Discuss the method of quantitative easing used by the Federal Reserve during the recession of 2008, including any criticisms of this action

The method of quantitative easing used by the Federal Reserve involved making discount rate loans broadly available to many financial firms like those that buy and sell financial securities or even insurance companies, not just to banks.
The quantitative easing policies adopted by the Federal Reserve (and by other central banks around the world) are usually thought of as temporary emergency measures. But, if these steps are indeed to be temporary, then the Federal Reserve will need to stop making these additional loans and sell off the financial securities it has accumulated—and the process of quantitative easing may prove more difficult to reverse than it is to enact.
