Persian Gulf shipping under attack as US-Iran war spreads to commercial tankers
Force in Play
Iran claimed three tankers hit mines on Oct 30, a day after UKMTO confirmed a projectile strike off Oman. Trump says the war will 'end soon' as Qatar mediates, and Iran says a US drone wounded fishermen near Qeshm.
UKMTO confirmed a tanker was hit by an unidentified projectile near Khasab, Oman, on Oct 29. Iran's Revolutionary Guard said three tankers struck mines in the Strait on Oct 30, including a supertanker, but the US military denied the claims ([gulfnews.com](https://gulfnews.com/world/mena/middle-east-war-iran-claims-tankers-hit-mines-in-strait-of-hormuz-ukmto-confirms-strike-off-oman-fired-us-general-reportedly-admitted-iran-leaks-1.500729137)).
Trump said on Oct 30 the war is 'going to end soon' as Qatar pushed a US-Iran deal, while Tehran's seven-day Hormuz reopening plan remained on the table ([cbsnews.com](https://www.cbsnews.com/live-updates/iran-war-us-trump-diplomacy-threat-resume-attacks/)). On Oct 31, Iranian authorities said a US drone bombed two fishing boats south of Qeshm Island and wounded several fishermen ([aljazeera.com](https://www.aljazeera.com/news/2026/10/31/iran-warns-of-unfettered-retaliation-if-attacked-as-mediators-try-for-peace)).
Why it matters
Each new strike raises tanker insurance and freight costs, and the war's outcome could decide who controls the world's most important oil chokepoint.

Scenarios
1
US Navy begins convoy escorts; strait partially reopens under military protection
Likely
Discussed by: USNI News, Bloomberg, and maritime analysts drawing parallels to Operation Earnest Will (1987). The Trump administration has already announced the legal framework via the DFC insurance order.
The US Navy organizes convoy escorts through the Strait of Hormuz, similar to Reagan-era reflagging operations during the 1980s tanker war. With government-backed insurance replacing commercial coverage and warships accompanying tankers, some shipping companies resume transits. Oil prices stabilize but remain elevated due to reduced throughput and the risk of Iranian mines or fast-boat attacks on convoys. This scenario depends on the US Navy having sufficient minesweeping capability to clear the strait and the political willingness to risk a direct naval confrontation with the IRGC.
2
Strait remains closed for weeks; oil prices spike above $100 as strategic reserves deploy
Possible
Discussed by: Energy analysts at Goldman Sachs and JP Morgan, CNBC, and the International Energy Agency. Analysts note that global strategic petroleum reserves, while substantial, cannot replace 20 million barrels per day of Gulf throughput indefinitely.
IRGC mining of the strait and continued drone-boat attacks prevent any reopening despite US military presence. Countries dependent on Gulf oil, particularly China, India, Japan, and South Korea, draw down strategic reserves while scrambling for alternative supply. Brent crude climbs past $100 per barrel. Global recession fears intensify as energy costs cascade through supply chains. This scenario is most likely if Iran successfully deploys sea mines across the shipping lanes, which US minesweeping operations would take weeks to clear.
3
Ceasefire or diplomatic deal halts attacks; shipping resumes within days
Uncertain
Discussed by: European foreign ministers, UN Security Council discussions, and Gulf Cooperation Council mediators. China, as the largest buyer of Gulf oil, has a direct interest in brokering a halt.
International pressure, particularly from oil-importing nations facing economic damage, produces a ceasefire or narrow agreement covering maritime traffic. Iran, having demonstrated its ability to close the strait, extracts concessions in exchange for reopening it. Shipping resumes gradually as insurers reinstate coverage. This scenario becomes more plausible if Iran's conventional military capacity is degraded enough that continued attacks become unsustainable, or if regime survival calculations shift under new leadership following Khamenei's death.
4
Attacks spread to Gulf state ports and energy infrastructure, widening the war
Possible
Discussed by: Flashpoint intelligence assessments, CSIS analysis, and Pentagon briefings. The Sonangol Namibe attack deep inside the Gulf already signals geographic expansion.
Iran escalates beyond targeting ships in transit, striking port facilities, oil terminals, and desalination plants in Kuwait, Saudi Arabia, and the UAE. The conflict widens from a maritime chokepoint dispute into a broader regional infrastructure war. Gulf states, initially bystanders, are drawn into direct confrontation. Energy markets enter crisis as not just transit but production capacity comes under threat. The northward creep of attacks, from the Strait of Hormuz to waters off Kuwait, suggests this escalation pathway is already underway.
5
Multinational coalition launches convoy escorts and minesweeping with US leadership
Likely
Discussed by: Joint statement from seven allies (UK, France, Germany, Italy, Netherlands, Japan, Canada) on March 19; maritime analysts comparing to Operation Earnest Will.
Building on US DFC insurance and Navy escorts, allies contribute naval assets for joint convoys and mine-clearing, partially restoring traffic. IRGC targets coalition ships, risking wider naval battle, but overwhelms asymmetric threats. Oil prices ease if throughput resumes 50%+ of normal.
6
Multinational coalition forms for Hormuz patrols; traffic resumes under allied protection
Likely
Discussed by: Joint statement from UK, France, Germany, Italy, Netherlands, Japan, Canada; USNI and maritime analysts.
Seven allies declare readiness to support reopening the strait, potentially expanding US Navy escorts into a coalition similar to Operation Prosperity Guardian but focused on Hormuz. With DFC insurance and multinational warships, tankers resume limited transits. Success hinges on minesweeping capacity and deterring IRGC attacks amid recent US sinking of 60+ vessels.
