is nonetheless a serious defect of our present fractional reserve system that it
requires continuous jiggling of monetary tools...
...recommending that the present system be replaced by one in which 100% reserves are required.
I urge that interest be paid on the 100% reserves.
Milton Friedman, 1976 Nobel Prize laureate (from his 1959 book, Ch. 3)
truly urgent problem, I think, is the abuse of deposit insurance.
"One-stop" banking and financial servicing is a popular slogan, but it tends to fall apart under close scrutiny.
Collecting various services under one roof will not make your visit "one-stop" except for parking your car.
"One-statement" finance is probably another mirage.
Companies owning banks must be prevented from placing the risks of their various activities on those safety nets.
James Tobin, 1981 Nobel Prize laureate (from a 1987 article)
What is "narrow banking?"
The narrow banking proposal calls for a total separation of bank deposit accounts from banks' lending activities to address the following issues:
The term "narrow banking" was coined in Litan (1987).
What are the main objectives of narrow banking?
But, why should I care? My bank is FDIC insured!
Not so fast, as it turns out, your "insurance" company does not have a lot of money. The Federal Deposit Insurance Corporation (FDIC) reports that its deposit insurance fund has $72.6 billion, which constitutes a reserve ratio of 1.11% out of total deposits. This means that the FDIC fund can recover less than 2% of total deposits during bank failures. To obtain a rough estimate for why the FDIC becomes almost irrelevant during financial crises, each of the three-largest U.S. banks ranked by total deposits holds over $1.2 trillion ($1,200 billions) worth of deposits. More precisely, the amount of deposits held by each of the 24 largest banks in the U.S. is larger than the entire FDIC fund.
Another common misperception related to the "safety" of bank deposits stems from the fact that depositors are not aware that they are not first priority in bank liquidations regardless of how much money they deposited. Bankruptcy liquidation priorities are discussed in Marino and Bennett (1999).
But, central banks argue that banks are "safe" now
What central banks attempt to do is to raise banks' capital requirement to 18%. What's odd about this is that central banks and even academia ignore the simple fact that major banks that failed in the 1930s held over 20% equity on their balance sheets, see Foroohar (2016, p.33). The evidence provided below shows that banks fail because they take risks with depositors' and other lenders' money and these risks and the resulting losses have little to do with equity shortage.
Although some forms of fractional-reserve banking prevailed even before the Middle Ages, reliable records of bank failures are available since 13th-century Europe.
In 1345, Florence's world biggest international bank (owned by the Bardi and Peruzzi companies) failed after 30 years of extensive credit extension and fictitious financial practices, resulting in a global financial collapse.
n 1584, Venice's largest bank House of Pisano & Tiepolo closed because of inability to refund depositors. The bank was made into a state banks, and then failed in 1619. By that time, 96 banks have already failed in Venice, Roberds and Velde (2014, p.19).
In 1791, the Bank of Amsterdam was taken over by the city. Established in 1609, the original charter required the bank to make deposits redeemable on demand as a "narrow" bank, but the bank quickly began lending, Roberds and Velde (2014, p.35), Quinn and Roberds (2014, p.10). As Fisher (1936) points out, the Bank of Amsterdam in the 17th Century "...broke faith and secretly lent out some of its 100% reserves. Ultimately, this policy caused its failure..."
In 1992, Scandinavian banks fail. The government of Sweden guaranteed all bank deposits of the nation's 114 banks and assumed some of bad debts.

British bank failures and government bailouts: 1825, 1836, 1847, 1914, and 2007-2009.
Major U.S. banking crises: 1792, 1837, 1839, 1857, 1863, 1873, 1884, 1890, 1893, 1896, 1907, 1920s, 1930-1933, 1980s, and 2007-2009.
The chart below illustrates the number of U.S. banks that failed since 1865.
As the figure shows, bank crises follow a cycle of 10 to 20 years, with the exception of the period between the 1940 to the mid-1980s (S&L crisis).

2016-2017: In December 2016, the government of Italy approved a taxpayer bailout of Italy's largest and oldest bank Monte dei Paschi di Siena. This would be the third time the bank is rescued using taxpayers' money. Paradoxically, Monte dei Paschi purchased consulting services from JPMorgan Chase that in 2008 was also rescued with billions of dollars of taxpayer money.
