I think for China, it depends on the the price of housing market, cpi, interest rate, the balance of total mortgage over the total commercial loan. rmbs and cds are not sufficiently developed in emerging market. Initially, they can spread risk rather than creat risk. Unless they escalate into betting,would not be the sin of the crisis. Thus, in China, currently you don't have to consider too much on the rmbs and cds risk.housing bubble and interest rate and related government policies are the keys.
