Financial markets, which have shown increasing insensitivity to tariff threats from the US, will face a test at the Monday open after President Donald Trump declared a 30% rate for the European Union and Mexico effective Aug.

America’s biggest trading partners have tried tactics ranging from appeasement to retaliation to avoid higher tariffs. All find themselves faced with similar threats from Washington.

President Donald Trump posted letters to the leaders of Mexico and the European Union, saying they had not done enough to head off the new tariffs.

President Donald Trump has posted two new letters on his social media platform announcing tariffs on the European Union and Mexico.

Businesses typically pass tariff costs onto consumers through higher prices. Sometimes, that process is less subtle.

Trump and his aides have repeatedly shifted their stance on tariffs since the president’s “Liberation Day” announcement.

The pause on the biggest of Trump's tariffs won't end this week, but the president continues to pledge steep new duties against major countries.
