Global macro is the strategy of investing on a large scale around the world centered on economies, history, and international relations. The strategy is typically based on forecasts and analysis about interest rate trends, the general flow of funds, political changes, government policies, inter-government relations, and other broad systemic factors.

In the 2010 Opalesque Roundtable discussion of global macro, hedge fund manager John Burbank discussed the increasing importance and shift of private and institutional investors toward more global macro strategies.

Global macro trading strategies are based on educated guesses about the macroeconomic developments of the world. Mike Novogratz, former president of Fortress Investment Group, is a global investment management firm with total assets under management of approximately $41.6 billion and $4.3 billion in a global macrohedge fund in 2015 discussed global macro trading in his video interview. Novogratz described global macro strategies as monitoring these macroeconomic stories, such as global imbalances, business cycles, the survival of the Euro, and changing growth models of emerging economies. He says that there is an inherent difference between global macro fund managers and traditional equity managers. Most long/short equity managers started in research as analysts and look to follow these macroeconomic stories based on what positions they believe in and stock positions they rely on.
