Trump, speaking to reporters on Air Force One on his way to the NFL Super Bowl in New Orleans on Sunday, said he would announce the new metals tariffs on Monday.
He also said he would announce reciprocal tariffs on Tuesday or Wednesday, to take effect almost immediately, applying them to all countries and matching the tariff rates levied by each country.
“And very simply, it’s, if they charge us, we charge them,” Trump said of the reciprocal tariff plan.
The largest sources of US steel imports are Canada, Brazil and Mexico, followed by South Korea and Vietnam, according to government and American Iron and Steel Institute data.
Vasu Menon, managing director of investment strategy at OCBC in Singapore said it was unclear whether Trump’s latest announcement was a negotiation strategy.
“After all if implemented it will also hurt the U.S. given its dependence on imported steel and aluminum from Canada and Mexico which are major suppliers of these metals to the US,” Menon said.
“Markets will be on edge and volatile with the escalating trade war and investors need to tread with caution for now and brace for possibly more market turbulence.”
Trump’s comments came as China’s retaliatory tariffs, announced last week, came into effect. The measures target $14bn worth of products with a 15% tariff on coal and LNG, and 10% on crude oil, farm equipment and some vehicles.
