FRBSF Economic Letter: Can Monetary Policy Tame Rent Inflation?

[from the Federal Reserve Bank of San Francisco Economic Letter]

by Zheng Liu and Mollie Pepper

Rent inflation has surged since early 2021. Because the cost of housing is an important component of total U.S. consumer spending, high rent inflation has contributed to elevated levels of overall inflation. Evidence suggests that, as monetary policy tightening cools housing markets, it can also reduce rent inflation, although this tends to adjust relatively slowly. A policy tightening equivalent to a 1 percentage point increase in the federal funds rate could reduce rent inflation as much as 3.2 percentage points over 2½ years.

“We’ve had a time of red-hot housing market all over the country… Shelter inflation is going to remain high for some time. We’re looking for it to come down, but it’s not exactly clear when that will happen. Hope for the best, plan for the worst.”

Federal Reserve Chair Jerome Powell (2022)

The rapid run-up of shelter costs—both house prices and rents—during the recovery from the pandemic has raised questions about how inflation pressures might affect housing affordability. Since March 2022, the Federal Reserve has rapidly lifted its federal funds rate target from near zero to over 4%, and policymakers have signaled that they are open to keeping the monetary policy stance sufficiently restrictive to return inflation to the longer-run goal of 2% on average. The tightened financial conditions following those policy changes, especially the surge in mortgage interest rates, have helped cool house price growth. However, rent inflation remains elevated.

This Economic Letter examines the effectiveness of monetary policy tightening for reducing rent inflation. We estimate that, during the period from 1988 to 2019, a policy tightening equivalent to a 1 percentage point increase in the federal funds rate can reduce rent inflation—measured by 12-month percentage changes in the personal consumption expenditures (PCE) housing price index—by about 3.2 percentage points, but the full impact takes about 2½ years to materialize. Based on housing costs’ share in total PCE, this translates to a reduction in headline PCE inflation of about 0.5 percentage point over the same time horizon.

Rising housing costs

Following the COVID-19 recession, house prices and rents both surged in the United States. For example, the 12-month growth rate of Standard & Poor’s CoreLogic Case-Shiller Home Price Index accelerated from about 10% in December 2020 to over 20% in March 2022. After the Federal Reserve started raising the target for the federal funds rate in March, house price growth has slowed significantly, to about 9% in October 2022.

Rent inflation also accelerated during the pandemic period. Figure 1 shows that rent inflation—measured using 12-month changes in the PCE housing price index and including rents for tenant-occupied housing and imputed rents for owner-occupied housing—rose from a low point of about 2% in early 2021 to 7.7% by December 2022, the highest level since 1986. During the same period, rent inflation measured by 12-month changes in the shelter component of the consumer price index (CPI) experienced a similar increase. Thus, following the tightening of monetary policy, house price growth has slowed but rent inflation continues to rise.

Economic theory suggests that some common forces such as changes in housing demand can drive both rents and house prices. For example, the expansion of remote work since the COVID-19 pandemic has increased demand for housing, raising both house prices and rents (Kmetz, Mondragon, and Wieland 2022). To the extent that the stream of current and future rents reflects the fundamental value of a house, house prices can be a leading indicator of future rent inflation (Lansing, Oliveira, and Shapiro 2022). Thus, monetary policy can affect both house prices and rents by cooling housing demand.

Housing demand responds to changes in financial conditions, such as increases in mortgage interest rates. However, theory suggests that house prices are more sensitive than rental prices to changes in financial conditions, because home purchases typically require longer-term mortgage financing. In addition, unlike rents, house prices can be partly driven by investor sentiments or beliefs, which explains the observed larger swings in house prices than in rents over business cycles (Dong et al. 2022). Long-term rental contracts can also contribute to slow adjustments in rent inflation.

Rent inflation is an important contributor to overall inflation because housing costs are an important component of total consumption expenditures. On average, housing expenditures represent about 15% of total PCE and 25% of the services component of PCE. In CPI, shelter costs represent an even larger share, accounting for about 30% of total consumption of all urban consumers and about 40% of core consumption expenditures excluding volatile food and energy components.

