US economic growth accelerated in the first quarter, but the burst in growth was driven by a smaller trade deficit and the largest accumulation of unsold merchandise since 2015, temporary factors that are likely to reverse in the coming quarters.
Gross domestic product increased at a 3.2 percent annualized rate in the first quarter, the Commerce Department said in its advance GDP report released on Friday. Growth was also boosted by an increase in government investment.
But consumer and business spending slowed sharply, and investment in homebuilding contracted for a fifth straight quarter, giving the report a weak tone.
While the report suggested there is no recession on the horizon, its details painted a picture of an economy that is slowing as the stimulus from the White House's $1.5 trillion tax cut package fades and the effects of past interest rate increases by the Federal Reserve linger.
Fears of a recession were stoked by a brief inversion of the US Treasury yield curve last month.
"The gain in first-quarter GDP would seem to make a mockery of claims that the US economy is slowing as the fiscal stimulus fades," said Paul Ashworth, chief US economist at Capital Economics in Toronto. "Looking beyond the headline number, however, there are plenty of causes for concern."
The economy grew at a 2.2 percent pace in the October-December period. Economists polled by Reuters had forecast GDP increasing at a 2.0 percent rate in the first three months of the year. Growth has stepped down from a peak 4.2 percent pace in the second quarter of 2018. The economy will mark 10 years of expansion in July, the longest on record.
Fed officials are likely to shrug off the surge in growth last quarter and focus on a measure of domestic demand that increased at only a 1.3 percent rate, the slowest since the second quarter of 2013. It increased at a 2.6 percent pace in the October-December quarter.
The Fed recently suspended its three-year monetary policy tightening campaign, dropping forecasts for any rate hikes this year. The US central bank increased borrowing costs four times in 2018.
US Treasury yields jumped after the release of the data before retracing and the US dollar rose against a basket of currencies before reversing course. US stock index futures were trading mixed.
Exports surged and imports declined in the first quarter, leading to a small deficit that added 1.03 percentage points to GDP after being neutral in the fourth quarter. Trade tensions between the United States and China have caused wild swings in the trade deficit, with exporters and importers trying to stay ahead of the tariff fight between the two economic giants.
The standoff has also had an impact on inventories, which increased at a $128.4 billion rate in the first quarter, the strongest pace since the second quarter of 2015. Inventories increased at a $96.8 billion pace in the October-December quarter. Part of the inventory build was because of weak demand, especially in the automotive sector, which is expected to weigh on future production at factories.
Inventories contributed 0.65 percentage point to first-quarter GDP after adding one-tenth of a percentage point in the October-December period.
Growth in consumer spending, which accounts for more than two-thirds of US economic activity, slowed to a 1.2 percent rate from the fourth quarter's 2.5 percent rate. The moderation in spending reflected a decline in motor vehicle purchases and other goods, likely related to a 35-day shutdown of the federal government. There was also a slowdown in spending on services.
The government said while it could not quantify the full effects of the shutdown, it estimated that reductions in labour services supplied by federal workers and intermediate purchases of goods and services by non defense agencies had subtracted three-tenths of a percentage point from GDP last quarter.
Business spending on equipment braked sharply, rising at only at a 0.2 percent rate, the slowest since the third quarter of 2016. Spending was held down by weak outlays on agricultural machinery and office furniture. Investment in structures contracted for a third straight quarter.
Residential construction fell at a 2.8 percent rate, marking the fifth straight quarterly decline. Government investment rebounded at a 2.4 percent rate, driven by spending at state and local governments.
