VIENNA – The United States Federal Reserve is the world’s most powerful bank, and its most powerful component is the Federal Open Market Committee (FOMC), the twelve men and women who meet eight times a year to determine – essentially by setting interest rates – the monetary policy of the world’s largest economy. The last time the Fed raised interest rates was in 2006, before the growth-sapping impact of the global financial crisis persuaded it and other central banks to lower rates effectively to zero and to employ so-called quantitative easing (QE) to pump money into advanced economies.