The big puzzle
Then, how can it happen that...
This complicated question has a simple answer: Banks rely on taxpayer implicit and explicit unconditional guarantees to bail them out.
Banks all over the world operate under the self-fulfilling expectation that governments do not have the political strength to leave depositors without money after their bank fails to return their money. In addition, banks rely on low-cost services provided by central banks only to banks.
What kinds of subsidy?
Explicit and implicit public subsides provided exclusively to banks include:
Economic consequences of the subsidies
Noss and Sowerbutts (2012) explain why the implicit subsidy arises and why it remains a public policy concern. Taxpayer-provided subsidies of banks generate three types of distortion:
Empirical estimations of the subsidies
Implicit subsidies of banks are hard to quantify because they are not recorded or published by governments. In fact, most taxpayers are not even aware of the subsidies they provide to banks. Therefore, the measurements of bank activities must first be extracted from hard data and only then be put into models that yield estimates of the monetary value of these subsidies.
Noss and Sowerbutts (2012) describe the different approaches used in the literature in order to estimate implicit subsidies. The two main approaches are:
Focusing only on the banks' cost of funding advantage aspect of the government subsidy, Acharya et al. (2015) show that the dollar value of the annual implicit subsidy accruing to major U.S. financial institutions amounts to on average $30 billion per year and rose above $70 billion during the recent financial crisis.
Moreover, Marques et al. (2013) provide international evidence on government support and risk-taking in the banking sector. They show that the provision of explicit and implicit government guarantees affects the willingness of banks to take risk by reducing market discipline. More precisely, they find that more government support is associated with more risk-taking by banks, especially during the recent financial crisis (2009-2010).
Taxpayer and central bank direct subsidies during banking crises
So far, we have described how governments (taxpayers) subsidize banks on a daily basis by providing explicit and implicit guarantees to bail out failing banks. However, taxpayers bear additional costs during financial crises when governments actually transfer money to banks so that banks could meet their obligations to creditors and depositors.
So how much it costs taxpayers to bail out failing banks? According to Curry and Shibut (2000), during the savings and loan crisis (S&L), 296 financial institutions with total assets of $125 billion were either closed or rescued from 1986 to 1989. In 1989, 747 additional thrifts with $394 billion were resolved. The S&L crisis had cost taxpayers $124 billion and the thrift industry another $29 billion.
In 1992, the Swedish government guaranteed all bank deposits of the nation's 114 banks and assumed some of their bad debts. In March 2013 the ECB and the IMF arranged for a €10 billion bailout of Cyprus' banks.
The direct taxpayer cost of the most recent 2008 crisis exceeded $700 billion. In addition, the cumulative bailout commitment (asset purchases plus lending by the Federal Reserve) during 2007-2009 was $7.77 trillion (Bloomberg) and over $29 trillion according to Felkerson (2011). Initially, the Fed tried to conceal this information from the public, but later was forced to release it after Bloomberg sued.
Oxera (2011), provides an estimation of the average taxpayer subsidy of U.K. banks in the years following the recent banking crisis. The average state support in 2009 for the top 5 U.K. banks exceeded £100 billion, with the average per bank being around £26 billion. This is in addition to the £56 the banks received in 2008.
In December 2016, the government of Italy approved a €20 billion taxpayer finance of Italy's largest and oldest bank, Monte dei Paschi di Siena. This is in addition to the €3.9 billion received in 2013. Italy's taxpayers are already exposed to debt levels of 133% of GDP even before this bailout (second-highest in Europe).
Social costs of banking crises
The implicit and explicit subsidies of banks constitute a small fraction of the social cost of a financial crisis. n a cross-country analysis, Hoggarth et al. (2002) estimate the cost of banking crisis to be between 15% to 20% of an annual GDP. Atkinson et al. (2013) estimate the social cost of the 2007–2009 financial crisis to be between 40% to 90% of one year's output ($6 trillion to $14 trillion, which translates to $50,000 to $120,000 for every U.S. household).
Epstein and Montecino (2016) estimate social costs by analyzing three components: (a) rents, or excess profits; (b) misallocation costs, or the price of diverting resources away from non-financial activities; and (c) crisis costs, meaning the cost of the 2008 financial crisis. Adding these together, they estimate that the financial system will impose an excess cost of as much as $22.7 trillion between 1990 and 2023, making finance in its current form a net drag on the American economy.
