in

The United States and Iran have reached an agreement on a peace treaty, and the Strait of Hormuz will officially open after the signing of the agreement. The reopening of this vital global energy shipping route will have a significant impact on global shipping and energy markets.

Opening Time and Agreement Background

Signing Arrangements: The text of the Islamabad Memorandum of Understanding between Iran and the United States has been finalized, and the formal signing ceremony will be held in Switzerland on June 19, 2026.

Agreement Content: Both sides announced an immediate and permanent cessation of military operations on all fronts, including Lebanon. The agreement explicitly states that Iran will not possess nuclear weapons. US President Trump has authorized the free opening of the Strait of Hormuz and lifted the relevant US naval blockade.

Specific Opening Arrangements

Opening Pace: The Strait of Hormuz will open immediately after the signing of the agreement. The overall opening will be carried out in phases. The first phase will begin mine clearance work and the lifting of the US blockade, ensuring that the shipping route is restored to its pre-war state within 30 days. Trump stated that the opening will be achieved “very quickly.”

Traffic Rules: According to the rules of the previous conditional opening phase, only civilian merchant ships are allowed to pass; military vessels are prohibited. All ships must follow the coordinated routes designated by Iran and coordinate with the Iranian Islamic Revolutionary Guard Corps.

Background and Impact

Strategic Value: The Strait of Hormuz handles approximately one-quarter of the world’s maritime oil trade, as well as a large volume of liquefied natural gas and fertilizer shipments, making it a core strategic node in the global energy system.

Market Impact: This news has already driven a significant rise in the shipping sector and will alleviate global energy supply pressures. International crude oil futures prices have shown a marked decline, and global stock markets will also gain some breathing room from the adjustment pressure.
