No, Scott Bessent's bond plan isn't motivated by national debt hitting $40 trillion, say top economists—but he has revealed what will make him flinch

Treasury Secretary Scott Bessent isn’t short of investors keen to rap his knuckles—and his friend and mentor, Stan Druckenmiller, was at the front of the queue.

Bessent has been chastised by many for his recent attempt to manage prices in the bond market. As 30-year Treasury yields rose toward a near-20-year high last month, the Treasury announced a multi-billion-dollar buyback scheme on long-dated Treasuries, which reduced supply and pushed yields down. With long-dated yields used as a benchmark for borrowing costs across the economy, conditions should have loosened (in theory) for everything from mortgage and government interest rates to business loans.

The timing seemed convenient to skeptics: The U.S. national debt just hit $40 trillion, with interest payments by the Treasury expected to exceed $2 trillion in the fiscal year 2026. Reducing the yield on bonds would bring down the government’s borrowing costs.

The action seemed all the more noteable as, just weeks before, Bessent announced an intervention to buy up the Japanese yen—the currency of the nation that holds the greatest value in American debt. One interpretation of the move was that it prevented Japan from selling its hoard of U.S. bonds to support its own currency—a move that would have raised yields on U.S. debt, making it more expensive for the government to repay.
