Casey is right, when you look at your bank statement, the statement is shown from the perspective of the Bank. The money you deposit is a liability to the bank, therefore when you withdraw money their Liability is reducing hence a debit.

From the companies perspective, cash/bank a/c are an asset, hence the rule applies, i.e., 'An entry which increases an asset account is called a debit.' For example when you by a machinery for cash following transactions occur:

Debit: Machinery A/C ( Asset increasing, hence the Debit)
Credit: Cash/bank A/C (ASSET decreasing, hence the Credit)

Hope this helps!
