The $500B Disruption: From LNG to Jet Fuel and the Cost of Hormuz

Context

In late February 2026, a cascade of military events, U.S. and Israeli strikes on Iran, the reported death of Iran’s Supreme Leader, and retaliatory drone and missile attacks by the IRGC, produced a consequence that energy markets had long modeled but never truly stress-tested: the effective operational closure of the Strait of Hormuz. This narrow waterway between Iran and Oman is not merely a geographic feature. It is the circulatory system of global hydrocarbon supply. Roughly 20% of the world’s seaborne crude oil transits it daily, as does a comparable share of global liquefied natural gas, including virtually all of Qatar’s LNG exports, making it the single most consequential energy chokepoint on Earth, and previously discussed here.

The closure was not a formal naval blockade in the legal sense but functionally it amounted to one. QatarEnergy had halted LNG production entirely following strikes on the Ras Laffan and Mesaieed complexes, declaring force majeure on exports. Gulf oil producers like Saudi Arabia, Kuwait, the UAE, Iraq were beginning to face a novel and severe problem: with nowhere to send their output, onshore storage was filling rapidly, threatening forced upstream shut-ins.

Meanwhile Europe, though less exposed to Gulf crude than Asia on a direct import basis, found itself acutely vulnerable on gas. European benchmark TTF prices surged 30% to 85% in single trading sessions, reflecting the sudden removal of Qatar as a non-Russian LNG anchor. EU gas storage was already running 30% to 35% below five-year averages for this time of year, the lowest buffer since the 2022 crisis, and the summer refill season was now at serious risk. Emergency meetings were convened in Brussels; France, Germany, and others began competing aggressively for spot cargoes from the United States, Africa, and wherever uncommitted volumes could be found.

Impact on Oil, LNG, and Derivatives

The immediate market reaction confounded the most extreme forecasts. Brent crude climbed to roughly $82 to $85 per barrel, a sharp increase from pre-crisis levels but far short of the $150 to $200 scenarios that had circulated in early commentary. The relative resilience of crude prices reflected crude oil’s comparative fungibility: Saudi Arabia’s East-West pipeline and the UAE’s ADCOP bypass offer partial alternatives to the strait, and the U.S. Atlantic Basin, with abundant shale production, could swing supply westward toward Europe, even if not instantaneously.

LNG told a more acute story. Qatar’s production halt removed ~20% of global LNG supply in a matter of days, and unlike crude oil, there is no pipeline bypass for Qatari gas. TTF prices peaked intraday near €59 to 60 per megawatt-hour, with some contract-specific moves exceeding 80%. Goldman Sachs projected TTF could approach €74/MWh in a month-long disruption scenario; ICIS modeled averages of €86/MWh across a 90-day blockade, with intraday spikes above €90 realistic in tail scenarios as Figure 1 and 2 show below. The U.S. emerged as the primary swing supplier, Cheniere, Venture Global, and other American exporters saw their stock prices and spot margins surge, with flexible Atlantic Basin volumes beginning to divert toward both Europe and Asia almost immediately.

Yet the derivative that moved most violently, and that exposed the deepest structural fragility, was jet fuel.

Jet fuel crack spreads, the refining margin representing the premium of jet kerosene over crude, doubled or more within days. Asian jet cracks breached $52 per barrel, levels not seen since June 2022, while outright prices in Singapore rocketed to $225 or more per barrel. In Europe, premiums over crude hit intraday highs above $100 per barrel in swaps trading. European jet fuel outright prices reached 28-month highs, approximately $1,001 per tonne delivered to northwest Europe, up more than 20% in days. Diesel and gasoil also spiked sharply, European diesel futures climbed roughly 23%, but jet fuel consistently outpaced them in percentage terms. Analysts and physical traders alike identified jet kerosene as the most severely dislocated product in the crisis, far outrunning crude or LNG on a relative basis.

