President Donald Trump threatened a 35% tariff on some Canadian goods and raised the prospect of increasing levies on most other countries, ramping up his trade rhetoric in comments that weighed on stocks and boosted the US dollar.

President Donald Trump late Thursday threatened a 35% tariff on goods imported from Canada, a dramatic escalation in an on-again, off-again trade war with America’s northern neighbor and one of its most important trading partners.

Something different is happening to the U.S. dollar, which recently completed its worst first half of any calendar year since at least the 1970s: The dollar is strengthening this week, despite President Donald Trump’s ongoing tariff talk.

In a wide-ranging interview with NBC News, Trump talked about tariffs, sending Patriot missiles to NATO for Ukraine and how he'll sell his recently passed "big, beautiful bill."

The twists and turns in U.S. President Donald Trump's tariff policies have not only rattled global financial markets but have also taken investors on a roller-coaster ride. Adding to the uncertainty are tariff-related legal challenges and Trump's assertion that he would hammer out bilateral deals with trade partners.

As the U.S president threatens Canada with blanket 35% tariffs, Paul Donovan, Chief Economist at UBS Global Wealth Management, says the next wave of Trump tariffs may have little or no impact on U.S.

Plus, the Justice Department has subpoenaed 20 doctors and clinics involved in “performing transgender medical procedures on children.”

President Trump said he plans to impose blanket levies of 15% to 20% on most trading partners that haven't yet received suggested tariff rates. That would be higher than the 10% baseline currently in effect.

President Donald Trump’s shock-and-awe tariff campaign is off to a slow start when it comes to reviving American manufacturing jobs.