No, we don't. We need much less regulations!
As also argued in Kay (2010), bank regulations consistently failed to protect taxpayers from having to bail failed banks. And this is for the following three reasons:
Even if Congress manages to pass laws that limit banks' risk-taking activities, as we show here, often, the key components of these laws are later repealed by Congress itself after banks intensify their lobbying activities.
2. Regulatory capture: Regulatory agencies have no incentives to enforce the regulations. In fact, Griffin (2010) examines the history of the Fed and its role as a protector of the interests of large banks. Jacobs and King (2016) argue that the Federal Reserve managed to overstep the U.S. constitution by giving trillions of dollars in loans to financial institutions. Their book argues that the 1913 Act managed to make the Fed totally independent political pressure. However, instead it made the Fed totally dependent on the financial sector that it is supposed to regulate. The drawback of this dependence is not only favoritism to financial institutions and revolving doors, but the total immunity from the check-and-balances democratic system and transparency. More recently, Haedtler et al. (2016) argue that the Fed should become fully public in order to represent the diversity of public interests.
3. Regulatory cost: Kupiec (2014) reports that the average employee compensation at the federal bank regulatory agencies is more than 2.7 times that of private-sector bank employees. Taxpayers eventually pay the bills. Regulation is expensive!
The failure of Basel I, II, & III ( Basel Committee on Banking Supervision)
This widely publicized international committee suggests regulatory guidelines on the minimum amount of capital banks should hold. Currently, the committee recommends a minimum Tier 1 capital ratio of 6%. To get an idea why 6% does not protect banks against failures, compare 6% with Admati and Hellwig (2014) who argue that banks should be at least 30% equity financed.
The Glass-Steagall Act of 1932–1935
Following the vast collapse of banks in 1929, this Act gave each bank one year to decide whether it would be a commercial bank or an investment bank. Commercial banks would then be prevented from dealing with non-governmental securities for their customers and for themselves. The intent behind this separation was to restrict banks from speculating with depositors' money.
Over the years, the effectiveness of this law has diminished by actual repeals of several sections of the law, by court cases, and by regulatory agencies that issues weaker interpretations of the requirements intended to separate investment banking from deposit-taking banks. For example, already in the 1960s, First National City (Citibank today) has managed to bypass this law by introducing "negotiable CDs" that were traded on a secondary market which blurred the difference between deposit-taking and investment banking, see Foroohar (2016, p.46).
Finally, in 1999, the Gramm-Leach-Biley Act removed the remaining obstacles by allowing bank subsidiaries and bank holding companies to deal with securities. Only nine years later, in 2008, large banks sought government assistance to relieve them from a variety of "bad" securities including credit default swaps, subprime lending, and collateralized debit obligations that lost their value in a short period of time.
The failure of the Dodd-Frank Act
Also known as "The Wall Street Reform and Consumer Protection Act," it was signed into law on July 21, 2010, and represents the latest failed attempt to regulate banks in order to reduce their dependence on taxpayer money after the 2008 financial crisis.
Less than 5 years after the law was signed by President Obama, intensive lobbying activities of the banks led Congress to pass a Spending Bill that rolls back a rule that restricts trade in derivatives, the financial product that helped to cause the financial crisis of 2008. This bill also removed the restrictions on the use of government money to bail out failing banks.
But, I have read in the newspaper that central banks are taking some actions now
Here is the story: On November 9, 2015, the Financial Stability Board (FSB) issued new guidelines on bank balance-sheets that require banks to increase their capital ratio to 16% by 2019 and to 18% by 2022. What's odd about these requirements is that they totally ignore the fact that major banks that failed in 1929 held over 20% equity on their balance sheets, see Foroohar (2016, p.33). Banks do not fail because of lack of capital but because they take risks with depositors' money and the type of securities they sell.
Capital ratio consists of mostly equity (value to shareholders) plus cash reserves all divided by the assets of the bank. But now, instead of calling it just capital, the regulators apply some marketing techniques and call it "Total Loss Absorbing Capacity" (TLAC), perhaps to create an impression that the taxpayer will be off the hook in future crises.
