Stocks fell sharply on Tuesday after a top U.S. trade official indicated that higher tariffs on Chinese goods are coming later this week, disappointing traders who hoped President Donald Trump's weekend tweet threat was just a negotiation tactic.
The Dow Jones Industrial Average fell 473.39 points, or 1.79%, to 25,965.09 after plunging as much as 648.77 points at its low of the day, while the dropped 1.65% to 2,884.05. It was the Dow's biggest drop since January 3. The Nasdaq Composite dropped 1.96% to 7,963.76. All 30 of Dow components fell and all 11 S&P sectors traded lower in the broad sell-off.
Shares of trade bellwethers Caterpillar and Boeing fell 2.26% and 3.87%, respectively. Boeing also broke below its 200-day moving average for the first time since January. Chipmakers, especially vulnerable if China retaliates, led the tech sector lower as Nvidia dropped 3.75%. Apple also fell 2.7%.
U.S. Trade Representative Robert Lighthizer told reporters that the U.S. will increase levies on Chinese imports on Friday.
Lighthizer's comments "further increased the likelihood of a tariff step up," Keith Parker, a strategist at UBS, said in a note. A full-blown trade war would shave off 45 basis points from global economic growth, while China's GDP would take a hit of between 1.2% and 1.5%.
"We still see a trade war as low probability given the next tranche of tariffs would hit US consumer goods, but nevertheless it would have a big negative impact," he said.
Lighthizer made his remarks after President Donald Trump tweeted he would raise current tariffs 10% on $200 billion of Chinese goods to 25% on Friday. He also threatened to impose an extra 25% levy on another $325 billion of Chinese goods "shortly."
Trump's tweets initially sent the market reeling on Monday. The Dow fell as much as 471 points while the Nasdaq dropped 2% at one point. However, equities rebounded to close well off their lows on news that a Chinese delegation would come to Washington for talks and as traders bet that Trump's tweet was just bluffing.
But Lighthizer's comments dashed those hopes. The selling on Tuesday accelerated after the Dow broke through Monday's lows.
The Cboe Volatility Index, a measure of the 30-day implied volatility of the S&P 500 known as the "VIX" or the "fear gauge," hit a fresh high of 21.09 on Tuesday, its highest level since January 22.
"I think this is a big masquerade by the administration. I think they're preparing the market for the worst-case scenario but a trade deal is probably going to happen," said Peter Cardillo, chief market economist at Spartan Capital Securities. "I still think we'll get some sort of positive announcement on Friday."
Chinese Vice Premier Liu He is expected to join a delegation in the United States this week. However, he will only attend the negotiations on Thursday and Friday. He was originally scheduled to attend negotiations Wednesday through Saturday.
"The Trump administration seems to have concluded that it is time to get it done. In other words, it's either deal or no deal," said Ed Yardeni, president and chief investment strategist at Yardeni Research, in a note. But "I expect that the US and China will settle their differences on trade issues sooner rather than later."
"Both the premier of China and the president of the United States want to come across that they prevailed and didn't give in," he said.
In recent months, both China and the U.S. have indicated that trade talks were heading toward a resolution that would end the ongoing trade war between the world's largest economies. Treasury Secretary Steven Mnuchin told The New York Times last month that negotiations were in the "final laps."
The positive news helped push the S&P 500 and Nasdaq to record highs this year. The indexes are up still up 15% and 20%, respectively. The Dow, meanwhile, is up 11%.
"The market was just very complacent thinking a deal would happen," said Sandy Villere, portfolio manager at Villere & Co. "If they look forward, I think investors will see more volatility and lower overall returns with low interest rates."
Villere sees the higher volatility as a buying opportunity, "but we've got to get through this trade war."
