Recent August CPI data showing a 0.4% headline monthly rise and 0.3% core increase, both exceeding core forecasts amid gasoline prices surging nearly 4% due to elevated oil above $100 per barrel from Middle East tensions, have lifted trader focus on September's monthly print. Rising one-year consumer inflation expectations to 4.6% and the upcoming September FOMC meeting, where markets price an 85% chance of a 25 basis point rate hike, reinforce concerns over persistent pressures above the Fed's 2% target. With outcomes clustered between 0.4% and 0.6% monthly, sentiment reflects uncertainty over energy spillovers versus potential moderation in shelter and goods components.
