Fractional-reserve banking is the system of banking in all countries worldwide, under which banks that take deposits from the public keep only part of their deposit liabilities in liquid assets as a reserve, typically lending the remainder to borrowers. Bank reserves are held as cash in the bank or as balances in the bank's account at the central bank. Fractional-reserve banking differs from the hypothetical alternative model, full-reserve banking, in which banks would keep all depositor funds on hand as reserves.
The country's central bank may determine a minimum amount that banks must hold in reserves, called the "reserve requirement" or "reserve ratio". Most commercial banks hold more than this minimum amount as excess reserves. Some countries, e.g. the core Anglosphere countries of the United States, the United Kingdom, Canada, Australia, and New Zealand, and the three Scandinavian countries, do not impose reserve requirements at all.
Bank deposits are usually of a relatively short-term duration, and may be "at call", while loans made by banks tend to be longer-term, resulting in a risk that customers may at any time collectively wish to withdraw cash out of their accounts in excess of the bank reserves. The reserves only provide liquidity to cover withdrawals within the normal pattern. Banks and the central bank expect that in normal circumstances only a proportion of deposits will be withdrawn at the same time, and that reserves will be sufficient to meet the demand for cash. However, banks may find themselves in a shortfall situation when depositors wish to withdraw more funds than the reserves held by the bank. In that event, the bank experiencing the liquidity shortfall may borrow short-term funds in the interbank lending market from banks with a surplus. In exceptional situations, such as during an unexpected bank run, the central bank may provide funds to cover the short-term shortfall as lender of last resort.
As banks hold in reserve less than the amount of their deposit liabilities, and because the deposit liabilities are considered money in their own right (see commercial bank money), fractional-reserve banking permits the money supply to grow beyond the amount of the underlying base money originally created by the central bank. In most countries, the central bank (or other monetary policy authority) regulates bank-credit creation, imposing reserve requirements and capital adequacy ratios. This helps ensure that banks remain solvent and have enough funds to meet demand for withdrawals, and can be used to influence the process of money creation in the banking system. However, rather than directly controlling the money supply, contemporary central banks usually pursue an interest-rate target to control bank issuance of credit and the rate of inflation.
Fractional-reserve banking predates the existence of governmental monetary authorities and originated with bankers' realization that generally not all depositors demand payment at the same time. In the past, savers looking to keep their coins and valuables in safekeeping depositories deposited gold and silver at goldsmiths, receiving in exchange a note for their deposit (see Bank of Amsterdam ). These notes gained acceptance as a medium of exchange for commercial transactions and thus became an early form of circulating paper money. [1] As the notes were used directly in trade, the goldsmiths observed that people would not usually redeem all their notes at the same time, and they saw the opportunity to invest their coin reserves in interest-bearing loans and bills. This generated income for the goldsmiths but left them with more notes on issue than reserves with which to pay them. A process was started that altered the role of the goldsmiths from passive guardians of bullion, charging fees for safe storage, to interest-paying and interest-earning banks. Thus fractional-reserve banking was born. [2]
If creditors (note holders of gold originally deposited) lost faith in the ability of a bank to pay their notes, however, many would try to redeem their notes at the same time. If, in response, a bank could not raise enough funds by calling in loans or selling bills, the bank would either go into insolvency or default on its notes. Such a situation is called a bank run and caused the demise of many early banks. [1]
These early financial crises led to the creation of central banks. The Swedish Riksbank was the world's first central bank, created in 1668. Many nations followed suit in the late 1600s to establish central banks which were given the legal power to set a reserve requirement, and to specify the form in which such assets (called the monetary base) were required to be held. [3] In order to mitigate the impact of bank failures and financial crises, central banks were also granted the authority to centralize banks' storage of precious metal reserves, thereby facilitating transfer of gold in the event of bank runs, to regulate commercial banks, and to act as lender-of-last-resort if any bank faced a bank run. The emergence of central banks reduced the risk of bank runs which is inherent in fractional-reserve banking, and it allowed the practice to continue as it does today. [4] where it is the system of banking prevailing in almost all countries worldwide. [5] [6]
