Meaning
Option structures that operate within specific price bands limit the exposure of hedgers to a defined range of market movements. Strike corridors allow companies to manage their price risk while reducing the cost of the insurance. This instrument combines several options to create a customized payoff profile.
These instruments are often used in currency and interest rate hedging.
Bound Selection
The upper and lower limits of the structure are chosen based on the risk appetite of the firm. Strike corridors define the area where the protection is active. Outside of these bounds, the hedge may expire worthless or provide only partial coverage.
This selection involves a trade-off between the level of protection and the upfront cost.
Premium Reduction
Traditional options can be expensive for businesses with tight margins. The use of strike corridors lowers the net cost by selling an option at one level to finance the purchase of an option at another. This structure can sometimes result in a zero cost hedge where no initial payment is required.
The company gives up the potential for gains beyond a certain point in exchange for cheaper protection. This strategy is effective for firms that only need to protect against moderate price shifts. The reduction in premium makes hedging accessible to a wider range of participants.
It also simplifies the budgeting process by removing the need for a large initial outlay.
Exercise Logic
The settlement of the contract depends on where the final market price sits relative to the chosen levels. Strike corridors specify whether the payout is linear or fixed once a boundary is crossed. This clarity allows the treasury department to calculate the exact impact on the balance sheet.
