NextFin News - Attacks on ships in the Strait of Hormuz have reached the worst level since the 2026 war began, with at least 12 tankers struck in a single week in early October, as daily transits through the world's most important oil chokepoint collapsed to single digits and crude prices pushed above $100 a barrel. The United Nations maritime agency confirmed 88 incidents and 24 seafarer fatalities in the region as of 30 September, and the assault tempo has accelerated since. Traffic through the strait fell to just eight ships on one recent Sunday and 11 on Saturday, compared with more than 100 per day before the war, according to ship-tracking data from Kpler. The number of vessels loading crude for export to Asia dropped to about four a day, the lowest point since the conflict started. Brent crude rose above $100 a barrel after a fresh attack shut Saudi Arabia's East-West pipeline, the key bypass that had allowed Gulf producers to route oil around the strait to the Red Sea, before easing to $97.72 on 6 October.
The Chokepoint That Refuses to Reopen
The central tension is this: the Strait of Hormuz briefly appeared to be reopening, yet the threat to oil trade is now worse than at any point since the war started. Through the spring and early summer, U.S. naval protection and strikes that degraded Iranian radar and communications allowed shipments to rebound toward prewar levels. Gulf producers built an elaborate shuttle system in which tankers load inside the Persian Gulf, exit Hormuz, and transfer crude to vessels waiting outside the waterway. U.S. Central Command said thousands of ships and 1 billion barrels of oil had passed through in recent months.
That recovery has stalled. The resumption of strikes between the United States and Iran roughly a month after a June pause, combined with a fresh wave of attacks on tankers, has pushed traffic back toward the lows of March. "In terms of threat to the trade of crude, we're at the worst period that we've been in since this crisis began," said Matthew Wright, an analyst at Kpler.
The mechanism is straightforward and brutal: Hormuz is not the Red Sea. When Houthi attacks made the Bab al-Mandeb route hazardous, tankers could detour around the Cape of Good Hope, adding distance but preserving the voyage. There is no equivalent bypass for the Persian Gulf. Saudi Arabia's 1,200-kilometre East-West pipeline to the port of Yanbu was the only meaningful alternative, carrying more than 5 million barrels a day of exports before it was hit by drone strikes launched from Iraqi territory in September and halted again in early October. Once that valve closed, every barrel leaving the Gulf had only one exit.
The result is a growing queue of trapped tonnage. Automatic-identification data shows dozens of tankers that surged toward the strait after Iran's foreign ministry announced a reopening on 17 April reversing course and remaining stuck in the Gulf. Many vessels now "go dark," switching off their transponders to avoid detection while crossing the strait. Six of the 28 commodity vessels that passed through the Bab el-Mandeb on one recent Saturday had their transponders off, Kpler data showed.
"Not only is the ongoing situation in the Strait of Hormuz constraining oil flows, but now a big factor that was helping to balance the market is now also under threat. It's a problem stacked on top of a problem," Wright said.
The Freight and Insurance Bill
The market's response has been a repricing of risk on a scale not seen in modern tanker markets. War-risk insurance premiums have surged to between 3 per cent and 10 per cent of a vessel's hull value, up from about 0.25 per cent before the war. A $100 million tanker now faces a premium of $3 million to $10 million per transit, compared with roughly $250,000 before hostilities began. Insurers that once wrote annual cover now price voyages one by one, and political-violence coverage trades at several multiples of pre-conflict levels.
Freight rates have followed. The benchmark VLCC route from the Middle East to China, known as TD3C, reached $451,000 a day on 12 September, an all-time high. The fleet-wide ClarkSea Index stood at $56,567 a day in mid-September, up 91 per cent year on year. Secondhand tanker values have repriced accordingly: a 15-year-old VLCC rose 62 per cent between July and September, from $83.5 million to $135 million, while a newbuild costs about $130 million. Buyers are paying a premium for tonnage that can trade now.
But the forward market tells a different story, and that gap is the clearest signal of what traders actually believe. In early June, forward freight agreements for the fourth quarter priced Gulf-China earnings at $181,163 a day, less than half the spot rate at the time. That discount is the market's bet that the disruption is temporary: once trapped ships return to service and the strait reopens, the tonnage glut will push rates back toward normal.
The insurance market has priced the same view more cautiously. A March industry report found war-risk premiums at 2 per cent to 3 per cent of vessel value for a standard transit, with worst-case voyages reaching $3 million. By July, rates had climbed to the 3 per cent to 10 per cent range. The spread between the forward freight curve and the insurance curve is the clearest read available: freight traders are underwriting a reopening; insurers are underwriting a longer war.
Cyclical Shock or Structural Rerouting?
The critical question for investors is whether this is a cyclical disruption that will mean-revert or a structural shift in how oil moves around the world. The answer is both, and separating them matters because it determines which repricings stick.
