The International Monetary Fund created the SDR in the late 1960s to supplement the gold and other currencies held by countries as their reserves. The value of 1 SDR was initially defined as the same amount of gold as 1 USD. At the time, the USD was convertible into gold, so most countries chose to hold the bulk of their reserves in dollars instead of gold.
