Recent hotter-than-expected September CPI data, showing headline inflation at 3.7% year-over-year and core at 2.6%, have shifted trader focus toward additional Federal Reserve tightening after the September 25-basis-point hike to a 3.75–4.00% target range. This has lifted 10-year Treasury yields near 5.3% and supported the DXY around 101.6–102.2, with October highs above 102.5. Market-implied odds now price a meaningful chance of further rate increases by year-end, contrasting earlier pause expectations. The late-October FOMC meeting and upcoming PCE release remain key catalysts that could reinforce or ease dollar strength depending on incoming inflation and labor data.