The contribution of rent inflation to overall PCE inflation has increased since early 2021. As Figure 2 shows, in the first quarter of 2021, rent inflation accounted for about 22% of the four-quarter change in the PCE services price index, excluding energy: 0.5 of the 2.3 percentage points increase in service prices was attributable to rent inflation. By the third quarter of 2022, the contribution of rent inflation had climbed to about one-third, or 1.5 of the 4.7 percentage point increase in service prices.

Measuring policy effects

Given the rising contribution of rent inflation to overall inflation, it is important to assess the quantitative effects of monetary policy tightening on rent inflation.

For our analysis, we use a measure of monetary policy surprises constructed by Bauer and Swanson (2022). Their measure focuses on high-frequency changes in financial market indicators within a short period surrounding the Federal Open Market Committee (FOMC) policy announcements. If the public fully anticipates a policy change, then the financial market would not react to new policy announcements. However, if the market does react to an announcement, then the policy change must contain a surprise element. Thus, changes in financial market indicators, such as the price of Eurodollar futures, in a narrow window around an FOMC announcement can capture policy surprises. In practice, however, the data constructed this way are not complete surprises because they can be predicted by some macro and financial variables shortly before FOMC announcements. We follow the approach of Bauer and Swanson (2022) to purge the influences of those macro and financial variables from the measure of policy surprises. We use the resulting quarterly time series to measure monetary policy shocks, with a sample period from 1988 to 2019.

We then use a local projections model—a statistical tool proposed by Jordà (2005)—to project how rent inflation responds over time to a tightening of monetary policy equivalent to a 1 percentage point unanticipated increase in the federal funds rate in a given quarter. The model takes into account how monetary policy shocks interact with other macroeconomic variables, including lags of rent inflation, real GDP growth, and core PCE inflation.

In the final step, we compute the responses of rent inflation relative to its preshock level over a period up to 20 quarters after the initial increase in the federal funds rate.

Gradual impact of policy tightening on rent inflation

Figure 3 shows the response of rent inflation during the first 20 quarters after an unanticipated tightening of monetary policy (solid blue line). The shaded area shows the confidence band, indicating the statistical uncertainty in estimating the responses. Under the assumption that the model is correct, the shaded area contains the actual value of the rent inflation responses to the monetary policy shock roughly two-thirds of the time. The policy shock is normalized such that it is equivalent to a 1 percentage point unanticipated increase in the federal funds rate.

Note: Response of rent inflation to a monetary policy shock equivalent to a 1 percentage point surprise increase in the federal funds rate. Shaded region shows 68% confidence band around the estimate.

The figure shows that monetary policy tightening has significant and gradual effects on rent inflation. On impact, a 1 percentage point increase in the federal funds rate reduces rent inflation about 0.6 percentage point relative to its preshock level. Over time, rent inflation declines gradually, falling about 3.2 percentage points in the 10 quarters following the impact. The slow adjustment in rent inflation partly reflects the stickiness in nominal rents due to long-term rental contracts. Since housing expenditures account for about 15% of total PCE, this estimate translates to a reduction in headline PCE inflation of about 0.5 percentage point, stemming from the decline in rent inflation over a period of 2½ years.

The rent component of PCE is measured based on average rents, including those locked in long-term rental contracts, which are slow to adjust to changes in economic and financial conditions. Rents on new leases, however, are more flexible. For example, the 12-month growth in Zillow’s observed rent index, which measures changes in asking rents on new leases, has slowed significantly since March 2022 (see Figure 4). Asking rents are typically a leading indicator of future average rents. Thus, the slowdown in asking rent growth could portend lower future rent inflation.

