Here's the inflation breakdown for March 2024 — in one chart

Inflation jumped in March as prices for consumer staples such as gasoline edged higher and those for housing remained stubbornly high, suggesting inflation may be a bit stickier than it seemed just a few months ago, economists said. The consumer price index, a key inflation gauge, rose 3.5% in March from a year ago, the U.S. Labor Department reported Wednesday. That's up from 3.2% in February. CPI measures how fast prices are changing across the U.S. economy. It measures everything from fruits and vegetables to haircuts, concert tickets and household appliances.

The March inflation reading is down significantly from its 9.1% pandemic-era peak in 2022, which was the highest level since 1981. However, it remains above policymakers' long-term target, around 2%. Progress in the inflation fight has somewhat flatlined in recent months. "The disinflation has stalled out," said Mark Zandi, chief economist at Moody's Analytics. "The big rock in the way here is the cost of shelter," Zandi said. While housing costs have moderated, they account for the largest share of the CPI inflation index and "are still growing strongly," he said.

Despite progress having stalled, broader evidence doesn't suggest a renewed surge in inflation — though it may take longer than expected to bring the rate back to target, economists said. In fact, underlying inflation after stripping out shelter costs is already back to target, Zandi said. "I still hold to the view that inflation is moderating," Zandi said. "It's just taking frustratingly long to get there."

Household paychecks can buy more stuff, though

Higher oil and gas prices take a toll

Gasoline prices increased 1.7% from February to March, the Bureau of Labor Statistics said. This figure is adjusted to account for seasonal buying patterns. Average U.S. pump prices were $3.52 a gallon on April 1, up from $3.35 on March 4, according to weekly data published by the Energy Information Administration.

The increase is largely attributable to higher oil prices. They've firmed amid a generally positive outlook for the global economy, meaning greater global oil demand, and controlled output among major oil-producing nations, meaning there hasn't been a glut of oil, economists said. Tensions in the Middle East may also be playing a role, Hamrick said.

Higher gas prices may filter through to higher prices elsewhere, since they factor into transportation and distribution costs for goods and even services such as food delivery, he said. Higher energy prices are what worries Zandi most relative to inflation readings. It's likely the upward trend will continue in coming months, and the dynamic negatively impacts consumer buying power and sentiment, he said. "Nothing does more damage to the economy more quickly than rising oil and gasoline prices," he said.

Other 'notable' areas of inflation

The BLS said that motor vehicle insurance, medical care, recreation and personal care, in addition to shelter, were "notable" contributors to "core" inflation, a reading that strips out volatile energy and food prices. Shelter, motor vehicle insurance, medical care, apparel and personal care were notable contributors to monthly inflation from February to March, the agency said.

The overall monthly CPI reading, 0.4%, was much higher than the roughly 0.2% that would be expected on a consistent basis to bring inflation back to normal, economists said. "There is no improvement here; we're moving in the wrong direction," Hamrick said. "The usual trouble spots persist," said Hamrick, who additionally called out costs for electricity and car maintenance and repairs.

Prices have fallen in some categories

Meanwhile, some consumer categories have seen improvement. Prices fell for used cars and trucks, new vehicles and airline tickets between February and March, for example. They're also down over the past year, by 2.2%, 0.1% and 7.1%, respectively, according to CPI data. Lower prices for new and used cars should lead auto insurance and repair costs to fall as well, economists said.

Grocery prices are another bright spot, they said. While some categories, such as eggs and pork chops, have seen recent upward movement, the overall "food at home" index stood at 0% on a monthly basis in both February and March. "Food prices have come to a standstill," Zandi said. "For most Americans, the thing that bothers them the most about inflation is high food prices."

Supply-and-demand dynamics

At a high level, supply-and-demand imbalances are what trigger out-of-whack inflation. For example, the Covid-19 pandemic disrupted supply chains for goods. Americans' buying patterns also simultaneously shifted away from services — such as entertainment and travel — toward physical goods since they stayed at home more, driving up demand and fueling decades-high goods inflation. Additionally, supply-and-demand dynamics in the labor market pushed wage growth to the highest level in decades, putting upward pressure on prices for services, which are more wage-sensitive. Now that supply-chain issues are "pretty close to fixed," there's "little scope" for goods to contribute to disinflation moving forward, said Sarah House, senior economist at Wells Fargo Economics.
