10-Year Treasury Tops 5% in Mid-September Trading

A mix of persistent inflation, higher energy costs, large fiscal deficits as well as heavy corporate bond sales is renewing pressure on the Federal Reserve to raise rates.

Overview

  • The 10-year Treasury briefly rose above 5% in mid-September before easing slightly, a move driven by renewed buying and selling in the market.
  • Investors are pricing a greater chance of further Fed rate increases because August consumer inflation ran 3.4% year over year and oil has climbed after the Iran conflict.
  • Treasury Secretary Scott Bessent has expanded targeted buybacks to at least $4 billion and has publicly signaled active intervention, but those operations remain small relative to total issuance.
  • Big tech 'hyperscaler' borrowing for AI infrastructure is adding to supply pressure with roughly $250 billion of bond issuance expected in 2026 and forecasts of much more next year.
  • Higher long-term yields are already lifting mortgage and consumer loan rates, pressuring home affordability and lowering valuations on growth stocks by increasing the discount rate used to value future earnings.
