Costless Collars Explained: How Energy Collars Work | Mobius

QUICK ANSWER

A costless collar combines a bought option and a sold option so their premiums roughly offset, bounding a price between a floor and a cap for little or no upfront cost. A producer buys a floor and sells a cap; a buyer buys a cap and sells a floor. In exchange for free protection, you give up the favorable move beyond the sold strike.

The collar is the workhorse of energy hedging because it solves a real budget problem: how to get downside protection without paying an option premium. The trade-off is that you surrender some of the upside to fund it.

How does a costless collar work?

A collar pairs two options at different strikes. One is bought for protection; the other is sold to pay for it. The strikes are chosen so the premiums approximately cancel, which is what makes the structure “costless.” The result is a price that floats freely within a band and is fixed at the edges.

What are the parts of a collar?

The graphic below breaks a collar into its components and shows how each behaves as prices move.

The key point is that “costless” does not mean free — the cost is the upside you give up beyond the sold strike. A collar simply moves the cost from an upfront premium to a capped opportunity.

When should you use a collar?

Collars fit hedgers who want protection but cannot or prefer not to pay a premium, and who are willing to give up part of a favorable move. Producers use them to protect cash flow; buyers use them to cap costs. They are especially common when option premiums are expensive because volatility is high.
