking Authority supervision and heightened operational and prudential requirements [1]. **When do US stablecoin rules under the GENIUS Act take effect?** The OCC's final rule on reserves and redemptions takes effect on Jan. 18, 2027, while exchange restrictions on unauthorized stablecoins begin in July 2028 [1]. ## Sources 1.
