Macro hedge fund Brevan Howard Asset Management had one of its best ever trading days on 4 February, according to a report by Bloomberg.

The firm benefitted from bets on short-term euro rates after the ECB signalled that it may begin to start raising interest rates this year. Star trader Fash Golchin who chalked up record losses last year, is said to have made 8 per cent, according to unnamed sources.

The firm's multi-trader Alpha Strategies platform, plus several other managers including Louis Basger, Minal Bathwal and Alfredo Siatta, are also said to have made gains.
