Inflation is no longer just a gas-price problem
US consumer prices rose 3.7 percent in the year to September, above forecasts, and traders now see a real chance of another Fed rate hike. The debate is whether the energy shock from the Iran war is spreading into prices more broadly.
The September consumer price index came in hotter than expected weeks before the midterm elections. Economists agree energy is the main driver, but they disagree on how far the pressure has spread.
Key claims
- Gasoline drove most of September's increase.
- Price pressures are broadening beyond energy into core goods and services.
- The Fed may now raise rates again in October or December.
- Prices are rising faster than paychecks.
What the evidence says so far
The Bureau of Labor Statistics reports that the all items index rose 0.6 percent in September and 3.7 percent over 12 months, up from 3.4 percent in August. Gasoline rose 9.1 percent in the month and accounted for over half of the monthly increase. The index excluding food and energy rose 0.3 percent in the month and 2.6 percent over the year. Shelter, recreation, used cars, education, airline fares, medical care and apparel all rose.
On the broadening claim, the evidence cuts both ways. Moody's Mark Zandi, quoted by CNBC, said "the war's fingerprints are all over the report." RBC's Michael Reid called inflation an "oil story" but said tariffs are adding to it. RBC also noted record monthly increases for toys and other recreational goods, which are largely imported. Other analysts quoted by CNBC said pressures are broadening beyond energy.
CNBC reports that, per the CME FedWatch tool, the odds of a quarter-point hike at the Oct 28 meeting rose from 22.1 percent to 53.7 percent after the report, with more than a 95 percent chance of at least one hike by year end. These are market probabilities that change daily and are not forecasts by the Fed.
The wage claim comes from an eToro analyst quoted by CNBC and was not checked against official wage data.
