Term Premium Not Inflation Fears Explains 30-Year Treasury Yield Above 5%
The 30-year U.S. Treasury yield has held above 5% for the first ten trading days of July 2026, but the driver is an expanding term premium — now estimated at 110–140 basis points for the 30-year bond — rather than rising inflation expectations, which remain anchored at 2.20% on the 5-year, 5-year forward breakeven. Record fiscal borrowing of $671 billion projected for Q3 2026 is pressuring long-end yields as the Treasury holds coupon auction sizes flat, forcing the market to absorb greater duration supply at higher yields. Foreign demand is shifting in composition, with Japanese holdings at a record $1.21 trillion while Chinese holdings have fallen roughly 12% year-over-year, leaving private asset managers as the marginal buyer clearing auctions only at significantly elevated yields.
