US Central Bank to Pump $600 Billion into Economy VOA News 03 November 2010 Unemployed people use computers and telephones to search for jobs and seek out unemployment insurance benefits at the Nevada JobConnect Career Center in Las Vegas (Sep 2010 file photo) Photo: AP Unemployed people use computers and telephones to search for jobs and seek out unemployment insurance benefits at the Nevada JobConnect Career Center in Las Vegas (Sep 2010 file photo) The U.S. central bank says it will pump another $600 billion into the American marketplace in hopes of boosting the nation's sluggish economy. The Federal Reserve said Wednesday it will buy about $75 billion of government securities each month from now through June 2011. It called this an effort to cut the nation's high unemployment rate - now nearly one of every 10 workers - and to keep interest rates low for an "extended period." In addition, the central bank said it will reinvest proceeds of mortgage payments it is receiving from earlier purchases of securities. Along with the new stimulus, that is expected to push the total economic boost to somewhere between $850 billion and $900 billion. The policy, called "quantitative easing," was advocated by Federal Reserve chairman Ben Bernanke. Its goal is to put downward pressure on long-term interest rates paid by businesses and consumers, and to prime the U.S. economy for sustained growth. Such an infusion of money into the economy could make it easier for consumers to increase spending, and for businesses to hire more workers. But critics say the plan might not have much effect on the economy and might generate another economic ill, higher inflation. The Federal Reserve's action came a day after opposition Republicans reclaimed control of the U.S. House of Representatives from majority Democrats, and gained ground in the Senate. With President Barack Obama, a Democrat, now sharing political power in Washington, some economists are predicting further gridlock. The two parties often are at odds on government spending and economic priorities. In the aftermath of the election, Mr. Obama and victorious Republican leaders pledged to work together to try to cure the nation's economic plight. Even so, the central bank's position on boosting the world's biggest economy took on added importance. Interest rates paid by businesses and consumers when they borrow money to buy homes already are at very low rates. But such low interest rates have not spurred significant economic growth in the U.S., even though the recession officially has been over since June 2009.  In the July-to-September 2010 period, the U.S. economy grew at a 2 percent annual rate, slightly more than the 1.7 percent expansion of the previous three months. But economists think 3 percent growth is needed over a period of time before businesses will start hiring significant numbers of new workers. In 2009, in the midst of the recession, the Federal Reserve bought $1.7 trillion in mortgage and treasury bonds. By purchasing the new securities gradually, the central bank said it can review the effect on the economy before deciding how to proceed. .
