The extent of the Chinese share market collapse is now testing the ability of Beijing to moderate the "invisible hand of the market" by the "visible hand of Government".
Chinese regulators yesterday blamed "panic sentiment" and "irrational sell-offs" for the plunging share markets which have led to trading halts being called on nearly 3000 companies.
But the more fundamental question is whether it is rational to expect Chinese Government measures - like suspending IPOs and making it easier for investors to meet margin calls - will bring an end to the current instability.
The market reaction has posed a major challenge for President Xi Jinping. When questioned on whether the Chinese Government could work the switch to a more true free market environment without ensuing chaos, Xi has expressed confidence in his Government's visible hand to moderate the market's invisible one.
