Iran Recloses Strait of Hormuz 72 Hours After Ceasefire Deal, Reviving Oil Shock Risk
3 articles · Updated · The Conversation · Jun 25
Summary
Iran’s military said it shut the Strait of Hormuz again within 72 hours of the June 18 U.S.-Iran memorandum, undercutting the ceasefire reached after months of conflict.
The move follows Iran’s use of the strait closure since February to disrupt global energy supplies, stoke Western inflation and pressure Washington into negotiations.
Tehran tied its latest threat to Israeli strikes on Hezbollah, exposing a core flaw in the deal: any Israeli action in Lebanon can trigger renewed pressure on oil flows.
That leaves Trump facing domestic political risk from higher gasoline prices and Israel resisting any framework that limits retaliation, making the agreement look more like a temporary pause than a durable settlement.

The 2026 Strait of Hormuz Crisis: Largest Oil Supply Shock in History and the Collapse of US-Iran Diplomacy
Overview
On June 20, 2026, intense military clashes erupted in southern Lebanon as Israeli airstrikes killed at least 16 people, including children, following a barrage of over 50 projectiles launched by Hezbollah at Israeli forces. This escalation heightened regional tensions and directly challenged the interim agreement reached between the United States and Iran just days earlier, which called for an immediate end to military operations. The ongoing violence in Lebanon undermined the fragile ceasefire, contributed to Iran’s decision to reclose the Strait of Hormuz, and triggered a global oil supply shock, highlighting the deep interconnectedness of regional conflict and worldwide economic stability.
