US Core Inflation Surprise Adds Pressure to Global Bond Markets

A reportedly stronger-than-expected September US core CPI reading has renewed selling pressure across global bond markets, interrupting signs that the recent bond selloff was stabilizing.
Persistent underlying inflation can push investors to reassess the likelihood of additional Federal Reserve tightening and the timing of future rate reductions.
Higher expected interest rates generally pressure existing bond prices, particularly longer-duration securities, while increasing borrowing costs for governments and businesses.
The reaction highlights how sensitive global fixed-income markets remain to US inflation data. Sustained pressure will depend on subsequent economic releases and central bank guidance.
