USDC Transfer Volume Hits $32 Trillion as Circle Relies on Reserve Income
Circle's USDC stablecoin has reached a transfer volume of $32 trillion through August 2026, according to Coin Metrics. This is significantly higher than the roughly $8 trillion recorded by USDT over the same period.
The growth in USDC circulation and on-chain transaction volume has been impressive, with Q2 2026 seeing $14.8 trillion in onchain transaction volume, a 151% increase from the previous year. However, despite this growth, Circle still relies heavily on interest income generated by the assets backing USDC.
USDC's transfer volume is driven largely by DeFi activity, with Coin Metrics estimating that about 69% of analyzed USDC volume comes from DEX liquidity provision and 23% from flash loans. Large transactions also play a significant role, with data from Glassnode showing $34.5 billion in USDC transfers above $10 million.
Circle's business remains sensitive to interest rates and USDC circulation, with a decline in interest rates potentially reducing reserve income by up to $737 million over the following 12 months. The company is also launching its Arc blockchain network, which could provide a new revenue stream through transaction fees paid in USDC.
