FRB Governor Says Stablecoins Support Dollar Supremacy

Federal Reserve Governor Christopher Waller said the dollar's supremacy in the global financial system isn't going away, but the technology underlying how it moves around the world is changing fast.

At the Fed's annual Conference on the International Roles of the U.S. Dollar, Mr. Waller said the traditional pillars of dollar dominance - the depth of U.S. financial markets, institutional trust, and rule of law - remain intact. He said that distributed ledger technologies and tokenized assets like stablecoins are creating entirely new channels for global dollar intermediation. These innovations are operating alongside, and increasingly in competition with, traditional banking and payment infrastructure.

Mr. Waller said policymakers are now studying stablecoin-driven shifts in foreign exchange markets, how stablecoin capital flows may influence exchange rates and cross-border lending conditions, and whether dollar-backed stablecoins could create a novel pipeline connecting global liquidity demand directly to U.S. Treasury markets. He warned that if stablecoin adoption continues to scale, the demand dynamics for U.S. safe assets could shift in ways that are not fully captured by traditional models.

Mr. Waller said that regulators are paying close attention to both the opportunities and the risks digital assets present. He framed private-sector innovation in stablecoins and blockchain payments as a positive competitive force, but that research suggests open questions remain about systemic spillovers, monetary policy transmission, and whether stablecoins ultimately reinforce or strain the dollar's global role.
