Synching, Not Sinking, the Markets
William Poole*
President, Federal Reserve Bank of St. Louis
Meeting of the Philadelphia Council for Business Economics
held at the Federal Reserve Bank of Philadelphia
Philadelphia
Aug. 6, 1999
*I appreciate comments provided by my colleagues at the Federal
Reserve Bank of St. Louis. I take full credit for errors. The views
expressed are mine and do not necessarily reflect official positions
of the Federal Reserve System.
I have long been fascinated with the study of market
responses to policy actions. Prices in speculative markets respond
sensitively to events, including policy actions and hints about
policy actions, of all kinds. The markets I am referring to include
the equity, bond, commodity and foreign exchange markets. Policy
actions include those by the Federal Reserve, the executive branch
of the federal government, the Congress, courts and many other governmental
bodies. Although today I will discuss this topic in the context
of Federal Reserve policy actions, I mention the wide array of markets
and governmental units to emphasize that the subject is a very broad
one indeed.
My interest in market responses to policy actions has only been
heightened by my still-new job as St. Louis Fed president. I have
found myself puzzling over market reactions to Fed policy and speculation
about Fed policy. I am certainly acutely aware of the fact that
what Fed officials say can move markets. The issue for me is how
to understand market responses at a deeper level, because I think
improved understanding will strengthen monetary policy and reduce
market volatility.
My question is this: What would we expect to observe in speculative
markets if monetary policy were working "perfectly"? I
do not mean "perfectly" in some utopian sense, but within
the context of the world of incomplete information in which we actually
live. We know that policy problems may arise when the central bank
and the markets have different information sets, or have different
perceptions about the state of the economy or the direction of policy.
My concept of policy "perfection" is that the markets
and the central bank have the same information set, incomplete
though it may be. Information is incomplete because the future is
uncertain and the discipline of economics is unsure about many important
relationships.
I'm deliberately using the word "perfect" rather than
the word "optimal" because I want to avoid the implication
that the subject at hand is an optimal control issue, which would
involve such matters as a possible trade-off between employment
stability and price stability. I am assuming that society has somehow
made its choices according to the objectives of monetary policy
and how they are to be pursued within the constraints of how the
economy works. The terminology is a bit awkward; information is
inherently imperfect, but my topic concerns differences in information
held by the central bank and the markets. By policy "perfection,"
I mean that the differences in information have disappeared-both
the central bank and markets have the same imperfect set of information.
I'll keep "perfection" in quotation marks to help make
clear that the issue is the equality of imperfect information between
the central bank and the markets.
The assumption that monetary policy is "perfect" implies
certain things about how markets should behave. I will concentrate
on the behavior of financial markets, and will take as givens the
policy goals so I can concentrate on the "perfection"
of information between the markets and the central bank. This topic
is a large one; my purpose is to introduce my model, explain how
this model can help us understand how policy has evolved, suggest
ways in which departures from "perfection" indicate problems
with my underlying model and ways to improve policy. I'll only be
able to touch upon a few of these areas.
Here are the key questions my analysis addresses: Under a "perfect"
monetary policy, would we observe large market responses to policy
actions? And, would we observe large market responses to innovations,
or surprises, in economic data? I will argue that under a "perfect"
monetary policy, we should not expect to observe any market
reactions to Fed policy actions. Every Fed policy action should
be completely anticipated by the time it occurs, and therefore should
be a nonevent in the markets.
I'll proceed by first listing a few examples of dramatic policy
changes that did have major effects on market prices. Then I'll
briefly discuss the efficient markets model that serves as the baseline
explanation of price determination in speculative markets. Because
my topic concerns the interactions of the markets and the policymakers,
I'll next discuss Federal Reserve objectives and policy implementation.
Putting the market and Fed policy together, my claim is that policy
"perfection" requires the Fed and the markets to react
the same way to arriving information. In this case, the market and
the Fed are in synch; the market anticipates Fed policy actions
and is not surprised by them. Large changes in market prices to
policy actions obviously indicate market surprises. In such cases,
policy changes can sink the markets, or send them into orbit.
Before proceeding, I want to emphasize that the views I express
here are mine and do not necessarily reflect official positions
of the Federal Reserve System. I thank my colleagues at the Federal
Reserve Bank of St. Louis for their comments, while retaining full
credit for errors.
