To imagine quantitative easing (QE), just think of Federal Reserve employees in front of a computer. In the beginning, they had to select and buy securities worth $1.25 trillion. At $1,249,999,999,999.39, they wound up 61 cents short of their goal.
Because of QE1, QE2, and QE3, financial institutions received more than $4 trillion:
But did it make a difference?
During the 2008 recession, traditional monetary policy tools were not working. One problem was that most banks bought U.S. treasuries instead of making loans. To grow the economy, the Fed had to get banks lending again..
Stated very simply, QE gives banks money and then encourages them to lend it:
- First, the Fed flooded the financial system with money by buying the risky securities banks had purchased before the recession started. Those mortgage-backed securities were also called toxic assets.
- Then, the Fed had to be sure that banks did not buy Treasuries with the money they received. So they reduced the Treasuries’ yield by buying more of them too.
The authors of a new study from the New York Fed believe that QE had a positive economic impact. They formed their conclusions by comparing regional economic conditions. In areas where QE purchases replaced mortgage-backed securities, the uptick was more than where they had not. There were more loans and more mortgages were refinanced. As a result, local residents felt wealthier and spent more.
In other words, QE did what it was supposed to do.
Our Bottom Line: Conventional Monetary Policy
- It is least likely but possible that the Fed will change the banking system’s reserve ratios.
- More typically, the Fed can raise or lower the discount rate and thereby affect a bank’s cost of borrowing money from it.
- Most regularly, the Fed targets the interbank lending rate by buying and selling government securities through open market operations.
So, when none of the three conventional alternatives worked, they launched QE.
My sources and more: Always readable, the NY Fed’s Liberty Street blog had the QE analysis while Ed Yardeni presented the chronology. Then, NPR’s Planet Money visited the Fed when it implemented QE. And, for even more, I recommend this NY Times summary and a marketplace.org Whiteboard video that has the perfect QE explanation.
