Stablecoin Adoption Could Unlock $2 Trillion in New Treasury Demand

Stablecoins are becoming increasingly important in the U.S. government debt market. The link between stablecoins and Treasury bills is straightforward, but its significance has not yet been fully understood.

The GENIUS Act created a regulatory framework that allows payment stablecoins to be backed by highly liquid assets, including short-term U.S. Treasuries. As a result, issuers may need to buy more Treasury bills if stablecoin adoption accelerates.

An analysis from Brookings estimates that different growth scenarios for stablecoins could generate between $400 billion and $2.3 trillion of first-round net Treasury bill demand by 2030. This is large enough to attract attention in Washington, particularly as the U.S. government faces persistent deficits and growing pressure on the long end of the Treasury curve.

The relationship between stablecoins and Treasury bills is complex. Stablecoin issuers do not hold customer dollars in a vault; instead, they hold reserve assets such as cash, short-duration government securities, and Treasury-backed repo arrangements. The largest issuers already control reserve portfolios large enough to matter in short-term funding markets.

The global stablecoin market is approaching $300 billion, which is still small compared to the entire U.S. Treasury market. However, its importance is concentrated towards the short end of the curve, where new structural buyers can influence demand even without becoming dominant across the entire government bond market.