The traffic collapse is cyclical. It is driven by a specific, reversible cause: active hostilities and the absence of a secure escort regime. History offers a clear mean-reversion pattern. After the temporary peace deal with the United States in early June, transits rose again within weeks. If a negotiated settlement restores safe passage, the 100-plus ships a day that used the strait before the war will return, and the queue of trapped tankers will drain. Hapag-Lloyd, the global container carrier, estimated that most ships could leave the region "fairly quickly" if the strait reopened, though restoring normal cargo flows would take three to four months because services have been suspended and vessels redeployed elsewhere.
But three structural changes are already locked in and will not reverse on their own. First, the risk premium has become a permanent line item. Even if premiums fall from 10 per cent of hull value, they will not return to 0.25 per cent; underwriters now model the strait as a recurring high-risk zone. Second, the routing architecture has changed. Shippers that once relied on Hormuz plus the East-West pipeline have been forced to test longer alternatives, and the knowledge that the pipeline is itself vulnerable removes the only credible bypass. Third, the fleet itself has been repriced: older tonnage that would have been scrapped is now earning record rates, and newbuilding orders take years to deliver, meaning supply cannot respond quickly to the next spike.
This is where the second-order effect bites. The conventional read is that higher freight and insurance costs raise the price of oil. The deeper channel runs the other way: the cost of moving oil is now a constraint on supply itself. When a $21 million insurance bill sits on top of a $12 million voyage, marginal cargoes do not ship. That is why crude exports to Asia have fallen to four ships a day even as Gulf producers say they want to sell. The bottleneck is no longer production; it is passage.
"We now have the high-risk area going up to Saudi Arabian waters and extending into parts of the Red Sea," said Tim Wilkins, managing director of Intertanko, the trade body representing tanker owners. "So that's having another impact on the market, on freedom of navigation as well."
Peter Sand, chief analyst at Xeneta, put it more bluntly: the fighting has taken shipping "back to square one," with the industry in "a terrible state, regardless of which shipping type you're looking at."
The Counter-Thesis: The Reopening Was Real
The strongest case against a structural read is that the reopening already happened and the recent attacks are noise on top of a functioning corridor. U.S. Central Command reports that thousands of ships and 1 billion barrels of oil have transited Hormuz in recent months. The shuttle-transfer system and U.S. naval escorts demonstrably moved volumes. From this view, the spike in freight rates is a classic cyclical overshoot, and the forward curve at $181,000 a day is the rational anchor.
The counter-argument fails on one point: capacity to move oil under escort is not the same as reliable, insurable capacity at scale. Twelve attacks in a week is enough to keep a large share of the fleet on the sidelines, because a single strike can total a $250 million vessel and its cargo. The shuttle system works for producers with government-backed fleets willing to absorb the risk; it does not work for the independent owners who carry a large share of global crude. That is why traffic remains at a fraction of prewar levels even with escorts in place.
The falsifying signal is observable: if daily transits through Hormuz sustain more than 50 ships for two consecutive weeks and war-risk premiums fall below 1 per cent of hull value, the structural-risk thesis is wrong and the forward curve wins. Neither condition currently holds. Transits are in single digits, and premiums sit at 3 per cent to 10 per cent.
What Comes Next
The near-term path depends on diplomacy more than economics. Iran has denied U.S. claims that it is in talks with Washington over reopening the strait, while saying it is speaking to Oman about securing the shipping lane. Iran's foreign ministry spokesman Esmaeil Baqaei said any agreement would not lift current restrictions while U.S. "aggression" continued. A deal that brings the United States into the framework could restore traffic within weeks; one that leaves the security architecture unresolved will keep the strait effectively closed regardless of declarations.
The U.S. Energy Information Administration forecasts Brent crude averaging $105 a barrel in the fourth quarter of 2026, $14 higher than its previous estimate, assuming Middle East flows remain constrained and shut-in production averages 4.5 million barrels a day. It expects prices to fall to $87 by the second quarter of 2027 and $74 by the end of 2027 as production returns and inventories rebuild. Independent models point to a similar path, with Brent expected to average $106.60 by the end of the current quarter.
Three scenarios frame the outlook. The base case is continued volatility: the strait stays partly open under escort, transits hover well below prewar levels, and Brent trades in the $95 to $110 range while freight rates remain elevated but below their peaks. The upside case is escalation: a strike that closes the strait fully or takes out additional pipeline capacity would push Brent toward the March peak near $140 and send TD3C rates back above $400,000 a day. The downside case is a negotiated reopening: a U.S.-backed security framework that restores transits toward 50 a day would collapse freight rates toward the forward curve and pull Brent back toward $80.
Across time horizons, the signals point in different directions. Short term, sentiment will track each strike and each diplomatic statement, producing sharp two-way moves. Medium term, fundamentals favor elevated rates and prices as long as transits stay constrained and inventories remain thin. Long term, the structural lesson is that a single 39-kilometre-wide passage at its narrowest carries roughly a fifth of the world's oil and gas, and no credible alternative exists.
The market is currently pricing a reopening that the insurance market refuses to underwrite. Until those two prices converge, the strait stays closed in the only way that matters for global trade: not by declaration, but by premium.
