March 27 (Reuters) - U.S. President Donald Trump said late on Wednesday the United States will effectively charge a 25% tariff on all cars not made in the country and that the new duties on cars and light trucks imported into the United States will be permanent.

Shares of General Motors ( GM ) and Ford fell in extended trade after Trump's announcement. Auto shares slid in South Korea and Japan, wiping out roughly $16.5 billion from transport stocks in Tokyo, according to LSEG data.

Europe was braced to sell with the euro at three-week lows and German DAX futures down 0.8%.

"There are a lot of layers here. However, I think the big concern is that not only will these tariffs be disruptive and economically harmful, but it indicates that the Trump administration's shake-up of global trade won't necessarily end with next week's April 2nd announcement of reciprocal tariffs, as previously hoped. This potentially drags out trade uncertainty even longer and raises the question of how radical a change to the global trade order is Trump trying to bring about."

"Trump's auto tariff probably has a bigger impact on the EU compared with Chinese carmakers. The levies on Chinese autos have been hiked up already, and they have relatively limited exposure to the U.S. market anyway. Also, his comments about the TikTok deal are giving people hope that there's room for negotiations.

"It now looks like he's more aggressive toward other markets instead of focusing all his efforts on China, so that could somehow help cushion the sentiment for China and Hong Kong."

"It is sort of anticipated. It is just a question of the timing... so maybe the market has sort of factored it in. The other aspect is investors assume he may backtrack a little bit, maybe that's why the market has become a little less responsive.

"With sentiment being so much more negative now, it's hard for negative news to have a big impact than it was several months ago."

"The auto tariffs represent a significant expansion of Trump's trade war. It also risks disrupting operations for U.S. automakers, which are highly integrated to supply chains in Mexico and Canada.

"Trump's latest actions will probably make cars more expensive for U.S. consumers already worried about inflation and could amplify recession worries. The tariffs may not only raise the prices of foreign-made cars in the U.S., even U.S.-made cars could see price increases if supplies and parts are affected by the levies.

"Retaliation from countries that have been affected by the latest auto tariffs could worsen the situation for U.S. consumers and automakers and fuel further concerns about inflation and the outlook for the U.S. economy."

"I've been kind of suspect on all the tariff talks in terms of what is going to last, what is a negotiation, what is going to be pulled at the last minute. My initial reaction was this tariff might have some legs."

"There's probably going to be some exemptions or modifications for some of the U.S. automakers... I could see the U.S. automakers getting some exemptions based on their supply chains. But I think he may want to see how this works out as opposed to stopping it in two or three days. That's my initial reaction, that this particular tariff might have legs in terms of its longevity."

"These auto tariffs are likely on top of other tariffs on steel, aluminum, copper and the impending reciprocal tariffs to be announced on 2nd April. It's hard not to interpret this as anything but a cue for higher prices and lower growth with a soft landing becoming more complicated. Countries most exposed to the new auto tariffs are Slovakia, Mexico, South Korea and Japan. Keep an eye on stocks of car makers, the Korean won and Mexican peso."
