BANK

A banker or bank is a financial institution that acts as a payment agent for customers, and borrows and lends money. In some countries such as Germany and Japan banks are the primary owners of industrial corporations while in other countries such as the United States banks are prohibited from owning non-financial companies.
Banks act as payment agents by conducting current accounts for customers, paying cheques drawn by customers on the bank, and collecting cheques deposited to customers' current accounts. Banks also enable customer payments via other payment methods such as telegraphic transfer, EFTPOS, and ATM.
Banks borrow money by accepting funds deposited on current account, accepting term deposits and by issuing debt securities such as banknotes and bonds. Banks lend money by making advances to customers on current account, by making installment loans, and by investing in marketable debt securities and other forms of lending.
Banks provide almost all payment services, and a bank account is considered indispensable by most businesses, individuals and governments. Non-banks that provide payment services such as remittance companies are not normally considered an adequate substitute for having a bank account.
Banks borrow most funds borrowed from households and non-financial businesses, and lend most funds lent to households and non-financial businesses, but non-bank lenders provide a significant and in many cases adequate substitute for bank loans, and money market funds, cash management trusts and other non-bank financial institutions in many cases provide an adequate substitute to banks for lending savings to.

ORIGIN OF THE WORD "BANK"

The name bank derives from the Italian word banco "desk/bench", used during the Renaissance by Florentines bankers, who used to make their transactions above a desk covered by a green tablecloth.[1] However, there are traces of banking activity even in ancient times.
In fact, the word traces its origins back to the Ancient Roman Empire, where moneylenders would set up their stalls in the middle of enclosed courtyards called macella on a long bench called a bancu, from which the words banco and bank are derived. As a moneychanger, the merchant at the bancu did not so much invest money as merely convert the foreign currency into the only legal tender in Rome- that of the Imperial Mint.

ECONOMIC FUNCTIONS OF THE BANK

The economic functions of banks include:
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.
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.
credit intermediation -- banks borrow and lend back-to-back on their own account as middle men
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.
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.

LAWS OF BANKING

Banking law is based on a contractual analysis of the relationship between the bank and the customer. The definition of bank is given above, and the definition of customer is any person for whom the bank agrees to conduct an account.
The law implies rights and obligations into this relationship as follows:
The bank account balance is the financial position between the bank and the customer, when the account is in credit, the bank owes the balance to the customer, when the account is overdrawn, the customer owes the balance to the bank.
The bank engages to pay the customer's cheques up to the amount standing to the credit of the customer's account, plus any agreed overdraft limit.
The bank may not pay from the customer's account without a mandate from the customer, e.g. a cheque drawn by the customer.
The bank engages to promptly collect the cheques deposited to the customer's account as the customer's agent, and to credit the proceeds to the customer's account.
The bank has a right to combine the customer's accounts, since each account is just an aspect of the same credit relationship.
The bank has a lien on cheques deposited to the customer's account, to the extent that the customer is indebted to the bank.
The bank must not disclose the details of the transactions going through the customer's account unless the customer consents, there is a public duty to disclose, the bank's interests require it, or under compulsion of law.
The bank must not close a customer's account without reasonable notice to the customer, because cheques are outstanding in the ordinary course of business for several days.
These implied contractual terms may be modified by express agreement between the customer and the bank. The statutes and regulations in force in the jurisdiction may also modify the above terms and/or create new rights, obligations or limitations relevant to the bank-customer relationship.

BANK CRISIS

Banks are susceptible to many forms of risk which have triggered occasional systemic crises. Risks include liquidity risk (the risk that many depositors will request withdrawals beyond available funds), credit risk (the risk that those who owe money to the bank will not repay), and interest rate risk (the risk that the bank will become unprofitable if rising interest rates force it to pay relatively more on its deposits than it receives on its loans), among others.

CHALLENGES WITHIN THE BANKING INDUSTRIES

The banking industry is a highly regulated industry with detailed and focused regulators. All banks with FDIC-insured deposits have the FDIC as a regulator; however, for examinations, the Federal Reserve is the primary federal regulator for Fed-member state banks; the Office of the Comptroller of the Currency (“OCC”) is the primary federal regulator for national banks; and the Office of Thrift Supervision, or OTS, is the primary federal regulator for thrifts. State non-member banks are examined by the state agencies as well as the FDIC. National banks have one primary regulator—the OCC.
Each regulatory agency has their own set of rules and regulations to which banks and thrifts must adhere.
The Federal Financial Institutions Examination Council (FFIEC) was established in 1979 as a formal interagency body empowered to prescribe uniform principles, standards, and report forms for the federal examination of financial institutions. Although the FFIEC has resulted in a greater degree of regulatory consistency between the agencies, the rules and regulations are constantly changing.
In addition to changing regulations, changes in the industry have led to consolidations within the Federal Reserve, FDIC, OTS and OCC. Offices have been closed, supervisory regions have been merged, staff levels have been reduced and budgets have been cut. The remaining regulators face an increased burden with increased workload and more banks per regulator. While banks struggle to keep up with the changes in the regulatory environment, regulators struggle to manage their workload and effectively regulate their banks. The impact of these changes is that banks are receiving less hands-on assessment by the regulators, less time spent with each institution, and the potential for more problems slipping through the cracks, potentially resulting in an overall increase in bank failures across the United States.
