President Donald Trump’s renewed pledges to slap 25% tariffs on imports from Canada and Mexico on Feb. 1 jolted foreign exchange markets late in the New York trading session, sending currencies from both countries plunging against the US dollar.

President Donald Trump says his 25% tariffs on Canada and Mexico are coming on Saturday. Trump also said he'll "probably” decide on Thursday night whether to include oil from those countries as part of his import taxes.

WASHINGTON (Reuters) -U.S. President Donald Trump on Thursday said he would likely decide by the end of the day whether to put a 25% tariff on imports of Mexican and Canadian oil that would take effect on Feb 1. "We may or may not. We're going to make that determination probably tonight," Trump told reporters at the White House.