Why the Focus Falls on Jet Fuel and the Damodaran Valuation Scenarios

The disproportionate dislocation of jet fuel is not accidental. It reflects structural features of the product that make its supply chain unusually brittle under a Hormuz disruption. Approximately 18% to 20% of global jet fuel exports transit the strait, a higher proportional exposure than for crude oil on its own, and Europe sources between 25 and 50% of its jet kerosene from Gulf producers, with Kuwait as a top supplier. Unlike diesel, which has more diverse sourcing (Russia, the U.S., domestic European refining), jet fuel’s specialized specifications leave limited room for quick substitution.

Jet A-1, the global aviation standard, must meet a maximum freeze point of -47°C, a specification driven entirely by the physics of high-altitude flight, where outside temperatures routinely drop to -50°C or colder. Automotive diesel gels at temperatures well above that. There is no viable blending solution: adding diesel-like components to jet fuel would compromise low-temperature performance and is categorically prohibited under aviation certification standards. Jet fuel inventories are also held at lower buffers than crude or diesel, and the specialized storage and refining configurations required to produce it mean that non-Gulf refineries cannot quickly ramp output to replace lost volumes. When Gulf supply is cut off, the product market tightens faster and harder than crude, and it stays tight longer.

This is precisely why a Damodaran-inspired valuation lens is useful here, even if imperfect. Using a discounted cash flow approach with crisis-adjusted equity risk premiums, where the baseline cost of capital rises from 8% to 12% and growth rates turn negative under sustained disruption, two scenarios of particular relevance emerge.

The first concerns the aviation market itself. Global jet fuel is a roughly $220 to $300B annual market in 2026. A 50% price spike, consistent with observed crack spread movements, adds approximately $125B in annualized extra costs globally. If airlines absorb or pass through half of that, the implied profit erosion and multiple compression represent something on the order of $15B per month of disruption in sector value terms. Extended over three to six months, this approaches or exceeds the short-term value impact of the LNG supply shock, where U.S. flexibility partially mitigates the damage.

The second scenario concerns Gulf refining infrastructure directly. Gulf refineries collectively represent approximately 10M to 12M barrels per day of refining capacity, with normalized annual cash flows of roughly $27B at $7.50 per barrel average margin. Pre-crisis, applying a standard 8% cost of capital yields an asset value on the order of $338B. Under crisis conditions, with the cost of capital rising to 12% and growth turning negative as facilities run low or face potential strike damage, that value drops to approximately $133B, implying roughly $200B in asset devaluation. If prolonged strikes or forced shut-ins damage physical infrastructure requiring reconstruction at $20,000 to $40,000 per barrel per day of capacity, the replacement cost dimension alone could add another $200 to $300B to the global stakes.

These numbers are likely to establish the key point: jet fuel’s role as the stressed derivative, combined with the physical vulnerability of Gulf refining infrastructure, creates an economic exposure that arguably exceeds the headline crude and LNG narratives that dominated early crisis commentary.

The Lens of System Dynamics

Static valuation captures a moment. System dynamics captures a process, and the Hormuz crisis is fundamentally a process, not a snapshot. A previous article using System Dynamics is available in our archive.

A system dynamics framework models the crisis as an interconnected set of stocks (inventories, refinery throughput, price levels), flows (production rates, exports, demand), feedback loops, and delays. Applied here, it reveals several dynamics that a discounted cash flow model cannot easily surface.

The dominant reinforcing loop in the current crisis runs as follows: physical disruption to Gulf exports reduces jet fuel inventory; lower inventory drives prices higher; higher prices incentivize hoarding and accelerate competitive bidding for non-Gulf cargoes; the resulting supply competition further drains available inventory; refineries reduce throughput to preserve infrastructure, which tightens supply further. This is a self-amplifying cycle with no automatic stabilizer, it accelerates until either an external intervention breaks the loop or the system crosses a threshold into demand destruction as Figure 3 shows.

Figure 3. Reinforcing loop shows escalating cycle of jet fuel under System Dynamics

The balancing loop works in the opposite direction: high prices reduce aviation demand (flight cancellations, route cuts, cargo deferrals); reduced demand slows inventory drawdown; prices moderate. But this loop operates with significant delays. Airlines hedge their fuel positions months in advance, which insulates near-term demand from immediate price signals. The full demand response to a 50% to 150% price spike may take four to eight weeks to materialize, by which point, if the disruption persists, physical inventory may already have crossed dangerous thresholds as Figure 4 shows.

