Two days after President Donald Trump announced his expansive global tariffs, the United States confronted wide-ranging and painful blowback, as China retaliated against U.S. goods and markets plummeted again on worries of a persistent, damaging trade war.

No portion of the global economy appeared unscathed as the world braced for Trump to begin imposing his nearly across-the-board taxes on imports Saturday, marking the first salvo in a potentially costly trade conflict that the president has vigorously defended.

China, which Trump has already hit with 20% tariffs, announced plans to retaliate. Beijing promised to impose a 34% tariff on U.S. goods next week, including on agricultural products. China calibrated its tariffs to match Trump’s decision to add a 34% tax to Chinese imports.

The tit-for-tat delivered a huge blow to financial markets, as Wall Street reckoned with the rising odds of an escalating global trade standoff. By the closing bell, the S&P 500 had fallen by almost 6%, pulling it closer to a bear market, a widely used Wall Street term for a decline of at least 20% from its peak. The tech-heavy Nasdaq fell 5.8%, pushing it into bear market territory.

As China took aim at the United States, Ngozi Okonjo-Iweala, the director general of the World Trade Organization, warned Friday against a “cycle of retaliatory measures that lead to further declines in trade.” In the United States, Jerome Powell, the chair of the Federal Reserve, struck his own downbeat note over the unpredictable trajectory of the economy.

“While uncertainty remains elevated, it is now becoming clear that the tariff increases will be significantly larger than expected,” Powell said. “The same is likely to be true of the economic effects, which will include higher inflation and slower growth.”

Trump stands by plan

But Trump responded to the day of chaos by striking a defiant tone. Having decamped from Washington to Mar-a-Lago, his home in Florida, he declared on Truth Social: “MY POLICIES WILL NEVER CHANGE.”

Instead, the president insisted his strategy was “ALREADY WORKING,” he said in another post, as he held up a newly released and better-than-expected jobs report, which reflected U.S. hiring increased in the month before the announcement of his tariffs.At one point, the president even circulated another user’s video that argued “Trump is purposely CRASHING the market,” in a bid to force the Fed to lower interest rates. He later called on Powell to do just that, demanding the independent chair of the central bank “STOP PLAYING POLITICS.”

And Trump eventually turned his attention to China, attacking the country for having “PLAYED IT WRONG” by retaliating against the United States. The president and his aides previously have signaled they could ratchet up their tariff rates if other nations look to exact retribution on U.S. goods.

The global scramble in many ways underscored the weight of Trump’s tariffs and the significance of his grand aspirations to recalibrate the global trading system. The White House sees these levies as critical toward resetting U.S. trade relationships, which the president contends are unfair, while boosting U.S. manufacturing and raising new revenue.

Economists pessimistic

But the tariffs, which are taxes on imports, threaten to fall hard on businesses that could face new costs to produce their goods. That, in turn, could hammer consumers, who are likely to shoulder the burden of any price increases. Economists widely believe the result could be a rising rate of inflation, and a slowdown in consumer spending and business investment, which together crimp U.S. growth and push the economy into a recession.

“Markets are expressing a vote of no confidence in the new tariff regime,” said Joe Brusuelas, principal and chief economist at the consulting firm RSM. He added that Trump’s commentary Friday only “adds to the consternation and concern that there’s no strategic road map.”

But Trump and his top aides have swatted away those dour projections in recent days. Fanning cable news, they have dismissed the ebb and flow of the markets and acknowledged the possibility that tariffs could create short-term economic pain, which the president has likened to a “sick” patient receiving a painful yet necessary medical operation.

The administration and its conservative allies have also labored to deflect criticism from economists, repeatedly portraying them as naysayers who had wrongly judged the president’s agenda in the past.

“I think it’s very clear the rhetoric of the economic community, in particular, is almost entirely ideological and out of proportion to the actual sort of risk-reward calculation,” Oren Cass, chief economist at American Compass, a conservative economic think tank, said Friday.

Global leaders, U.S. politicians and others rejected that view, saying that Trump’s approach threatened to weaken the global economy and send prices soaring just as much of the world was finally returning to a sense of balance after two years of rapid inflation.

Okonjo-Iweala, director general of the WTO, warned in a statement Friday that Trump’s policies “could lead to an overall contraction of around 1% in global merchandise trade volumes this year, representing a downward revision of nearly four percentage points from previous projections.”
