s were costing too little in international markets, and imports from abroad were costing the Japanese too much. This undervaluation was reflected in the current account balance, which had risen from the deficits of the early 1960s to a then-large surplus of US$5.8 billion in 1971. The belief that the yen, and several other major currencies, were undervalued motivated the United States' actions in 1971.

Yen and major currencies float

Following the United States' measures to devalue the dollar in the summer of 1971, the Japanese government agreed to a new, fixed exchange rate as part of the Smithsonian Agreement
Smithsonian Agreement
The Smithsonian Agreement was a December 1971 agreement that ended the fixed exchange rates established at the Bretton Woods Conference of 1944.-History:...

, signed at the end of the year. This agreement set the exchange rate at ¥308 per US$1. However, the new fixed rates of the Smithsonian Agreement were difficult to maintain in the face of supply and demand pressures in the foreign-exchange market. In early 1973, the rates were abandoned, and the major nations of the world allowed their currencies to float.

Japanese government intervention in the currency market

In the 1970s, Japanese government and business people were very concerned that a rise in the value of the yen would hurt export growth by making Japanese products less competitive and would damage the industrial base. The government therefore continued to intervene heavily in foreign-exchange marketing (buying or selling dollars), even after the 1973 decision to allow the yen to float.

Despite intervention, market pressures caused the yen to continue climbing in value, peaking temporarily at an average of ¥271 per US$1 in 1973 before the impact of the 1973 oil crisis
1973 oil crisis
The 1973 oil crisis started in October 1973, when the members of Organization of Arab Petroleum Exporting Countries or the OAPEC proclaimed an oil embargo.

, with the yen dropping to ¥227 by 1980.

Yen in the early 1980s

During the first half of the 1980s, the yen failed to rise in value even though current account surpluses returned and grew quickly. From ¥221 in 1981, the average value of the yen actually dropped to ¥239 in 1985. The rise in the current account surplus generated stronger demand for yen in foreign-exchange markets, but this trade-related demand for yen was offset by other factors.

, led to a large net outflow of capital from Japan. This capital flow increased the supply of yen in foreign-exchange markets, as Japanese investors changed their yen for other currencies (mainly dollars) to invest overseas. This kept the yen weak relative to the dollar and fostered the rapid rise in the Japanese trade surplus that took place in the 1980s.

Effect of the Plaza Accord

In 1985 a dramatic change began. Finance officials from major nations signed an agreement (the Plaza Accord

) affirming that the dollar was overvalued (and, therefore, the yen undervalued). This agreement, and shifting supply and demand pressures in the markets, led to a rapid rise in the value of the yen. From its average of ¥239 per US$1 in 1985, the yen rose to a peak of ¥128 in 1988, virtually doubling its value relative to the dollar. After declining somewhat in 1989 and 1990, it reached a new high of ¥123 to US$1 in December 1992. In April 1995, the yen hit a peak of under 80 yen per dollar, temporarily making Japan's economy nearly the size of the US.

In 1955 the current type of aluminium 1 yen was introduced, along with unholed, nickel 50 yen. In 1957, silver 100 yen pieces were introduced. These were replaced in 1967 by the current, cupro-nickel type, along with the holed 50 yen coin. In 1982 the first 500 yen coins were introduced.

the 500 yen coin was the highest-valued coin to be used regularly in the world (depending on exchange rates, the rarely-used 5 Cuban convertible peso coin is sometimes the highest-valued), with value of over US$6. Because of this high face value, the 500 yen has been a favorite target for counterfeiters; it was counterfeited to such an extent that in 2000 a new series of coins was issued with various security features, but counterfeiting continued.

The 1 yen coin is made out of 100% aluminum and can float on water if placed correctly.

The current commemorative 500 and 1000 yen coin series began circulation in December, 2009, with 47 unique designs for each with only one available from banks in each prefecture. 100000 of each have been minted and they are all currently (as of October, 2010) still available in major banks at face value. Someone collecting one of each coin would need to invest 70500 yen, thus creating a major source of income for the Japanese government. Even though all commemorative coins can be used, they are not seen often in typical daily use and normally do not circulate.

 has been the exclusive note issuing authority. The bank has issued five series after World War II. Series E, the current series, consists of ¥1000, ¥2000, ¥5000, and ¥10,000. The ¥2000 bills are rare these days, and often not accepted as a means of payment, not even in dispensing machines.

Determinants of value

Beginning in December 1931, Japan gradually shifted from the gold standard system to the managed currency system.

 for the yen is governed by the desire of foreigners to buy goods and services in Japan and by their interest in investing in Japan (buying yen-denominated real and financial assets).

Since the 1990s, the Bank of Japan, the country's central bank, has kept interest rates low in order to spur economic growth. Short-term lending rates have responded to this monetary relaxation and fell from 3.7% to 1.3% between 1993 and 2008. Low interest rates combined with a ready liquidity for the yen prompted investors to borrow money in Japan and invest it in other countries (a practice known as carry trade). This has helped to keep the value of the yen low compared to other currencies.

 (SDR) valuation is an IMF basket of currencies, including the Japanese yen. The SDR is linked to a basket of currencies with 41.9% for the dollar, 37.4% for the euro, 11.3% for the pound sterling, and 9.4% for the yen (as of 2011). The percentage for the yen has however declined from 18% in 2000. The exchange rate for the Japanese yen is expressed in terms of currency units per U.S. dollar; other rates are expressed as U.S. dollars per currency unit. The SDR currency value is calculated daily and the valuation basket is reviewed and adjusted every five years. The SDR was created in 1969 to support the fixed exchange system.
