<p>So taken literally, the question is what happens to an economy when its money supply is reduced by 98%, and at the same time total lending shrinks by whatever proportion bank lending is of total lending in the economy (typically 1/3 or more).</p>

<p>In the short run, congratulations, you no longer have an economy. Nobody can pay their non-bank debts any more, because there isn´t enough money to pay them with. Bear in mind debt payments do not automatically adjust to changes in the money supply. That triggers a <a href="https://fraser.stlouisfed.org/docs/meltzer/fisdeb33.pdf">debt cascade</a> causing wide-spread company failure. The accompanying impact on all prices causes massive disruption in the supply chain, because everything in the economy is now completely mis-priced relative to everything else. A 20% reduction in the liability money supply <a href="https://fraser.stlouisfed.org/docs/publications/bms/1914-1941/BMS14-41_complete.pdf">in the US in 1930-33</a> for example caused the price of food bought from farmers in some parts of the USA to be less than the cost of the fuel required to get the food to the market for sale. This event would clearly be far worse than that. Market based systems can and will adjust prices over time to compensate for money supply changes, but that´s the long term. It has been said that 'every civilisation is only 2 meals away from barbarism', and I´m afraid you just pushed yours over the edge. </p>

<p>In the long term, after a period of market exchanges being performed with cigarettes, and other money-substitutes, and those responsible for this mess being hunted down and dealt with appropriately, people will probably feel that fractional reserve banking wasn´t such a bad idea after all.

@Brythan I strongly suspect that banks would allow people to easily transfer their money to a form of investment account where it could be loaned out, the only difference is it would be labeled "investments" instead of "savings" and probably have higher withdrawal fees.

Thank you for you in-depth answer. The challenge I am having with it is that I was not asking about shrinking money supplies. As a few suggested in comments it's fairly possible to create 100% of money supplies pretty much in the same fashion as the remaining 2% (=M0) are created as money does not have intrinsic value - goods and services have. It costs nothing to create money supplies and my question pertains to the shift in who creates them. Not the quantity of it.

That´s an equally good question. Constant money - we simply don´t know. Were you to simply match the current monetary expansion rate of the country you´re in (they´re all different), then the simple monetary expansion effects should be the same. However the new money will probably end up somewhere different - at the moment it´s essentially channelled into that part of the economy which requires bank lending for financing - and that will be very noticeable. House prices will probably go down...

I think that you are ignoring the difficulty in lending money in a full reserve banking system.  The current system allows demand accounts (checking and savings) to have their balances loaned out.  The idea is that only a small reserve fraction is required to handle excess withdrawals (over deposits).  In a full reserve system, you can't loan out that money.  So where do you get money to loan?  Would all loans be securitized?  We can see how well that turned out last time.  That's why I'm thinking that this question is missing two prerequisite questions.

@Brythan - you're quite right, although that's not exactly how it works. Banks don't in practice lend out 'money' that they have on deposit. Rather, they create a quantity of deposits that exactly matches the quantity they are lending (minus cash). So yes, in a full reserve system (although if you read Fisher et. al., this isn't exactly what they meant by full reserve), a large amount of lending has effectively been removed from the economy. In my opinion, this would be disastrous - and I share your views on the ongoing problems with securitization -  but that paper is in preparation :)

<p>Here's a hypothetical society. </p>

<p>The currency is gold coins. These can't be created virtually or counterfeited. There's a limited number of them in our society. </p>

<p>I happen to have 1000 myself, and because I own them, I create a bank and I can lend them out. </p>

<p>If people deposit their coins into my bank, I can't lend those coins out. Therefore I have no reason to look after them for them, unless I start charging 'safe keeping' fees. </p>

<p>Because I only have 1000 coins to lend, but lots of people to lend to, I lend my coins to who's paying the highest <code>(interest rate * chance of paying the loan back)</code>. </p>

<p>I can't make a new loan until the old one is paid back. </p>

<p>This means that it's <em>much much much</em> harder for anybody to borrow money. They can either borrow money now and pay exorbitant interest, or they must save money before they spend it. </p>

<p>Somebody that has a great business idea, but needs the capital to fund it, needs to wait five years while saving money for it, or else he sells shares in his business. </p>

<p>I guess he's allowed to borrow the supplies he needs directly from the suppliers. But this means that the suppliers assume all the risk in the case that business fails. </p>

<p>Suppliers would subscribe to 'risk assessment' services who match ideal borrowers to the suppliers, since it's now the supplier holding the risk. </p>

<p>When someone purchases something with gold coins, the gold coins then sit the seller's vault doing nothing, as the seller doesn't need to spend the coins <em>right now</em> but may need to use them tomorrow, so he can't lend them out, unless he's doing some 'day to day' lending scheme, which would be hard for the borrower in this case to payback unless they had some surefire way to pay the loan back each day.</p>

Interesting approach but introducing gold standard slightly overshadows the main point - the only change we hypothetically make is abolishing FRB . Just that single change. Yes of course it would be much harder to borrow money but at the same time money would become a lot safer asset. No risk that amount of m1+ money in circulation will increase drastically.

