Jet-fuel crack spread

The price difference between a barrel of crude oil and the refined jet fuel produced from it, representing refining margins.

The jet-fuel crack spread is a key commodity pricing metric that represents the market premium or refining margin for processing crude oil into aviation-grade jet fuel. It measures the difference between the price of a barrel of crude oil and the price of the refined jet fuel produced from it. Because crude oil must undergo complex refining processes to become usable jet fuel, this spread reflects the supply, demand, and operational dynamics of the refining sector rather than just the price of raw energy. To calculate the spread, market participants compare the spot price of refined jet fuel (often quoted in gallons or metric tons and converted to barrels) against a benchmark crude oil price, such as West Texas Intermediate (WTI) or Brent. The spread fluctuates based on global refining capacity, seasonal travel demand, refinery maintenance schedules, and the relative yield of other middle distillates like diesel and heating oil, which compete for the same refining capacity. For airline and transportation investors, the jet-fuel crack spread is a critical variable because fuel is typically an airline's largest or second-largest operating expense. A widening crack spread means airlines are paying a steep premium to refiners, which can inflate fuel costs and compress operating margins even if crude oil prices remain flat. Conversely, a narrowing spread indicates oversupplied refining capacity or weak aviation demand, which lowers fuel costs for carriers. Understanding this spread helps investors determine whether an airline's cost pressures are driven by global oil supply shocks or localized refining bottlenecks. This distinction is vital for evaluating an airline's fuel hedging strategies, pricing power, and overall earnings sensitivity to energy markets.

If Brent crude oil is trading at $80.00 per barrel and refined jet fuel is trading at $2.62 per gallon, we first convert the jet fuel price to a per-barrel basis by multiplying by 42 (since there are 42 gallons in a standard barrel): $2.62 42 = $110.04 per barrel. The jet-fuel crack spread is then calculated as $110.04 - $80.00 = $30.04 per barrel.
