Iran’s Hormuz Attacks Target the Route That Restored Crude

Iran has attacked nearly 20 commercial ships around the Strait of Hormuz in September and early October, according to the Joint Maritime Information Center. Crude through the strait still averaged 10.3 million barrels a day in the week ended October 4, about 23% below the 13.5 million barrels a day Kpler uses as a prewar baseline. Product cargoes, the diesel and gasoline that fill tanks, were only 1.3 million barrels a day, 11% of overall flows.

The barrels that returned are moving on a U.S.-escorted lane along Oman’s coast, then onto other ships waiting outside the strait. That workaround is what Iran is now shooting at, which is why Brent is still hovering near $100 a barrel and why Washington is letting American truckers burn cheaper red diesel.

Iran Is Shooting at the Oman-Coast Workaround

The Joint Maritime Information Center, a group of U.S.-allied militaries that brief merchant ships, has kept the strait at a SEVERE threat level, meaning a deliberate attack is treated as highly likely. Michelle Wiese Bockmann, senior maritime intelligence analyst at Windward, said Iran attacked roughly two ships for every 100 vessels that crossed in the third quarter.

The recent cluster is aimed at the southern lane, not at some abstract “Hormuz risk.” JMIC said attacks along the Omani side were continuing. A drone dropped into one tanker’s engine room through the funnel, starting a small fire and cutting power. Another ship was hit on its port quarter, lost power, drifted, then limped toward Fujairah with tugs. A third lost propulsion after a projectile strike. No crew were reported hurt in those four cases, logged as UKMTO incidents 147-26 through 150-26 on October 2 and 3.

THE OCTOBER ATTACK LOG

1. September 28 to 29, 2026: Four tanker strikes in the strait (UKMTO 143-26 through 146-26), inbound and outbound, with at least one small fire put out and one ship sent back to its last port for a damage check.
2. October 2 to 3, 2026: Four more confirmed tanker attacks on the Omani side, including the funnel-drone hit and two ships that lost power.
3. October 4, 2026: An inbound LPG tanker struck at 1716 UTC, then a crude tanker struck at 1907 UTC; UKMTO also logged a crude tanker hit above the waterline on October 3.
4. October 4 to 5, 2026: The master of a tanker about 11 nautical miles north of Khasab, Oman, is hailed by Iran’s Islamic Revolutionary Guard Corps, told to turn back or be targeted, and complies.
5. October 6, 2026: A Panama-flagged tanker, identified as the MT On Peace, is struck by a projectile off Oman, injuring 12 of 19 crew.

JMIC’s October 1 advisory note already counted four confirmed attacks or disruptions in a 96-hour window and 123 incidents in the wider region since March 1. Later notices arrived late, sometimes a day after the hit, so the live picture inside the strait is worse than any single bulletin.

The Khasab hail matters because it is not a missile. It is Iran telling a commercial master that the southern corridor is a permissioned lane. The ship turned around. Freedom of navigation, in that hour, was a VHF order.

Only 11% of Hormuz Cargo Is Fuel

Headline charts of a “Gulf rebound” mix three different things: crude that still crosses Hormuz, crude that never enters the strait, and the refined fuels that have not come back. Kpler’s regional seven-day average for Middle East crude reached 18.3 million barrels a day on September 30, against about 18 million barrels a day in the 12 months before the war, and Gulf flows excluding Iran recovered to more than 81% of prewar levels in September. Those regional totals include pipelines and ports that skip Hormuz. Kpler estimates about 40% of oil exports now bypass the strait, and much of the crude that does cross is transferred between tankers offshore.

The strait itself is a narrower story. Kpler’s 10.3 million barrels a day of Hormuz crude for the week ended October 4 is still about 23% below that 13.5 million barrel prewar baseline. Product cargoes at 1.3 million barrels a day are only 11% of overall flows through the waterway. Before the war they were typically more than 20%.

CRUDE VERSUS FUEL THROUGH HORMUZ

The U.S. Energy Information Administration put total oil through Hormuz at 21.6 million barrels a day in late 2025, then 4.9 million in the second quarter of 2026, after the war that began on February 28 shut the corridor down. Before that war the strait handled about 20% of global crude and liquefied natural gas supplies. JMIC’s 2025 baseline is about 138 ships a day. The quarterly collapse is why a 10.3 million barrel crude week can look like a rebound and still leave pumps short.

Tamas Varga, an analyst at PVM Oil Associates, tied the September lift to Saudi Arabia’s East-West pipeline and to ship-to-ship transfers around the strait. That pipeline has already been hit. Industry sources told JMIC it restarted at a reduced rate on September 22 and was feeding Red Sea refineries, with regular Yanbu crude loadings still unconfirmed at the start of October. A regional export number that counts those barrels is not a count of safe Hormuz transits.

How the Shuttle System Moves Crude Anyway

Crude is getting out because the trade was rebuilt around the danger, not because the strait became safe. In many cases a tanker brings oil through Hormuz, then transfers it in the Gulf of Oman onto a ship that will make the long haul to Asia. The shuttle cuts the time any one hull spends inside Iranian range, and it burns extra ships and extra insurance to do it.

