Capital Economics warns that President Trump's proposed tariffs on goods linked to Greenland could slash UK GDP by 0.30-0.75%. The economic research firm specifically highlighted risks to the nation's car and pharmaceutical manufacturers, which would face immediate competitive pressures if the levies are enacted.

The analysis suggests the long-term geopolitical fallout could outweigh the direct economic hit. Such trade friction might inadvertently push the United Kingdom closer to the European Union on goods trade, altering a post-Brexit alignment. This comes as UK industry already grapples with broader cost and demand challenges.

Investors should watch for retaliatory measures and shifts in supply chains. The proposed tariffs, part of a broader Trump trade agenda, could recalibrate transatlantic business relationships. For UK manufacturers, the prospect adds another layer of uncertainty to an already strained operating environment.
