The Swiss central bank and Sovereign Money.

Thomas Jordan, Chairman of the Governing Board Swiss National Bank published an article recently entitled “How money is created by the central bank and the banking system”. Actually the article is the transcript of a speech.

“Sovereign Money” is a quite widely used phrase which means the same as “full reserve” banking, or what Milton Friedman called “100% reserve” banking (which Friedman supported).

I have no criticisms of the first half or so of Jordan’s article: it sets out the basics about how central and commercial banks work, and in very clear language. (I’ll refer to commercial banks henceforth simply as “banks”).

But there are several points in the second half I don’t agree with. Under the heading “Why the image of creating money out of thin air is misleading”, Jordan starts by criticising the idea that banks are “privileged” in any way through reason of their ability to create money. The answer to that is that banks, at least under UK law, are very definitely in a privileged position as explained by Richard Werner in his article “How do banks create money, and why can other firms not do the same?” (published by Science Direct, 2014).  That is, banks can lend on money deposited with them, but no other type of firm can do that. And it is precisely that lending on of customers’ money that enables banks to create money.

As to the law in countries other than the UK, I’m no expert on that, but it is bound to be ROUGHLY similar to UK law: for example, I doubt lawyers in other countries are allowed to lend out clients’ money deposited with them (except in as far as depositing money at a reputable bank equals a loan to that bank).

Another way in which the ability to create money puts banks in a privileged position is that that ability enables them to come by money in a costless manner (unlike non-bank corporations) and hence artificially expand the size of the bank industry. That is, non-bank corporations and firms can only obtain money by borrowing it or earning it. Banks have a third and entirely costless way: creating or “printing” money. As Joseph Huber and James Robertson explain on p.31 of their work “Creating New Money”, lending out money you have created yourself at no cost is more profitable than lending out money you have had to earn or borrow. For more on that see my article “The Bank Subsidy No One Mentions”.

Indeed, the proto-bankers in Britain in the 1600s and 1700s discovered that lending out “home made money” in the form of receipts for non existent gold was cheaper than lending out receipts for gold which actually existed.

Next, under the heading “Comments on Sovereign Money” (p.7), Jordan makes three criticisms of Sovereign Money. First he says “the switch to Sovereign Money would be a move away from the historical distribution of responsibilities between the central bank and commercial banks. In this tried and tested two tier system, commercial banks compete with one another to supply households and companies with credit and liquidity, while the central bank acts as the bankers’ bank and conducts monetary policy.”

Well certainly under Sovereign Money, the split of responsibilities as between central banks and governments does change a bit. But the idea that any change in responsibilities is inherently undesirable is not a brilliant argument. Moreover, advocates of full reserve were making it plain some time ago that a change in responsibilities was  involved, e.g. see here. So the “change in responsibilities” point is not news.

As for “tried and tested”, that rather implies that banks have “passed the test” so to speak. In view of the 2007/8 bank crisis, it might be more appropriate to say “tried and found to be severely wanting, as demonstrated in the 2007/8 bank crisis.”

Also it is not true to say banks cease to “compete with one another to supply households and companies with credit…”. The basic change when switching to Sovereign Money is that banks have to fund their loans via equity rather than via debt (e.g. deposits). Apart from that, they compete as they always did.

Monetary policy.

As for the idea that the central bank no longer “conducts monetary policy”, that is not entirely true either. Certainly under Sovereign Money, monetary policy becomes less potent in that interest rate adjustments become less effective.  However, under Sovereign Money, central banks and governments still manage stimulus, which of necessity is at least to some extent monetary in nature.

To be more exact, assuming the sort of stimulus advocated by Positive Money is implemented instead, i.e. having central bank and government create new money and spend it (and/or cut taxes) that form of stimulus has a monetary element. That is when central bank and government create and spend fresh money, there is an initial fiscal effect: jobs are created for example in state schools or via building state owned infrastructure. Second, that spending results in the private sector’s stock of money rising. That’s monetary policy of a sort. (Incidentally Positive Money is a UK based organisation that backs the Sovereign Money idea.)

