Banking Services
A bank is a commercial or state institution that provides financial services , including issuing money in various forms, receiving deposits of money, lending money and processing transactions and the creating of credit. A commercial bank accepts deposits from customers and in turn makes loans, even in excess of the deposits; a process known as fractional-reserve banking. Some banks (called Banks of issue) issue banknotes as legal tender. Many banks offer ancillary financial services to make additional profit; for example, most banks also rent safe deposit boxes in their branches.

Currently in most jurisdictions commercial banks are regulated and require permission to operate. Operational authority is granted by bank regulatory authorities which provides rights to conduct the most fundamental banking services such as accepting deposits and making loans. A commercial bank is usually defined as an institution that both accepts deposits and makes loans; there are also financial institutions that provide selected banking services without meeting the legal definition of a bank.

Banks have influenced economies and politics for centuries. Historically, the primary purpose of a bank was to provide loans to trading companies. Banks provided funds to allow businesses to purchase inventory, and collected those funds back with interest when the goods were sold. For centuries, the banking industry only dealt with businesses, not consumers. Commercial lending today is a very intense activity, with banks carefully analyzing the financial condition of their business clients to determine the level of risk in each loan transaction. Banking services have expanded to include services directed at individuals, and risk in these much smaller transactions are pooled.

A bank generates a profit from the differential between the level of interest it pays for deposits and other sources of funds, and the level of interest it charges in its lending activities. This difference is referred to as the spread between the cost of funds and the loan interest rate. Historically, profitability from lending activities has been cyclic and dependent on the needs and strengths of loan customers. In recent history, investors have demanded a more stable revenue stream and banks have therefore placed more emphasis on transaction fees, primarily loan fees but also including service charges on array of deposit activities and ancillary services (international banking, foreign exchange, insurance, investments, wire transfers, etc.). However, lending activities still provide the bulk of a commercial bank's income.

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.[citation needed] However, there are traces of banking activity even in the babylonian times, and indeed a book about the history of banking is named : Banking, from Babylon to Wall Street.

Types of Banks
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; 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 non-commercial bodies or government agencies often charged with controlling interest rates and money supply across the whole economy. They generally provide liquidity to the banking system and act as Lender of last resort in event of a crisis.

Types of Retail Banks

  • Commercial Bank: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 underserved markets or populations.
  • Postal Savings Banks:Savings banks associated with national postal systems.
  • Private Banks:Manage the assets of high net worth individuals.
  • Offshore Banks:Banks located in jurisdictions with low taxation and regulation. Many offshore banks are essentially private banks.
  • Savings Bank:In Europe, savings banks take their roots in the 19th or sometimes even 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, while 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 decentralised distribution network, providing local and regional outreach and by their socially responsible approach to business and society.
  • Building Societies and Lands Banks:Conduct retail banking.
  • Ethical Banks:Banks that prioritize the transparency of all operations and make only what they consider to be socially-responsible investments.
Types of Investment Banks
  • Investment banks "underwrite" (guarantee the sale of) stock and bond issues, trade for their own accounts, make markets, and advise corporations on capital markets activities such as mergers and acquisitions.
  • Merchant banks were traditionally banks which engaged in trade financing. The modern definition, however, refers to banks which provide capital to firms in the form of shares rather than loans. Unlike Venture capital firms, they tend not to invest in new companies.
Both Combined
Universal banks, more commonly known as a financial services company, engage in several of these activities. For example, First Bank (a very large bank) is involved in commercial and retail lending, and its subsidiaries in tax-havens offer offshore banking services to customers in other countries. Other large financial institutions are similarly diversified and engage in multiple activities. In Europe and Asia, big banks are very diversified groups that, among other services, also distribute insurance, hence the term bank assurance is the term used to describe the sale of insurance products in a bank. The word is a combination of "banque or bank" and "assurance" signifying that both banking and insurance are provided by the same corporate entity.
