March consumer inflation expected to be the hottest since 1981

Consumer price inflation in March is expected to have spiked the most since December 1981, driven by higher food costs, rising rents and runaway energy prices.

The consumer price index will be released Tuesday at 8:30 a.m. ET, and economists expect a monthly jump of 1.1% and a year-over-year gain of 8.4%, according to Dow Jones. That compares with February’s increase of 0.8%, or 7.9% year over year, the highest since early 1982.

“It’s going to be ugly,” said Mark Zandi, chief economist at Moody’s Analytics. “It’s a perfect storm — Russian invasion, surging oil prices, China locking down, further disruptions to supply chains, wage growth accelerating, unfilled positions. Just a kind of scrambled mess leading to painfully high inflation. We’re struggling through two massive global supply shocks. It would be hard to imagine we didn’t suffer higher inflation.”

Core inflation, excluding food and energy, is expected to rise a half percent — the same as February — with a year-over-year gain of 6.6%, up from 6.4%, according to Dow Jones.

“The good news is it does look like it will be the peak because of oil prices,” said Diane Swonk, chief economist at Grant Thornton. Oil prices surged shortly after Russia invaded Ukraine in late February, reaching a high for West Texas Intermediate oil futures of $130.50 per barrel in early March. That price has fallen to about $94 per barrel Monday.

Gasoline prices also surged, reaching a national average of $4.33 per gallon of unleaded on March 11, according to AAA. That price Monday was $4.11 per gallon.

“The problem for the Fed is the broadening of inflation from goods into services and also because used car prices might be picking up again,” said Swonk. “The supply chain issues aren’t going away. They’re getting worse.”

Just on base effects, economists say this month or next month could be the peak for inflation. Zandi projects headline CPI will fall to 4.9% by the end of this year.

The Federal Reserve is expected to tighten policy aggressively to rein in the hottest inflation in four decades. Markets expect a half-point hike in May, and economists say a hot inflation report could also bring a half-point hike in June.

“The Fed’s on track. It’s at least a half-percent hike, and the balance sheet reductions starting out,” he said.

The Fed first raised interest rates by a quarter point in March, after cutting the fed funds target rate to zero in early 2020.

Tom Simons, money market economist at Jefferies, expects to see the Fed raise rates by 50 basis points at its May 3 meeting, and he said the CPI should not change that. “If it comes in dramatically higher than expected, which I don’t think it will, it’s going to start talk of a 75-basis-point hike, or an intermeeting hike,” he said. “That’s pretty much nonsense in my opinion.” A basis point equals 0.01%.

Simons said energy prices in CPI are expected to jump 18% in March. “That first half of March was particularly acute post-Russian invasion. Food prices are a similar story but not nearly to the same extent. … Housing again is going to be a pretty significant factor,” he said.

He expects owners’ equivalent rent, or the cost of a home in CPI, to rise about 0.5%, while rents should rise 0.6% month over month. Shelter costs are one area that is expected to keep rising. That would put shelter, which is a third of CPI, up 4.6% year over year.

Swonk said the increases to shelter costs are the highest since early 1990, and they could continue to rise. “I think there’s a risk it comes in on the hot side,” she said.
