Considering the importance of having a modern state-of-the-art payment and settlement system, BSL has been actively working to implement a modern payment and settlement system in Sierra Leone. The Bank in 2009 initiated action to automate its Payment and Settlement system by first establishing a Payment System Act and a Payments System Steering Committee that forms the highest policy decision making body on Payments Systems issues. With financial assistance from African Development Bank (AfDB) through the West Africa Monetary Institute (WAMI), BSL in 2013 implemented the Automated Cheque Processing (ACP), Automated Clearing House (ACH), Real Time Gross Settlement (RTGS) and Scripless Securities Settlement (SSS) systems. These systems now form the media for interbank funds transfer country wide. This initiative has resulted in some gradual acceptance and penetration of non-cash payment modes. Cash however; continue to be the predominant mode in retail payments with retail electronic payments and acceptance of cheques also gradually picking up.
