Uncle Sam Buys More of His Own Debt

The US Treasury Department made a surprise move on Wednesday, announcing that it will step up purchases of long-term government bonds to support a stressed corner of the market. This move is significant, not just because of the amount involved, but also because of the timing.

The Treasury Department’s decision to increase its long-term buyback cap from $2 billion to at least $4 billion, starting from September 9, is a departure from its normal quarterly financing plan. This change comes just two weeks after the Treasury Department laid out its plan and left the long-term buyback cap unchanged.

The bond market responded quickly to the news, with the 30-year Treasury yield (^TYX) dropping to 5.19% on Wednesday, its biggest one-day drop in 10 months. However, the yield rebounded sharply early Thursday. The dollar index (DX-Y.NYB) also fell 0.75% on Wednesday, its biggest drop since April 30, and was little changed on Thursday.

The Treasury Department’s move is aimed at supporting the long-term bond market, which has been facing stress due to high inflation, heavy government and corporate borrowing, and doubts about where Fed policy goes next. The program is not new, but it has been gradually expanded since its launch in 2024. The Treasury Department buys older bonds that are harder to trade, freeing dealers to keep more bonds moving through the market.

This move puts Treasury Secretary Scott Bessent in an interesting position opposite Fed Chairman Kevin Warsh. Warsh has been advocating for a hands-off approach, allowing markets to speak for themselves. However, Bessent’s decision to step in and support the long-term bond market may be a sign that the Treasury Department is taking a more active role in managing the market.

The bigger story, however, is what comes next. The Treasury Borrowing Advisory Committee, which advises the Treasury Department on how to finance the US government, has said that current borrowing plans should work through fiscal 2026. However, dealer forecasts imply a nearly $1.5 trillion financing shortfall across fiscal 2027 and 2028 if the Treasury Department continues to borrow in the same way. As a result, dealers expect larger bond auctions beginning in 2027, which will mean more Treasury supply hitting the market.

The Treasury Department’s move is an attempt to make the market easier to navigate. However, it cannot remove the underlying reasons for higher long-term yields, such as inflation, heavy government and corporate borrowing, or doubts about where Fed policy goes next. That remains the responsibility of the Fed, particularly after financial conditions recently loosened even as long-term rates climbed.

Ultimately, the Treasury Department’s move is a sign that it is trying to make the pipes bigger before the load gets heavier. Wall Street is being asked to carry more of America’s debt, and the Treasury Department is trying to make it easier for them to do so.

The Bond Market’s Reaction
