In an op-ed in The Washington Post, Fed Chair Ben Bernanke explains his latest move:
Here’s the key part:
Unfortunately, the job market remains quite weak; the national unemployment rate is nearly 10 per cent, a large number of people can find only part-time work, and a substantial fraction of the unemployed have been out of work six months or longer. The heavy costs of unemployment include intense strains on family finances, more foreclosures and the loss of job skills.
Today, most measures of underlying inflation are running somewhat below 2 per cent, or a bit lower than the rate most Fed policymakers see as being most consistent with healthy economic growth in the long run. Although low inflation is generally good, inflation that is too low can pose risks to the economy – especially when the economy is struggling. In the most extreme case, very low inflation can morph into deflation (falling prices and wages), which can contribute to long periods of economic stagnation.
Even absent such risks, low and falling inflation indicate that the economy has considerable spare capacity, implying that there is scope for monetary policy to support further gains in employment without risking economic overheating. The FOMC decided this week that, with unemployment high and inflation very low, further support to the economy is needed. With short-term interest rates already about as low as they can go, the FOMC agreed to deliver that support by purchasing additional longer-term securities, as it did in 2008 and 2009. The FOMC intends to buy an additional $600 billion of longer-term Treasury securities by mid-2011 and will continue to reinvest repayments of principal on its holdings of securities, as it has been doing since August.
As for assessing the program:
This approach eased financial conditions in the past and, so far, looks to be effective again. Stock prices rose and long-term interest rates fell when investors began to anticipate the most recent action. Easier financial conditions will promote economic growth. For example, lower mortgage rates will make housing more affordable and allow more homeowners to refinance. Lower corporate bond rates will encourage investment. And higher stock prices will boost consumer wealth and help increase confidence, which can also spur spending. Increased spending will lead to higher incomes and profits that, in a virtuous circle, will further support economic expansion.
While they have been used successfully in the United States and elsewhere, purchases of longer-term securities are a less familiar monetary policy tool than cutting short-term interest rates. That is one reason the FOMC has been cautious, balancing the costs and benefits before acting. We will review the purchase program regularly to ensure it is working as intended and to assess whether adjustments are needed as economic conditions change.
