Transaction Taxes and Transparency

The City of London is in a stir over the EU proposal of a financial transactions tax. The great and the good are uniformly arrayed against such a tax. I am not so sure that it wouldn't be a good thing.

Here in Britain we now pay 20 per cent Value Added Tax on virtually everything we buy, except food, medicines and children's clothing. Yet the financial sector is exempt of any similar tax on transactions. This is patently unfair since approximately 5 pence of the 20 is required to finance the state bailouts of the financial sector. As a regressive and unfair tax, that is hard to beat.

In addition to raising revenues from an investment banking sector which has decimated public finances for a generation to come, a transaction tax might be a very good thing from an accountability and transparency perspective.

Those opposing say it would be anti-markets and drive trading offshore. Markets clearly do not work properly anymore at price discovery, liquidity aggregation or trade transparency. I rather think markets would work better if those participating had an economic stake in the transaction longer than a nanosecond, and a trading objective more durable than front-running real investors with HFT gaming.

More than that, a transaction tax would recognise that the state adds value to the market and deserves to be recompensed for that value. A huge part of the operational value of developed markets is derived from the rule of law. Taxing transactions would be recognising that each transaction benefits from the legal system which makes such a transaction valid and enforceable.

In my view, the way to make the transaction tax workable and cost-effective is to incentivise the reporting of transactions and the payment of tax. The way to do this is to legislate that transactions themselves will only be legally enforceable if there is a record that the tax has been paid. Anyone might choose not to pay the tax, but if they want to enforce a trade or debt obligation they are on their own. If they want recourse to the courts, rights to exercise on margin/collateral or a valid claim in insolvency, then they pay the tax as their ticket to rely on the legal system.

In the United States we see that the MERS scandal boils down to the wholesale attempt by US banks to avoid paying the transaction taxes on land mortgage registrations with local counties and states. As a result, the very enforceability of millions of mortgages is being thrown into doubt as a matter of law.

Had originators, banks, investment banks and investors been forced to register interests in mortgages in compliance with the law, some of the great abuses of securitisation would have become much more difficult to sustain for so long. In that sense, transparency would have promoted greater accountability and helped curb abuse.

The public has an interest in the integrity of markets. That integrity has been undermined horribly over the past 25 years by demutualisation of exchanges and clearing houses, fragmentation of markets to off-exchange systems and derivatives, leveraged shadow banking, and information assymetries between highly concentrated market insiders and everyone else. We now don't know who owns what and who owes what, and that means that economies are operating with dangerous blind spots. Relaxed accounting rules and forbearance on capital mean that mis-pricing and mis-allocation of capital are endemic and worsening, making any recovery even more doubtful.

A transaction tax on trades, as a pre-condition to legal enforceability, might restore some integrity to markets. That would help restore more efficient functioning to economies with much greater promise than further bailouts to banks.

Testimony of Marriner Eccles to the Committee on the Investigation of Economic Problems in 1933

Below are excerpts from the testimony of Marriner Eccles to the Senate Committee on the Investigation of Economic Problems in 1933. It is an historic document – laying out the future terms of the Federal Deposit Insurance Corporation, the management of money supply nationally through open market operations, the Bretton Woods Accord on currency stability, mortgage refinancing as monetary stimulus, and reforms of the Federal Reserve System to eradicate the excesses of untamed capitalism and financial dominance of Wall Street. He proposes higher income and inheritance taxes as essential to promote economic growth, curb inequality and forestall political instability. He encourages federal regulation of child labor, unemployment insurance, social security and other farsighted reforms. And he avows himself a capitalist throughout.

Although he was a titan of industry - with banks, railroads and corporations spanning the American west - Eccles was born the son of an illiterate, bigamist, Mormon, Scottish immigrant. He was about as far as you could get from the Eastern elite ranks that ran US banking on Wall Street. But he sure understood money, economics and trade, and had the personal drive and charisma to carry his point with the president and with Congress.

Following his testimony, the Utah banker was invited by Franklin Roosevelt to come to Washington to spearhead legislation to enact his proposed reforms. Within two years he had drafted and enacted the Securities Act of 1933 and the Banking Act of 1933(a.k.a., The Glass-Steagall Act, which separated investment and commercial banking and established the FDIC) and the Banking Act of 1935 (which created the modern Board of Governors of the Federal Reserve System and Federal Open Market Committee). He served as Chairman of the Board of Governors of the Federal Reserve System from 1934 until 1951.