Next, Jordan says that Sovereign Money , “..calls for the Swiss National Bank to guarantee the supply of credit to the economy by financial services providers. In order to carry out this additional mandate, the SNB could provide banks with credit, probably against securitised loans. Depending on the circumstances, the SNB would have to accept credit risks onto its balance sheet and, in return, would have a more direct influence on lending. Such centralisation is not desirable. The smooth functioning of the economy would be hampered by political interference, false incentives and a lack of competition in banking.”

That idea, namely that the central bank should oversee the total amount of credit offered, and boost it if necessary is actually an OPTIONAL EXTRA, at least under Positive Money’s system.  Moreover, it’s an optional extra I don’t care for, thus I agree with Jordan in a sense there. Put another way, I see nothing wrong with simply insisting that loans are funded via equity, and then leaving it to the market to sort out.

Moreover, the idea that economists, whether working for the central bank or not, have superior judgement to the free market is very debatable. For example is the amount of lending to SMEs under the existing system adequate or not? There are arguments both ways on that one.

Interest rates would rise?

Jordan’s second criticism starts: “…Sovereign Money limits liquidity and maturity transformation as banks would no longer be able to create deposits through lending. Sovereign Money thus restricts the supply of liquidity and credit to households and companies. The financing of investment in equipment and housing would likely become more expensive.”

Well the first problem with that idea is that arguably interest rates are too low, with the result that we have excessive amounts of debt. Certainly if the popular idea that debts are excessive is correct, then a rise in interest rates would do no harm.

Another big potential problem with Jordan’s latter claim is the Modigliani Miller theory. According to the MM, the cost of funding a bank, or indeed any corporation, is not influenced by the method of funding. I.e. according to MM, funding via equity is no more expensive than funding via deposits. MM does have its critics, but I’ve been through the criticisms and I’m not impressed. (See section 1.4g here)

As for the point that Sovereign Money “limits maturity transformation”, I suggest that is an understatement. I.e. the truth is that Sovereign Money means the end of maturity transformation. Reason is that maturity transformation and money creation by private banks are the same thing. So if private money creation is banned, then so too is maturity transformation. Reasons for that are as follows.

Starting with the simplest possible loan, i.e. a loan from Mr A to Ms B, A loses access to his money until B repays it. In theory A can sell the loan, but for a person to person loan like that, A would not get a good price for the loan. That is, there no very effective way for A to transform his long term loan into a short term one (i.e. engage in  maturity transformation).

In contrast, a bank can take deposits from dozens of people, lend the money on to B, at the same time as promising the depositors they can have their money back whenever they want. I.e. the sort of long term loan that is involved where A lends to B, in the case of bank, involves funding a long term loan via loans to the bank (i.e. deposits) which have a time to maturity of zero. And a liability of a bank which has zero maturity is money.

To summarise, the bank lends £X to B, so B has the use of the money, while the depositors who deposited £X with the bank still have access to their £X. Lo and behold £X has been turned into £2X.

Disallowing maturity transformation certainly has a deflationary effect, but that doesn’t matter because the state can print and spend any amount of money it wants into the economy to compensate.

So Jordan’s claim that “Sovereign Money thus restricts the supply of liquidity and credit to households and companies” isn't quite right. That is, the amount of “liquidity” is not affected in that the loss of commercial bank created money is approximately compensated for by an increased supply of state issued money. Secondly, there is less credit creation, i.e. less lending, but that doesn’t matter in that everyone has a larger stock of base money and thus they do not need to borrow so much. In short, Sovereign Money results in less loan based economic activity, and more non-loan-based activity.

The third criticism – financial stability.

Jordan’s third criticism starts “Third, it would be naive to hold out too much hope on the financial stability front Investors and borrowers will always make misjudgements. A switch to Sovereign Money would thus not prevent harmful excesses in lending or in the valuation of stocks, bonds or real estate.”

Well the advocates of Sovereign Money have never claimed that by some magic, creditors’ ability to assess debtors is transformed. In fact that ability will remain much the same.

