East Asia’s Foreign Exchange Rate Policies
Summary
Financial authorities in East Asia have adopted a variety of foreign exchange rate
policies,
ranging from Hong Kong’s currency board system which “links”links the Hong
Kong dollar to the U.S.
dollar, to the “independently floating” exchange rates of Japan,
the Philippines, and South Korea. Most of the economies of Asia
Most Asian monetary authorities have adopted
“managed floats” that allow their local currency to
fluctuate within a limited range over
time as part of a larger economic policy.
Over the last few years, the value of the U.S. dollar has generally declined against most major
currencies. The , although the U.S. dollar has rebounded against some currencies in recent months. The
various economies of East Asia have responded differently to the fall
fluctuation in the value of the
U.S. dollar. Some have allowed their local currency to appreciate against
the U.S. dollarsdollar; others
have held the value of their currency against the U.S. dollar
relatively unchanged. A few have
seen their currencies depreciate in value relative to the U.S. dollar. While there is some evidence
of competitive adjustments among
some of the exchange rates, it is unclear if these adjustments
have had much impact on
exports to the United States.
While U.S. policy has generally supported the adoption of “free float” exchange
rate policies,
most of the economies of East Asia considerconsiders a “managed float” exchange
rate policy more conducive to their
economic goals and objectives. In addition, it is
uncertain if the adoption of “free float” exchange
rate policies across East Asia would
necessarily lead to a major decline in the U.S. trade deficit
with East Asia. It is possible that
U.S. complaints of “currency manipulation” and pressure on one
East Asian government
to alter its exchange rate policy may foster counter argumentsresistance from other East Asia
governments that have adopted similar exchange rate policies. This report will be
updated as
events warrant.
The exchange rate policies of some East Asian nations — in particular, China Japan,
and South Korea — have been a source of trade tension with the United States for several
years. Some analysts and Members of Congress maintain that these countries are
intentionally keeping their domestic currencies undervalued in order to keep their exports
price competitive in global markets. Some argue that these exchange rate policies
constitute “currency manipulation” and violate Article IV, Section 1(iii) of the Articles
of Agreement the International Monetary Fund, that stipulate that “each member shall
CRS-2
avoid manipulating exchange rates or the international monetary system in order to
prevent effective balance of payments adjustment or to gain an unfair competitive
advantage over other members.” Under U.S. law, the Secretary of the Treasury is required
to conduct a biannual analysis of the exchange rate policies of foreign countries and
determine if they violate Article IV, Section 1.1 In its report to Congress released in
December 2007, the U.S. Treasury “concluded that neither China nor any other major
trading partner of the United States met the requirements for designation under Section
3004 of the Act during the period”(i.e. none was manipulating its exchange rate).2
Several bills have been introduced during the 110th Congress concerning the issue
of “currency manipulation” in East Asia. These include the Currency Harmonization
Initiative Through Neutralizing Action Act of 2005 (H.R. 321), the Fair Currency Act of
2007 (H.R. 782 and S. 796), the Japan Currency Manipulation Act (H.R. 2886 and S.
1021), and the Currency Reform and Financial Markets Access Act of 2007 (S. 1677).
The economies of Asia have de facto adopted a variety of foreign exchange rate
policies.3 At one extreme, Hong Kong has maintained a “linked” exchange rate with the
U.S. dollar since 1983, under which the Hong Kong Monetary Authority (HKMA)
intervenes to keep the exchange rate between 7.75 and 7.85 Hong Kong dollars (HKD)
to the U.S. dollar.4 Such an arrangement is often referred to as a “fixed” or “pegged”
exchange rate. At the other extreme, Japan, the Philippines, and South Korea (up until
mid-March) have allowed their currencies to float freely in foreign exchange (forex)
markets over the last few years — an exchange rate arrangement often referred to as a
“free float.” However, all three nations — much like the United States — have intervened
in international currency markets if fluctuations in the exchange rate are considered too
volatile and pose a risk to the nation’s economic well-being.5
Most of the Asian economies have adopted a variety of exchange rate policies
commonly referred to as “managed floats.” Cambodia, China, Indonesia, Malaysia,
Singapore, Taiwan, Thailand, and Vietnam allow their currency to adjust in value in forex
markets so long as the fluctuations in value do not violate some other economic policy
goal (such as inflation limits or money supply constraints). In addition, some nations, such
as China and Vietnam, have adopted a type of managed float known as a “crawling peg”
— that typically includes either the gradual appreciation or depreciation of the currency

