NextFin News - The Strait of Hormuz has stopped being the energy market's worst-case scenario and become its working assumption. Mitsui O.S.K. Lines, the world's largest tanker operator, warned this week that disruption in the strait could extend beyond 2026 and into 2027 — a timeline that runs well past the recovery embedded in current gas prices. The warning arrived as Asian spot LNG climbed to its highest level in roughly two and a half years, European storage sat nearly 20 percent below its five-year average, and daily vessel transits through the 21-mile-wide chokepoint fell to single digits.
Here is the tension that defines the story: global LNG export volumes have held at record highs because the United States and other non-Gulf suppliers stepped into the breach, yet prices are behaving as if supply is critically tight. The market is no longer pricing how much gas exists. It is pricing how much it costs to believe that gas will actually arrive.
The Chokepoint That Stopped Breathing
The Strait of Hormuz normally carries about a fifth of the world's oil and liquefied natural gas. Before the conflict began on February 28, between 90 and 110 vessels passed through each day. On September 10, preliminary ship-tracking data showed just seven transits — four exiting, three entering — below the 10-day average of 14. At the peak of the disruption, flows collapsed by more than 90 percent.
The toll is heaviest on Asia. Japan, which before the closure imported more than 90 percent of its crude from the Middle East, mostly across the strait, saw its Gulf imports fall 64 percent between April 2025 and April 2026. LNG was hit hardest of all: Gulf LNG exports dropped 95 percent in April from a year earlier, according to International Trade Centre data — far steeper than urea (down 83 percent), methanol (80 percent) or ammonia (75 percent). Cumulative LNG supply losses from the disruption have now exceeded 50 billion cubic meters.
Prices have repriced the risk. The Northeast Asian spot LNG benchmark, JKM, for October delivery reached the mid-USD 28s per million British thermal units on September 11, the highest level in about two and a half years and up from the mid-USD 25s a week earlier. Europe's TTF front-month rose to USD 27.0 per MBtu on September 11 from USD 24.5 per MBtu the prior weekend. The United States is the outlier: Henry Hub slipped to USD 2.8 per MBtu from USD 3.0 per MBtu a week earlier, weighed down by robust domestic production and inventories sitting 4.8 percent above the five-year average. The JKM-Henry Hub spread, above USD 21 per MBtu, is not merely a price gap. It is the cost of a broken arbitrage.
Freight tells the same story in a different currency. Spot charter rates for tri-fuel diesel-electric LNG carriers jumped from around USD 5,000 a day in early February to roughly USD 235,000 by early March, and Atlantic Basin spot rates reached about USD 300,000 a day — the highest since the 2022 gas crisis, a roughly 600 percent move. Even with some traders pricing in a possible reopening, industry assessments expect LNG carrier spot rates to hold near USD 100,000 a day, because shipowners and insurers are waiting for evidence that the strait is genuinely safe rather than merely passable.
Why the Price Spike Is the Easy Part
The first-order mechanics are simple. When the strait closed, Qatar and the United Arab Emirates lost their shortest route to Asia. Every cargo that still moves must either wait, pay a war-risk premium, or travel farther. That alone would tighten the market. Three amplifying forces turned a supply shock into a rate shock.
Longer routes absorb tonnage. A US Gulf Coast cargo bound for Asia that would normally cross the Red Sea now faces a longer routing; a Qatari cargo that once cleared Hormuz in hours now sits idle or detours around the Cape of Good Hope. Distance does not destroy molecules, but it destroys effective shipping capacity — the same vessel completes fewer voyages per year, so the market needs more ships to move the same gas.
The price spread itself pulls vessels out of position. When JKM traded at a premium of nearly USD 5 per MBtu over TTF, cargoes were incentivized to divert from Europe to Asia. Those diversions lengthen routes further and strip Europe of nearby supply, forcing European buyers to bid against Asian purchasers for the same Atlantic Basin tonnage. The spread is both a signal and a self-fulfilling prophecy.
The carrier fleet is finite and inflexible. LNG carriers are not bulkers — they are specialized, expensive, and mostly committed under long-term charters. The spot market is a thin slice of the fleet, and when panic hits, competition for that thin slice sends daily rates parabolic. A 600 percent move in freight is what happens when a small spot market meets a large fear.
