Rebate Option

A rebate option is a specialized financial derivative that provides the holder with a predetermined cash payment if the underlying asset price touches or crosses a specific barrier level during the life of the contract. Unlike standard vanilla options that focus solely on the final strike price, rebate options are path-dependent, meaning the payout is triggered by the asset price behavior throughout the option's duration.

These instruments are often used by traders to hedge against volatility or to speculate on specific price movements reaching a threshold without requiring the asset to close at a certain level. In cryptocurrency markets, they are frequently embedded in structured products to manage downside risk or to enhance yield for liquidity providers.

The rebate amount is fixed at the inception of the contract and is paid out regardless of where the asset price ends up, provided the barrier condition was met. This makes them highly sensitive to the proximity of the barrier and the expected volatility of the underlying asset.

They are a core component of exotic derivative suites used to engineer specific risk-reward profiles in decentralized finance.
