Unpacking the Unique Spain–Iran Relationship
As 2026 begins, the bilateral relationship between Spain and Iran stands as one of the most intriguing anomalies in global geopolitics. As a member of NATO and the European Union, Spain is theoretically aligned with the West. Yet in practice Madrid often adopts a middle path that is more moderate and pragmatic toward Tehran.
Spain’s stance is heavily shaped by the country’s collective memory. Prime Minister Pedro Sánchez has vigorously promoted the slogan “No to War”, a sentiment rooted in Spain’s trauma from involvement in the 2003 Iraq War.
In March 2026, tensions peaked when the Spanish government officially refused a US request to use joint military bases at Rota and Morón de la Frontera to launch air strikes against Iran. Madrid argued that unilateral military action without a UN mandate violates international law.
Despite international sanctions, economic ties between Spain and Iran remain in non-sanctioned sectors. Iran remains a major exporter of spices (notably saffron) and agricultural products to Spain. Conversely, Spain is an important supplier of pharmaceuticals and industrial technology to Tehran.
According to data from the Observatory of Economic Complexity (OEC) as of November 2025, Spain recorded a 156% increase in imports from Iran compared to the previous year, dominated by laboratory products and foodstuffs, indicating a lingering dependency amid political pressure.
Defence Minister Margarita Robles emphasised that bases on Spanish soil remain under Madrid’s sovereignty. Spain refused to participate in unilateral action lacking a solid international legal basis, to avoid broadening regional escalation in the Middle East.
Iranian President Masoud Pezeshkian praised Madrid’s move as a responsible stance. Iran regards Spain as one of the most rational partners in Europe that still respects sovereignty and multilateral dialogue.
The Spanish government views Iran as a key actor that cannot be ignored. Spain argues that balancing Iran and Saudi Arabia is essential to defusing Middle East conflicts, including resolving the Syria and Yemen crises.
Iran uses soft power through media such as HispanTV, a 24-hour Spanish-language news channel. While its presence is often debated in domestic Spanish politics, the channel serves as a diplomatic tool for Tehran to communicate its perspective directly to Spanish-speaking audiences.
Following the Taliban’s return to power in Afghanistan, Spain-Iran ties have intensified in humanitarian cooperation. Spain acknowledges Iran’s significant role in hosting millions of Afghan refugees. The two countries continue to coordinate on humanitarian aid and efforts to prevent drug trafficking into Europe.
Perhaps the biggest challenge for this unique relationship is the threat of an embargo from Washington. In March 2026, the White House threatened to halt all trade relations with Spain. However, Spain’s status as an EU member offers collective protection, since trade policy falls under the remit of the European Commission rather than individual member states.
Prime Minister Pedro Sánchez has firmed a stance against war in Iran, prioritising diplomacy and humanitarian concerns despite pressure from the United States.
