Year-over-year inflation reached its lowest level in more than three years in July, the latest sign that the worst price spike in four decades is fading and setting up the Federal Reserve for an interest rate cut in September.

Wednesday's report from the Labor Department showed that consumer prices rose just 0.2% from June to July after dropping slightly the previous month for the first time in four years. Measured from a year earlier, prices rose 2.9%, down from 3% in June. It is the mildest year-over-year inflation figure since March 2021.

The government said nearly all the increase last month reflected higher rental prices and housing costs, a trend that, according to real-time data, is easing.

For months, cooling inflation has provided gradual relief to America's consumers, who were stung by the price surges that erupted three years ago, particularly for food, gas, rent and other necessities. Inflation peaked two years ago at 9.1%, the highest level in four decades.

Inflation has taken a central role in the presidential election, with former President Donald Trump blaming the Biden administration's energy policies for the price increases. Vice President Kamala Harris on Saturday said she would soon unveil new proposals to "bring down costs and also strengthen the economy overall."

Biden hailed the "real progress" shown in Wednesday's report, but acknowledged that more needs to be done in order to lower costs for Americans.

"Inflation has fallen below 3% and core inflation has fallen to the lowest level since April 2021," Biden said in a statement. "We have more work to do to lower costs for hardworking Americans, but we are making real progress, with wages rising faster than prices for 17 months in a row."

"Prices are still too high," the president continued. "Large corporations are sitting on record profits and not doing enough to lower prices. That’s why we are taking on Big Pharma to lower prescription drug prices. We’re cutting red tape to build more homes while taking on corporate landlords that unfairly increase rent. And we’re taking on price gouging and junk fees to lower everyday costs from groceries to air travel."

"Congressional Republicans would raise prices for middle class families while cutting taxes for billionaires and big corporations," he concluded. "While they try to take us back, we will fight for the future."

Excluding the volatile food and energy categories, so-called core prices climbed 0.2% from June to July, after a 0.1% increase the previous month. Compared to a year ago, core inflation rose 3.2%, down from 3.3% in June, the lowest since April 2021. Core prices are closely watched by economists because it typically provides a better read of where inflation is headed.

Fed Chair Jerome Powell has said he is seeking additional evidence of slowing inflation before the Fed begins cutting its key interest rate. Economists widely expect the Fed's first rate cut to occur in mid-September.

When the central bank lowers its benchmark rate, over time it tends to reduce the cost of borrowing for consumers and businesses. Mortgage rates have already declined in anticipation of the Fed's first rate reduction.

At a news conference last month, Powell said that cooler inflation data this spring had strengthened the Fed's confidence that price increases are falling back to a 2% annual pace. Another inflation report will be issued next month before the Fed's Sept. 17-18 meeting, with economists expecting that report to also show that price increases remained mostly tame.

Inflation has eased substantially in the past two years as global supply chains have been repaired, a spate of apartment construction in many large cities has cooled rental costs and higher interest rates have slowed auto sales, forcing dealers to offer better deals to potential car buyers.

Consumers, particularly lower-income ones, are also becoming more price-sensitive, forgoing high-priced items or shifting to cheaper alternatives. This has forced many companies to rein in price hikes or even offer lower prices.

Prices are still rising sharply for some services, including auto insurance and health care. Auto insurance costs have shot up as the value of new and used vehicles has soared compared with three years ago. Economists, though, expect those costs to eventually grow more slowly.

As inflation continues to decline, the Fed is paying increasingly close attention to the job market. The central bank's goals, as defined by Congress, are to keep prices stable and support maximum employment.

This month, the government reported that hiring slowed much more than expected in July and that the unemployment rate rose for a fourth straight month, though to a still-low 4.3%. The figures roiled financial markets and led many economists to boost their forecasts for interest rate cuts this year. Most analysts now expect at least three quarter-point rate cuts at the Fed's September, November and December meetings. The Fed's benchmark rate is at a 23-year high of 5.3%.

Still, the rise in the unemployment rate has reflected mainly an influx of job-seekers, especially new immigrants, who haven't immediately found work and so have been classified as unemployed. That is a much more positive reason for a higher unemployment rate than if it came from a jump in layoffs. Measures of job cuts remain low.

On Thursday, the government will release its latest data on retail sales, which are expected to show that consumers increased their spending modestly in July. As long as shoppers are willing to spend, businesses are likely to hold onto their workers and may even add staff.
