Run is a Chinese vocabulary, its basic meaning refers to the phenomenon that in the financial field, a large number of depositors withdraw cash from banks at the same time, resulting in insufficient bank reserves and unable to meet the needs of all depositors, thus triggering a bank payment crisis. This phenomenon usually occurs when banks face a credit crisis or when the market fluctuates greatly.

The direct consequence of bank run is that banks face serious liquidity risks, which may lead to the failure of normal operation or even bankruptcy of banks. In order to prevent bank runs, governments and financial regulators usually take a series of measures, such as establishing deposit insurance system, strengthening bank risk management and improving information transparency. At the same time, depositors need to be rational when dealing with financial risks, and avoid blindly following the trend and causing unnecessary losses.