So, should we expect banks to stop failing after 2019? Wishful thinking! Even if banks will eventually comply with the TLAC requirement, the next collapse of the banking sector will require the taxpayer to be responsible for the remaining 82% of the losses (less cash reserves that banks may hold). But, these loses could be much higher because of fire sales that will diminish the value of banks' capital during the next crisis.
More regulations versus structural change
So, if banks cannot be regulated, what else can be done? The narrow banking proposal calls for a structural change of the banking industry. Financial institutions would be split into two types:
1. "Narrow" banks where depositors are backed by 100% reserves held at central banks. Part of the interest paid by the central banks could be passed on to depositors who can use these accounts as a savings option.
2. Risky banks and mutual funds that may fail from time to time, where depositors (not taxpayers) would bear all the risk. Mutual funds have the advantage that they are more transparent than banks, but this may change over time as a result of competition.
The proposal for depository institutions that maintain 100% reserves goes back to the Great Depression and is attributed to a group economists at the University of Chicago in response to the Great Depression. In 1933 the group wrote a memo (signed by Frank Knight) to Henry Wallace who then sent a letter to President Roosevelt. The memo describes the plan for how to guarantee bank deposits by requiring banks to maintain 100% reserves as well as the separation of the "Deposit and Lending functions of existing commercial banks." [p.3].
In 1939, a group of academic economists circulated "A Program for Monetary Reform" that also emphasized the need for 100% reserves. This policy plan was also supported by other well-known monetary economists such as Irving Fisher (who corresponded frequently with Roosevelt), Milton Friedman, and James Tobin, see Phillips (1992) and Benes and Kumhof (2012) for references and a more detailed description of the plan’s history.
According to Hart (1935), the proposal called for "the radical reform of the American banking system by requiring reserves of 100 percent against all deposits..." and had some support in the political world.
Friedman (1959, Ch. 3) adopted the Chicago plan and went even further by suggesting that interest be paid on the 100% reserves (by the Fed, or from a special budget allocated by the Treasury). According to Friedman, if the banking industry is competitive, this interest would also benefit depositors as some of the interest would pass-through on to depositors and therefore encourage savings. It would also compensate banks for their loss of revenue from reducing or terminating their lending activities.
In June 1934, bills were introduced in both houses of Congress requiring the "maintenance of 100 percent reserve against chequing deposits." In other words, the plans calls for a total separation of the credit functions of banks from deposit-taking related services, so that all deposits would be 100% backed by government-issued money.
Fisher’s classic endorsement of the plan:
Common critique of narrow banking
Critics of the narrow
banking proposal correctly point out that narrow banking will not fix the
financial sector because loans will be pushed into
shadow banking which is harder to regulate.
A second common critique of narrow banking is that the abolition of fractional-reserve banking will increase lending rates. Fractional-reserve banks are able to charge low rates because of the implicit and explicit taxpayer subsidy of banks. In fact, borrowing from banks is almost equivalent to borrowing from the government because governments don't let banks fail. That is, the lending market is already destroyed by not creating true competition among lenders that would not favor banks. Mutual funds and peer-to-peer lending would generate market-determined optimal lending rates, which could be higher than the ongoing rates.
Both critiques may be dismissed if all lending is shifted to mutual funds. Mutual funds in general and index funds in particular, allow investors (savers) to diversity their risk with a mixed transparent portfolios. For example, a mutual or a pension fund that invests 40% in treasury bonds, 25% in stocks, 25% in corporate bonds, and 10% in mortgages impose very small risks on savers and is unlikely to be bailed out using taxpayer money.
Definition of "fractional reserve"
Commercial banks operating today are often referred to as "fractional-reserve" depository institutions. The reason behind this terminology is that banks actually keep only a small fraction of depositors' money in the form of cash or in deposits held safely in the central bank. Therefore, most commercial banks will not able to meet the demand for cash withdrawals unless the withdrawals are made by a small fraction of account holders.
Moreover, fractional-reserve banks "bundle" risk with deposits by taking risks with depositors' money without obtaining any permission from depositors, Shy and Stenbacka (2000, 2008). This is not the case when people deposit money with mutual funds where they can choose the exact risk portfolio that meets their preference.
From Middle Ages Europe and the Renaissance to the United States
Fractional-reserve banking emerged in Europe during the Middle Ages from money changers. Whereas the use of coins by money changers has been a great improvement over barter trade by reducing the problem of double coincidence of wants, it was hard to maintain uniform quality of coins to represent a given unit of account.
