Jet fuel is the kerosene-based aviation fuel used by virtually all commercial and military jet aircraft. Global consumption is approximately 7 to 8 million barrels per day in normal conditions, making it one of the larger refined product markets in the world by volume. Despite this scale, jet fuel is unusual in the energy complex for not having a deeply liquid, exchange-traded futures contract. Price discovery operates through physical assessment markets, swaps, and indirect hedging via the closely related diesel and gasoil contracts.
The aviation industry's exposure to jet fuel costs is enormous — fuel is typically the largest single operating expense for commercial airlines, often accounting for 20 to 30% of operating costs and rising as a share when fuel prices spike. Understanding jet fuel pricing is essential to understanding airline economics, the financial pressures behind ticket prices, and the structural reasons why some carriers hedge aggressively while others do not.
Specifications
Commercial jet fuel is overwhelmingly Jet A or Jet A-1 specification — a kerosene-based product with tight controls on freezing point, flash point, sulfur content, and a range of other parameters required for safe high-altitude operation. The two specifications are very similar; Jet A-1 has a lower maximum freezing point (-47°C vs -40°C for Jet A) and is the dominant specification outside the United States, while Jet A predominates within the U.S. domestic market.
Military aviation uses related specifications — JP-8 in U.S. military and NATO usage, JP-5 for naval aviation — which differ from commercial Jet A-1 in additives and minor specification details. Sustainable Aviation Fuel (SAF) — synthetic kerosene produced from biomass, waste streams, or power-to-liquid processes — is a growing but still small share of the global jet pool, certified for blending with conventional jet at up to 50% in most jurisdictions.
At the molecular level, jet fuel sits in the middle distillate range — between gasoline (lighter) and diesel/gasoil (similar molecular weight but different finishing). The kerosene cut that becomes jet fuel can also be used for diesel, heating, or industrial applications. This molecular similarity to diesel is the structural reason why refiners can shift production between the two and why jet and diesel prices track closely.
The Singapore Jet Kerosene Assessment
The single most important jet fuel price reference globally is the Singapore Jet Kerosene assessment, published daily by Platts based on observed physical cargo trades in the Singapore market. Singapore is the central trading hub for Asian refined products and serves as the price discovery point for the world's largest jet fuel consuming region.
The Singapore assessment is quoted in dollars per barrel and is the reference for substantial Asian airline jet fuel procurement contracts. Singapore Jet swaps — financial instruments that settle against the Platts assessment — are actively traded and form the backbone of Asian jet hedging.
Other regional jet benchmarks include:
- Jet CIF NWE — Northwest European jet kerosene, delivered into the Amsterdam-Rotterdam-Antwerp hub. The European jet benchmark.
- U.S. Gulf Coast jet — Pipeline-delivered jet fuel from U.S. Gulf refining. The U.S. domestic jet benchmark.
- U.S. East Coast jet — New York harbor pipeline jet fuel.
These regional assessments track each other on freight-adjusted bases. When one regional jet price moves substantially out of line with another after accounting for freight, arbitrage cargoes flow between regions to restore equilibrium.
Why There Is No Deep Jet Futures Market
Several attempts have been made to launch exchange-traded jet fuel futures contracts. NYMEX listed a kerosene-type jet fuel futures contract that never achieved meaningful liquidity. ICE has listed jet fuel contracts with similar limited success. The reasons are structural:
Specification complexity. Jet fuel has tighter specifications than most petroleum products, with multiple specifications globally (Jet A, Jet A-1, military variants). Designing a single deliverable specification that satisfies airline buyer needs is difficult.
Storage constraints. Jet fuel storage requires specialized facilities. The deliverable infrastructure that would support a deeply liquid physical futures contract has been a chronic obstacle.
Existing hedging alternatives. Airlines have made the diesel-via-ULSD or gasoil cross-hedge work well enough that they have not strongly demanded a dedicated jet contract. The cross-hedge introduces basis risk but is workable.
Concentrated buyer base. Airlines are a relatively small number of large, sophisticated buyers. Bilateral physical contracts and OTC swaps suffice for their hedging needs without requiring exchange-traded futures.
The result is a market with active swap trading against PRA-published assessments rather than open-outcry or screen-traded futures.