Conclusion

Rents are an important component of consumer expenditures. Recent surges in rent inflation have led to concerns that overall inflation might stay persistently high despite tightening of monetary policy. We present evidence that monetary policy tightening is effective for reducing rent inflation, although the full impact takes time to materialize. A policy tightening equivalent to a 1 percentage point increase in the federal funds rate can reduce rent inflation up to 3.2 percentage points over the course of 2½ years. This translates to a maximum reduction in headline PCE inflation of about 0.5 percentage point over the same time horizon. Although average rents are slow to respond to policy changes, growth of asking rents on new leases has started to slow following recent monetary policy tightening. Our finding suggests that this tightening will gradually bring rent inflation down over time, thereby helping to reduce overall inflation.

Economics-Watching: FedViews for January 2023

[from the Federal Reserve Bank of San Francisco]

Adam Shapiro, vice president at the Federal Reserve Bank of San Francisco, stated his views on the current economy and the outlook as of January 12, 2023.

  • While continuing to cool over the last several months, 12-month inflation remains at historically high levels. The headline personal consumption expenditures (PCE) price index rose 5.5% in November 2022 from a year earlier. This marks a decline in inflation to a level last observed in October 2021, but still well above the Fed’s longer-run goal of 2%. A portion of the inflation moderation is attributable to recent declines in energy prices. Core PCE inflation, which removes food and energy prices, has shown less easing.
  • Owing to fiscal relief efforts and lower household spending over the course of the pandemic, consumers accumulated over $2 trillion dollars in excess savings, based on pre-pandemic trends. Since then, consumers have drawn down over half of this excess savings which has helped support recent growth in personal consumption expenditures. A considerable amount of accumulated savings remains for some consumers to support spending in 2023.
  • In the wake of the pandemic, consumer spending patterns shifted away from services towards goods. While there appears to be some normalization of spending behavior, this shift has generally persisted. Real goods spending remains significantly above its pre-pandemic trend, driven by strong demand for durables such as furniture, electronics, and recreational goods. Spending on services has shown a resurgence but remains below its pre-pandemic trend.
  • Supply chain bottlenecks for materials and labor remain a constraint on production, although there are some recent signs of easing. The fraction of manufacturers who reported operating below capacity due to insufficient materials peaked in late 2021 and has moderately declined over the past year. However, the fraction of manufacturers reporting insufficient labor has persisted at high levels.
  • The labor market remains tight, despite some signs of cooling. The number of available jobs remains well above the number of available workers, although vacancy postings have been trending down in recent months. The tight labor market has put continued upward pressure on wages and labor market turnover.
  • A decomposition of headline PCE inflation into supply– and demand-driven components shows that both supply and demand factors are responsible for the recent rise in inflation. The surge in inflation in early 2021 was mainly due to an increase in demand-driven factors. Subsequently, supply factors became more prevalent for the remainder of 2021. Supply-driven inflation has moderated significantly over recent months, while demand-driven inflation remains elevated.
  • The Federal Open Market Committee (FOMC) raised the federal funds rate by 50 basis points at the December meeting to a range of 4.25 to 4.5%. This cycle of continued rate increases since March of last year represents the fastest pace of monetary policy tightening in 40 years. The increase in the federal funds rate has been accompanied by a gradual reduction in the size of the Federal Reserve’s balance sheet.
  • Economic activity in sectors such as housing, which is sensitive to rising interest rates, has slowed considerably in recent months. Housing starts have fallen steadily over the past year, as have other housing market indicators, such as existing home sales and house prices.
  • Although the labor market is currently very strong, financial markets are pointing to some downside risks. Namely, the difference between longer- and shorter-term interest rates has turned negative, which historically tends to occur immediately preceding recessions. It remains unclear whether lower longer-term yields are indicative of anticipated slower growth or lower inflation.
  • Short-term inflation expectations remain elevated relative to their pre-pandemic levels in December 2019. Consumers are expecting prices to rise 5% this year, while professional forecasters are expecting prices to rise 3.5%. Longer-term inflation expectations remain more subdued, indicating that both consumers and professionals believe inflation pressures will eventually dissipate.
  • Rent inflation is expected to remain high over the next year. The prices for asking rents have grown quite substantially over the last two years. As new leases begin and existing leases are renewed, these higher asking rents will flow into the stock of rental units, putting upward pressure on rent inflation.
  • We are expecting inflation to moderate over the next few years as monetary policy continues to restrain demand and supply bottlenecks continue to ease. We anticipate that it will take some time for inflation to reach the Fed’s longer-run goal of 2%.
Inflation is cooling, but remains very high
Savings are boosting consumer demand
Goods consumption remains elevated
Supply shortages are prevalent, but easing
Labor market remains tight, but is cooling
Both supply and demand drive inflation
Monetary policy tightening is having real effects
Yield curve is inverted, signaling recession risk
Short-term inflation expectations remain elevated
High rent inflation is in the pipeline
Inflation likely to remain above 2% for some time

