US debt puts Treasury yields beyond Bessent’s reach for now

Treasury yields ended the week at 4.73%, near Bessent-era highs, after his buyback plan briefly lowered borrowing costs.

Treasury Secretary Scott Bessent said Thursday the government would repurchase long-dated debt while issuing more short-term securities to fund the move. He described the approach as a "Treasury twist," borrowing a phrase associated with earlier efforts to alter the shape of the yield curve.

A twist loses traction

The market reaction lasted less than two trading days. Long-bond yields fell after the announcement on Wednesday, then climbed back as investors reassessed the scale of the plan against the supply of debt they still need to absorb.

The 10-year Treasury yield closed the week at 4.73%, close to its highest level since Bessent took office. The benchmark matters because it helps set borrowing costs across mortgages, corporate debt and federal financing.

Bessent has argued that Treasury yields are not aligned with equilibrium levels, a claim that puts the department in the unusual position of trying to influence pricing in the world’s main government bond market. Some investors disagree with that premise.

Edward Yardeni, the market strategist known for coining the term bond vigilantes, said rates in the current range do not look abnormal by historical standards. "I think we are back to normal interest rates, 4% to 5% is normal," Yardeni said before Bessent’s announcement.

Debt and AI supply collide

The Treasury plan lands in a market already dealing with heavy borrowing needs. One US debt gauge cited in the market discussion topped $40 trillion this week, adding to concerns that investors will demand more compensation to hold longer maturities.

Corporate borrowers are also competing for long-term money. Artificial intelligence investment has helped drive issuance from large technology companies, including Alphabet Inc., which sold bonds earlier this month with maturities extending as far as 40 years.

That supply matters for Bessent’s strategy because buyers of long-duration assets can choose between Treasuries and high-grade corporate debt. If companies keep issuing heavily, Treasury buybacks may shift the composition of government supply without removing the broader demand for long-term funding.

Matt King, founder of Satori Insights, said the paths to lower long-end yields all involve outcomes the administration may not welcome. "Every route to lasting relief for the long end runs through something the administration doesn’t want," King said, citing a smaller deficit, weaker equities or a pullback in AI investment.

Liquidity claim meets skepticism

The Treasury has framed the buyback plan partly as a liquidity tool. JPMorgan Chase & Co.’s rates strategy desk reported Thursday that "market functioning has improved notably this year," a view that complicates the case for intervention on trading conditions alone.

The broader question is whether the Treasury can move long rates by changing issuance patterns while investors focus on deficits, inflation and Federal Reserve policy. Market participants have also cited uncertainty over Chairman Kevin Warsh’s policy approach as part of the backdrop for higher term premiums.

Three paths for long rates

If federal borrowing remains elevated and AI-related issuance continues, global investors may keep demanding higher returns on longer debt. In that scenario, Treasury’s buyback program would have limited power, while corporate borrowers face higher refinancing costs across technology and other capital-intensive sectors.

If the deficit path narrows or AI spending cools, the pressure on long-duration bond demand could ease. That would help the Treasury finance debt at lower rates, but it would also signal slower investment momentum for companies that have been expanding data-center and computing capacity.

If inflation or Fed-policy uncertainty rises instead, global bond markets could reprice around a higher long-run rate structure. The main open question is whether Bessent’s issuance shift can matter enough to offset those forces once investors move beyond the initial announcement.
