The Federal Reserve is famous for being tight-lipped about its potential monetary policy moves. In desperate attempts to predict what Fed policy-makers are thinking, market-watchers occasionally resort to rather odd measures. For example, on mornings when the Federal Open Market Committee (FOMC) meets to discuss the economy and make decisions regarding monetary policy, the media often focus on the image of Fed Chairman Alan Greenspan carrying his briefcase into the front door of the Federal Reserve Board building. In fact, www.CNNfn.com updates its "Eyes on the Fed" section with commentary and pictures of the chairman's briefcase on the mornings of FOMC meetings at www.cnnfn.com/news/specials/eyes_on_fed. If the briefcase is bulging, so the speculation goes, it is full of evidence that has been gathered by Greenspan to persuade other members of the FOMC to vote for a higher interest rate target. If the briefcase is thin, so the theory goes, then markets can relax because no change is likely.
Unfortunately for the Fed watchers, the size of the briefcase is not always a good predictor of the Fed's actions. A look at the May 2000 FOMC meeting highlights this point. Despite the fact that Greenspan's briefcase was reportedly at its thinnest in years that morning, the FOMC raised its interest rate target by half a percentage point, its largest increase in five years. Therefore, it's not the size of the briefcase that matters, but the type and quality of information found inside.
Most likely, the information in the briefcase is data released by government statistical agencies—information about labor markets, prices, industrial production, capacity utilization, business inventories, factory orders and shipments, etc. Most, if not all, of this information is in the public domain. The question is, what do the data tell the Fed about the economy that will cause the FOMC members to make a decision to either tighten the money supply, loosen the money supply or leave it the same?
Before trying to predict the Fed's actions, one must first understand the Fed's objective of promoting maximum sustainable growth in our economy. Because monetary policy is the primary determinant of inflation in the long run, the Fed achieves this objective by supplying just enough money and credit so that the economy will operate at its potential without igniting inflation. However, at the time the Fed takes a policy action, it does not know, and can only do its best to predict, what effects its decisions will have on the future. The information inside the Fed chairman's briefcase is used to make these predictions.
In principle, knowing the forecasts and the latest information about the economy—that is, the contents of the briefcase—should help one predict what decision the FOMC will make about monetary policy. In practice, Fed forecasts are not available to the public on a timely basis. Private business economic forecasts, however, closely mirror Fed forecasts and can help one to predict FOMC decisions. People use economic forecasts and the deviations of actual inflation and growth from the forecasts as tea leaves for reading the Fed's objectives. For example, let's assume the Fed's forecast for inflation is 2.5 percent for the year, and data on prices indicate that inflation is running 3.5 percent for this quarter. In that event, people will expect the Fed to tighten the money supply so that spending will decrease. This should eventually cause demand for goods and services—and thus, prices—to decline. Sometimes monetary policy is relatively straightforward. For example, if output and inflation are both coming in above expectations, then FOMC members and the marketplace are likely to agree that the Fed must tighten policy. Similarly, if inflation and GDP growth are both coming in below expectations, then the market should not be surprised to see the Fed ease its policy stance.
The more difficult cases occur when GDP growth and inflation surprise us in opposite directions. This means that if growth is weaker than expected and inflation is higher, there will be a debate between those who want to fight inflation and those who want to stimulate output. Conversely, with surprisingly high growth and unexpectedly low inflation, some will want to tighten the money supply because they fear that the rapid growth is not sustainable without inflation. The concern is that failing to tighten policy now will lead to higher inflation down the road. Others, though, will note that inflation is below expectations, so why not wait for more information before changing the policy stance? Such are the policymaking challenges presented by the contents of the chairman's briefcase.
