US and European stock futures tumbled while safe-haven assets surged after President Donald Trump threatened new tariffs on the UK and EU. The move, tied to his pursuit of a Greenland takeover, has spooked investors and prompted swift market reactions. The threat compounds existing trade tensions and geopolitical uncertainty.

EU leaders are convening an emergency meeting to address Trump's tariff threat, signaling a potential escalation in transatlantic trade disputes. This confrontation could disrupt supply chains and corporate earnings for major European exporters. The situation also overshadows other geopolitical developments, including the formation of Trump's 'Board of Peace' for Gaza.

Separately, Saudi Arabia is finalizing a new military coalition with Somalia and Egypt, a move that could shift regional security dynamics. Meanwhile, the US is intensifying criticism of South Africa following joint naval drills with Iran. These events highlight a fragmented global landscape where economic and military alliances are being rapidly redrawn.