Federal Reserve Review of Monetary Policy Strategy, Tools, and Communications: Some Preliminary Views

(Speech by Governor Lael Brainard, at the Presentation of the 2019 William F. Butler Award New York Association for Business Economics, New York, New York)

It is a pleasure to be here with you. It is an honor to join the 45 outstanding economic researchers and practitioners who are past recipients of the William F. Butler Award. I want to express my deep appreciation to the New York Association for Business Economics (NYABE) and NYABE President Julia Coronado.

I will offer my preliminary views on the Federal Reserve’s review of its monetary policy strategy, tools, and communications after first touching briefly on the economic outlook. These remarks represent my own views. The framework review is ongoing and will extend into 2020, and no conclusions have been reached at this time.1

Outlook and Policy

There are good reasons to expect the economy to grow at a pace modestly above potential over the next year or so, supported by strong consumers and a healthy job market, despite persistent uncertainty about trade conflict and disappointing foreign growth. Recent data provide some reassurance that consumer spending continues to expand at a healthy pace despite some slowing in retail sales. Consumer sentiment remains solid, and the employment picture is positive. Housing seems to have turned a corner and is poised for growth following several weak quarters.

Business investment remains downbeat, restrained by weak growth abroad and trade conflict. But there is little sign so far that the softness in trade, manufacturing, and business investment is affecting consumer spending, and the effect on services has been limited.

Employment remains strong. The employment-to-population ratio for prime-age adults has moved up to its pre-recession peak, and the three-month moving average of the unemployment rate is near a 50-year low.2 Monthly job gains remain above the pace needed to absorb new entrants into the labor force despite some slowing since last year. And initial claims for unemployment insurance—a useful real-time indicator historically—remain very low despite some modest increases.

Data on inflation have come in about as I expected, on balance, in recent months. Inflation remains below the Federal Reserve’s 2 percent symmetric objective, which has been true for most of the past seven years. The price index for core personal consumption expenditures (PCE), which excludes food and energy prices and is a better indicator of future inflation than overall PCE prices, increased 1.7 percent over the 12 months through September.

Foreign growth remains subdued. While there are signs that the decline in euro-area manufacturing is stabilizing, the latest indicators on economic activity in China remain sluggish, and the news in Japan and in many emerging markets has been disappointing. Overall, it appears third-quarter foreign growth was weak, and the latest indicators point to little improvement in the fourth quarter.

More broadly, the balance of risks remains to the downside, although there has been some improvement in risk sentiment in recent weeks. The risk of a disorderly Brexit in the near future has declined significantly, and there is some hope that a U.S.China trade truce could avert additional tariffs. While risks remain, financial market indicators suggest market participants see a diminution in such risks, and probabilities of recessions from models using market data have declined.

The baseline is for continued moderate expansion, a strong labor market, and inflation moving gradually to our symmetric 2 percent objective. The Federal Open Market Committee (FOMC) has taken significant action to provide insurance against the risks associated with trade conflict and weak foreign growth against a backdrop of muted inflation. Since July, the Committee has lowered the target range for the federal funds rate by ¾ percentage point, to the current range of 1½ to 1¾ percent. It will take some time for the full effect of this accommodation to work its way through economic activity, the labor market, and inflation. I will be watching the data carefully for signs of a material change to the outlook that could prompt me to reassess the appropriate path of policy.

