special drawing rights (SDR) valuation is an IMF basket of currencies, including the Japanese yen. The SDR is linked to a basket of five different currencies, with 41.73% for the U.S. dollar, 30.93% for the Euro, 10.92% for the Chinese renminbi, 8.33% for the Japanese yen, and 8.09% for the pound sterling (as of 2016).[38] 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.

Historical exchange rate

Before the war commenced, the yen traded on an average of 3.6 yen to the dollar. During the war, because of overprinting and inflation as the Empire occupied more territory, the yen went as low as 600 yen to the USD.

When McArthur and the US forces entered Japan in 1945, they decreed an official conversion rate of 15 yen to the USD.

Within 1945-1946: the rate tanked to 50 yen to the USD because of the ongoing inflation. During the first half of 1946, the rate fluctuated to 66 yen to the USD and eventually plummeting to 600 yen to the dollar by 1947 because of the failure of the economic remedies.

Eventually, the peg was officially moved to 270 yen to the dollar in 1948 before being adjusted again from 1949–1971 to 360 yen to the dollar.
