The Federal Reserve system was designed, built and operated as an agency that forced its policies on American banks. The banks in turn had the power to push around the real economy. Now the Federal Reserve finds itself in a world where banks don't matter as much. Markets set interest rates, markets determine liquidity and markets help or hinder the plans of businessmen. Markets are unpredictable, international and, worst of all, they have their own information systems that do not follow the rules of banking or bank supervision. In response, the Federal Reseve has reinvented itself in a way not yet understood even by sophisticated investors.
