To maintain that level, the Fed bought $30 billion in two- to ten-year Treasury notes every month. In November 2010, the Fed announced a second round of quantitative easing, buying $600 billion of Treasury securities by the end of the second quarter of 2011. The expression "QE2" became a ubiquitous nickname in 2010, used to refer to this second round of quantitative easing by US central banks. Retrospectively, the round of quantitative easing preceding QE2 was called "QE1". A third round of quantitative easing, "QE3", was announced on 13 September 2012. In an 11–1 vote, the Federal Reserve decided to launch a new $40 billion per month, open-ended bond purchasing program of agency mortgage-backed securities. Additionally, the Federal Open Market Committee (FOMC) announced that it would likely maintain the federal funds rate near zero "at least through 2015". According to NASDAQ.com, this is effectively a stimulus program that allows the Federal Reserve to relieve $40 billion per month of commercial housing market debt risk. Because of its open-ended nature, QE3 has earned the popular nickname of "QE-Infinity". On 12 December 2012, the FOMC announced an increase in the amount of open-ended purchases from $40 billion to $85 billion per month. On 19 June 2013, Ben Bernanke announced a "tapering" of some of the Fed's QE policies contingent upon continued positive economic data. Specifically, he said that the Fed could scale back its bond purchases from $85 billion to $65 billion a month during the upcoming September 2013 policy meeting. He also suggested that the bond-buying program could wrap up by mid-2014. While Bernanke did not announce an interest rate hike, he suggested that if inflation followed a 2% target rate and unemployment decreased to 6.5%, the Fed would likely start raising rates. The stock markets dropped by approximately 4.3% over the three trading days following Bernanke's announcement, with the Dow Jones dropping 659 points between 19 and 24 June, closing at 14,660 at the end of the day on 24 June. On 18 September 2013, the Fed decided to hold off on scaling back its bond-buying program, and announced in December 2013 that it would begin to taper its purchases in January 2014. Purchases were halted on 29 October 2014 after accumulating $4.5 trillion in assets. During its QE programme, the Bank of England bought gilts from financial institutions, along with a smaller amount of relatively high-quality debt issued by private companies.