<p>Some clarifications...</p>

<p>M0 is different than MB. M0 is just cash and I assume you meant MB.</p>

<p>If a bank can only lend what it has, what definitions of money and lending do you include?  A bank operates by mismatching short term debt (much of which is deposits) with long term assets.  An untenable situation regardless of the type of assets (deposits vs non-deposits).</p>

<p>If we stop say banks from mismatching say 0 second maturity deposits to long term assets, do we then stop 1 second debt?  1 day? 10 days? 100 days?</p>

<p>The other clarification to ask if if the open market would still function?</p>

<p>So say yes the open market would function, but banks must now back M1 demand deposits 100% with MB.</p>

<p>What would banks do?  They would no longer offer free checking.  Instead they would relabel their service to avoid the new requirements.  They could call them "power deposits".  They might yield .000000001% and maybe withdrawels might be limited to say one day after deposits.  Little would change under such a system.  The core concept of maturity mismatching is still creating problems for the economy and the Fed is still bailing the system out through the open market.</p>

<p>What would be a more practical solution?  Offer the public an alternative to private bank deposits.  Allow for public bank deposits (aka deposits directly at the Fed).  The Fed allows private banks to hold debt-free deposits with them...why not the public?  It would be a simple matter to let the Fed issue debit cards and checks for these accounts.</p>

<p>What about broad money?  Banks could be released from constant Fed bailouts because public deposits are no longer at risk...only investors are now.  Individuals who wanted to foolishly lend to banks without the backing of the Fed could do so if they REALLY wanted to, but few would as the banking system would burn up in a liquidity fire without Fed support to prop up maturity mismatching by constantly providing artificial levels of short term debt to the banking system.</p>

<p>What about outstanding debt?  The Fed could in the meantime introduce more MB into the economy to compensate for the collapse of higher monetary aggregates (by buying assets).</p>

<p>What are the long term implications? Imagine if the government let people counterfeit money...but ONLY if they bought couches.  What would be the result?  Couch prices would be higher than normal.  Well banks pretty much are only allowed to buy fixed income securities so interest rates are artificially low now, but without FRB interest rates would go up.  Not a bad thing though.  It would reward honest, non-bubble creating investment/savings.  There would be less inflation.  And there would be less need of borrowing to pay back all the FRB loans.</p>

<p>The national depository solution is IMO the only practical solution to fractional banking.  It would also allow for more gradual transition from FRB to non-debt backed deposits.  Here is an article on how it may work: <a href="http://wfhummel.cnchost.com/nationaldepositorysystem.html" rel="nofollow">http://wfhummel.cnchost.com/nationaldepositorysystem.html</a></p>

<p>Although there's a lot of important points in the other answers, there is something important missing:</p>

<p>Prohibiting FRB means that you cannot borrow to invest. Effectively, it means that you can't create debt contracts because in a debt contract you take somebody's money and promise to repay it, but <em>you don't keep the money</em>, instead, you use it for some type of investment. If borrowing is forbidden, other social mechanisms for intermediation would take its place, like issuance of shares. You would buy shares in the bank rather than open up a deposit account, much like investment banking used to be when i-banks were not levered.</p>

<p>I am by no means a financial expert, I do however believe such a system would collapse totally. I cannot prove it though.</p>

<p>Some figures:
American population: 350 million
Average american saving account: &lt;10'000$

That would give a possible total loan of 3.5 trillion
Fortune 1000 companies alone would require roughly 1.5 trillion. (6% of total market cap, 25% of market cap estimated as revenue, 25% of revenue estimated as required loan to get the company going)
There are over 30 million companies in US! <a href="https://www.bizjournals.com/albany/news/2019/04/11/number-of-businesses-in-the-united-states.html" rel="nofollow noreferrer">https://www.bizjournals.com/albany/news/2019/04/11/number-of-businesses-in-the-united-states.html</a>
I wonder how those 32 million (minus 1000 of the Fortune 1000) will continue to operate. After all even the bakery needs an oven to bake bread. But where will they get the money from? It's all gone, at least after we subtract some more money for property</p>

