"How they come out in the next few days is going to really drive the direction in which risk will go," Lagarde said.
The financial markets did not panic Friday after the vote, Lagarde said. She said central bankers put a lot of liquidity into the markets so there wouldn't be a shortage, as happened during other market plunges, including in 2008.
