Trump tariff threat rattles markets and forces officials to recalibrate

Markets and policymakers continued to digest fresh trade uncertainty after President Donald Trump threatened sweeping tariffs on goods from multiple European countries unless the U.S. is allowed to purchase Greenland.

The threat prompted concerns about economic blowback, including volatility in equities and the risk that companies delay investment or hiring as they wait for clarity on trade rules.

In the U.K., the episode disrupted planned business appearances, underscoring how quickly geopolitical brinkmanship can spill into financial sentiment.
