What is a Knock-In Option?

A Knock-In Option is a type of exotic option in which the contract only becomes active, or “knocks in,” if the underlying asset reaches a predetermined barrier price during the option’s life. Until this barrier is breached, the option does not exist and cannot be exercised. Knock-in options are commonly used in structured finance and risk management to tailor exposure and reduce premium costs.

Example

Suppose an investor buys an up-and-in call option on Stock XYZ with a strike price of $50 and a barrier at $55. If XYZ never trades at or above $55 before expiration, the option never becomes active and expires worthless. If XYZ reaches $55, the option “knocks in” and becomes a regular call option with a $50 strike, exercisable until expiration.
