WATCH: Adjust expectations of returns after Brexit - economist

Cape Town - The key fundamental thing to remember in the post Brexit vote world is that investment returns are going to be lower, according to Rian le Roux, chief economist of the Old Mutual Investment Group.

"One thing we have seen after the Brexit announcement is a lot of volatility in the markets. I think what Brexit means over the longer term is a world economy that is struggling," he explained.

"And a slow growing world means relatively low investment returns, which means people have to save more."