Delays compound the problem further. Rerouting non-Gulf LNG cargoes, confirmed in real time by reports of U.S. and Nigerian LNG tankers pivoting from European to Asian routes, takes one to two months in freight terms. Refinery restarts after forced slow-downs take days to weeks. Diplomatic or naval resolutions, even if agreed quickly, require additional time to translate into restored tanker traffic given lingering insurance and security concerns.

The China oil resilience literature (modeling similar chokepoint shocks) found that systems can absorb short supply disruptions, roughly 10% to 20% losses, through buffer stocks and flexible sourcing. Beyond that threshold, instability curves steepen sharply. The current Hormuz disruption, with tanker traffic down 80 to 95%, is operating far beyond that absorption capacity. In system dynamics terms, the reinforcing loops are dominant, and the key policy question is not whether the system will be stressed, but how long before it crosses irreversible thresholds.

Three scenario profiles emerge from this lens as Figure 5 shows below. In a short resolution, naval escorts restoring flows within 10 to 20 days, balancing loops reassert themselves, cumulative global stakes remain in the $50 to $100B range, and infrastructure damage is avoided. In a medium scenario, 30 to 60 days of partial escalation with some Gulf refinery damage, reinforcing loops amplify inventory drawdowns to 40% to 60% of normal, and cumulative stakes rise toward $200B to $400B, including refinery asset devaluation. In a prolonged scenario of 90 or more days with no resolution, the system crosses into demand destruction exceeding 20%, with global stakes potentially approaching $500B to $1T in combined aviation GDP impact, infrastructure replacement costs, and cascading inflation.

Consequences on Infrastructure

The most underappreciated dimension of the crisis is what might be called the “slow to save” dynamic: the deliberate decision by Gulf producers and Asian refiners to reduce throughput not for economic optimization, but to prevent irreversible physical damage to their assets.

Refineries are not simple on-off machines. Operating at very low throughput or shutting down abruptly under feedstock starvation creates serious risks: thermal stress and coking in distillation units, catalyst deactivation in hydrocrackers and hydrotreaters, corrosion and erosion from uneven operations, and mechanical failure in pumps, valves, and vacuum systems. Restarting complex units like fluid catalytic crackers, central to maximizing jet fuel yields, requires days to weeks of careful commissioning and costs millions. Prolonged idling can result in permanent derating of capacity, not merely temporary offline status.

Unfortunately the law of physics steps in. Pumps and pipes are sized for a minimum hydraulic flow. And we are talking about hundreds of pumps and thousands of pipelines in a single refinery. So refineries can only likely run to minimum 60% of their nameplate capacity, otherwise it is 0%. For more discussion on this topic, I gladly recommend June Goh from Sparta Commodities.

Upstream, the consequences are equally serious. Gulf producers, Saudi Arabia, Kuwait, Iraq, Qatar, have limited onshore tankage. With exports blocked and storage filling, the choice becomes either cutting production or risking tank overflows and safety events. Forced upstream shut-ins carry their own long-term costs: pressure drops in reservoirs, water influx, paraffin and sand accumulation in wellbores, and lost ultimate recovery rates. These are not costs that show up immediately in price indices, but they represent real, lasting damage to national asset bases. Putting all together on Figure 6 below.

Figure 6. Stock and Flow plot on Jet Fuel and refinery throughput

Chinese and other Asian refineries have already begun accelerating maintenance turnarounds, cutting run rates by 20% to 30%, or idling individual units in anticipation of prolonged feedstock scarcity. Zhejiang Petrochemical, backed by Saudi Aramco, reportedly shut a 200,000 barrel per day unit early under supply pressure. These are individually rational decisions that are collectively reinforcing, each refinery running low contributes to tighter global product supply, which drives prices higher, which validates the decision to slow down, which tightens supply further.

In the system dynamics model on Figure 7 shows that the infrastructure preservation motive introduces a feedback pathway that is neither purely reinforcing nor purely balancing: it slows the rate of system degradation in the short term by avoiding catastrophic shutdowns, but it accelerates the rate of product market tightening by reducing output, ultimately pulling the system toward the same crisis threshold by a different route. The “slow to save” dynamic buys time, but it does not change the underlying trajectory without external resolution.

