Factors affecting the crack spread

One of the most important factors affecting the crack spread is the relative proportion of various petroleum products produced by a refinery. Refineries produce many products from crude oil, including

and others. To some degree, the proportion of each product produced can be varied in order to suit the demands of the local market. Regional differences in the demand for each refined product depend upon the relative demand for fuel for heating, cooking or transportation purposes. Within a region, there can also be seasonal differences in demand for heating fuel versus transportation fuel. The mix of refined products is also affected by the particular blend of crude oil feedstock processed by a refinery, and by the capabilities of the refinery. Heavier crude oils contain a higher proportion of heavy

For independent oil refiners which purchase crude oil and sell refined products in the wholesale market, adverse price movements can present a significant economic risk. Given a target optimal product mix, an independent oil refiner can attempt to hedge itself against adverse price movements by buying oil

Refiners’ profits are tied directly to the spread, or difference, between the price of crude oil and the prices of refined products. Because refiners can reliably predict their costs other than crude oil, the spread is their major uncertainty. One way in which a refiner could ensure a given spread would be to buy crude oil futures and sell product futures. Another would be to buy crude oil

s. Both of those strategies are complex, however, and they require the hedger to tie up funds in margin accounts. To ease this burden, NYMEX in 1994 launched the crack spread contract. NYMEX treats crack spread purchases or sales of multiple futures as a single trade for the purposes of establishing margin requirements. The crack spread contract helps refiners to lock-in a crude oil price and heating oil and unleaded gasoline prices simultaneously in order to establish a fixed refining margin. One type of crack spread contract bundles the purchase of three crude oil futures (30,000 barrels) with the sale a month later of two unleaded gasoline futures (20,000 barrels) and one heating oil future (10,000 barrels). The 3-2-1 ratio approximates the real-world ratio of refinery output—2 barrels of unleaded gasoline and 1 barrel of heating oil from 3 barrels of crude oil. Buyers and sellers concern themselves only with the margin requirements for the crack spread contract. They do not deal with individual margins for the underlying trades. An average 3-2-1 ratio based on sweet crude is not appropriate for all refiners, however, and the OTC market provides contracts that better reflect the situation of individual refineries. Some refineries specialize in heavy crude oils, while others specialize in gasoline. One thing OTC traders can attempt is to aggregate individual refineries so that the trader’s portfolio is close to the exchange ratios. Traders can also devise swaps that are based on the differences between their clients’ situations and the exchange standards.
