Monetary policies are very important in any economy. However, they are dominantly hectic and characterized with frequent changes in developing countries. In Sudan, there were many changes during the past three decades, mostly were not compatible with coherent economic logic. The country's economy degenerated from being the leading African economy after dependance in 1956 to the 1960's to stand on the brink of economic extinction in the 2000's and virtual bankruptcy in 2012. Frequent changes in macroeconomic policies affected the essence and logic of money supply and demand. That eventually affected the economic sectors and their productive abilities.