And yet the puzzle that separates a cyclical spike from a structural shift remains: global seaborne LNG export volumes did not fall. From January through April, total exports reached a fresh record of just over 149 million metric tons, up 6 percent year over year. The United States shipped roughly 7 million metric tons more LNG than a year earlier — more than enough to offset Qatar's 6.93-million-ton decline over the same period. Venture Global's Plaquemines terminal in Louisiana, which can sell cargoes on the spot market as it ramps, has been the largest single contributor. In pure volume terms, the market already adjusted.
The price action, then, is not about how much gas exists. It is about the price of believing it will arrive.
Reliability Is the Commodity That Broke
This is where the cyclical-versus-structural question decides the whole analysis. The cyclical reading says the strait will reopen, transits will normalize, freight will fall back toward pre-crisis levels, and JKM will mean-revert. That view is not wrong — it is incomplete. The deeper shift is that Hormuz has moved from "insurable tail risk" to "persistent operating condition," and that reclassification is permanent even if the physical blockade is not.
The evidence sits in the cost structure, not the price. War-risk insurance quotes on Gulf voyages have swollen to between 7.5 and 10 percent of hull value. Fuel costs on affected corridors have roughly doubled. Saudi Arabia has built bypass infrastructure — crude and condensate loadings at the Red Sea port of Yanbu rebounded to 3.7 million barrels a day in September from a six-month low of 3.2 million barrels a day in August — but those pipelines carry oil, not LNG. There is no equivalent reroute for Qatari gas. The geography is unforgiving: Qatar's Ras Laffan export complex sits on the Gulf side of the strait, and no pipeline bypass exists.
That asymmetry has already shifted bargaining power. Asian and European buyers have begun demanding lower prices and additional supply guarantees from Qatar and the UAE, eroding the reputation for reliability that once gave Gulf producers significant negotiating leverage. A buyer who once signed a 20-year contract assuming uninterrupted flow now prices a recurrence risk into every deal.
"Going forward (Gulf suppliers) will have to contend with a new risk profile stemming from what happened in the Strait of Hormuz and from the fact that nobody can rule out the possibility of a recurrence in the future," said an executive at Italy's Edison during the crisis.
That sentence captures the structural thesis in one line. The risk of recurrence does not evaporate when the strait reopens; it becomes a permanent line item in every contract negotiation, every insurance quote, every capital decision touching Gulf-linked LNG.
The International Energy Agency's third-quarter gas market report shows how far the baseline has moved. Its forecast assumes the strait fully reopens in the third quarter of 2026 and that regional facilities are fully restored by early in the fourth quarter, with Qatari and Emirati deliveries ramping progressively between July and October. The global reference case now embeds a seven-month disruption as the foundation for "normal." A baseline that treats a seven-month chokepoint closure as its starting point is not a market expecting a quick reversion.
The Arbitrage That No Longer Works
The most underappreciated consequence of an extended outage is what it does to the global pricing mechanism itself. For years the gas market has relied on arbitrage to balance itself: when Asia is short, US LNG flows east; when Europe is short, cargoes swing west. The price signal travels, and the molecules follow.
That mechanism is now partially broken. The JKM-Henry Hub spread has sat above USD 21 per MBtu — wide enough, in a normal market, to pull every available US cargo toward Asia. But the arbitrage is closed because the physical route is compromised and the freight bill has exploded. A US exporter staring at a USD 22-per-MMBtu spread must subtract USD 300,000-a-day charter rates, war-risk premiums, and weeks of additional transit time. The spread that should have equilibrated the market instead sits there, a monument to friction.
This is the second-order effect the headline price misses: the market is not just tighter, it is less efficient. Regional prices can diverge for longer because the mechanism that normally closes the gap is impaired. Volatility persists after the initial shock fades, and buyers can no longer rely on the global market to rescue them. Each region is forced to hold more inventory as self-insurance.
Japan illustrates the point. The industry ministry reported LNG inventories for power generation at 2.43 million tonnes as of September 6, up slightly week over week — but a country that once relied on just-in-time Gulf deliveries is now rebuilding buffers because just-in-time is no longer credible. Europe is doing the same: underground gas storage stood at 67.8 percent full on September 11, up from 66.4 percent the prior week, yet still 15.7 percent below the same period last year and 19.6 percent below the five-year average. Both regions are stockpiling not because they expect to run short tomorrow, but because they no longer trust the delivery schedule.
