One. Large overdue
For those large banks, it is basically difficult for them to fail. If all fail, it is basically time for a financial crisis. Just like the subprime mortgage crisis in the United States in 2008, a large number of people borrowed money to buy a house, but later, because of the decline in house prices, many people did not pay back the money directly. If the money lent by the bank can't be recovered, then the bank will definitely go bankrupt. Not only can the lent money not be recovered, but it will also cause people who save money here to want their money back.
Two. illegal act
There are some small banks, and they may do some illegal acts to make profits. If any bank commits a particularly serious illegal act, it is likely to be directly ordered to close by the state. If it's just some common minor violations, then punishment measures will usually be taken to close it down.
No one saves money
Some people will build their own banks, but few of them will save money. If the bank says that no one saves money, then naturally there is no money to lend. After a long time, they have no money to operate and will naturally go bankrupt.