Consequently, Middle Ages money changers quickly realized that they can open accounts and settle local transactions without the need of always giving and receiving metal coins. Because coins were needed only when depositors withdrew them, money changers began allowing some customers to overdraft their accounts. By doing so, money changers turned into fractional-reserve banks that we observe until this very day.
From the Middle Ages to this very day, depository institutions continued the practice of lending out depositors' money, thereby creating new money via the money multiplier.
The failure of reserve requirements
According to Feinman (1993), recognizing banks’ strong incentives to lend, some states in the United States began requiring banks to maintain some reserves on deposits.
Reserve requirements were first established at the national level in 1863 with the passage of the National Bank Act, where banks had to hold a 25% reserve against both notes and deposits—a much higher requirement than that faced by most state banks. Reserve requirements were seen as necessary for ensuring the liquidity of national bank notes and thereby reinforcing their acceptability as a medium of exchange throughout the country. In 1864, the required ratio was lowered to 15%.
The Federal Reserve Act of 1913 created a system of Reserve Banks that could act as lenders of last resort by accommodating the temporary liquidity needs. Feinman (1993) describes the reserve requirements in that era.
As of January 2015, the ongoing required reserve ratios (determined by the Board of Governors of the Federal Reserve) are: 10% for depository institutions with net transaction accounts exceeding $103.6 million, 3% for depository institutions between $14.5 and $103.6, and none for depository institutions with less than that.
During financial crises, banks often argue that they fail because the economy failed. In 2008 the economy did not fail. It is the financial sector that always fail first.
Has anything changed since the Middle Ages?
Not really, since the Middle Ages banks continue to lend money they mostly don't have. Technology may have changed, but the incentive to maximize the amount of lending has not vanished, and actually became stronger with the introduction of new financial instruments, such as subprime mortgages.
But, wait a minute, one thing did change over the years. We now have venture capital and a huge market for mutual funds. that did not exist in the Middle Ages. The mutual funds market in the U.S. has 8,000 funds (and growing) with total assets exceeding $15 trillion. Worldwide mutual fund assets now exceed $31 trillion.
The large variety of funds reflect different degrees of risk, diversification, and liquidity that savers can choose from. A large portion of these funds lend money just as banks, with the difference that mutual funds lend money they have whereas banks lend money they mostly don't have.
Perhaps the most important feature of mutual funds is that they are transparent. Each mutual fund lists its entire portfolio on the Internet so savers can switch funds whenever they want to. In contrast, banks do not tell depositors where their money goes, so depositors do not have any control over their risk.
The lack of transparency of how banks handle their depositors' money and the money they create with it reduces governments' political strength needed for refusing to bail out failing banks, because politicians will argue that depositors cannot be "punished" for risks they did not take.
Summary: Reasons for failure and non-optimality of the system
banking system has fails for the following reasons:
First known implementation of narrow banking
Bills submitted to Congress but failed to pass
In June 1934, with the knowledge of President Roosevelt, bills were introduced in both houses of Congress requiring the "maintenance of 100 percent reserve against chequing deposits." Senator Bronson Cutting introduced it in the Senate on June 6th, 1934 (S. 3744). Congressman Wright Patman introduced it in the House (H.R. 9855). Eventually, under pressure from banks, these two bills failed to pass.
Johnsen (2014) describes the collapse of Iceland's three largest banks in 2008 that caused the worst loss relative to GDP than in any other country. It is therefore less surprising the Iceland's prime minister found the political strength to commission a report on the possibility of moving Iceland to a narrow banking system, Sigurjónsson (2015).
The report finds that to accommodate their lending activities, banks expanded the money supply nineteen fold between 1994 and 2008. The report argues that banks' lending activities tend to amplify the economic cycle (expansion during boom time and contraction during downturns). In addition, the government guarantee of bank deposits gives banks an unfair competitive advantage over other non-guaranteed financial institutions.
In the same vein, McLeay et al. (2014) dismiss the textbook explanation of banks as intermediaries between lenders and borrowers. Using banks' balance sheets, they prove that new loans should counted as new money rather than as a transfer from savers to borrowers.
