NEW YORK/LONDON, June 26 (Reuters) -

Citigroup's ( C/PN ) head of risk data, analytics, reporting and tech

Peter Cai has left the bank, a spokesman confirmed.

The departure has been announced internally on Tuesday but

the bank has yet to appoint an executive to replace him.

Cai was recently more focused on risk data analytics and

reporting, and responsibility for data remediation was shifted

in early 2023 from his division to a specific new team,

according to one source with knowledge of the matter.

Cai did not reply to messages to his Linkedin profile

asking for comment. The bank, that declined to comment beyond

confirming the departure of Cai, a former Barclays executive and

Carnegie Mellon professor, who was at Citigroup ( C/PN ) since 2019.

Last week, regulators increased the level of concern

with Citigroup's ( C/PN ) resolution plan, classifying its so-called

"living will" as deficient.

In a letter to Citi, regulators said weaknesses in its data

and controls contributed to inaccurate calculations of the

liquidity and capital needed to unwind derivatives positions.

They also asked for "independent confirmation" by next year that

the issues are addressed.
