"In theory, there is no difference between theory and practice. In practice, there is."
Yogi Berra
In its Dec. 12 announcement, the Federal Reserve directly connected its current policy of keeping interest rates unnaturally -- and in my opinion, punishingly -- low, and the unemployment rate, announcing that it will keep rates at essentially zero until unemployment drops below 6.5 percent.
Economic theory suggests that low interest rates stimulate job growth. Low rates encourage consumer borrowing and business investment, which drives economic growth, which stimulates hiring, which lowers unemployment. In theory.
As the great sage of baseball notes, theory and practice are two separate things. The Fed's policy isn't working, and it's doing more harm than good, producing more losers than winners.
The losers are the nation's savers and any business or government entity responsible for funding long-term obligations. Anyone trying to prudently save for retirement is challenged. This is particularly problematic for baby boomers, many of whom are gravitating to more conservative investments such as fixed-income investments.
With inflation running about 2 percent a year, it has become increasingly difficult, if not impossible, to keep up with inflation using this strategy without taking on significantly more risk. This seems particularly unfair to me, since generally these folks are not the ones who borrowed irresponsibly, contributing to the financial crisis in the first place.
If there is any consolation to the unnaturally low rates, it is that households that prudently managed their credit ratings and did not over-borrow against their homes are now able to refinance their mortgages at extraordinarily low rates, often substantially reducing their monthly mortgage expense.
