Report: Stablecoins average over $400 million in transfers per hour, with 73% of transactions occurring outside U.S. banking hours.

Coinbase has released a report titled "The Always-On Dollar", which notes that in Q3 2026, the average hourly transaction volume of organic stablecoin transfers exceeded $400 million. For the 12-month period ending July 31, approximately 73% of screened stablecoin transfer volume occurred outside U.S. banking hours, highlighting the demand for always-on stablecoin payments. The report shows that adjusted quarterly stablecoin transfer volume has quadrupled since early 2023, reaching $891 billion in Q3 2026. At the current growth rate, this figure is expected to hit $1.5 trillion by the end of 2027. The report also points out that sending $200 via USDC on the Base network saves around 86% in fees compared to traditional payment channels. Additionally, if 80% of global international transactions shift to stablecoin payment networks, global annual GDP could rise by an extra $155 billion. Looking ahead, the report positions stablecoins as a critical payment infrastructure for the AI agent economy. McKinsey forecasts that by 2030, AI agents will drive $3 trillion to $5 trillion in global B2C transactions, and stablecoins can support small transactions including paying task fees between agents, purchasing API calls, and accessing data and computing power on demand.
