J.P. Morgan Taps Former Citi Deal-Maker Anthony Diamandakis to Boost Ties with Asset Managers

J.P. Morgan has appointed veteran banker Anthony Diamandakis as vice chair of its Strategic Investors Group, aiming to deepen relationships with key financial sponsors and asset managers. The move signals the bank’s intensified focus on major institutional investors such as private equity firms, sovereign wealth funds, and family offices—entities that command trillions in deployable capital and are behind many of the world's largest deals.

Diamandakis brings over two decades of investment banking experience, including nearly 11 years at Citigroup, where he was a prominent figure in deal-making, and a 17-year tenure at Credit Suisse. His extensive background aligns with J.P. Morgan’s strategic push to expand influence and service offerings for clients in the global financial sponsor space.

According to a memo reviewed by Reuters, Diamandakis will report directly to Avery Whidden, global head of J.P. Morgan’s infrastructure and Strategic Investors Group. The hire reinforces the firm’s intent to strengthen its position in advising and partnering with high-impact capital providers.

This leadership addition comes as competition intensifies among global investment banks to attract and retain the business of financial sponsors, who are increasingly shaping M&A activity and capital markets trends. By bringing on an industry veteran with deep sponsor relationships, J.P. Morgan positions itself to capture more deal flow and advisory mandates in this influential segment.

J.P. Morgan continues to enhance its leadership bench with experienced professionals to stay competitive in a rapidly evolving financial landscape. Diamandakis’ appointment reflects the bank’s commitment to cultivating long-term partnerships with top-tier institutional investors, as they remain central to driving large-scale transactions across markets.
