The S&P 500 was 0.3 per cent higher in morning trading after quivering sharply at the start of trading. The index at the centre of many US retirement savings went from a loss of 0.5 per cent to a gain of 1.4 per cent and back down.
The Dow Jones Industrial Average was down 34 points, or 0.1 per cent, as of 10.15am Eastern Time on Wednesday (12.15am Thursday AEST), and the Nasdaq composite was 1.1 per cent higher.
Huge swings have become routine for financial markets worldwide recently, not just day to day but hour to hour, as investors struggle to game out what Trump’s trade war will do to the economy. On Tuesday, the S&P 500 careened between a gain of 4.1 per cent and a loss of 3 per cent for a second straight day of shocking reversals.
Wall Street’s latest moves came after Trump’s latest round of tariffs kicked in after midnight for imports from around the world. That included a 104 per cent tax on things coming from China, and the world’s second-largest economy quickly retaliated by saying it would raise tariffs on US goods to 84 per cent on Thursday.
“If the US insists on further escalating its economic and trade restrictions, China has the firm will and abundant means to take necessary countermeasures and fight to the end” the Ministry of Commerce said.
Such aggressive brinkmanship between the world’s two largest economies is raising fears that tariffs will stick around for a while, which economists and investors expect would create a recession. The European Union on Wednesday also approved tariffs affecting $US23 billion ($38 billion) in US goods in its own retaliatory move.
Some hope still does remain on Wall Street that Trump could lower his tariffs following negotiations with other countries, which is what’s helping to send stock prices upward at times.
“BE COOL!” Trump said on his Truth Social platform shortly after trading began on Wall Street.
“Everything is going to work out well. The USA will be bigger and better than ever before!”
Some of Wednesday’s strongest action was in the US bond market, where Treasury yields rose sharply again. The yield on the 10-year Treasury climbed to 4.37 per cent from 4.26 per cent late Tuesday and from just 4.01 per cent at the end of last week. It approached 4.50 per cent earlier in the morning. That’s a huge move for the bond market and could be an indication of stress.
Analysts say several reasons could be behind the move, including hedge funds and other investors having to sell their Treasury bonds to raise cash in order to make up for sharp losses in the stock market. Investors outside the United States may also be selling their US Treasurys because of the trade war. Both actions would push down prices for Treasurys, which in turn would push up their yields.
Panic on Wall Street as Trump announces new tariffs
Regardless of the reasons behind it, the higher yields on Treasurys add pressure on the stock market and will likely push up rates for mortgages and other loans for US households.
All the uncertainty about tariffs is already making planning more difficult for big US companies.
Delta Air Lines pulled financial forecasts for 2025 Wednesday as the trade war scrambles expectations for business and household spending and depresses bookings across the travel sector.
“With broad economic uncertainty around global trade, growth has largely stalled,” CEO Ed Bastian said in a statement on Wednesday.
“In this slower-growth environment, we are protecting margins and cash flow by focusing on what we can control.”
Walmart, though, said it’s sticking with its forecasts for sales and operating income over the full year.
In stock markets abroad, indexes tumbled across most of Europe and much of Asia.
London’s FTSE 100 dropped 2.2 per cent, Tokyo’s Nikkei 225 sank 3.9 per cent and the CAC 40 fell 2.6 per cent in Paris.
Chinese stocks were an outlier, and indexes rose 0.7 per cent in Hong Kong and 1.3 per cent in Shanghai.
