KB Financial Group's chair nomination committee on Sept. 11 named former KB Kookmin Bank president Lee Jae-keun as the sole candidate for the group's next chairman. Incumbent chairman Yang Jong-hee, who had sought a second term, was excluded from the final shortlist.

It is unusual for an incumbent's renewal to fail in a financial holding company chair selection. Convention has been that a term without major deficiencies in performance or organizational stability leads to renewal, so the decision was read in the market as an upset.

Lee, the nominated former bank president, is regarded as having covered both group finance and retail banking operations. The chairmanship is confirmed after board approval and a shareholder meeting.

Pressure across the sector to improve governance is cited as background. Supervisors have for several years reviewed the transparency of chair selection and the management of candidate pools, and holding companies have been revising succession programs.

Industry figures expect the decision to affect succession timetables at other groups. Once a precedent exists that renewal is not automatic, candidate-pool management and performance criteria tend to tighten.

Nothing changes immediately for customers. But a change at the top of a holding company often brings subsidiary leadership changes and reorganization, leaving year-end shifts in business strategy as the point to watch.
