Ethanol put options give a buyer exposure to falling futures prices. Follow one contract from premium paid to its result at expiration.
How ethanol options work
The examples use options on denatured fuel ethanol futures. A call gives the right to enter a long futures position at the strike price. A put gives the right to enter a short futures position at that price.
A fuel blender may use ethanol calls to manage purchase costs. These examples use the newer NYMEX contract, not the legacy CBOT ethanol contract.
The cost of one option
One NYMEX contract represents 42,000 gallons. At a premium of $0.1 per gallon, one option costs $4,200 ($0.1 × 42,000).
Assume the futures price and strike are both $2 per gallon. The call and put premiums are each $0.1 for comparison, not current quotes. Results below are at expiration, before fees, with any futures position from exercise immediately closed at the stated price.
Buying ethanol puts
If you expect prices to fall instead, buying one $2 put costs $4,200 in this example.
At a futures price of $1.7 per gallon, selling at the strike gives an advantage of $0.3 per gallon. The option is worth $12,600 at expiration, leaving a $8,400 net profit after the premium.
At $2 or above, the put expires worthless. Breakeven is $1.9 per gallon. At $1.95, the price has fallen, but the put still loses $2,100: the move has not covered its premium.
Before expiration
An option can be sold to close before expiration when a market is available. Its price then includes the effect of remaining time and implied volatility, so an earlier trade need not break even at the expiration price calculated above.
The purchased option can lose its whole premium. Exercise can create a futures position requiring margin and exposing you to further gains or losses. An uncovered seller can lose more than the premium received.
