Goldman Sachs estimates that President Trump's proposed tariffs on eight European countries could dent real GDP by 0.1% to 0.2% across affected nations. The tariffs, announced recently, target Denmark, Norway, Sweden, France, Germany, the UK, the Netherlands, and Finland, with an initial 10% rate starting in February, set to rise to 25% in June. This move is linked to the US's ongoing efforts to purchase Greenland.

The potential economic impact varies by country. Germany, for instance, could see a hit of about 0.2% of GDP if the tariff is implemented as a 10% incremental reciprocal tariff, while the overall Euro area faces exposure worth 1% to 1.5% of GDP. The UK's affected exports would represent 1% to 2% of its GDP. These figures are on top of the 0.4% real GDP drag Goldman previously estimated from last year’s tariff increases.

Goldman also outlines potential EU retaliation measures, including stalling last year’s EU-US trade deal, imposing counter-tariffs, or activating the Anti-Coercion Instrument. These actions could create mechanical upward pressure on European inflation and prompt policy responses. The brokerage expects the UK to focus on diplomatic engagement rather than retaliation, mirroring its approach during recent trade negotiations.

Investors and business leaders should watch for the actual implementation of these tariffs and the EU's response. The economic fallout could be mitigated if countries reroute trade through EU nations not subject to the additional tariff, or exacerbated by adverse confidence or financial market effects.
