Monetary Policy
and Exchange-
Rate Trends
Mr. Balles asks: W/uit lessons can we learn from a review of the past
decade's experience with exchange rates? The most important lesson, he
says, is that we cannot have a strong and stable dollar without a steady,
credible anti-inflation policy. Second, the dollar (and financial markets
generally) react increasingly to expected future policies. And third, our new
policy of targeting bank reserves in an effort to achieve closer control of
money growth may mean somewhat more volatility in short-term interest
rates, and hence more short-term fluctuations in the dollar, than we used
to encounter. But in his view, the costs of high and variable inflation are
likely to be much greater than the costs of some increase in the short-run
volatility of the dollar.

Monetary Policy and
Exchange-Rate Trends
I'm glad to have this chance to participate in the work of the Institute
on International Banking, and to share with you my thoughts about the
complex relationships of monetary policy and exchange rates. The world
has changed tremendously in the past decade, and international banking
has been one of the main arenas of change. I hope that whatever you learn
from these discussions will help you deal more successfully with the prob
lems created by this changing world.
Those who buy and sell foreign exchange have not had an easy task in
recent years. The dollar has strengthened over the past year, but its value
is substantially lower than it was four years ago, and it has experienced
some painfully sharp and sudden fluctuations during that period. U.S.
policy-makers consequently have become concerned about the impact of
these changes on the nation's economic policy. Clearly, it is in the U.S.
interest to preserve confidence in the dollar, which plays such a critical
role in international trade and finance. Equally clearly, policy-makers
want to avoid foreign-exchange crises, which might put downward pressure
on the dollar and thereby add to domestic inflationary pressures.
Still, I believe that policy-makers have learned some valuable lessons
from the past decade’s experience with floating exchange rates. Certainly
we have learned that the course of the dollar depends critically upon the
policies toward inflation followed here and abroad. Today I would like to
explain how monetary policy affects exchange rates, and summarize the
lessons policy-makers have learned from their experiences.
Perspective on the Issue
Before I discuss in detail the relationship between monetary policy and
exchange rates, 1 would like to provide some background perspective on
the issue. The exchange rate can be considered as a price, much like the
price of any commodity. It reflects how many U.S. dollars it takes to pur
chase a foreign currency. For example, at the present time one U.S. dollar
will buy approximately 200 Japanese yen, two Deutschemark, or 1,000
Italian lira. As with any price, the exchange rate is determined by the
forces of supply and demand. The international supply of dollars is deter
mined by U.S. residents, who wish to purchase foreign goods and services
and financial assets. The international demand for dollars comes from
foreign residents who wish to purchase U.S. goods and services and
financial assets.

Thus, monetary policy can affect the exchange rate by affecting the
international supply and demand for dollars. We generally find it conve
nient to divide the international supply and demand for dollars into a trade
account, to reflect the purchases and sales of goods and services, and a
capital account, to reflect the purchases and sales of financial assets.
Under the regime of flexible exchange rates we’ve had since 1973, the
trade and capital accounts together have determined the value of the dollar.
But in the long-run, monetary policy influences the dollar primarily through
the trade account, by determining the level of U.S. prices relative to abroad.
The dollar, of course, must ultimately adjust to this level to preserve the
competitiveness of U.S. goods in world markets — this is simply the well-
known “purchasing power parity” explanation of exchange rates.
In the short-run, monetary policy acts primarily through the capital
accounts to affect the dollar — first, by influencing investors’ expectations
about future inflation and, second, by changing real interest rates (i.e.,
interest rates adjusted for inflation). When monetary-policy shifts or other
factors change investors’ expectations about inflation, they naturally move
out of the inflating currency to avoid a loss of purchasing power, which
immediately pushes its value down on the foreign exchanges. In this way,
exchange rates tend to anticipate changes in the long-run value of the dollar
as determined by “purchasing power parity.” In addition, monetary policy
affects the dollar in the short-run by temporarily changing the level of
interest rates relative to anticipated inflation, that is, by changing real
interest rates. Rising real interest rates attract investors to the dollar, caus
ing its value to rise, while falling real interest rates push the dollar down.
With this brief overview, let me now describe in more detail the factors
which I believe have linked monetary policy and exchange rates over the
last several years.
Long-Run Factors
In my view, our experience with floating exchange rates since 1973
demonstrates conclusively that the long-term trend in the dollar — its direc
tion over a year or more — is primarily a reflection of the course of U.S.
inflation relative to inflation abroad. This of course means that the long
term trend in the dollar is critically dependent upon the monetary and fiscal
policies we pursue here in the U.S., as well as those taken abroad.
It's easy to see why inflation here and abroad should determine the
dollar’s long-term course. When U.S. prices rise faster than foreign prices,
our exports become more expensive than those of our competitors, while
goods imported into the U.S. become cheaper than those produced in our
own factories, by our own workers. Clearly the dollar will have to fall to
restore our competitiveness and to keep our trade accounts in balance.

