Japanese yen

The yen is the official currency of Japan. It is the third-most traded currency in the foreign exchange market, after the United States dollar (US

) and the euro. It is also widely used as a third reserve currency after the US dollar and the euro. The New Currency Act of 1871 introduced Japan's modern currency system, with the yen defined as of gold, or of silver, and divided decimally into 100 sen or 1,000 rin. The yen replaced the previous Tokugawa coinage as well as the various hansatsu paper currencies issued by feudal han (fiefs). The Bank of Japan was founded in 1882 and given a monopoly on controlling the money supply. Following World War II, the yen lost much of its prewar value. To stabilize the Japanese economy, the exchange rate of the yen was fixed at ¥360 per US

as part of the Bretton Woods system. When that system was abandoned in 1971, the yen became undervalued and was allowed to float. The yen had appreciated to a peak of ¥271 per US

in 1973, then underwent periods of depreciation and appreciation due to the 1973 oil crisis, arriving at a value of ¥227 per US

by 1980. Since 1973, the Japanese government has maintained a policy of currency intervention, so the yen is under a "dirty float" regime. The Japanese government focused on a competitive export market, and tried to ensure a low exchange rate for the yen through a trade surplus. The Plaza Accord of 1985 temporarily changed this situation; the exchange rate fell from its average of ¥239 per dollar in 1985 to ¥128 in 1988 and led to a peak rate of ¥80 against the US$ in 1995, effectively increasing the value of Japan's GDP in dollar terms to almost that of the United States. Since that time, however, the world price of the yen has greatly decreased. The Bank of Japan maintains a policy of zero to near-zero interest rates and the Japanese government has previously had a strict anti-inflation policy. Yen derives from the Japanese word 圓, which borrows its phonetic reading from Chinese yuan, similar to North Korean won and South Korean won.

Gold standard

A gold standard is a monetary system in which the standard economic unit of account is based on a fixed quantity of gold. The gold standard was the basis for the international monetary system from the 1870s to the early 1920s, and from the late 1920s to 1932 as well as from 1944 until 1971 when the United States unilaterally terminated convertibility of the US dollar to gold, effectively ending the Bretton Woods system. Many states nonetheless hold substantial gold reserves.

Bretton Woods system

The Bretton Woods system of monetary management established the rules for commercial relations among the United States, Canada, Western European countries, and Australia among 44 other countries after the 1944 Bretton Woods Agreement. The Bretton Woods system was the first example of a fully negotiated monetary order intended to govern monetary relations among independent states.
