Adds context behind the hires and details from paragraph 3

By Nell Mackenzie

LONDON, Sept 16 (Reuters) - Hedge fund Citadel said on Monday it has hired London-based portfolio managers for its Fixed Income and Macro business adding three new hires to start from November through next year.

The $63 billion hedge fund said it has hired Bernard Singer as a portfolio manager and Ravi Vinda, as an associate portfolio manager, both joining from hedge fund Brevan Howard. They will both start from mid-2025.

The investment manager also said in a statement it had hired Christine Boykiw as an associate portfolio manager who would take up her new role in November from UK bank, Barclays BARC.L.

The hires are a part of a broader push behind the hedge fund's bond and economic trading program, said a person familiar with the matter.

Two of the hires, Vinda and Boykiw will be part of Sam Finkelstein's portfolio development programme.

Reuters reported in February that Finkelstein had been hired from Goldman Sachs Asset Management to lead a programme in its fixed income and macro business for developing portfolio managers.

Citadel, unlike some multi-strategy hedge funds, does not work in so-called "pods" which are not allowed to communicate, but rather in teams collaboratively.

"Attracting exceptional talent and investing in their professional success has been a key driver of Citadel's long-term performance and we look forward to welcoming Bernard, Ravi and Christine to our growing fixed-income and macro team," the Citadel statement said.

Multi-managers such as Citadel have continued to expand headcount this year. Over the last 12 months, these hedge funds added an estimated roughly 2,400 new hires an increase of almost 15%, a note from Goldman Sachs said earlier this month.

The new hires were not immediately available for comment when contacted by Reuters.
