Who can access your bank records?

Could you please elaborate on who exactly has the authority to access my bank records? Is it solely limited to the bank employees, or could there be other entities, such as government agencies or law enforcement, that might request access? Additionally, what safeguards are in place to ensure that my personal financial information is kept confidential and secure from unauthorized access? It's crucial to understand the extent of accessibility and the measures taken to protect my privacy when it comes to my bank records.