Read this and know that just one person, with vision and principles, can make a difference to the world in a time of crisis, establishing the basis for decades of prosperity and growth.

[page 8]

Before effective action can be taken to stop the devastating effects of the depression, it must be recognised that the breakdown of our present economic system is due to the failure of our political and financial leadership to intelligently deal with the money problem. In the real world there is no cause nor reason for the unemployment with its resultant dsestitution and suffering of fully one-third of our entire population. We have all and more of the material wealth which we had at the peak of our prosperity in the year 1929. Our people need and want everything which our abundant facilities and resources are able to provide for them. The problem of production has been solved, and we need no further capital accumulation for the present, which could only be utilised in further increasing our productive facilities or extending further foreign credits. We have a complete economic plant able to supply a superabundance of not only all the necessities of our people, but the comforts and luxuries as well. Our problem, then, becomes one purely of distribution. This can only be brought about by providing purchasing power sufficiently adequate to enable the people to obtain the consumption goods which we, as a nation, are able to produce. The economic system can serve no other purpose and expect to survive.

If our problem is then the result of the failure of our money system to properly function, which today is generally recognised, we then must turn to the consideration of the necessary corrective measures to be brought about in that field; otherwise, we can only expect to sink deeper in our dilemma and distress, with possible revolution, with social disintegration, with the world in ruins, the network of its financial obligations in shreds, with the very basis of law and order shattered. Under such a condition nothing but a primitive society is possible. Difficult and slow would then be the process of rebuilding and it could only then be brought about on a basis of a new political, economic and social system. Why risk such a catastrophe when it can be averted by aggressive measures in the right direction on the part of the Government?

* * *

[page 9]

We could do business on the basis of any dollar value as long as we have a reasonable balance between the value of all goods and services if it were not for the debt structure. The debt structure has obtained its present astronomical proportions due to an unbalanced distribution of wealth production as measured in buying power during our years of prosperity. Too much of the product of labor was diverted into capital goods, and as a result what seemed to be our prosperity was maintained on a basis of abnormal credit both at home and abroad. The time came when we seemed to reach a point of saturation in the credit structure where, generally speaking, additional credi was no longer available, with the result that debtors were forced to curtail their consumption in an effort to create a margin to apply on the reduction of debts. This naturally reduced the demand for goods of all kinds, bringing about what appeared to be overproduction, but what in reality was underconsumption measured in terms of the real world and not the money world. This naturally brought about a falling in prices and unemployment. Unemployment further decreased the consumption of goods, which further increased unemployment, thus bringing about a continuing decline in prices. Earnings began to disappear, requiring economies of all kinds – decreases in wages, salaries, and time of those employed.

[page 10]

The debt structure, in spite of the great amount of liquidation during the past three years, is rapidly becoming unsupportable, with the result that foreclosures, receiverships and bankruptcies are increasing in every field; delinquent taxes are mounting and forcing the closing of schools, thus breaking down our educational system, and moratoriums of all kinds are being resorted to – all this resulting in a steady and gradual breaking down of our entire credit structure, which can only bring additional distress, fear, rebellion, and chaos.

* * *

As an example of Government control and operation of the economic system look to the period of the war, at which time, under Government direction, we were able to produce enough and support not only our entire civilian population on a standard of living far higher than at present, but an immense army of our most productive workers engaged in the business of war, parasites on the economic system, consuming and destroying vast quantities produced by our civilian population; we also provided allies with an endless stream of war materials and consumption goods of all kinds. It seemed as though we were enriched by the waste and destruction of war. Certainly we were not impoverished, because we did not consume and waste except that which we produced. As a matter of fact we consumed and wasted less than we produced as evidenced by the additions to our plant and facilities during the war and the goods which we furnished to our allies. The debt incurred by the Government during the war represents the profit which accrued to certain portions of our population through the operation of our economic system. No Government debt would have been necessary and no great price inflation would have resulted if we had drawn back into the Federal Treasury through taxation all of the profits and savings accumulated during the war.

