Financial products still remain complex

Zhu Min, deputy managing director of the International Monetary Fund, is also attending the World Economic Forum in Davos. He says that financial products still remain complex and regulators around the world need to cooperate more closely to fend off potential risks.

He said, "The financial sector still accounts for 36.6 percent of GDP. I mean banking adds equity markets adds bonds roughly. Still too big. Leverage ratios still way high. Our say, the whole financial sector still has a long way to go."
