Due to economic chaos in Sudan, foreign investors cannot easily receive their bond payments. There is no legal possibility to directly convert bond payments into dollars. Therefore, it is recommended to reinvest, e.g. in real estate, using the money paid out in local currency. The main reason for impossibility of payment in dollars is the independence of South Sudan in July 2011. Since South Sudan was the country's main source for oil as well as for dollars, now it finds itself cut off. The central bank hardly allows conversion of shares or bonds into dollars in order to preserve money for food imports.
