Tariffs' economic impact: prices, trade, growth, and central bank policy

Recent U.S. tariff increases have injected significant uncertainty into the global economy.

Academic literature and model simulations indicate that tariffs ultimately raise U.S. consumer prices and reduce output, despite limited immediate effects.

For the euro area, higher U.S. tariffs are projected to be contractionary, mainly due to reduced external demand.

The inflationary impact for the euro area remains uncertain, influenced by potential higher global costs, euro appreciation, and trade diversion.

The study highlights that EU retaliation would exacerbate the macroeconomic downturn, leading to deeper GDP declines across the Atlantic and lower inflation through weakened aggregate demand.

This provides analytical support for the EU's current restrained approach, even without considering political-economy factors.

The initial ambiguity surrounding tariff levels and responses unsettled global markets, straining transatlantic relations.

Academic literature suggests an accommodative monetary policy response to tariffs, provided inflation expectations remain anchored.

This involves tolerating gradual tariff-induced price increases and accommodating real activity weakness, as tariff shocks reduce real income and tighten financial conditions.

For the ECB, the ultimate impact of U.S. tariffs on euro area inflation is uncertain, depending on conflicting forces from demand, supply, exchange rates, and trade policy uncertainty.

Short-term, disinflationary pressures might dominate due to euro appreciation and trade diversion.

Long-term, a fragmented global economy could create sustained upward pressure on inflation from higher import costs and reduced capacity.

However, weaker productivity and geopolitical uncertainty might dampen aggregate demand.

The net long-term inflation outcome hinges on these opposing forces.