One of the crucial differences between a Sovereign Money system and the existing system is that however bad those misjudgements, a bank cannot possibly go bust as a result. E.g. if a bank’s loans turn out to be worth say 75% of book value (and that’s far worse than anything that happened to large banks during the recent crisis) all that happens is that the value of the shares that fund the bank drop to about 75% of book value. It is quite common for shares of non-bank  corporations to drop to 75% of the value over a period of weeks or months, either  because of a general fall in stock exchange indices, or because of poor performance by particular corporations. That sort of event does not cause finance crises.

Next, in his third criticism of Sovereign Money, Jordan claims “So the Sovereign Money initiative, with its focus on payment transaction accounts does not resolve the too big to fail issue.” My answer to that is: “yes it does”. As explained just above, under Sovereign Money, banks cannot fail. That solves the too big to fail problem!

Jordan then says, “The initiative (i.e. Sovereign Money) requires that the SNB manage the money supply, an idea we abandoned some 20 years ago. Today, the SNB steers monetary conditions via money market rates, a strategy which has served it well over the years. A switch to monetary targeting would therefore be an unnecessary step backwards from our perspective.”

Well I’m not acquainted with all the details of the Swiss Sovereign Money movement, but in the case of the equivalent movement in the UK, i.e. Positive Money, interest rate adjustments are not replaced SIMPLY with adjustments to the money supply. What happens is that the state, to repeat, creates and spends new money (and/or cuts taxes) when stimulus is needed. And the mere fact of that spending (e.g. on infrastructure, state schools, etc) creates jobs. I.e. there is an immediate fiscal effect there, followed by a longer term monetary effect stemming from the increased money supply. As distinct from increased public spending, government can choose to cut taxes, an option that a relatively right wing government might prefer.


Jordan then queries the reversibility of stimulus, Sovereign Money  style, and certainly that’s a valid point to raise. That’s in his next paragraph, starting “Another problem for monetary policy would arise….”.

There are actually two or three possible forms of reversibility under Sovereign Money. First, all economies have a form of built in and totally automatic form of reversibility via the 2% inflation target. That is, if inflation is running at 2% a year, then the real value of the country’s stock of base money and government debt declines at 2% a year.

At some point that decline is guaranteed to lead to the private sector having what it regards as an inadequate stock of the latter two assets (which are actually so similar that they almost amount to the same thing, as explained by Martin Wolf in the Financial Times). The private sector will then begin to save, and as Keynes pointed out via his “paradox of thrift” metaphor, that leads to deficient demand, at which point, far from reversibility being needed, the opposite, i.e. stimulus is needed.

A second possible form of reversibility is tax. As explained above, under Sovereign Money, stimulus can be implemented by cutting taxes. Likewise, a “reverse” can be implemented by raising taxes (and “unprinting” the money collected).

Third, interest rates can be raised. As explained above,  interest rate adjustments do not have as big an effect under Sovereign Money as under the existing system, but they would nevertheless have a  finite effect.


Jordan’s next objection to Sovereign Money (para starting “Finally, a more general….”) is that there would be “uncertainty” and “turmoil” if Switzerland shifted to a Sovereign Money system while other countries did not.

Certainly it would be better for a significant group of countries, like the EU, to make the switch rather than just one country make the switch. But there are Sovereign Money movements in most countries nowadays, thus if the basic Sovereign Money idea is valid, then hopefully several countries will make the switch at the same time. Put another way, the fact that a solution to a problem is most effective where several countries or all countries adopt the solution at the same time is not a good argument against that solution.

Also Jordan does not spell out exactly what the above “uncertainty” and “turmoil” would consist of. Well here is a suggestion: where one country alone implements Sovereign Money, that could raise interest rates, i.e. make loans more expensive, which would be an artificial advantage for foreign banks.

Well the answer to that is that loans are relatively cheap under the existing system because under the existing system banks are subsidised. First there is the well known TBTF subsidy. The TBTF subsidy derives from the belief that under no circumstances can large banks be allowed to fail, and to that end, the Fed loaned around $600bn at a near zero rate of interest for around 18months to various banks. The $600bn comes from figure 11 here. As to the near zero rate, I have not been able to confirm the average rate, but all the individual loans made by the Fed that I’ve looked at were at either a zero or a near zero rate. That compares to the 10% that Warren Buffet charged Goldman Sachs at the height of the crisis for a $5bn loan, so 10% is presumably the realistic rate approximately.

