Capital controls restrict the ability of
households and businesses to hold assets
denominated in foreign currency. Capital
controls can restrict either the inflow of
capital or the outflow of capital. Restrictions
on the inflow of capital can include
bans on foreign-owned deposits in
domestic banks and thrifts, foreign purchase
of domestically issued stocks and
bonds, and foreign purchase of tangible
capital such as land and plant and
equipment. Restrictions on the outflow of
capital can prevent citizens from holding
foreign currency deposits in foreign
banks and thrifts, purchasing stocks and
bonds issued in foreign countries, and
purchasing land, plant, and equipment in
foreign countries.
Governments have various motives for
imposing capital controls. In the 1970s,
Germany imposed restrictions on the
inflow of foreign capital out of concern
for the competitiveness of its exports in
foreign markets (Allen, 2001, 228). Foreigners
purchasing German bonds tended
to bid up the value of Germany’s currency
in foreign exchange markets. As
the value of a country’s domestic currency
climbs in foreign exchange markets,
its exports become costlier in
foreign markets. Germany banned interest
payments on large bank accounts held by
nonresidents and nonresident purchase of
bonds. Germany lifted these restrictions
in 1981. Japan, another country concerned
about the competitiveness of its exports
abroad, banned foreign ownership of
Japanese assets until 1980. In 1984,
Japan lifted remaining capital controls.
Governments more concerned about
currency depreciation are more likely to
impose restrictions on the outflow of capital.
Currency depreciation can unleash a
wave of inflation. It makes foreign
imports costlier. The United Kingdom
enforced restrictions on capital outflows
until 1979. France and Italy restricted
capital outflows until 1986 (Allen, 2001,
228). Developing countries may restrict
capital outflows because they want to
keep capital at home to finance domestic
economic development. They may allow
their citizens to convert domestic currency
into U.S. dollars if the dollars go
toward the purchase of a tractor or other
piece of capital equipment. They may not
allow their citizens to convert domestic
currency into U.S. dollars to hold a bank
account in a Miami bank.
The United States has been among the
countries most inclined to allow the
unrestricted inflow and outflow of capital.
In the 1960s, however, the United States
levied an “interest rate equalization tax”
that removed the incentive of U.S. citizens
to purchase foreign interest-bearing
assets (Allen, 2001, 228). The tax lasted
into the 1970s. The North American Free
Trade Agreement (NAFTA) provides for
the free movement of capital between
Canada, Mexico, and the United States
with a few exceptions. The United States
prohibits foreign ownership of radio stations,
and limits the percent of a U.S. airline
that can be owned by foreign investors.
Mexico prohibits foreign investment in
its domestic oil business. In 2005, China
make a takeover bid for Unical, a large U.S.
oil company. Although Chinese purchase
of Unical did not strictly violate U.S.
law, China dropped the takeover bid after
strong opposition arose in Congress.
Opponents of the takeover bid were concerned
about the national defense repercussions
of letting China own a large
stake in the U.S. oil industry.
Part of the trend toward globalization
has been the removal of all capital controls
by both developed and developing
countries. Capital controls as economic
policy have now largely lost favor. Some
exceptions include cases where national
defense may be at risk.
