Japan-Watching: Yen Repatriation Starts with the Whale

GPIF, one of the largest national pension funds in the world, is likely to rebalance its assets from non-yen bonds to yen bonds, signaling a big turn in Japan’s cross-border capital flows.

[from Japan Macro Advisors, 10 September, 2026]

Key takeaways

  • In 2013, GPIF’s investment committee, chaired by UEDA Kazuo [植田和男], now the BoJ governor, saw a fair chance of a JGB crash within five to ten years. Its CEO priced the crash as the 10-year rising from 0.5% to 3%. Subsequently, GPIF cut its target weight for domestic bonds from 60% to 25% as an emergency measure against abnormally low yields.
  • The 10-year is now at 3%. On my replication of GPIF’s own allocation rule, a real return on JGBs near zero points to a 50% weight in domestic bonds, against 25% today. I expect GPIF to raise the weight, if it has not already started in the September quarter.
  • How GPIF decides its asset allocation and communicates it publicly is a very delicate and political issue. But regardless of how it communicates it, a change in asset allocation is inevitable. In my view, it signifies a big turn in Japan’s cross-border capital flows.

Japan has one of the Largest Pension Funds in the World

Japan has the second largest public pension fund in the world. Norway’s is the biggest, although it is not strictly a pension fund. Canada’s pension funds, when all eight of its variants are added together, come a close third.

Japan set up its first national pension fund in 1961 and it has since gone through various reforms and reorganization over the last 65 years. Its current form is called the Government Pension Investment Fund (GPIF). As explained in a later section, GPIF has a few siblings, and when we add them together, Japan’s public pension funds can be said to be the largest in the world.

Chart 1

GPIF used to invest most of its asset into JGBs

GPIF used to invest the majority of its fund as loans to the national government and into Japanese government bonds (JGBs). At the end of FY2012, 62% of its assets consisted of domestic bonds. However, in 2014 it went through a radical asset reallocation and the target weight for domestic bonds was reduced from 60% to 35%, and then further down to 25% in 2020. Its current target allocation is a clean four-way 25% split into domestic bonds, domestic equity, foreign equity and foreign bonds.

As one of the largest pension funds in the world, its asset allocations attract market attention and there is speculation that it is about to raise its allocation into domestic bonds. In my view, there is indeed a very high chance that GPIF will be raising its allocation into domestic bonds, if it has not already started to do so in the current quarter ending in September 2026.

Chart 2

UEDA in 2013 Saw a Bond Crash Coming

To understand why GPIF is highly likely to raise its allocation into domestic bonds, we need to go back in history to 2013. Why 2013? Of course, it is the year the Bank of Japan (BoJ) started its massive quantitative easing. The 10-year JGB yield started 2013 at 0.8% and it fell to 0.3% by the end of 2015 before briefly hitting a negative rate of -0.3% in 2016. If you were the chairperson of the GPIF investment committee, you would have been concerned about the wisdom of continuing to invest in JGBs at such a policy-driven low rate. The actual chairperson was UEDA Kazuo [植田和男], the current BoJ governor. In the minutes for October 2013, UEDA said, “I think there is a fair chance that bonds will crash at some point in the next five to ten years [unofficial translation].”

The minutes were released only seven years later; otherwise the use of the word “crash” would have been controversial.

GPIF CEO Priced the Crash at 3% in 2014. We Are There Now

If you read through the GPIF minutes between 2013 and 2014, you would see that GPIF officials were increasingly conscious of the precariousness of investing in JGBs. Long story short, as this process was highly political and a sensitive subject, they decided to radically lower the target allocation weight for JGBs to 35% in 2014, presented it as the result of a philosophical change in the way GPIF is managed and how the concept of “risk” should be considered. Investment in JGBs was no longer considered low risk in real terms. The asset allocation for domestic bonds was further lowered to 25% in 2020. The following is what MITANI Takahiro [三谷隆博], the GPIF CEO at the time and an ex-BoJ senior official, said in the October 2014 GPIF minutes.

“Yields are just under 0.5% now, so a move to near 3% would mean a loss of about ¥25 trillion. (…). So I think the clearest way to explain it is that reducing the weight on JGBs to some degree is simply unavoidable [unofficial translation]”

The 2014 cut in the weight was partly an emergency escape

As I wrote earlier, the radical asset reallocation in 2014 was part a shift in the concept of risk from “nominal” to “real”, so that JGB is no longer risk free assets. But the change was also at least partly an emergency measure to escape the abnormally low-yield environment. Then the next natural question is, now that the JGB yields are no longer abnormally low, what should happen to its asset allocation? Pensions are paid in yen, so long-duration Japanese government bonds are a natural match, while GPIF should also be holding some non-yen assets and equities to diversify its assets and protect the overall balance sheet from inflation. In the next section, I will show you a simplified replication of how GPIF decides its asset allocation and what GPIF’s asset allocation could be now that JGB yields are normal.

