There is market support practiced by most countries financial authorities, usually with things such as circuit breakers, etc... but what the Chinese authorities have been doing is tantamount to meddling, acts of desperation, runs afoul of free market principles or proper capitalism.
Here are the things China has done for the past 10 days to stop the sell down:
1) drop interest rates by 75 basis points2) ban IPOs3) ask state own firms not to sell shares4) ask securities firms to buy shares (this one is so puzzling)5) allow companies who wish to suspend their own shares, for basically any reason ... now its close to 50% of all listed companies in China having requested and being suspended from trading6) restricted short bets on index futures
as if thats not enough, today they announce that anyone holding at least 5% shares in any listed company CANNOT sell their shares for 6 months.
BUT ... wait for it ... this one takes the cake ..."Under new rules announced last week by the country’s securities regulator, real estate has become an acceptable form of collateral for Chinese margin traders, who borrow money from securities firms to amplify their wagers on equities. That means if share prices fall enough, individual investors who pledge their homes could be at risk of losing them to a broker." To allow punters to literally bet the house on it ... soon securities firms will be the biggest house owners!!!
The ChinaSecurities Regulatory Commission has done more than what is deem proper in order to prop up the market. But markets are in panic mode and is fuelled mainly by passions and not rational thinking. Two things guide markets trend, FEAR & GREED. There is now too much panic and fear, and every additional step taken by CSRC are being viewed of acts of desperation and add fuel to fear.
The cascading effects of China's correction lies not with just punters betting on the markets but rather companies themselves using their shares as collateral for margin lines to play the market themselves. Much of the funds has gone to manipulate, support or push their own share prices higher, and/or bet on other companies. The cascading effect is due to margin facilities being cut, stop or collateral being sold down.
However when you can willy nilly suspend your counter to evade a sell down, the selling can only build up, not abate.China isn’t the only market with a history of state intervention. During the Asian financial crisis in 1998, Hong Kong’s government bought shares worth $15 billion to prop up the market. In the U.S., the Securities and Exchange Commission temporarily banned short selling on some shares during the global financial crisis in 2008.
Xi Jinpeng has a bigger vested interest to prop up the markets. Thanks to his anti corruption drive, and a deliberate move to divert hot money from property, he has fast tracked the popular HK Connect which allows China investors to buy HK shares and vice versa. In a way, its also a good way to channel hot or laundered money out of the country. This was seen as an OK signal from the government to the public that its OK to buy shares. The anticipation that the HK Connect train would also apply to Shenzhen shares soon cause massive speculation especially in Shenzhen's already frothy and more speculative market.
The Grexit situation was a good reason for some big players to start taking chips off the table, what was unexepected was the domino effect and the many banks and financial firms holding collateral shares acted first, to start the dump rolling. With foreign investors exiting as they regard more and more intervention sound like a really iffy stock market place - they sold and sold with little intention to come back anytime soon.
Lessons here - recognise bubble when it is bubbling. Central banks must make sure banks are well capitalised and their exposure have limited consequences. Margin limits must be enforced religiously. Then bubbles will still burst, but we want to minimise the downside effects as much as we can.
Welcome to the world of capitalism. Live and learn.
Someone twitted to us during our BFM show about the veracity of the figures of a country's stock market as a percentage of GDP. Why is the figure important ... if you can strip out foreign listings and non related listings (inclusive of SPACs) and maybe some REITs that are foreign or regional in nature, you get a good grasp of how much of your economy is listed. 
The higher the figure, the higher the importance of the stockmarket in feeling and shrinking economic activity. IN a super bull, Malaysian domestic economy would flourish as most people will see a lot of funds swishing around, the same when its a bear market when restaurants business dwindles sharply. The higher the figure, the more attention will the central banks and authorities pay to major fluctuations in share markets.
