Guarantee Letter

Definition

A Guarantee Letter is a formal document issued by a commercial bank to guarantee the payment of the exercise price of a client’s put option. This guarantee becomes relevant when an assignment notice, which indicates the exercise of the put option, is presented to the option seller (writer). The bank assures the seller that the exercise price will be paid on behalf of its client.

Examples

Trading Options: A client holding a put option to sell shares at a specified price ensures they get the payment even if the market price falls drastically. The bank issues a guarantee letter to assure the seller that the client can cover the agreed exercise price upon execution.
Real Estate Transactions: A real estate investor purchases a put option as a hedge against property value decline. If the investor decides to exercise the option, the bank’s guarantee letter ensures the seller receives the payment promised in the contract.