currencies.6 Table 1 lists the current de
facto exchange rate policies of East
Asia according to four general
categories: 1. Pegged; 2. Crawling Peg;
3. Managed Float; and 4. Free Float.
Categorization of a government’s
exchange rate policy can be
complicated if there is an intervention
on forex markets. For example, it has
been reported that the South Korean
government sold about $1 billion for
won on March 18, 2008, to stop a
“disorderly decline” in the value of
Korea’s currency.7 There are also
reports that Korea sold more dollars for
won in early April.8 Some forex
analysts claim that the new South
Korean government has adopted a goal
of holding the exchange rate between
the won and the U.S. dollar at 9751,000 to 1.9 However, according to
South Korea’s central bank, the Bank of
Korea, the nation’s exchange rate policy
has been a “free floating system since
December 1997.10 Based on Korea’s
past pattern, it is uncertain at this time if
the recent actions are temporary
interventions to stabilize markets, or
indications of a categorical shift in
Korea’s exchange rate policy.11

In addition, there are indications that some of the economies of East Asia monitor
the region’s exchange rates and attempt to keep the relative value of their currencies in
line with the value of selected regional currencies. These “competitive” adjustments in
exchange rates are allegedly made so as to maintain the competitiveness of their exports
on global commodity markets. For example, one scholar maintains, “Countries that trade
with China and compete with China in exports to the third market are keen not to allow
too much appreciation of their own currencies vis-à-vis the Chinese RMB [renminbi].”12
Ito also speculates, “China most likely is more willing to accept RMB appreciation if
neighboring countries, in addition [South] Korea and Thailand, allow faster
appreciation.”13

An examination of East Asian exchange rates over the last couple of years appears
to confirm both the general categorization of exchange rate policies, as well as the
supposition that some nations are engaged in competitive exchange rate management (see
Figure 1). The two currencies that appreciated the most — the free-floating Philippino
peso and the managed float Thai bhat — both rose about 23% in value between June 2005

and March 2008, but moved somewhat independently throughout the period. A second
group consisting of the crawling peg Chinese renminbi and three managed float currencies
— the Laotian kip, the Malaysian ringit, and the Singaporean dollar — rose about 15%
in value and generally moved as group, especially since January 2007. A third group
which included the managed float currencies of Cambodia and Indonesia, and the freefloating Japanese yen — appreciated about 5%, but moved separately. A final group,
which ended up relatively unchanged compared to the U.S. dollar, included the Hong
Kong dollar, the South Korean won, and the Vietnamese dong.
The pegged Hong Kong dollar remained virtually unchanged throughout the time
period considered, as would be expected. The three free-floating currencies — the
Japanese yen, the Korean won and the Philippino peso — followed three different but
fluctuating paths. In particular, the Japanese yen was the only East Asian currency that
significantly depreciated in value for much of the time period under consideration,
although it has appreciated significantly since July 2007.14 The remaining currencies —
which followed a managed float or crawling peg exchange rate — either exhibited a fairly
smooth rise in value or comparatively limited intertemporal variations. Two possible
exceptions are the Indonesian rupiah and the Thai bhat.

In general, for the last two years, there has been little apparent correlation between
the growth of U.S. trade with East Asia and changes in the relative value of East Asian
currencies. The effectiveness of the apparent effort of China, Malaysia, and Singapore
to maintain their relative exchange rates unchanged is a complex issue beyond the scope

of this short paper.15 However, official U.S. trade data appear to indicate that economic
forces in addition to relative exchange rates are influencing U.S. trade with these three
nations (see Figure 2).16 Although their currencies appreciated against the U.S. dollar in
2006 and 2007 by roughly similar amounts, U.S. trade with China, Malaysia, and
Singapore grew or fell at different rates. U.S. trade with Malaysia showed the anticipated
rise in exports and slowdown or decline in imports with the appreciation of the ringgit in
2006 and 2007. However, both China and Singapore showed strong — and differing —
increases in both exports and imports despite the strengthening of their currencies.
Implications for U.S. Trade Policy in East Asia
While U.S. policy has generally supported the adoption of “free float” exchange rate
policies, most of the economies of East Asia consider a “managed float” exchange rate
policy more conducive to their overall economic goals and objectives. In part, East Asian
governments may be resistant to a “free float” policy because of the commonly held view
in Asia that the economies with more liberal exchange rate policies suffered more during
the 1997-1998 Asian financial crisis than the economies with pegged or managed
exchange rates.17 As a result, there may be skepticism about U.S. recommendations for
adoption of “free float” exchange rate policies.
It is uncertain if the adoption of “free float” exchange rate policies by more
economies in East Asia would significantly reduce the U.S. trade deficits with countries
in the region.18 Among economists, there is no consensus that the resulting appreciation
of East Asian currencies against the U.S. dollar would either significantly increase overall
U.S. exports or reduce U.S. imports. However, for some price-sensitive industries where
U.S. companies remain competitive, the appreciation of a competing nation’s currency
may stimulate U.S. export growth and/or a decline in U.S. imports.
15
In particular, this paper does not analyze the possible “J-curve” — an economic theory that the
value of a nation’s imports may actually rise for a short period of time following the depreciation
of its currency because the increase in the price of imports may outweigh the decline in the
quantity of imports.
16
These other forces may include the U.S. federal trade deficit, comparatively low U.S. interest
rates , and/or various tariff and non-tariff trade barriers. For more information, see CRS Report
RL31032, The U.S. Trade Deficit: Causes, Consequences, and Cures, by Craig K. Elwell.

and Policy Economics, September 2006.