7
MOU signed; Strait of Hormuz formally reopens by late July 2026
Deadline passed (Jul 31, 2026)
Discussed by: CNN, Euronews, and CNBC covering the May 28 tentative agreement; Treasury Secretary Scott Bessent and unnamed negotiators on both sides
Trump and Iran's supreme leader both sign the memorandum of understanding, triggering a 30-day negotiation window on a full agreement. The Strait formally reopens, war-risk insurance markets reinstate coverage, and stranded tankers begin transiting freely. Oil prices fall toward $80/bbl. The 45+ running total of UKMTO incidents stops accumulating.
8
Mediated partial reopening: Iran reopens the strait under an Iran-Oman traffic deal, no tolls
Possible
Resolves by End of 2026
Discussed by: Regional officials and a senior US official briefing the AP; Qatari and Omani mediation channels
Mediators are shaping a proposal under which Iran reopens the strait in line with a separate Iran-Oman arrangement that manages shipping traffic and charges no tolls, in exchange for lifting the US blockade and later waiving sanctions. The US has not officially rejected the current proposal despite Trump's public comments, which officials read as a negotiating tactic. If it lands, tanker traffic normalizes and war-risk cover returns.
9
Shuttle system slows as Iran targets it
Possible
Resolves by Nov 15, 2026
Discussed by: Lloyd's List editor Richard Meade, Bloomberg, USNI News
Rezaei declared the US-assisted oil shuttle an explicit target, and Tehran says it strikes five or six shuttle vessels nightly. Bloomberg counted at least 10 VLCCs that stopped or turned back before Fujairah, the shuttle's staging hub. If the shuttle slows, Gulf exports fall from prewar levels and oil prices climb.
10
US retaliates after midterms; Hormuz attacks escalate further
Possible
Resolves by Nov 10, 2026
Discussed by: Al Jazeera, Iran International analysts and maritime security experts
Trump said on Oct 30 the war was 'going to end soon.' Iranian authorities said a US drone bombed fishing boats off Qeshm on Oct 31, before the Nov 3 midterms. If Washington retaliates further for the October tanker strikes after the vote, Iran could escalate to undersea cables and data centers as Mohsen Rezaei threatened.
Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1 of 3
1981-1988
Iran-Iraq Tanker War and Operation Earnest Will (1981-1988)
During the Iran-Iraq War, both sides attacked commercial shipping in the Persian Gulf to choke off each other's oil exports. Over seven years, 411 ships were attacked, 239 of them oil tankers, killing more than 400 civilian sailors. Iraq used fighter jets armed with Exocet missiles; Iran deployed small boats and naval mines.
Then
In 1987, the Reagan administration reflagged 11 Kuwaiti tankers as US vessels and deployed over 30 warships to escort convoys under Operation Earnest Will. On the first escort mission, the tanker MV Bridgeton struck an Iranian mine.
Now
The operation succeeded in keeping oil flowing despite Iranian attacks, but at the cost of the USS Samuel B. Roberts striking a mine and the US Navy accidentally shooting down Iran Air Flight 655, killing 290 civilians. The precedent of US Navy convoy escorts is now directly informing the Trump administration's response.
Why this matters now
Trump's March 3 announcement of Navy escorts and government-backed insurance directly mirrors Reagan's 1987 playbook. The 1980s tanker war also demonstrated that even a major naval presence cannot fully prevent mine attacks and small-boat harassment in the Gulf's confined waters.
2 of 3
May-June 2019
Gulf of Oman tanker attacks (2019)
Six commercial vessels were damaged in two separate incidents near the Strait of Hormuz in May and June 2019. The US attributed the attacks to Iran, pointing to video footage appearing to show IRGC personnel removing an unexploded limpet mine from the hull of the Japanese-owned tanker Kokuka Courageous. Iran denied responsibility.
Then
Oil prices spiked temporarily and war-risk insurance premiums rose, but shipping continued through the strait. The US formed the International Maritime Security Construct, a multinational naval patrol coalition.
Now
The attacks demonstrated Iran's ability to threaten Gulf shipping through deniable asymmetric tactics without triggering a major military response. They established a template for exactly the kind of escalation now playing out at a far larger scale.
Why this matters now
The 2019 attacks were probing operations: small-scale, deniable, and designed to demonstrate capability without crossing a threshold for military response. The current wave of attacks has abandoned deniability entirely, with the IRGC openly claiming control of the strait. The shift illustrates how a full-scale military confrontation has removed Iran's incentive for restraint.
3 of 3
November 2023 - 2025
Houthi Red Sea shipping attacks (2023-2025)
Yemen's Houthi forces, an Iranian-backed group, launched over 100 attacks on commercial shipping in the Red Sea and Gulf of Aden using missiles, drones, and explosive boats. The attacks forced major shipping lines to reroute vessels around the Cape of Good Hope, adding 10-14 days and significant costs to Asia-Europe trade routes.
Then
A US-led naval coalition, Operation Prosperity Guardian, failed to stop the attacks. Container shipping rates between Asia and Europe tripled at their peak. War-risk insurance premiums for Red Sea transit climbed to historic levels.
Now
The Houthi campaign proved that a militarily modest force could disrupt global shipping lanes for an extended period despite the presence of advanced naval forces. Insurance markets, not military escorts, became the binding constraint on commercial shipping.
Why this matters now
