Morgan Stanley analysts argue European equities have "limited tactical downside" from President Trump's tariff threats over Greenland. They estimate only 2.2% of MSCI Europe index revenues are directly exposed to the proposed 10% duties on eight EU nations. Roughly 10% of the index's weight involves companies with over 10% revenue exposure, making the impact idiosyncratic rather than broad-based.

The tariffs are a negotiating tactic tied to the U.S. bid to purchase Greenland from Denmark. Brussels is preparing an emergency summit to consider retaliatory measures, including tariffs on €93 billion of U.S. imports and the "Anti-Coercion Tool." This crisis casts serious doubt over a newly forged transatlantic trade pact, with EU officials suggesting they cannot finalize it under this threat.

A Supreme Court ruling on the legality of Trump's tariff authority under IEEPA could arrive this week, potentially invalidating the levies. Should that happen, new legal justification for the Greenland-specific tariffs would be uncertain. Morgan Stanley maintains an overweight rating on European defense stocks, anticipating continued diversification flows into the sector as Europe reassesses its security posture.
