PT Bank Mandiri (Persero) Tbk

Budi Sadikin is one of the strongest supporters of reform in Indonesia's banking industry. The CEO of the state-owned Bank Mandiri, who was formerly a manager at IBM's Tokyo headquarters, has been very vocal since financial regulators recently postponed Mandiri's acquisition plan of a smaller state-owned lender. He argues that Indonesia, which has 120 banks, should follow the path of Malaysia, which recently began a three-way merger to form the country's largest lender.

Sadikin's stance shows the power the government holds in decision making. While 40% of its shares are available to the public, Bank Mandiri, like many other state-owned enterprises, requires government approval for every proposal made at the bank's shareholders meetings.

Bank Mandiri was created in 1999 from the merger of four banks under a government restructuring effort after the Asian currency crisis. It went public in 2003 and is currently the country's largest bank by assets. It offers one-stop financial services, including brokerage services, asset management, insurance and Islamic finance.
