The U.S. 30-year Treasury yield climbed above 5.5%, marking its highest level since 2004. This milestone in long-term borrowing costs coincides with updated economic data showing persistent inflation expectations and shifting consumer sentiment. Final September one-year inflation expectations held steady at 4.6%, unchanged from the prior reading. Meanwhile, the University of Michigan consumer sentiment index rose to 48.1, beating forecasts of 47.6 and improving from the previous 47.8 reading.
