But key drivers — consumers and businesses — continue to spend.

The nation’s economy slowed sharply last quarter to a 1.6% annual pace in the face of high interest rates, but consumers — the main driver of economic growth — kept spending at a solid pace.

Thursday’s report from the Commerce Department said the gross domestic product — the economy’s total output of goods and services — decelerated in the January-March quarter from its brisk 3.4% growth rate in the final three months of 2023.

A surge in imports, which are subtracted from GDP, reduced first-quarter growth by nearly 1 percentage point. Growth was also held back by businesses reducing their inventories. Both those categories tend to fluctuate sharply from quarter to quarter.

By contrast, the core components of the economy still appear sturdy. Along with households, businesses helped drive the economy last quarter with a strong pace of investment.

The import and inventory numbers can be volatile, so “there is still a lot of positive underlying momentum,’’ said Paul Ashworth, chief North America economist at Capital Economics.

The economy, though, is still creating price pressures, a continuing source of concern for the Federal Reserve. A measure of inflation in Friday’s report accelerated to a 3.4% annual rate from January through March, up from 1.8% in the last three months of 2023 and the biggest increase in a year. Excluding volatile food and energy prices, so-called core inflation rose at a 3.7% rate, up from 2% in fourth-quarter 2023.

From January through March, consumer spending rose at a 2.5% annual rate, a solid pace though down from a rate of more than 3% in each of the previous two quarters. Americans’ spending on services — everything from movie tickets and restaurant meals to airline fares and doctors’ visits — rose 4%, the fastest such pace since mid-2021.

But they cut back spending on goods such as appliances and furniture. Spending on that category fell 0.1%, the first such drop since the summer of 2022.

The economy’s gradual slowdown reflects, in large part, the much higher borrowing rates for home and auto loans, credit cards and many business loans that have resulted from the 11 interest rate hikes the Fed imposed in its drive to tame inflation.

Even so, the United States has continued to outpace the rest of the world’s advanced economies. The International Monetary Fund has projected that the world’s largest economy will grow 2.7% for all of 2024, up from 2.5% last year and more than double the growth the IMF expects this year for Germany, France, Italy, Japan, the United Kingdom and Canada.
