WASHINGTON, United States — US retail sales unexpectedly fell in February, the latest sign economic growth has shifted into low gear as stimulus from $1.5 trillion in tax cuts and increased government spending fades.

The weak report from the Commerce Department on Monday joined a raft of other soft data, including housing starts and manufacturing production that have left economists anticipating a sharp slowdown in growth in the first quarter.

The loss of economic momentum also reflects higher interest rates, slowing global growth, Washington's trade war with China and uncertainty over Britain's departure from the European Union. These factors contributed to the Federal Reserve's decision last month to abruptly end its three-year campaign to tighten monetary policy.

The US central bank abandoned projections for any interest rate hikes this year after increasing borrowing costs four times in 2018.

Retail sales dropped 0.2 percent as households cut back on purchases of furniture, clothing, food and electronics and appliances, as well as building materials and gardening equipment. Data for January was revised higher to show retail sales increasing 0.7 percent instead of gaining 0.2 percent as previously reported.

Economists polled by Reuters had forecast retail sales rising 0.3 percent in February. Retail sales in February advanced 2.2 percent from a year ago.

The surprise drop in sales in February could partly reflect delays in processing tax refunds in the middle of the month. Tax refunds have also been smaller on average compared to prior years following the revamping of the tax code in January 2018. Cold and wet weather could also have hurt sales.

The February retail sales report was delayed by a 35-day partial shutdown of the federal government that ended on January 25. March's retail sales report, which was scheduled for publication on April 16, will be released on April 18.

The dollar slipped against a basket of currencies after the report. US Treasury prices pared losses.

Excluding automobiles, gasoline, building materials and food services, retail sales fell 0.2 percent in February after an upwardly revised 1.7 percent surge in January. These so-called core retail sales correspond most closely with the consumer spending component of gross domestic product.

They were previously reported to have rebounded 1.1 percent in January. Consumer spending accounts for more than two-thirds of economic activity. The sharp upward revision to core retail sales in January was insufficient to reverse December's more than 2.0 percent plunge, leaving expectations for tepid GDP growth in the first quarter intact.

Growth estimates for the January-March quarter are as low as a 0.8 percent annualised rate. The economy grew at a 2.2 percent rate in the fourth quarter after expanding at a 3.4 percent clip in the July to September period.

In February, sales at building materials and garden equipment and supplies dealers tumbled 4.4 percent, the biggest drop since April 2012. Receipts at clothing stores fell 0.4 percent and those at furniture outlets dropped 0.5 percent.

Sales at food and beverage stores declined 1.2 percent, the biggest drop since February 2009. Receipts at electronics and appliances stores fell 1.3 percent, the largest decline since May 2017.

But consumers bought more motor vehicles, with sales at auto dealerships rebounding 0.7 percent after declining 1.9 percent in January. Households also spent more at service stations, likely reflecting higher gasoline prices.

Online and mail-order retail sales rose 0.9 percent. Sales at restaurants and bars edged up 0.1 percent and spending at hobby, musical instrument and book stores increased 0.5 percent.
