• The Strait of Hormuz could fully reopen 30 days after a US-Iran agreement, according to a Nikkei report citing a source.
  • The reopening would restore free and safe navigation for all countries after months of de facto shutdown.
  • The framework being discussed includes security guarantees, sanctions relief, and nuclear-related concessions.

Iran has signaled it will open the Strait of Hormuz to commercial shipping 30 days after reaching a deal with the United States to end hostilities, according to a Nikkei report citing a source familiar with the matter. After an agreement, ships from all countries would be able to navigate freely and safely, just as they did before the de facto shutdown, the source said.

The development marks a potential breakthrough in efforts to de-escalate Gulf tensions that have roiled global energy markets since February 2026. The framework under discussion includes suspension of maritime restrictions, limited sanctions relief, and a broader negotiation on nuclear issues, according to people familiar with the talks. However, the framework has not yet been formally approved.

The reopening would be closely tied to security assurances for shipping and crew safety, with international maritime authorities emphasizing that freedom of navigation in international straits should not be used as leverage in conflicts. The Strait of Hormuz is a critical chokepoint for global oil supplies, and its closure has sent shockwaves through energy markets, boosting freight rates and insurance costs.

Market observers have framed the potential reopening as highly consequential. “A reliable reopening would stabilize oil flows and dramatically reduce shipping costs,” one analyst said. But the exact timing and terms remain contingent on final agreements and verifiable security guarantees.

The international community, including the UN and coalition partners, has pushed for a durable settlement that keeps Hormuz open. “We have a constant dialogue with all parties to ensure safe passage for neutral and commercial vessels,” a diplomatic source said, speaking on condition of anonymity.

Iranian officials did not immediately respond to requests for comment. The US State Department declined to comment on the report.

Correction: An earlier version of this article misstated the timeline for reopening. The source cited by Nikkei specified 30 days within an agreement, not 30 days from the report date.
