The Federal Reserve (Fed) defines monetary policy as the actions it undertakes to influence the availability and cost of money and credit to help promote its congressionally mandated goals, achieving a stable price level and maximum sustainable economic growth. Since the expectations of market participants play an important role in determining prices and growth, monetary policy can also be defined to include the directives, policies, statements, and actions of the Fed that influence how the future is perceived. In addition, the Fed acts as a "lender of last resort" to the nation's financial system, meaning that it ensures its sustainability, solvency, and integrity. This role has become of great importance with the onset of the financial crisis in the summer of 2007. This book explores the background, current policy and conditions of the U.S. Monetary Policy and Federal Reserve.