And for another example of the sort of subsidy that bankers manage to wheedle out of politicians, the UK government has always provided deposit insurance for banks for free till quite recently.

Now if some foreign country wants to provide goods or services at an artificially low rate, why not let them? I.e. if Switzerland or any other country implements Sovereign Money, and finds that foreign owned banks eat into the market in the Switzerland or wherever, what is there to worry about? To take an extreme example, if any country out there wants to sell me a brand new car for $1, please get in touch with me.

Why don’t base money backed accounts already exist?

Finally, in the first paragraph of his conclusion, Jordan asks why banks have not already set up CB money backed accounts if such accounts are so wonderful.

Well the first answer to that is that in some countries, governments (rather than banks) actually have set up such accounts. For example there is National Savings and Investments in the UK. And NSI accounts are quite popular in the UK. NSI does not offer the full range of services offered by a normal bank, but it comes quite close to doing so.

Second, Jordan points to the fact that banks under the existing system offer everything a bank customer could want: interest on deposited money plus total security.

Well the flaw in that argument is that the security only comes thanks to taxpayers standing behind bank accounts. Put another way, taxpayers enable depositors to have their cake and eat it: depositors can have their money fund relatively risky loans, with taxpayers picking up the pieces when that goes wrong. Why should any depositor say no to that arrangement?

If taxpayers compensated me for losses at the local casino, but let me keep the winnings when I won, I’d be in the local casino every other night of the week.

You pay extra interest on your mortgage just to enable the central bank to adjust interest rates.

The reason you pay an unnecessarily large amount of interest on your mortgage comes at the end of this article. To explain the reasons, it is necessary to explain something about MMT and interest rates. 

According to Simon Wren-Lewis in an article entitled  “Do Trump’s deficits matter?”, MMTers do no approve of interest rate adjustments. As he says:

“…what MMT actually says is that inflation should determine what the deficit should be. If inflation looks like staying below target you can and should have a larger deficit, and vice versa. The reason they say that is that they think the central bank, in changing interest rates to control inflation, is wasting its time, because they believe rates do not have a predictable impact on demand and inflation.”

Well speaking as someone who reads and leaves more comments on MMT blogs than about 99.999% of the population, that’s not my impression. However, MMTers are a diverse lot, and it’s often not entirely clear what they think as a group.

My impression is that MMTers don’t think much of interest rate adjustments because they tend to believe in a permanent zero interest rate, or at least that a zero rate should always be the objective, with occasional interest rate rises being used only in emergencies. Milton Friedman advocated that policy in his 1948 American Economic Review paper. See para starting “Operation of the proposal…”.

Also, MMT’s founder, Warren Mosler advocated a permanent zero rate in this Huffington article (2nd last para), and here.

One reason for favoring a permanent zero rate is as follows. The private sector and the banking system in particular need a supply of base money. And that need is such that the private sector will willingly hold a stock of that money without being offered any reward for doing so. I.e. no interest needs to be paid.

But if the state issues too much of that money (i.e. runs too large a deficit for too long), then private sector entities will try to spend away the excess, and inflation will ensue, unless the state induces the private sector to hold onto that excess stock by offering interest on it.

But what’s the point of doing that? I.e. what’s the point, to put it figuratively, of inducing people to keep large wads of £10 notes under their mattresses, and inducing them not to spend that money by offering interest on it? This is a farce. It amounts to rewarding hoarders with money extracted from taxpayers.

It also results in everyone with a mortgage paying more interest than they need, just to enable central banks to adjust demand by adjusting interest rates. If monetary policy (i.e. interest rate adjustments) were VASTLY MORE EFFICIENT than fiscal policy when it comes to controlling demand, then there might be an argument for imposing that cost on mortgagers. But the evidence, far as I can see, is that interest rate adjustments do not work in a particularly quick, and predictable way, plus there are some who argue they don’t even have much effect.

No housing shortage in Britain?

It seems to be fashionable to argue that high house prices in the UK are not down to a shortage of houses. A quick read thru those sort of arguments normally reveals some nonsense thinking. This article is typical. It’s by Ian Hulheirn, Director of Consulting at Oxford Economics and former HM Treasury economist. (Article title: "Part I: Is there really a housing shortage".

