Understanding and monitoring differentials is vital for effective trading and risk management. Hedgers can use key differentials like crack spreads (e.g. Ebob Gasoline vs Brent) or geographical arbitrages (e.g. Sing 380 vs 3.5% Barges) to lock in profit margins on their operations and ensure they’re protected from adverse movements in prices.

Understanding differentials in oil trading
What Are Oil Price Differentials?
In the oil markets, a differential is the price difference between two contracts, such as WTI vs Brent or Jet Fuel vs Gasoil. These differentials are crucial for traders, refiners, consumers and producers, as they influence physical flows, hedging decisions, and profitability.
Oil price differentials arise due to variations in product specifications (e.g., API gravity, sulfur content) and logistical factors (e.g., transportation costs, regional supply and demand). For instance, a heavy, sour crude oil located far from major refining centers may trade at a discount relative to a light, sweet crude oil situated near key markets.
Key Factors Influencing Differentials
- Product Quality: Differences in the quality of product the benchmarks in the differential refer to. For example, the 0.5% Sulfur Fuel Oil vs 3.5% Sulfur Fuel oil differential trades at a positive price due to 0.5% Fuel being more valuable.
- Location and Transportation: The proximity of oil and products to demand hubs and export terminals impacts transportation costs and, consequently, differentials. Oil and products located in remote areas or regions with limited infrastructure may incur higher transportation costs, widening the differential.
- Market Dynamics: Regional supply and demand imbalances, geopolitical events, and infrastructure constraints can cause differentials to fluctuate. For example, pipeline bottlenecks or refinery outages can lead to significant changes in local differentials.
Examples of Common Differentials
Crack Spread Differentials
Crack spread differentials are composed of a refined product leg vs a crude oil leg. These differentials represent the indicative refining margin for the refined product vs the crude benchmark and are the most liquid differential in derivative markets. Traders often use these contracts, not just to hedge, but to also speculate on the strength of the refined product market relative to the underlying crude oil.
Example:
Jet Fuel Crack Spread: the difference between the price of the Jet fuel and Brent crude oil.
Interproduct Differentials
Interproduct differentials are usually composed of two different products, but of the same tenor. They could represent a quality or specification differential within a product group like High Sulphur Fuel vs Low Sulphur Fuel, or they could represent a spread between two separate product groups like Gasoline vs Naphtha or Low Sulphur Fuel vs Gasoil.
Example:
Naphtha vs Gasoline Spread: The difference between the price of gasoline and the price of Naphtha.
Intra-product Differentials
The two legs composing the differential spread are related to the same product type but with different quality and/or properties. Among the most liquid and traded contracts in this category are the marine fuel quality spreads.
Example:
Low Sulphur Shipping Fuel Vs High Sulphur Shipping Fuel: the difference between the price of the marine fuel with low sulphur content and marine fuel with high sulphur content.
Geographical Differentials
The two legs composing the differential spread are related to the same product and quality but delivered in different key world regions. Among the most used contracts here we find the East/West contracts on Gasoline, Gasoil and Marine fuel. These contracts are used to capture the difference in price of these products delivered in key hubs in the Easter region of the world, like Singapore, and in key hubs in the West like Rotterdam.
Example:
Singapore Gasoline vs European Gasoline
