Risks to China's banking system from the bond market in China. China's bond market has grown rapidly to 25.5 trillion yuan or $4.1 trillion yuan, especialy in the period following the stimulus. But it is not similiar to bond markets in developed countries, the U.S., Japan and France. It has a patchwork of regulators, is closed to foreign investors, and does not offer protections to investors. It also lacks an effective ratings system. Most bonds are held and traded by the banks, which concentrates the risks in the banking system. In developed countries the risks are spread out among investors. Bond markets offer the advantage of reducing dependence on banks for lending but with banks holding most of the bonds in China, including that of local governments, the risks if bond issuers default are concentrated in the banking system.
