Central bank communication

Talking about Tapering

In May, we argued that the FOMC needed to communicate its contingency plans for what they would do should the recent inflation pickup prove more stubborn than its members expect. Such transparency makes it more likely that financial markets will respond to incoming data rather than to policymakers’ actions. By clearly laying out their reaction function, central bankers can avoid disruptions like market taper tantrums.

In June, the FOMC began to remove the self-imposed communication shackles designed to encourage “lower for longer” interest rate expectations and address inflation risks more openly. Indeed, as the above citation from Chairman Powell indicates, at their June meeting, policymakers began to lay the groundwork for scaling back their large-scale asset purchases (LSAPs).

In this post, we start by highlighting how recent Fed communication (which reveals appropriate humility about inflation projections) has helped avoid a market tantrum so far. Along the way, we discuss the various means that FOMC participants have used to express their changing views about the timing of interest rate increases (“liftoff”), even as they make clear that tapering their asset purchases will come first….

Inflation: Don't Worry, Be Prepared

Everyone seems to be worried about inflation (see here and here). People also are concerned that the rising media salience of inflation could raise inflation expectations, leading to a sustained rise in inflation itself.

April price readings certainly boosted these worries: the conventional measure of core inflation—the CPI excluding food and energy—rose by nearly 3% from a year ago, the biggest gain since 1995. Fed Vice Chair Richard Clarida summed up the nearly universal reaction when he said: “I was surprised. This number was well above what I and outside forecasters expected.”

The experience of the high-inflation 1970s makes people prone to worrying about such things. Our reaction is different. After all, worry alone is not going to prevent a sustained pickup of inflation. Only credible anti-inflationary monetary policy can do that. To ensure that inflation expectations remain low, it is up to the central bank to make sure everyone understands how policy will respond if the latest elevated inflation readings prove to be more than temporary. As we have written before, the key is effective communications, not premature action….

Stopping central banks from being prisoners of financial markets

Central banks are on the front lines in the fight to limit the impact of the pandemic. They are supporting virtually every aspect of the economy and the financial system. Combined with the massive fiscal support, these policies restored market stability, safeguarded financial institutions, and reduced suffering. Count us among those who firmly believe that everyone would be in worse shape had central banks and fiscal authorities not coordinated this aid as they did.

But, by providing such a broad backstop, the reliance of financial markets on that support can itself become a source of instability. This raises a set of very important and pressing questions: Have central banks’ actions over the past year made financial markets their masters? Can policymakers now be counted on to suppress financial volatility wherever it arises?

We surely hope not, but we see this as a legitimate concern. Fortunately, we also see a solution. Central bankers should strive to duplicate the success of their framework for interest rate policy. That is, they should be clear and transparent about their reaction function for all their policy tools. Knowing how policy will react, markets will respond directly to news regarding economic conditions, and less to policymakers’ commentary. Of course, central bankers cannot ignore shocks that threaten economic and price stability. But cushioning the economy against large financial disturbances does not mean minimizing market volatility….

Communicating Monetary Policy Uncertainty

When it comes to forecasting, we usually cite famous Yankee catcher and baseball philosopher Yogi Berra, who reputedly said: “It's tough to make predictions, especially about the future.”

For central bankers, this is more than just a minor headache. Given the lags between policy actions and their effects, forecasting is unavoidable. That puts uncertainty about the economic outlook at the heart of the policymakers’ daily job. Indeed, no one knows the future path of the economy or interest rates—not even those making the decisions.

Communicating this inevitable monetary policy uncertainty is difficult, but essential. In the United States, the Federal Open Market Committee (FOMC) uses a variety of means for this purpose. In two earlier posts, we discussed the evolution of FOMC communications and the usefulness of the quarterly survey of economic projections (SEP). Here, we examine a key aspect of FOMC communications that receives insufficient attention: the explicit publication of policymakers’ range of uncertainty about the future path for the policy rate. Buried near the end of the FOMC minutes, published three weeks after the SEP release, this information is consumed only by die-hard devotees….

Dot-ology: What can we learn from the dot plot?

The primary objective of monetary policy is to keep inflation and unemployment low and stable. To be effective, central bankers must address shocks to inflation and unemployment, while ensuring that what they say and do is not a source of volatility. One way to make a commitment to stability credible is for policymakers to broadcast their likely responses to shocks—their reaction function. Such transparency escalates the cost of reneging, helping to anchor expectations about the future that influence current behavior (see our primer on time consistency). And, because they can anticipate how policy will respond to changes in economic and financial conditions, it improves everyone’s economic and financial decisions.

With such a stability-oriented policy strategy, the policy path will depend on what happens in a changing world. Only under specific circumstances―such as when the short-term interest rate is at or near its effective lower bound―will policymakers be inclined to commit to a specific future policy path.

Recently, we wrote about the remarkable evolution of Federal Reserve monetary policy communication over the past quarter century. Today, the Federal Open Market Committee (FOMC) publishes statements, minutes, and quarterly forecasts for growth, inflation, unemployment, and interest rates. In this post we take up a narrow question: What can we learn from the information published in the FOMC’s quarterly Summary of Economic Projections (SEP)?

Our answer is: quite a bit. The data allow us to estimate not only an FOMC reaction function, but also a short-run projection of the equilibrium real rate of interest (r*)―one that is consistent with projected economic conditions over a two- to three-year horizon—in addition to the long-run r* that is implicit in each SEP. While there is almost surely room to improve on the SEP, we conclude, as a friend and expert Fed watcher once suggested, “Don’t ditch the dots” ….

Navigating in Cloudy Skies

Stargazers hate clouds. Even modest levels of humidity and wind make it hard to “see” the wonders of the night sky. Very few places on our planet have consistently clear, dark skies.

Central bankers face a similar, albeit earthly, challenge. Even the simplest economic models require estimation of unobservable factors; something that generates considerable uncertainty. As Vice Chairman Clarida recently explained, the Fed depends on new data not only to assess the current state of the U.S. economy, but also to pin down the factors that drive a wide range of models that guide policymakers’ decisions.

In this post, we highlight how the Federal Open Market Committee’s (FOMC’s) views of two of those “starry” guides—the natural rates of interest (r*) and unemployment (u*)—have evolved in recent years. Like sailors under a cloudy sky, central bankers may need to shift course when the clouds part, revealing that they incorrectly estimated these economic stars. The uncertainty resulting from unavoidable imprecision not only affects policy setting, but also complicates policymakers’ communication, which is one of the keys to making policy effective….

Connect the Dots

How and what should the Federal Open Market Committee (FOMC) communicate to make monetary policy most effective? That is the question addressed by this year’s U.S. Monetary Policy Forum report (Language After Liftoff: Fed Communication Away from the Zero Lower Bound).

Over the past two decades, the FOMC has made enormous strides in promoting transparency. In sharp contrast to most of its previous history, the Fed now emphasizes that transparency enhances the effectiveness of monetary policy.

Yet, central bank communication is a work in progress. And, as the new USMPF report argues, there remains scope for improvement. In our view, the simplest and most useful change that the authors recommend, and that the Fed could implement—immediately and without cost—is to “connect the dots:” that is, to link (while maintaining anonymity) the published interest rate forecasts of each FOMC participant that appear in the quarterly “dot plot” (found in the Summary of Economic Projections, or SEP) to that same person’s projections of inflation, unemployment, and economic growth.
