Accounting for bank accounts

Accounting for bank accounts

Bank statements are accounting records produced by banks under the various accounting standards of the world. Under GAAP and IFRS there are two kinds of accounts: debit and credit. Credit accounts are Revenue, Equity and Liabilities. Debit Accounts are Assets and Expenses. This means you credit a credit account to increase its balance, and you debit a debit account to increase its balance.^[7]

This also means you debit your savings account every time you deposit money into it (and the account is normally in deficit), while you credit your credit card account every time you spend money from it (and the account is normally in credit).

However, if you read your bank statement, it will say the opposite—that you credit your account when you deposit money, and you debit it when you withdraw funds. If you have cash in your account, you have a positive (or credit) balance; if you are overdrawn, you have a negative (or deficit) balance.

The reason for this is that the bank, and not you, has produced the bank statement. Your savings might be your assets, but the bank's liability, so they are credit accounts (which should have a positive balance). Conversely, your loans are your liabilities but the bank's assets, so they are debit accounts (which should have a also have a positive balance).

Where bank transactions, balances, credits and debits are discussed below, they are done so from the viewpoint of the account holder—which is traditionally what most people are used to seeing.

Wider commercial role

The commercial role of banks is not limited to banking, and includes:

• issue of banknotes (promissory notes issued by a banker and payable to bearer on demand)
• processing of payments by way of telegraphic transfer, EFTPOS, internet banking or other means
• issuing bank drafts and bank cheques
• accepting money on term deposit
• lending money by way of overdraft, installment loan or otherwise
• providing documentary and standby letters of credit (trade finance), guarantees, performance bonds, securities underwriting commitments and other forms of off-balance sheet exposures
• safekeeping of documents and other items in safe deposit boxes
• currency exchange
• acting as a 'financial supermarket' for the sale, distribution or brokerage, with or without advice, of insurance, unit trusts and similar financial products

Economic functions

The economic functions of banks include:

1. issue of money, in the form of banknotes and current accounts subject to cheque or payment at the customer's order. These claims on banks can act as money because they are negotiable and/or repayable on demand, and hence valued at par. They are effectively transferable by mere delivery, in the case of banknotes, or by drawing a cheque that the payee may bank or cash.
2. netting and settlement of payments – banks act as both collection and paying agents for customers, participating in interbank clearing and settlement systems to collect, present, be presented with, and pay payment instruments. This enables banks to economise on reserves held for settlement of payments, since inward and outward payments offset each other. It also enables the offsetting of payment flows between geographical areas, reducing the cost of settlement between them.
3. credit intermediation – banks borrow and lend back-to-back on their own account as middle men
4. credit quality improvement – banks lend money to ordinary commercial and personal borrowers (ordinary credit quality), but are high quality borrowers. The improvement comes from diversification of the bank's assets and capital which provides a buffer to absorb losses without defaulting on its obligations. However, banknotes and deposits are generally unsecured; if the bank gets into difficulty and pledges assets as security, to raise the funding it needs to continue to operate, this puts the note holders and depositors in an economically subordinated position.
5. maturity transformation – banks borrow more on demand debt and short term debt, but provide more long term loans. In other words, they borrow short and lend long. With a stronger credit quality than most other borrowers, banks can do this by aggregating issues (e.g. accepting deposits and issuing banknotes) and redemptions (e.g. withdrawals and redemptions of banknotes), maintaining reserves of cash, investing in marketable securities that can be readily converted to cash if needed, and raising replacement funding as needed from various sources (e.g. wholesale cash markets and securities markets).
