NEW YORK — September consumer price inflation came in above market expectations, prompting a wave of analysis suggesting that inflation above 2% has effectively become entrenched in the United States. Prices are rising not only for energy, which is affected by the war in the Middle East, but across other services and goods as well, making the broad advance a key source of upward pressure on market interest rates.
In its October Beige Book released on the 14th, the Federal Reserve said prices rose "in all Districts as the effects of higher oil prices came through," adding that "businesses reported that higher costs from elevated diesel prices and fuel surcharges were being passed along throughout supply chains." The report also said business contacts in several districts noted continued price pressure from other raw material costs, tariffs and insurance premiums.
The Fed's concerns align with the September CPI data released the previous day. According to the Bureau of Labor Statistics, the consumer price index rose 3.7% from a year earlier and 0.6% from the previous month, exceeding the 3.6% and 0.5% forecasts compiled by Dow Jones. Core CPI, which excludes volatile energy and food prices, rose 2.6% year-on-year and 0.3% from August, each 0.1 percentage point above market expectations. Services CPI, which includes housing, medical care, education, telecommunications and urban transportation, rose 3.1% from a year earlier and 0.4% from the previous month.
Unlike oil prices, which have been climbing but have been described as a short-term factor tied to the war, the increases in housing and service costs point to the possibility that high inflation is spreading broadly and will persist.
Austan Goolsbee, president of the Federal Reserve Bank of Chicago, expressed deep disappointment with the CPI figures in a Yahoo Finance interview the same day, saying that services inflation running above 5% is not the result of tariffs or higher oil prices.
The breadth of the U.S. price increases is attributed to the cumulative effects of tariffs and higher global oil prices now being passed through to consumers in earnest. Raw material shortages and rising input costs driven by the artificial intelligence investment boom are also rippling through industry. Consumer demand that has not fallen sharply, supported by relatively stable employment, is cited as another factor behind inflation.
The outlook for the Fed's Federal Open Market Committee meeting on the 27th and 28th has grown more complicated. According to CME FedWatch, market participants raised the implied probability of a rate increase this month to more than 50% immediately after the CPI release from 22.1% the previous day, before lowering it to 27.1%.
The International Monetary Fund, in its World Economic Outlook report, projected global inflation at 4.7% this year and raised the probability of inflation exceeding 5% next year to 35% from 30% in April. The IMF said core inflation in both the United States and Europe will not fall to 2% until at least the middle of 2028. The fund warned that as fiscal costs rise and electoral pressures mount, central banks could face demands to accommodate more public borrowing or to tolerate inflation above target.
