Prices were 8.5% higher in March than a year earlier.

Some shortages of goods have abated in recent months as companies have built up extra inventories in storerooms and warehouses. But the disruptions that have plagued supply chains, adding to price pressures around the world, continue to show signs of worsening, suggesting that American consumers may see more shortages of products like electronics — and potentially further price increases — in the months to come.

In particular, sweeping lockdowns in China to try to stamp out the Omicron variant of the coronavirus have been posing new risks to America’s supply of manufacturing components and finished goods. Although China has tried to keep its ports functioning through the pandemic, restrictions on truck drivers have stemmed the flow of electronics, car parts and other goods out of the country.

Ariane Curtis, global economist at Capital Economics, said in a note last week that, in developed markets, “renewed shortages — particularly of electrical goods — and higher shipping costs could keep goods inflation higher for longer than we currently expect.”

The company had forecast inflation in advanced economies to moderate during the year, but the war in Ukraine has taken a toll on European supply chains, while lockdowns in China risk further product shortages in the United States, she said.

Freight rates have dipped slightly in recent weeks, but they remain far higher than they were before the pandemic. The price to ship a 40-foot container from China to the West Coast of the United States was $15,817 as of Friday, up from $5,893 one year ago and from $1,584 at the same time in 2019, according to data from Freightos, a freight-tracking firm.

Omair Sharif, the president of the research firm Inflation Insights, said it was impossible to accurately forecast how long Chinese lockdowns might continue to disrupt global supply chains and therefore what their inflationary impact would be. But companies have recently made progress building up inventories that were badly stretched earlier in the pandemic, he said, and those excess goods will help cushion the inflationary impact.

Consumers also appear to be cutting back their spending on goods, probably to offset higher food and gasoline prices, Mr. Sharif said.

“People are pulling back because of inflation and high prices elsewhere, so stuff is starting to pile up a bit at the warehouses,” he said. “With inventories we are definitely in a better position to handle a slowdown without a big knock-on effect on inflation.”

Phil Levy, the chief economist at Flexport, a logistics company, said there was “tremendous concern within the logistics industry that companies have overdone it on orders, are accumulating excess inventories” and will pull back.

But the forecast for inflation is complex, he said, since international shipping lanes simultaneously remain congested and the Chinese lockdowns appear likely to cause further interruptions in the flow of goods. And much of what happens with inflation this year will depend on trends in consumer demand.

“The crystal ball is unusually murky right now,” Mr. Levy said.
