JP Morgan Asset Management plans to increase its international staff in private banking by a third this year in response to rapid growth overseas, with particular focus on the high net worth segment, chief executive Mary Erdoes said Tuesday.

Speaking at a JP Morgan investor day, Erdoes said client advisors in private banking grew from 2,310 to 2,600 last year, as its overseas operations expanded. "International staff in private banking grew by 32% last year and that will happen again in 2011 with the total private banking staff growing by 9%," she said.
