The U.S. dollar rose against major currencies including the yen and euro as President Donald Trump rekindled trade tensions with new tariffs on Canada and other trading partners. Trump issued a letter late on Thursday that said a 35% tariff rate on all imports from Canada would apply from August 1.

The U.S. dollar has firmed up against its major counterparts, as sentiment toward the greenback improved due to its safe-haven appeal amid the ongoing tariff uncertainties. The U.S. Dollar Index edged up 0.

President Donald Trump says he's prepared to tariff and punish countries that challenge the U.S. dollar as the global reserve currency.
