Construction and Business Bank S.C. (CBB) is a wholly government–owned public enterprise and successor of the Housing and Savings Bank (HSB) which was formed in 1975 through the merger of two financial institutions namely, Imperial Savings and Home Ownership Association, and Savings and Mortgage Corporation of Ethiopia which were nationalized at the on-set of the socialist era of Ethiopia.

HSB's objectives were granting long-term loans for residential housing and commercial building construction, purchase and renovation by mobilizing financial resources through ordinary savings, time deposits and long-term borrowings. For about twenty years since 1975, HSB has made important contribution to the development of housing in the country in which it hitherto enjoyed the reputation as a household name.

Following the market-based economic policy of the country and the ensuing economic reform programs initiated by the government in 1992, HSB was reconstituted as Construction and Business Bank in September 1994 by regulation No. 203/94 with an authorized capital of Birr 71.8 million. The regulation gave CBB the mandate to provide universal banking services. In line with this, CBB has ventured into commercial banking operations stage by stage maintaining construction financing as its core business.

In September 2000 CBB is converted to share company in accordance with the Ethiopian Commercial Code with a capital of Birr 79.0 million.

CBB's mission is to render long-term loans for residential and commercial buildings, medium and short-term loans and all other domestic and international banking services by deploying honest and motivated staff and employing state-of-the-art technologies and thereby meet the interest of all stakeholders.
