what is bank?

Bank

A bank is a financial intermediary that accepts deposits and channels those deposits into lending activities, either directly by loaning or indirectly through capital markets. A bank links customers that have capital deficits and customers with capital surpluses.
Due to their importance in the financial system and influence on national economies, banks are highly regulated in most countries. Most nations have institutionalised a system known as fractional reserve banking, under which banks hold liquid assets equal to only a portion of their current liabilities. In addition to other regulations intended to ensure liquidity, banks are generally subject to minimum capital requirements based on an international set of capital standards, known as the Basel Accords.
Banking in its modern sense evolved in the 14th century in the rich cities of Renaissance Italy but in many ways was a continuation of ideas and concepts of credit and lending that had its roots in the ancient world. In the history of banking, a number of banking dynasties—notably the Medicis, the Fuggers, the Welsers, the Berenbergs, and the Rothschilds—have played a central role over many centuries. The oldest existing retail bank is Monte dei Paschi di Siena, while the oldest existing merchant bank is Berenberg Bank.

Economic functions

The economic functions of banks include:

1. Issue of money, in the form of banknotes and current accounts subject to check or payment at the customer's order. These claims on banks can act as money because they are negotiable 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 check 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 economize 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. Asset liability mismatch/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 redemption 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).
6. Money creation – whenever a bank gives out a loan in a fractional-reserve banking system, a new sum of virtual money is created.

   Types of banks

   Banks' activities can be divided into:
   
7. retail banking, dealing directly with individuals and small businesses;
8. business banking, providing services to mid-market business;
9. corporate banking, directed at large business entities;
10. private banking, providing wealth management services to high net worth individuals and families;
11. 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-profit organizations.

• Commercial banks: the term used for a normal bank to distinguish it from an investment bank. After the Great Depression, the U.S. Congress required that banks only engage in banking activities, whereas investment banks were limited to capital market activities. Since the two no longer have to be under separate ownership, some use the term "commercial bank" to refer to a bank or a division of a bank that mostly deals with deposits and loans from corporations or large businesses.
• Community banks: locally operated financial institutions that empower employees to make local decisions to serve their customers and the partners.
• Community development banks: regulated banks that provide financial services and credit to under-served markets or populations.
• Land development banks: The special banks providing Long Term Loans are called Land Development Banks, in the short, LDB. The history of LDB is quite old. The first LDB was started at Jhang in Punjab in 1920. The main objective of the LDBs are to promote the development of land, agriculture and increase the agricultural production. The LDBs provide long-term finance to members directly through their branches.^[19]
• Credit unions or Co-operative Banks: not-for-profit cooperatives owned by the depositors and often offering rates more favorable than for-profit banks. Typically, membership is restricted to employees of a particular company, residents of a defined area, members of a certain union or religious organizations, and their immediate families.
• Postal savings banks: savings banks associated with national postal systems.
• Private banks: banks that manage the assets of high net worth individuals. Historically a minimum of USD 1 million was required to open an account, however, over the last years many private banks have lowered their entry hurdles to USD 250,000 for private investors.^{[citation needed]}
• Offshore banks: banks located in jurisdictions with low taxation and regulation. Many offshore banks are essentially private banks.
• Savings bank: in Europe, savings banks took their roots in the 19th or sometimes even in the 18th century. Their original objective was to provide easily accessible savings products to all strata of the population. In some countries, savings banks were created on public initiative; in others, socially committed individuals created foundations to put in place the necessary infrastructure. Nowadays, European savings banks have kept their focus on retail banking: payments, savings products, credits and insurances for individuals or small and medium-sized enterprises. Apart from this retail focus, they also differ from commercial banks by their broadly decentralized distribution network, providing local and regional outreach—and by their socially responsible approach to business and society.
• Building societies and Landesbanks: institutions that conduct retail banking.
• Ethical banks: banks that prioritize the transparency of all operations and make only what they consider to be socially responsible investments.
• A Direct or Internet-Only bank is a banking operation without any physical bank branches, conceived and implemented wholly with networked computers.

Types of investment banks

• Investment banks "underwrite" (guarantee the sale of) stock and bond issues, trade for their own accounts, make markets, provide investment management, and advise corporations on capital market activities such as mergers and acquisitions.
• Merchant banks were traditionally banks which engaged in trade finance. The modern definition, however, refers to banks which provide capital to firms in the form of shares rather than loans. Unlike venture caps, they tend not to invest in new companies.

Both combined

• Universal banks, more commonly known as financial services companies, engage in several of these activities. These big banks are very diversified groups that, among other services, also distribute insurance— hence the term bancassurance, a portmanteau word combining "banque or bank" and "assurance", signifying that both banking and insurance are provided by the same corporate entity.

Other types of banks

• Central banks are normally government-owned and charged with quasi-regulatory responsibilities, such as supervising commercial banks, or controlling the cash interest rate. They generally provide liquidity to the banking system and act as the lender of last resort in event of a crisis.
• Islamic banks adhere to the concepts of Islamic law. This form of banking revolves around several well-established principles based on Islamic canons. All banking activities must avoid interest, a concept that is forbidden in Islam. Instead, the bank earns profit (markup) and fees on the financing facilities that it extends to customers.
