Stock Exchange closes on worst day since 2020 but Trump insists stocks will ‘boom’
The New York stock exchange has closed on its worst day of trading since June 2020 – during the early months of the Covid-19 pandemic.
The main indices saw their worst one-day falls in five years as Donald Trump claimed that “the markets are going to boom” in response to his sweeping tariffs.
The S&P 500 index is down 4.9% at the close, which Reuters flags is the biggest one-day drop since June 2020.
The Dow has also posted its biggest one-day drop since June 2020, down 4%.
Meanwhile, the Nasdaq tumbled 5.9%, its worst single-day performance since March 2020.
The scale of the sell-off, wiping trillions of dollars off the value of US companies, highlights just how alarmed investors are by the tariffs, and the fears they could lead to a recession.
Speaking to reporters earlier on Thursday, Trump denied market turmoil presented a problem. The president said:
I think it’s going very well. It was an operation like when a patient gets operated on and it’s a big thing. I said this would be exactly the way it is … We’ve never seen anything like it. The markets are going to boom. The stock is going to boom. The country is going to boom.

Australia dodged the worst of Donald Trump’s “reciprocal” tariffs yesterday, when the president imposed only the base 10% tariff on the country. But Trump did criticize Australia by name during his speech for not importing more American beef.
Calla Wahlquist in Australia has more on the US-Australia meat trade war:
Australia introduced a ban on US beef imports in 2003, in response to an outbreak of bovine spongiform encephalopathy (BSE) or mad cow disease.
It was technically lifted in 2019, subject to an ongoing biosecurity review that in practice means no imports of fresh beef. The sticking point is the US’s reliance on live cattle imports from Canada and Mexico to bolster its national herd.

The 500 richest people in the world lost a combined $208bn today as stock markets plunged in response to Donald Trump’s sweeping tariff announcement yesterday, Bloomberg reports.
According to the Bloomberg Billionaires Index, which has been active for 13 years, this is the fourth largest one-day drop in billionaires’ wealth.
US billionaires – and Trump allies – like Mark Zuckerberg and Jeff Bezos were the most affected.
In an interview with Newsmax this evening, JD Vance said he thought the stock market response “could be worse” after Donald Trump announced his administration’s “reciprocal” tariffs yesterday.
US stock markets saw their worst day of trading since 2020 today as investors grappled with the implications of Trump’s sweeping tariffs.
“Look, one bad day in the stock market compared to what President Trump said earlier today — and I think he’s right about this — we’re going to have a booming stock market for a long time because we’re reinvesting in the United States of America,” Vance said. “We’re feeling good.”
As Friday morning dawns in Asia, markets are opening lower as investors respond to Donald Trump’s sweeping “reciprocal” tariffs, the highest of which were levied against Asian nations.
Japan’s Nikkei 225 index dropped 2.o7% and South Korea’s Kospi index fell 1.15%.
Meanwhile, in Australia, the S&P/ASX 200 fell 1.06%.
The Health secretary Robert F Kennedy Jr says some personnel let go from and programs shuttered at the Department of Health and Human Services on Tuesday will be reinstated.
He said the cuts were meant to streamline the agency but that “there were a number of instances where studies that should not have been cut were cut, and we’ve reinstated them. Personnel that should not have been cut were cut. We’re reinstating them. And that was always the plan.
“We talked about this from the beginning. We’re going to do 80% cuts, but 20% of those are going to have to be reinstalled because we’ll make mistakes,” he added.
Ted Cruz, the Republican senator from Texas, says he is “not a fan of tariffs” and that he hopes Donald Trump’s are “short-lived”.
Speaking with Fox Business, Cruz said: “I think it is a mistake to assume that we will have high tariffs in perpetuity. I don’t think that would be good economic policy.”
He added that he hoped the president would use the duties as “leverage to lower tariffs across the globe”.
The head of the International Monetary Fund says Donald Trump’s “reciprocal” tariffs “clearly represent a significant risk to the global outlook”.
“It is important to avoid steps that could further harm the world economy,” said IMF managing director Kristalina Georgieva. “We appeal to the United States and its trading partners to work constructively to resolve trade tensions and reduce uncertainty.”
The fund will meet with the World Bank later this month to discuss global economic issues, including the recent US tariffs.

