Why gasoline is rising faster than crude oil

Amid tension in energy markets, one detail stands out: gasoline prices are rising faster than the crude oil they're made from. The explanation isn't speculation, but a technical concept known as the crack spread.

What is the refining margin?

The crack spread is, essentially, the difference between the price of crude oil and the price of refined products derived from it, such as gasoline or diesel. When that gap widens, it means refineries are earning more from turning crude into fuel than oil producers earn from extracting it.

Several factors can widen that margin: available refining capacity, seasonal fuel demand, or specific disruptions in the supply of already-refined products, which are harder to quickly replace than raw crude. During periods of geopolitical tension in areas key to oil transport, this mismatch between crude and refined products tends to become more pronounced.

For consumers, this translates into a concrete effect: the price at the pump doesn't always move at the same pace as headlines about the price of a barrel of oil. Understanding this distinction helps explain why, in certain periods, filling up the tank seems to get pricier faster than crude oil headlines suggest.
