Legitimate letters of credit are never sold or offered as investments. They are issued by banks to ensure payment for goods shipped in connection with international trade. Payment on a letter of credit generally requires that the paying bank receive documentation certifying that the goods ordered have been shipped and are en route to their intended destination. Letters of credit frauds are often attempted against banks by providing false documentation to show that goods were shipped when, in fact, no goods or inferior goods were shipped.
Other letter of credit frauds occur when con artists offer a “letter of credit” or “bank guarantee” as an investment wherein the investor is promised huge interest rates on the order of 100 to 300 percent annually. Such investment “opportunities” simply do not exist.
