Mark Mason, one of Wall Street's most prominent Black executives and a nearly 25-year veteran of Citigroup, has formally departed his role as the bank's chief financial officer, a role he had held since 2019. His exit, effective in early March, has been followed by a Wall Street Journal profile in which Mason made clear he wants his next job to be chief executive.
A CAREER FORGED IN CRISIS
Mason, 56, joined Citigroup in 2001 and ran Citi Private Bank and Citi Holdings before becoming chief financial officer in 2019. He was also CFO of the Institutional Clients Group; Citi Holdings was the unit that wound down the bank's unwanted assets after the financial crisis.
Mason was a key figure in the reorganisation Citi launched under Fraser in 2023, in which the bank set out to simplify its structure, cut 20,000 jobs by 2026 and modernise its technology to free itself from two 2020 consent orders.
GONZALO LUCHETTI TAKES THE REINS
The succession plan, announced in November 2025, elevated Gonzalo Luchetti, who had been leading Citigroup's U.S. personal banking division, to the CFO position. Luchetti, who previously ran Citi's consumer bank in Asia and EMEA and served as global head of wealth management and insurance, took over as CFO in early March.
Mason, meanwhile, has transitioned to the role of executive vice chair and senior executive adviser to Fraser, in which he is helping Citi prepare for its 7 May investor day and advising on strategic initiatives. The Wall Street Journal reported on 18 March that Mason has made clear he wants to be a chief executive; recruiters quoted in the profile said he would probably have to move to a smaller company to get the top job.
CEO AMBITIONS
Banking Dive has described Mason as arguably the highest-profile Black executive at a US-based global systemically important bank. He turned down the top job at Carlyle Group in 2023.
CITIGROUP'S PATH FORWARD
Citi will hold an investor day on 7 May, when Fraser has said the bank will lay out its plans to further grow its returns.
Citi has said Mason intends to pursue leadership opportunities outside the bank by the end of 2026.
