The 30-year Treasury yield has climbed to roughly 5.23% to 5.34%, its highest since 2007, while the 10-year yield sits near 4.79% to 4.80%. Persistent inflation, Middle East tensions, and heavy AI-related corporate borrowing are pushing US government debt costs to a two-decade peak.
The US government now pays more to borrow than it has in almost twenty years. The 30-year Treasury yield has climbed to roughly 5.23% to 5.34%, a level the bond market hasn't seen since 2007, while the 10-year yield has pushed to around 4.79% to 4.80%.
Inflation, oil, and AI debt push yields higher
Inflation remains stubbornly elevated, with recent readings landing between 3.4% and 4.1%, well above the Federal Reserve's 2% target. That gap keeps bond investors demanding higher yields as compensation. Renewed tensions in the Middle East have also pushed oil prices higher, feeding directly into inflation expectations.
A less obvious driver is the volume of corporate borrowing tied to artificial intelligence infrastructure. Companies worldwide have issued hundreds of billions of dollars in debt to fund AI buildouts in 2026, and that issuance competes with government bonds for investor dollars. As a result, the Treasury has to offer more attractive yields to find buyers.
Fed holds steady as hike odds build
Federal Reserve Chair Kevin Warsh has held the policy rate steady between 3.5% and 3.75% across several consecutive meetings. However, markets are now pricing in a 60% to 65% probability of a rate hike at the Fed's upcoming September 16 meeting.
Debt costs and mortgage rates climb
The US national debt now exceeds $40 trillion, and every basis point increase in yields adds billions of dollars in annual interest payments. The Treasury has tried to ease the pressure through expanded bond buyback programs meant to support market liquidity, but those efforts haven't been enough to meaningfully bend the yield curve back down.
Bond yields in Japan, the UK, and Germany have also pushed to new highs, since global capital markets are interconnected and a repricing in the world's benchmark borrower tends to cascade. For everyday Americans, the impact shows up fastest in mortgage rates: with the 10-year yield near 4.8%, 30-year fixed mortgage rates sit at levels that have meaningfully cooled housing activity.
