Strait of Hormuz stays severely disrupted despite the strike pause; JMIC threat level held at SEVERE (Update 074)
More than a week into a fragile US-Iran pause in strikes, the Strait of Hormuz has not returned to normal operations. Traffic remains far below pre-war levels — fewer than 10 commodity ships transited on the latest monitored day, against roughly 100 on a typical pre-war day (CNN shipping data). The maritime threat level has not been lowered: the Combined Maritime Forces' Joint Maritime Information Center, in its most recent numbered advisory (Update 074, 21 July), continued to assess the regional threat as SEVERE, and US MARAD Maritime Alert 2026-001A remains in force, advising vessels to avoi

US and Iran pause strikes for a second straight day; no formal ceasefire and Iran says no current negotiations
After nearly two weeks of fighting that shattered the mid-June 60-day ceasefire, the United States and Iran both paused their strikes around 25-26 July. President Trump said the US halted attacks 'at the request of the Iranian regime' and warned Washington would resume unless a new ceasefire deal is reached; Iran says it is not currently negotiating with the US (NPR, CNN). The lull has stopped the daily strikes on shipping but is not a formal ceasefire, no agreement has been signed, and the Strait of Hormuz remains severely disrupted with transit far below normal.

Two Dynacom tankers — Kavomaleas and Acheloos — struck by projectiles off Oman near the Strait of Hormuz
Greek shipping company Dynacom Tankers said two of its managed vessels were hit by projectiles of unknown origin on Monday 20 July while transiting the US-facilitated southern Hormuz corridor off Oman. The Malta-flagged Panamax tanker Kavomaleas was struck by two projectiles, causing a fire in its engine room and forcing the crew to abandon ship; the Liberian-flagged Acheloos was also struck. UKMTO reported a vessel on fire about 8 nautical miles northwest of Oman's Kumzar, with no environmental impact; all crew were safely located by Omani authorities and taken ashore (Reuters, gCaptain, Lloy

Maritime threat level held at SEVERE (JMIC Update 072); US declares naval blockade of all Iranian ports
The Combined Maritime Forces' Joint Maritime Information Center, in its Advisory Note Update 072 (16 July), assessed the regional maritime threat level as SEVERE, with hostile activity observed across the Gulf, Strait of Hormuz and Gulf of Oman and deliberate hostile action considered highly likely. The risk was further elevated by the US announcement and initiation of a naval blockade of all Iranian ports and coastal areas, effective 14 July 2026 at 2000Z (JMIC Advisory 015-26). US MARAD Maritime Alert 2026-001A advises vessels to avoid the region where possible, maintain at least 30nm separa

Iran's IRGC strikes Cyprus-flagged container ship GFS Galaxy in the Strait of Hormuz; crew member missing, US launches third round of strikes

UKMTO reported the incident about 9 nautical miles off the coast of Oman, with a fire at the rear of the ship.

No group claimed responsibility and the weapon was unconfirmed (one maritime-security source assessed a likely drone); attribution is not established.

Authorities assess this as strategic messaging rather than an operational closure: JMIC Advisory 009-26 (18 Jun) rates the Regional Threat Level 'Moderate' (down from Substantial/Severe) and judges the strait open, with no independent confirmation of a physical closure or new vessel attacks; the U.S. (CENTCOM/Energy Secretary) reports dozens of ships still transiting via the southern Omani route.

Iran imposes mandatory PGSA permit and 'Hull War Voyage Insurance' for Hormuz transit

The insurance is free during a ~60-day window expiring around 17 Aug 2026; thereafter PGSA-only coverage — itself sanctioned — could make Western commercial transit categorically impossible without sanctions relief.
