This document summarizes Thomas Fu's summer research project stress testing China's banking system. It finds that total credit in China's financial system has grown significantly since 2008, with shadow banking growing the fastest. Total credit is now over 200% of GDP, exceeding levels seen before most past banking crises. The rapid credit growth has been driven by real estate lending and loans to overcapacity sectors. This high and rising debt raises concerns about China's financial stability if credit growth slows or interest rates rise.