The Trump administration is reportedly now taking aim at Brown University, widening its threats to withhold federal funding for schools deemed to be in conflict with its edicts.
As the fifth university to potentially face a financial hit from the administration, Brown stands to lose $510m over several years, the New York Times reported Thursday, a sizable blow that could seriously impact research.
Brown administrators have not confirmed the news, which was first published by the right-wing website The Daily Caller. But provost Frank Doyle said the university was aware of “troubling rumors emerging about federal action on Brown research grants”, in an email sent to school officials.
From the NYT:
Like many of its Ivy League peers, Brown was the site of clashes over the war in Gaza. But it was also one of a small number of universities that made deals with students to end their protest encampments in the spring, agreements that came under criticism for being too soft on students.
Brown became one of only a handful of universities to agree to a board vote on divesting from Israel. The Brown Corporation, the school’s governing board, ultimately voted against divestment, saying it held no direct investments in companies protesters had named as having ties to Israel.
In recent weeks, as other universities faced backlash over their perceived acquiescence to the Trump Administration, Brown’s leaders spoke out, vowing steadfast commitment to their academic freedoms.
In a letter shared publicly on the university’s site, President Christina H Paxson promised that Brown would not buckle under pressure.
“The nation has witnessed what many in higher education fear may be only the first examples of unprecedented government demands placed on a private university as a condition for restoring federal funding,” she said.
Paxson outlined three core values and the school’s response to protect them: following the law, defending academic freedom and freedom of expression, and a commitment to providing resources to international community members.
“If Brown faced such actions directly impacting our ability to perform essential academic and operational functions,” she said, “we would be compelled to vigorously exercise our legal rights to defend these freedoms, and true to our values, we would do so with integrity and respect.”
19 Democratic AGs sue Trump over elections EO

A coalition of 19 Democratic attorneys general filed a lawsuit against the Trump administration on Thursday, arguing that a recent executive order signed by the president seeking to overhaul the nation’s elections was unconstitutional.
The lawsuit accuses the president of overstepping his authority with last week’s action, which they say amounts to an ”unconstitutional, antidemocratic, and un-American attempt to impose sweeping voting restrictions across the country”.
The lawsuit is the latest challenge to the president’s order, which includes proof-of-citizenship requirements for voter registration and new ballot deadline rules. the order threatens states that don’t comply with federal funding cuts.
It lists President Trump, the attorney general Pam Bondi as defendants. The attorneys general are asking a judge to declare the provisions “unconstitutional and void”.
“My fellow attorneys general and I are taking him to court because this Executive Order is nothing but a blatantly illegal power grab and an attempt to disenfranchise voters, California attorney general Rob Bonta said in a statement. “Neither the Constitution nor Congress authorize the President’s attempted voting restrictions. We will not be bullied by him. We will fight like hell in court to stop him.”
Trump’s elections order also faces legal challenges brought by the Democratic National Committee, the Democratic Governors Association, and Senate and House Democratic leaders, as well as a separate lawsuit filed by two nonprofit organizations, The Campaign Legal Center and the State Democracy Defenders Fund. Both of these lawsuits were filed in the US district court for the District of Columbia.
When Trump signed the order, Will Scharf, the White House staff secretary, called the order “the farthest-reaching executive action taken” in the country’s history.
Despite Trump’s public anti-tax stance, his decision to sharply increase tariffs would amount to the largest tax hike in decades, Reuters reports.
The intel comes from a JP Morgan note, which concluded that the tariffs account for a 22% increase and warns that “sustained restrictive trade policies and reduced immigration flows may impose lasting supply costs that will lower U.S. growth over the long run”.
Trump’s trade policies have spiked risks of a global recession according to the bank, which raised chances to 60% from 40%.
The US stock market closed today on the worst day of trading since 2020, with all three major index funds down as Apple and Nvidia lost a combined $470bn.

While speaking with reporters aboard Air Force One, Trump also mentioned tariffs could give him the power to make a deal with China over TikTok.

He added “we’re very close to a deal with a very good group of people” with “multiple” investors interested in the social media platform.
