Stablecoins crossed a critical threshold as on-chain transfer volume reached $33 trillion in 2025, surpassing the combined totals of Visa and Mastercard. By June 2026, monthly volume hit a record $1.79 trillion, up 125% year-over-year, reinforcing that dollar-pegged crypto assets have become genuine financial infrastructure rather than a trading sideshow.
The US has already legitimized payment stablecoins through the GENIUS Act, signed in July 2025. Industry surveys now show 13% of financial institutions use stablecoins and 65% plan adoption within 6–12 months. The market has bifurcated: Tether’s USDT leads real-world payments with $95 billion in identified commercial payments in H1 2026 and an all-time high supply of $188 billion, while Circle’s USDC dominates DeFi and institutional flows after processing $8.3 trillion in transfers in January 2026 alone.
The deposit threat is becoming a central banking concern. Standard Chartered estimates stablecoins could drain roughly $500 billion from U.S. banks by the end of 2028, and a Federal Reserve analysis suggests every $100 billion in net deposit drain could reduce bank lending by $60–126 billion. JPMorgan, Bank of America, Citigroup, and Wells Fargo are reportedly building a shared tokenized deposit network via The Clearing House with a planned H1 2027 launch.
Meanwhile, the European Central Bank and EU national central banks are pushing back against MiCA’s current reserve rules. Under existing MiCA, significant e-money token issuers must hold at least 60% of reserves in bank deposits, and ordinary issuers 30%. The ECB warns these deposits can exit rapidly during redemptions, assigning electronic money institution deposits a 100% outflow rate in liquidity stress assumptions. Instead, it wants minimum reserves held in assets maturing within one to five working days. The euro stablecoin market remains small at about €450 million in January 2026, but the ECB’s concern is forward-looking.
The ECB's consultation response, submitted to the European Commission ahead of the September 30 deadline, does not change MiCA yet. But it frames a broader question: whether stablecoin reserve design can protect token holders and avoid bond fire sales without turning stablecoin reserves into flight-prone bank funding.
