## Highlights

The September 11, 2001, terrorist attacks exposed the vulnerability of U.S. financial markets to wide-scale disasters. Because the markets are vital to the nation's economy, GAO's testimony discusses (1) how the financial markets were directly affected by the attacks and how market participants and infrastructure providers worked to restore trading; (2) the steps taken by 15 important financial market organizations to address physical security, electronic security, and business continuity planning since the attacks; and (3) the steps the financial regulators have taken to ensure that the markets are better prepared for future disasters.
