Hans Schuettler, Morgan Stanley's chief executive for Asia, has resigned less than two years after his appointment in April 2006. He is returning from Hong Kong to Germany. Morgan Stanley Asia chairman, Stephen Roach, who has been with the Wall Street bank since 1982, becomes acting chief executive for Asia. "Hans and the senior team have done a tremendous job. We've seen significant growth in our Asia footprint and achieved record performances across all business lines,” said Mr Roach, referring to the sales and trading, banking, asset management and private wealth divisions.
