A more thorough explanation:

A bank examiner is a government official who checks on banks to make sure they are financially stable and following the rules. They look at things like how much money the bank has, how it is being managed, and what policies it has in place.

For example, if a bank is lending too much money to people who might not be able to pay it back, a bank examiner might notice this and tell the bank to change its policies. Or if a bank is not keeping enough money in reserve to cover unexpected losses, a bank examiner might require the bank to increase its reserves.

Overall, bank examiners help to make sure that banks are safe and trustworthy places to keep your money.
