The recent tightening of credit we have seen in China is primarily aimed at clamping down on shadow financing. Wealth management products have rapidly grown in size, from only 8% of total banking deposits in 2012 to over 20% today.

The top chart shows China's banks' claims on non-banks, which is where a lot of shadow financing shows up. As we can see, growth in this category has fallen precipitously from 70% YoY to 20% today.

However, there is collateral damage from this tightening. For one, bank-lending rates are starting to rise as their cost of funding rises (bottom-left chart). Policymakers in China want to confine the rise in rates in to the interbank market, but this a next-to-impossible task. Too great a rise in lending rates would feed negatively into the real economy.
