The U.S. Treasury Department will expand its long-term bond buyback program after a sharp rise in borrowing costs pushed the 30-year Treasury yield to its highest level since 2007. The move is intended to improve liquidity in longer-dated government debt, support orderly market functioning and ease pressure in less actively traded Treasury securities.
Starting September 9, 2026, the Treasury will at least double the maximum size of buyback operations for nominal coupon securities in the 10- to 20-year and 20- to 30-year maturity ranges. The maximum amount per operation will rise from $2 billion to at least $4 billion, with the new limits remaining in effect through November 4, the end of the current quarterly refunding period.
Treasury Buyback Program Explained
A Treasury buyback occurs when the government repurchases previously issued bonds from investors. These operations do not reduce the government’s overall debt burden. Instead, they are designed to improve secondary-market liquidity, especially for older “off-the-run” securities that can trade less actively than newly issued bonds.
The Treasury said the larger operations reflect consistently strong participation from market participants and a substantial volume of high-quality offers in long-dated maturity segments. By purchasing a greater amount of these securities, officials aim to provide targeted liquidity support where demand has been most persistent.
The Treasury will release an updated buyback schedule separately. Under the current plan, the next 10- to 20-year operation is scheduled for September 10, followed by a 20- to 30-year operation on September 24.
Long-Term Treasury Yields Decline
The announcement came after the 30-year U.S. Treasury yield climbed above 5.3% earlier in the week, a level not seen in nearly two decades. Investors have become increasingly concerned about large fiscal deficits, substantial debt issuance and inflation risks that could keep interest rates higher for longer.
Longer-term Treasury yields declined after the policy update. The 30-year yield fell by close to 10 basis points to around 5.19%, while the benchmark 10-year yield also moved lower. Bond prices rise when yields decline, meaning the buyback plan gave immediate support to long-duration government bonds.
Impact on Stocks and Markets
Lower Treasury yields can be supportive for equities because they reduce discount rates used to value future corporate earnings. Growth-oriented stocks, including technology and semiconductor companies, are particularly sensitive to moves in long-term yields because much of their valuation depends on projected profits many years ahead.

Equity futures rose after the Treasury announcement as investors welcomed the decline in borrowing costs. However, the policy does not alter regular Treasury auction sizes or net debt issuance in the near term. Its purpose is liquidity support—not monetary stimulus or a broad effort to control interest rates.
Outlook for Bond Investors
The Treasury’s buyback expansion may help stabilise trading conditions for longer-dated debt, but it does not eliminate the underlying forces driving yields higher. Fiscal policy, inflation data, Federal Reserve decisions and investor demand for U.S. debt will remain the central drivers of the Treasury market.

Investors will watch the September buyback operations closely for their effect on liquidity, long-term yields and risk assets. The next quarterly refunding announcement on November 4 is expected to provide further guidance on the future size of Treasury buybacks.
