Recent inflation readings, including September CPI rising 0.6% month-over-month to 3.7% year-over-year with core pressures at 2.6%, combined with the Federal Reserve’s September 25-basis-point hike to a 3.75–4.00% fed funds target, have lifted 10-year Treasury yields above 5% and tempered equity valuations. The S&P 500 has traded near 7,600–7,800 amid this environment, supported by robust Q3 earnings growth driven by AI-related capex and resilient corporate profits, yet pressured by narrower breadth and a cooling labor market. Traders are monitoring the late-October FOMC decision, Q3 GDP release, and core PCE data for signals on the rate path, with market-implied odds reflecting ongoing uncertainty around further tightening.
