Worry and its relatives, distrust, skepticism and risk aversion, are essential ingredients in a safe financial system. Worry keeps risky loans from being made, companies from taking on more debt than they can service, portfolios from becoming overly concentrated, and unproven schemes from turning into popular manias. When worry and risk aversion are present as they should be, investors will question, investigate and act prudently. Risky investments either won’t be undertaken or will be required to provide adequate compensation in terms of anticipated return.
