Bank

The essential function of a bank is to provide services related to the storing of deposits and the extending of credit. The evolution of banking dates back to the earliest writing, and continues in the present where a bank is a financial institution that provides banking and other financial services. Currently the term bank is generally understood as an institution that holds a banking license. Banking licenses are granted by bank regulatory authorities and provide rights to conduct the most fundamental banking services such as accepting deposits and making loans. There are also financial institutions that provide certain banking services without meeting the legal definition of a bank, a so called non-bank. Banks are a subset of the financial services industry.

Role in the money supply

A bank raises funds by attracting deposits, borrowing money in the inter-bank market, or issuing financial instruments in the money market or a capital market. The bank then lends out most of these funds to borrowers.

However, it would not be prudent for a bank to lend out all of its balance sheet. It must keep a certain proportion of its funds in reserve so that it can repay depositors who withdraw their deposits. Bank reserves are typically kept in the form of a deposit with a central bank. This behaviour is called fractional-reserve banking and it is a central issue of monetary policy. Some governments (or their central banks) restrict the proportion of a bank's balance sheet that can be lent out, and use this as a tool for controlling the money supply. Even where the reserve ratio is not controlled by the government, a minimum figure will still be set by regulatory authorities as part of bank regulation.