The Counter-Thesis: The Market Already Adjusted
The strongest argument against the structural view is also the most data-driven: the volumes have already been replaced. US exporters plugged the Qatar-sized hole within months. Global LNG exports hit a record in the first four months of the year. Plaquemines is ramping, Australia is producing, and new US Gulf Coast capacity is coming online. If the strait reopens — and the IEA's base case assumes it does this quarter — Qatari volumes return on top of a non-Gulf supply base that has already expanded to fill the gap. The result would be a glut, not a shortage, and prices would fall faster than they rose.
The argument has real force. Freight rates have retreated from their early-March peaks toward the USD 100,000-a-day range in some assessments, and transits, while still in single digits, have shown tentative signs of life: a Japan-linked LNG tanker crossed the strait in April for the first time since the conflict began, and Mitsui O.S.K. Lines confirmed its vessels transited without paying the tolls Tehran had proposed, asserting free navigation under international law.
"This is a principle of navigation based on international law, and we are adhering to it," Mitsui O.S.K. Lines President Jotaro Tamura said in an April interview, asked whether the company would pay proposed transit fees.
The passage matters because it shows the strait is not hermetically sealed — it is contested, negotiated, and partially permeable. A negotiated normalization, even a fragile one, would restore enough flow to collapse the fear premium.
But the counter-thesis rests on a specific and fragile assumption: that reopening equals normalization. It does not. Even if the strait reopens to pre-conflict transit levels, the insurance premiums, the route diversification, the inventory buffers, and the renegotiated contracts do not simply reverse. The 2022 gas crisis taught the market that a single winter of scarcity rewrites procurement playbooks for a decade. The buyers who lived through February 2026 are making the same calculation.
The falsifying signal is clear and quantifiable. If Hormuz transits sustainably return to more than 50 vessels a day for two consecutive weeks — roughly half the pre-conflict range of 90 to 110 — and JKM falls back below USD 18 per MBtu, the structural thesis is wrong: the market would have confirmed a cyclical shock with a clean reversion. Until then, the burden of proof sits with the normalization camp.
Three Horizons, Three Scenarios
Short term, through the end of 2026: volatility dominates. Winter demand in Asia and Europe arrives on top of a market with impaired routing and thin spot tonnage. JKM at two-and-a-half-year highs is not the ceiling if a supply incident coincides with peak heating demand. Watch weekly JKM prints and Japanese inventory draws through December.
Medium term, 2027: the market splits into three paths. In the base case, the strait remains partially open and Qatari volumes return gradually, keeping prices elevated but stable — JKM in the low-to-mid USD 20s per MBtu, freight holding above pre-crisis norms. In the downside case for prices, a durable reopening floods the market with restored Gulf supply on top of expanded US capacity, and the 2022-style scramble reverses into a 2027-style surplus. In the upside case, the outage extends through 2027 as Mitsui O.S.K. Lines warns, and the USD 30s become the new floor rather than the panic peak.
Long term, to 2050: the direction is up regardless. The annual LNG outlook from Shell expects global LNG demand to rise by around 65 percent by 2050, driven by Asia's coal-to-gas switching and data-center power demand. The Hormuz disruption does not change that trajectory — it changes who gets paid to serve it. Suppliers outside the Gulf, and the shipping companies that can offer route flexibility, capture the reliability premium.
The asymmetry for buyers and investors is clear. The exposed are the long-term off-takers locked into Gulf-linked contracts without adequate force majeure or rerouting provisions, and the European utilities still running storage about 20 percentage points below their five-year average as winter approaches. The beneficiaries are the non-Gulf exporters with spare capacity, the LNG carriers with flexible spot exposure, and the insurers pricing war risk into a market that has learned it cannot unlearn.
The final judgment is uncomfortable for anyone seeking a clean cyclical story. The strait may reopen. Transits may recover. Prices may fall from their September highs. But the market that emerges on the other side will not be the market that existed in February 2026. The Strait of Hormuz was once the world's most consequential maritime risk because of what could not be rerouted if the flow stopped. Now the world knows what that looks like — and the price of that knowledge is embedded in every LNG contract signed from here.
