Auto parts and vehicles represent a significant amount of trade between the U.S. and Mexico.Vehicle costs for American consumers could rise almost 4% if the tariffs are enacted.
The threat puts at risk the United States-Mexico-Canada Agreement, a trade deal that hasn’t yet been ratified by MexicoPresident Donald Trump’s surprise announcement that his administration will levy a 5% tariff on all Mexican imports starting on June 10 could create economic havoc for automakers and the agriculture industry, while raising costs for American consumers and businesses.
Mr. Trump said the percentage will gradually increase — up to 25% — “until the Illegal Immigration problem is remedied,” referring to the surge of Central American migrants trying to cross the U.S. border. The announcement, which comes while the Trump administration is also waging a trade war with China, wasn’t well received by Wall Street, with major stock indexes sliding more than 1% on Friday. “The latest tariff threat with Mexico was quite unexpected, as we’ve been hearing how well discussions have been going with both Canada and Mexico,” Ryan Detrick, senior market strategist for LPL Financial, said via email. “This is just the latest worry to put on the fire for investors. The big question at the end of the day though is can we really fight two trade wars at the same time?”‘Cars hit the hardest
Automakers’ stocks slumped on Friday, including Ford Motor and General Motors, reflecting the industry’s reliance on open trade between the two countries. Auto parts and vehicles manufactured in Mexico represent the biggest chunk of its trade with the U.S., totaling $93 billion last year.
In the 25 years since NAFTA, the U.S. auto industry has developed deep connections with its southern counterpart, with parts often crossing the border many times before ending up in a vehicle.Take the wires in your car. They connect power everything in a vehicle — from dashboard electronics to the engine ignition to power for windows. Substantially all the wire harnesses used in North America come from Mexico, with the remainder coming from China, said Peter Nagle, senior automotive economist at IHS Markit. And profit margins on these components are slim, which means “they would be hard-pressed to weather significant tariff increases,” Nagle said. And the impact goes beyond a few dollars’ increase. “Even if a tariff is only 5%, which is relatively manageable, you’ll have logistical problems,” Nagle said. “Right now it’s relatively open borders for commercial traffic. With the tariffs… you’ll have paperwork, logistical slowdowns, staffing concerns.”Detroit’s roots in Mexico
“Remember, 17% of the cars Detroit sells are built in Mexico,” Jack McIntyre, portfolio manager at Brandywine Global, said in an emailed note. On average, he said, the price of a new car might increase by $1,500 or more, leading to a drop in U.S auto sales, he noted. That would hit some automakers harder than others. Nearly one-quarter of Fiat Chrysler’s U.S. sales are sourced in Mexico, according to UBS analyst Colin Langan. For GM, that figure is about 16%. (Overall, 12% of U.S. car parts come from Mexico, he said.) Both automakers build their highly profitable full-size pickups in Mexico, compounding the tariff hit.Automakers have large percentages of foreign auto parts in their vehicles, sometimes more than half. About 44% of the parts used to manufacture the Chevrolet Silverado stem from Mexico, while another 10% is imported from other countries, for example. If tariffs reach 25%, as they are set to do on Oct. 1, it would raise car prices by 3.6%, Langan estimated.
