Trump Threatens 25% EU Auto Tariff, Risking New Trade War
US President Donald Trump’s threat to increase tariffs on European Union-made cars and trucks to 25% from 15% sent a chill through the automotive sector, raising the prospect of a renewed trade conflict between the world’s two largest economic blocs.
"Based on the fact the European Union is not complying with our fully agreed to Trade Deal, next week I will be increasing Tariffs charged to the European Union for Cars and Trucks," Trump wrote on the social media platform Truth Social, adding that manufacturers who build in the U.S. would face no tariff. The European Commission rejected the assertion, stating it is implementing the agreement in accordance with standard legislative procedures and would reserve all options to defend its interests.
The market reaction was swift and negative. The pan-European STOXX Europe 600 Automobiles and Parts index fell 0.7%, making it the worst-performing sector in the region. German automakers were hit hardest, with Continental AG sliding 5.4%, Porsche AG down about 3%, and BMW AG, Mercedes-Benz Group AG, and Volkswagen AG all dropping between 2.5% and 3%.
The move injects significant uncertainty into a transatlantic trade relationship that was already fragile. For an auto industry grappling with the costly transition to electric vehicles, rising competition, and elevated energy costs, the timing of a potential multi-billion dollar tariff hit could hardly be worse, threatening to either increase prices for US consumers or compress already squeezed profit margins.
A Fragile Agreement Unravels
The conflict stems from a trade deal struck last August. Under the agreement, Washington lowered its global auto tariff from 25% to 15% for European vehicles. In return, the EU committed to scrapping duties on some American industrial goods and accepting U.S. vehicle safety and emissions standards. However, the EU’s lengthy legislative process, which saw lawmakers only advance the necessary legislation in March with full ratification not expected before June, appears to be the trigger for Trump's threat. His administration views this delay as a form of non-compliance, a justification for potentially voiding the agreement.
"It appears that President Trump is angry that the removal of tariffs on US industrial goods that was agreed last September after being proposed in July 2025 has yet to pass through the EU’s lengthy legislative process," Bernstein analysts said in a note.
Counting the Costs for Germany
The economic stakes are highest for Germany, whose economy is heavily reliant on its automotive industry. According to a recent analysis by the Kiel Institute for the World Economy, a 25% US tariff on EU cars and trucks could slash Germany's gross domestic product by nearly EUR 15 billion. The institute, which forecasts Germany's economy will grow by a sluggish 0.8% this year, warned that long-term output losses could approach EUR 30 billion, severely hitting the nation's growth.
Bernstein analysts estimate the earnings headwinds would be "meaningful," with potential 2026 automotive EBIT hits of 12.1% for BMW, 14% for Mercedes, 16% for Porsche, and 21% for Stellantis if the full tariff is passed on.
Broader Risks in a Strained Global Economy
This potential trade dispute does not exist in a vacuum. It adds another layer of pressure on a global economy already contending with spiking energy prices and shipping disruptions stemming from the war in Iran. As Eurogroup President Kyrakos Pierrakakis noted, the confrontation is "quite unnecessary, and quite unfortunate" given the other challenges weighing on the European economy. The EU has made it clear that "all options are on the table," signaling that retaliatory tariffs on US goods are a distinct possibility, which would escalate the conflict and broaden its economic impact.
