Treasury Buyback Fails to Cool Long-Term Yields

The U.S. Treasury’s decision to triple its long-dated bond buyback failed to ease investor concerns over rising government debt, persistent deficits and elevated Treasury yields.

The Treasury said it would repurchase up to $6 billion of debt maturing in 10 to 20 years, compared with a previous $2 billion ceiling. The increase exceeded the $4 billion minimum Treasury Secretary Scott Bessent outlined last month as part of efforts to improve liquidity in longer-dated securities.

Still, investors had expected a stronger intervention, with some market participants anticipating purchases of up to $10 billion.

Following the announcement, the benchmark 10-year Treasury yield climbed to its highest level since November 2023. The 20-year yield reached a three-week high, while the 30-year yield also advanced. Yields extended gains Thursday after August producer inflation rose and oil prices moved above $100 per barrel.

Padhraic Garvey, head of global rates and debt strategy at ING, said markets had expected Treasury to make a bigger statement, describing the $6 billion purchase as potentially an “opening gambit.”

Analysts said the reaction highlights the limited ability of Treasury buybacks to control borrowing costs. While repurchases can improve liquidity in older bonds and provide some support to long-term Treasury prices, $6 billion remains small compared with the roughly $32 trillion Treasury market.

Concerns are being amplified by U.S. government debt recently surpassing $40 trillion and large fiscal deficits. Jim Barnes, director of fixed income at Bryn Mawr Trust, said Treasury’s proactive attempt to contain long-term yields could itself signal that market strains are becoming more serious.

Investors are increasingly viewing buybacks not only as a liquidity-management tool but also as a possible way to reduce supply pressure in longer-dated bonds.

However, analysts remain skeptical that repurchases can overcome the fundamental forces driving yields higher. Tony Miano of Wells Fargo Investment Institute said widening federal deficits, persistent inflation and increased global bond issuance are among the pressures that Treasury buybacks are unlikely to materially change.
