Treasury yields near 4.6% open rare bond buying window

The 10-year Treasury yield near 4.6 percent is drawing fixed-income buyers who see rare value in long-dated government debt after a selloff that pushed the 30-year to its highest level since 2007.

"If there are cracks that show up in the financial system over the next few years, I've been expecting them to show up in Treasury debt," said Jon Hilsenrath, founder of Serpa Pinto Advisory and a veteran Federal Reserve watcher.

The buying case rests on a steep yield curve. The three-month bill yields about 3.8 percent, the 10-year sits near 4.62 percent, and the 30-year trades above 5 percent — a spread that rewards locking in longer maturities. Yields surged more than 50 basis points in May during fiscal stress and escalating tensions tied to the Iran conflict, pushing the 30-year to its highest level since 2007.

The opportunity carries risk. The Treasury Borrowing Advisory Committee, a panel of senior bond dealers that advises the Treasury on funding, warned in minutes released Aug. 5 that at current auction sizes the government faces a $1.45 trillion funding shortfall in fiscal 2027-28. Rising interest costs drove the biggest jump in Treasury outlays this year, up $120 billion, pushing total debt-service costs above $1 trillion annually — more than the United States spends on national defense.

A $1.45 Trillion Funding Gap

Treasury Secretary Scott Bessent has leaned on short-term bills to finance a roughly $2 trillion annual deficit, holding down reported borrowing costs while leaving the government more exposed to inflation and rising rates. He called the May yield spike "transient," linking it to energy-related shocks from the Iran conflict. The strategy echoes his predecessor, Janet Yellen, whom Bessent criticized in 2024 for "activist Treasury issuance" that flooded the market with bills to hold down long-term yields.

The collision ahead: Just as the Treasury is likely forced back toward longer-term bonds, the Federal Reserve under new Chair Kevin Warsh is moving to shrink its balance sheet. Dealers expect the Fed's holdings to drift toward shorter maturities and more bills, and a Warsh-appointed committee due to report in December will likely conclude the Fed is overstocked on long-term Treasuries. That would mean two waves of long-term supply converging with fewer buyers.

For most Americans, the abstraction lands in a concrete place: mortgage rates, benchmarked to Treasury yields, sit above 6 percent while much of the developed world pays closer to 4 percent. Hilsenrath calls Treasury debt "the collateral of last resort in the global financial system," the asset on which nearly everything else is priced. Foreign holders such as Japan and China have been slowly diversifying into gold rather than dumping bonds, which buys Washington time but keeps deferring the problem.

Oil prices also jumped, adding to the inflation pressure that underpins elevated long-end yields and complicating the case for locking in fixed income now. For investors, the window depends on whether Bessent's bet — that deregulation and fiscal discipline can tame the 10-year yield without direct intervention — holds as the Treasury and the Fed collide over long-term supply.
