Uganda Commercial Bank (UCB) was established by an Act of Parliament, "The Uganda Commercial Bank Act, 1965". The new bank was to replace the Uganda Credit and Savings Bank.[1]
The bank extended banking services to rural areas, and steadily expanded its branch network throughout the 1960s and 1970s. In 1971/72, following the nationalisation of foreign-owned businesses by the government of Idi Amin, the bank's branch network expanded rapidly when it took over most of the branches of foreign-owned banks - leaving Uganda Commercial Bank with nearly a monopoly in banking markets outside Kampala. The fall of Amin's government in 1979 brought a revival of foreign development assistance to Uganda, some of which was channelled through Uganda Commercial Bank, leading to an increase in its share of medium-term financing and its loan portfolio. The bank's branches were also used to perform functions for the government, such as the handling of payments of taxes and school fees.[2]
In the late 1980s, then chairman and managing director Dr. Frank Alfred Mwine led the bank in opening 130 new branches and further expanding its investments. Dr. Mwine was a Harvard Law educated Ugandan and a World Bank executive. By the 1990s UCB held around 50% of commercial bank deposits and had 190 of the 270 bank branches in the country. The second largest branch network at that time, the Co-operative Bank, had 24 branches.[2]
