Russell Investments chief investment officer for the Asia-Pacific Peter Gunning has been elevated to the job of global CIO.
Based in the United States, Gunning, who has worked for Russell for 12 years, will manage a team of 300 investment professionals across the firm's global offices.
He will report to Russell president and chief executive Craig Ueland.
The Australian team will still report to Gunning while he moves into the global role.
"This new role is a great opportunity for Pete as well as for the Australian business and our clients," Russell managing director Alan Schoenheimer said.
Gunning's promotion is the second major staff change in a year for Russell.
In January, it lost its managing director of institutional investment services Stephen Roberts, who had worked with the firm for six-and-a-half years.
