Circle’s USDC surged through the first quarter of 2026, adding roughly $2 billion in supply and pulling ahead of rival Tether at a time when the wider crypto market was contracting. The split between the two largest stablecoin issuers—USDC on the rise while USDT retreated—was the sharpest divergence since the mid‑2022 bear market.
What happened
- USDC supply grew by about $2 billion in Q1, while Tether’s USDT supply fell by roughly $3 billion over the same period.
- Transfer activity for USDC hit a record high in February, and on‑chain trading metrics show rising usage for Circle’s coin.
- Total stablecoin supply reached $315 billion at the end of March, up about $8 billion from the prior quarter (CEX.io).
Why it matters
Institutional preference appears to be driving some of the shift. As Congress edges closer to passing stablecoin legislation, many institutions are favoring US‑regulated issuers like Circle—boosting USDC’s traction in trading and on‑chain flows. That shift comes even as overall crypto markets shrank, underlining stablecoins’ role as a defensive liquidity option inside the ecosystem.
Macro picture and volume trends
- Stablecoins commanded 75% of all crypto trading volume in Q1—the highest share on record—as investors rotated into dollar‑pegged assets rather than exiting crypto entirely.
- Total stablecoin transaction volume for the quarter topped $28 trillion, continuing a streak in which stablecoins process more value annually than Visa and Mastercard combined.
New supply sources: yield‑bearing stablecoins
A notable portion of new issuance in the quarter came from yield‑bearing stablecoins—products that pay returns similar to interest accounts. That segment is now worth about $3.7 billion, with daily trading volumes exceeding $100 million (CoinGecko). These instruments have sparked pushback from traditional banks, which are lobbying Congress to restrict stablecoins that offer returns on the grounds that they function more like financial instruments than simple payment tools. The regulatory outcome remains undecided and will be pivotal in determining how much room these products have to grow in the U.S. market.
Shifts beneath the surface
Not all metrics were positive for retail users. Retail‑sized transfers—those linked to individual users—fell 16% in Q1, the steepest single‑quarter decline on record. Much of the activity gap was filled by automated and algorithmic trading, which accounted for roughly 75% of all stablecoin transaction volume during the period.
Takeaway
CEX.io frames the quarter as one of “structural growth under pressure”: overall stablecoin supply and transaction volumes are growing, but the composition is changing—driven increasingly by institutions, algorithms, and new yield products even as everyday user participation wanes. How regulators handle yield‑bearing stablecoins and where institutional flows go next will be crucial in shaping the sector’s trajectory through the rest of 2026.
