Hormuz Reopens in Bursts as Tanker Attacks Keep the Trade Lane on Edge

The last 48 hours turned the Strait of Hormuz into a mixed signal for shipping and energy markets. Some oil is still moving, and U.S. officials pointed to a strong Monday flow through the waterway, but the vessel picture remains thin, volatile and dangerous. Tuesday’s commodity-vessel count fell back to four, two Saudi-loaded VLCCs were hit near Khasab during an outbound transit, Bahri confirmed two seafarer deaths aboard Sidr, and Iran’s Revolutionary Guard claimed two more oil tankers hit mines while using what it called an unauthorized route. At the same time, U.S. strikes targeted Iranian maritime and mine-laying capabilities, Iran retaliated against regional U.S.-linked targets, Iranian crude exports remain largely stalled, and LNG cargoes from Qatar and the UAE are being handled through unusual ship-to-ship transfers outside Hormuz. The strait may not be fully closed, but it is not functioning like a normal commercial corridor.

Ship Universe Hormuz Watch

Operator Impact Snapshot

Traffic moved in bursts, but attacks, mines, retaliation and sanctions pressure kept the corridor high risk.

Severe

Tuesday traffic fell back

Only four commodity vessels were tracked through Hormuz on Tuesday, below the 10-day average near 13.

High

Monday flow was disputed

U.S. officials cited 17 million barrels of oil moving Monday, while vessel counts remain difficult because some ships disable transponders.

Severe

Two VLCCs were hit

Sidr and Senegal Prosperity were struck by unknown projectiles near Khasab after loading Saudi crude for outbound transit.

Severe

Crew fatalities confirmed

Bahri confirmed two Filipino seafarers died after the security incident involving Sidr in the strait.

High

U.S. strikes target maritime assets

American strikes hit Iranian radar, air defense, maritime, mine-laying and communications targets.

Watch

LNG shifts outside the strait

Rare LNG ship-to-ship transfers from Qatar and the UAE show exporters are using offshore workarounds to keep cargo moving.

Operator signal: the market is now dealing with a corridor that can produce one strong flow day, then fall back to a thin transit count while missile, mine, drone, insurance, crew-safety and sanctions risks remain live.

48-Hour Hormuz Situation Board

Traffic, Tanker Attacks, U.S. Strikes and Energy Workarounds

The latest picture is not a full closure, but it is far from normal commercial passage.

Tuesday commodity-vessel transits 4

One VLCC, one Panamax tanker, one Kamsarmax and one intermediate tanker were tracked through the strait.

Monday oil flow claim 17M barrels

U.S. Energy Secretary Chris Wright said Monday marked the highest crude flow through Hormuz since the war reduced traffic.

Saudi-loaded VLCCs hit 2

Sidr and Senegal Prosperity were struck by unknown projectiles during outbound transit near Oman.

Iran crude export disruption 7 weeks

Iran has gone about seven weeks without meaningful crude exports through Hormuz, according to tanker-tracking estimates.

Rare LNG transfers 3 cargoes

Qatar and UAE LNG cargoes were transferred ship-to-ship outside Hormuz for delivery to India and Japan.

Development Latest Detail Commercial Signal Stakeholder Exposure Pressure Meter
Tuesday Transit CountKpler preliminary vessel data Four commodity vessels transited Hormuz, down from 10 on Monday and below the 10-day average near 13. Traffic is still too thin and too volatile to call the route normalized. Owners, charterers and insurers face uncertain timing, higher screening and narrower safe-transit windows. Severe
Monday Flow Spike17 million barrel statement U.S. officials said Monday crude flow reached the highest level since war-related reductions began. A single high-volume day may show escorted or concentrated passage rather than sustained recovery. Cargo buyers need to separate headline barrels from repeatable daily capacity. High
Sidr AttackSaudi-flagged VLCC Sidr was struck near Khasab after loading Saudi crude, and Bahri confirmed two Filipino seafarer deaths. The attack moved Hormuz risk from routing disruption into direct crew-casualty and liability exposure. War-risk wording, crew rotation, hazard pay, deviation clauses and voyage authorization all become more sensitive. Severe
Senegal Prosperity AttackLiberian-flagged VLCC The vessel was reportedly hit by three unknown projectiles about 17 nautical miles east of Khasab. Near-simultaneous VLCC strikes suggest coordinated pressure on outbound Gulf crude movements. VLCC fixtures out of the Gulf now carry higher casualty, delay, salvage and insurance uncertainty. Severe
IRGC Mine ClaimTwo tankers reported on fire Iran’s Revolutionary Guard claimed two oil tankers hit mines and warned companies against unauthorized routes. Even unverified mine claims can change routing behavior, convoy planning and underwriter appetite. Marine security teams need live route validation, not just published lane assumptions. Severe
U.S. Strike PackageMaritime and mine-laying targets U.S. forces struck Iranian air defense, radar, maritime assets, mine-laying capabilities and communications sites. Washington is targeting the systems that support Iranian attacks on shipping. The near-term effect may be reduced attack capacity, but retaliation risk remains active. High
Iran RetaliationRegional targets Iran launched missiles and drones at U.S.-linked targets in the Gulf and broader region after the U.S. strikes. Hormuz risk is now tied to regional base defense, air defense and escalation cycles. Gulf ports, offshore terminals, naval escorts and energy buyers face linked maritime and air-threat exposure. High
Iran Crude Export StallBlockade pressure No Iranian crude cargoes have successfully moved through Hormuz to China since the July 14 blockade restart, according to tracking firms. The blockade is cutting into Iran’s export revenue more directly than sanctions alone. China-linked buyers, shadow-fleet owners, traders, banks and insurers face shrinking supply and higher enforcement risk. Severe
LNG STS WorkaroundsQatar and UAE cargoes Three LNG cargoes were transferred outside Hormuz in recent weeks, including cargoes linked to Qatar and the UAE. LNG is moving, but unusual STS handling shows normal direct-lift patterns are under pressure. LNG buyers need more attention on transfer risk, boil-off, compatibility, custody transfer and schedule integrity. High
Bab el-Mandeb ComparisonSecond chokepoint signal Tuesday Bab el-Mandeb commodity-vessel traffic was also below its 10-day average, though stronger than Hormuz. Middle East routing risk is broader than one strait, especially for tankers and LNG cargoes. Cape routing, Red Sea exposure, insurance quotes and fuel budgets need to be checked together. Medium High
Official Maritime AdvisoryHigh-risk operating area MARAD continues to warn of high risk to commercial vessels in the Persian Gulf, Strait of Hormuz and Gulf of Oman. Threats include missile attacks, armed UAVs, armed USVs, small boats and forced movement toward Iranian waters. Bridge teams, CSOs, P&I clubs, insurers and charterers need current voyage authorization and reporting discipline. Severe
