As UK CEO, Yeats will be responsible for the direction and leadership of the business, the firm said in a statement. He joined State Street in 2007 and has extensive experience in asset management and an understanding of the UK investment management landscape.

Currently, Yeats serves as global head of systematic fixed income for State Street IM. He will continue in this role alongside his new responsibilities, overseeing a team of investment professionals globally who manage more than $700 billion in fixed income solutions. He has also served as UK head of investments for the firm.

Yeats will succeed Alex Castle as the firm’s UK CEO, after the latter’s departure from State Street IM at the end of September 2025. He will report to Ann Prendergast, head of EMEA for State Street IM.

“Stephen has an extensive track record and vast experience, covering our firm specifically and the wider sector alike, which made him an ideal candidate for this role,” Ann Prendergast, head of EMEA at State Street Investment Management, said.
