These remarks represent my own views, which do not necessarily represent those of the Federal
Reserve Board or the Federal Open Market Committee.
The economy appears to be at a transition. We are closing in on full employment, inflation is
moving gradually toward our target, foreign growth is on more solid footing, and risks to the
outlook are as close to balanced as they have been in some time. Assuming continued progress,
it will likely be appropriate soon to remove additional accommodation, continuing on a gradual
path.
As normalization of the federal funds rate gets further under way, monetary policy too is
approaching a transition, prompting increased focus on the balance sheet. How the federal funds
rate and the balance sheet should be adjusted individually and in combination depends on the
degree to which they are substitutes, their relative precision, and the degree to which their effects
on the economy are well understood.
Let me start with the outlook and then turn to policy.
Progress at Home and Abroad
Over the past several quarters, we have seen improvement in inflation and activity both at home
and abroad following a period when the drag on domestic activity from abroad was considerable.
Between the middle of 2014 and 2016, a combination of notable fragilities and risks in large
foreign economies, elevated sensitivity of the dollar to policy divergence, a sharp decline in oil
prices, and financial markets' heightened sensitivity to these downside risks slowed progress in
the U.S. economy and the adjustment of monetary policy to an extent few had anticipated. After
being an important constraint in the past few years, the external environment currently appears
more benign than it has been for some time, even though risks remain.
Near-term risks to the United States from abroad appear to have diminished. Recoveries are
gaining traction in China, Europe, and Japan in part reflecting greater confidence in their
respective policy environments. The improvement in the global risk outlook was also helped by
the continued economic progress and the gradual pace of monetary policy adjustment in the
United States last year.
In recent quarters, market participants appear more confident that China has the will and
capacity to maintain its exchange rate regime, while achieving its growth targets, although there
is a tension with high credit growth that will eventually need to be addressed. Early last year,
China's gross domestic product (GDP) growth, which had averaged nearly 8 percent over the
previous five years, was only a little above an annual rate of 5 percent in the first quarter,
according to official data, and many observers believe that actual growth was weaker. Relatively
large discrete declines in the renminbi against the dollar and a surge in private-sector investment
outflows led to considerable volatility in foreign exchange markets and financial markets more
broadly.
In response, Chinese authorities boosted the supply of credit, ramped up fiscal stimulus, initiated
new communications regarding the exchange rate, and clamped down on capital outflows.
These actions appear to have stabilized growth and calmed fears of financial instability
stemming from a sudden large devaluation in the renminbi. GDP growth rebounded to an
average annual pace of over 7 percent in the final three quarters of the year. The exchange value
of the renminbi has remained relatively constant against the central bank's designated basket of
currencies, and it has depreciated against the dollar at a more gradual pace. Capital outflows,
while still significant, have moderated.
In Europe, the recovery has proven to be increasingly resilient. Monetary policy has continued to
provide crucial support. As a result, several challenges-including referendums in the United
Kingdom and Italy and liquidity and capital stresses faced by German and Italian banks-have so
far been navigated without significant damage to growth, financial stability, or inflation
expectations. Fiscal policy has ceased being a drag on demand growth and, in some cases, has
turned moderately expansionary. Overall euro-area GDP increased at an annual rate of 1-3/4
percent last year, sufficiently in excess of potential output growth to bring the unemployment rate
down nearly 1 percentage point. Despite some instances of heightened volatility, financial
markets have functioned reasonably well, and risk spreads have stayed contained, although
uncertainty about upcoming elections has likely led to some increase in French and Italian
sovereign spreads in recent months. Fears of disinflation also appear to have abated: Measures
of inflation compensation based on 5-to-10-year-ahead inflation swaps, which fell to 1-1/4
percent in the middle of last year, have recently moved up to 1-3/4 percent.
Activity in Japan has also picked up recently, with GDP increasing 1-1/2 percent last year-
noticeably above the estimated rate of potential growth-and the unemployment rate declining
1/4 percentage point to 3 percent, as monetary policy has remained supportive.
