All IMF participating states have allocations of SDRs. By your definition, the IMF is "pegged" to the currency of Afghanistan.
I'm afraid you may have misunderstood. The SDR is a time-varying basket of USD, EUR, RMB, GBP, and JPY. At time of writing Afghanis are not part of SDR, even though Afghanistan owns some SDR.
