The private banking arm of Credit Suisse has seen the resignation of Paul Sarosy, its head of UK domestic clients.

Sarosy has been replaced by Eric Pfister, head of market area UK/international, on an interim basis.

Zurich-based Pfister, who divides his time between Switzerland and London, has been in role for only a few months, having previously been head of international markets at Clariden Leu (the legal integration of the private bank into Credit Suisse was completed in April). Earlier in his career Pfister was head of business support, private banking chief operating officer at Credit Suisse for three years and before that between 2003 and 2005 he led the Asia Switzerland unit at Credit Suisse.

Sarosy joined Credit Suisse as managing director and head of investment solutions for the private banking business in the UK in the summer of 2007. He previously worked at Merrill Lynch’s private client business, where he had been responsible for all sales activities in EMEA across transactional and annuitised products, as well as product development. Details of his next role have yet to emerge. (To read an interview in late-March with Sarosy by this publication, click here.)

In other news at the Swiss banking giant, today has seen Credit Suisse’s name emerge among the banks said to be trying to buy the non-US wealth management businesses of Bank of America Merrill Lynch in a deal that could be worth around $2 billion.

According to a Reuters report, citing unnamed sources, Royal Bank of Canada and Zurich-listed Julius Baer are also among the potential suitors.

BoA has reportedly put its non-US wealth business up for sale - which includes units in Asia excluding Japan, Europe and the Middle East and Latin America. Analysts have told WealthBriefing that such a transaction would make sense as BoA, which acquired Merrill Lynch in 2009, has failed to achieve critical mass in its non-US wealth business in recent years.

Bank of America’s non-US business manages about $90 billion of an estimated $2 trillion that the BoA wealth division oversees globally, as the news service reported.

Some earlier estimates had put the deal value at as much as $3 billion, though sources said this week that a $1.5 billion-$2 billion price tag may be more realistic, the news service said.

The first round bids closed earlier this month and Bank of America is in the process of notifying the shortlisted bidders, it added.

Julius Baer, Credit Suisse and Royal Bank of Canada have declined to comment, as has Bank of America.
