Valuation of the Special Drawing Right
Method of Valuation
1. Effective January 1, 1981, the value of one special drawing right shall be the sum of the values of specified amounts of the currencies listed in 2 below, the amounts of these currencies to be determined on December 31, 1980 in a manner that will ensure that, at the average exchange rates for the three-month period ending on that date, the shares of the currencies in the value of the special drawing right correspond to the weights specified for each currency in 2 below.
2. On the basis of changes in members’ exports of goods and services and in official balances of members’ currencies held by other members since the previous review of the method of valuation of the SDR conducted in March 1978, that the currencies and weights referred to in 1 above shall be as follows:
3. The list of the currencies that determine the value of the special drawing right, and the amounts of these currencies, shall be revised with effect on January 1, 1986 and on the first day of each subsequent period of five years in accordance with the following principles, unless the Fund decides otherwise in connection with a revision:
- The currencies determining the value of the special drawing right shall be the currencies of the five members whose exports of goods and services during the five-year period ending 12 months before the effective date of the revision had the largest value, provided that a currency shall not replace another currency included in the list at the time of the determination unless the value of the exports of goods and services of the issuer of the former currency during the relevant period exceeds that of the issuer of the latter currency by at least 1 percent.
- The amounts of the five currencies referred to in a. above shall be determined on the last working day preceding the effective date of the relevant revision in a manner that will ensure that, at the average exchange rates for the three-month period ending on that date, the shares of these currencies in the value of the special drawing right correspond to percentage weights for these currencies, which shall be established for each currency in accordance with c. below.
- The percentage weights shall reflect the value of the balances of that currency held at the end of each year by the monetary authorities of other members and the value of the exports of goods and services of the issuer of the currency over the relevant five-year period referred to in a. above, in a manner that would maintain broadly the relative significance of the factors that underlie the percentage weights in paragraph 2 above. The percentage weights shall be rounded to the nearest 1 percent or as may be convenient.
4. The determination of the amounts of the currencies in accordance with 1 and 3 above shall be made in a manner that will ensure that the value of the special drawing right in terms of currencies on the last working day preceding the five-year period for which the determination is made will be the same under the valuation in effect before and after revision.

SDR Valuation Basket
The Executive Board, having reviewed the list of the currencies, and the weights of these currencies, that determine the value of the special drawing right, in accordance with Decision No. 6631-(80/145) G/S, adopted September 17, 1980, decides that, with effect from January 1, 1991, the list of the currencies in the SDR valuation basket shall remain the same, and the weight of each of these currencies to be used to calculate the amount of each of these currencies in the basket will be as follows:

SDR Valuation Basket—Guidelines for the Calculation of Currency Amounts
(1) Under all circumstances, the currency units will be determined in a manner which would ensure that the value of the SDR calculated on December 31 on the basis of the new basket will be the same as that actually prevailing on that day.
(2) The currency amounts calculated for the new basket will be expressed in two significant digits provided that the deviation of the percentage share of each currency in the value of the SDR, resulting from the application of the average exchange rates for October-December, from the percentage weight as determined under paragraph 3(c) of Executive Board Decision No. 6631-(80/145) adopted September 17, 1980 is the minimum on average and will not exceed one half percentage point for any currency.
(3) If a solution cannot be obtained by the application of the principles set forth in (2) above, the calculation shall be made applying the same principles but expressing the amount of each currency in three significant digits, and if no solution is found with three significant digits then the calculation shall be made applying the same principles but expressing the amount of each currency in four significant digits.
(4) If more than one solution is found in the calculation at the level of two, three, or four significant digits, the solution that has the smallest average deviation will be employed.

Method of Collecting Exchange Rates for the Calculation of the Value of the SDR for the Purposes of Rule O-2(a)
1. For the purpose of determining the value of the United States dollar in terms of the special drawing right pursuant to Rule O-2(a), the equivalents in United States dollars of the amounts of currencies specified in Rule O-1 shall be based on spot exchange rates against the United States dollar. For each currency the exchange rate shall be the middle rate between the buying and selling rates at noon in the London exchange market as determined by the Bank of England.
2. If the exchange rate for any currency cannot be obtained from the London exchange market, the rate shall be the middle rate at noon in the New York exchange market determined by the Fund on the basis of the buying and selling rates communicated by the Federal Reserve Bank of New York or, if not available there, the middle rate determined by the Fund on the basis of the buying and selling rates at the fixing in the Frankfurt exchange market communicated by the Deutsche Bundesbank. If the rate for any currency against the United States dollar cannot be obtained directly in any of these markets, the rate shall be calculated indirectly by use of a cross rate against another currency specified in Rule O-l.
3. If on any day the exchange rate for a currency cannot be obtained in accordance with 1 or 2 above, the rate for that day shall be the latest rate determined in accordance with 1 or 2 above, provided that after the second business day the Fund shall determine the rate.