How GPIF decides its weights

Put simply, GPIF’s target weights are the output of an optimizer with a few rules. Find the portfolio that, at the required real return, has the smallest average shortfall below wage growth in the years when it falls short, and round it to the nearest 5%.

When GPIF last decided to keep the current 25% weight for domestic bonds in 2025, JGBs were assumed to produce a nominal return of 0.5% against wage growth of 1.3%, so a real return of minus 0.8%. Exhibit 1 shows a simplified matrix of weights depending on expected nominal return on bonds and wage growth. The red box shows the assumption behind the 2025 weights decision mentioned above. If we use a higher wage growth assumption of 2.3%, an expected nominal return of 1.8% on bonds gives a weight of 35%. GPIF’s bond portfolio has an average maturity around 10 years, and the 10-year bond is yielding 3% now. A lot of thought and estimation is needed to form a view on the expected real return on domestic bonds, but in my view, it is clear that the minus 0.8% used in their last review is too low given where bond yields are.

Why GPIF kept the weight in 2025 and why circumstances changed

In late 2024 when the GPIF was reviewing the weight as part of its five-year plan, the BoJ was already in the process of exiting from QE and raising its policy rate. However, the JGB market was still in the process of adjustment and bond yields had a lot of room to rise. For example, the 10-year yield was 0.89% at the end of September 2024, rose to 2% by the end of 2025 and now, in September 2026, stands at 3%. You can understand why GPIF decided to keep its weight on domestic bonds unchanged as it would have incurred capital losses on bond purchases in 2025. But in my view, as I wrote in the report “The Long Climb in JGB Yields Is Nearly Over” [archived PDF], long bond yields are getting closer to a stability point. If the GPIF board shares my view, it is a good time to think about raising its target weight into domestic yen bonds.

The Whale Problem and the Washington Problem

How high should the new weight be for domestic bonds? The reality of determining appropriate weights and how to announce it is a lot harder than the simplified model I explained above. Other than forming a reasonable view on the expected real return on asset classes, there are a few factors that complicate the process.

Firstly, GPIF needs to think about how such an announcement would affect the market. GPIF is what financial market professionals call a whale, a massive investor whose investment decisions sway market prices. There is also a related argument that given the dominance of GPIF in the domestic market, GPIF should be increasing its asset weight abroad to reduce its impact on domestic asset markets.

Secondly, changing asset allocation weights carries political considerations. If GPIF decides to raise the target weight for domestic bonds, foreign bonds are the likely asset class whose weight will go down. More than 50% of its foreign bonds are in US dollars. With all the news circulating in the market now, Scott Bessent will not like a public announcement that one of the largest pension funds in the world is reducing its purchase of US treasuries. There are domestic political considerations as well, as the Takaichi government contemplates how best to fund its deficits.

These are the issues GPIF officials must be debating. How GPIF decides its asset allocation in the near future will be a revealing case study for those who want to study how policy-making works in Japan. Those who are interested in this topic should read the transcripts of an interesting government committee in 2014 that focused on how GPIF could shield itself from political meddling. Guess who chaired the committee? UEDA Kazuo [植田和男].

Whatever the near-term decision GPIF makes regarding its target weight, I think it is fairly clear that GPIF should be increasing its investment into domestic bonds. The following table shows how much GPIF could buy in net terms, depending on the eventual rise in the target weight.

How much GPIF buys: ¥32tn at 35%, ¥80tn at 50%

Three things in this table matter for the market. GPIF is allowed to deviate its asset allocation by six points either side of 25% without any announcement, so 39% target is already possible without any public announcement. In 2014 GPIF moved inside its band first and announced the new portfolio afterwards, and I would expect the same sequence this time. Second, these are static figures, which do not account for the growth of the fund over time.

The sister funds move with the whale

As mentioned earlier, GPIF has a few siblings. The Pension Fund Association for Local Government Officials (¥35.5tn), the Federation of National Public Service Personnel Mutual Aid Associations, known as KKR (¥11.5tn), and the Promotion and Mutual Aid Corporation for Private Schools of Japan (¥4.9tn) manage the pension reserves of local government employees, national government employees and private-school teachers. These sisters run their funds on the same 25/25/25/25 model, and with the legacy reserves they also run, they hold a further ¥87tn on top of GPIF’s.

Conclusion

GPIF cut its domestic bond weight from 60% to 35% in 2014, and later to 25%, to safeguard its assets from the manipulated low JGB yields at the time and the eventual crash they foresaw. That crash, as GPIF’s CEO MITANI defined it in 2014, has now happened with the 10-year yield rising to 3%. In my view, JGB yields have largely normalized and there is no emergency reason to avoid domestic bonds. It is only natural that GPIF would raise its allocation into domestic bonds, although how GPIF communicates this publicly is a touchy issue they need to figure out. When GPIF raises its domestic bond allocation, foreign bonds are the likely asset class to take the hit. GPIF publishes quarterly results and the next publication for the end-September 2026 quarter, expected in early November 2026, will be closely watched. Judging from market movements in the last few weeks, the market has started to sense that what I described in this article is already happening and Japanese money is starting to come back to the yen. While it should be characterized as rebalancing, rather than a repatriation, it seems we are observing a big turn in Japanese cross-border capital flows.