Review

The Federal Reserve is conducting a review of our monetary policy strategy, tools, and communications to make sure we are well positioned to advance our statutory goals of maximum employment and price stability.3 Three key features of today’s new normal call for a reassessment of our monetary policy strategy: the neutral rate is very low here and abroad, trend inflation is running below target, and the sensitivity of price inflation to resource utilization is very low.4

First, trend inflation is below target.5 Underlying trend inflation appears to be running a few tenths below the Committee’s symmetric 2 percent objective, according to various statistical filters. This raises the risk that households and businesses could come to expect inflation to run persistently below our target and change their behavior in a way that reinforces that expectation. Indeed, with inflation having fallen short of 2 percent for most of the past seven years, inflation expectations may have declined, as suggested by some survey-based measures of long-run inflation expectations and by market-based measures of inflation compensation.

Second, the sensitivity of price inflation to resource utilization is very low. This is what economists mean when they say that the Phillips curve is flat. A flat Phillips curve has the important advantage of allowing employment to continue expanding for longer without generating inflationary pressures, thereby providing greater opportunities to more people. But it also makes it harder to achieve our 2 percent inflation objective on a sustained basis when inflation expectations have drifted below 2 percent.

Third, the long-run neutral rate of interest is very low, which means that we are likely to see more frequent and prolonged episodes when the federal funds rate is stuck at its effective lower bound (ELB).6 The neutral rate is the level of the federal funds rate that would keep the economy at full employment and 2 percent inflation if no tailwinds or headwinds were buffeting the economy. A variety of forces have likely contributed to a decline in the neutral rate, including demographic trends in many large economies, some slowing in the rate of productivity growth, and increases in the demand for safe assets. When looking at the Federal Reserve’s Summary of Economic Projections (SEP), it is striking that the Committee’s median projection of the longer-run federal funds rate has moved down from 4¼ percent to 2½ percent over the past seven years.7 A similar decline can be seen among private forecasts.8 This decline means the conventional policy buffer is likely to be only about half of the 4½ to 5 percentage points by which the FOMC has typically cut the federal funds rate to counter recessionary pressures over the past five decades.

This large loss of policy space will tend to increase the frequency or length of periods when the policy rate is pinned at the ELB, unemployment is elevated, and inflation is below target.9 In turn, the experience of frequent or extended periods of low inflation at the ELB risks eroding inflation expectations and further compressing the conventional policy space. The risk is a downward spiral where conventional policy space gets compressed even further, the ELB binds even more frequently, and it becomes increasingly difficult to move inflation expectations and inflation back up to target. While consumers and businesses might see very low inflation as having benefits at the individual level, at the aggregate level, inflation that is too low can make it very challenging for monetary policy to cut the short-term nominal interest rate sufficiently to cushion the economy effectively.10

The experience of Japan and of the euro area more recently suggests that this risk is real. Indeed, the fact that Japan and the euro area are struggling with this challenging triad further complicates our task, because there are important potential spillovers from monetary policy in other major economies to our own economy through exchange rate and yield curve channels.11

In light of the likelihood of more frequent episodes at the ELB, our monetary policy review should advance two goals. First, monetary policy should achieve average inflation outcomes of 2 percent over time to re-anchor inflation expectations at our target. Second, we need to expand policy space to buffer the economy from adverse developments at the ELB.

Achieving the Inflation Target

The apparent slippage in trend inflation below our target calls for some adjustments to our monetary policy strategy and communications. In this context and as part of our review, my colleagues and I have been discussing how to better anchor inflation expectations firmly at our objective. In particular, it may be helpful to specify that policy aims to achieve inflation outcomes that average 2 percent over time or over the cycle. Given the persistent shortfall of inflation from its target over recent years, this would imply supporting inflation a bit above 2 percent for some time to compensate for the period of underperformance.