Of course, concerns regarding the medium to longer run remain. In China, the price of near-term
stability has been an increase in leverage, particularly in the corporate sector. China's overall
debt-GDP ratio is elevated for an emerging market economy, especially considering that Chinese
growth is likely to slow noticeably in coming years. In Japan, core consumer price inflation is
close to zero-well below the central bank's 2 percent target-and scope for additional monetary
policy accommodation is limited, leaving the economy vulnerable to adverse demand shocks. In
the euro area, growth and inflation may remain low for some time, which could pose challenges
for banks with low capital or high amounts of nonperforming loans and for highly-indebted
sovereigns. Political events in Europe also raise some uncertainty. Going forward, it will be
important to continue to monitor these and other foreign developments carefully.
Here at home, the economy is at a transition. The past few months have seen continued
progress in the labor market. Monthly gains in payroll employment have maintained a pace
sufficient to continue eroding labor market slack, and wage growth appears to be moving higher
on balance. Compensation per hour in the business sector, the most comprehensive measure of
wages, increased at a 3 percent pace the past two years, noticeably above the pace earlier in the
recovery.
We appear to be closing in on full employment. The unemployment rate-after remaining
relatively flat from the third quarter of 2015 to the third quarter of 2016-fell 1/4 percentage point
last quarter to 4-3/4 percent. In addition, the labor force participation rate has been about flat, on
net, over the past 2-1/2 years, which indicates considerable ongoing cyclical improvement, given
the declining demographic trend. Even so, there may be some room for further improvement.
The prime-age employment-to-population ratio remains depressed relative to pre-crisis levels;
the share of employees working part time who would prefer full-time work remains elevated; and
some measures of wage growth, such as the employment cost index, have increased relatively
little in recent years.
Most recently, we are also seeing welcome signs of progress on the second leg of our dual
mandate after a protracted period of shortfalls from the FOMC target of 2 percent inflation.
Recent months have seen a step-up in longer-run inflation compensation, which had dropped to
worrisomely low levels last year raising concerns about a softening of inflation expectations to
the downside. Both market- and some survey-based measures of inflation expectations remain
somewhat low, but there has been some movement in the right direction in the past few months.
Inflation has moved up lately as the effect of past increases in the dollar and declines in energy
prices have faded. The 12-month change in headline personal consumption expenditures (PCE)
prices was 1.9 percent in January, although this partly reflects a temporary boost from energy
prices. Core PCE inflation-which strips out volatile food and energy prices and is a good gauge
of future inflation-has also increased. At 1.7 percent in January, the 12-month change is 0.1
percentage point higher than a year ago. Still, core inflation has been below our 2 percent target
for almost all of the past eight years, and further progress is necessary to reach and sustain our
symmetric inflation goal.
Recent indicators of aggregate spending suggest we will continue to edge closer to our goals in
the months ahead. Consumption growth has been encouraging, supported by continued job
gains, rising wealth, and greater confidence. Business investment changed little the past two
years, but there are currently signs of renewed growth. The contrast with the situation a year ago
is sharp. Then, risk spreads on corporate bonds had risen noticeably-often a precursor to
downturns-measures of business sentiment were relatively depressed, and corporate profits
had declined over 10 percent. In recent quarters, the environment has become more favorable.
Risk spreads have moved back down to more normal levels, business sentiment has
rebounded, economic profits look to have turned up, and new orders for capital goods are
moving higher. The partial rebound in oil prices has also given a boost to drilling activity.
However, some crosscurrents could weigh on aggregate demand this year. The recent
increases in longer-term interest rates could restrain housing activity as well as other
interestsensitive areas of demand, and some further pickup in the dollar could weigh on net exports and
business investment.
Recent months have seen an increase in the upside risks to domestic demand. Sentiment has
increased along with equity prices, which are up around 10 percent since October. Increased
optimism could lead to faster growth in consumption and business investment, although the
spending data, thus far, do not suggest a noticeable acceleration. Some of the increase in
sentiment and changes in asset prices could be tied to expectations of more expansive fiscal
policy, another upside risk. In addition, the progress that we have made over the past year, with
the economy closer to meeting full employment and inflation objectives, has contributed to the
favorable shift in the balance of risks. The increase in upside risks to domestic demand and the
diminution of foreign risks together suggest that risks to the outlook are more balanced today
than they had been for the preceding two years.
