The US inflation rate was higher than forecast in August, keeping up pressure on the Federal Reserve for a large interest rate rise this month.
The consumer price index increased 0.1 per cent for the month, above economists’ expectations for a 0.1 per cent drop, as a fall in energy costs failed to fully offset increases in services and other spending categories
The figures, published by the Bureau of Labor Statistics, also contrasted with July, when prices did not rise on the previous month.
On an annual basis, headline inflation is running at 8.3 per cent, down from 8.5 per cent in July, but still near a four-decade high. Economists expected a reading of 8.1 per cent.
Financial markets reversed course following the hotter-than-expected inflation figures. Futures for the S&P 500 indicated Wall Street’s benchmark stock index would open 2.4 per cent lower on Tuesday morning, having been up 0.7 per cent before the data were released.
In government debt markets, the yield on the 2-year US Treasury, which is more sensitive to changes in interest rate expectations, surged to be up 0.13 percentage points at 3.70 per cent, having traded at 3.52 per cent beforehand.
“We don’t really see anything in here that would make the Fed want to opt for a slower pace of rate hikes this month,” said Brian Coulton, chief economist at Fitch Ratings.
The surprising jump came despite petrol prices having tumbled in recent months. Earlier this summer, they topped a record $5 a gallon earlier in the summer following a jump in oil prices after Russia’s full-scale invasion of Ukraine. The current national average is $3.70, according to the American Automobile Association.
However, once prices for energy and food are stripped out, core CPI rose further. Between July and August, it increased 0.6 per cent, translating to an annual increase of 6.3 per cent. That is up from the 5.9 per cent recorded during the previous period.
The latest CPI report is the last big data release before the US central bank’s next policy meeting, at which officials are expected to implement a third consecutive 0.75 percentage point rate rise.
That will lift the federal funds rate to a new target range of 3 per cent to 3.25 per cent. By the end of the year, futures markets suggest the benchmark policy rate will settle between 3.75 per cent and 4 per cent.
Petrol prices dropped 10.6 per cent in August, leading to a 5 per cent decline in the overall energy prices. Prices for airlines tickets fell 4.6 per cent, after tumbling 7.8 per cent in July, while prices for used cars also dropped.
A 0.7 per cent jump in shelter-related costs counteracted those declines, however. Year-over-year, they are up 6.2 per cent. Food prices increased 0.8 per cent, following July’s 1.1 per cent jump, translating to an 11.4 per cent annual rise.
Owing to higher prices across the transportation services sector as well as those for medical care, services inflation ex-energy rose 0.6 per cent, or 6.1 per cent higher from the same time last year.
In recent weeks, Fed policymakers have reaffirmed their commitment to bringing inflation under control, emphasising the risks associated with allowing price pressures to persist.
Failing to bring down inflation, and allowing expectations of future price increases to spiral, was likely to mean more economic pain later on, chair Jay Powell and vice-chair Lael Brainard warned last week.
As petrol prices have fallen, so too have expectations about future inflation. Data released by the New York branch of the Fed on Monday showed that households now expect inflation to settle at 5.7 per cent in a year’s time, down from 6.2 per cent.
Policymakers worry this downward trend will not be sustained, however, especially if energy prices jump later this year. Treasury secretary Janet Yellen warned of that possibility over the weekend, citing concerns about a widespread shortage across Europe as the bloc stops buying oil from Russia.
Christopher Waller, a governor who sits on the Federal Open Market Committee, said on Friday that he supported “another significant increase” to the benchmark policy rate at the September gathering. He noted that the US economy’s resilience and the strength of the labour market gave the Fed “the flexibility to be aggressive” in its fight against inflation.
US president Joe Biden is expected to host an event at the White House on Tuesday afternoon to celebrate passage of the Inflation Reduction Act — a package of measures approved by Congress in August that includes incentives for clean energy and some higher taxes on the wealthy and large companies. While economists do not believe the legislation will have an immediate effect on inflation, it could ease price pressures over the longer term.
High inflation has dogged the economic recovery for months, handing Republicans an advantage heading into midterm elections in November.