Huber and Robertson (2000) and Dyson et al. (2014) propose taking away banks' ability to create money and let central banks gain full control over the money supply. This will enhance stability reduce economic fluctuations. Another advantage would be that governments (not banks) will be able to collect the seigniorage revenue associated with money creation.
The most recent attempt to eliminate fractional-reserve banking is currently taking place in the ``land of banking:" Switzerland. In 2016 the Swiss government will hold a referendum on the Vollgeld Initiative that would require private banks to hold 100% reserves against their deposits.
The transition period
A complete switch to narrow banking would eliminate "money creation" by banks as banks will maintain 100% reserves mostly held in the central bank. This raises the question how money that has already been created by banks would be eliminated during the transition period.
Amazingly, the originators of the narrow banking proposal were aware of this potential problem. Fisher (1936) explicitly addressed this issue by proposing money created by banks would be turned into government loans to banks, until banks manage to collect all the money they loaned out.
A less ambitious transition period could start by providing incentives and benefits to new financial institutions that maintain 100% (such as payments service providers discussed below). The coexistence of 100% liquid banks with the traditional fractional-reserve banks would be possible if central banks pay sufficiently high interest on reserves (some of which could be passed on to depositors), see Tobin (1985).
The digital revolution
Financial technology (FinTech) is an emerging industry with startup companies that develop software for the purpose of disrupting the traditional banking sector. The book by McMillan (2014) predicts that the digital revolution will bring the banking era to an end.
The Bank for International Settlements analyzes the presence of non-banks in all stages of the payment process and across different payment instruments. These services are widely used by all sorts of consumers, including those who do not have bank accounts. For example, owners of general-purpose reloadable (GPR) prepaid cards who do not have checking accounts comprise 4.8% of U.S. adults.
Is there any hope for a change?
Just like the failed attempts during 1930s, it seems unlikely that narrow banking will be implemented in the near future because of strong resistance from the financial sector, sharp disagreements among academic economists as to whether narrow banking is the cure, and lack of motivation from the regulator side.
Is this the end? Not yet! Ongoing and emerging technologies (FinTech) are on the narrow banking side of this debate.
Some non-banks service providers are potentially "narrow" banks
Non-bank service providers such as PayPal, Venmo, Square Cash, Stripe, Dwolla, Walmart's Bluebird Card, Green Dot, Target's REDcard, and even Bitcoin, provide bank-like services at a lower cost consumers generally pay for similar bank-provided services. In fact, the linkage between technology change and narrow banking was already identified long before the term 'FinTech' existed, see Miller (1998).
Currently, non-banks that provide bank-like services are at a competitive disadvantage because they:
Policy options to promote efficiency
To overcome this obstacle and to encourage competition with established banks, it has been proposed that non-bank payment service providers would be allowed access to the same services that banks currently receive from central banks, see for example Bank of England (2015, pp.7–8). The United States OCC is now considering granting "Fintech charter" applications to become special purpose national banks.
Allowing non-banks to open accounts with central banks would remove a major obstacle faced by non-banks. Because the transactions performed via these service providers are prefunded, they actually behave as narrow banks that maintain 100% reserves and pose no risk on the system.
The advantages of moving to such an industry structure include:
But, what about the lending side?
A common criticism of the narrow banking proposal is that it neglects to reform the lending side of banks. The critics argue that narrow banking will push more lending activities into shadow banks that are also risky and less regulated.
However, this criticism neglects to consider the fact that lending could be easily managed by mutual funds. As mentioned above, the mutual funds market in the U.S. has over 8,000 funds with total assets exceeding $15 trillion. Worldwide mutual fund assets now exceed $31 trillion. Funds such as those that diversity between stocks and bonds could add 10%–30% mortgages and other household loans into their portfolios. Investors and pension funds will be able choose the funds that match their risk versus return goals.
The advantages of shifting lending activities from fractional-reserve banks to mutual funds include:
Finally, note that FinTech is already active in the lending dimension as well. Companies such as LendingClub (now public), Prosper, Lend Academy, and CommonBond, facilitate peer-to-peer lending without having to create any new money.
(1) Expansion of the banking sector crowds-out real investment
are throwing more and more of our resources, including the cream of our
youth, into financial activities remote from the production of goods and
services, into activities that generate high private rewards
disproportionate to their social productivity."
