A prominent Citigroup executive is leaving as the bank reorganizes an elite arm of its wealth management business, the latest shift in a series of significant structural and leadership changes at Citi in recent years.

Citigroup Inc. is revamping the management structure of its private bank following the resignation of Ida Liu, who’s led the unit for almost four years.

Ida Liu, an 18-year veteran of the bank, did not detail her future. Citi eliminated her post and will instead have four regional private-banking chiefs.

The megabank is simplifying the management structure of its private bank. Regional leaders will now report directly to Andy Sieg, head of wealth.

Ida Liu, who had been the global head of Citi Private Bank since April 2021, made the announcement on LinkedIn.
