The federal funds rate, or the interest rate that U.S. banks charge each other for overnight loans, is the benchmark rate for many short-term and long-term interest rates in the United States. A reduction in the federal funds rate, often times (though not always), decreases the interest rate on credit cards, automobile loans, and mortgages. Lower interest rates encourage consumers to spend and businesses to build new offices and purchase computers, machinery, and software. A boost in consumption (e.g. buying new clothes) and investment (e.g. building new offices) (with the added benefit of lowering the value of the dollar and thus boosting U.S. exports) spending are exactly what the economy needs when it is slipping into a recession caused by sudden drops in overall spending. Though the U.S. economy is NOT officially in a recession, the Federal Reserve forecasts “slowed growth” and would like to cut rates just-in-case.
The previous explanation shows how the Federal Reserve could use monetary policy to minimize the depth and length of a recession. However, what is less well known is the process with which the Federal Reserve is able to manipulate the federal funds rate. Essentially, the Federal Reserve lowers the federal funds rate by expanding the money supply. This is easier said than done.
First and foremost, the Federal Reserve does NOT print new dollar bills. So how is it able to create new money? There are two main forms of money—cash in circulation and checking deposits held in banks. Separate from the money supply are “reserve accounts” that commercial banks are required to have at the Federal Reserve. These reserve accounts hold cash for the commercial banks in case depositors cash-out some of their deposits.
The Federal Reserve can expand the money supply by expanding the amount of deposits held in the U.S. commercial banking system. One way to do so is to purchase U.S. government bonds issued by the U.S. Treasury department. When the Federal Reserve purchases government bonds from commercial banks, it takes bonds out of circulation and electronically credits reserve accounts. U.S. commercial banks armed with more cash reserves will issue new loans which are then deposited back into the banking system. This method effectively increases the dollar amount of checking deposits in the economy, and hence, expands the money supply.
Discussion Questions
1. Suppose U.S. commercial banks are highly reluctant to issue new loans even if they are armed with more reserves. How would this impact the Federal Reserve’s ability to expand the money supply and lower the federal funds rate?
2. Republican presidential candidate, Ron Paul, believes that the Federal Reserve “debases and depreciates” the currency through its manipulation of the money supply. In fact, he wants to abolish the Federal Reserve altogether. Using the definition of the money supply and the relationship between interest rates and unemployment, how could the money supply be “pro-cyclical” without the Federal Reserve?
What’s a fiscal authority to do?
As Greg Mankiw recently pointed out and Wall Street Journal reporter David Wessel was quick to observe nearly a month ago, the actual federal funds rate has been trading below the Fed’s target federal funds rate of 5.25%. The federal funds rate is the rate at which banks borrow from one another overnight, and it is the key benchmark interest rate for monetary policy. The Fed targets a relatively low, or loose, fed funds rate in order to encourage borrowing, speed up economic growth, and avoid recession. The Fed targets a neutral rate when it wants neither slower nor faster growth than the economy is currently experiencing. The Fed targets a relatively high, or tight, rate when it wants to discourage some borrowing, slow the pace of economic growth, and ensure price stability (low and stable inflation).
According to Mankiw, the actual fed funds rate averaged 5.02% during August—23 basis points lower than the target—while in the preceding 13 months, the Fed had never allowed the actual rate to deviate from the target by more than 1 basis point. Although we can’t be sure until the next Federal Open Market Committee (FOMC) meeting on Tuesday, September 18, the behavior of the actual rate in August seems to suggest that the Fed will cut the target federal funds rate to at least 5.0%. A rate cut would mean that the Fed is backing away from a tighter policy stance associated with reducing inflation, and moving instead toward a more neutral monetary policy that will allow it to wait and see how the recent subprime and housing-market turmoil plays out in the broader economy.
The prospect of a rate cut raises the issue of moral hazard. Some critics feel that any loosening by the Fed will bail out borrowers who have taken on risky subprime mortgages and investors who have purchased the assets backed by such mortgages. By cutting rates, the Fed may encourage borrowers, lenders, and investors to make similar gambles in the future on the assumption that the Fed will intervene if things turn sour. Tyler Cowen’s latest New York Times column argues that while the Fed should not go out of its way to help poor decision makers, the Fed’s mandate—price stability and full employment—should not be sacrificed for fear of instigating moral hazard.
Discussion Questions
1. If banks become increasingly reluctant to lend to one another and to individual borrowers, what will happen to the types of consumption and investment expenditures that are typically financed by borrowing?
2. If borrowing difficulties persist for an extended period of time, what would you expect to happen to housing prices? What about economic growth? How should the Fed respond to this type of credit crunch?
3. Consider the borrowers, lenders, and investors who made poor decisions in the subprime market. Will some of them benefit from an FOMC decision to cut rates? Can the Fed prevent all moral hazard associated with monetary policy decisions? Can Fed policy provide total relief to the borrowers, lenders, and investors who made poor decisions in the subprime markets?
But what, if anything, can the fiscal authority—Congress and the President—do to assist the economy? According to Fed chair Ben Bernanke, “Fiscal action could be helpful in principle, as fiscal and monetary stimulus together may provide broader support for the economy than monetary actions alone.” (Read this New York Times article for more.) However, Bernanke is hedging a bit here. By saying that tax cuts or spending increases “could be helpful in principle,” he implicitly acknowledges that such measures may be ineffective, or even harmful, in practice. The process of agreeing on and passing legislation limits the usefulness of fiscal policy for stabilizing mild fluctuations in economic output. By the time our representatives haggle over and pass legislation, the downturn may be over or the resulting policy may reflect political rather than economic considerations. For this reason and others, recent commentaries by Greg Mankiw and Robert J. Samuelson argue that we should leave the Fed to address mild ups and downs in the business cycle, reserving fiscal policy for deep or prolonged recessions.
Discussion Questions
1. Limitations of fiscal policy aside, Bernanke seems to understand that politicians seeking a track record to run on will often favor policy action over informed inaction. What advice does he give policymakers who are eager to implement fiscal policy?
2. Three specific types of “lag” may delay the beneficial effects of economic policies. The recognition lag is the time it takes us to figure out we’re in an economic pickle. We often don’t know that we’re in a recession until months after it’s started. The implementation lag is the time it takes policymakers to agree on and implement policies. The impact lag is the time it takes a policy to work its way through the economy and affect economic output and unemployment. For example, an increase in government spending on highway construction will show up as additional output over the entire life of the project, not all at once. How might these lag times differ between monetary and fiscal policy?
3. Plotting economic output over time reveals two basic observations: the smooth upward trend in output growth over the long haul, and the up-and-down wiggle of output in the short term. To paraphrase Aplia’s founder Paul Romer, it’s easy to lose sight of the trend for the wiggle. Policymakers can get so wrapped up in temporary economic tumults that they lose focus on the bigger picture. If we’re headed for recession, odds are that it will be mild by historical standards and the Fed will have plenty of policy ammunition to soften its adverse effects. Meanwhile, small changes in the long-run rate of economic growth have large impacts on future living standards. Given that, what policies would you recommend the action-minded fiscal authority focus on to improve the long-term growth prospects of the U.S. economy?
