Rocky geopolitics are sure to drive global markets in 2016, Peter Oppenheimer, chief global equity strategist at Goldman Sachs, said Wednesday.
"Political uncertainty at one level or another is one of the risks that we see of being quite high through the year, and that should be reflected quite high in risky premium and risky assets," Oppenheimer told CNBC's "Worldwide Exchange."
"The main view that we've had for this year is one of quite high volatility," he added.
He described his outlook for European equity markets as "fat and flat," with a broad trading range but relatively low returns.
Oppenheimer also pointed to China's pervasive effect on global markets, where wild swings in Chinese trading pushed markets in Asia lower this week.