Nonetheless, the neutral real rate of interest-or the level of the real federal funds rate that is
consistent with output growing close to its potential rate with full employment and stable inflation
-is expected to remain low both in the near term and in the longer run, and inflation is only
slowly recovering from a protracted period of low levels. The nominal neutral interest rate-which
adjusts the real neutral rate for the level of inflation-is likely to remain below its historical
average even once it reaches its new longer-run normal level. The lower rate environment
means there will be less room to cut the federal funds rate, so that if the economy experiences
adverse shocks similar in severity and frequency to those in the past the likelihood of returning to
and operating near the effective lower bound will remain elevated relative to historical experience.
Prudent risk management suggests that policy should take into account the asymmetry in risks
posed by the greater likelihood of the economy being at the effective lower bound, where
conventional policy is constrained.
What about the Balance Sheet?
Given the progress we have seen and the positive momentum in the incoming data, continued
gradual removal of accommodation is likely to be appropriate. But unlike in previous tightening
cycles, the Federal Open Market Committee currently has two tools to remove accommodation:
the balance sheet as well as the federal funds rate.
In December 2015, the Committee indicated that it would continue to reinvest principal payments
1
until normalization of the level of the federal funds rate is "well under way." The decision to rely
solely on the federal funds rate to remove accommodation initially until normalization is well
2
under way serves an important purpose, in my view. With asymmetry in the scope for
conventional monetary policy to respond to shocks, there is a benefit to enabling the federal
funds rate to rise more quickly than would be possible with a shrinking balance sheet and sooner
3
reach a level that allows for significant reductions if economic conditions deteriorate.
Even so, recognizing that the median of the Committee projections places the long-run value of
the federal funds rate around 3 percent-a very low level by historical standards-some could
judge normalization to be well under way before too long. Thus, monetary policy too may be
approaching a transition.
Once the short-term rate is comfortably distant from its effective lower bound, there are broadly
two types of policy strategies that could be contemplated. Many central banks around the world
may contemplate similar choices in the coming years, while the Bank of Japan has already
4
grappled with these issues in the past. One type of "complementarity" strategy might actively
deploy the balance sheet as an independent second tool, complementary to the short-term rate.
Under this strategy, both tools would be actively used to help achieve the Committee's goals.
This strategy would seek to take advantage of the ways in which the balance sheet might affect
certain aspects of the economy or financial markets differently than the short-term rate. Any
differences in effects might derive from the fact that the balance sheet more directly, though not
necessarily more precisely, affects term premiums on longer-term securities, while the
shortterm rate more directly affects money-market rates.
Although it may be tempting, in theory, to operate with the balance sheet as a complementary,
additional tool to the federal funds rate, we have virtually no experience with how such an
approach would work in practice away from the effective lower bound. For that reason, one might
instead prefer a "subordination" strategy that would prioritize the federal funds rate as the sole
active tool away from the effective lower bound, effectively subordinating the balance sheet.
Once federal funds normalization meets the test of being well under way, triggering an end to the
current reinvestment policy, the balance sheet would be set on autopilot, shrinking in a gradual,
predictable way until a "new normal" has been reached, and then increasing in line with trend
5
increases in the demand for currency thereafter. Under this strategy, the balance sheet might
be used as an active tool only if adverse shocks push the economy back to the effective lower
bound.
The case for the subordination strategy is straightforward and compelling. This strategy
recognizes that the two policy tools are broadly similar in the ways they affect the economy by
indirectly changing the level of interest rates used to finance purchases by households and
businesses. These interest rate changes also have effects on asset prices, and thereby on
household wealth, as well as on the exchange value of the dollar and, thereby, on net exports and
6
core import prices. However, relative to balance sheet policies, the influence of the short-term
rate is far better understood and extensively tested: There have been several decades and many
business cycles over which to measure and analyze how the federal funds rate affects financial
markets and real activity. In contrast, experience using the balance sheet as an active tool has
been very limited and largely confined to a highly unusual period around the Global Financial
Crisis, when short-term interest rates were constrained by the zero lower bound. Predictability,
parsimony, precision, and clarity of communications all would seem to argue in favor of focusing
policy on a single active tool that is most familiar. In short, it makes sense to focus policy on the
tool whose effects are better understood by both policymakers and the public in circumstances
where the tools are largely substitutes for one another.
