Why a bank , cash deposit say Credit, Withdraw say Debit why?

Banks consider their clients as creditor's when they deposit cash to their bank accounts while the clients consider the bank as debtor's henceforth banks treat cash deposit as a liability in the books of account and clients treat cash deposits to the bank as asset in their books of account. The nature of engagement and transaction between a bank and client's is that of receivable and payable relationship.

Customer deposit is Payable liability for bank. When customer deposit it shows the bank liability increase. 

So according to the basic rules of accounting....

Liability increase = Credit 

 

Customer withdraw decrease the bank liability....

So Liability decrease = Debit

It's simple  !!!

Entries reflecting in their Books of Accounts

 

When you deposit Cash at Bank  Accounting entry is Dr. Bank To Cash/ Customer whatever applicable

Same When you withdraw Credit BANK & Dr. to CASH A/c (or) Vendor A/c, if it's payment to vendor

For the Bank. You are a customer. the amount deposited by customer is payable by bank hence it is a credit balance for bank.

Cash deposit is credit because , your balance increase because the roles when asset increas it will be credit, and for cash withdraw it means your balanc is decrease , the roles when asset  decrease it will be debit

The cash you deposit to a bank account is a receivable asset for you and it is a liability account to the bank so when you deposit a cash in your account, the bank's payable account is increased and as you know an increase ib a liability account is credited. on the other hand, when you withdraw cash from the bank the liability of the bank is decreased and a decreas in a liability is debited. so, that is why the bank records a credit when you deposit cash and a debit when you withdraw cash from your account

Cash deposit is credit because , from the bank's point of view, cash deposit is a liability to them since it is a deposit liability and withdraw as debit because its as if they have paid their debt.

Because when customer deposit cash to bank, it will be the liability to the bank to Return the money.

increase in liability will be credit

and decrease in liability will be debit