Market Reactions to Policy Actions
Let's start by examining a few dramatic examples of policy changes
that reflected Federal Reserve actions or had possible implications
for future Federal Reserve actions:
- Sunday, August 15, 1971. President Nixon closed the gold window
and announced comprehensive wage and price controls. The following
day, the 20-year Treasury bond yield fell by 18 basis points and
the Dow Jones Industrials rose by 3.8 percent.
- Saturday, October 6, 1979. The Federal Reserve introduced a
dramatic set of new policies. When the markets reopened the following
Tuesday (Monday was the Columbus Day holiday), the 30-year Treasury
bond yield rose by 25 basis points, and the Dow Jones Industrials
sank by 4.5 percent.
- Sunday, September 22, 1985. The G5 countries announced the Plaza
Agreement, which called for these countries to pursue policies
to depreciate the foreign exchange value of the U.S. dollar. The
trade-weighted dollar index fell by 3.5 percent the next day,
the 30-year Treasury bond yield rose 6 basis points, and the Dow
Industrials rose 1.4 percent.
These three examples reflect dramatic policy changes. I could offer
hundreds of other smaller and more routine examples. I have refrained
from listing examples of market responses to nonpolicy information,
such as the employment report that arrives on the first Friday of
every month, but I am sure that everyone here is familiar-perhaps
all too familiar-with such market responses. Markets react to data
releases in part because of the belief that the central bank will
respond to the information.
What do we make of these market reactions to both policy actions
and data releases? From a policy perspective, are these market responses
simply an unavoidable side effect of policy actions? Should the
monetary authorities attempt to avoid large market reactions, or
are the market reactions an essential part of the process by which
monetary policy effects are transmitted to the economy?
The Efficient Markets Paradigm
The efficient markets paradigm surely has to be the starting point
in understanding speculative markets. According to this view, speculative
markets respond efficiently as market participants assess all relevant
information-absolutely everything that might influence market prices-and
bid market prices up or down accordingly. Given that investors bid
current prices to levels at which risk-adjusted expected rates of
return are equalized across various investment alternatives, each
new piece of information may move market prices. The efficient markets
model is not perfect, but it certainly goes far in explaining the
behavior of speculative prices.
So, markets respond to the flow of all sorts of information, including
that from the central bank. Federal Reserve policy actions, and
statements by Federal Reserve officials-especially the chairman-affect
market expectations about the future and, therefore, current market
prices.
The information that matters, of course, is new information. Everything
predictable has already been bid into market prices; only the reports
coming across the wires that change the probabilities of future
outcomes affect current market prices. This point is well understood
by most market participants and most of the financial press.
Monetary Policy Actions
Now I want to discuss the interactions of speculative markets with
monetary policy actions.
Market participants are trying to forecast the future, and so they
are naturally interested in what the Fed is trying to do. Let me
make the assumption-which I think is accurate, but will not argue
here-that the goal of the Federal Reserve is to keep the rate of
inflation low and steady, a goal that I'll call "price stability."
Also, insofar as possible given the price stability goal, the Fed
wants its policy actions to contribute to the stability of employment
and output. I believe that price stability will, if anything, yield
lower average unemployment than will prevail at higher inflation.
Price stability will contribute to maximum sustainable economic
growth.
So, the Fed's primary goal is price stability and its secondary
goal is stability of output and employment to the extent possible.
However, my argument does not depend on the specification of the
monetary policy goals-substitute your own if you do not like my
formulation. Of course, the markets must assess not only the Fed's
goals, but also its skill in achieving those goals. I also take
as given the policy procedures the Fed uses to reach its goals.
The point is that the Fed's policy goals and procedures are key
pieces of information to the markets because this knowledge helps
market participants predict how the Fed will respond to new information.
How would we expect markets to behave if Federal Reserve policy
were "perfect?" If policy were "perfect," we
would certainly not expect the federal funds rate-the Fed's
short-run policy instrument-to remain forever constant at an unchanged
level. The fed funds rate would have to be higher sometimes and
lower sometimes to be consistent with the policy objectives. How
would the Fed decide when and by how much to change the federal
funds rate? Well, as new information arrived, the Fed would process
that information to decide on adjustments of the federal funds rate.
FOMC members are constantly examining the flow of incoming information
on the state of the economy and working to decide what policy actions
may be necessary to keep the economy on the desired track.
Of course, FOMC members may have different interpretations of the
incoming flow of data and the appropriate policy responses. The
implications for policy of a particular event are rarely perfectly
clear. The fact is that economics provides tremendous guidance,
but does not provide calculations out to the second decimal place.