His first argument is that because there are 5% more houses than households now as compared 3% 25 years ago that therefor there is no housing shortage.

Well now real incomes have increased during that period which can reasonably be expected to result in households demanding LARGER houses, and in more people demanding second homes. Plus there are more single person households than 25 years ago, and single people tend to demand more square meters of housing that the typical husband, wife and two kids household.

In short, it is reasonable to assume demand has risen. As to supply, the average value of land with planning permission to build on is £6million per hectare according to this source. That compares to around £20,000 for land without planning permission.  If that doesn’t indicate an artificial shortage of land to build on, then what does?

UK government gets more money via borrowing than from tax??

Well that’s the claim made by Ann Pettifor in an article entitled “Do tax revenues finance government spending? To quote, she says:

“…governments do not finance their investments, or even their activity, from tax revenues. Most of the government’s big expenditures are financed via the issuance of gilts – government bonds.”

Actually it’s the other way round, to put it mildly: i.e. governments get vastly more from tax than they do from borrowing. Reasons and calculations are as follows.

The first slight problem involved in quantifying things in this area is that the amount of borrowing governments do varies hugely depending on whether the economy is in recession, or the opposite, i.e. overheating. Thus to get a rough idea as to how much the UK government gets from borrowing and tax, I’ll take a relatively long period, that is, 1965 to the present: just over 50 years.

I’ve actually chosen that particular period because the debt/GDP ratio was 90% at the start and at the end of that period. (See first and second charts below) I.e. I’ve chosen that period because it keeps things simple. That might seem a cheat, but actually as you see by the end of this article, the actual amount of cheating is negligible. (Charts are taken from this site.)

Next, we need to compare real GDP in 1965 with GDP in 2017. According to this source, UK GDP expanded about two and a half times in real terms between 1965 and 2017.

Thus the increase in government borrowing between 1965 and 2017 was 0.9(2.5-1.0)=1.36x(1965GDP). Thus over that 52 year period, government got an amount of money from borrowing each year which on average equaled 1.36/52 times 1965GDP, which comes to 0.026 times 1965GDP: about 1/40th of GDP.

As to the proportion of GDP allocated to public spending, that’s hovered around 40% for a long time – see chart here.

So to summarise, 40% of GDP is allocated to public spending, and as for the money to fund that that comes from borrowing, that’s about 2.6% of GDP. 40/2.6= about 15. So about 1/15th of public spending is funded via borrowing, with the rest (over 90%) necessarily coming from tax.

Returning to the question as to how much of a cheat is involved in  choosing the period 1965 to 2017, the answer is: “not much”. That’s because one could go back another 50 years or so to around 1918 when the debt was also around 90% of GDP. (See above chart). That would make the total period a century: hardly unrepresentative.

Conclusion: the amount of money government gets from tax is roughly fifteen times what it gets from borrowing – unless I’ve dropped a clanger, which is not impossible...:-)

Warren Mosler’s bank reform ideas.


Warren Mosler produced some ideas for bank reform in a Huffington article in 2011. Title of the article is “Proposals for the banking system.”

While I agree with many of WM’s ideas (e.g. I support MMT which I think he founded), I’m not sure about his ideas on bank reform. The basic weakness in his proposals is that they amount to a subsidy of private banks. For example he argues that deposit insurance should be funded by taxpayers, not as at present, by commercial banks. (Incidentally WM spent much of his career working in the financial sector, so that may help explain his sympathetic attitude to that sector.)

Deposit  insurance.

Anyway, the first paragraph reads, “U.S. banks are public/private partnerships, established for the public purpose of providing loans based on credit analysis. Supporting this type of lending on an ongoing, stable basis demands a source of funding that is not market dependent. Hence most of the world’s banking systems include some form of government deposit insurance, as well as a central bank standing by to loan to its member banks.”

The second half of that para suggests that the purpose of deposit insurance is to ensure borrowers’ access to credit is not interrupted. In fact the basic purpose of deposit insurance is as per the description on the tin: it’s to insure deposits.

