JPMorgan Chase & Co. has created the position of global head of its private bank and appointed veteran executive David Frame to the post, according to a Wall Street Journal report. The move is part of a broader overhaul aimed at better serving ultra-high-net-worth clients who typically keep at least $10 million with the firm. The restructuring will shift the private bank’s focus toward helping clients diversify more of their wealth outside the United States. Frame, who previously ran JPMorgan’s U.S. private-bank business, will oversee relationship managers and investment specialists worldwide as the bank seeks to capture faster growth in cross-border portfolio flows.
