Reports say his driver was killed by the two attackers, who then fled.
Interfax, quoting sources close to the investigation, said the attack appeared to be an attempted contract killing.
The attack on Kozlov, 41, took place as he arrived at a sports stadium to watch a soccer match.
Under Kozlov's supervision, the Central Bank canceled the licenses of a large number of banks that were suspected of involvement in money laundering.