Indeed the failure of one or two small or medium size banks would not seriously interrupt borrowers’ access to credit: they can simply apply to other banks for loans. Obviously if the bank you normally deal with gets into trouble that may involve a finite interruption to your access to credit, but other banks are not going to turn you away when you apply for credit: no bank or any other business turns down extra sales.

In contrast, there is the possibility of the entire bank system collapsing, as seemed likely in the recent crisis. That clearly would interrupt borrowers’ access to credit. But that problem is not dealt with via deposit insurance in the normal sense of the word: it’s dealt with by central bank “lender of last resort” facilities (mentioned in WM’s above para).

Now the big problem with last resort loans is that while such loans are supposed to be at Walter Bagehot’s famous “penalty rate”, in the real world (no doubt party due to political pressure and bribes paid by banksters to politicians) the actual rate is a sweetheart rate, to put it mildly. The actual rate for the hundreds of billions worth of loans made by the Fed to banks in the recent crisis was near enough zero, which is a MONSTER subsidy for private banks. As it explains in the introductory economics text books, GDP is not maximised where an industry is subsidised, unless there is a good social case for a subsidy, as there is for example in the case of kid’s education.

WM returns to the question as to how to treat large banks in trouble later in his article. I’m dealing with his points in the order in which they appear in his article, so I’ll deal with his other points about large banks in trouble a few paragraphs hence.

100% reserves.

WM’s next para contains a slight mistake where it says “No bank can operate with 100% reserves.” Well that depends on your definition of the word “bank”. If you mean an institution which funds loans via deposits, then WM is correct. On the other hand there is such a thing as “100% reserve banking” (advocated by Milton Friedman and others). Under that system, deposits are all lodged at the central bank, while loans are funded via equity. (That’s “deposits” in the sense of: “money which is supposed to be totally safe”.)

A few sentences later, WM says “The hard lesson of banking history is that the liability side of banking is not the place for market discipline. Therefore, with banks funded without limit by government insured deposits and loans from the central bank, discipline is entirely on the asset side.”

Well the first problem with that idea is that WM does not provide any actual examples of “discipline” being imposed via the liability side and that being a disaster. Moreover, every bank regulator in the World far as I can see believes that some regulation of the liability side of banks’ balance sheets is justified: for example all recent attempts to re-jig bank regulations involve increasing banks’ capital ratios, or at least discuss the possibility of increasing those ratios.

Eight restrictions.

Next, WM lists eight restrictions which he thinks should be imposed on banks, some of which I like and some not. For example he opposes “off balance sheet” stuff and quite right: the purpose of a balance sheet is to give an accurate picture of a corporation’s assets and liabilities at some point in time. Thus off balance sheet items are plain simple deception, far as I can see. I gather off balance sheet stuff is virtually banned in Spain.

In contrast, restriction No.5 is that US banks should not be allowed to lend offshore. That’s a strange idea: banking is very much an international business.

But more important than the merits of individual restrictions suggested by WM is the point that all these restrictions amount to a move in the direction of full reserve banking. Reasons are thus.

Under full reserve (or 100% reserves as Milton Friedman called it), entities which accept deposits cannot take any risks at all with those deposits: an idea which is entirely logical. A deposit is supposed to be totally safe, but that is plain incompatible with lending on deposited money because loaned out money is NEVER entirely safe.

As to risky activities under full reserve, those are funded via equity. Now WM is saying that entities funded by deposits or mainly via deposits should not be allowed to engage in sundry risky activities. That in turn means that those activities will inevitably be funded by other entities which are funded via equity.

So why not go the whole hog and just ban entities funded via deposits from all risky activities? Well the standard answer to that given by supporters of the existing bank system is that that ban would reduce the amount of credit creation: i.e. reduce the amount of money created by commercial banks. But there’s a simple answer to that: have the state supply whatever amount of money is needed to lubricate the economy, which is a job the state (i.e. central bank plus government) already does to some extent. (Roughly 10% of the money supply is currently central bank rather than commercial bank issued money.)

Moreover, as I explain here, the right that commercial banks to fund loans via deposits actually amounts to letting them print or “create” money, and that’s a subsidy of commercial / private banks. (My article is entitled “Taxpayers subsidise private money creation.” (Journal of Economics Bibliography).