Perhaps the real danger of the fractional-reserve system is that it can grow with no bounds. The table below (King, p.95) exhibits the alarming growth in the ratio of bank assets to annual GDP.
By 2007, this ratio has reached 800% in Iceland. What fractional-reserve banks do is to increase their asset side with all kinds of financial instruments (CDO, MBS, CDS) that have nothing to do with deposit taking. Moreover, bank holding companies are not prohibited until this very day from trading and owning commodious such as aluminum and crude oil, see Omarova (2013). Once these assets lose their value, it is hard to figure out what banks did with depositors' money, and governments use taxpayer money to recover the lost funds. With narrow banks, the size of the assets equals exactly the amount deposits held by banks.
As noted in Kay (2015), since the 1960s, a larger fraction of college graduates in general, and engineering schools in particular, accepts jobs outside their field to become investment bankers or management consultants. Shy and Stenbacka (2016b) construct an overlapping-generations model to analyze the hypothesis that large banking sectors divert resources from productive activities.
Apart from the crowding-out of human capital (misallocation of skilled labor), Cecchetti and Kharroubi (2012, 2015) show theoretically as well as empirically that financial sector growth disproportionally benefits sectors with low productivity and high collaterals, thereby reducing total factor productivity growth in the economy as shown in the following graph:
The graph shows that per-worker GDP growth can decline with an increase in a country's share of employment in the financial sector (deviation above the country's mean). Similar U-shaped results are also estimated in Arcand, Berkes, and Panizza (2015), where the financial sector has negative effects on growth when the credit to the private sector reaches 80-100% of GDP. Epstein and Montecino (2016) measure the excess social cost of large financial sectors by adding three components: (a) rents, or excess profits; (b) misallocation costs, or the price of diverting resources away from real investments; and (c) crisis costs, meaning the cost of the 2008 financial crisis. They estimate that the financial system will impose an excess cost of as much as $22.7 trillion between 1990 and 2023, making finance in its current form a net drag on the American economy.
(2) A logical problem with the theory of money creation
The textbook theory of money creation
Most college textbooks on money and banking describe a model showing how banks create money. The reader should bear in mind that even if the model were true, there has not been any research that provided any social welfare justification for money creation by commercial banks.
Consider an economy where banks maintain 10% reserve ratios. A person with $100 deposits the money with bank A. Bank A then lends $90 to another person, who then deposits it in Bank B. Bank B lends 0.9 x $90 = $81 to a person who deposits it in Bank C. Total money created in the economy can be computed to be:
Therefore, according to this textbook scenario, the banking system has created additional $900 of inside money from an initial $100 deposit.
A logical problem with the standard explanation
A paper by the Bank of England, McLeay et al. (2014), identifies a logical problem with the standard explanation of money creation, namely, the that this explanation neglects to mention where the initial $100 came from.
The answer is that the person has probably received the $100 from her employer. But the employer had to get the $100 from somewhere, which means that the employer withdrew $100 from the business account. Therefore, the total net change in the money supply should be zero and not $100.
The main conclusion of that paper is that, contrary to the standard textbook assertion that "deposits create loans," the revised assertion should be that "loans create deposits." This means that, under the revised model, banks create even more money during economic booms, and contract faster during recessions, which explains why banks' money creation amplifies the business cycle.
The authors demonstrate their explanation with the following aggregate balance sheet of all commercial banks.
As the figure shows, new money and deposits are created at the moment the bank grants a loan to a customer. This type of deposit is often referred to as 'fountain pen money" created at the stroke of banks' pens when they approve loans. The former governor of the Bank of England King (2016) calls this process money "alchemy" (creating money from thin air).
"Mary Poppins" banks
There may be no better place to learn about the structural weakness of the current banking system than from watching the 1964 Disney classic movie entitled Mary Poppins. Dick Van Dyke, portraying a chairman of a bank who is a "giant in the world of finance," tries to convince the kids to hand him their tuppence for the purpose of opening a bank account. He sings:
If you invest
And you'll achieve that
sense of conquest
You see, Michael, you'll be part of
The old chairman ends his lecture by stating that "where stands the bank of England, England stands, and when falls the bank of England, England falls!" Eventually, the kids refuse to deposit their tuppence and create a panic leading to a run on the bank, so the kids' expectations become self-fulfilling.