Indeed, sometimes even the appropriate direction of policy action
is unclear. Nevertheless, it is helpful to think about policy this
way: That there is in principle some correct policy response to
each piece of information that comes along, and that the aim of
the FOMC is to dial in that response at its next meeting. The appropriate
response, for example, may be to keep the funds rate steady. Indeed,
I am convinced that one of the greatest benefits a high degree of
market confidence in the Fed affords is the Fed's ability to sit
tight and wait until it's quite clear which Fed policy actions are
appropriate.
Now let's return to the market responses. The markets and the Fed
are both responding to the same flow of information. At this point,
let's assume that the markets and the Fed get the same information
at the same time-neither has an informational advantage. It is easy
to see the nature of the expectational equilibrium. The markets
and the Fed have a common response to new information. The
markets know the Fed's policy objectives and the policy adjustments
that are appropriate given each piece of new information. The FOMC
meets every six weeks, but by the time of each meeting, the markets
know full well what policy adjustment, if any, is necessary and
desirable. The Fed adjusts policy according to the market forecast,
and no one is surprised. Fed action is a nonevent in the markets.
The predictability of Fed policy actions under these conditions
is the central insight of the analysis. Given that the FOMC acts
as the market forecasts, the FOMC's actions are not themselves information
and therefore elicit no adjustment of market prices. Those adjustments
have already taken place during the period between FOMC meetings
as the markets respond to the steady flow of new information in
the form of the employment report, housing starts, productivity,
employment cost index, etc., etc., etc.
Synching Markets and Policy
This idealized picture of the markets and the Fed responding the
same way to the same data is, I believe, the model we should all
be striving to achieve. We want price stability precisely because
we believe that avoiding inflation surprises adds to the efficiency
of the market economy and promotes maximum sustainable economic
growth. We cannot hope or expect to avoid all surprises, for the
nature of our world is that the future is unpredictable. These unpredictable
events include natural disturbances, such as earthquakes and floods,
political disturbances at home and abroad, many changes in tastes
and technology, and so forth and so on. Markets respond efficiently
to these disturbances most of the time. Our aim is for monetary
policy to offset shocks, when possible, to prevent them from pushing
the economy away from price stability. Of course, we also want to
avoid introducing monetary policy disturbances per se that adversely
affect price stability.
The job of the central bank is to maintain a clear focus on price
stability and to convey that focus to the markets. The central bank
and the markets can then respond in identical fashion to the flow
of incoming information, reaching the same conclusions as to implications
of the information for monetary policy adjustments. In this model,
the markets are not taken by surprise by policy actions, for they
have already figured out what needs to be done.
I think this idealized picture takes us a long way toward understanding
how monetary policy and the markets should interact when
policy is on a successful track. In this environment, the Fed and
the markets are synched. With complete synchronization, the markets
and the Fed have a common understanding of the objectives of monetary
policy and a common interpretation of the significance of each piece
of incoming information.
Suppose the federal funds futures market does, in fact, accurately
forecast decisions at FOMC meetings. Is that an indication that
the Fed is simply following the markets, and not exercising its
proper leadership role? Obviously, I think not. Market prices that
anticipate what the FOMC is going to do are not only consistent
with policy "perfection," in the sense that I have been
discussing, but also actually necessary for policy "perfection."
Regularity and predictability are important policy goals. Market
success in anticipating FOMC actions indicates Fed success in designing
policies to achieve goals society accepts, and in conveying those
policies to the public. I put the point this way because no central
bank in a democratic country can long pursue goals not accepted
by the society at large. The markets and the Fed cannot converge
on a common understanding of the direction of monetary policy if
the Fed does not pursue its goals in a consistent fashion over time.
What do we make of cases in which Fed policy actions create large
market responses? Clearly, policymakers can sink the markets, or
send them into orbit, when a surprise policy action boosts market
prices. Changes in policy direction are not necessarily undesirable;
policy ought to change if it has drifted off course. That,
I believe, was the case with the 1979 change in Fed policy. What
is unfortunate about such a case, however, is that policy drifts
off course in the first place. Sinking, or orbiting, the markets
certainly can reflect some sort of policy failure, either because
an undesirable policy is being corrected, or because policy is taking
off in an unforeseen and undesirable direction. I believe that the
1971 policy turn toward comprehensive wage and price controls was
an example of policy taking a wrong turn. I include this case in
my list of examples because the introduction of wage and price controls
did have monetary policy implications; many observers thought the
controls would take care of inflation and permit monetary policy
both to be more expansionary and drive down unemployment.
