President Trump is applying the brakes to the profit engines of global automakers.

Trump said Wednesday the US will impose 25% tariffs on imports of cars and car parts, to take effect on April 3. The measures will apply to both finished cars and trucks.

“This will continue to spur growth that you’ve never seen before,” Trump said from the White House about the new tariffs.

Investors and Wall Street don’t appear to agree, given the response early on Thursday in stock markets and analyst takes.

The tariffs could raise the cost of production for automakers and stunt demand through higher prices for consumers. About half of all vehicles sold in the US are imported.

Shares of the Big Three US automakers, which build vehicles abroad, dropped in premarket trading on Thursday. General Motors (GM) and Ford (F) were down 7% and 3%, respectively, while Europe-focused Stellantis (STLA) fell 2%.

“In reality, these [US] carmakers would likely price vehicles much higher, which would result in lower volumes and a lower negative impact to earnings,” RBC Capital Markets analyst Tom Narayan said.

Interestingly, Tesla (TSLA) shares rose 1%. The EV maker, headed by Trump’s DOGE leader Elon Musk, makes the bulk of its models in the US.

Meanwhile, Japanese automakers Toyota (TM) and Honda (HMC) US-listed stock slid 2% each. Europe’s Ferrari (RACE) declined 1%.

Shares in auto-parts suppliers also slipped, with Magna International (MGA) and Dana (DAN) each down by 2%.

Longtime auto journalist Jamie Butters said on Yahoo Finance’s Market Domination (video above) that Ford executive chairman Bill Ford and GM CEO Mary Barra will be meeting with Trump within the week to discuss the new tariffs.

Here is some of the early analysis from Wall Street of Trump’s new auto tariffs.

“We calculated that the maximum negative impact of a 25% tariff on Japanese automakers in aggregate to be ¥4.46 trillion. Among particular automakers, we also estimated that, in light of their high ratios of imports from Canada, Mexico, and Japan, as well as the size of their overall earnings on autos, Nissan Motor would be the most heavily affected company, followed in order by Mazda Motor, Subaru, Mitsubishi Motors, Honda Motor, and Toyota Motor.

“There could be a near-term correction in sector share prices in the wake of the 25% tariff announcement, but we can also envision the market pricing in a scenario of the tariff being negotiated lower. Realistically, the imposition of a 25% tariff would inevitably put upward pressure on auto prices, so in our view, a tariff this high probably cannot be maintained.
