UBS’s Japan Investment Banking Chairman Matsui to Resign

UBS AG, Switzerland’s biggest bank, said Yasuki Matsui will resign as chairman of the investment banking division in Japan, becoming at least the third senior executive in the country to leave a European bank since October.

Matsui, who joined UBS in 2007 from Morgan Stanley as co-head of Japan investment banking, will leave on Dec. 31, Eiko Noda, a Tokyo-based spokeswoman, said today. She declined to comment on why he is leaving and whether the Zurich-based bank will replace him.
