Part 3: Summary of Economic Projections

Monetary Policy Report submitted to the Congress on February 23, 2018, pursuant to section 2B of the Federal Reserve Act

The following material appeared as an addendum to the minutes of the December 12-13, 2017, meeting of the Federal Open Market Committee.

In conjunction with the Federal Open Market Committee (FOMC) meeting held on December 12-13, 2017, meeting participants submitted their projections of the most likely outcomes for real gross domestic product (GDP) growth, the unemployment rate, and inflation for each year from 2017 to 2020 and over the longer run.13 Each participant's projection was based on information available at the time of the meeting, together with his or her assessment of appropriate monetary policy--including a path for the federal funds rate and its longer-run value--and assumptions about other factors likely to affect economic outcomes. The longer-run projections represent each participant's assessment of the value to which each variable would be expected to converge, over time, under appropriate monetary policy and in the absence of further shocks to the economy.14 "Appropriate monetary policy" is defined as the future path of policy that each participant deems most likely to foster outcomes for economic activity and inflation that best satisfy his or her individual interpretation of the statutory mandate to promote maximum employment and price stability.

All participants who submitted longer-run projections expected that, under appropriate monetary policy, growth in real GDP in 2018 would be somewhat stronger than their individual estimates of its longer-run rate. All participants projected that real GDP growth would moderate in 2019, and nearly all predicted that it would ease further in 2020; a solid majority of participants thought that growth in real GDP would be at or close to their individual estimates of the economy's longer-run growth rate by 2020. All participants who submitted longer-run projections expected that the unemployment rate would run below their estimates of its longer-run normal level through 2020. Participants generally projected that inflation, as measured by the four-quarter percentage change in the price index for personal consumption expenditures (PCE), would step up toward the Committee's 2 percent objective in 2018 and be at or close to that objective by 2019. Most participants indicated that prospective changes in federal tax policy were a factor that led them to boost their projections of real GDP growth over the next couple of years; some participants, however, noted that they had already incorporated at least some effects of future tax cuts in their September projections. Several also noted the possibility that changes to tax policy could raise the level of potential GDP in the longer run.15 Table 1 and figure 1 provide summary statistics for the projections.

Note: Projections of change in real gross domestic product (GDP) and projections for both measures of inflation are percent changes from the fourth quarter of the previous year to the fourth quarter of the year indicated. PCE inflation and core PCE inflation are the percentage rates of change in, respectively, the price index for personal consumption expenditures (PCE) and the price index for PCE excluding food and energy. Projections for the unemployment rate are for the average civilian unemployment rate in the fourth quarter of the year indicated. Each participant's projections are based on his or her assessment of appropriate monetary policy. Longer-run projections represent each participant's assessment of the rate to which each variable would be expected to converge under appropriate monetary policy and in the absence of further shocks to the economy. The projections for the federal funds rate are the value of the midpoint of the projected appropriate target range for the federal funds rate or the projected appropriate target level for the federal funds rate at the end of the specified calendar year or over the longer run. The September projections were made in conjunction with the meeting of the Federal Open Market Committee on September 19-20, 2017. One participant did not submit longer-run projections for the change in real GDP, the unemployment rate, or the federal funds rate in conjunction with the September 19-20, 2017, meeting, and one participant did not submit such projections in conjunction with the December 12-13, 2017, meeting.

As shown in figure 2, participants generally expected that the evolution of the economy relative to their objectives of maximum employment and 2 percent inflation would likely warrant further gradual increases in the federal funds rate. Compared with the projections they submitted in September, some participants raised their federal funds rate projections for 2018 and 2019, while several others lowered their projections, leaving the median projection for the federal funds rate in those years unchanged; the median projection for 2020 was slightly higher, and the median projection for the longer-run normal level of the federal funds rate was unchanged. Nearly all participants saw it as likely to be appropriate for the federal funds rate to rise above their estimates of its longer-run normal level at some point during the forecast period. Participants generally noted several sources of uncertainty about the future course of the federal funds rate, including the details of potential changes in tax policy, how those changes would affect the economy, and the range of factors influencing inflation over the medium term.

