This morning the global markets were in a tail spin. Europe was trying to sell off its stock, U.S.'s stock is in the red, and China's stock is down 5%. There is a massive sell off of China's stock since the regulators are clamping down on traders. According to Business Insider, the Regulatory Commission in China has banned brokerages of the margin trading businesses from taking part in umbrella trusts and the Securities Association of China says fund managers can lend shares for short selling. To put it simply, margin trading is with borrowed money, so banning this type of trading will mean less liquidity for some accounts. Which means it is harder to buy stock in China, but easier to bet against them. After this fall in stock markets around China are feeling the pain as well. In Hong Kong, the stock is down 5.9% and in Europe there is a massive selling off of stock, German and French stocks are down 1.4% and Spain and Italy are down by 2%. Also the ticking time bomb of Greece and their central bank, which has huge debts and is tied to many other central banks in Europe, stock is down to zero. China's stock market was one of the best in the world in the past few years, but this morning it seems like those days might be gone. A year ago, their stock was up 32% and now there are huge sell offs.
