The plan seeks to guarantee freedom of navigation in the Strait of Hormuz in exchange for a calibrated suspension of the secondary sanctions weighing on the Iranian energy sector. This regional initiative arises after weeks of maritime hostilities that drove crude oil prices to critical levels and threatened the security of 20% of the global oil supply.

The document proposes the creation of a multinational monitoring mechanism in the strait, composed of regional navies and neutral observers, to replace the current confrontational deployment between the U.S. and Iranian fleets. Simultaneously, a gradual return of Iran to the international banking system is proposed for transactions linked exclusively to humanitarian goods and energy. Both the White House and the Supreme Council of Iran have initiated the technical review of the proposal, marking the first tangible sign of detente in the last three years.

Implications for energy security and the external sector

The diplomatic offensive led by Riyadh and Abu Dhabi confirms a paradigm shift: Gulf monarchies are prioritizing their own operational stability over the containment policies of external powers. For the Spanish energy sector, this pact represents an immediate reduction in the risk premium of Brent prices. Companies such as Repsol or Cepsa, with high exposure to international volatility, find a framework of greater operational predictability. Furthermore, the normalization of the Strait of Hormuz ensures the continuity of liquefied natural gas supplies from Qatar, a critical provider for the Spanish gas system.

The economic reopening of Iran, conditioned on the lifting of sanctions, opens a window of opportunity for Spanish engineering and infrastructure firms. Companies with prior experience in the region could access contracts for the modernization of oil fields and energy transport networks, which have been paralyzed for a decade. Nevertheless, political volatility in Washington and conservative factions in Tehran necessitate maintaining strategic caution. Spanish companies must monitor implementation schedules to avoid accidental regulatory non-compliance. The current scenario favors medium-term entry planning but requires rigorous due diligence given the fragility of the commitments made.
