Beginning in 2007, U.S. financial conditions deteriorated, leading to the near-collapse of the U.S. financial system in September 2008. Major commercial banks, insurers, government-sponsored enterprises, and investment banks either failed or required hundreds of billions in federal support to continue functioning. Households were hit hard by drops in the prices of real estate and financial assets, and by a sharp rise in unemployment. Congress responded to the crisis by enacting the most comprehensive financial reform legislation since the 1930s. Then-Treasury Secretary Timothy Geithner issued a reform plan in the summer of 2009 that served as a template for legislation in both the House and Senate. After significant congressional revisions, President Obama signed H.R. 4173, now titled the Dodd-Frank Wall Street Reform and Consumer Protection Act (P.L. 111-203), into law on July 21, 2010. Perhaps the major issue in the financial reform legislation was how to address the systemic fragility revealed by the crisis. The Dodd-Frank Act created a new regulatory umbrella group chaired by the Treasury Secretary, the Financial Stability Oversight Council (FSOC, with authority to designate certain financial firms as systemically important and subjecting them and all banks with more than $50 billion in assets to heightened prudential regulation. Financial firms were also subjected to a special resolution process (called "Orderly Liquidation Authority") similar to that used in the past to address failing depository institutions following a finding that their failure would pose systemic risk. The Dodd-Frank Act made other changes to the regulatory structure. It created the Office of Financial Research to support FSOC. The act consolidated consumer protection responsibilities in a new Bureau of Consumer Financial Protection (CFPB). It consolidated bank regulation by reassigning the Office of Thrift Supervision's (OTS's) responsibilities to the other banking regulators. A federal office was created to monitor insurance. The Federal Reserve's emergency authority was amended, and its activities were subjected to greater public disclosure and oversight by the Government Accountability Office (GAO). Other aspects of Dodd-Frank addressed particular sectors of the financial system or selected classes of market participants. Dodd-Frank required more derivatives to be cleared and traded through regulated exchanges, reporting for derivatives that remain in the over-the-counter market, and registration with appropriate regulators for certain derivatives dealers and large traders. Hedge funds were subject to new reporting and registration requirements. Credit rating agencies were subject to greater disclosure and legal liability provisions, and references to credit ratings were required to be removed from statute and regulation. Executive compensation and securitization reforms attempted to reduce incentives to take excessive risks. Securitizers were subject to risk retention requirements, popularly called "skin in the game." It made changes to bank regulation to make bank failures less likely in the future, including prohibitions on certain forms of risky trading (known as the "Volcker Rule"). It created new mortgage standards in response to practices that caused problems in the foreclosure crisis. This report reviews issues related to financial regulation and provides brief descriptions of major provisions of the Dodd-Frank Act, along with links to CRS products going in to greater depth on specific issues. It does not attempt to track the legislative debate in the 115th Congress.