In general, participants viewed the uncertainty attached to their economic projections as broadly similar to the average of the past 20 years, and all participants saw the uncertainty associated with their projections for real GDP growth, the unemployment rate, and inflation as essentially unchanged from September. As in September, most participants judged the risks around their projections for economic growth, the unemployment rate, and inflation as broadly balanced.

The Outlook for Economic Activity

The median of participants' projections for the growth rate of real GDP for 2018, conditional on their individual assessments of appropriate monetary policy, was 2.5 percent, the same as for 2017. The median projections for GDP growth in 2019 and 2020 were slightly lower, at 2.1 and 2.0 percent, respectively. Compared with the Summary of Economic Projections (SEP) from September, the median of the projections for real GDP growth for 2018 was notably higher, while the medians for real GDP growth for 2019 and 2020 were modestly higher. The median of projections for the longer-run normal rate of real GDP growth remained at 1.8 percent. Most participants pointed to changes in tax policy as likely to provide some boost to real GDP growth over the forecast period; in September, fewer than half of the participants incorporated prospective tax policy changes in their projections. Several participants indicated that they had marked up their estimates of the magnitude of tax cuts, relative to their assumptions in September.

The medians of projections for the unemployment rate in the fourth quarter of both 2018 and 2019 were 3.9 percent, 0.2 percentage point below the medians from September and about 3/4 percentage point below the median assessment of its longer-run normal level. The median projection for the unemployment rate ticked up slightly to 4.0 percent in 2020.

Figures 3.A and 3.B show the distributions of participants' projections for real GDP growth and the unemployment rate from 2017 to 2020 and in the longer run. The distribution of individual projections for real GDP growth for 2018 shifted up, with more than half of the participants now expecting real GDP growth of 2.5 percent or more and none seeing it below 2.2 percent. The distribution of projected real GDP growth in 2019 and 2020 also shifted up, albeit only slightly. The distribution for the longer-run normal rate of GDP growth was little changed from September. The distributions of individual projections for the unemployment rate in 2018 and 2019 shifted down relative to those in September, broadly consistent with the changes in the distributions for real GDP growth.

The Outlook for Inflation

The median of projections for headline PCE price inflation was 1.9 percent in 2018 and 2 percent in 2019 and 2020, the same as in the September SEP. Most participants anticipated that inflation would continue to run a bit below 2 percent in 2018, and only one participant expected inflation above 2 percent that year. A majority of participants projected that inflation would be equal to the Committee's objective in 2019 and 2020. Several participants projected that inflation would slightly exceed 2 percent in 2019 or 2020. The medians of projections for core PCE price inflation over the 2018-20 period were the same as those for headline inflation.

Figures 3.C and 3.D provide information on the distributions of participants' views about the outlook for inflation. On the whole, the distributions of projections for headline PCE price inflation and core PCE price inflation beyond 2017 were little changed from September.

Appropriate Monetary Policy

Figure 3.E provides the distribution of participants' judgments regarding the appropriate target--or midpoint of the target range--for the federal funds rate at the end of each year from 2017 to 2020 and in the longer run. Overall, the distributions differed in only small ways from those reported in the September SEP. There was a moderate reduction in the dispersion of the distribution for 2020 and for the longer run; some of the lower-end projections for those horizons from the September SEP were revised up in the current projections.

The median projection of the year-end federal funds rate continued to rise gradually over the 2018-20 period. The median projection for the end of 2018 was 2.13 percent; the medians of the projections were 2.69 percent at the end of 2019 and 3.07 percent at the end of 2020. Nearly all participants projected that it would likely be appropriate for the federal funds rate to rise above their individual estimates of the longer-run normal rate at some point over the forecast period. Compared with their projections prepared for the September SEP, a few participants raised their projections for the federal funds rate in the longer run and one lowered it; the median was unchanged at 2.75 percent.

In discussing their projections, many participants once again expressed the view that the appropriate trajectory of the federal funds rate over the next few years would likely involve gradual increases. This view was predicated on several factors, including a judgment that the neutral real interest rate was currently low and would move up only slowly, as well as the balancing of risks associated with, among other things, the possibility that inflation pressures could build if the economy expands well beyond its long-run sustainable level, and the possibility that the forces depressing inflation could prove to be more persistent than currently anticipated. As always, the actual path of the federal funds rate will depend on evolving economic conditions and their implications for the economic outlook.

