What describes the purpose of insufficient funds fees?

Insufficient funds fees, often referred to as overdraft fees, are charged by banks when a customer attempts to withdraw more money than is available in their account. The purpose of these fees is to cover the bank's risk of loss when it honors a transaction despite insufficient funds. Additionally, these fees serve as a deterrent against reckless spending, encouraging account holders to maintain sufficient balances. Ultimately, they aim to promote responsible banking behavior while allowing banks to recover costs associated with processing these transactions.
