Bank of Khartoum (BOK), is the largest bank in Sudan. With some 111 or more branches, it is also the commercial bank with the oldest continuous history in the country. The largest single shareholder is Dubai Islamic Bank. In 2011 the government of the United States of America lifted its sanctions on Bank of Khartoum. The US Treasury’s Office of Foreign Assets Control posted notice on its website that it had removed Bank of Khartoum from the blacklist, meaning Bank of Khartoum could seek the return of blocked assets and resume limited dealings with U.S. financial institutions.
