LONDON, Oct 24 — October 2026 has become the worst month on record for attacks on commercial shipping in the Strait of Hormuz and nearby waterways, according to data compiled by the Washington Institute for Near East Policy, as the shadow war around the world's most important oil chokepoint intensifies and Brent crude pushes above $116 a barrel.
The think tank, which has tracked maritime security incidents worldwide since 2017, has recorded 28 confirmed and reported attacks in the strait and surrounding waters this month alone, and 113 since the U.S.–Israeli war with Iran began on February 28. The tally broadly aligns with International Maritime Organization figures, and it is already reshaping global shipping economics: daily freight rates for the Gulf now exceed $1 million, and more than 30 supertankers — about 3.5% of the global fleet — have been damaged since the conflict began.

What Happened
"October has seen the highest number of ship attacks on record," Noam Raydan, a senior fellow at the Washington Institute who maintains its interactive shipping incident map, told Reuters on October 23. Most of the September and October attacks took place inside the Strait of Hormuz itself, through which roughly a fifth of the world's oil consumption flows.
The International Maritime Organization has recorded 120 incidents in the Strait of Hormuz and the wider Middle East since the conflict with Iran began, and its list includes more than 30 Very Large Crude Carriers (VLCCs) damaged in the attacks — 11 of them in October alone, according to a Reuters review of the IMO list and MarineTraffic vessel data. Each VLCC can carry about 2 million barrels of crude, and the listed vessels account for roughly 3.5% of the total global VLCC fleet of more than 900.
The pace is still accelerating. Greece-based consultancy Marisks said October 2026 "has emerged as the most intense period of maritime attacks in and around the Strait of Hormuz since the escalation of hostilities in March," noting that a dozen ships were attacked between October 5 and 11 — the highest weekly number since the conflict began.
Background
The surge in attacks reflects a grim economic logic. Reuters reported that more tankers have come under attack partly because shipowners have become "increasingly willing" to load cargoes inside the Gulf, lured by daily freight rates exceeding $1 million and steeper discounts offered by regional producers against dated Brent. The risk premium, in other words, is being priced in — and paid.
The shipping crisis is inseparable from the broader Middle East war that began with the U.S.–Israeli campaign against Iran on February 28. The International Monetary Fund's October 2026 outlook traced much of this year's economic disruption to that conflict: shipping through the Strait of Hormuz has been disrupted since March, hitting the Gulf's oil economies hard. Saudi Arabia's economy is expected to contract 3.3% this year, while inflation across the Middle East is forecast to soar to 16.3%.
The effects are already visible on trading floors. On Friday, October 23, Wall Street closed lower — the S&P 500 down 0.5%, the Dow Jones down 1.2% and the Nasdaq off 0.2% — while Brent crude climbed above $116 per barrel and the U.S. 10-year Treasury yield sat at 4.99%, according to market data reported by the Associated Press. For the week, the S&P 500 and Nasdaq declined 0.5% and 0.7% respectively, while only the Dow gained, up about 0.4%.

Why It Matters
The Strait of Hormuz is the kind of chokepoint whose disruption transmits instantly to everything else: petrol stations, supermarket shelves, government budgets. Germany's foreign minister, Johann Wadephul, made the point explicitly this week ahead of the seven-country security talks in Istanbul, warning that attacks on shipping routes hit ordinary consumers "whether at the petrol station or in the supermarket" and that disruptions to fertilizer deliveries could trigger famine in parts of the world. "We will not accept Iran and the Houthi militias holding global trade hostage," he said.
The economic transmission runs through two channels at once: energy prices and freight costs. Oil above $116 feeds directly into inflation at a moment when the IMF already expects global inflation to rise from 4.1% in 2025 to 4.7% in 2026, with things "more likely to get worse than better" — the Fund's warning covers wider conflict, new trade disputes, government debt problems and the chance that the AI bubble bursts. Freight rates above $1 million a day add a second layer of cost that lands, eventually, on consumers.
There is also a structural warning embedded in the attack data. When 3.5% of the global supertanker fleet is damaged and owners keep sailing anyway because the rates justify the risk, the market is telling you that the world's energy logistics have almost no slack. A single further escalation — a closed strait, a sunken VLCC blocking a lane — would turn a record-bad month into a systemic shock.

What Happens Next
All eyes are on the shipping data for the rest of October: if the current pace holds, the month will close as the worst on record by a wide margin, and insurers will reprice war-risk premiums for Gulf voyages accordingly — costs that flow straight into freight rates and, eventually, fuel prices.
The diplomatic calendar offers two potential circuit-breakers. The Istanbul meeting of seven countries' foreign ministers — Turkey, Egypt, Pakistan, Saudi Arabia, Britain, France and Germany — put shipping security at the center of its agenda this week. And a U.S.–China framework agreement reached on October 18 in Kuala Lumpur, which averted threatened 100% U.S. tariffs and delayed Chinese rare-earth export controls, is set for signing at the Trump–Xi summit in South Korea on October 30, according to media summaries — a de-escalation on the trade front that could calm at least one source of market anxiety.
But the fundamental driver — the war with Iran and its spillover into the waterways — shows no sign of abating. Until it does, the world's oil will keep moving through the most dangerous shipping lane on earth, one $1-million-a-day voyage at a time.

FAQ
What is the Strait of Hormuz and why does it matter?
The Strait of Hormuz is the narrow waterway between Iran and Oman through which roughly a fifth of the world's oil consumption flows. Any disruption there transmits immediately to global energy prices, freight costs and inflation.
How bad were the October 2026 ship attacks?
According to the Washington Institute for Near East Policy, 28 confirmed and reported attacks occurred in October — the worst month since it began tracking in 2017 — and 113 since February 28. The IMO recorded 120 incidents in the wider region, with more than 30 supertankers damaged, 11 in October alone.
Why do shipowners keep sailing through the danger zone?
Reuters reported that owners have become "increasingly willing" to load cargoes inside the Gulf because daily freight rates now exceed $1 million and regional producers offer steep discounts against dated Brent — the risk premium is being priced in and paid.
How is this affecting oil prices and markets?
Brent crude climbed above $116 a barrel as the attacks intensified. On October 23, the S&P 500 fell 0.5%, the Dow lost 1.2% and the Nasdaq slipped 0.2%, with the U.S. 10-year Treasury yield at 4.99%, according to AP-reported market data.
What could ease the crisis?
Analysts point to two diplomatic tracks: the seven-country foreign ministers' meeting in Istanbul, which put shipping security on its agenda, and the scheduled October 30 Trump–Xi summit in South Korea, where a U.S.–China framework deal is to be signed. Neither addresses the underlying Iran conflict driving the attacks.