<p>That would leave 2 trillion for property
Average mortgage 100'000, that'll give us 20 million houses
Currently over 200 million people own property: <a href="https://www.statista.com/statistics/184902/homeownership-rate-in-the-us-since-2003/" rel="nofollow noreferrer">https://www.statista.com/statistics/184902/homeownership-rate-in-the-us-since-2003/</a>
So 90% of those would live where exactly? Cause also houses for rent would not exist, as the money has gone!</p>

<p>New roads? I beg you pardon, from which money?
Hospitals? Are you kidding?
Schools? Teach your kids yourself!
Food? Well 20 million people have their own garden, the rest will start a war to fight for what's left
Firearmy? Please, one does not play with fire, or "help yourself"
Police? I hope you have enough money to buy a gun and defend yourself
Cars? c'mon.. climate change is upon us... walk!
Stock market? uh? what's that? we don't have money for something like that</p>

Interesting approach indeed.Challenges with your approach? There are a few. 1) There is no intrinsic value in money, i.e., nobody wants money for money. No. People want goods and services, not money. Because of fractional reserve and ever decreasing purchasing power, money is like a hot potato - nobody wants to hold it. You only keep as low as you have to and immediately exchange the rest for either goods or services.
And 2) issuing money is bearing hardly any cost - anybody can issue money at near zero cost. US government can issue their own currency without any debt if they wanted.

With so many negative traits of fractional reserve like delegation of responsibility on taxpayers due to lack of insurance; practical dispossession of the whole classes of people that are not participating in the fractional reserve scheme by not having any debts, there are a few positives regarding resources management, that is  better management, higher risk taking and thus better utilisation of resources.

When we had a gold standard, we needed fractional reserve banking to give more control over money creation.  Without a gold standard, we can create money without fractional reserves or starting a gold mine.  It's not the 1800s anymore.

@matcheek  The effect on mortgages, interest rates, etc. depends heavily on how credit would be offered without fractional reserves.  That's why this is over-broad.  It skips directly over an intermediate question, so you have to answer the implied question and then answer the questions that arise to get to the answers that you want.  Intermediate questions:  How do you switch from a fractional reserve system to full reserves?  How do you offer credit in such a full reserve system?  Only then can you start answering questions on mortgages and interest rates.

### Answer by username_6 on 2014-12-04. Score: 15

There is a long standing problem in most discussions of Fractional Reserve Banking (FRB), around the precise definition of money. Cash money (that is M0) is an asset on the banking system balance sheet, while deposit money (the liability) is the money that is created by lending.

Ever since the introduction of cheques specifically, and in general the ability to make direct transfers between two deposit accounts, deposit money has been the de facto form of money that is used in the economy. Cash money is maintained at a fractional reserve of deposits (it used to be a regulator of total deposits and lending, but in practice this isn´t the case anymore), and used primarily for inter-bank liquidity settlements, as transfers occur between bank accounts at different banks. Reserve requirements are now down to 2% or less in most countries.

So taken literally, the question is what happens to an economy when its money supply is reduced by 98%, and at the same time total lending shrinks by whatever proportion bank lending is of total lending in the economy (typically 1/3 or more).

In the short run, congratulations, you no longer have an economy. Nobody can pay their non-bank debts any more, because there isn´t enough money to pay them with. Bear in mind debt payments do not automatically adjust to changes in the money supply. That triggers a [debt cascade](https://fraser.stlouisfed.org/docs/meltzer/fisdeb33.pdf) causing wide-spread company failure. The accompanying impact on all prices causes massive disruption in the supply chain, because everything in the economy is now completely mis-priced relative to everything else. A 20% reduction in the liability money supply [in the US in 1930-33](https://fraser.stlouisfed.org/docs/publications/bms/1914-1941/BMS14-41_complete.pdf) for example caused the price of food bought from farmers in some parts of the USA to be less than the cost of the fuel required to get the food to the market for sale. This event would clearly be far worse than that. Market based systems can and will adjust prices over time to compensate for money supply changes, but that´s the long term. It has been said that 'every civilisation is only 2 meals away from barbarism', and I´m afraid you just pushed yours over the edge.

In the long term, after a period of market exchanges being performed with cigarettes, and other money-substitutes, and those responsible for this mess being hunted down and dealt with appropriately, people will probably feel that fractional reserve banking wasn´t such a bad idea after all. Some form of Germany Year 0 event will take place and the banking system will be restarted. Since all debt was effectively discharged during the "unfortunate event" the next few decades will probably be referred to as a golden age. By the survivors.