Uncertainty and Risks

In assessing the path for the federal funds rate that, in their view, is likely to be appropriate, FOMC participants take account of the range of possible economic outcomes, the likelihood of those outcomes, and the potential benefits and costs should they occur. As a reference, table 2 provides a measure of forecast uncertainty, based on the forecast errors of various private and government forecasts over the past 20 years, for real GDP growth, the unemployment rate, and total consumer price inflation. That measure is incorporated graphically in the top panels of figures 4.A, 4.B, and 4.C, which display "fan charts" plotting the median SEP projections for the three variables surrounded by symmetric confidence intervals derived from the forecast errors presented in table 2. If the degree of uncertainty attending these projections is similar to the typical magnitude of past forecast errors and the risks around the projections are broadly balanced, future outcomes of these variables would have about a 70 percent probability of occurring within these confidence intervals. For all three variables, this measure of projection uncertainty is substantial and generally increases as the forecast horizon lengthens.

Note: Error ranges shown are measured as plus or minus the root mean squared error of projections for 1997 through 2016 that were released in the winter by various private and government forecasters. As described in the box "Forecast Uncertainty," under certain assumptions, there is about a 70 percent probability that actual outcomes for real GDP, unemployment, consumer prices, and the federal funds rate will be in ranges implied by the average size of projection errors made in the past. For more information, see David Reifschneider and Peter Tulip (2017), "Gauging the Uncertainty of the Economic Outlook Using Historical Forecasting Errors: The Federal Reserve's Approach," Finance and Economics Discussion Series 2017-020 (Washington: Board of Governors of the Federal Reserve System, February), www.federalreserve.gov/econresdata/feds/2017/files/2017020pap.pdf.

Participants' assessments of the level of uncertainty surrounding their economic projections are shown in the bottom-left panels of figures 4.A, 4.B, and 4.C. Nearly all participants viewed the degree of uncertainty attached to their economic projections about GDP growth, the unemployment rate, and inflation as broadly similar to the average of the past 20 years, a view that was essentially unchanged from September.16 About half of the participants who commented on this topic suggested that uncertainties about the details of the pending tax legislation had raised their assessment of uncertainty for GDP growth, albeit not by enough to tip their assessments into the higher-than-average category.

Because the fan charts are constructed to be symmetric around the median projection, they do not reflect any asymmetries in the balance of risks that participants may see in their economic projections. Accordingly, participants' assessments of the balance of risks to their economic projections are shown in the bottom-right panels of figures 4.A, 4.B, and 4.C. As in September, most participants judged the risks to their projections of real GDP growth, the unemployment rate, headline inflation and core inflation as broadly balanced--in other words, as broadly consistent with a symmetric fan chart. The balance of risks to the economic outlook shifted slightly in the direction of strength, with two more participants seeing upside risks to growth in real GDP than in September and one more seeing risks to the unemployment rate as weighted to the downside. In addition, one more participant than before saw risks to inflation as weighted to the upside.

Participants' assessments of the future path of the federal funds rate consistent with appropriate policy are also subject to considerable uncertainty. Because the Committee adjusts the federal funds rate in response to actual and prospective developments over time in real GDP growth, unemployment, and inflation, uncertainty surrounding the projected path for the funds rate importantly reflects the uncertainties about the path for those key economic variables. Figure 5 provides a graphical representation of this uncertainty, plotting the median SEP projection for the federal funds rate surrounded by confidence intervals derived from the results presented in table 2. As with the macroeconomic variables, forecast uncertainty is substantial and increases for longer horizons.

Forecast Uncertainty

The economic projections provided by the members of the Board of Governors and the presidents of the Federal Reserve Banks inform discussions of monetary policy among policymakers and can aid public understanding of the basis for policy actions. Considerable uncertainty attends these projections, however. The economic and statistical models and relationships used to help produce economic forecasts are necessarily imperfect descriptions of the real world, and the future path of the economy can be affected by myriad unforeseen developments and events. Thus, in setting the stance of monetary policy, participants consider not only what appears to be the most likely economic outcome as embodied in their projections, but also the range of alternative possibilities, the likelihood of their occurring, and the potential costs to the economy should they occur.

