Wall Street banks expect roughly $1 trillion of net Treasury bill issuance over the next year, according to the Financial Times. Bank of America projects about $1.07 trillion, JPMorgan $1.09 trillion and Goldman Sachs roughly $961 billion.
Those are bank forecasts, not an announced $1 trillion Treasury plan. But the direction fits the government’s current funding needs. The Treasury officially expects $739 billion of net marketable borrowing in July–September and another $628 billion in October–December, while saying bill auction sizes may increase again in October.
Why Borrow Short-Term?
The reason is increasingly visible in the bond market.
Long-term Treasury yields have climbed to levels not seen in nearly two decades, with the 30-year rate recently reaching about 5.35%. That has already increased financing pressure across stocks, mortgages and corporate debt, while an expanded $6 billion Treasury buyback failed to bring long-term yields meaningfully lower.
Treasury bills mature within a year. Issuing more of them lets the government avoid locking in today's elevated long-term borrowing costs for decades.
But that does not make the debt cheaper forever.
The Trade-Off Is Rollover Risk
Short-term borrowing has to be refinanced frequently.
If interest rates remain high, or rise further, the government must repeatedly replace maturing bills at expensive new rates. That creates rollover risk, effectively exchanging today's long-duration problem for greater exposure to tomorrow's interest rates.
The shift also comes with federal debt already above $40 trillion, while heavy issuance itself is one reason Treasury yields have been climbing.
There is, however, plenty of natural demand for bills.
Money-market funds hold enormous amounts of short-term government debt, while stablecoin issuers also use Treasury bills as reserve assets. Higher short-term yields can therefore increase the income earned behind products such as USDC and USDT, as seen in the economics of stablecoin Treasury reserves.
