Recent BlackRock arrival Peter Fisher has been made chairman of Blackrock's Asian businesses, where he will be responsible for execution of its strategies in Asia. As part of the new role, Fisher will direct new business development for both investment management and BlackRock solutions, while also overseeing local trading and potential portfolio management initiatives.

The job also sees Fisher acting as BlackRock's senior representative to regulatory authorities and local business communities.

He takes on the Asian role after most recently serving as a managing director and a member of BlackRock's management committee.

Outside of the US Treasury Department, Fisher spent 15 years with the Federal Reserve Bank of New York, where he ended with the title of executive vice president.

Also joining the firm in the region is Winnie Pun, who assumes the role of managing director with responsibility for leading BlackRock's account management activities in Asia ex-Japan from Hong Kong. Pun moves from State Street Global Advisors in Hong Kong, where she was principal and director of investments.

In Japan, the firm's operations remain in the hands of Hiro Arita, who will also continue leading its joint venture with Nomura Asset Management, Nomura BlackRock Asset Management.

Presently, BlackRock manages over $27 billion for Asia-based clients and provides risk analytics for Asian institutions through its risk management arm BlackRock Solutions.