You can see this relation between inflation and exchange-rate trends most
clearly if you compare the U.S. with individual foreign nations, as in Charts
1 and 2, with their comparisons of the U.S. with Germany and Italy. As you
can see from the black line on the first chart, American inflation has been
persistently higher than that of Germany — i.e., the ratio of German to U.S.
wholesale prices has fallen. As expected, this trend has been reflected in a
falling value of the dollar against the mark, as shown by the colored line.
Conversely, Chart 2 shows that Italy's inflation has been higher than ours
since 1974 — i.e., the ratio of Italian to U.S. wholesale prices has risen —
and the dollar is now higher against the lira than it was then.
As you might expect — and as the third chart confirms — trends in the
average value of the dollar against the major foreign currencies have also
followed the course of U.S. inflation relative to the average abroad. For
example, it’s no coincidence that the dollar rose during 1975 and 1976, at
the same time that the prices of U.S. goods were falling relative to abroad.
Nor is it coincidence that when, beginning in early 1977, U.S. inflation
accelerated faster than in other countries, the dollar fell back.

Money Growth and Exchange Rates
The long-run relationship between inflation rates and exchange rates sug
gests that U.S. policies toward inflation play a key role in determining the
strength and stability of the U.S. dollar. Furthermore, inflation in the long-
run is mainly the result of overly rapid money growth. This is not to deny
that a variety of factors other than money, such as food and energy costs
and mortgage rates, can temporarily affect inflation in the short-run. But
the experience of the last twenty years demonstrates conclusively that when
a country raises its money growth rate excessively, its inflation rate can be
expected to rise over time. This is simply a reflection of the “law of supply
and demand,” which applies no less to money than to any other commodity.
Raising the supply of money relative to the supplies of goods will inevitably
lead to inflation.
In 1974 and 1975, U.S. money growth slowed substantially. This helped
lead to a slowing of U.S. inflation relative to abroad, and hence to a rise in
the dollar’s value. Then, when money growth began to accelerate beginning
in late 1976, the dollar fell and U.S. inflation later surged. This pattern

suggests that whether the dollar rises or falls in coming years will depend
primarily on relative inflation rates in this country and abroad — which in
turn will reflect relative money-growth trends here and abroad.
Short-Run Factors . . .
While it is clear that the long-run path of the dollar is determined by
inflation trends, it has also become evident that it can depart substantially
from this “purchasing power parity” path in the short-run. However, only
fairly recently have we begun to appreciate how monetary policy affects
the dollar in the short run by changing flows through our capital account.
The capital account’s influence on exchange rates simply reflects the ease
with which funds now move among the major industrial nations in response
to profit opportunities. As a result, the demand for dollars and other major
currencies has come to be dominated in the short-run by investors’ actions.
Now, investors in dollars must reckon with the possibility that the pur
chasing power of their assets will fall if U.S. inflation rises in the future.

depreciation against the currencies of fifteen trading partners. The ratio of foreign WPI to U.S. WPI was
constructed from (trade-weighted) wholesale price indices of six major industrial nations. Data are
quarterly averages from 1974.1 to 1980.4.

