In 2016, five FDIC insured banks failed. This was the lowest level since 2007.The late 1980s bank failures were caused by corruption and control fraud.
Most of the great recession / housing bust / financial crisis related failures are behind us.
The first graph shows the number of bank failures per year since the FDIC was founded in 1933.
The second graph includes pre-FDIC failures. In a typical year - before the Depression - 500 banks would fail and the depositors would lose a large portion of their savings.
The 1990s bank failures would have been far larger if we hadn't bailed them all out.
Pre FDIC is just f%$#ing scary.