Table 2 summarizes the average historical accuracy of a range of forecasts, including those reported in past Monetary Policy Reports and those prepared by the Federal Reserve Board's staff in advance of meetings of the Federal Open Market Committee (FOMC). The projection error ranges shown in the table illustrate the considerable uncertainty associated with economic forecasts. For example, suppose a participant projects that real gross domestic product (GDP) and total consumer prices will rise steadily at annual rates of, respectively, 3 percent and 2 percent. If the uncertainty attending those projections is similar to that experienced in the past and the risks around the projections are broadly balanced, the numbers reported in table 2 would imply a probability of about 70 percent that actual GDP would expand within a range of 2.2 to 3.8 percent in the current year, 1.3 to 4.7 percent in the second year, 0.9 to 5.1 percent in the third year, and 0.8 to 5.2 percent in the fourth year. The corresponding 70 percent confidence intervals for overall inflation would be 1.8 to 2.2 percent in the current year, 1.0 to 3.0 percent in the second year, 0.9 to 3.1 percent in the third year, and 1.0 to 3.0 percent in the fourth year. Figures 4.A through 4.C illustrate these confidence bounds in "fan charts" that are symmetric and centered on the medians of FOMC participants' projections for GDP growth, the unemployment rate, and inflation. However, in some instances, the risks around the projections may not be symmetric. In particular, the unemployment rate cannot be negative; furthermore, the risks around a particular projection might be tilted to either the upside or the downside, in which case the corresponding fan chart would be asymmetrically positioned around the median projection.

Because current conditions may differ from those that prevailed, on average, over history, participants provide judgments as to whether the uncertainty attached to their projections of each economic variable is greater than, smaller than, or broadly similar to typical levels of forecast uncertainty seen in the past 20 years, as presented in table 2 and reflected in the widths of the confidence intervals shown in the top panels of figures 4.A through 4.C. Participants' current assessments of the uncertainty surrounding their projections are summarized in the bottom-left panels of those figures. Participants also provide judgments as to whether the risks to their projections are weighted to the upside, are weighted to the downside, or are broadly balanced. That is, while the symmetric historical fan charts shown in the top panels of figures 4.A through 4.C imply that the risks to participants' projections are balanced, participants may judge that there is a greater risk that a given variable will be above rather than below their projections. These judgments are summarized in the lower-right panels of figures 4.A through 4.C.

As with real activity and inflation, the outlook for the future path of the federal funds rate is subject to considerable uncertainty. This uncertainty arises primarily because each participant's assessment of the appropriate stance of monetary policy depends importantly on the evolution of real activity and inflation over time. If economic conditions evolve in an unexpected manner, then assessments of the appropriate setting of the federal funds rate would change from that point forward. The final line in table 2 shows the error ranges for forecasts of short-term interest rates. They suggest that the historical confidence intervals associated with projections of the federal funds rate are quite wide. It should be noted, however, that these confidence intervals are not strictly consistent with the projections for the federal funds rate, as these projections are not forecasts of the most likely quarterly outcomes but rather are projections of participants' individual assessments of appropriate monetary policy and are on an end-of-year basis. However, the forecast errors should provide a sense of the uncertainty around the future path of the federal funds rate generated by the uncertainty about the macroeconomic variables as well as additional adjustments to monetary policy that would be appropriate to offset the effects of shocks to the economy.

If at some point in the future the confidence interval around the federal funds rate were to extend below zero, it would be truncated at zero for purposes of the fan chart shown in figure 5; zero is the bottom of the lowest target range for the federal funds rate that has been adopted by the Committee in the past. This approach to the construction of the federal funds rate fan chart would be merely a convention; it would not have any implications for possible future policy decisions regarding the use of negative interest rates to provide additional monetary policy accommodation if doing so were appropriate. In such situations, the Committee could also employ other tools, including forward guidance and asset purchases, to provide additional accommodation.

While figures 4.A through 4.C provide information on the uncertainty around the economic projections, figure 1 provides information on the range of views across FOMC participants. A comparison of figure 1 with figures 4.A through 4.C shows that the dispersion of the projections across participants is much smaller than the average forecast errors over the past 20 years.