Naturally, those investors will try to predict future inflation when deciding
whether to buy or sell dollars now. This forward-looking character of the
foreign-exchange markets means that inflation anticipated for the future
affects the dollar immediately by influencing capital flows. This explains
why the exchange value of the dollar seems at times to run ahead of, i.e.
anticipate, inflation trends. For example, you can see from Chart 3 that the
dollar began to rise early in 1975, even before the early 1976 decline in the
U.S. inflation rate below the average abroad — i.e., rise in the ratio of
foreign to U.S. prices. This dollar strengthening continued until mid-1977,
when a major reversal occurred and the dollar declined sharply, well ahead
of the relative rise in the U.S. inflation rate — i.e., decline in the ratio of
foreign to U.S. prices. In effect, the financial markets were anticipating a
change in purchasing power parity, and the forward-looking foreign-
exchange market adjusted to it rather quickly.
Some of you may recall that U.S. monetary policy was relatively tight in
early 1975. Investors, of course, knew that this slower growth in the U.S.
money supply would, in time, reduce the U.S. inflation rate. This increased
the incentive to purchase dollar assets at the expense of foreign assets, and
led to a large capital inflow and the immediate appreciation of the dollar you
can see in Chart 3. U.S. monetary policy eased in the second half of 1975
and into 1976, but not as substantially as monetary policy in other countries.
This led to a continued strengthening in the dollar, which lasted until the^^
early months of 1977. The introduction of a substantially more expan-^^
sionary monetary policy in early 1977 was the key factor contributing to the
subsequent decline in the exchange value of the dollar, which lasted until the
end of 1978. The consequences for inflation took longer to show up. We are
even now living with those effects.
In general, financial-market reactions to changes in monetary policy have
led to quick adjustments in foreign-exchange markets. These financial-
market responses can be thought of as attempts to anticipate what pur
chasing power parity will be. As a result, the exchange rate tends to move
ahead of the movement in national price levels. That has been one of the
most important elements in accounting for the movements in exchange rates
over the last five years.
. . . And Interest Rates
Finally, officials have always known that monetary and fiscal policies
can affect exchange rates by their impact on interest rates. The reason, of
course, is that the interest rates paid in U.S. financial markets are a major
factor determining whether investors will purchase either dollar assets, or
assets,denominated in other currencies.
However, our experience since 1973 has also shown that the relation
between interest rates and the dollar is not as simple as we once thought.

Conventional wisdom says that, when U.S. interest rates rise above those
abroad, the dollar also rises; when our interest rates decline, the dollar is
supposed to decline with them. Certainly this conventional wisdom has
been accurate after October 1979, as you can see from Chart 4. As short
term interest rates here rose above the average abroad between October
1979 and March 1980, the dollar rose with them. When our interest rates
fell back during the second quarter of last year, the dollar declined as well.
Equally clearly, though, this conventional wisdom did not work nearly as
well prior to October 1979. Indeed, rising U.S. interest rates were more
often associated with a falling dollar (and vice-versa) — as you can see
from Chart 4 for 1977 and 1978.
The divergence in the effects of interest rates on exchange rates can be
explained by the existence of two very different factors that can cause
interest rates to rise. First, they can rise because of a rise in inflation expec-

The index of average value of the dollar is a trade-weighted average of the dollar’s appreciation or
depreciation against the currencies of fifteen trading partners. The interest-rate differential is the differ

Euro-currency rates for six major industrial countries. Both data series are monthly from January 1976
through January 1981.

tations, as lenders demand a higher yield to compensate for the anticipated
loss of purchasing power. Second, interest rates can rise because the so-
called real interest rate has gone up. This occurs when market rates rise
relative to the anticipated inflation rate; by definition this means a rise in
the real interest rate, which is simply the difference between the market rate
and expected inflation. A rise in real interest rates is normally a temporary
phenomenon, which results from unusual demand for credit relative to its
available supply.
There is no precise way to separate the expected inflation and the real
interest rate components of the observed market interest rate. In Chart 5 an
attempt is made to approximate the two influences for the 3-month Treasury
bill rate. It shows the actual inflation rate of the last 12 months as a measure
of the expected rate of inflation. The real interest rate is then the difference
between the actual interest rate and this expected inflation rate.
While either of these two factors can cause U.S. interest rates to rise,
they have very different impacts on the exchange rate. When U.S. interest