Sinking may also reflect some sort of market error. I have deep
respect for market judgments, but do not believe that they are invariably
correct. Sometimes markets wake up to errors, and prices adjust
rapidly. Very little is known about this subject, but the 1987 stock
market crash is certainly an example of a market error. Either the
crash was an error, the market advance prior to the crash was an
error, or both were errors. No economic data or policy changes arrived
at the time of the crash to justify an adjustment that large.
In any event, the key point remains. A large market response to
a Fed policy action is evidence that the markets and the Fed are
not in synch. Either the market or the Fed, or both, must have been
operating on the basis of different information, which may include
different assessments of the significance of readily observable
data. The more complete the convergence of views between the market
and the Fed, the better the economy will work. Convergence reduces
market volatility and expectational errors, which can lead to resource
misallocation. Firms, for example, may make investments that prove
to be unprofitable because their expectations were wrong.
The Fed has not reached the point that its policy actions elicit
zero response in the markets. But let me offer a hypothesis, which
I have not yet investigated but hope to be able to. Everyone agrees
that, in recent years, economic outcomes-in terms of both inflation
and unemployment-have been better than in the past. My hypothesis
is that monetary policy has been more regular and predictable than
it used to be. This hypothesis can be tested by examining whether
Fed policy actions account for a smaller fraction of the variance
of interest rate changes in recent years than in the past. Put the
other way around, my hypothesis is that nonpolicy events, such as
data releases, account for a larger fraction of total interest rate
variance now than they did in the past.
My model of synching the markets and policy is incomplete in some
important respects. Two issues particularly concern me.
First, the pure version of the model requires that the Fed and
the markets have the same information about the economy. I think
that, relative to the markets, the Fed actually has superior information
in some cases and inferior information in other cases. What is clear
is that full synchronization with the markets requires that the
Fed pay careful attention to both collecting and conveying information.
Transparency and clarity are necessary ingredients for policy success.
Second, there are considerable differences in professional opinion
about how the economy works. The debates inside the Fed and outside
the Fed are similar. The markets and the Fed will never be completely
in synch because there will always be something for economists to
argue about, and the Fed and the markets will not necessarily come
to the same judgments. Still, it is important not to lose sight
of the fact that there is an enormous common base of understanding
between the Fed and the markets, and that this common base has a
lot to do with policy success.
Closing Comment
I'll close by re-emphasizing my main theme. When the markets and
the Fed are in synch, both will have a common reaction to incoming
data, and the markets will correctly anticipate Fed policy actions.
An environment in which markets correctly anticipate Fed actions
implies a situation in which Fed policy is widely understood, regular
and predictable. The fact that Fed policy actions sometimes take
the markets by surprise shows that we have not reached "perfection"
yet.
Still, it is important to recognize that the Fed has made tremendous
progress over the last 20 years or so in pursuing a consistent policy
designed to establish price stability as the norm for the economy.
The Fed and the markets are mostly in synch; surprises in the incoming
data-whether on prices, employment, GDP, activity in economies abroad,
and so forth-are surprises to both markets and the Fed and both
read the surprises pretty much the same way. If the market and Fed
readings become identical, we can expect that Fed policy adjustments
will convey no new information to the market, and therefore market
prices will not respond to them because they are fully anticipated.
I believe that a policy agenda designed to heighten the degree
to which the Fed and the markets are in synch is an ambitious and
worthy objective. We in the Fed need to work on two fronts, in my
opinion. One is the policy front itself, making sure that policy
actions are as appropriately timed and scaled as possible. The second
is on the disclosure front, making sure that knowledge inside and
outside the Fed converges to the maximum possible extent.
Progress on both fronts will require continuing research. It is
clear to me that new insights into the convergence, or lack thereof,
of information between markets and the Fed will play a central role
in this research. My insight today is completely consistent with-indeed
is implied by-rational expectations macro models. What I had not
done before in my own mind is relate these abstract models to the
daily ebb and flow of market reactions to new information. The conclusion
I have been discussing-that, with full convergence of information,
Fed policy actions will not affect market prices because the market
has already predicted them-initially surprised me. But the more
I think about the matter, the more compelling the conclusion is.
I hope you agree.
