Their banks become secret hedge funds.
China's trust firms, with total assets of $2.2 trillion, and who together with Banker Acceptances comprise the bulk of China's shadow banking pipeline, and no longer able (or willing) to lend to China's small companies and individuals due to a spike in regulation, are shifting more cash into frothy capital markets and over-the-counter (OTC) instruments instead of loans.
In other words, instead of using their vast cash hoard of over $2 trillion to re-lend and stimulate China's economy, China's unregulated, shadow banking conduits are now directly buying stocks!
Yet another sign of their economy's increasing sclerosis.
This is about the maturity level I imagine actual politics happens on.
