Given the long list of problems that have emerged in banks over the past several years, it is time to consider performance bonds for bankers. Performance bonds are used to ensure that appropriate actions are taken by a party when monitoring or enforcement is expensive. A simple example is a security deposit on an apartment rental. The risk of losing the deposit motivates renters to take care of the apartment, relieving the landlord of the need to monitor the premises. Although not quite as simple as a security deposit, performance bonds for bankers could provide more incentive for bankers to take better care of our financial system.
