Consumer use of bank overdraft protection has risen rapidly over the past decade, leading to increased scrutiny and the imposition of new regulations. Public and political debate regarding overdraft protection has highlighted anecdotal stories about irresponsible college students who overdraw their accounts to buy a cup of coffee, thereby triggering substantial overdraft fees. But there has been little systematic examination of the safety and soundness or consumer protection issues implicated by the increased use of overdraft protection. Available evidence indicates that those who rely on overdraft protection tend to have low credit ratings and use overdraft protection to maintain short-term liquidity because it is less expensive and more convenient than available alternatives. These alternatives include other credit options, such as payday lending, or options such as bounced checks or dishonored payments, the latter of which may result in eviction or termination of utilities or other services. There is no evidence that those who use overdraft protection are unaware of the cost or otherwise use overdraft protection foolishly or unknowingly. In addition, there is no evidence that banks are earning economic rents off the issuance of overdraft protection, as increases in overdraft revenues have been offset by dramatic increases in free checking, improved quality, and free services offered to bank customers. A serious reduction in overdraft revenues would reverse all of these trends and result in many consumers being driven out of the mainstream financial system, especially low-income consumers. Absent a demonstrable market failure or demonstration of systematic consumer abuse, restriction on consumer choice of overdraft protection would likely impose substantial costs on consumers and banks with minimal gains.
