The Strait of Hormuz suffered another violent night on Tuesday as the British maritime security agency UKMTO confirmed that a tanker and a container ship were struck by projectiles of unknown origin in the world's most important oil chokepoint. The Hormuz ship attacks — now running at their worst pace since the US-Iran war began in February — have pushed oil flows through the strait to crisis levels, with maritime analysts at Kpler reporting that barely 2.9 million barrels a day were getting through on the worst strike day, down from a pre-war norm of 17 to 20 million.

How the Hormuz ship attacks reached their worst pace
The numbers, tallied from UKMTO data and European maritime security sources, make grim reading. A single-day record of six vessels was hit during the October 11–12 window, the heaviest fire on tanker and cargo traffic since the war began on February 28. More than 18 commercial vessels were targeted in the first 12 days of October alone, and at least 14 attacks, attempted attacks and interceptions were logged between October 5 and 12. One review put the two-week total at 24 ships struck — a pace the Washington-based Institute for the Study of War warns could get worse as Iran hones its targeting.
Tuesday's two hits are the freshest confirmation that the campaign isn't slowing. UKMTO's advisories are usually spare — a report of an incident, a location, a note that an investigation is underway — and this one was no different: projectiles of "unknown origin," no word yet on damage or casualties. What's changed is the context. Ships are now turning off their transponders to slip through the strait undetected, which is exactly what Iran's Revolutionary Guards say will get them targeted.

Tuesday's strikes: what UKMTO confirmed
According to the British agency's Tuesday advisory, reported late in the evening Gulf time, a tanker and a container ship were hit by projectiles whose origin could not be determined. The agency said an investigation was underway and did not specify whether the strikes caused damage or injuries. The incidents fit a pattern that has become depressingly familiar: vessels struck while trying to exit the strait, their crews filing late reports only after reaching safer waters.
The attacks land in the middle of a declared blockade campaign. The Islamic Revolutionary Guard Corps has openly described its operations as targeting "illegal oil smuggling and an attempt to break the Hormuz blockade," and says some of the damaged vessels struck naval mines while sailing routes Tehran considers unsafe. Iran's position, in short, is that the strait is closed to ships it hasn't cleared — a stance its navy underscored with a blunt warning: "All vessels within the Strait of Hormuz that switch off their navigation and identification systems will be identified as hostile and dealt with firmly and decisively."
India pulled into the crossfire
The human cost is falling disproportionately on Indian seafarers, who make up more than 12 percent of the world's maritime workforce. The October 11 attacks hit two ships carrying Indian crew: the Nicaragua-flagged MT Petro Dolphin, struck by a drone, with two Indian sailors still missing and ten others rescued; and the Marshall Islands-flagged MT Valthera, hit by a projectile and set on fire, though all 11 Indian sailors aboard were reported safe.
India's foreign ministry condemned the strikes and said the safety of Indian seafarers "remains a priority." National Security Adviser Ajit Doval spoke to his Iranian counterpart Mohsin Rezaei on Monday evening, according to Tehran, though neither side said whether the ship attacks were discussed. At least 11 Indian seafarers have been killed in the strait and the wider Gulf region since the war began, India's shipping ministry confirmed last week, and roughly 139 Indians are currently believed to be stuck in the waterway. External Affairs Minister S. Jaishankar has repeatedly pressed Iran's foreign minister to stop attacks on ships carrying civilians.

Oil markets feel the squeeze
The economic fallout is no longer theoretical. Kpler's data shows oil flow through the strait had recovered to 15.5 million barrels a day last month — close to normal, thanks in part to US naval escorts — before the October campaign knocked it down. On the worst strike day, only 2.9 million barrels got through, and the seven-day average now sits 43 percent below pre-war levels. Brent crude is hovering above $105 a barrel, and American drivers are paying more than $4.31 a gallon for gasoline, with diesel at $6.27, according to AAA.
The Hormuz campaign is the second energy front in a regional war that keeps widening. Next door, Saudi Arabia and Yemen's Houthis have spent the week trading strikes on oil infrastructure — the coalition bombing Houthi fuel sites around Sanaa and Hodeidah on Tuesday evening while the rebels threaten Saudi Aramco facilities directly. Two energy wars running in parallel is exactly what oil traders feared.
Why it matters
Hormuz is the artery of the global oil market, and Iran knows it. The current campaign looks less like random harassment and more like a deliberate effort to reassert control over the strait after months in which US-escorted traffic had brought flows nearly back to normal. If the pace holds — and the ISW warns Iran's anti-ship missile capabilities may still be improving — the world's spare oil capacity gets very thin, very fast. For the US and UK, already stretched between the Saudi-Houthi front and the blockade of Iranian ports, the question is how much protection they can actually provide to commercial shipping. For crews, mostly South Asian and Filipino, the calculus is simpler: another transit through a shooting gallery.
What happens next
Three things to watch. First, whether Washington responds to the October surge — the US has so far answered Iran's blockade with its own naval blockade of Iranian ports, plus escorts through the strait, but the attacks are outpacing the escorts. Second, whether Tehran's ceasefire-era memorandum with Washington, signed in June, still means anything; clashes already resumed in July after negotiations stalled. Third, the insurance market: with 24 ships hit in two weeks, war-risk premiums for Hormuz transits are about to become the story's next headline. The strait isn't closed — but it's getting closer to unusable with every passing week.

Frequently Asked Questions
What happened in the Strait of Hormuz on Tuesday?
Late Tuesday, the British maritime agency UKMTO said a tanker and a container ship were hit by projectiles of 'unknown origin' in the Strait of Hormuz. The agency said an investigation was underway and gave no word on damage or casualties. The strikes continue an October campaign running at the worst pace of the US-Iran war.
How many ships have been attacked in October?
UKMTO data and European maritime security sources put the toll at more than 18 commercial vessels in the first 12 days of October, with a single-day record of six ships struck during the October 11–12 window. One review counted 24 ships hit in two weeks, and at least 14 attacks or interceptions were logged between October 5 and 12.
Who is behind the attacks on ships in Hormuz?
UKMTO attributes the Tuesday strikes to projectiles of "unknown origin" and has not named a culprit. Iran's Revolutionary Guards, however, openly describe a blockade-enforcement campaign, saying they target ships accused of "illegal oil smuggling" and warning that vessels sailing dark will be treated as hostile. Tehran frames the operations as a response to a US naval blockade.
Why is India so heavily affected by the Hormuz attacks?
Indians make up more than 12 percent of the global seafaring workforce, putting many on ships transiting the strait. At least 11 Indian seafarers have died in the region since the war began, two went missing after the October 11 drone strike on the MT Petro Dolphin, and roughly 139 are stuck in the waterway.
How bad is the impact on oil prices and fuel?
Oil flows through the strait fell to 2.9 million barrels a day on the worst strike day, against a pre-war norm of 17–20 million, and the seven-day average is 43 percent below pre-war levels, per Kpler. Brent crude is above $105 a barrel, while US drivers pay over $4.31 a gallon for gasoline and $6.27 for diesel, according to AAA.
Is the Strait of Hormuz closed to shipping?
No. Traffic continues, much of it under US naval escort, and flows briefly recovered near pre-war levels last month. But with a record attack pace, ships sailing dark to avoid detection, and war-risk premiums set to soar, the strait is steadily harder and more expensive to use. Analysts warn it is edging toward effectively unusable if the campaign continues.
