I've noticed that both the variation between crude and jet fuel prices and between delivery points for jet fuel prices varies from day to day. So I'm not sure looking at one specific day gives very good guidance.
Agreed. It's probably accurate to two significant digits, though.
Supposedly the better correlation is why heating oil is used to hedge jet fuel much more than crude is. I'll let you explain the meaning of that to me.
The simplest way of describing that is to say that if heating oil rises by 10%, then there's a 95% chance of JetA rising by 10% +/- a small margin.
The reasons for having any correlation divergence (i.e., a correlation < 100%) are:
- Product mix options. This impacts the supply, because the producers can choose to slightly vary the output from a unit of crude to bias toward particular products.
- Secondary refining capacity. This impacts the supply, in a similar fashion to the product mix options. With a given refining capacity, the secondary refining equipment can be used for different products, depending on projected demand.
- Seasonal demand fluctuations. Heating oil isn't particularly popular in the mid-summer months, but it's used a lot in January.
- Unexpected supply and demand fluctuations. Maybe a JetA pipeline breaks, which would increase the price of JetA due to supply reduction. The same wouldn't have happened to heating oil.
So you use puts and calls on heating oil to counter the effects of changing JetA prices. Basically, you set up contracts such that if heating oil prices rise, you make money. The money you make is used to offset the increased cost in buying JetA.
The downside, of course, is that if heating oil prices fall, you have to pay the other party in the heating oil contract. You'd do this with money that you had otherwise expected to spend on JetA.
The real benefit, and thus the primary motive for entering into these contracts in the first place, is predictability. If you budget very carefully, then elements of unpredictability make it harder for you to maximize your mid-term investments. You have to keep some in liquid form just in case the unexpected happens. Since fuel is such a huge portion of an airline's expenses, having predictability in future fuel costs gives you a much better opportunity to solidify a big chunk of cash for the duration of the hedges. This typically gives you a higher rate of return, since (in general) longer duration investments pay higher interest rates.
This approach works best when interest rates are relatively stable, since you don't want to be caught with a mid-term locked rate and suddenly rising spot rates. Of course, interest rates have been remarkably stable for many years, and don't show indications of a sharp rise in the mid-term. In the long term...well, that's for another day.
