30-Year Treasury Yield Holds Above 5% for Longest Stretch Since 2006

The 30-year Treasury yield has spent more days above 5 percent this year than in any year since 2006.

The 30-year Treasury yield has closed above 5 percent on 55 trading days this year, the most since 2006, as a widening fiscal deficit, a record wave of corporate issuance and bets on a Federal Reserve rate hike keep long-end borrowing costs elevated. The yield touched 5.34 percent in mid-August, the highest since 2007 and within 10 basis points of a 22-year peak, before settling near 5.27 percent.

"Long-end yields are seen staying elevated until entitlement reform changes the deficit picture," said John Briggs, head of US rates strategy at Natixis North America. "Buybacks are a drop in the bucket."

Treasury Secretary Scott Bessent last month expanded buybacks of older bonds to contain long-end yields, yet investors doubt the purchases will offset supply. Companies are expected to sell about $215 billion of new debt in September after record issuance in August, while federal debt has surpassed $40 trillion. Traders price roughly a 70 percent chance the Fed raises rates by 17 basis points at its Sept. 15-16 meeting after Chair Kevin Warsh's hawkish Jackson Hole speech.

The stakes extend beyond the $31 trillion Treasury market. Sustained high long-end yields raise borrowing costs across mortgages, corporate credit and government refinancing, and pressure equity valuations. August employment data due Sept. 4 and inflation figures on Sept. 11 will shape whether the Fed acts, and options traders are already wagering the 30-year yield climbs toward 5.7 percent by Nov. 20.

Buybacks Face a Wall of Supply

The Treasury's expanded repurchase program, which raises the single-transaction cap on long-dated buybacks to at least $4 billion from Sept. 9, has done little to shift investor positioning. Bank of America rate strategists Meghan Swiber and Eleanor Xiao wrote Monday that "investors remain reluctant to add duration" despite the buybacks and other policy steps, with a shrinking official-sector bid leaving the market dependent on price-sensitive private demand.

Priya Misra, a portfolio manager at JPMorgan Asset Management, said the buybacks may support demand for the long bond but "may well be dwarfed by the onslaught of supply from the AI buildout." Tech giants including Alphabet, Amazon and Meta have issued nearly $220 billion in bonds since the start of 2026, far exceeding the roughly $108 billion sold in all of 2025, according to London Stock Exchange Group data. Morgan Stanley estimates global AI-related debt issuance could approach $570 billion this year.

Demand Structure Leaves the Long End Exposed

The 30-year bond occupies a niche in the Treasury market, with insurers and pension funds the main buyers as they match decades-long liabilities. Bond managers who prefer to limit interest-rate sensitivity tend to cap long-end exposure, a structural fragility that becomes more visible when yields climb.

Gregory Faranello, head of US rates trading and strategy at AmeriVet Securities, said "if you want to get the long end down, you tighten rates," and expects the Fed to raise rates while favoring 10-year and shorter tenors. After yields rose about 65 basis points from their 2026 low, Briggs said he has turned "more neutral" after being bearish on the long end all year, noting "you don't have to go up at a high speed forever."

Misra said the market "may be getting close to the peak in long-end yields, but there is uncertainty given all the cross currents at play." The last time the 30-year yield sustained levels above 5 percent for this long was in 2006, before the Fed's tightening cycle ended and the global financial crisis drove a flight to government debt.