If instead we assume that rather than reducing the money supply (which we know is a bad idea), the banking system is instead converted so that there is no fractional reserve lending, asset cash is injected to replace debt, and maintain the current quantity of deposits. All deposits in the system are simply held constant from this point on, and you now have a constant money supply economy.

As a side note, everybody now has to pay for their bank accounts, because since banks are no longer lending institutions, they need a revenue source to fund their operations. Quite a large revenue source - ATM networks aren´t cheap.

The problems caused by a sudden drop in total lending are still present. In practice this will disrupt the economy in the short term, but hopefully not quite as badly as in the previous scenario.

The short answer though, is we simply don´t know how a constant money economy behaves in practice. There hasn´t been a constant money economy since fractional reserve banking was invented, and that´s at least 3-400 years now (depending where you put goldsmith banking in the banking continuum, and what country you´re in).

A lot of financial statistics would probably start looking very strange, since even correcting for CPI doesn´t adequately control for the impact monetary growth has on price measurements. It´s possible that the economy would settle down after a few years as everything adjusts around the constant money supply - that´s essentially the general equilibrium theory argument. It´s also entirely possible that the growth in the money supply that FRB provides over time makes it easier for adjustments to occur - a lot of arguments in favour of small positive inflation amounts essentially revolve around this - and that a bunch of issues we didn´t previously know about emerge and cause new problems.

While this is very much an open research question, it´s interesting to note that a side effect of some of the recent Basel 3 regulatory changes is that at least for the last couple of years, several countries including the UK have experienced stable money supplies.

So yes, in a full reserve system (although if you read Fisher et. al., this isn't exactly what they meant by full reserve), a large amount of lending has effectively been removed from the economy. In my opinion, this would be disastrous - and I share your views on the ongoing problems with securitization -  but that paper is in preparation :)  
> **username_7**: @username_4 I strongly suspect that banks would allow people to easily transfer their money to a form of investment account where it could be loaned out, the only difference is it would be labeled "investments" instead of "savings" and probably have higher withdrawal fees.

Here's a hypothetical society.

The currency is gold coins. These can't be created virtually or counterfeited. There's a limited number of them in our society.

I happen to have 1000 myself, and because I own them, I create a bank and I can lend them out.

If people deposit their coins into my bank, I can't lend those coins out. Therefore I have no reason to look after them for them, unless I start charging 'safe keeping' fees.

Because I only have 1000 coins to lend, but lots of people to lend to, I lend my coins to who's paying the highest `(interest rate * chance of paying the loan back)`.

I can't make a new loan until the old one is paid back.

This means that it's *much much much* harder for anybody to borrow money. They can either borrow money now and pay exorbitant interest, or they must save money before they spend it.

Somebody that has a great business idea, but needs the capital to fund it, needs to wait five years while saving money for it, or else he sells shares in his business.

I guess he's allowed to borrow the supplies he needs directly from the suppliers. But this means that the suppliers assume all the risk in the case that business fails.

Suppliers would subscribe to 'risk assessment' services who match ideal borrowers to the suppliers, since it's now the supplier holding the risk.

When someone purchases something with gold coins, the gold coins then sit the seller's vault doing nothing, as the seller doesn't need to spend the coins *right now* but may need to use them tomorrow, so he can't lend them out, unless he's doing some 'day to day' lending scheme, which would be hard for the borrower in this case to payback unless they had some surefire way to pay the loan back each day.

> **username_0**: Interesting approach but introducing gold standard slightly overshadows the main point - the only change we hypothetically make is abolishing FRB . Just that single change. Yes of course it would be much harder to borrow money but at the same time money would become a lot safer asset. No risk that amount of m1+ money in circulation will increase drastically.

Some clarifications...

M0 is different than MB. M0 is just cash and I assume you meant MB.

If a bank can only lend what it has, what definitions of money and lending do you include? A bank operates by mismatching short term debt (much of which is deposits) with long term assets. An untenable situation regardless of the type of assets (deposits vs non-deposits).

If we stop say banks from mismatching say 0 second maturity deposits to long term assets, do we then stop 1 second debt? 1 day? 10 days? 100 days?

The other clarification to ask if if the open market would still function?

So say yes the open market would function, but banks must now back M1 demand deposits 100% with MB.

What would banks do? They would no longer offer free checking. Instead they would relabel their service to avoid the new requirements. They could call them "power deposits". They might yield .000000001% and maybe withdrawels might be limited to say one day after deposits. Little would change under such a system. The core concept of maturity mismatching is still creating problems for the economy and the Fed is still bailing the system out through the open market.

