Rokos Capital Management, the hedge fund run by billionaire investor Chris Rokos, is looking to raise up to $3 billion in fresh capital on the back of record gains for its global macro fund, according to a report by Bloomberg.

The report cites unnamed sources as saying that the London-based investment firm, which currently runs about $51.5 billion, has already held talks with potential new clients, and existing investors looking to reinvest their gains.

Rokos is reportedly looking to raise the extra cash as the is counterparties require the firm to post higher margin due to ongoing market volatility.

Rokos is among a group of macro traders that have benefitted from rising volatility and interest rate hikes this year which has seen them notch up big gains. The firm is on track to post record its best ever annual returns this year having put on 45% in the year to the end of November generating $5 billion in profit.
