US stock futures plunged the most since November, reacting to President Trump's weekend remarks about Greenland's future. The rhetoric revived fears of a trade war with the European Union, sending a jolt through equity markets ahead of the Monday open. Investors are now pricing in renewed geopolitical risk.

Trump's comments about acquiring Greenland, a Danish territory, have reignited transatlantic tensions. The prospect of a U.S.-EU trade conflict threatens to disrupt supply chains and corporate earnings. This follows years of tariff disputes that have already weighed on global business investment and market sentiment.

Market participants will closely watch the administration's next moves and any official response from Copenhagen or Brussels. A prolonged dispute could pressure multinational stocks and the dollar. For now, the swift futures reaction underscores how quickly political headlines can override fundamental data in today's interconnected markets.