What would be a more practical solution? Offer the public an alternative to private bank deposits. Allow for public bank deposits (aka deposits directly at the Fed). The Fed allows private banks to hold debt-free deposits with them...why not the public? It would be a simple matter to let the Fed issue debit cards and checks for these accounts.

What about broad money? Banks could be released from constant Fed bailouts because public deposits are no longer at risk...only investors are now. Individuals who wanted to foolishly lend to banks without the backing of the Fed could do so if they REALLY wanted to, but few would as the banking system would burn up in a liquidity fire without Fed support to prop up maturity mismatching by constantly providing artificial levels of short term debt to the banking system.

What about outstanding debt? The Fed could in the meantime introduce more MB into the economy to compensate for the collapse of higher monetary aggregates (by buying assets).

What are the long term implications? Imagine if the government let people counterfeit money...but ONLY if they bought couches. What would be the result? Couch prices would be higher than normal. Well banks pretty much are only allowed to buy fixed income securities so interest rates are artificially low now, but without FRB interest rates would go up. Not a bad thing though. It would reward honest, non-bubble creating investment/savings. There would be less inflation. And there would be less need of borrowing to pay back all the FRB loans.

The national depository solution is IMO the only practical solution to fractional banking. It would also allow for more gradual transition from FRB to non-debt backed deposits. Here is an article on how it may work: <http://wfhummel.cnchost.com/nationaldepositorysystem.html>

Although there's a lot of important points in the other answers, there is something important missing:

Prohibiting FRB means that you cannot borrow to invest. Effectively, it means that you can't create debt contracts because in a debt contract you take somebody's money and promise to repay it, but *you don't keep the money*, instead, you use it for some type of investment. If borrowing is forbidden, other social mechanisms for intermediation would take its place, like issuance of shares. You would buy shares in the bank rather than open up a deposit account, much like investment banking used to be when i-banks were not levered.

I am by no means a financial expert, I do however believe such a system would collapse totally. I cannot prove it though.

Some figures:
American population: 350 million
Average american saving account: <10'000$
<https://www.cnbc.com/2019/03/11/how-much-money-americans-have-in-their-savings-accounts-at-every-age.html>
That would give a possible total loan of 3.5 trillion
Fortune 1000 companies alone would require roughly 1.5 trillion. (6% of total market cap, 25% of market cap estimated as revenue, 25% of revenue estimated as required loan to get the company going)
There are over 30 million companies in US! <https://www.bizjournals.com/albany/news/2019/04/11/number-of-businesses-in-the-united-states.html>
I wonder how those 32 million (minus 1000 of the Fortune 1000) will continue to operate. After all even the bakery needs an oven to bake bread. But where will they get the money from? It's all gone, at least after we subtract some more money for property

That would leave 2 trillion for property
Average mortgage 100'000, that'll give us 20 million houses
Currently over 200 million people own property: <https://www.statista.com/statistics/184902/homeownership-rate-in-the-us-since-2003/>
So 90% of those would live where exactly? Cause also houses for rent would not exist, as the money has gone!

New roads? I beg you pardon, from which money?
Hospitals? Are you kidding?
Schools? Teach your kids yourself!
Food? Well 20 million people have their own garden, the rest will start a war to fight for what's left
Firearmy? Please, one does not play with fire, or "help yourself"
Police? I hope you have enough money to buy a gun and defend yourself
Cars? c'mon.. climate change is upon us... walk!
Stock market? uh? what's that? we don't have money for something like that

> **Comments:**
> **username_0**: Interesting approach indeed.Challenges with your approach? There are a few. 1) There is no intrinsic value in money, i.e., nobody wants money for money. No. People want goods and services, not money. Because of fractional reserve and ever decreasing purchasing power, money is like a hot potato - nobody wants to hold it. You only keep as low as you have to and immediately exchange the rest for either goods or services. And 2) issuing money is bearing hardly any cost - anybody can issue money at near zero cost. US government can issue their own currency without any debt if they wanted.  
> **username_0**: With so many negative traits of fractional reserve like delegation of responsibility on taxpayers due to lack of insurance; practical dispossession of the whole classes of people that are not participating in the fractional reserve scheme by not having any debts, there are a few positives regarding resources management, that is  better management, higher risk taking and thus better utilisation of resources.  
> **username_11**: Totally agree. Yet without it we’d still be living in the Stone Age. And as a matter of fact I enjoy having a life expectancy of over 70 years.   But I agree that maybe it’s time for a change.
