U.S. Treasury to Buy Back Up to $6 Billion in Long-Term Bonds
The U.S. Treasury announced that it will buy back up to $6 billion in longer-term government bonds on Thursday, three times the usual single operation size of about $2 billion, targeting bonds issued with maturities of 10 to 20 years, aimed at supporting liquidity at the long end.
Treasury Secretary Scott Bessent stated on August 19 that such operations should at least be doubled to $4 billion, citing that liquidity at the long end is "very poor." The $6 billion is above the "at least $4 billion" lower limit but below some Wall Street expectations of $7 billion to $10 billion. The operation window is from 1:40 PM to 2:00 PM ET, with the targeted maturity dates ranging from February 2037 to August 2046, purchasing older off-the-run bonds rather than newly issued benchmark bonds.
After the announcement, the 10-year yield rose to about 4.85%, the highest since October 2023; the 20-year yield briefly exceeded 5.3%; and the 30-year yield stood at about 5.31%. On the same day, the Treasury also auctioned $39 billion in new 10-year bonds, with a winning yield of about 4.834%, one of the highest levels for newly issued bonds of that maturity in about 20 years. The total outstanding government debt is approximately $30 trillion to $32 trillion, with daily transactions exceeding $1 trillion. In August, the 30-year yield had risen to its highest level since 2007.
The buyback plan will extend until November 4, with the lower limit for remaining long-end operations still set at "not less than $4 billion." The Treasury's stance is to enhance long-end liquidity, allowing banks to offload hard-to-sell old bonds before participating in new bond auctions, rather than a Federal Reserve-style quantitative easing. Strategists from Wells Fargo and BNP noted that the market initially expected a larger single operation size. National debt exceeded $40 trillion in August.
Bessent attributed part of the long-end sell-off to the narrative that "the U.S. cannot pay its debts," stating it is detached from fundamentals. Buying back old bonds while continuing to issue new bonds means net supply has not disappeared. Rising oil prices and inflation expectations are simultaneously pressuring bonds.
In market mechanics, the sellers are primary dealers and banks looking to clear off-the-run inventories, while the buyers are the Treasury's cash account. The event-driven aspect comes from the buyback size being lower than expected, with funds continuing to demand a term premium at the long end. Beneficiaries are traders who can exchange old bonds for cash to bid on new bonds; those under pressure are funds leveraged long on government bonds, mortgage pricing, and corporate debt pricing. The $6 billion in a market with daily transactions of over $1 trillion is a liquidity adjustment, not a rewrite of the deficit path.
The yields on 10-year, 20-year, and 30-year U.S. Treasuries rose after the announcement; the subscription situation for the new 10-year auction will determine whether the short-term decline stops.

The U.S. Treasury restarted and regularized buybacks after 2000, originally intended to clean up old bonds and lubricate the secondary market. Bessent has turned it into a policy tool of "at least doubling" because long-end yields have already transmitted to mortgage and fiscal interest. The $6 billion against a $32 trillion stock is merely a spot removal of bonds: taking away hard-to-sell old bonds while auctioning $39 billion in new 10-year bonds on the same day. The market understood the arithmetic, hence yields rose instead of falling.
The capital path is that the Treasury uses cash to exchange for duration, while dealers use the freed-up balance to digest new supply. The motivation is evident in the auction: if long-end subscriptions worsen, the next issuance cost will be higher, and interest expenses will bite into the deficit. The strategy is to tie "liquidity support" and "yield suppression" in the same operation, but without the Fed's balance sheet expansion; cash is merely shifted from the Treasury to bondholders. Morgan Stanley and Jefferies had priced at $10 billion, indicating the market has already treated the buyback as a necessary expectation management.
Comparable examples include the UK's debt reduction buybacks in the 2010s, the Fed's reversal operations, and the Bank of Japan's yield curve control. The U.S. is in a phase of high deficits, high supply, and central banks not synchronously buying bonds, leading to rapid scale questioning of the Treasury's solo market-making. The high point of the 30-year yield around 2007 is being referenced again, indicating investors are pricing the fiscal path rather than a single buyback.
The structural judgment belongs to the unsuccessful transfer of pricing power amid regulatory changes. The mechanism is that long-end yields are determined by net supply, inflation, and term premium; buybacks can only change the floating supply of old bonds, not the flow of new bonds. Whoever can continuously absorb 10 to 30-year supply will hold the pricing power of U.S. Treasuries; if the Treasury only increases to $6 billion, the pricing power remains in the hands of global buyers demanding higher real rates.
