Fed’s Barr Backs Clear Stablecoin Rules but Warns of Run Risks

The United States signed the GENIUS Act into law on July 18, 2025, establishing the first federal framework for payment stablecoins. It requires issuers to maintain 1:1 reserves in eligible assets such as U.S. dollars and short-term U.S. Treasury securities. Stablecoins are now used primarily for crypto trading and holding dollars offshore, but their safety could have broader implications for the financial system if their use expands into remittances, trade finance and corporate treasury management.

Speaking at a Federalist Society event on March 31, 2026, Federal Reserve Governor and former Vice Chair for Supervision Michael Barr said regulatory clarity could accelerate market development. However, he warned that inadequate identity checks in secondary markets, issuers’ pursuit of yield and weak reserve liquidity could still enable money laundering and trigger runs. The law is scheduled to take effect either 18 months after its signing or 120 days after regulators issue final rules, whichever comes first.