U.S. forces have carved a southern route along Oman’s coast. JMIC recorded 113 U.S.-guided Strait of Hormuz transits from September 27 to 30, while U.S. NCAGS traffic averaged about 30 ship transits a day in that same 96-hour window, against the 138-a-day peacetime baseline. Independent trackers still saw single-digit crossings in both directions when they counted ships that were not in that guided flow.

THE THREE-PART WORKAROUND

• Oman-coast lane: Tankers run a southern corridor under U.S. protection rather than the northern Iranian-controlled route they are often hailed toward.
• Ship-to-ship transfers: Smaller shuttles, some sailing with transponders off, hand crude to larger hulls waiting outside the strait.
• Bypass pipes and ports: About 40% of current oil exports skip Hormuz entirely, until those lines get hit too.

Bob McNally, president of Rapidan Energy and a former White House energy adviser, said nobody in Washington thinks the military commitment, the transfers, and the freight bills are sustainable financially, calling it an inefficient way to move commodities out of Hormuz. Bockmann said the cost of shipping crude from the Persian Gulf to China has climbed to $1 million a day for each tanker. Chris Beauchamp, chief market analyst at IG Group, said the shuttle is doing wonders at getting oil out and that it requires plenty of ships, which do not get built overnight.

Iran still says the amount passing is negligible and that it controls the strait. President Donald Trump has said U.S. forces are protecting the ships that do go through. Both can describe the same map: a thin, escorted lane that can be harassed by a radio call off Khasab.

Why U.S. Truckers Are Burning Red Diesel

Crude returning to Asia does not refill a diesel tank in Ohio. Several large Middle East refineries were damaged in the war, so the missing cargo is the finished fuel. On October 5, U.S. retail diesel averaged $6.32 a gallon and regular gasoline $4.37, according to EIA figures drawn from AAA. Distillate crack spreads almost tripled their year-ago levels in the third quarter, the agency said, as global supply of transport fuels stayed tight.

That is the shortage the White House moved on. An October 5 executive order directed Treasury to temporarily allow dyed diesel on highways and to defer the federal excise tax on that fuel for the rest of the year, without interest or penalties. Off-road diesel is dyed red so it can be spotted; it is normally reserved for farms, construction, and heating. The White House said truckers could save more than $100 per refill. Agriculture was told to protect farm access in high-demand areas, and states were asked to match the federal deferral.

U.S. FUEL PRESSURE, EARLY OCTOBER

• Retail diesel: $6.32 a gallon U.S. average on October 5, EIA via AAA.
• Regular gasoline: $4.37 a gallon the same day.
• Trucker saving: More than $100 per fill-up if dyed diesel can be burned on the highway tax-free.
• G7 stockpile: Members said they would release up to 100 million barrels of strategic reserves, including diesel.

Varga put Brent at just under $100 a barrel against around $72 before the war, with shipping and insurance keeping the extra in the price. A crude rebound that does not restore product cargoes leaves the United States as one of the few large fuel exporters in a tight market, which is why the political fix is a tax waiver on red diesel rather than a claim that Hormuz is open.

The Seafarers on the Shuttle Run

The export recovery is being paid for on deck. Since July, at least nine sailors have died since July, 18 have been injured, and three are missing, according to the International Maritime Organization. On October 6, India’s Ministry of External Affairs said 12 seafarers were hurt when a Panama-flagged tanker was struck by a projectile in the strait. The ship was identified as the MT On Peace. Twelve of 19 crew were injured, 11 of them Indian nationals, and Omani authorities evacuated the wounded to Khasab.

Indian crews have been heavily exposed throughout the war because they staff so much of the world’s tanker fleet, including foreign-flagged hulls on the shuttle run. Bockmann put the point without dressing it up: volumes are getting through at a time of extremely high maritime risk. The funnel-drone strike and the On Peace projectile are the same operational choice. Masters are still being sent through a SEVERE-rated lane because crude freight can pay the extra, and product tankers have a harder time covering that bill.

JMIC has warned that IRGC activity is not limited to hits. UAV overflights, targeted surveillance, and VHF hailing are part of the pressure, and AIS-on ships can expect to be directed toward the northern route. Delayed reporting means a company can learn its ship was struck hours after the event. That lag is now part of the cost of using the Oman corridor.

Brent Stays Near $100 for a Reason

Richard Meade, editor in chief of Lloyd’s List, said in a late-September briefing that oil flows have recovered because market participants accepted more complexity and higher costs, and that the threat to tankers remains the same. Brent, he noted, was still hovering near $100 a barrel even as more crude left Hormuz.

The oil market is not becoming more secure. It is becoming more efficient at operating under sustained insecurity.

McNally said that if the market believed the rebound was sustainable, prices would already be much lower, and that they stay high because it is still costly to deliver, insure, and land crude where benchmark prices are set. Amin Nasser, chief executive of Saudi Aramco, told the Energy Intelligence conference in London that rebuilding depleted inventories while meeting demand could take as long as two years, and that the system is already straining. Varga said only a lasting peace and a full, unconditional reopening of the strait would restore the prewar status quo.

Charts that print 18.3 million barrels a day of regional crude do not cancel a SEVERE warning, a $1 million daily Gulf-to-China freight bill, or a master who turned around 11 nautical miles north of Khasab. They also do not put diesel back on the water. Until product cargoes recover with the crude, the Hormuz rebound will keep showing up at the pump as a tax workaround and a price near $100, not as a reopened strait.
