Crack Spread: A Vital Market Signal in the Oil and Petroleum Industry

The concept of a "crack spread" may sound perplexing to many, but it plays a vital role in the oil and petroleum industry. In this guide, we will delve into what a crack spread is, how it is used to hedge price risks, and how it serves as a valuable market signal.


A crack spread is essentially the difference in pricing between a barrel of crude oil and the various petroleum products refined from it. To comprehend this better, let's break down some fundamental aspects:

The Components

  • Crude Oil: The starting point of the process, crude oil, is broken down into several component products.
  • Component Products: These include gases such as propane, heating fuel, gasoline, light distillates like jet fuel, intermediate distillates like diesel fuel, and heavy distillates such as grease.

Pricing Differences

The prices of a barrel of crude oil and its refined products are not always perfectly synchronized. Various factors, including the time of year, weather conditions, global supplies, and more, can lead to fluctuations in the prices of these products. These price changes can have a significant impact on the profit margins for refiners.

Using a Crack Spread to Hedge Price Risk

Refiners employ various strategies to hedge against these price risks. These strategies often involve the use of futures contracts to lock in profit margins. Let's explore how this is done:

Traditional Hedge

  • Refiners purchase oil futures and offset their position by selling futures of the petroleum products they will be producing from the barrels.
  • The objective is to ensure a strong positive spread between the price of a barrel of oil and the price of its refined products. This implies that a barrel of oil should be notably cheaper than refined products.
  • For instance, if the price of a barrel of crude oil is $51.02 and RBOB gasoline futures are priced at $1.5860 per gallon, a refiner gets $66.61 for every barrel of gasoline. This results in a crack spread of $15.59, which can be secured through futures contracts. This is commonly referred to as the 1:1 crack spread.
  • It's important to note that this is a simplified representation, as the refining process does not yield an exact one-to-one ratio between crude oil and gasoline.

Alternate Strategies

  • Refiners may opt for other crack spread plays, such as the 3:2:1 crack spread or the 5:3:2 crack spread, depending on their specific refining processes and objectives.
  • The 3:2:1 crack spread, for example, involves buying three oil futures and matching the distillates mix more closely, such as two barrels worth of gasoline contracts and one worth of heating oil.

Trading a Crack Spread

Trading a crack spread typically involves either buying or selling it. Here's how it works:

Buying the Crack Spread

Buying the crack spread implies an expectation that the spread will strengthen. This means that refining margins are growing, usually due to falling crude oil prices or increasing demand for refined products.

Selling the Crack Spread

On the other hand, selling the crack spread indicates an expectation that the demand for refined products is weakening or that the spread itself is narrowing due to changes in oil pricing. In this case, refined product futures are sold, and crude futures are bought.

Reading the Crack Spread as a Market Signal

Even if you aren't actively trading the crack spread, it can serve as a valuable market signal with insights into potential price movements in both the oil and refined product markets. Here's how:

  • Widening Crack Spread: If the crack spread widens significantly, indicating that the price of refined products is outpacing the price of oil, this is often interpreted as a signal that crude oil prices will eventually rise to restore historical norms in the spread.
  • Tightening Crack Spread: Conversely, when the crack spread tightens too much, it signifies that refiners may reduce production to balance supply and demand, which can lead to higher crude oil prices.


Understanding the concept of a crack spread is crucial for participants in the oil and petroleum industry. It represents the price difference between crude oil and its refined products and serves as a valuable market signal. Refiners can effectively manage their profit margins by hedging price risks and utilizing various strategies, such as futures contracts. Moreover, trading the crack spread enables investors to capitalize on price movements and market trends. Whether actively trading or using it as a market signal, the crack spread provides insights into the dynamics of the oil and refined product markets.
