The U.S. economy grew at a healthy 3.1% rate in the first three months of this year, but signs are mounting that growth has slowed sharply in the current quarter amid slower global growth and a confidence-shaking trade battle between the United States and China.

The gain in the gross domestic product, the broadest measure of economic health, was unchanged from an estimate made a month ago, the Commerce Department reported Thursday. However, the components of growth shifted slightly with stronger business investment and consumer spending slowing more than previously estimated.

Economists believe growth has slowed sharply in the current April-June quarter to around 2%. They expect similar meager gains for the rest of the year, a forecast that runs counter to the Trump administration’s expectations for strong growth above 3%.

The 3.1% growth in the first quarter marked a rebound from a 2.2% growth rate in the fourth quarter of last year. But it was slower than a sizzling increase of 4.2% in the second quarter and a solid increase of 3.4% in the third quarter last year. For the entire year, GDP grew 3.9%, the best annual gain since 2015.

Last year’s strength was powered by the implementation of a $1.5 trillion tax cut, President Donald Trump’s signature domestic achievement, and billions of dollars in increased government spending on the military and domestic programs Congress approved in early 2018.

However, the impact of the tax cuts and the higher government spending are expected to fade this year, leaving the economy growing very close to the 2.2% average seen over the 10 years of the current expansion, which will become the longest in U.S. history next month.

The Trump administration disputes these forecasts, believing that its economic policies will lift growth to levels of 3% or better over the next six years.

Trump, who is counting on a strong economy as he campaigns for re-election next year, has pushed the Federal Reserve to immediately start cutting interest rates to undo what he sees as the damage from four unnecessary Fed rate hikes last year.

At its meeting last week, the Fed did signal that it was prepared to cut rates if needed to protect the economy from a growing trade dispute between the United States and China.

Trump is scheduled to meet Saturday with Chinese President Xi Jinping at a Group of 20 major nations summit in Japan to see if a way can be found to restart trade negotiations between the world’s two biggest economies.

The trade tensions have increased uncertainty over what higher tariffs on Chinese imports will do to the U.S. economy, resulting in declines in manufacturing activity and a drop in consumer confidence.

Mark Zandi, chief economist at Moody’s Analytics, said if this week’s talks don’t achieve at least a ceasefire in the trade war and Trump carries through with his threats to expand tariffs on $250 billion in Chinese goods to cover virtually all of Chinese imports, that could be enough to trigger a full-blown recession.

“I think we are on the razor’s edge here,” Zandi said. “The real threat now is an expanding trade war which would push growth below potential and result in unemployment starting to rise.”

In the first quarter, consumer spending, which accounts for 70% of economic activity, slowed to a small 0.9% rate of gain, down from a previous estimate of 1.9%. This downward revision was offset by several factors including stronger spending by businesses on investment in such areas as computer software.
