Some facts via Economist:
Problem loans have doubled in two years and, officially, are already 5.5% of banks’ total lending. The reality is grimmer. Roughly two-fifths of new debt is swallowed by interest on existing loans; in 2014, 16% of the 1,000 biggest Chinese firms owed more in interest than they earned before tax.
China is the world’s second-biggest economy; its banking sector is the biggest, with assets equivalent to 40% of global GDP. Its stockmarkets, even after last year’s crash, are together worth $6 trillion, second only to America’s. And its bond market, at $7.5 trillion, is the world’s third-biggest and growing fast.
In the past year alone, China has spent nearly $200 billion to prop up the stockmarket; $65 billion of bank loans have gone bad; financial frauds have cost investors at least $20 billion; and $600 billion of capital has left the country.
Hungry for profits in a slowing economy, plenty of Chinese banks have mis-categorised risky loans as investments to dodge scrutiny and lessen capital requirements. These shadow loans were worth roughly 16% of standard loans in mid-2015, up from just 4% in 2012. The second risk is liquidity. The banks have become ever more reliant on “wealth management products”, whereby they pay higher rates for what are, in effect, short-term deposits and put them into longer-term assets. For years China restricted bank loans to less than 75% of their deposit base, ensuring that they had plenty of cash in reserve. Now the real level is nearing 100%, a threshold where a sudden shortage in funding—the classic precursor to banking crises—is well within the realm of possibility. Midsized banks have been the most active in expanding; they are the place to look for sudden trouble.
