Treasury doubles long-term buybacks to $4 billion, yields slide

The Treasury's move to at least double long-dated buybacks to $4 billion per operation injects fresh liquidity as U.S. debt nears $40 trillion.

The Treasury will at least double long-dated bond buybacks to $4 billion per operation, pulling the 30-year yield down 9 basis points to 5.19% as investors read fresh liquidity support for the long end.

"The repurchase expansion is not a debt paydown but a rearrangement of the maturity schedule, with the supply likely replaced by more issuance on the short end, particularly bills," said Peter Boockvar, chief investment officer at One Point BFG Wealth Partners.

The 10-year yield lost 6 basis points to 4.647%, while the 30-year had touched a high above 5.33% earlier this week, the highest since 2007. The move comes as long-dated yields globally have been heavily sold, with elevated oil prices and inflation fears keeping term premiums elevated across developed markets — Japan's 10-year yield reached its highest in three decades, Germany's 30-year bunds hit their highest since 2011, and France's 30-year touched levels not seen since 2008.

The buyback expansion lands as the U.S. national debt is set to surpass $40 trillion this week, months earlier than forecast, with the fiscal deficit jumping to $432.3 billion in July — the highest monthly total since March 2021 — pushing the year-to-date shortfall to nearly $1.8 trillion. Interest on the debt has cost the government about $1.2 trillion this year.

The new cap, effective Sept. 9, applies to liquidity support repurchases of long-dated nominal coupon bonds, a program the Treasury uses to smooth the maturity profile of its outstanding debt. Doubling the per-operation ceiling to at least $4 billion gives the department more room to buy back longer-dated securities as issuance concentrates at the front of the curve.

The announcement offered a reprieve to a long end that had been under sustained selling. The 30-year yield had surged this week to levels not seen since 2007, and traders were bracing for a $16 billion auction of new 20-year bonds. The buyback news helped long-dated Treasuries extend gains, with the 30-year yield falling as much as 9 basis points.

Debt Load Nears $40 Trillion as Deficits Widen

The fiscal backdrop explains why the Treasury is leaning on buybacks rather than outright paydowns. Faster borrowing, driven in part by billions of dollars in lost revenue from invalidated tariffs, means the national debt is likely to cross $40 trillion this week — months earlier than forecasters previously expected. The July deficit of $432.3 billion was the largest monthly shortfall since March 2021, and interest payments on the debt have consumed roughly $1.2 trillion this year.

The buyback program does not reduce the overall debt burden; it reshapes the maturity schedule. By repurchasing longer-dated bonds and funding the operations with shorter-dated issuance, the Treasury can ease the strain on the long end where term premium concerns have been most acute. That dynamic is what investors read as supportive for long-duration holders.

Global Yields Under Strain

The U.S. move comes against a backdrop of rising long-dated yields worldwide. Japan's 10-year yield reached its highest level in three decades, Germany's 30-year bunds hit their highest since 2011, and France's 30-year touched levels not seen since 2008. Elevated oil prices and fears that inflation could accelerate have kept term premiums elevated across developed markets.

Investors will also parse the Federal Open Market Committee minutes due for release this afternoon, with attention on the sharp divisions within the central bank. At the July meeting, three officials dissented in favor of hiking rates, and the minutes may shed light on how close the committee came to tightening. The buyback announcement and the FOMC minutes together will shape the near-term path for long-dated yields as the Treasury continues to manage a record debt load.
