U.S. consumers face an effective U.S. tariff rate of more than 20%, the highest since the early 1900s, the International Chamber of Commerce has estimated following President Donald Trump's import levy announcements this week.

President Donald Trump said in a letter that he will raise taxes on many imported goods from Canada to 35%, deepening a rift between two North American countries that have suffered a debilitating blow to their decades-old alliance.

The letter reiterated Trump’s complaints about dairy quotas, fentanyl and the U.S. trade deficit, which is mostly fueled by American refineries’ thirst for Canadian oil. His social media post caused the Canadian dollar to immediately tumble, indicating the market wasn’t expecting this escalation.

U.S. President Donald Trump said he plans to impose 50% tariffs on all products from Brazil starting August 1, which could have a sharp impact on South America's agricultural powerhouse.

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.

Stocks have hit new highs despite President Trump’s escalating trade war. Some traders may be calling his bluff, but Jamie Dimon of JPMorgan Chase advises caution.
