It's interesting that the Somali shilling is still being used, not only in Somalia but in the Ogaden region of Ethiopia, which is inhabited by Somalis.

From their conversations, it is clear that most Ethiopian Somalis feel culturally and socially closer to their kin in Somalia and northern Kenya than they do to the Ethiopian highlanders.

Trade with Somalia is also much greater than trade with the rest of Ethiopia. The Somali shilling is the main currency in some areas in the region.
