Treasury Secretary Scott Bessent's bond market interventions have trimmed longer-dated yields from their 16-year highs, but Wall Street skepticism is deepening. The core problem: the Treasury issued $4.8 trillion in debt in 2025 alone, and analysts question whether the department has sufficient firepower to manage a market that continues to demand higher yields.

Bessent proposed doubling the Treasury's buyback program for off-the-run securities—expanding from the usual $2 billion in purchases initiated under Janet Yellen two years ago. Treasury sources this week signaled the department could also tap its $935 billion general account for fixed-income purchases.

Stanley Druckenmiller, head of Duquesne Family Office and a mentor to Bessent, directly challenged the strategy. In a Wall Street Journal op-ed, Druckenmiller argued that a 30-year Treasury yield of 5.5 percent is not a crisis but an "invoice"—the market's price for government debt.

"Every basis point of artificial yield suppression is a subsidy to procrastination," Druckenmiller wrote, urging Bessent to abandon the buyback program announced Aug. 19. He warned that once markets perceive the Treasury is defending a specific price, any yield rise becomes a test of official resolve, forcing increasingly larger interventions.

"Governments defending prices against fundamentals always lose. The only variable is how much they spend before conceding," he said.

The underlying tension is fiscal. U.S. debt has topped $40 trillion, and the 2026 budget deficit is on track to exceed $2 trillion. Without addressing the primary deficit, Druckenmiller contended, yield-tamping efforts corrode the Treasury's credibility and market confidence in U.S. creditworthiness.

Market analysts broadly agree that buyback operations alone cannot contain yields in a structural deficit environment. The 10-year and 30-year have anchored higher on the perception that rate-cut cycles are exhausted and fiscal deficits will require sustained government borrowing at elevated real rates.

The Treasury Department did not immediately comment.
