The period 1892 - 1952, there was an enquiry by the then colonial administration to investigate banking practice in Nigeria. The G. D. Paton Report which emanated from the enquiry was the basis for the first Banking Ordinance of 1952. The ordinance was designed to ensure orderly commercial banking and to prevent the establishment of unviable banks. A draft legislation for the establishment of Central Bank of Nigeria was presented to the House of Representatives in March, 1958. The Act was fully implemented on 1 July, 1959 when the Central Bank of Nigeria came into full operations.The Central Bank Act, 1958 (as amended) and the Banking Decree 1969 (as amended) constituted the legal framework within which the CBN operates and regulates banks. The wide range of economic liberalization and deregulation measures following the adoption, in 1986, of a Structural Adjustment Programme (SAP) resulted in the emergence of more banks and other financial intermediaries. The Banks and Other Financial Institutions (BOFI) Decrees 24 and 25 of 1991, which repealed the Banking Decree 1969 and all its amendments, were, therefore, enacted to strengthen and extend the powers of CBN to cover the new institutions in order to enhance the effectiveness of monetary policy, regulation and supervision of banks as well as non-banking financial institutions.