Potential Solutions: Paper vs. Physical

The response architecture that emerged hours ago mapped neatly onto the distinction between paper and physical interventions, and the gap between them.

On the paper side, the most notable development was the U.S. Treasury Department’s preparation of measures to intervene directly in oil futures markets, reportedly including government participation in selling positions on NYMEX or ICE to cap speculative upside. Treasury Secretary Scott Bessent, a former macro trader with Soros Fund Management and founder of Key Square Group, brought a distinctly financial market mindset to the crisis. The logic looks coherent: if futures prices overshoot fundamentals due to fear-driven speculation, capping the paper price reduces hoarding incentives, narrows bid-ask spreads, and buys time for physical supply channels to adjust.

The limitations of this approach are equally clear. As John Kilduff noted at the time, financial intervention does not reopen Hormuz, restore tanker insurance markets, or accelerate refinery restarts. The crisis is overwhelmingly physical in origin: tankers are stranded because they face genuine attack risk and cannot obtain war-risk insurance at viable premiums, not because futures curves are mis-priced. Paper intervention can smooth out the speculative premium embedded in futures, but it cannot address the underlying supply-chain reality. In system dynamics terms, it strengthens the balancing loop as price moderation reduces hoarding behavior without touching the reinforcing loop of physical scarcity drives structural tightness regardless of paper prices.

On the physical side, the key levers are (i) naval escorts to restore tanker confidence in the strait; (ii) government-backed war-risk insurance to replace the commercial market that has effectively withdrawn; (iii) strategic petroleum reserve releases to bridge the inventory gap; and diplomatic channels to create conditions for Iranian acquiescence or at least de-escalation. Bessent’s team was simultaneously working several of these threads, naval convoy arrangements were under discussion, and government-backed insurance had been floated in CNBC interviews. The real question was timing: each of these physical mechanisms operates with delays of days to weeks, during which the reinforcing loops in the system dynamics model continue to run.

The LNG market revealed the same paper-versus-physical tension in its own terms. Atlantic Basin LNG cargoes, U.S. volumes from Plaquemines and Corpus Christi terminals, Nigerian cargoes from Bonny LNG, began diverting to Asia within days, following the physical arbitrage signal: JKM-TTF spreads and netback calculations for Asian delivery exceeded those for European delivery, making Asian routing more profitable for uncommitted volumes. This is the market’s physical self-correction mechanism, efficient, but not sufficient to replace ~20% of global supply lost from Qatar in the near term, and available only for flexible, uncommitted volumes that represent a fraction of the total market as Figure 8 shows.

Figure 8. Atlantic cargos & JKM-TTF spreads are necessary but not sufficient to replace ~20% of global supply lost from Qatar

Europe, consequently, faced a period of genuine scarcity that no financial instrument could resolve quickly. The structural lesson is one that energy markets have encountered repeatedly but tend to underweight: in physical commodity systems operating near capacity, paper tools are most effective as complements to physical measures, not substitutes for them. They can reduce noise and moderate speculative overshoot. They cannot create barrels.

Final Thoughts

  • The 2026 Hormuz disruption has confounded the most extreme predictions, no $200 crude, no LNG collapse. The real damage landed in jet fuel: crack spreads doubling to $52/barrel in Asia, European outright prices at 28-month highs, and a Gulf refinery system quietly throttling back to avoid permanent damage.

  • At stake, by conservative Damodaran estimates, is roughly $200B in Gulf refinery asset devaluation under a medium-disruption scenario, with aviation sector value erosion compounding that figure significantly if the disruption extends to three months or more. The system dynamics model shows why these numbers accelerate non-linearly: reinforcing loops dominate once inventories fall below critical thresholds, and the “slow to save” infrastructure dynamic buys time without changing the trajectory.

  • Paper solutions, Treasury futures intervention, signaling, government-backed insurance, all of them are useful bridges, not foundations. The physical levers, naval escorts, tanker insurance restoration, reservoir protection, are what determine whether this crisis leaves a temporary scar or a permanent one. The longer resolution takes, the more the distinction between the two collapses.

On To The Next One.
