Today marks the implementation of broad 25% tariffs on all imports from Mexico and Canada, as confirmed by President Donald Trump in recent comments. This decision follows a month-long delay intended to facilitate negotiations between the United States, Mexico, and Canada aimed at addressing issues related to drug trafficking and migration at the U.S. border.

The announcement of the tariffs has led to significant volatility in the financial markets. In response to the news, all three major U.S. stock indexes experienced declines. The S&P 500 dropped by 1.8%, marking its largest loss since December, while the Dow Jones Industrial Average fell by 1.5%. The Nasdaq Composite led the decline with a significant decrease of 2.6%, driven in large part by Nvidia’s nearly 9% drop. As a further indication of market instability, the Canadian dollar and Mexican peso both slipped to their lowest levels in a month.

In anticipation of the tightening of trade relations, Mexico has already taken proactive measures, deploying 10,000 National Guard troops to reinforce its northern border. This mobilization is part of a broader strategy to combat drug trafficking and unauthorized migration. Meanwhile, Canada has appointed a fentanyl czar to address the issue of fentanyl smuggling, despite the fact that less than 1% of fentanyl entering the U.S. originates from Canada.
