Trump tariffs wipe out $2 trillion from US stock market

Roughly $2 trillion was erased from the S&P 500 Index on Thursday amid worries that President Donald Trump’s sweeping new round of tariffs could plunge the economy into a recession.

The damage was heaviest in companies whose supply chains are most dependent on overseas manufacturing. Apple Inc., which makes the majority of its US-sold devices in China, fell as much as 9.5 per cent.

Lululemon Athletica Inc. and Nike Inc., among companies with manufacturing ties to Vietnam, were both down more than 12 per cent.

Target Corp. and Dollar Tree Inc., retailers whose stores are filled with products sourced outside of the US, were trading lower by more than 10 per cent.

Few stocks in the US were unscathed with the benchmark index on pace for its biggest decline since 2022. More than 80 per cent of companies in the S&P 500 were trading lower at 10:20 a.m. in New York, with nearly two-thirds of its 500 stocks down at least 2 per cent.

“There’s really not anybody getting spared in absolute terms,” said Garrett Melson, a portfolio strategist at Natixis Investment Managers Solutions. “You’re just wrapped up, today at least, in a broad de-risking, and so it’s kind of just across the board taking chips off the table.”

The breadth and severity of the levies dwarfed those imposed by Trump during his first term, threatening to upend global supply chains, exacerbate an economic slowdown and boost inflation. It also left investors struggling to game out what levies would do to corporate profits.

If Apple, for example, were to absorb the jump in costs as a result of tariffs on China, the iPhone maker’s gross margin could take a hit of as much as 9%, said Citigroup analysts led by Atif Malik.

The plan is equivalent to the largest tax increase since 1968, JPMorgan economist Michael Feroli wrote in a note. It could add as much as 1.5 per cent to prices this year, using the Federal Reserve’s preferred inflation gauge, while weighing on personal incomes and consumer spending.

“This impact alone could take the economy perilously close to slipping into recession,” Feroli wrote. “And this is before accounting for the additional hits to gross exports and to investment spending.” 

US assets quickly emerged as the biggest losers after the announcement. The S&P 500 fell about 4 per cent, and a gauge of the dollar slumped.

The impact elsewhere was muted in comparison: A broad gauge of Asian stocks fell less than 1 per cent and the Stoxx Europe 600 slid 2.6 per cent, while the euro rose about 2.4 per cent against the dollar. 

Semiconductor and industrial companies also took a beating. The Philadelphia Semiconductor Index sank more than 6 per cent, with Micron Technology Inc. down 11% and Broadcom Inc. 7 per cent.

Caterpillar Inc. and Boeing Co., which get a big chunk of sales from China, dropped at least 6 per cent. 

Apple led declines among the "Magnificent Seven" stocks with roughly $275 billion in market value wiped out.

The group, which also includes Tesla, Microsoft, Nvidia, Alphabet, Amazon.com, and Meta Platforms, has been responsible for much of the US stock market’s gains over the last two years.

“We see 5,300 as the near-term target for the S&P 500, but if tariff uncertainty persists or negotiations with trading partners don’t go well, risks of downside through 5,000 become real,” UBS Group AG’s Bhanu Baweja wrote in a note to clients. “The probability of US stocks entering bear market is going higher.”
