A measure of prices that is closely tracked by the Federal Reserve rose 5.8% last year, the sharpest increase since 1982, as brisk consumer spending collided with snarled supply chains to raise the costs of food, furniture, appliances and other goods.

The report Friday from the Commerce Department also said that consumer spending fell 0.6% in December, with purchases of cars, electronics, and clothes declining. Higher prices might have discouraged some shoppers, along with a wave of omicron cases that kept many Americans from traveling, eating out or visiting entertainment venues.

Inflation Hammers Household Budgets

At the same time, incomes rose 0.3% last month, providing fuel for future spending.

Stubbornly high inflation has hammered household budgets, wiped out last year’s healthy wage gains and posed a severe political challenge to President Joe Biden and Democrats in Congress. It also led the Federal Reserve to signal Wednesday that it plans to raise interest rates multiple times this year beginning in March to try to get accelerating prices under control.

With consumer spending likely remaining weak, economists project that growth will slow in the first three months of the year to a 1.5% annual rate or even less. That would be down drastically from a strong 6.9% rate in the final three months of 2021.

In another cautionary sign, a measure of consumer sentiment dropped this month to its lowest level in more than a decade, the University of Michigan reported Friday. Consumers are particularly worried about inflation eroding their incomes.

Still, economists say steady job gains and increased savings should eventually drive more spending later this year, especially if the omicron wave keeps fading.

“You’re going to see the labor market continue to heal, and, the pandemic permitting, the consumer will have enough firepower to grow spending at a reasonable rate as the year goes on,” said Joshua Shapiro, chief U.S. economist at MFR Inc.

Biggest Price Increases Since 1983

Most analysts still expect inflation to decelerate this year, though it will likely remain high as rents and wages increase.

Excluding the volatile food and energy categories, so-called core prices rose 4.9% last year, the biggest increase since 1983. That was up from a 4.7% year-over-year rise in core prices in November.

From November to December, prices rose 0.4%, down from a 0.6% increase from October to November. Core prices rose 0.5% for a second straight month.

The economy is expanding at its fastest pace in decades, and job creation reached a five-decade high last year. But the rebound occurred so quickly after the pandemic shutdowns that it left many companies flat-footed, with fewer workers and supplies than they needed. Spending on autos, electronics and other goods jumped 12% in 2021, the government reported Wednesday, the biggest increase since 1946.

Besides raising interest rates, Chair Jerome Powell said Wednesday that the Fed will move to shrink its huge $8.9 trillion of bond holdings this year, another step that will likely tighten credit, slow spending and potentially weaken the economy.

Speaking at a news conference, Powell acknowledged that inflation has gotten “slightly worse” in the past month. He cautioned that higher prices “have now spread to a broader range of goods and services,” after initially affecting sectors of the economy, like factory-made products for homes, that were most disrupted by the pandemic.

Possible ‘Wage-Price Spiral’

Powell also said the Fed is increasingly focused on the question of whether rising wages are acting as a primary driver of inflation, by forcing companies to charge more to cover their higher labor costs. Such a “wage-price spiral,” which the United States hasn’t experienced since the 1970s, can make inflation difficult to cool.

A separate report Friday provided some signs of cooling on that front. The Labor Department said that workers’ salaries and benefits jumped 4% last year. That was the biggest rise in two decades. But over the past three months, the increase slowed from 1.3% to 1% and dropped even more for a category that includes restaurant and hotel workers.

Powell has said that a sharp rise in pay and benefits, reported in November, was a key reason why the Fed began shifting its policy toward higher interest rates. While rising wages are good for employees, they can also elevate inflation if they aren’t offset by efficiency gains.

The inflation figure that the government reported Friday is its personal consumption expenditures index. Though the consumer price index is a better-known barometer, the Fed tends to track the PCE in setting its interest rate policies. The PCE index tracks actual purchases consumers make each month, while the CPI follows a fixed market basket of goods.

Earlier this month, the government said the CPI jumped 7% last year, also the fastest pace in nearly four decades.

McDonald’s Prices up 6%

On Thursday, McDonald’s said that while sales last year grew at a healthy pace, higher costs for food and paper products and the need to raise pay to attract and keep workers eroded profits even after it had raised prices 6% last year.

Likewise, Procter & Gamble said last week that it plans to raise prices for detergents like Tide, Gain, and Downy and for personal care products. The company anticipates price increases for chemicals and other commodities this year.

Higher prices may be weighing on some Americans’ willingness to spend. Still, last month’s drop in consumer spending is likely to be temporary. Americans are already showing signs of heading back out to restaurants and movie theaters as the huge jump in omicron infections has started to decline.

JPMorgan Chase says spending on its credit cards for hotels, travel, and entertainment venues has rebounded this month, after falling in December. Spending has risen more in states where COVID-19 cases have come down the most.
