Guang Niu/Getty ImagesCorporate debt in China has soared to $18 trillion, or 169% of GDP, the largest pile of corporate debt in the world, according to the worried Bank for International Settlements. The OECD has warned about it earlier this year. The New York Fed warned about this debt boom in February and that it could lead to a “financial crisis,” but that authorities have many tools to control it. The IMF regularly warns about China’s corporate debt, broken-record-like, and did so again a few days ago, lambasting the authorities for their reluctance to tamp down on the growth of debt.
