Move Over, ACH: Stablecoins Now Handle More Cash Than America's Financial Backbone

In February 2026, stablecoins hit $7.2 trillion in monthly transaction volume, officially surpassing the ACH network's $6.8 trillion for the first time. ACH, the electronic payment workhorse that moves money between US bank accounts, has been the go-to rails for electronic money movement for decades. Stablecoins just said "not today."

The crossover didn't stop there. According to Artemis data, stablecoin volume climbed further in March, reaching $7.5 trillion—matching ACH over the same period.

The market cap story is equally wild. DefiLlama data shows stablecoins have grown to a $316.7 billion market cap, setting a new all-time high.

For Q1 2026, the numbers get even more interesting. Stablecoins dominated crypto markets with 75% of total trading volume—the largest share on record. Overall transaction volume exceeded $28 trillion for the quarter, another all-time high.

Of course, not all of this is human-driven. CEX.IO reported that bots accounted for 76% of that volume, the highest proportion in the past two years.
