Bessent defends bond buybacks as 30-year yield tops 5.2%

Treasury Secretary Scott Bessent defended the Trump administration's expanded bond buyback program Monday, pushing back on billionaire investor Stanley Druckenmiller's critique as the 30-year yield hovered near 5.26 percent.

"He changes his mind a lot," Bessent told CNBC, responding to Druckenmiller's Wall Street Journal op-ed that criticized the Treasury's active management of the long end of the curve. Bessent confirmed he has since spoken with his former mentor.

The 10-year yield rose 0.98 percent to 4.76 percent, while the 30-year yield climbed 0.92 percent to 5.26 percent, according to market data. Bessent cited flat yields, strong bond market performance, and Fitch's reaffirmation of the U.S. credit rating as evidence the intervention is working. Druckenmiller argued the government should let 30-year yields fluctuate freely to enforce fiscal discipline.

The public clash between a top administration official and one of Wall Street's most influential investors raises the stakes for the Treasury's yield-management strategy. If the intervention holds long-term yields down, it eases federal borrowing costs but risks distorting price discovery; if it fails, a spike in yields would ripple through mortgages, corporate credit, and equity valuations.

The expanded buyback program marks a more active role for the Treasury in its own debt market. Bessent has framed it as a liquidity tool that smooths trading in less-liquid maturities, while critics including Druckenmiller see it as de facto yield management that masks fiscal strain.

The 30-year yield at 5.26 percent remains elevated even with the intervention, a sign that investors still demand a sizable premium to hold long-dated U.S. debt. The 10-year at 4.76 percent has stayed relatively flat, which Bessent pointed to as proof of market confidence. Long-duration bond funds have felt the pressure, with the iShares 20+ Year Treasury ETF (TLT) down 0.63 percent to 82.36.

The 30-year yield above 5 percent is a level that raises the cost of long-dated borrowing across the economy, from mortgages to corporate debt. That makes the Treasury's intervention a high-stakes experiment: if it succeeds in anchoring yields, it could ease pressure on borrowers; if it fails, the market's verdict will be felt well beyond the federal balance sheet.

The Buyback Debate

Druckenmiller's critique argued that allowing 30-year yields to move freely would impose fiscal discipline on Washington. By intervening, he contended, the Treasury removes the market's natural check on deficit spending.

Bessent's response reflects a broader administration view that the bond market's signals are not always reliable guides for policy. The two men share a long history — Druckenmiller was Bessent's mentor early in his career, and their relationship has now become a public test of the administration's debt strategy.

The buyback program builds on the Treasury's existing framework for managing its debt portfolio, but the expanded scope shows a willingness to intervene more aggressively than in prior years. That shift has drawn scrutiny from investors who worry the Treasury is blurring the line between liquidity management and yield control.

What's at Stake

The dispute comes as the U.S. faces heavy debt issuance and persistent deficits. Fitch's reaffirmation of the U.S. credit rating provides some cushion, but the elevated 30-year yield suggests investors remain wary of the fiscal trajectory.

If the Treasury continues its intervention, it may keep a lid on long-term yields in the near term. But the risk is that markets eventually test the administration's resolve, forcing a choice between defending the program and letting yields find their own level. The outcome will shape federal borrowing costs and set a precedent for how aggressively the Treasury manages its own debt.

The dispute also lands as Bessent heads into G20 meetings, where U.S. debt management and fiscal policy are expected to draw scrutiny from global counterparts. The administration's intervention in its own bond market is an unusual step for a major economy, and the public disagreement with Druckenmiller gives critics a high-profile voice.
