AI Summary
Summary: CPI Meets Expectations Amid Wide Wholesale-Retail Inflation Gap
Key Inflation Data:
The August Consumer Price Index (CPI) aligned with forecasts, showing month-over-month growth of +0.4% (up from +0.1% in July) and core CPI at +0.3% (versus +0.2% in July). Year-over-year inflation held steady at +3.4% for the second consecutive month, while core inflation improved to +2.4%, marking 2024 lows. This represents a significant cooldown from the May peak of +4.2%.
Wholesale vs. Retail Divergence:
A notable discrepancy emerged between wholesale and retail inflation. The Producer Price Index (PPI) released yesterday showed headline growth of +5.4% and core at +4.8%, creating an extraordinary 200-240 basis point gap with CPI figures. This suggests retailers are absorbing substantial inflation costs rather than passing them to consumers, raising sustainability concerns.
Federal Reserve Implications:
The inflation data has increased odds of an interest rate hike at next week's FOMC meeting to 88%. A 25-basis-point increase would push the Fed funds rate to 3.75-4.00%, the highest since early December. However, uncertainty surrounds new Fed Chair Kevin Warsh's approach, particularly given President Trump's preference for lower rates.
Market Response:
Bond yields initially spiked—the 10-year reaching 4.97% (October 2023 levels) and the 30-year touching 5.36%—before retreating slightly. Pre-market futures rallied after four consecutive down sessions. Oil prices dropped 3% to $99/bbl (WTI) and $104 (Brent), though remain up 7.5% week-over-week amid Middle East tensions.
