The review of the current composition of the SDR basket was scheduled to be finished by the end of 2015. The fund had been expected to include the Chinese yuan currency into its supplementary foreign exchange reserve assets on January 1, 2016.
“The extension would also allow users sufficient lead time to adjust in the event that a decision were to be taken to add a new currency to the SDR basket,” the statement published on the IMF website read.
The current SDR basket consists of US dollars, euros, British pounds and the Japanese yen. The IMF conducts a key international currency review every five years.