During the twentieth century, the role of the central bank grew to include influencing or managing various macroeconomic policy variables, including measures of inflation, unemployment, and the international balance of payments. In the course of enacting such policy, central banks have from time to time attempted to manage interest rates, reserve requirements, and various measures of the money supply and monetary base. [7]
In most legal systems, a bank deposit is not a bailment. In other words, the funds deposited are no longer the property of the customer. The funds become the property of the bank, and the customer in turn receives an asset called a deposit account (a checking or savings account). That deposit account is a liability on the balance sheet of the bank. [2]
Each bank is legally authorized to issue credit up to a specified multiple of its reserves, so reserves available to satisfy payment of deposit liabilities are less than the total amount which the bank is obligated to pay in satisfaction of demand deposits. Largely, fractional-reserve banking functions smoothly, as relatively few depositors demand payment at any given time, and banks maintain enough of a buffer of reserves to cover depositors' cash withdrawals and other demands for funds. However, during a bank run or a generalized financial crisis, demands for withdrawal can exceed the bank's funding buffer, and the bank will be forced to raise additional reserves to avoid defaulting on its obligations. A bank can raise funds from additional borrowings (e.g., by borrowing in the interbank lending market or from the central bank), by selling assets, or by calling in short-term loans. If creditors are afraid that the bank is running out of reserves or is insolvent, they have an incentive to redeem their deposits as soon as possible before other depositors access the remaining reserves. Thus the fear of a bank run can actually precipitate the crisis. [note 1]
Many of the practices of contemporary bank regulation and central banking—including centralized clearing of payments, central bank lending to member banks, regulatory auditing, and government-administered deposit insurance—are designed to prevent the occurrence of such bank runs.
Fractional-reserve banking allows banks to provide credit, which represent immediate liquidity to borrowers. The banks also provide longer-term loans, and act as financial intermediaries for those funds. [4] [8] Less liquid forms of deposit (such as time deposits) or riskier classes of financial assets (such as equities or long-term bonds) may lock up a depositor's wealth for a period of time, making it unavailable for use on demand. This "borrowing short, lending long" or maturity transformation function of fractional-reserve banking is a role that, according to many economists, can be considered to be an important function of the commercial banking system. [9]
The process of fractional-reserve banking expands the money supply of the economy but also increases the risk that a bank cannot meet its depositor withdrawals. Modern central banking allows banks to practice fractional-reserve banking with inter-bank business transactions with a reduced risk of bankruptcy. [10] [11]
Additionally, according to macroeconomic theory, a well-regulated fractional-reserve bank system could be used by the central bank to influence the money supply and interest rates. Influencing interest rates are an important part of monetary policy used by central banks to promote macroeconomic stability. [12] Historically, central banks have occasionally changed reserve requirements discretionarily in order to influence the money supply directly and via that mechanism the interest rate level. Today, however, this implementation policy is rarely used. In the US, the Federal Reserve eliminated reserve requirements entirely in 2020, instead preferring to use changes in the interest rate paid on reserves held by commercial banks as its most important monetary policy instrument to directly influence the broader interest rate level in the economy. [13]
When a loan is made by the commercial bank, the bank creates new demand deposits and the money supply expands by the size of the loan. [4]
The proceeds of most bank loans are not in the form of currency. Banks typically make loans by accepting promissory notes in exchange for credits they make to the borrowers' deposit accounts. [14] Deposits created in this way are sometimes called derivative deposits and are part of the process of creation of money by commercial banks. [15] Issuing loan proceeds in the form of paper currency and current coins is considered to be a weakness in internal control. [16]
The money creation process is also affected by the currency drain ratio (the propensity of the public to hold banknotes rather than deposit them with a commercial bank), and the safety reserve ratio (excess reserves beyond the legal requirement that commercial banks voluntarily hold). Data for reserves and vault cash are published regularly by the Federal Reserve in the United States. [17] The Federal Reserve does not impose a reserve requirement, but pays interest on reserve balances, influencing the general interest rate level in the economy in that way. [18]
Just as taking out a new loan expands the money supply, the repayment of bank loans reduces the money supply. [19]
There are two types of money created in a fractional-reserve banking system operating with a central bank: [20] [21] [22]
