U.S. Treasury Secretary Scott Bessent announced Wednesday that the government will at least double its long-term bond buybacks to address surging yields, but the intervention provided only temporary relief as borrowing costs resumed their climb.**
On August 19, the Treasury said it would increase buybacks of 10-, 20-, and 30-year bonds from $2 billion to at least $4 billion per operation, effective September 9 through November 4. The move followed a sharp rise in long-term Treasury yields, with the 30-year yield peaking at 5.34% on August 18, its highest level since 2007. The 10-year yield also climbed to 4.73% amid broader concerns over inflation and fiscal policy.
The intervention’s limited impact underscored deep market skepticism. While yields initially dipped after the announcement—dropping the 30-year to 5.18% and the 10-year to 4.63%—they reversed course by Thursday, with the 30-year yield rising back to 5.27% and the 10-year to 4.73%. Analysts cited multiple factors beyond the Treasury’s control, including inflation expectations, Federal Reserve policy shifts, and corporate debt issuance, as contributing to the selloff.
Treasury officials defended the strategy as a liquidity measure, not a yield-control tactic. Bessent told CNBC on August 20 that the Treasury has a “big toolkit” and that yields had “gotten a little ahead of themselves.” He suggested that inflation concerns would ease once geopolitical tensions, such as the U.S.-Iran conflict, subsided. The Treasury also hinted at future deficit-reduction plans, though no specifics were provided.
The national debt’s milestone added urgency to the intervention. On the same day as the buyback announcement, the U.S. debt surpassed $40 trillion for the first time, raising questions about the sustainability of borrowing costs. Roughly $10 trillion in debt maturing within 12 months faces refinancing at rates 300 to 400 basis points higher than in 2020, increasing the government’s interest burden.
Market reactions extended beyond bonds. The U.S. dollar weakened, with the DXY index falling to 98.6630, while gold and Bitcoin gained as investors sought alternatives amid concerns over currency debasement. The 30-year breakeven inflation rate—a measure of inflation expectations—also rose to 2.34%, its highest since June, signaling growing unease over price stability.
Critics dismissed the buybacks as a temporary fix. BNP strategists argued that the measures would struggle to offset “declining Fed credibility or rising rate expectations,” while CFRA Research’s Arun Sundaram called the intervention a “band-aid” for deeper economic issues. Some analysts suggested the Treasury’s actions could complicate the Federal Reserve’s monetary policy, as the Fed and Treasury appeared to be working at cross purposes.
The episode highlighted broader debates over fiscal policy and market intervention. Supporters of the Treasury’s move framed it as a necessary step to stabilize volatile markets, while skeptics warned that without addressing the root causes of debt and inflation, such interventions would only provide short-term relief. The failure to sustain lower yields reinforced concerns that the U.S. may be entering a “doom loop,” where rising interest payments force further borrowing, exacerbating fiscal pressures.