rates increase simply because inflation is expected to increase, the dollar
is likely to fall on the foreign exchanges. In this case, investors move capital
out of the U.S. because they know that higher inflation must ultimately
lead to a falling dollar. On the other hand, when U.S. real interest rates
increase — as they have recently — then investments in the dollar become
more attractive, capital flows into the U.S., and the dollar rises on the
foreign exchanges. Thus, the conventional wisdom that the dollar rises
when U.S. interest rates rise is correct only when the interest-rate increase
is due to a rise in real interest rates — that is, when the interest-rate hike
more than compensates for the rise in the expected inflation rate.
On this basis, we can more easily see why the conventional wisdom about
interest rates and the dollar worked after October 1979 but not before, as
shown in Chart 4. And as we can also see (Chart 5), U.S. interest rates in
creased during 1977 and 1978 only in proportion to the rise in the U.S.
inflation rate — that is, the real interest rate remained virtually unchanged.
Since, as can be seen from Chart 4, the 1977-78 rise in U.S. interest rates
relative to those abroad was strictly inflation-induced, it was associated
with a fall in the dollar. On the other hand, since October 1979, U.S. interest
rates have fluctuated unusually sharply relative to the underlying inflation
rate. This suggests that we've had much more variation in real interest rates
in the most recent period, causing interest rates and the dollar to move
• together more closely than in the past. In particular, the sharp rise in U.S.
interest rates between October 1979 and March 1980 shown in Chart 5
resulted largely from the Federal Reserve's tightening of credit in an effort
to slow money growth. This caused real interest rates to rise here, leading to
a sharp rise in the dollar. This pattern reversed beginning in March 1980,
when a reduction in credit demand due to slower real growth and the special
credit control program lowered interest rates well below the inflation rate,
bringing about a decline in the dollar. And we're now in another such cycle,
with our interest rates again above inflation, accounting substantially for
the strength of the dollar in recent months.
But why, you may ask, did real U.S. interest rates apparently fluctuate
more severely after October 1979 than before? Part of the reason, I believe,
lies with the new procedures to control money growth and inflation that
were adopted at that time. Prior to October 1979, the Federal Reserve
stabilized interest rates in the short-term. When credit-market demands
rose sharply, we frequently increased bank reserves rather than allowing
interest rates to rise. This policy had the effect of smoothing out fluctuations
in real interest rates substantially — but at the expense, we ultimately
found, of adequate control of money growth and inflation.
Since October 1979, we have allowed short-term interest rates to fluc
tuate more freely, placing more emphasis on controlling the quantity of

bank reserves than on tightly pegging their cost (the Federal funds rate).
Our experience with this new procedure certainly suggests that we will have
somewhat more short-term variability in real interest rates, and thus more
short-term volatility in the dollar, than we would have expected under the
old procedures. However, I believe we must still be very cautious in draw
ing conclusions from last year’s experience about future trends in interest
rates and exchange rates. The reason is that other factors besides the Fed’s
new procedures — such as the credit controls imposed in March 1980 and
removed several months later — have contributed to interest-rate fluctua
tions.
Conclusion — Lessons Learned
What lessons can we learn from our review of the past decade’s experi
ence? The most important lesson is that we cannot have a strong and stable
dollar without a steady, credible anti-inflation policy. Countries such as
Germany and Japan have been much more successful than the U.S. in fight
ing inflation, and the strength of their currencies against the dollar reflected
this fact until the U.S. adopted more vigorous anti-inflation measures.
Second, we’ve learned that the dollar, and financial markets generally,
react increasingly to expected future policies. The day is long past (if it ever
was) when the dollar reacted only to current policies and to officials’ pro
nouncements about what they would be in the future. Indeed, we’ve becomei
painfully aware that the penalty for erratic policies, or policies that lack
credibility, can be quite severe in terms of instability in foreign-exchange
markets. In a sense, the exchange markets provide a mirror in which policy
makers can see how their policies actually appear to the public at home and
abroad. Sometimes that mirror has provided an unflattering picture in
recent years.
We’ve also learned a third lesson — that our new policy of targeting bank
reserves in an effort to achieve closer control of money growth may mean
somewhat more volatility in short-term interest rates, and hence more
short-term fluctuations in the dollar, than we used to encounter. But in my
view, the record of the past several years clearly indicates that the costs
of high and variable inflation are likely to be much greater than the costs of
some increase in the short-run volatility of the dollar. Businesses and
individuals engaged in international trade and investment normally must
take a long view regarding where the dollar will be in a year’s time, or in
several years’ time. Over this time horizon, the most critical factor affecting
the dollar is plainly its long-run trend, which is determined by inflation
trends in the U.S. and abroad. Consequently, the benefits of reducing
our inflation — such as we hope to achieve with our new procedures —
should far outweigh the inconvenience of some increased short-term vola
tility of the dollar.

In this respect, the dollar can be likened to a ship, and foreign-exchange
market participants to its passengers. The passengers can always expect
some rocking from the waves and from temporary squalls. But they will
plainly be better off if their ship has a rudder and a steady hand at the helm.
Stable policy measures provide the surest rudder for the dollar. And the
task of policymakers over the next several years is to steer a steady course,
for the sake of the dollar and the U.S. economy as a whole.
