The reserve position of the international monetary fund, that is, the ordinary drawing right. According to IMF regulations, the share of member countries determines the amount of loans they can get from the IMF. Loans are divided into gold part (later changed to reserve part) and credit part. The original gold part (that is, the gold or foreign exchange part of 25% paid by member countries to the IMF) is unconditional; Credit loans are divided into four grades, all of which are conditional. The higher the level, the higher the conditions. When the IMF holds less than 75% of the national currency of a member country, its lending capacity will increase accordingly. This part is called the super-gold part, and this part of lending is unconditional. Therefore, the net reserve position of a member country in the IMF is equal to its gold part loan plus super gold part loan, that is, it is equal to its share minus the amount of the national currency of the member country held by the IMF. All member countries have listed their net reserve positions in the International Monetary Fund as official reserve assets.

Special Drawing Rights (SDR) is a unit of account founded by the International Monetary Fund. This is the right to use the funds allocated by the International Monetary Fund to member countries. It is a supplement to ordinary SDR and can be used as an international reserve of IMF member countries together with gold and foreign exchange. The SDR part of a country's international reserves refers to its credit balance in the IMF SDR account.

There are three differences between SDR and ordinary SDR:

First, SDR is an asset allocated by IMF to member countries according to their shares, and member countries can freely control and use it; Ordinary drawing right is the right of IMF to draw according to the share paid by member countries, and the maximum amount does not exceed 125% of the paid share. Its credit part cannot be freely withdrawn.

Second, using SDR is equivalent to exercising the right to use funds, which is expenditure and reduction of assets; The use of ordinary drawing rights is equivalent to the use of the right to obtain credit, which is the borrower and increases the debt.

Third, there is no need to repay after using SDR; Ordinary drawing rights usually need to be repaid after 3 to 5 years.

Ordinary drawing rights are just loans, and special drawing rights are assets.
