September’s hotter-than-expected CPI and the highest core inflation reading of the year suggest that underlying price pressures remain persistent, complicating the outlook for monetary easing. The sharp rise in October rate-hike expectations indicates markets are reassessing the likelihood of tighter policy, while the initial surge in five-year Treasury yields reflects increased concern over inflation and interest-rate risk. The subsequent bond rally suggests some reversal in positioning or demand for safety, although the underlying policy outlook remains uncertain.
