U.S. Treasury widens long-dated buybacks in bid to cool surging yields

BlockBeats reports that on Aug. 20 the U.S. Department of the Treasury unveiled an expansion of its long-term Treasury buyback program, a move closely watched by markets. On Wall Street, the decision is being read as an effort by Treasury Secretary Bentsen to relieve pressure on long-end yields and help contain the government's borrowing costs. The Treasury said that from Sept. 9 through Nov. 4 it will at least double the per-operation cap for repurchases of Treasuries maturing in 10 to 30 years, lifting the limit to $4 billion from $2 billion. Long-dated yields fell quickly after the announcement. The 30-year yield was down nearly 10 basis points at one point, and U.S. equities moved higher. While officials described the step as a technical adjustment aimed at improving market liquidity, many investors see the main objective as pushing back against a persistent climb in long-term yields. BNP Paribas estimates that, at the current pace, the Treasury could buy back about $128 billion a year of those maturities, roughly 30% of annual issuance in that bucket but only about 2.4% of total marketable debt outstanding. Jim Bianco, founder of Bianco Research, said the old market line "When the Fed panics, bond traders can stop panicking" may now need an update: "When Bessent panics, bond traders can stop panicking." The move comes as the 30-year Treasury yield recently topped 5.3%, its highest level in nearly two decades, while average mortgage rates have drifted back toward 7%. Federal debt has also surpassed $40 trillion, and the fiscal deficit remains around 6% of GDP, keeping concerns about debt sustainability elevated. Bessent, a former hedge fund manager, has leaned on less conventional market tactics since taking office, including tweaks to debt issuance policy, support for regulatory changes and involvement in foreign-exchange market interventions. Some market participants describe the approach as reflecting a distinctly hedge-fund-style macro trading mindset. Skeptics argue buybacks cannot resolve the structural drivers of rising debt and persistent deficits. Robin Brooks of the Brookings Institution said the step looks more like "manipulating the yield curve" than tackling the underlying fiscal problem. Investors are now watching whether more active Treasury intervention can keep yields contained for long, or whether it will merely offer short-term relief. Analysts say that without changes to fiscal spending and the trajectory of debt growth, buybacks alone are unlikely to shift the long-run direction of the Treasury market.
