Iran's IRGC Declares Strait of Hormuz 'Completely Closed' After Alleged Mine Strikes on Oil Tankers, While Rial Hits Record Low Against US Dollar

July 18, 2026 · 🔴 Risk: High

⚖️ Two accounts of the same story

Where sources agree

Multiple sources confirm escalating US-Iran military conflict, with the Strait of Hormuz as a key flashpoint. There is a broad consensus on the severe distress of the Iranian economy, characterized by record inflation and currency depreciation, and negative IMF economic projections. The IRGC's claim of closing the Strait is widely reported.

Where sources differ

While the IRGC claims the Strait of Hormuz is 'completely closed', earlier reports from July 16, 2026, indicated that commercial traffic continued at reduced levels, utilizing ship-to-ship transfers near Oman. Iran's Oil Minister also asserted on July 14, 2026, that oil exports are ongoing despite US sanctions, which contrasts with the broader narrative of severe export restrictions due to the conflict and sanctions.

The declared closure of the Strait of Hormuz, a critical global oil chokepoint, coupled with escalating US-Iran military conflict and a record depreciation of the Iranian rial, presents an immediate and severe risk to regional stability and the global economy.

📌 Key developments

Iran's Islamic Revolutionary Guard Corps (IRGC) claimed on July 17, 2026, that two oil tankers struck mines in the southern Strait of Hormuz, declaring the waterway 'completely closed' and warning commercial vessels against entry.
The Iranian rial depreciated to a new record low against the US dollar, reaching 1,918,000 rials on the open market on Friday, July 17, 2026, surpassing its previous high of 1,900,000 rials recorded on May 4.

Iran's Oil Minister Mohsen Paknejad stated on July 14, 2026, that the country's oil exports are continuing without interruption despite the US cancellation of waivers, attributing this to established anti-sanction mechanisms.
Inflation in Iran reached an all-time high of 88.60% in June 2026, up from 83.90% in May 2026, with food inflation skyrocketing by almost 134% in the month ending June 21, 2026.

💡 Why it matters

The closure of the Strait of Hormuz threatens a substantial portion of global oil and gas shipments, risking severe structural damage to the global economy if not resolved quickly, as warned by the IEA. For Iran, the escalating conflict and currency collapse exacerbate an already dire economic situation, increasing import costs, fueling hyperinflation, and severely eroding citizens' purchasing power.