One class of strategies that has been proposed to address this issue are formal “makeup” rules that seek to compensate for past inflation deviations from target. For instance, under price-level targeting, policy seeks to stabilize the price level around a constant growth path that is consistent with the inflation objective.12 Under average inflation targeting, policy seeks to return the average of inflation to the target over some specified period.13

To be successful, formal makeup strategies require that financial market participants, households, and businesses understand in advance and believe, to some degree, that policy will compensate for past misses. I suspect policymakers would find communications to be quite challenging with rigid forms of makeup strategies, because of what have been called time-inconsistency problems. For example, if inflation has been running well below—or above—target for a sustained period, when the time arrives to maintain inflation commensurately above—or below—2 percent for the same amount of time, economic conditions will typically be inconsistent with implementing the promised action. Analysis also suggests it could take many years with a formal average inflation targeting framework to return inflation to target following an ELB episode, although this depends on difficult-to-assess modeling assumptions and the particulars of the strategy.14

Thus, while formal average inflation targeting rules have some attractive properties in theory, they could be challenging to implement in practice. I prefer a more flexible approach that would anchor inflation expectations at 2 percent by achieving inflation outcomes that average 2 percent over time or over the cycle. For instance, following five years when the public has observed inflation outcomes in the range of 1½ to 2 percent, to avoid a decline in expectations, the Committee would target inflation outcomes in a range of, say, 2 to 2½ percent for the subsequent five years to achieve inflation outcomes of 2 percent on average overall. Flexible inflation averaging could bring some of the benefits of a formal average inflation targeting rule, but it would be simpler to communicate. By committing to achieve inflation outcomes that average 2 percent over time, the Committee would make clear in advance that it would accommodate rather than offset modest upward pressures to inflation in what could be described as a process of opportunistic reflation.15

Policy at the ELB

Second, the Committee is examining what monetary policy tools are likely to be effective in providing accommodation when the federal funds rate is at the ELB.16 In my view, the review should make clear that the Committee will actively employ its full toolkit so that the ELB is not an impediment to providing accommodation in the face of significant economic disruptions.

The importance and challenge of providing accommodation when the policy rate reaches the ELB should not be understated. In my own experience on the international response to the financial crisis, I was struck that the ELB proved to be a severe impediment to the provision of policy accommodation initially. Once conventional policy reached the ELB, the long delays necessitated for policymakers in nearly every jurisdiction to develop consensus and take action on unconventional policy sapped confidence, tightened financial conditions, and weakened recovery. Economic conditions in the euro area and elsewhere suffered for longer than necessary in part because of the lengthy process of building agreement to act decisively with a broader set of tools.

Despite delays and uncertainties, the balance of evidence suggests forward guidance and balance sheet policies were effective in easing financial conditions and providing accommodation following the global financial crisis.17 Accordingly, these tools should remain part of the Committee’s toolkit. However, the quantitative asset purchase policies that were used following the crisis proved to be lumpy both to initiate at the ELB and to calibrate over the course of the recovery. This lumpiness tends to create discontinuities in the provision of accommodation that can be costly. To the extent that the public is uncertain about the conditions that might trigger asset purchases and how long the purchases would be sustained, it undercuts the efficacy of the policy. Similarly, significant frictions associated with the normalization process can arise as the end of the asset purchase program approaches.

For these reasons, I have been interested in exploring approaches that expand the space for targeting interest rates in a more continuous fashion as an extension of our conventional policy space and in a way that reinforces forward guidance on the policy rate.18 In particular, there may be advantages to an approach that caps interest rates on Treasury securities at the short-to-medium range of the maturity spectrum—yield curve caps—in tandem with forward guidance that conditions liftoff from the ELB on employment and inflation outcomes.

To be specific, once the policy rate declines to the ELB, this approach would smoothly move to capping interest rates on the short-to-medium segment of the yield curve. The yield curve ceilings would transmit additional accommodation through the longer rates that are relevant for households and businesses in a manner that is more continuous than quantitative asset purchases. Moreover, if the horizon on the interest rate caps is set so as to reinforce forward guidance on the policy rate, doing so would augment the credibility of the yield curve caps and thereby diminish concerns about an open-ended balance sheet commitment. In addition, once the targeted outcome is achieved, and the caps expire, any securities that were acquired under the program would roll off organically, unwinding the policy smoothly and predictably. This is important, as it could potentially avoid some of the tantrum dynamics that have led to premature steepening at the long end of the yield curve in several jurisdictions.

