The European Union will suspend ratification of its U.S. trade deal on Monday as Brussels seeks clarity on Washington's tariff plans. Main political groups in the European Parliament confirmed the freeze comes after President Trump announced 15% global tariffs following the Supreme Court's rejection of his emergency powers approach.

The White House initially proposed 10% tariffs but Trump raised the figure to 15%. Analysts warn Trump could create a "de facto perpetual tariff instrument" by allowing current levies to expire and declaring new emergencies. The EU represents $303 billion in U.S. imports, accounting for 20.2% of total American imports.

European stocks fell to session lows amid the uncertainty. The trade agreement, negotiated last summer, would have established reciprocal tariff reductions between the economic blocs. Lawmakers previously paused ratification after Trump's threats to take over Greenland.

"There is no other option but to postpone the approval process until the situation becomes clearer," the European People's Party's lead negotiator told Bloomberg. EU ambassadors and the parliament's trade committee chair both called emergency meetings to reassess the deal.
