The Central Bank of Oman (CBO, Arabic: البنك المركزي العماني) was established in December 1974 and began operations on 1 April 1975. It replaced the Oman Currency Board as the principal currency authority in Oman. Currently it is headed by Taimur bin Asaad bin Tariq al-Saeed. The Sultanate has made significant progress in implementing the new capital Adequacy criteria laid down in the Basel-II Accord. The adoption of Basel II would transform the current approaches and tools of supervision of the CBO as well as the audit and risk management practices of banks.