The money multiplier is a heuristic traditionally used to demonstrate the maximum amount of broad money that could be created by commercial banks for a given fixed amount of base money and reserve ratio. This theoretical maximum is never reached, because some eligible reserves are held as cash outside of banks. [23] Rather than holding the quantity of base money fixed, contemporary central banks typically focus on setting and maintaining target interest rates in order to satisfy their monetary policy goals, [24] implying that the theoretical ceiling imposed by the money multiplier does not impose a limit on money creation in practice. [25]
The money multiplier, m, is the inverse of the reserve requirement, R: [26]
In countries where the central bank does not impose a reserve requirement, such as the United States, Canada and the United Kingdom, the theoretical money multiplier is undefined, having a denominator of zero. [27]
In countries with fractional-reserve banking, commercial bank money usually forms the majority of the money supply. [20] The acceptance and value of commercial bank money is based on the fact that it can be exchanged freely at a commercial bank for central bank money. [20] [21]
The actual increase in the money supply through this process may be lower, as (at each step) banks may choose to hold reserves in excess of the statutory minimum, borrowers may let some funds sit idle, and some members of the public may choose to hold cash, and there also may be delays or frictions in the lending process. [28] Government regulations may also limit the money creation process by preventing banks from giving out loans even when the reserve requirements have been fulfilled. [29]
Because the nature of fractional-reserve banking involves the possibility of bank runs, central banks have been created throughout the world to address these problems. [7] [30]
Government controls and bank regulations related to fractional-reserve banking have generally been used to impose restrictive requirements on note issue and deposit-taking on the one hand, and to provide relief from bankruptcy and creditor claims, and/or protect creditors with government funds, when banks defaulted on the other hand. Such measures have included:
The currently prevailing view of reserve requirements is that they are intended to prevent banks from:
In some jurisdictions (such as the European Union), the central bank does not require reserves to be held during the day.[ citation needed ][ clarification needed ] Reserve requirements are intended to ensure that the banks have sufficient supplies of highly liquid assets, so that the system operates in an orderly fashion and maintains public confidence.
In other jurisdictions (such as the United States, [31] Canada, [32] : 347 [33] : 5 the United Kingdom, [32] Australia, [34] New Zealand, [35] and the Scandinavian countries [36] ), the central bank does not require reserves to be held at any time – that is, it does not impose reserve requirements.
In addition to reserve requirements, there are other required financial ratios that affect the amount of loans that a bank can fund. The capital requirement ratio is perhaps the most important of these other required ratios. When there are no mandatory reserve requirements, which are considered by some economists to restrict lending, the capital requirement ratio acts to prevent an infinite amount of bank lending.[ citation needed ]
To avoid defaulting on its obligations, the bank must maintain a minimal reserve ratio that it fixes in accordance with regulations and its liabilities. In practice this means that the bank sets a reserve ratio target and responds when the actual ratio falls below the target. Such response can be, for instance:
Because different funding options have different costs and differ in reliability, banks maintain a stock of low cost and reliable sources of liquidity such as:
As with reserves, other sources of liquidity are managed with targets.
The ability of the bank to borrow money reliably and economically is crucial, which is why confidence in the bank's creditworthiness is important to its liquidity. This means that the bank needs to maintain adequate capitalisation and to effectively control its exposures to risk in order to continue its operations. If creditors doubt the bank's assets are worth more than its liabilities, all demand creditors have an incentive to demand payment immediately, causing a bank run to occur.[ citation needed ]
Contemporary bank management methods for liquidity are based on maturity analysis of all the bank's assets and liabilities (off balance sheet exposures may also be included). Assets and liabilities are put into residual contractual maturity buckets such as 'on demand', 'less than 1 month', '2–3 months' etc. These residual contractual maturities may be adjusted to account for expected counterparty behaviour such as early loan repayments due to borrowers refinancing and expected renewals of term deposits to give forecast cash flows. This analysis highlights any large future net outflows of cash and enables the bank to respond before they occur. Scenario analysis may also be conducted, depicting scenarios including stress scenarios such as a bank-specific crisis.[ citation needed ]
An example of fractional-reserve banking, and the calculation of the "reserve ratio" is shown in the balance sheet below:

In this example the cash reserves held by the bank is NZ$3,010m (NZ$201m cash + NZ$2,809m balance at Central Bank) and the demand deposits (liabilities) of the bank are NZ$25,482m, for a cash reserve ratio of 11.81%.
