Special Drawing Rights

Special Drawing Rights (SDRs) is a potential claim on the freely usable currencies of International Monetary Fund members.

Purpose

SDRs are used as a unit of account by the IMF and several other international organizations. A few countries peg their currencies against SDRs, and it is also used to denominate some private international financial instruments. For example, the Warsaw convention, which regulates liability for international carriage of persons, luggage or goods by air uses SDRs to value the maximum liability of the carrier.

In Europe, the Euro is displacing the SDR as a basis to set values of various currencies, including Latvian lats. This is a result of the ERM II convergence criteria which now apply to states entering the European Union.

SDRs basically were created to replace gold in large international transactions. Being that under a strict (international) gold standard, the quantity of gold worldwide is relatively fixed, and the economies of all participating IMF members as an aggregate are growing, a perceived need arose to increase the supply of the basic unit or standard proportionately. Thus SDRs, or "paper gold", are credits that nations with balance of trade surpluses can 'draw' upon nations with balance of trade deficits.

So-called "paper gold" is little more than an accounting transaction within a ledger of accounts, which eliminates the logistical and security problems of shipping gold back and forth across borders to settle national accounts.

Joseph Stiglitz has argued that usage by central banks of SDRs as foreign exchange reserve could be viewed as the prelude to the creation of a single world currency.[2] It has also been suggested that having holders of US dollars convert those dollars into SDRs would allow diversification away from the dollar without accelerating the decline of the value of the dollar.[3][4]