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

OFR Working Paper Finds Cash Biases Measurement of the Stock Return Correlations

[from the U.S. Office of Financial Research]

Today, the U.S. Office of Financial Research published a working paper, “Cash-Hedged Stock Returns” [archived PDF], and an accompanying blog (below), regarding firms’ cash holdings and the implications for asset prices and financial stability.

Cash holdings are important for financial stability because of their value in crises.  Corporate cash piles vary across companies and over time. Firms’ cash holdings typically earn low returns, and their cash returns are correlated across firms.  Thus, the asset pricing results are important for investors managing a portfolio’s risk and policymakers concerned about sources of vulnerability.

The working paper [archived PDF] shows how investors can hedge cash on firms’ balance sheets when making portfolio choices.  Cash generates variation in beta estimates, and the working paper decomposes stock betas into components that depend on the firm’s cash holding, return on cash, and cash-hedged return. Common asset pricing premia have large implicit cash positions, and portfolios of cash-hedged premia often have higher Sharpe ratios, used by investors to understand a return on investment, because of the correlation between firms’ cash returns. The paper shows the value of a dollar increased in 2020, and firms hold cash because they are riskier.

OFR Finds Large Cash Holdings Can Lead to Mismeasuring Risk

[from the OFR blog, by Sharon Ross]

Cash is necessary for companies’ operations. Firms use cash to make payments, finance investments, and manage risk. But holding cash comes at a cost: its low pecuniary return. Published today by the OFR, the working paper, “Cash-Hedged Stock Returns” [archived PDF], shows that the cash returns of publicly traded, non-financial firms are correlated. Since cash returns are a part of equity returns, investors that are using equity return correlations to measure risk can mismeasure risk.

We show the importance of cash for systemic risk by documenting the value of cash in crises, showing that firms hold cash in part due to risk management and studying how cash biases the measurement of the interconnectedness of stock returns. The consequences of cash are important for policymakers monitoring aggregate risks, and sources of market vulnerability and for investors making portfolio choices.

Cash holdings are important for financial stability because of their value in crises. Several papers document a “dash for cash” during the initial panicked stages of the coronavirus 2019 (COVID-19) pandemic when firms rushed to hold cash in their coffers. The dash for cash was driven by firms drawing down on lines of credit from banks, which in turn affected bank lending. The dash for cash highlighted the critical role of firms’ cash holdings and returns in understanding risk in the financial system.

We show the value of a dollar increased in 2020. Moreover, our results show that firms may hold cash because they are riskier, as opposed to firms with high cash shares being less risky due to their cash holdings. Our results are consistent with a precautionary savings motive for holding cash. In other words, firms hold cash for risk management, in part to weather bad times.

Cash is a growing share of public firms’ assets. The value-weighted U.S. stock market held 22% of its assets in cash in December 2020 compared to 8% in the 1980s. An investor buying the market in 2020 ends up with an implicit cash position three times larger than in 1980. Individual firms vary in how much cash they hold. As cash holdings increase, it is important to understand how cash holdings affect returns, which in turn impacts who chooses to invest in the firms.

Cash returns are correlated across firms, and cash biases measurement of the interconnectedness of stock returns, making it a risk for financial stability. As a result, the asset pricing results are important both for investors managing portfolio risk and for policymakers concerned about interconnected returns.

We argue that the value of corporate cash is distinct, and we can separate the value of cash and the value of the firm’s primary business. We show how investors can explicitly account for the effect of corporate cash holdings when forming a portfolio. When an investor owns stock in a company with substantial cash, the investor has an implicit cash position managed by the company—something the investor might not intend. We argue that investors should account for the effect of corporate cash holdings in the portfolio decision to measure a portfolio’s risk. Firms’ cash management is not consistent across firms, and investors may want to manage their cash positions themselves. Policymakers should be aware of investors’ choices in cash because of investors’ portfolio risk and the implications for aggregate risk.

We separate a company’s stock return into its cash and non-cash components, and we show that using the non-cash return gives a more informative correlation structure across stocks. In other words, if investors take out the correlated cash returns, the remaining return is less correlated, yielding portfolios that provide better diversification. We show how cash holdings and returns affect the returns of standard asset pricing strategies and asset pricing models like the capital asset pricing model (CAPM).

As cash holdings of public firms increase, it is important that policymakers understand how these increases impact stock returns for both individual firms and the aggregate market. Cash returns are correlated across firms, and cash biases the measurement of the interconnectedness of stock returns. This correlation is important both for investors who are managing a portfolio’s risk and policymakers concerned about sources of vulnerability stemming from interconnected returns.

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.
