The agency said the scale of credit was so extreme that the country would find it very hard to grow its way out of the excesses as in past episodes, implying tougher times ahead.
“The credit-driven growth model is clearly falling apart. This could feed into a massive over-capacity problem, and potentially into a Japanese-style deflation,” said Charlene Chu, the agency’s senior director in Beijing.
“There is no transparency in the shadow banking system, and systemic risk is rising. We have no idea who the borrowers are, who the lenders are, and what the quality of assets is, and this undermines signalling,” she told The Daily Telegraph.
While the non-performing loan rate of the banks may look benign at just 1pc, this has become irrelevant as trusts, wealth-management funds, offshore vehicles and other forms of irregular lending make up over half of all new credit. “It means nothing if you can off-load any bad asset you want. A lot of the banking exposure to property is not booked as property,” she said.
Concerns are rising after a string of upsets in Quingdao, Ordos, Jilin and elsewhere, in so-called trust products, a $1.4 trillion (£0.9 trillion) segment of the shadow banking system.
Bank Everbright defaulted on an interbank loan 10 days ago amid wild spikes in short-term “Shibor” borrowing rates, a sign that liquidity has suddenly dried up. “Typically stress starts in the periphery and moves to the core, and that is what we are already seeing with defaults in trust products,” she said.
