A bank is a financial institution and a financial intermediary that accepts deposits and channels those deposits into lending activities, either directly or through capital markets. A bank connects customers that have capital deficits to customers with capital surpluses.[citation needed]
Due to their critical status within the financial system and the economy[citation needed] generally, banks are highly regulated in most countries. Most banks operate under a system known as fractional reserve banking where they hold only a small reserve of the funds deposited and lend out the rest for profit. They are generally subject to minimum capital requirements which are based on an international set of capital standards, known as the Basel Accords.
The oldest bank still in existence is Monte dei Paschi di Siena, headquartered in Siena, Italy, which has been operating continuously since 1472. It is followed by Berenberg Bank of Hamburg (1590) and Sveriges Riksbank of Sweden (1668).
Banking in the modern sense of the word can be traced to medieval and early Renaissance Italy, to the rich cities in the north like Florence, Venice and Genoa. The Bardi and Peruzzi families dominated banking in 14th century Florence, establishing branches in many other parts of Europe. One of the most famous Italian banks was the Medici Bank, set up by Giovanni di Bicci de' Medici in 1397. The earliest known state deposit bank, Banco di San Giorgio (Bank of St. George), was founded in 1407 at Genoa, Italy.
[edit]Origin of the word
The word bank was borrowed in Middle English from Middle French banque, from Old Italian banca, from Old High German banc, bank "bench, counter". Benches were used as desks or exchange counters during the Renaissance by Florentine bankers, who used to make their transactions atop desks covered by green tablecloths.[6]
One of the oldest items found showing money-changing activity is a silver Greek drachm coin from ancient Hellenic colony Trapezus on the Black Sea, modern Trabzon, c. 350–325 BC, presented in the British Museum in London. The coin shows a banker's table (trapeza) laden with coins, a pun on the name of the city. In fact, even today in Modern Greek the word Trapeza means both a table and a bank.
Another possible origin of the word is from the Sanskrit words 'byaya' (expense) and 'onka' (calculation) = byaya-onka. This word still survives in Bangla, which is one of Sanskrit's child languages. Such expense calculations were the biggest part of mathematical treatises written by Indian mathematicians as early as 500 B.C.
