Donald Trump’s appearance at the World Economic Forum in Davos rattled investors as he announced new tariffs tied to his Greenland ambitions. The former president’s remarks unsettled the EU and NATO alliance, hinting at a shift in trade policy that could reshape European markets and defense spending.

By targeting key EU exporters, the proposed tariffs could trigger a sell‑off in European stocks, especially in the shipping and defense contractors sectors. Analysts warn that a sudden tariff hike would pressure supply chains and inflate costs for NATO members, potentially prompting a diplomatic review of the alliance’s trade safeguards.

Investors will watch the EU’s next steps closely, as Brussels may counter with retaliatory measures that could widen the tariff war. Meanwhile, defense firms eye potential contracts to fill gaps left by shifting alliances. Market watchers expect the next World Economic Forum session to clarify the scope and timing of these new duties.