Airline Hedging Practices
Airline jet fuel hedging strategies vary enormously across carriers:
Aggressive hedgers — Historically Southwest Airlines and some European carriers — maintain forward hedge positions covering 30 to 70% of fuel exposure over 1 to 3 year horizons. These positions can produce significant gains during fuel price spikes (Southwest famously made billions on hedges during the 2008 oil rally) but can produce equally significant losses during fuel price collapses.
Moderate hedgers — Many flag carriers and large U.S. carriers — hedge 20 to 50% of forward fuel exposure over 6 to 18 month horizons, with the goal of smoothing cost volatility rather than taking strong directional positions.
Minimal or no hedgers — Some U.S. carriers and a growing share of global airlines — choose not to hedge fuel directly, on the view that fuel cost variance can be passed to consumers through fare adjustments and that hedging costs (including margin requirements and mark-to-market accounting complexity) outweigh benefits.
Hedge instruments used include Singapore Jet swaps (for Asian operations), Jet CIF NWE swaps (for European operations), ULSD futures with jet-diesel basis adjustments (for U.S. operations), Brent or WTI futures with broader crack basis (for the simplest macro hedges), and customized OTC options structures (collars, fixed-price contracts with caps, etc.).
The Jet-Diesel Switch
One of the most operationally important features of the distillate complex is the refining capacity to shift yield between jet fuel and diesel on relatively short notice. Both products derive from the kerosene cut of the crude barrel, and refineries can adjust fractionation and treating to favor one over the other depending on relative margins.
The jet-diesel differential — the price of Singapore jet vs Singapore gasoil, or Jet CIF NWE vs ICE Gasoil — is one of the cleanest signals of which product is in tighter supply at any given moment. When jet trades at a premium, refiners pull yield toward jet, tightening diesel; when diesel trades at a premium, refiners pull yield toward diesel, tightening jet.
The relationship is one of the most important micro-structures in the global distillate market and is closely watched by refining analysts, airline fuel managers, and trucking-sector hedge providers alike.
Sustainable Aviation Fuel
Sustainable Aviation Fuel (SAF) is synthetic jet fuel produced from non-petroleum feedstocks — used cooking oil, animal fats, agricultural residues, municipal waste, or via power-to-liquid processes using renewable electricity, water, and captured CO2. SAF can be blended with conventional jet fuel up to 50% under current certification, with the blend operating as drop-in fuel in conventional aircraft.
SAF currently represents less than 1% of global jet fuel consumption but is growing rapidly under regulatory pressure. The European Union's ReFuelEU Aviation regulation mandates rising minimum SAF blending shares — 2% in 2025, rising to 70% by 2050. Similar programs are advancing in the United Kingdom, the United States, and several Asian markets.
SAF prices are typically 2 to 5 times higher than conventional jet on a per-gallon basis, reflecting limited production capacity and high feedstock costs. The cost differential is absorbed through a combination of carrier pass-through to passenger fares, government subsidies, and corporate sustainability programs that pre-purchase SAF certificates.
What Drives Jet Fuel Prices
Crude oil. Absolute jet prices track Brent and WTI on near-one-for-one bases, with the jet crack absorbing residual variance.
Aviation demand. Passenger and cargo aviation activity drive jet demand. Post-COVID demand recovery has been the principal demand-side driver of the past several years.
Refining yield decisions. Refiners shifting between jet and diesel production based on relative cracks.
Asian jet demand. The Singapore jet market is heavily exposed to Chinese, Japanese, and Korean aviation. Asian travel patterns drive much of the global jet fuel balance.
European mandates. ReFuelEU and similar policies tighten the supply of conventional jet at the margin and create incremental demand for SAF.
Refinery outages. Unplanned downtime at major distillate refineries tightens jet supply rapidly.
Diesel crack dynamics. Strong diesel cracks pull refining yield toward diesel and away from jet, tightening jet supply.
Jet Fuel in One Sentence
Jet fuel is the kerosene-based aviation fuel powering global air travel — a market with substantial physical volume but no deeply liquid futures contract, where price discovery operates through PRA-assessed regional benchmarks (notably Singapore Jet Kerosene) and where airlines hedge primarily through OTC swaps and cross-hedges against ULSD or gasoil.