Forward guidance on the policy rate will also be important in providing accommodation at the ELB. As we saw in the United States at the end of 2015 and again toward the second half of 2016, there tends to be strong pressure to “normalize” or lift off from the ELB preemptively based on historical relationships between inflation and employment. A better alternative would have been to delay liftoff until we had achieved our targets. Indeed, recent research suggests that forward guidance that commits to delay the liftoff from the ELB until full employment and 2 percent inflation have been achieved on a sustained basis—say over the course of a year—could improve performance on our dual-mandate goals.19

To reinforce this commitment, the forward guidance on the policy rate could be implemented in tandem with yield curve caps. For example, as the federal funds rate approaches the ELB, the Committee could commit to refrain from lifting off the ELB until full employment and 2 percent inflation are sustained for a year. Based on its assessment of how long this is likely take, the Committee would then commit to capping rates out the yield curve for a period consistent with the expected horizon of the outcome-based forward guidance. If the outlook shifts materially, the Committee could reassess how long it will take to get inflation back to 2 percent and adjust policy accordingly. One benefit of this approach is that the forward guidance and the yield curve ceilings would reinforce each other.

The combination of a commitment to condition liftoff on the sustained achievement of our employment and inflation objectives with yield curve caps targeted at the same horizon has the potential to work well in many circumstances. For very severe recessions, such as the financial crisis, such an approach could be augmented with purchases of 10-year Treasury securities to provide further accommodation at the long end of the yield curve. Presumably, the requisite scale of such purchases—when combined with medium-term yield curve ceilings and forward guidance on the policy rate—would be relatively smaller than if the longer-term asset purchases were used alone.

Monetary Policy and Financial Stability

Before closing, it is important to recall another important lesson of the financial crisis: The stability of the financial system is important to the achievement of the statutory goals of full employment and 2 percent inflation. In that regard, the changes in the macroeconomic environment that underlie our monetary policy review may have some implications for financial stability. Historically, when the Phillips curve was steeper, inflation tended to rise as the economy heated up, which prompted the Federal Reserve to raise interest rates. In turn, the interest rate increases would have the effect of tightening financial conditions more broadly. With a flat Phillips curve, inflation does not rise as much as resource utilization tightens, and interest rates are less likely to rise to restrictive levels. The resulting lower-for-longer interest rates, along with sustained high rates of resource utilization, are conducive to increasing risk appetite, which could prompt reach-for-yield behavior and incentives to take on additional debt, leading to financial imbalances as an expansion extends.

To the extent that the combination of a low neutral rate, a flat Phillips curve, and low underlying inflation may lead financial stability risks to become more tightly linked to the business cycle, it would be preferable to use tools other than tightening monetary policy to temper the financial cycle. In particular, active use of macroprudential tools such as the countercyclical buffer is vital to enable monetary policy to stay focused on achieving maximum employment and average inflation of 2 percent on a sustained basis.

Conclusion

The Federal Reserve’s commitment to adapt our monetary policy strategy to changing circumstances has enabled us to support the U.S. economy throughout the expansion, which is now in its 11th year. In light of the decline in the neutral rate, low trend inflation, and low sensitivity of inflation to slack as well as the consequent greater frequency of the policy rate being at the effective lower bound, this is an important time to review our monetary policy strategy, tools, and communications in order to improve the achievement of our statutory goals. I have offered some preliminary thoughts on how we could bolster inflation expectations by achieving inflation outcomes of 2 percent on average over time and, when policy is constrained by the ELB, how we could combine forward guidance on the policy rate with caps on the short-to-medium segment of the yield curve to buffer the economy against adverse developments.
