Costs of the Fed, Part 1

The U.S. Federal Reserve has created trillions of new dollars in the last few years. This has been controversial. Opponents of this policy usually argue that creating so much money could lead to massive inflation. However, as more and more time passes without any serious bouts of inflation, the Fed increasingly seems to be winning the debate. But what if the Fed is doing other sorts of damage to the economy? What if inflation is not the only metric by which we should judge Federal Reserve policy?

There are many other costs to the Fed's recent radical interventions - costs that deserve a lot more attention. I intend to write a series of posts on this topic, starting today.

Costs of the Fed, Part 1:

One of the most obvious costs of increasing the money supply and decreasing interest rates is that people who save money in interest-bearing accounts earn less money. The elderly and people without significant wealth often suffer the most from low returns on savings accounts and CD's. Because these savers are not able to bear the risks associated with stocks and bonds, they put significant amounts of their savings into safer interest-bearing accounts. When the Fed floods the banking system with money, banks have less need for deposits, deposit rates go down, and depositors receive lower returns. Obviously, this is bad for people with money in interest-bearing accounts.

But there are other consequences as well. If these savers have less money, they will probably spend less, hurting the entire economy.* According to data from the Federal Reserve of Philadelphia, American households' annual interest income has declined by 150 Billion dollars since 2008. That amounts to over a full percentage point of U.S. GDP. This does not mean that lowering interest rates caused GDP to shrink. Reduced rates can help borrowers. Indeed, the same data that shows households earned less interest income also shows that households paid less interest on their debts. Unfortunately, the decrease in interest income was over twice as large as the decrease in interest expenses, so American households were net losers in this regard.

The Fed contends that the benefit to borrowers leads to increased economic activity in aggregate. However, the Fed has not done a good job of proving this. A publication by the Fed's St. Louis branch entitled "Low Interest Rates Have Benefits . . . And Costs" provides a sensible list of some of the benefits and costs of lowering rates. Lacking from this paper is any attempt to quantify the benefits or reach a conclusion about the net effects on the economy. Have lower rates caused borrowers to increase economic activity enough to offset the loss of income suffered by savers? The right answer is probably that it depends on an array of factors including the outlook for business, economic expectations, and household financial health, among other things.

The Fed does not seem to be calibrating its policy to these ever shifting variables. Rather, the Fed seems anchored to the notion that decreasing rates increases economic activity as long as inflation is not a problem. Consider a scenario in which a country had invested too much in housing and households had not saved enough. It is possible that under those circumstances, decreasing savers' income in order to increase investment is the wrong response and will not lead to a stronger economy. If it is indeed true that lowering rates can consistently be relied upon to stimulate the economy, then the Fed ought to better job of proving it.

*Many economists often argue that lowering interest rates causes people to spend more and save less because the return on savings is less attractive. I will address some complications with this theory in the next post.
