Stablecoin reserve growth could generate enough demand for U.S. Treasury bills to allow Washington to scale back long-dated bond issuance, in a shift that would tie the structure of the world’s largest sovereign debt market increasingly to the expansion of digital dollars.
In a note issued on Monday, Standard Chartered estimated that stablecoin market capitalization could reach $2 trillion by 2028, creating between $800 billion and $1 trillion of additional demand for T-bills as issuers invest reserves in short-term government debt.
Combined with expected Federal Reserve purchases, total new demand for bills could reach about $2.2 trillion over the period, exceeding projected supply if issuance patterns remain unchanged.
Excess Bill Demand Creates Scope To Cut Duration Supply
That imbalance would leave roughly $900 billion of excess demand for short-dated Treasuries, giving the U.S. Treasury a rationale to increase the share of bills in its funding mix.
Shifting that amount of issuance away from longer-dated securities could effectively allow the suspension of 30-year bond auctions for several years under the current schedule, according to the analysis.
Such a move would reduce duration supply at the long end of the curve and is likely to push long-term yields lower in the initial phase, producing a bull-flattening effect in the Treasury market.
Stablecoins Emerge As Structural Buyer Of Government Debt
The projected demand highlights how regulated stablecoins are evolving into a new, price-insensitive buyer of U.S. government securities.

Issuers typically hold reserves in short-term Treasuries to back dollar-pegged tokens, making the growth of digital payment infrastructure directly linked to sovereign funding conditions and front-end collateral availability.
This dynamic effectively turns stablecoins into a form of privately issued digital money that channels capital into government debt markets, reinforcing the role of the dollar in global liquidity systems.
Front-End Scarcity Risk And Policy Implications
If supply does not increase, the growing presence of stablecoin reserve managers alongside money-market funds and the Federal Reserve could make T-bills structurally scarce, tightening conditions in repo and short-term funding markets.
That creates a fiscal incentive for policymakers to accommodate stablecoin expansion within a regulated framework, as their growth would support demand for government financing while lowering pressure on long-term borrowing costs.
While Standard Chartered’s base case remains for higher long-term yields in the near term, the bank said the risk of a structural shift in issuance strategy will rise over the next several years as stablecoin adoption accelerates.
