Report: Tariffs Could Lead To Halt In Auto Production

Automotive intelligence firm S&P Global Mobility is predicting that if President Donald Trump's proposed tariffs lead to a trade war, there's a 50 percent chance that the auto industry could enter a long period of disruption.


According to The Detroit Free Press, the firm has put out three possible scenarios that could play out, depending on how the trade wars go. In one, production could drop by 20,000 vehicles per day just a week from yesterday.

From S&P via Freep:

"Although some contend that tariffs on the auto industry may boost U.S. manufacturing, only GM, Ford and Stellantis have excess capacity to increase U.S. production, and automakers are not likely to be able to make such a change quickly or cost-effectively," S&P Global's report said. "A production shift would also require suppliers to relocate."

S&P says that the chance of a quick resolution to the tariff issues is only 30 percent.

S&P further points out that the auto industry doesn't like to invest without long-term stability. Tariffs aren't the only thing causing uncertainty that could delay investment and the development of future vehicles -- there is also confusion over what may happen with fuel economy and emissions regulations.

Again from S&P via the Freep:

"With tariffs now imposed on Canada and Mexico, we expect significant disruption in the region. S&P Global Mobility sees potential for North American production to drop by up 20,000 units per day within a week," the report stated. "We now expect that the tariff posture, messaging and coverage through 2025 will be erratic, placing (automakers) and suppliers’ mid- or long-term vehicle and facility planning in a virtual gridlock."

For now, Trump has enacted 20 percent tariffs on China and put 25 percent tariffs on Canadian and Mexican products, but exempted automakers that are part of the USMCA until April 2. He's also put 25 percent tariffs on steel and aluminum coming in from all countries. Canada and the European Union have hit back with tariffs on American goods -- the EU, for example, is tariffing motorcycles.

China has retaliated, too, with tariffs on chicken, beef, pork, soybeans, fruit, wheat, and corn.

For a vehicle to be USMCA compliant, it must have 75 percent of its content sourced from Canada, Mexico, or the U.S. Additionally, 40 percent of core parts and 70 percent of steel and aluminum must be sourced from the region, and wage requirements also must be met.

Given the complexity of supply chains, it's hard to say exactly which cars are compliant. S&P says Canadian-built vehicles with engines and transmissions sourced from USMCA countries are the most likely to comply. That means Stellantis, General Motors, and Toyota are the most likely to comply. Honda imports some of its transmissions, and Ford also might not be compliant. S&P says Nissan likely is, as is Mazda, despite importing some transmissions. Hyundai/Kia are likely to be compliant, but it's harder to tell with Volkswagen. BMW and Mercedes-Benz are unlikely to be compliant because they source engines and transmissions from Europe.

S&P's three scenarios are this: quick resolution, extended disruption, and tariff winter. That last one means tariffs would continue for a long time and cars would cost more, either because of the tariffs or because automakers would shift some production back to the U.S. and incur higher labor costs. The costs of tariffs or more-expensive labor would be passed on to the consumer. In this last scenario, sales would tumble about 10 percent in the U.S.

S&P does expect some production to shift back to the U.S., either because of the tariffs or because an automaker had already decided to build a certain model in the States but had yet to announce it. Still, it would take time to shift production and sales would likely drop before that can happen.

    I set out one egg this morning instead of two (economists call this the 'substitution effect' but I wouldn't know about that, just look at the region I am from). But then I went and fired up the truck and did some work with a shovel and a broom, no breakfast yet. My grandparents lived through the Great Depression, I think I probably have it worse than them now. I am basically at Valley Forge levels of hardship, maybe. Can we bring back FDR?

    (I would do some all caps or bold or underlining but I am so very tired.)

      Nothing happened. I am building a chicken coop. Back to the USSR

    Lots of good land in Alabama for more auto factories! I’m all for tariffs moving manufacturing back to the US.


    the fact an EV startup (relatively speaking) makes autos in USA for USA successfully and the legacy 3 can’t says there’s a problem with the failing brands - perhaps the decision to layoff here and hire there wasn’t so wise.

  • The Ayatollah of Rock n Rolla If the new REO actually happens, and it happens roughly where their target price sits, but at least below $30k, I think that is a great inexpensive truck that would solve the truck needs of the vast majority of current truck buyers.As for cars...we need CARS. Not stupid SUVs. Not ugly crossover blobs. CARS. Coupes, sedans, wagons. Start building something midsized, and make the price point in the mid 30s or lower. AWD optional. And yes, I know Toyota, Honda, and Hyundai/Kia still make sedans. But GM, Ford, and Chrysler/Stellantis need to get on the ball and bring out some competition.
  • 3-On-The-Tree My C6 with the LS3 got over 30 mpg on the highway in 6th gear on cruise control doing 80-85.
  • KwikShiftPro4X On Kijiji this would be $3000 as-is, where-is. Vintage! Rare! I knows whats I got!
  • SCE to AUX KBB says that the ATP of new vehicles was $50,526 in September. As a group, buyers afforded that much, but we know that some (up to 6%) will default. Deducting 6% from that ATP, we get $47,494.So anything lower than that is 'more affordable', and anything higher than that is 'less affordable'.
