Les marchés de l'énergie sont complexes, volatils et fortement interconnectés. Un indicateur clé qui aide les traders et les analystes à comprendre la rentabilité du raffinage du pétrole brut en produits pétroliers précieux est le crack spread. Essentiellement, un crack spread est un calcul qui montre la valeur marchande théorique des produits raffinés (comme l'essence, le diesel et le mazout) qui pourraient être obtenus à partir d'un baril de pétrole brut après le processus de raffinage, communément appelé « craquage ».
Qu'est-ce qu'un Crack Spread ?
En termes simples, le crack spread représente la différence entre le prix du pétrole brut et le prix des produits raffinés qui en sont dérivés. C'est un indicateur crucial de la rentabilité des raffineries car il reflète la marge que les raffineries réalisent en transformant le pétrole brut en biens commercialisables. Un crack spread plus large signale une rentabilité plus élevée pour les raffineries, tandis qu'un spread plus étroit suggère une rentabilité plus faible voire des pertes potentielles.
Il existe plusieurs types de crack spreads, chacun se concentrant sur différents produits raffinés :
Comment est-il calculé ?
Le calcul varie légèrement selon le crack spread spécifique utilisé, mais la formule générale est :
Crack Spread = (Prix des produits raffinés) - (Prix du pétrole brut)
Les prix des produits raffinés sont souvent des moyennes pondérées en fonction des rendements typiques d'un baril de pétrole brut. Ces rendements peuvent varier en fonction du type de pétrole brut et de la configuration de la raffinerie.
Pourquoi les Crack Spreads sont-ils importants ?
Les crack spreads sont essentiels pour plusieurs raisons :
Limitations :
Il est important de noter que les crack spreads sont des calculs théoriques. Ils ne tiennent pas compte de tous les coûts liés au raffinage, tels que le transport, les frais d'exploitation et la maintenance. De plus, les rendements réels des produits raffinés à partir d'un baril de pétrole brut peuvent varier.
En conclusion :
Les crack spreads sont des outils essentiels pour comprendre la dynamique du marché pétrolier. Ils offrent des informations précieuses sur la rentabilité du raffinage, le sentiment du marché et les opportunités de trading. En suivant de près les crack spreads, les investisseurs, les traders et les analystes peuvent mieux comprendre les relations complexes entre le pétrole brut et les divers produits raffinés qui stimulent notre économie mondiale.

Scenario:
Assume the following market prices:
Task:
Calculate the 3-2-1 crack spread based on the given prices and yield percentages. Show your work.
Here's how to calculate the 3-2-1 crack spread:
(0.3 * $90/barrel) + (0.2 * $85/barrel) + (0.5 * $100/barrel) = $27 + $17 + $50 = $94/barrel
$94 (Weighted Price of Refined Products) - $75 (Price of Crude Oil) = $19/barrel
Therefore, the 3-2-1 crack spread is $19 per barrel.

This chapter details the various methods used to calculate crack spreads, emphasizing the nuances and variations depending on the specific spread and the available data.
1.1 Basic Crack Spread Calculation: The fundamental calculation remains consistent across all crack spread types: Crack Spread = (Price of Refined Products) - (Price of Crude Oil). However, the complexity lies in determining the "Price of Refined Products."
1.2 Weighted Averages for Refined Products: The prices of gasoline, heating oil, and diesel aren't simply added together. They are typically weighted according to the typical yields obtained from refining a barrel of crude oil. For example, a 3-2-1 crack spread might use a weighting of 3 barrels of gasoline, 2 barrels of heating oil, and 1 barrel of diesel, reflecting the approximate output ratios of a typical refinery. These weights are not fixed and can vary based on the crude oil type and refinery configuration. The chapter would detail methods for obtaining these weights, including referencing industry averages and specific refinery data.
1.3 Alternative Weighting Schemes: Different refineries have different processing capabilities and product mixes. Therefore, alternative weighting schemes might be employed to reflect the specific output profile of a particular refinery or a group of refineries. This section will cover the development of customized weighting schemes based on refinery data and market conditions.
1.4 Incorporating Transportation Costs: The basic calculation often ignores transportation costs from the refinery to the delivery point for refined products. This chapter will explain how to incorporate these costs to arrive at a more accurate representation of refinery profitability. Different models for incorporating these costs (e.g., using location-specific prices) would be discussed.
