The duration of the current instability is in marked contrast to financial shocks of recent decades — stock market crashes, bond market disruptions, the 9/11 attacks — when the central bank was able to contain market problems quickly with little or no interruption of U.S. economic growth. Depending on how soon normal market conditions are restored, and at what cost, policy makers may consider whether regulators have access to adequate information about market conditions, and whether currently unregulated market participants should be subjected to disclosure and reporting requirements. In addition, the social costs of failed financial speculation may be judged great enough to warrant new restrictions designed to lower the incidence of losses that have system-wide impacts or to put the markets and the economy in a better position to weather such shocks.
