Gennady Melikyan, head of the Main Inspectorate for Credit Institutions, will assume the post formerly held by Andrei Kozlov.
Melikyan, 58, is a deputy chairman of the Central Bank, and has a seat on the board of directors. He was formerly Russia's minister of labor, and was a deputy chairman of the country's state-run savings bank, Sberbank, until 2003.
Kozlov, 41, died on the morning of September 14 after gunmen opened fire on him with semi-automatic weapons the previous evening. Kozlov's driver was also killed in the attack.
He oversaw the Central Bank's efforts to clean up the banking sector, and was shot in an attack that bears the hallmarks of a contract killing as he left a sports stadium in the northeastern Moscow district of Sokolniki.
Kozlov led efforts to close down dozens of banks for violations of banking legislation, particularly on money laundering, and Central Bank regulations. Two high-profile cases centered on the revocation of licenses from Moscow-based Sodbiznesbank in 2004 and Neftyanoi Bank this year, but the CBR has been withdrawing licenses almost by the week in 2006.
