Types of banks and economic functions Banks' activities can be divided into retail banking, dealing directly with individuals and small businesses; business banking, providing services to mid-market business; corporate banking, directed at large business entities; private banking, providing wealth management services to High Net Worth Individuals and families; and investment banking, relating to activities on the financial markets. Most banks are profit-making, private enterprises. However, some are owned by government, or are non-profits.
Central banks are normally government owned banks, often charged with quasi-regulatory responsibilities, e.g. supervising commercial banks, or controlling the cash interest rate. They generally provide liquidity to the banking system and act as Lender of last resort in event of a crisis.
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 and effectively transferable by mere delivery in the case of banknotes, or by drawing a cheque, delivering it to the payee to bank or cash.
2. netting and settlement of payments -- banks act both as collection agent and paying agents for customers, and participate in inter-bank 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 payment flows between geographical areas to offset, reducing the cost of settling payments between geographical areas.
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 the bank's own capital which provides a buffer to absorb losses without defaulting on its own obligations. However, since banknotes and deposits are generally unsecured, if the bank gets into difficulty and pledges assets as security to try to get 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. Bank can do this because they can aggregate issues (e.g. accepting deposits and issuing banknotes) and redemptions (e.g. withdrawals and redemptions of banknotes), maintain reserves of cash, invest in marketable securities that can be readily converted to cash if needed, and raise replacement funding as needed from various sources (e.g. wholesale cash markets and securities markets) because they have a high and more well known credit quality than most other borrowers.