The key financial ratio used to analyze fractional-reserve banks is the cash reserve ratio, which is the ratio of cash reserves to demand deposits. However, other important financial ratios are also used to analyze the bank's liquidity, financial strength, profitability etc.
For example, the ANZ National Bank Limited balance sheet above gives the following financial ratios:
It is important how the term "reserves" is defined for calculating the reserve ratio, as different definitions give different results. Other important financial ratios may require analysis of disclosures in other parts of the bank's financial statements. In particular, for liquidity risk, disclosures are incorporated into a note to the financial statements that provides maturity analysis of the bank's assets and liabilities and an explanation of how the bank manages its liquidity.
In 1935, economist Irving Fisher proposed a system of full-reserve banking, where banks would not lend on demand deposits but would only lend from time deposits. [37] [38] It was proposed as a method of reversing the deflation of the Great Depression, as it would give the central bank (the Federal Reserve in the US) more direct control of the money supply. [39] [ page needed ]
Austrian School economists such as Jesús Huerta de Soto and Murray Rothbard have strongly criticized fractional-reserve banking, calling for it to be outlawed and criminalized. According to them, not only does money creation cause macroeconomic instability (based on the Austrian Business Cycle Theory), but it is a form of embezzlement or financial fraud, legalized only due to the influence of powerful rich bankers on corrupt governments around the world. [40] [41] US politician Ron Paul has also criticized fractional-reserve banking based on Austrian School arguments. [42]
Adair Turner, former chief financial regulator of the United Kingdom, stated that banks "create credit and money ex nihilo – extending a loan to the borrower and simultaneously crediting the borrower's money account". [43]
The monetary policy of the United States is the set of policies which the Federal Reserve follows to achieve its twin objectives of high employment and stable inflation.
In macroeconomics, money supply refers to the total volume of money held by the public at a particular point in time. There are several ways to define "money", but standard measures usually include currency in circulation and demand deposits. Money supply data is recorded and published, usually by the national statistical agency or the central bank of the country. Empirical money supply measures are usually named M1, M2, M3, etc., according to how wide a definition of money they embrace. The precise definitions vary from country to country, in part depending on national financial institutional traditions.
The money market is a component of the economy that provides short-term funds. The money market deals in short-term loans, generally for a period of a year or less.
The Reserve Bank of India is India's central bank and regulatory body responsible for regulation of the Indian banking system. Owned by the Ministry of Finance of the Government of India, it is responsible for the control, issue and maintaining supply of the Indian rupee. It also manages the country's main payment systems and works to promote its economic development.
Full-reserve banking is a system of banking where banks do not lend demand deposits and instead only lend from time deposits. It differs from fractional-reserve banking, in which banks may lend funds on deposit, while fully reserved banks would be required to keep the full amount of each customer's demand deposits in cash, available for immediate withdrawal.
In economics, the monetary base in a country is the total amount of money created by the central bank. This includes:
A bank run or run on the bank occurs when many clients withdraw their money from a bank, because they believe the bank may fail in the near future. In other words, it is when, in a fractional-reserve banking system, numerous customers withdraw cash from deposit accounts with a financial institution at the same time because they believe that the financial institution is, or might become, insolvent. When they transfer funds to another institution, it may be characterized as a capital flight. As a bank run progresses, it may become a self-fulfilling prophecy: as more people withdraw cash, the likelihood of default increases, triggering further withdrawals. This can destabilize the bank to the point where it runs out of cash and thus faces sudden bankruptcy. To combat a bank run, a bank may acquire more cash from other banks or from the central bank, or limit the amount of cash customers may withdraw, either by imposing a hard limit or by scheduling quick deliveries of cash, encouraging high-return term deposits to reduce on-demand withdrawals or suspending withdrawals altogether.
In macroeconomics, an open market operation (OMO) is an activity by a central bank to exchange liquidity in its currency with a bank or a group of banks. The central bank can either transact government bonds and other financial assets in the open market or enter into a repurchase agreement or secured lending transaction with a commercial bank. The latter option, often preferred by central banks, involves them making fixed period deposits at commercial banks with the security of eligible assets as collateral.
