The position combines the role of chief information officer, which concerns technology, and group chief operating officer.
Harvey will take the role from October 1, drawing on 25 years of technology and operations experience.
The current chief operating officer David Hodgkinson will retire from the group on December 31 after working for the company for 39 years.
Michael Geoghegan, group chief executive of HSBC, says: “By combining our technology and worldwide operations more closely we can re-engineer customers’ experience of HSBC and at the same time drive down the unit cost of production.
“Harvey’s appointment to the group management board is a reflection of the importance we attach to realising these benefits for HSBC.”
He adds: “Hodgkinson’s international banking experience and wise counsel have been invaluable. He has been a good friend and colleague to many of us over his illustrious career with HSBC, and we wish him and his family well.”
