Global macro hedge fund firm Rokos Capital Management has reported double digit losses for March as big market swings during the month, triggered by the banking crisis, hurt some, but not all, hedge fund returns, according to a report by Reuters.

A late month market rally helped equities strategies to small gains, according to investors and industry data.

An unnamed Reuters source familiar with the matter revealed that London-based Rokos ended the month down roughly 15%, taking year to date losses to nearly 9.5%, a sharp contrast to last year's 51% gain.

Other big-name funds fared better last month including Tiger Global, which posted a 5.2% gain in March, to take its return for the quarter to +7.3% on the back of large tech company gains.
