In his new role, he will represent the interests of Qatar’s royal family - a top shareholder of the German lender -, the sources said.
Zeltner, a former head of UBS Wealth Management, was named earlier this year as the chief executive officer of KBL European Private Bankers (KBL epb), which is controlled by the Al-Thani family of Qatar.
The family also owns 6.1% of Deutsche and is among Deutsche’s largest shareholders.
Zeltner is expected to replace Richard Meddings, who is leaving the board.
Qatar’s previous pick for the supervisory board, Stefan Simon, recently moved to Deutsche Bank management.
Bloomberg first reported the news.
