Japan depends on the Ministry of Finance for its exchange rate policies. However, it is the Bank of Japan Policy Board that publishes the exchange rate statements. The interest rates set by the Bank of Japan has greatly influenced the exchange rate of the yen. A rise in the interest rate results in higher returns from yen assets. This further pushes up the currency. This has a negative impact on the export side, although the import bills decline.
Some of the unique characteristics of the yen are:
The yen was pegged at 1 USD = ¥360 in April 1949. It remained at this value for a period of 22 years until 1971.Significant economic growth was witnessed during this period. However, with the collapse of the Bretton Woods System, the floating exchange rate method was adopted.
The Japanese yen has been appreciating since December 1971. During the 1971-1985 phase, the yen appreciated without anyfluctuation in trend. After the Plaza Accord in 1985, the Japanese currency spiked. Against this backdrop, Japanese industries invested abroad to capture offshore markets. This, in turn, depressed domestic industrial growth and employment. Domestic investments dipped and all these led to deflation in the Japanese economy. At this juncture, the Japanese government intervened in the forex market to curb the yen appreciation in order to boost the export sector.
In early 2009, the yen benefited from the economic crisis. This was mainly due to the high repatriation of Japan’s extensive foreign investments.
