Stablecoin Demand Boosts US Treasury Bills but Fails to Solve Long-Term Debt Problems

Stablecoins are becoming increasingly important in the US government debt market, but their influence is concentrated in short-term Treasury securities rather than long-term bonds.

The recently introduced regulatory framework for payment stablecoins requires issuers to maintain reserves in highly liquid assets. These may include cash, bank deposits, overnight repurchase agreements and US Treasury securities with maturities of 93 days or less.

As a result, the growth of the stablecoin market could create additional demand for Treasury bills. However, the same rules do not directly support 10-year, 20-year or 30-year Treasury bonds.

Why Stablecoins Prefer Short-Term Treasury Bills

Stablecoins are designed to maintain a stable value against the US dollar. Users must be able to redeem their tokens quickly, which means issuers need reserves that can be converted into cash without significant losses.

Short-term Treasury bills are well suited for this purpose because they are highly liquid and generally considered low-risk assets. Longer-term bonds, on the other hand, are more sensitive to interest-rate movements and may lose value when yields rise.

This makes short-term government debt a more practical choice for stablecoin reserves.

The GENIUS Act Creates a Short-Duration Reserve Structure

Under the GENIUS Act, approved payment stablecoin issuers must maintain identifiable reserves equal to the value of their outstanding tokens.

Eligible reserve assets can include:

• US currency and Federal Reserve balances
• Withdrawable bank deposits
• Treasury securities with maturities of 93 days or less
• Qualifying overnight repo agreements
• Government money market funds holding approved short-term assets
• Other regulator-approved liquid federal assets

The reserve framework is centered on liquidity and capital preservation. A newly issued 10-year Treasury note or 30-year government bond does not qualify as a direct reserve asset under this structure.

USDC Reserves Show How the Market Works

Circle’s USDC reserve portfolio provides a useful example of how major stablecoin issuers manage their assets.

A large portion of the reserves is held in overnight Treasury repo, short-term Treasury securities and cash at regulated financial institutions. These assets allow Circle to meet redemption requests while limiting exposure to long-term interest-rate risk.

However, the growth of USDC does not necessarily mean that the entire increase represents new demand for US Treasury securities. Some users may move money from bank deposits or money market funds into stablecoins. In that case, the funds may simply change ownership rather than create entirely new demand.

Stablecoin Inflows Can Lower Treasury Bill Yields

Research suggests that strong stablecoin inflows can influence short-term Treasury yields. When stablecoin issuers buy more three-month Treasury bills, increased demand may push prices higher and yields lower.

The impact is much weaker in longer maturities. Investors in 10-year or 30-year bonds are more concerned with inflation, government borrowing, Federal Reserve policy and future interest rates than with stablecoin reserve demand.

This creates a clear maturity divide between the stablecoin market and the long-term Treasury market.

Treasury Buybacks Are a Separate Policy

The US Treasury has also expanded its plans to buy back older Treasury securities in the 10-year to 30-year maturity range.

These buybacks are intended to improve market liquidity by creating a more predictable exit for investors holding older, less actively traded bonds. However, the program is not the same as quantitative easing and does not represent direct stablecoin investment in long-term debt.

Treasury buybacks can improve trading conditions, but they do not eliminate the government’s broader borrowing needs.

What Does This Mean for Bitcoin?

Stablecoin growth may support Bitcoin indirectly by increasing dollar liquidity across crypto markets. More stablecoins can make trading and settlement easier on exchanges and decentralized finance platforms.

Still, there is no reliable evidence that stablecoin growth automatically causes Bitcoin prices to rise. Bitcoin is also influenced by interest rates, liquidity conditions, investor risk appetite, regulation and global economic developments.

The relationship is therefore indirect rather than mechanical.

Conclusion

Stablecoins could become an important source of demand for US Treasury bills and other short-term government debt. However, their reserve requirements do not directly create demand for long-term Treasury bonds.

The US government’s long-term borrowing challenge will continue to depend on traditional investors, global institutions, pension funds and financial markets willing to hold duration risk.
