As many predicted, the Federal Reserve has agreed on another round of quantitative easing — essentially printing "new" money — in a bid to jump start the economy (read more on quantitative easing from The Week). The Fed announced yesterday it would buy up $600 billion of long-term government bonds, or Treasuries, by the middle of 2011 in hopes of driving down rates on mortgages and other debt and spurring investment. That comes on top of an expected $300 billion in buying from earlier programs. Will this massive cash injection be enough to revitalize the economy? (Watch a CNBC discussion about the announcement)

The evidence suggests it won't help much: The Fed surprised everyone by pumping $1 trillion into the economy in March last year, notes Rick Newman at U.S. News & World Report, and while it steadied the stock market, it didn't speed up GDP growth. This round "will probably have far less impact" — mainly because the market was expecting it for months and has already priced it into expectations.
"Why the Fed's quantitative easing is overblown this time"

$600 billion a lot of money — but still too little: Call this quantitive easing "lite," says John Kemp at Reuters. "After all the thunderous commentary" for and against pumping more cash into the economy, the Fed has "labored mightily and brought forth a mouse." Only "shock and awe" could have jolted the market into action. This may "shave more than a few basis points" off interest rates, but the overall effects "will probably be marginal."

It's already worked: "I'm struck by the extent of the scepticism regarding this action," says The Economist. Sure, the "impact of easing" had already hit the markets. But "that impact is impressive." Equity markets are up and the dollar is down — which will help "domestic firms thinking about hiring and investing." It may not solve our unemployment rate, but "it's not clear that any Fed action" could do that.
