SDRs are international reserve assets created by international Monetary Fund to supplement other reserve assets that periodically have been allocated to IMF members in proportion to their respective quotas. SDRs are not considered liabilities of the Fund, and IMF members to whom SDRs are allocated do not incur actual (unconditional) liabilities to repay SDR allocations.The fund determines the value of SDRs daily by summing, in USA dollars, the values of a weighted basket of currencies. The weight and baskets are subject to revision from time to time. SDRs can be used to acquire other member’s currencies (foreign exchange), to settle financial obligations, and to extend loans.
