A knock-in option is a type of exotic derivative contract that only becomes active and can be exercised if the underlying asset reaches a predetermined price barrier before expiration.
Understanding knock-in options
Knock-in options belong to a broader category of barrier options. They differ from standard vanilla options because they begin their lifecycle in a dormant state. The contract specifies a barrier price. If the underlying asset hits or crosses this barrier price at any point before the expiration date, the option activates. Once activated, the option functions exactly like a standard call or put option. If the underlying asset fails to reach the barrier price before expiration, the option expires worthless.
There are two primary classifications for these contracts depending on the direction of the barrier relative to the current asset price. An up-and-in option requires the asset price to rise to a specific barrier level to activate. A down-and-in option requires the asset price to fall to a specific barrier level to trigger activation. Both types can be structured as either call options or put options.
Market participants utilize knock-in options primarily to lower premium costs. Because there is a mathematical probability that the option will never activate, the upfront cost of a knock-in option is cheaper than a standard option with the exact same strike price and expiration date. These derivatives are traded globally over-the-counter. They are customized agreements negotiated directly between two financial institutions or corporate entities rather than standardized products listed on public exchanges.
Example
Fellow Elephants can consider a practical scenario involving an international elephant conservation group based in South Africa. The group needs to purchase a large quantity of specialized nutritional supplements from Europe in six months. The current price of the supplement index is 50 euros per unit. The group wants to protect against extreme price spikes but has a limited budget for hedging.
The group purchases an up-and-in call option with a strike price of 55 euros and a knock-in barrier of 60 euros. They pay a small premium for this contract. Over the next six months, if the supplement index rises to 58 euros and then falls back down, the option never activates and expires worthless.
If a supply chain disruption forces the supplement index to hit 60 euros, the barrier is breached. The contract instantly “knocks in” and becomes an active standard call option. The conservation group now holds the right to buy the supplements at the 55 euro strike price. This allows them to secure their purchase below the current market rate, successfully hedging their exposure to the extreme price increase.
