President Donald Trump is preparing to announce auto tariffs as soon as Wednesday, according to people familiar with the matter. This move is expected to escalate his ongoing trade disputes with global partners ahead of a broader tariff initiative planned for the following week. The timing of the announcement remains fluid, with sources indicating that it could occur as soon as today or later in the week. The specifics of the tariffs, including their scope, rate, and any potential exemptions, remain unclear. The announcement is anticipated to impact North American automakers, who rely on integrated supply chains across the U.S., Mexico, and Canada. The auto industry has been on alert since Trump hinted at these tariffs earlier in the week. Additionally, the S&P 500 has fallen nearly -1% and the Nasdaq 100 is down -1.7% in response to the news. Trump had previously delayed some auto tariffs on March 6th.
