NATO Secretary General Mark Rutte will attend the World Economic Forum in Davos this week, scheduling bilateral meetings and a plenary on European defense. His visit coincides with U.S. President Donald Trump's planned speech, as global markets remain jittery over renewed threats of tariffs linked to Greenland.

The Greenland dispute has escalated, with Trump suggesting the U.S. could take control of the Danish territory. European leaders are now weighing a retaliatory 93-billion-euro tariff package and considering a powerful economic deterrent tool. This rift threatens to unravel the recent U.S.-EU trade agreement and strains the transatlantic alliance.

Rutte’s presence aims to manage fallout from the president’s rhetoric, which has already roiled stocks. Investors are watching for any breakthrough or escalation in Davos. The confrontation tests NATO’s cohesion at a time when geopolitical friction is increasingly influencing global markets and investment flows.
