A number of senior equity derivatives staffers at Morgan Stanley have emerged as the latest casualties of the US investment bank restructuring, which is taking place across markets and divisions.

The departures in the equity derivatives and structured products business include the head of equity derivatives structuring in Japan, Christian Pemberton; the executive director for equity derivatives structuring in London, Guido Rizzato; the head of ETF trading in New York, Sanjay Chablaney; and  senior exotic equity derivatives trader, Andreas Aigner.

Also gone from Morgan Stanley are Pascal Baup, who looked after corporate equity derivatives for France, and Ben Shaker, who was responsible for corporate equity derivatives for Germany.

The news comes after the recent high-profile departures of the global head of corporate equity derivatives in London, Daniel Palmer, and the co-head of equity-linked capital markets for the US, Brian Lehman. The exits were part of the reduction in the US investment bank's headcount by 1,600 across all its divisions and locations, including equity derivatives, amid rumours that its Matrix trading platform could be put up for sale.

Kevin Woodruff, head of the global financial engineering group at Morgan Stanley in London, declined to comment on any of the staff changes.

The departures came at almost the same time as the bank's appointment of 144 new managing directors across all divisions.
