Financial risk -- especially the term "grey rhino" -- has been frequently referred to at this year's forum. In finance, a "grey rhino" refers to problems which could have a major negative impact on an economy and society in general, but they just don't receive the attention they deserve. Some panelists believe "debt" to be one of these, and Chinese policy-makers really need to sort this issue out as soon as possible.

BA SHUSONG MANAGING DIRECTOR, HONG KONG EXCHANGES & CLEARING LIMITED "The continuous rise of leverage is caused by the low return rate from the real economy. Looking back into China's history, fast credit growth didn't necessarily mean a high leverage rate. On the contrary, in periods where China witnessed a rapid growth of credit, the leverage rate remained low. Why? Because we had a high return from the real economy, that was enough to cover the cost of the debt. So, in the long term, if we want to lower the leverage, we have to find growth drivers in more areas."
