Inflation hits another 40-year high. What does that mean for shoppers and the next Fed rate hike?

Inflation jumped again in June on a persistent climb in gas, food and rent costs, notching another 40-year high and likely solidifying the Federal Reserve’s plans for another big rate hike this month.

Prices increased 9.1% from a year earlier, up from an annual rate of 8.6% the prior month and the largest gain since November 1981, the Labor Department's Consumer Price Index showed Wednesday. Economists surveyed by Bloomberg had estimated inflation would rise to 8.8%.

On a monthly basis, consumer prices increased 1.3%, the largest such leap since 2005, compared with a 1% rise in May.

"Ouch," Ian Shepherdson, chief economist of Pantheon Macroeconomics, wrote in a research note of the latest surge in prices. "But this will be the last big increase."

Amid signs that inflation is poised to gradually ease, he, along with other economists, noted June likely marked its peak, though a similar pronouncement in the spring proved premature.

Stock market reaction

The report bolsters the Federal Reserve's plans in two weeks to raise its key interest rate by a hefty three-quarters of a percentage point for a second straight month as part of an aggressive campaign to curtail inflation.

The inflation figure and likelihood of a substantial rate hike disappointed already dour investors. Stocks ended the day lower, with the broad S&P 500 stock index down around 17 points, or 0.50%, while the Dow Jones Industrial Average fell more than 200 points, or 0.70%.

What is causing inflation?

June’s surge again was led by gasoline prices, which increased 11.2% from the prior month and 59.9% annually. The good news is unleaded regular averaged $4.65 Tuesday, down from $5 a month ago.

Grocery prices rose by 1% from May and 12.2% over the past 12 months. Both gas and food costs have been elevated largely because Russia’s war in Ukraine has disrupted global supplies of oil, wheat, corn and other commodities.

In June, cereal prices rose 2.5% from the prior month and 14.2% from a year ago. Bread was up 1.6% monthly and 10.8% annually. Chicken costs increased by 1.5% from May and 17.3% yearly.

There were some encouraging signs. Bacon prices fell 1.9%, its second straight large monthly decline. And beef and veal prices decreased by 2.3%.

Will food prices go down?

Commodity prices have tumbled recently amid recession fears and ebbing consumer demand. That already has pushed down gas prices and set the stage for more moderate food price increases within months, says Wells Fargo economist Sam Bullard.
