USDC stablecoin volume hits record $1.79T in June, surpassing Tether as banks adopt digital currencies.

Circle's USDC stablecoin led the stablecoin market in the first half of 2026, accounting for about 70% of adjusted transaction volume, far ahead of Tether's USDT at 25%. In June 2026, stablecoin transaction volume reached a record $1.79 trillion, a 63% increase from May and 125% from June 2025, driven by growing adoption from banks and financial institutions like Standard Chartered and BNY Mellon. This surge reflects a broader shift toward using established fiat-pegged digital assets for faster settlements and treasury operations. The first half of 2026 saw $8.82 trillion in adjusted stablecoin volume, indicating strong momentum in the digital currency space.
