Standard Chartered Bank’s co-head of prime services Andrew Sterry has left the firm after nine years.

Sterry, who joined the British bank from Citigroup in 2013, left Standard Chartered last month, according to sources close to the firm.

A spokesman for Standard Chartered Bank confirmed Sterry’s departure.

Sterry has been Standard Chartered Bank’s London-based managing director and co-head of prime services since he was hired in mid-2013 to build the group’s prime division from the ground up.

He has managed over nine years the growth of the Standard Chartered Bank prime services business to offer prime services in London, Singapore, Kuala Lumpur, Bangalore and New York, employing more than 50 staff.

Sterry joined Standard Chartered Bank in 2013 from Citigroup where he was the US bank’s global head of over-the-counter central clearing product strategy. He joined Citi in late 2009 to set-up the US bank’s European over-the-counter clearing service before assuming responsibility for global product strategy in 2012.

Before Citi, Sterry worked for 18 months Ravenscourt Capital Partners, an investment firm, and for eight years at Lehman Brothers where he was an executive director in derivatives and fixed income brokerage.

He began his career at Deutsche Bank in over-the-counter derivatives.

Standard Chartered’s global head of securities lending financing & securities services Sunil Daswani said in March that business has seen a “healthy and strong” influx of clients and prospects over the last year.

In January, Standard Chartered appointed Marisa Drew as its new chief sustainability officer and Roel Louwhoff as chief technology, operations and transformation officer, effective April 1.