Even with this subordination strategy, however, there may be limited circumstances in which the
balance sheet might be employed in a manner that is supportive of the short-term rate. Most
obviously, during the period when the balance sheet is running down, if the economy encounters
adverse shocks, it may be appropriate to commence the reinvestment of principal payments
again in order to preserve conventional policy space if the federal funds rate were to drop below
some threshold level, perhaps similar to the "well under way" threshold.
More broadly, although the two tools can achieve roughly similar effects, they are different, and
we cannot rule out that there may be special circumstances in which these differences may be
particularly valuable. In particular, these differences may be an important consideration in
circumstances when the transmission of changes in the short-term rate to long-term rates and
other financial market variables and the real economy is impeded. In addition to directly affecting
longer-term interest rates, changes to the balance sheet could serve to reinforce policy
communication associated with the short-term rate. Some observers believe that such signaling
was an important contributor to the effect of the balance sheet on the economy during and after
7
the Global Financial Crisis. Thus, the subordination strategy will likely be appropriate in most
circumstances, but we cannot completely rule out special circumstances in which the
complementary use of both tools may prove compelling.
Assuming that a subordination strategy is adopted, and the balance sheet is set to shrink
passively and predictably once reinvestment ceases or is phased out, there is some uncertainty
around the size of the balance sheet when it returns to normal, which the Committee has
described as "no larger than necessary for the efficient and effective implementation of monetary
policy."
There are good reasons to expect a normalized balance sheet to be considerably smaller than
its current size but larger than its pre-crisis level. Most obviously, trend growth in the demand for
currency gradually pushes up the size of the balance sheet over time, but there are also other
reasons to expect the post-crisis new normal to be larger than pre-crisis levels. The structural
demand for reserves may be considerably larger now than prior to the financial crisis because of
a number of changes, including new regulations that favor safe liquid assets and changes in
8
financial institutions' attitudes toward risk. If the demand curve for reserve balances has shifted
out, then a greater supply of reserves will be needed to attain a given interest rate target.
Moreover, the supply of reserves will need to be set far enough above the structural level of
demand to accommodate unexpected shocks to the demand and supply of reserves. To
accomplish this, the Committee could choose to implement policy by adjusting the supply of
reserves to offset such shocks. Or, the Committee could decide to maintain the current floor
system, in which a buffer of reserves, sufficient to accommodate any sizable shocks to reserves
demand and supply, is maintained, thereby obviating the need for high-frequency adjustments to
the supply of reserves. The Committee's normalization principles suggest that any buffer would
9
be the minimum amount needed to efficiently and effectively implement policy.
Because of changes in structural and short-term factors since the crisis, it is difficult to know
with any precision how low reserves can be allowed to drop while still maintaining effective
interest rate control. Thus, as the balance sheet gradually declines, it will be important to
carefully monitor money markets for indications that any further reduction in the supply of
reserves will begin to put upward pressure on money market rates. At that point, the amount of
reserves will likely be close to the minimum amount necessary to satisfy demand at the target
10
rate.
Conclusion
To conclude, recent developments suggest that the macro economy may be at a transition. With
full employment within reach, signs of progress on our inflation mandate, and a favorable shift in
the balance of risks at home and abroad, it will likely be appropriate for the Committee to
continue gradually removing monetary accommodation. As the federal funds rate continues to
move higher toward its expected longer-run level, a transition in balance sheet policy will also be
warranted. These transitions in the economy and monetary policy are positive reflections of the
fact that the economy is gradually drawing closer to our policy goals. How the Committee should
adjust the size and composition of the balance sheet to accomplish its goals and what level the
balance sheet should be in normal times are important subjects that I look forward to discussing
with my colleagues.

Some experts have made financial stability arguments in favor of maintaining a level of reserves that is
somewhat larger than needed for monetary control alone. In the past, the demand for safe short-term assets
has sometimes been met by an increased supply of private-sector short-term debt, which has been associated
with increased leverage and maturity and liquidity transformation. Some argue that a greater supply of safe
short-term public debt could help prevent these potentially destabilizing developments from occurring. See
