4. It doesn't make much sense for you to understand the relationship between Lehman and AIG. The reason for the collapse of Lehman is that e to the continuous escalation of subprime mortgage crisis, asset prices in the United States have shrunk significantly. And Lehman Brothers is an investment bank. They have invested a lot in real estate. At present, they have made huge losses in their investments. Many investors have begun to abandon their shares and bonds in the face of quarterly financial reports. If people believe that a bank will go bankrupt, it will go bankrupt, because everyone runs on it. If it doesn't go bankrupt, it will go bankrupt. This is obvious when it is believed that Lehman is unable to cope with the asset shrinkage caused by subprime lending (especially when it holds a considerable amount of real estate investment). In the United States, unlike China, commercial banks have a mandatory ratio of deposits to reserves. Even if Lehman is worth $1 trillion, it's not worth a cent when its reserves in circulation are run out of business. This is the root cause of the collapse of Lehman. The subprime mortgage crisis is simple: the real estate market in the United States was low in the 1990s. Because the house purchase loan has the real estate as the mortgage, the bank has launched the sub-prime credit loan, that is, the house purchase loan does not need the credit evaluation. As a result, the property market has recovered. Next, many banks packaged these subprime loans into securities, listed them, and then obtained funds to make new investments. This has planted a hidden danger for the subprime crisis. After 2004, the U.S. housing market continued to decline, and in the summer of 2007, it was out of control. Many of the original subprime mortgage buyers feel that the house is cheaper than the loan, so they simply don't pay it back. This led to a large-scale sell-off of bank subprime bonds in the market. On the one hand, subprime investors (there are many commercial banks) have suffered huge losses. On the one hand, the bank's cash out of the subprime mortgage has been transferred to other uses and is unable to redeem. And financial institutions cross shareholding each other, which led to a series of economic crises. The real estate market plummeted - the subprime mortgage sold badly - the bank liquidity was seriously insufficient - the investors lost money, closed their positions and held money... The problem came
