The short version

  • Pressure stems from growing fiscal deficits, over $40 trillion in national debt, and heavy corporate bond issuance.[CNBC]
  • Official efforts by the U.S. Treasury Department and Secretary Scott Bessent to talk borrowing costs lower have not yielded results.[CNBC]
  • Major institutions are adjusting, with HSBC lifting its end-2026 10-year Treasury yield forecast to 4.65%.[CNBC]
