London-based Mr Hillery has been promoted from deputy CEO of the region, a post he took up last year, and will now co-lead the division with Matthieu Wiltz. He will retain his role as head of investment banking in EMEA.

Often referred to as one of the most senior Irish bankers in the world, Mr Hillery has been with JP Morgan since it bought the stockbroker Cazenove outright in 2010.

He is a son of Brian Hillery, the former TD and senator, who was a founding chairman of Providence Resources, and served on the boards of the Central Bank and Independent News & Media. Conor Hillery is a grand nephew of Patrick Hillery, who served as the sixth president of Ireland from 1976 to 1990.

Conor Hillery’s mother is Miriam Davy, the daughter of Eugene Davy, who won 34 international caps for the Irish rugby team and was one of the founders of Davy’s stockbrokers.

A commerce graduate from UCD, Mr Hillery trained as a chartered accountant with KPMG and first joined the investment bank Kleinwort Benson, before moving to Cazenove in 2002. He was promoted to head of UK investment bank at JP Morgan in 2013, and to its EMEA division in 2020.

Making today’s announcement, JP Morgan said: “Conor and Matthieu have served as deputy CEOs for the region since May 2024, focusing on our client franchises and working closely with our senior country officers to foster greater collaboration across borders and across lines of business.

“They succeed Filippo Gori, who was appointed CEO of EMEA and co-head of Global Banking in February 2024. With Filippo’s relocation to New York now complete, and given the time the GB business requires of him, he felt it was the right time to make this transition.”

“Together, Conor and Matthieu bring nearly five decades of experience at JP Morgan, and they are unwavering champions of our culture. Their combined roles in banking and markets provide a unique blend of industry expertise, market knowledge and client perspectives across important pillars of our company.”

Bloomberg has reported that the investment bank has a plan to increase revenue in the EMEA region by almost 20pc by the end of the decade.
