In a historic realignment of global stablecoin liquidity, Circle's USD Coin (USDC) has surpassed Tether (USDT) in euro-denominated trading volume across centralized exchanges. According to data released by market intelligence firm Kaiko, the shift reflects the compounding impact of the European Union’s Markets in Crypto-Assets (MiCA) framework, which enforces rigorous reserve and licensing requirements on fiat-pegged token issuers.
How did MiCA trigger the stablecoin volume flip?
The enforcement of MiCA’s asset-referenced and e-money token provisions earlier this year mandated that stablecoin issuers obtain Electronic Money Institution (EMI) licenses within the European Economic Area (EEA). While Circle proactively secured EMI licensing in France for both USDC and EURC, Tether chose not to pursue the same European authorization framework, expressing skepticism over mandatory commercial bank reserve holding rules.
Consequently, leading Tier-1 exchanges operating within the EEA—including Kraken, Bitstamp, and OKX—began systematically restricting or phasing out non-compliant stablecoin pairs to maintain regulatory conformity. This regulatory divergence catalyzed a rapid migration of market-maker liquidity and institutional order flow into compliant euro and dollar alternatives.

Fresh metrics compiled by Kaiko reveal that USDC now captures the majority of euro-to-stablecoin transaction volume, a milestone historically dominated by Tether. While USDT maintains its global market-cap supremacy in emerging markets and offshore venues, European order books show a distinct liquidity bifurcations where compliance directly determines exchange depth.
Trading desks across the continent have pivoted toward Circle’s ecosystem to mitigate counterparty risk and avoid cross-border regulatory liabilities. Industry analysts note that this trend will likely deepen as the full slate of MiCA directives covering crypto-asset service providers (CASPs) becomes universally enforceable across all member states.
“The structural flip between USDC and USDT in euro-denominated pairs is empirical proof that regulatory frameworks dictate digital asset liquidity corridors. Exchanges and institutional liquidity providers are no longer willing to absorb regulatory arbitrage risk when compliant alternatives are readily integrated.”
With Circle cementing its first-mover regulatory advantage in Europe, market participants anticipate broader adoption of fully licensed euro-native stablecoins alongside dollar-backed equivalents, permanently reshaping Europe's digital asset trading architecture.
