Notes:
International reserve units created by the International
Monetary Fund in 1969 to supplement the limited supplies of gold
and dollars which had been the prime stable monetary assets. By
1986, $342.1 billion worth of SDRs had been allocated by the IMF
to member countries according to a formula based on their IMF
assessments .... From 1974 to 1980, the SDR was pegged to a 16-currency basket. Since 1981, the value of the SDR has been based
on a basket of currencies of the Group of 5, which comprises
France, Japan, the United Kingdom, the United States, and Western
Germany.