Proposals for the FDIC.

The next section of WM’s article is entitled as above, i.e. “Proposals for the FDIC” and it consists of three items.

Item No.2 is odd: WM argues that deposit insurance should not be charged to banks, i.e. he claims that taxpayers in general should fund deposit insurance. There again, I imagine every bank regulator in the world disagrees with that idea.

In short, having taxpayers fund deposit insurance is a blatant subsidy of the bank industry. The shipping industry carries the cost of insuring its ships. Banks should act likewise.

Proposals for the Federal Reserve.

Under the heading “Proposals for the Federal Reserve”, WM says:

“The Fed should lend unsecured to member banks, and in unlimited quantities at its target fed funds rate, by simply trading in the fed funds market. There is no reason to do otherwise. Currently the Fed will only loan to its banks on a fully collateralized basis. However, this is both redundant and disruptive. The Fed demanding collateral when it lends is redundant because all bank assets are already fully regulated by Federal regulators.”

Well the first problem there is the latter sentence: if bank assets really were “fully regulated”, no bank would every make silly loans I assume (thought that depends on exactly what “fully regulated” means).

As to the idea that the Fed should lend at the Fed funds rate, the problem there is that that rate is a sweetheart rate given that the corporations doing the borrowing are in trouble. (Banks themselves charge relatively high rates to any customer which appears to be in  trouble, and quite right.)

For an idea of what would constitute a realistic free market rate for a large loan to a large bank during the recent crisis we need look no further than the $5bn loan made by Warren Buffet to Goldman Sachs in September 2008. The loan involved an interest rate of 10%. In contrast, the Fed funds rate at that date was around 2% and sank to 0% shortly afterwards. To put it mildly, there’s a bit of a difference there!

WM also claims banks should not have to provide collateral in exchange for such loans. In contrast Warren Buffet (as you’d expect) did demand collateral. To summarise, we seem to have three options here. First the ultra-generous treatment of banks advocated by WM. Second, there’s the less generous treatment actually implemented by the Fed during the recent crisis. Third, there is what might be called the “brutal free market” treatment advocated by Walter Bagehot and Warren Buffet.

To repeat, the standard view in economics is that market forces should prevail, unless there are very clear reasons for thinking otherwise. And certainly in the case of large banks, there appears to be a good “reason for thinking otherwise”, namely that if large banks are given the “Buffet” treatment during a crisis, that may drive banks to insolvency.

However that insolvency only arises because of the basic nature of the existing bank system, sometimes called fractional reserve banking. That system allows commercial banks to use debt (deposits and bonds) to fund loans. And that is simply asking for trouble: it involves having liabilities that are fixed in value combined with assets (i.e. loans) which can fall dramatically in value when it turns out that silly loans have been made.

The attraction of using debt to fund a bank (or indeed any business) is that debt holders demand a slightly smaller return on their money than shareholders. But if the corollary is that taxpayers have to rescue large banks periodically, then in effect we have a system where banks are allowed to reap extra profits by taking extra risks, while the taxpayer picks up the pieces when the risks do not pay off. That is a nonsensical arrangement.

A better system is one where banks have to use equity to fund loans: that way it’s impossible for banks to go insolvent. I.e. if a bank makes silly loans and it turns out the value of those loans is only say 80% of book value, all that happens is that the value of the equity falls to about 80% of book value. That bank does not go bust.

At the same time, depositors who want their money to be totally safe are offered accounts where relevant monies really are totally safe: the money is simply lodged with the central bank or government. And that is the 100% reserve system advocated by Milton Friedman and others.

That system may well mean interest rates rise, but assuming they rise to a genuine free market level, then GDP ought to be higher at that higher rate than at the ultra-low rates that have prevailed for the last decade. And as for any deflationary effect of higher interest rates, that is easily dealt with by running a larger deficit.

And finally, low interest rates are not an unmixed blessing. Low rates mean more loans and hence more debt: and every socially concerned do-gooder has been complaining about the excessive amount of debt for the last five years or so. Plus low rates tend to encourage bubbles.
