 To establish the bank, the Sudanese government nationalized the National Bank of Egypt's operations in the Sudan (some seven branches), and combined them with the Sudanese currency board.In addition to the normal duties of a central bank, which may include minting coins and issuing banknotes, managing a country's internal and external accounting, and setting monetary policy and interest rates, Sudan's central bank is also responsible for fostering Islamic banking.After Sudan introduced Islamic law (Sharia) in 1984, the banking and financial industry changed its practices to conform with Sharia.
