Stablecoins Surpass $7 Trillion in Monthly Settlements as Infrastructure Takes Shape

The stablecoin market has surpassed $7.2 trillion in monthly settlement volume, exceeding the US Automated Clearing House (ACH) network's processing capacity of $6.8 trillion.

This milestone occurred in February 2026 and was followed by a further increase to $7.5 trillion in March 2026.

The GENIUS Act, enacted in July 2025, provided the necessary clarity for institutional capital to invest in stablecoin infrastructure, driving total market capitalization to approximately $307 billion as of September 2026.

Four major players have signaled a shift towards deep integration: Visa became a founding validator on Circle's Arc L1 blockchain, SoFi Bank launched its first stablecoin, SoFiUSD, Binance secured a stake in Circle, and Coinbase partnered with Stablecore to integrate digital asset services into community banks.
