PANews reported on March 13 that according to Bloomberg, US macro hedge fund giant Brevan Howard Asset Management is drastically reducing the risks that traders can take amid declining performance and the evaporation of last year's earnings. According to people familiar with the matter, the company's CEO Aron Landy has recently taken some defensive measures in view of the increased market volatility and chaos, including reducing the risk limits of some traders. An investor letter showed that Brevan Howard's flagship fund Master Fund fell 1% in the first week of March, widening its losses so far this year to 5.4%, while the fund achieved a return of 5.1% last year; the company's other major fund Alpha Strategies also fell 0.8% that week and has risen 1.5% so far this year. Since Howard participated in the establishment of the fund in 2003, Brevan Howard's flagship fund has only suffered a loss of more than 5% in one year.

Global market volatility has increased in recent weeks as the Trump administration clashed with global trading partners, raising investor concerns about everything from tariffs on Canadian goods to increased defense spending in Europe. The turmoil has also affected hedge fund giants such as Citadel, Millennium Management and DE Shaw & Co.
