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.

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.

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

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.

President Donald Trump has managed to make his erratic trade policies even more baffling to countries desperate to negotiate an escape from his wrath.
