Wall Street stocks plunged Tuesday on worries about US economic growth and revived doubts about trade wars as the Trump administration sent mixed signals on their detente with China.
A day after global stocks rallied on a weekend US-China announcement suspending new tariffs, international markets mostly pulled back as investor focus shifted to the lack of concrete progress in reaching a long-term agreement to the dispute.
"Can the US and China really resolve their differences in 90 days?" asked Rodrigo Catril, senior strategist at National Australia Bank.
"It seems that more details and signs of progress will be needed if the initial trade truce warm fuzzy feeling is to be sustained."
All three major US indices fell at least three percent, with the broad-based S&P 500 diving 3.2 percent to 2,700.06, leaving it barely positive for the year.
Bourses in London, Paris, Frankfurt and Tokyo also fell.
- A 'Tariff Man' -
Trump, abruptly shifting tone from the weekend emphasis at comity with China, signaled he was more than happy to impose tariffs if a "fair" deal with the Asian giant did not materialize.
"I am a Tariff Man," Trump said on Twitter. "When people or countries come in to raid the great wealth of our Nation, I want them to pay for the privilege of doing so.... We are right now taking in $billions in Tariffs. MAKE AMERICA RICH AGAIN."
In another trade matter, Trump attended a White House meeting with German automakers as the US and European Union work to resolve US complaints about the trade deficit between the two economies.
The US president has for months been threatening tariffs on imported autos, which would primarily hit Germany, but in July pledged not to take any steps against the European Union while efforts to reach a resolution were underway.
- Recession ahead? -
Investors also cited a signal in the US bond market, often seen as an early-warning indicator of a US recession, as a catalyst for one of Wall Street’s worst days of the year.
The difference in yield between the two- and 10-year US Treasury notes has narrowed sharply in recent days, raising concerns about a so-called "inversion" in which interest on short-term bonds overtakes the rate on long-term bonds.
The shift comes amid signs of weakening global growth and mounting expectation of a slowdown in the United States. Most analysts still do not expect a US recession in 2019.
A note from S&P Global Ratings said the US was nearing the "latter" stages of a multi-year growth cycle, predicting that US growth would slow from 2.9 percent in 2018 to 2.3 percent in 2019 and 1.8 percent in 2020.
"If history is a guide, the end to this cycle will likely result from some combination of the bursting of an asset-price bubble, an oil-price spike or a misstep by the Fed (which has been known to tighten monetary policy either too early or too late)," S&P said.
Elsewhere, Britain's Brexit quagmire is coming to a head as lawmakers debate Prime Minister Theresa May's exit deal over the next five days.
In a setback for May, the House of Commons voted 311-293 to force the government to publish the full legal advice it received from the attorney general about the divorce deal May struck with the European Union last month.
A defeat for the prime minister next week in the overall plan could trigger a no-confidence vote leading to early elections, leaving the Brexit process in utter chaos.