In his abstract of his recent study, “The Effect of Exchange Rate Changes on Trade in East
Asia,” Willem Thorbecke concluded, “The results indicate that exchange rate elasticities for trade
between Asia and the U.S. are not large enough to lend confidence that a depreciation of the
dollar would improve the U.S. trade balance with Asia.” Complete text of paper available at

East Asia’s Foreign Exchange Rate Policies
T
he exchange rate policies of some East Asian nations—in particular, China Japan, and
South Korea—have been a source of trade tension with the United States. Some analysts
and Members of Congress maintain that these countries have intentionally kept their
currencies undervalued in order to keep their exports price competitive in global markets. Some
argue that these exchange rate policies constitute “currency manipulation” and violate Article IV,
Section 1(iii) of the Articles of Agreement the International Monetary Fund, that stipulate that
“each member shall avoid manipulating exchange rates or the international monetary system in
order to prevent effective balance of payments adjustment or to gain an unfair competitive
advantage over other members.”
Under U.S. law, the Secretary of the Treasury is required to conduct a biannual analysis of the
exchange rate policies of foreign countries and determine if they violate Article IV, Section 1.1 In
its report to Congress released in April 2009, the U.S. Treasury “concluded that no major trading
partner of the United States met the standards identified in Section 3004 of the Act during the
reporting period” (i.e. none was manipulating its exchange rate).2
Several bills have been introduced during the 111th Congress concerning the issue of “currency
manipulation” or “misalignment” in general. These include the Currency Exchange Rate
Oversight Reform Act of 2009 (S. 1254), the Currency Reform for Fair Trade Act of 2009 (H.R.
2378 and S. 1027), the End the Trade Deficit Act (H.R. 1875), and the Trade Reform,
Accountability, Development, and Employment (TRADE) Act of 2009 (H.R. 3012). While these
bills address the exchange rate issue in general, it is widely understood that the main targets are in
East Asia, particularly China.
This report examines the de facto foreign exchange rate policies adopted by the monetary
authorities of East Asia. In some cases, there is a perceived discrepancy between the official (de
jure) exchange rate policy and the observed de facto exchange rate policy. This report will focus
primarily on the de facto exchange rate policies At one extreme, Hong Kong has maintained a

policies between these two extremes in the form of a “managed float.”

Much of East Asia has adopted an exchange rate policy commonly referred to as a “managed
float.” Cambodia, China, Indonesia, Malaysia, Singapore, Taiwan, Thailand, and Vietnam allow
their currency to adjust in value in forex markets so long as the fluctuations in value do not
violate some other economic policy goal
(such as inflation limits or money supply

East Asia’s Foreign Exchange Rate Policies
Another source of complication arises when there is a seeming discrepancy between the official
exchange rate policy and observed forex market trends. For example, both China and Vietnam
officially are maintaining a crawling peg policy that allows their currencies—the renminbi and
the dong, respectively—to adjust in value with respect to an undisclosed bundle of currencies
within a specified range each day. In theory, this allows the renminbi and dong to appreciate or
depreciate in value gradually over time, depending on market forces.
However, in recent months, both the renminbi and the dong have been comparatively stable in
value relative to the U.S. dollar. This has led some analysts to assert that China and Vietnam have
abandoned the crawling peg in favor of either a pegged exchange rate or a managed float. Other
analysts maintain that the stability of the value of the currencies with respect to the U.S. dollar is
an artifact of the bundle of currencies being used by China and Vietnam. Because some major
currencies have strengthened against the U.S. dollar while others have weakened, the weighted
average used by China and Vietnam in determining the band for the crawling peg has resulted in a
relatively unchanged value when compared to the U.S. dollar.
Competitive Adjustments?
There are indications that some of the economies of East Asia monitor the region’s exchange rates
and attempt to keep the relative value of their currencies in line with the value of selected
regional currencies. These “competitive” adjustments in exchange rates are allegedly made to
maintain the competitiveness of a nation’s exports on global markets. For example, one scholar
maintains, “Countries that trade with China and compete with China in exports to the third market
are keen not to allow too much appreciation of their own currencies vis-à-vis the Chinese RMB
[renminbi].”9 The scholar, Taketoshi Ito, also speculates, “China most likely is more willing to
accept RMB appreciation if neighboring countries, in addition [South] Korea and Thailand, allow
faster appreciation.”10
An examination of East Asian exchange rates over the last four years (July 2005 to June 2009)
appears to support the supposition that some nations are engaged in competitive exchange rate
management (see Figure 1). The two pegged currencies—the Hong Kong dollar and the Macau
pataca—remained virtually unchanged throughout the time period considered, as would be
expected. The two currencies that appreciated the most over the last four years—the Laotian kip
and the Chinese renminbi—appear to have followed a very similar path, which is not surprising
given Laos’ economic ties to China. The Malaysian ringgit and the Singaporean dollar seem to
have followed along the same path as the kip and renminbi until May of 2008, when the ringgit
and the Singaporean dollar began a period of depreciation against the U.S. dollar.

