What Guaranty Trust Bank SL Ltd does
Guaranty Trust Bank (Sierra Leone) Limited is a private commercial bank incorporated in Freetown, Sierra Leone, operating as a wholly-owned subsidiary of Guaranty Trust Holding Company (GTCO) PLC of Nigeria. The bank commenced operations in January 2002 through the acquisition of a 90% stake in the former First Merchant Bank of Sierra Leone and, after thirteen years, became the third-largest bank in the country. Within Sierra Leone it serves individual consumers, small and medium-sized enterprises, mid-to-large corporates, NGOs and faith-based organizations, and high-net-worth clients through private banking. Named enterprise relationships span telecommunications, petroleum, mining, government parastatals, education, and insurance sectors.
The bank delivers its services through a physical branch and ATM network, plus a digital banking stack comprising Internet Banking (ibank.gtb.sl), a mobile banking application, USSD channels (*878# and *9737#), and the 24/7 GTConnect self-service contact centre that handles approximately 90% of banking transactions by telephone. Its core digital products are GAPS (a web-based batch payment system supporting payroll, vendor, FX, and tax payments with role-based authentication and two-factor token security), GTPay (an internet payment gateway accepting Mastercard, VISA, and Interswitch cards), and GTCollections (a multi-currency e-collection platform used by schools, embassies, insurance firms, and realtors). Card products include the GTBank Debit Mastercard, GTBank Corporate Credit Card, and GTBank Corporate Prepaid Cards issued in partnership with Mastercard Worldwide.
The revenue model combines interest income from lending (overdrafts, asset financing, term loans, trade finance), transaction and service fees (monthly account maintenance, cheque book, ATM, and card fees), foreign exchange commissions on spot, forwards, swaps, and SWIFT transfers, trade finance fees from letters of credit and bank guarantees, and digital banking channel revenue. GTM is executed through an enterprise field-sales motion supported by relationship managers targeting mid-to-large corporates, alongside direct and self-service digital channels for retail and SME customers. The Sierra Leone entity sits within a broader GTCO group spanning eleven countries (Nigeria, Ghana, Sierra Leone, Gambia, Liberia, Cote D'Ivoire, Kenya, Rwanda, Tanzania, Uganda, and the United Kingdom) with consolidated group assets exceeding N3.11 trillion.
