It's official - everyone's involved! According to the 21st Century Business Herald, at least 17 financial institutions involved in copper, aluminum and other nonferrous metals financing business face losses of almost 15 billion Yuan (not including the contagious rehypothecated collateral chains involved) due to the over-invoicing of the Qingdao port. Crucially, it appears that the evaporation of collateral (i.e. multiple loans secured by the same collateral) has been confirmed officially and banks such as Standard Chartered have already ceased any new business via this supposedly secured channel.
