# 1920 – On November 15, the Banca d'Italia opened a branch at Mogadishu.

After the unification, National and Grindlays opened a branch in Mogadishu.

# 1960 – On July 1, 1960, the newly independent Republic of Somalia established the Banca Nazionale Somala (National Bank of Somalia) to take over the activities of the Cassa per la Circulazione Monetaria della Somali and the Mogadishu branch of Banca d'Italia.

The government also established the Somali Savings and Credit Bank to take over the commercial branches of Banca Nazionale Somala, leaving the Banca Nazionale Somale with only central banking functions. The Somali Savings and Credit Bank had branches in Baidoa, Beledweyne, Berbera, Bosaso, Burco, Galkacyo, Qardho, Hargeisa and Kismayo, and for a while in Djibouti.
# 1975 – On February 8, the government renamed the Banca Nazionale Somala to the Central Bank of Somalia (Bankiga Dhexe ee Soomaaliya). It also merged the Somali Commercial Bank and Somali Savings and Credit Bank to form the Commercial and Savings Bank of Somalia, which was at the time the only bank in the country.
