Trump heads to Davos, reiterates Greenland tariff threat despite risks for US economy

President Trump’s push to pressure European allies over US control of Greenland is rapidly morphing from geopolitical theater into a tangible new source of economic risk for the United States.

In recent days, the president has threatened tariffs on eight European nations that resist a deal over Greenland, on top of earlier vows to impose a 25% duty on countries that do business with Iran.  Global markets have already shown signs of strain, with stocks sliding and the dollar weakening after he pledged new levies on European partners over the Greenland dispute.

As Trump heads to the WEF meeting in Davos, the episode reopens a playbook many hoped to close after the last round of trade wars. But this time the confrontation targets America’s closest security and trading partners and is unfolding against a more fragile macro backdrop.

European Union diplomats are scrambling to dissuade Washington from moving ahead with the tariffs, even as they sketch out unprecedented retaliatory measures should the duties be imposed.  European leaders are also debating their own “trade bazooka” response, underscoring how quickly the dispute could escalate into a full-blown transatlantic trade war.  

At the same time, international institutions are warning that trade tensions are once again among the main threats to global growth. The IMF has highlighted tariff conflicts as a key reason it now expects global growth to slow to about 3.1% in 2026.  It has also cautioned that trade frictions and a reversal of the artificial-intelligence-driven market boom are central downside risks.

For the US economy, the immediate channel of impact would be higher import costs on European goods and potential counter-tariffs on American exports. Key sectors such as autos, aerospace, industrial machinery and pharmaceuticals could face margin pressure and market-share losses if the European Union targets iconic US brands in response.

Even if underlying demand softens, higher goods prices and renewed supply chain uncertainty could keep headline inflation stickier than policymakers anticipate, limiting the Fed’s scope for cuts and keeping real borrowing costs elevated for households and firms.

Episodes of tariff anxiety have tended to produce a familiar pattern: equity volatility, sector rotations away from trade‑sensitive exporters, a bid for Treasuries and safe‑haven assets, and oscillations in the dollar.  If the standoff intensifies into a prolonged dispute, asset allocators may need to revisit assumptions on correlation, hedging and country risk.
