===Historical valuation===
At the time of the XDR's creation in 1969, the [[United States dollar]] was backed by the [[gold standard]] and the XDR was fixed at 1/35 [[troy ounce]] of [[gold]] or exactly 1 US dollar.<ref name="white1" /> After the [[Nixon Shock]] of 1971 and during the collapse of the [[Bretton Woods system]] between 1971 and 1973, the XDR initially remained fixed relative to the nominal international price of gold, even the value of the [[United States dollar]] dropped to $38 per troy ounce in 1972 and to $42 2⁄9 per troy ounce in 1973. On 1 July 1974, the XDR instead became defined by a [[currency basket]] of 16 currencies.<ref name="white2" />

On January 1, 1981, the five-year schedule was introduced and the XDR basket was reduced to five currencies: the [[United States dollar]], the [[Deutsche mark]], the [[French franc]], the [[British pound]], and the [[Japanese yen]].<ref>{{cite web |url=http://stats.oecd.org/metadata/publish.asp?co%3DXDR........%26ds%3D1 |access-date=2015-03-07 |url-status=dead |archive-url=https://web.archive.org/web/20150402094743/http://stats.oecd.org/metadata/publish.asp?co=XDR........&ds=1 |archive-date=2015-04-02 | title=OECD Reference Metadata Report: Main Economic Indicators }}</ref> When the [[euro]] was introduced in January 1999, it replaced the German mark and French franc and the basket consisted of four currencies.<ref name=factsheet />

In November 2010, the IMF determined that China's [[renminbi]] met the export requirement but failed to meet the "freely usable" requirement and thus was not included in the XDR basket taking effect on 1 January 2011. In November 2015, the IMF announced that the renminbi now met the "freely usable" requirement and would be included in the next basket definition, changing its size back to five currencies. The effective date of the re-evaluation was postponed to October 1, 2016, in order to "allow users sufficient lead time to adjust".<ref name=2015review>{{cite web|title=IMF's Executive Board Completes Review of SDR Basket, Includes Chinese Renminbi |url=http://www.imf.org/external/np/sec/pr/2015/pr15540.htm|publisher=IMF|access-date=December 5, 2015|date=November 30, 2015}}</ref><ref name=2016weights>{{cite web|title=IMF Executive Board Completes the 2015 Review of SDR Valuation |url=http://www.imf.org/external/np/sec/pr/2015/pr15543.htm |publisher=IMF|access-date=December 5, 2015|date=December 1, 2015}}</ref> In 2016, the renminbi was added to the basket with a 10.9% weighting.<ref name=":024">{{Cite book |last=Jin |first=Keyu |title=The New China Playbook: Beyond Socialism and Capitalism |date=2023 |publisher=Viking |isbn=978-1-9848-7828-1 |location=New York |author-link=Keyu Jin}}</ref>{{Rp|page=259}}

In March 2021, the IMF announced that the next re-evaluation, normally scheduled for 1 October 2021, would be postponed to 1 August 2022, in order to prevent the basket's definition from changing during the [[COVID-19 pandemic]].<ref>{{cite web|title=Review of The Method of Valuation of The SDR—Proposed Extension of The Valuation Of The SDR Basket and Modification of The Date Of Effect of A New Basket|url=https://www.imf.org/en/Publications/Policy-Papers/Issues/2021/03/15/Review-of-The-Method-of-Valuation-of-The-SDR-Proposed-Extension-of-The-Valuation-Of-The-SDR-50265|publisher=IMF|access-date=2021-03-15|date=March 15, 2021}}</ref>
