Costs of the Fed, Part 2

In the previous post I discussed how lowering interest rates adversely affects people with money in savings accounts. I argued that because savers receive less interest income, they have less money to spend, which dampens economic activity. In this post I will return to the idea that lowering interest rates can cause consumers to spend less money. But whereas Part 1 discussed how a decline in interest income affects people who have already saved money, this post will examine how the Fed's actions can change the behavior of people who are trying to build savings.

Economists often teach that lowering interest rates causes consumers to save less and spend more. "Low interest rates provide a powerful incentive to spend rather than save," declares one Federal Reserve publication. The logic underlying this assumption is straightforward: When rates are lower, saving is less attractive and spending is more attractive, so people save less and spend more. If true, this makes Fed policy more effective because when people spend more, the economy grows. And growth is exactly what the Fed is hoping to achieve by lowering rates.

But there is another way to look at this. Consider a family that is trying to save $25,000 for college and $250,000 for retirement over the next 20 years. If interest rates are 5% for the next 2 decades, the family will need to save about $547 per month. With rates at 2%, they will need to set aside $762. The lower the rate, the more they have to save. This runs counter to some of the dominant thinking about lowering interest rates.

Lowering rates probably does cause some people to save less, especially people who are deciding what to do with money that they do not need for basic expenses (ie., rich people). The thinking might go something like: "Should I buy a new Mercedes now or earn 5% for a year and then get the Mercedes with a moon roof? I'll earn the 5%. But if rates are only 2%, it's time to shop." Makes sense. Of course, that is not how a household of limited means and specific financial goals should go about making decisions. For the vast majority of Americans, lowering rates should cause savings rates to increase and spending to decline.

None of this is to say that there are not other factors that might cause people to save less when the Federal Open Market Committee lowers interest rates. When the stock market goes up, people feel richer. I do not dispute that, though I do intend to address some problems with the phenomenon in a later post. Additionally, if the economy does better, confidence rises, prompting people to spend more. However, Federal Reserve publications and Ben Bernanke's many recent statements would have us believe that monetary easing (lowering rates and printing money) categorically stimulates economic growth as long as inflation is not a problem. There has been very little discussion by Fed officials of the ways in which Fed policy causes some pockets of the economy to contract. A cost-benefit analysis that models who wins and who loses - and how much they win or lose - is sorely needed.

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.

End The Fed?

I just finished reading Senator Ron Paul's "End The Fed." The book outlines the controversial libertarian's reasoning for wanting to shut down the Federal Reserve. Headed by Ben Bernanke, the Federal Reserve has the power to print U.S. dollars - a power the Fed has been using frequently in recent years. Paul argues that this is a form of tyranny enabling the Fed to covertly tax Americans by devaluing their money. And he believes the Fed uses this power to serve the interests of "the banking cartel" and "the most powerful politicians in Washington."

Perhaps Paul is correct that our central bank's manipulation of the money supply, interest rates, and asset prices does not benefit our economy. And perhaps it is true that the Fed enables a few powerful interests to enrich themselves at public expense. I increasingly suspect that he is onto something. But surely lowering interest rates does benefit some parts of the economy and can lead to growth and job creation in some industries, even if only temporarily. Paul would have us believe that the costs of monetary stimulus are higher than the benefits. Unfortunately, "End the Fed" provides little concrete evidence to support these conclusions.

Paul's best argument against the Fed is that it has a dangerous power in its ability to print money with little oversight by Congress. This does seem inconsistent with democratic values. But this is not new information. Americans appear willing to grant the Fed this power if the result is a stronger and more stable economy. Supporters of the Fed contend that the ability to change interest rates, help the financial system, and control the money supply is of great value to all Americans. After reading "End The Fed," I am not better able to rebut such assertions.

Paul deserves much credit for raising questions about the merits of our monetary system. His book has at the very least prompted more Americans to begin questioning the status quo. However, he fails to offer sufficient evidence to convince us that the Fed does more harm than good. We need to see some data showing that any gains are offset by economic losses elsewhere. The book does not even provide a theoretical explanation as to why any investment and spending spurred by monetary expansion is bad for the economy. More analysis is needed.
