A Missouri Irrevocable Letter of Credit (IOC) is a document that guarantees payment of a specified amount of money to a beneficiary under certain conditions. It is issued by a bank on behalf of a customer (the applicant) and provides assurance of payment to the beneficiary upon presentation of documents specified in the IOC. There are two primary types of Missouri Irrevocable Letters of Credit: Standby and Commercial. Standby Blocs are typically used to guarantee payment of a debt if the borrower defaults on payment, while Commercial Blocs are used to guarantee payment to a supplier for goods or services provided. Both types require that the bank verify that the applicant has sufficient funds to cover the IOC amount before issuing the document.
