A perfect storm of soaring equity values and historically low interest rates has sparked a borrowing binge among securities investors. Securities-based loans ("SBLs") are a very attractive product for the broker-dealers who market them. However, SBLs impose substantial risks on borrowers. These risks are easy to overlook in a buoyant market but will eventually wreak havoc on the financial wellbeing of investors who are not prepared to withstand the next bear market. In this paper, Paul Meyer reviews the types of lending in which broker-dealers engage, describes how SBLs are regulated and marketed, and points out the considerable risks borne by a customer who borrows against his savings.