In a similar fashion, the two currencies with the peak level of appreciation against the U.S. dollar
over the last four years—the Philippine peso and the Thai baht—also have fluctuated along
comparable trend lines since July 2005, possibly indicating that the managed float baht was
following the lead of the free floating peso. Another pair of currencies that moved along similar
paths since July 2005 were the Indonesian rupiah and the South Korean won; both currencies
have depreciated against the U.S. dollar during the last four years, with the won down by over
20%. The reasons for the apparent link between the rupiah and won is unclear.
Exchange Rates and U.S. Trade
There is a widely held notion that if a nation’s currency appreciates in value relative to other
nations’ currencies, its exports will tend to decline and its imports will tend to rise. In practice,
there has been little apparent correlation in recent years between the growth of U.S. trade with
East Asia and changes in the relative value of East Asian currencies. The example of U.S. trade
with China, Malaysia, and Singapore—three significant trading partners in East Asia whose
currencies have followed similar paths over much of the last four years—shows that changes in
relative exchange rates do not necessarily lead to the anticipated changes in bilateral trade flows.

East Asia’s Foreign Exchange Rate Policies
The reasons for the comparative stability of the relative exchange rates of China, Malaysia, and
Singapore is a complex issue beyond the scope of this short paper.11 However, official U.S. trade
data appear to indicate that economic forces in addition to relative exchange rates are influencing
U.S. trade with these three nations (see Figure 2).12 Although their currencies appreciated against
the U.S. dollar in 2006, 2007, and 2008 by similar amounts, U.S. trade with China, Malaysia, and
Singapore grew or fell at different rates. U.S. trade with Malaysia showed the anticipated rise in
U.S. exports and slowdown or decline in U.S. imports with the appreciation of the ringgit.
However, both China and Singapore showed strong—and differing—increases in both U.S.
exports and imports despite the strengthening of their currencies relative to the U.S. dollar.
Implications for U.S. Trade Policy in East Asia
While U.S. policy has generally supported the adoption of “free float” exchange rate policies,
most East Asian governments consider a “managed float” exchange rate policy more conducive to
their overall economic goals and objectives. In part, East Asian governments may be resistant to a
“free float” policy because of the commonly held view in Asia that the economies with more
liberal exchange rate policies suffered more during the 1997-1998 Asian financial crisis than the
economies with pegged or managed exchange rates.13 As a result, there may be skepticism about
U.S. recommendations for adoption of “free float” exchange rate policies.
In addition, as indicated above, it is uncertain if the adoption of “free float” exchange rate policies
by more monetary authorities in East Asia would significantly reduce the U.S. trade deficits with
countries in the region. 14 Among economists, there is no consensus that the resulting appreciation
of East Asian currencies against the U.S. dollar would either significantly increase overall U.S.
exports or reduce U.S. imports. However, for some price-sensitive industries where U.S.
companies are competitive, the appreciation of a competing nation’s currency may stimulate U.S.
export growth and/or a decline in U.S. imports.
11
In particular, this paper does not analyze the possible “J-curve”—an economic theory that the value of a nation’s
imports may actually rise for a short period of time following the depreciation of its currency because the increase in
the price of imports may outweigh the decline in the quantity of imports.
12
These other forces may include the U.S. federal trade deficit, comparatively low U.S. interest rates , and/or various
tariff and non-tariff trade barriers. For more information, see CRS Report RL31032, The U.S. Trade Deficit: Causes,
Consequences, and Cures, by Craig K. Elwell.

In his abstract of his 2006 study, “The Effect of Exchange Rate Changes on Trade in East Asia,” Willem Thorbecke
concluded, “The results indicate that exchange rate elasticities for trade between Asia and the U.S. are not large enough
to lend confidence that a depreciation of the dollar would improve the U.S. trade balance with Asia.” Complete text of