Reserve requirements are central bank regulations that set the minimum amount that a commercial bank must hold in liquid assets. This minimum amount, commonly referred to as the commercial bank's reserve, is generally determined by the central bank on the basis of a specified proportion of deposit liabilities of the bank. This rate is commonly referred to as the cash reserve ratio or shortened as reserve ratio. Though the definitions vary, the commercial bank's reserves normally consist of cash held by the bank and stored physically in the bank vault, plus the amount of the bank's balance in that bank's account with the central bank. A bank is at liberty to hold in reserve sums above this minimum requirement, commonly referred to as excess reserves.
Bank reserves are a commercial bank's cash holdings physically held by the bank, and deposits held in the bank's account with the central bank. Under the fractional-reserve banking system used in most countries, central banks may set minimum reserve requirements that mandate commercial banks under their purview to hold cash or deposits at the central bank equivalent to at least a prescribed percentage of their liabilities, such as customer deposits. Such sums are usually termed required reserves, and any funds above the required amount are called excess reserves. These reserves are prescribed to ensure that, in the normal events, there is sufficient liquidity in the banking system to provide funds to bank customers wishing to withdraw cash. Even when there are no reserve requirements, banks often as a matter of prudent management hold reserves in case of unexpected events, such as unusually large net withdrawals by customers or bank runs. Traditionally, central banks do not pay interest on reserve balances, but such schemes have become increasingly common in the 21st century. Funds in banks that are not retained as a reserve are available to be lent, at interest.
In monetary economics, the money multiplier is the ratio of the money supply to the monetary base. If the money multiplier is stable, it implies that the central bank can control the money supply by determining the monetary base.
Money creation, or money issuance, is the process by which the money supply of a country, or an economic or monetary region, is increased. In most modern economies, money is created by both central banks and commercial banks. Money issued by central banks is a liability, typically called reserve deposits, and is only available for use by central bank account holders, which are generally large commercial banks and foreign central banks. Central banks can increase the quantity of reserve deposits directly, by making loans to account holders, purchasing assets from account holders, or by recording an asset, such as a deferred asset, and directly increasing liabilities. However, the majority of the money supply used by the public for conducting transactions is created by the commercial banking system in the form of commercial bank deposits. Bank loans issued by commercial banks expand the quantity of bank deposits.
Money is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular country or socio-economic context. The primary functions which distinguish money are: medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment.
In financial economics, a liquidity crisis is an acute shortage of liquidity. Liquidity may refer to market liquidity, funding liquidity, or accounting liquidity. Additionally, some economists define a market to be liquid if it can absorb "liquidity trades" without large changes in price. This shortage of liquidity could reflect a fall in asset prices below their long run fundamental price, deterioration in external financing conditions, reduction in the number of market participants, or simply difficulty in trading assets.
Pushing on a string is a figure of speech for influence that is more effective in moving things in one direction than another – you can pull, but not push.
The Diamond–Dybvig model is an influential model of bank runs and related financial crises. The model shows how banks' mix of illiquid assets and liquid liabilities may give rise to self-fulfilling panics among depositors. Diamond and Dybvig, along with Ben Bernanke, were the recipients of the 2022 Nobel Prize in Economics for their work on the Diamond-Dybvig model.
A bank is a financial institution that accepts deposits from the public and creates a demand deposit while simultaneously making loans. Lending activities can be directly performed by the bank or indirectly through capital markets.
The interbank lending market is a market in which banks lend funds to one another for a specified term. Most interbank loans are for maturities of one week or less, the majority being overnight. Such loans are made at the interbank rate. A sharp decline in transaction volume in this market was a major contributing factor to the collapse of several financial institutions during the financial crisis of 2007–2008.
A deposit account is a bank account maintained by a financial institution in which a customer can deposit and withdraw money. Deposit accounts can be savings accounts, current accounts or any of several other types of accounts explained below.
Liquidity regulations are financial regulations designed to ensure that financial institutions have the necessary assets on hand in order to prevent liquidity disruptions due to changing market conditions. This is often related to reserve requirement and capital requirement but focuses on the specific liquidity risk of assets that are held.
