SEOUL-- The new chief executive of Shinhan Bank has offered to resign due to an unspecified health issue only about a month after being elected to the top post of the major South Korean lender, bank officials said Monday.

Shinhan Bank said its CEO Han Yong-gu, who assumed his post on Dec. 30, informed the bank of his decision to resign to minimize the impact from a management vacuum. He said he needs medical treatment, which could take a substantial amount of time.

Shinhan Financial Group plans to quickly hold a meeting to seek Han's successor.
