Spain Has Closed Its Airspace to the US Military — and the Trade Consequences Could Be Severe

Quick Answer: Spain has closed its airspace to all US military aircraft involved in the Iran war, Defence Minister Margarita Robles confirmed on Monday. The move extends an earlier ban on US use of the Rota and Morón military bases. Donald Trump has already threatened to cut all trade with Spain in retaliation — a threat that, if executed, would constitute one of the most serious ruptures in transatlantic relations since the Iraq War.

What Spain Has Done

Spain’s position has hardened progressively since the US and Israeli strikes on Iran began on 28 February. Prime Minister Pedro Sánchez was among the first European leaders to condemn the war as illegal, describing it as “reckless and unjust.” His government then denied Washington access to the Rota naval base and the Morón air base in southern Spain — forcing 15 US refuelling aircraft to relocate to France and Germany — before Monday’s confirmation that the entire country’s airspace is now closed to US military operations in Iran.

“We don’t authorise either the use of military bases or the use of airspace for actions related to the war in Iran,” Defence Minister Robles told reporters. U.S. News & World Report Spain’s Economy Minister Carlos Cuerpo was equally direct, describing the US-led action as “a unilateral war that violates international law” and stating he expects trade relations with the US to remain unchanged — a confidence that appears to be tested almost daily.

Trump’s Trade Threat

Washington’s response has been characteristically direct. Trump threatened to cut off all trade with Spain following Madrid’s refusal to allow the bases to be used for Iran operations, calling Spain “terrible” and accusing it of wanting to “travel for free” on defence spending. euronews

The threat is not empty. The US is Spain’s largest non-EU export market. Spanish exports to the US — including automotive components, agricultural products, pharmaceuticals and industrial machinery — are worth approximately $17 billion annually. A full trade embargo, or even a significant tariff escalation, would hit sectors already under pressure from the energy shock driving stagflation fears across Europe. Spain’s economy is particularly exposed given its energy import dependency and its reliance on external demand to sustain growth.

The EU Dimension

Spain’s stance creates a difficult position for Brussels. The EU as a bloc has called for de-escalation and civilian protection without formally condemning the US-Israeli military action. France and Germany have allowed US aircraft to use their airspace. The UK has offered Fairford Air Base in Gloucestershire. Spain stands almost alone among major NATO members in taking a position this direct.

That divergence matters. If Trump moves to impose trade measures on Spain specifically — rather than tariffs on the EU as a whole — it creates the kind of bilateral pressure that is designed to fracture European solidarity. As the EU has already been navigating a broader tech and trade confrontation with Washington, the Spain episode adds another pressure point to a relationship already under severe strain.

What Comes Next

Spain’s Foreign Minister José Manuel Albares, when asked whether Madrid feared US retaliation, reportedly answered simply: “Why should we be afraid?” It is a bold position — but one with real economic exposure behind it.

The immediate military impact of the airspace closure is limited. US bombers transiting to Iran cross the Strait of Gibraltar rather than entering Spanish airspace directly. The strategic significance is more symbolic and political: a NATO ally is publicly refusing to facilitate a US military operation and willing to absorb the economic consequences.

As the Iran war enters its fifth week with oil at $116 and global markets pricing in a protracted conflict, Spain’s decision signals that the geopolitical fractures within NATO are deepening — and that the trade consequences of this war may eventually extend far beyond energy prices.