* * *

[page 11]

How was it that during the period of the prosperity after the war we were able in spite of what is termed our extravagance – which was not extravagance at all; we saved too much and consumed too little – how was it we were able to balance a $4,000,000,000 annual Budget, to pay off ten billion of the Government debt, to make four major reductions in our income tax rates (otherwise all of the Government debt would have been paid), to extend $10,000,000,000 credit to foreign countries represented by our surplus production which we shipped abroad, and add approximately $100,000,000,000 by capital accumulation to our national wealth, represented by plants, equipment, buildings, and construction of all kinds? In the light of this record, is it consistent for our political and financial leadership to demand at this time a balanced Budget by the inauguration of a general sales tax, further reducing the buying power of our people? Is it necessary to conserve Government credit to the point of providing a starvation existence for millions of our people in a land of superabundance? Is the universal demand for Government economy consistent at this time? Is the present lack of confidence due to an unbalanced Budget?

What the public and the business men of this country are interested in is a revival of employment and purchasing power. This would automatically restore confidence and increase profits to a point where the Budget would automatically be balanced in just the same manner as the individual, corporation, State, and city budget would be balanced.

[page 12]

During the past three years there has been such tremendous liquidation and scaling down of debts that extraordinary measures have had to be taken to prevent a general collapse of the credit structure. If such a policy is continued what assurance is there that the influences radiating from a marking down of the claims of creditors will not result in a further decline of prices? In other words, after we have reduced all debts through a basis of scaling down 25 per cent to 50 per cent, what reason have we to expect that prices will not have a further decline by like amount? And then again, the practical difficulties of bringing about such a adjustment on a broad scale seem to be insurmountable.

The time element required would indefinitely prolong the depression; such a policy would necessitate the further liquidation of banks, insurance companies, and all credit institutions, for if the obligations of public bodies, corporations, and individuals were appreciably reduced the assets of such institutions would diminish correspondingly, forcing their liquidation on a large scale. Nothing would so hinder any possibility of recovery. Bank and insurance failures destroy confidence and spread disaster and fear throughout the economic world. The present volume of money would diminish with increased hoarding and decreased credit and velocity, making for further deflation and requiring increased Government support without beneficial results until we would be forced from the gold standard in spite of our 40 per cent of the world’s gold, and, at that point, an undesirable and possibly an uncontrolled inflation with all its attendant evils would likely result, and thus the very action designed to preserve the gold standard and re-establish confidence would destroy both.

[page 13]

We have nearly one and a half billion currency more in circulation at the present time than we had at the peak of 1929, and under our present money system we are able to increase this by several billion more without resorting to any of the three inflationary measures popularly advocated. There is sufficient money available in our present system to adequately adjust our present price structure. Our price structure depends more upon the velocity of money than it does upon its volume.

* * *

In 1929 the high level of prices was supported by a corresponding velocity of credit. The last Federal Reserve Bulletin gives an illuminating picture of this relationship as shown by figures of all member banks. From 1923 to 1925 the turnover of deposits fluctuated from 26 to 32 times per year. From the autumn of 1925 to 1929 the turnover rose to 45 times per year. In 1930, with deposits still increasing, the turnover declined at the year end to 26 times. During the last quarter of 1932 the turnover dropped to 16 times per year. Note that from the high price level of 1929 to the low level of the present this turnover has declined from 45 to 16, or 64 per cent.

[page 14]

I repeat there is plenty of money today to bring about a restoration of prices, but the chief trouble is that it is in the wrong place; it is concentrated in the larger financial centers of the country, the creditor sections, leaving a great portion of the back country, or the debtor sections, drained dry and making it appear that there is a great shortage of money and that it is, therefore, necessary for the Government to print more. This maldistribution of our money supply is the result of the relationship between debtor and creditor sections – just the same as the realtion between this as a creditor nation and another nation as a debtor nation – and the development of our industries into vast systems concentrated in the larger centers. During the period of the depression the creditor sections have acted on our system like a great suction pump, drawing a large portion of the available income and deposits in payment of interest, debts, insurance and dividends as well as in the transfer of balances by the larger corporations normally carried throughout the country.

[page 15]

The maladjustment referred to must be corrected before there can be the necessary velocity of money. I see no way of correcting this situation except through Government action.

[page 21]

Mr Eccles: Of course, the way I look at this matter is that we have the power to produce, just as in the period of prosperity after the war demonstrated when we had a standard of living for a period from 1921 to 1929 which, of course, was far in excess of what it is now. Yet in spite of that standard of living we saved too much a I have previously tried to show.

Senator Gore: You have got Foster in the back of your head?

Mr Eccles: I only wish there were more who had. We saved too much in this regard, that we added too much to our capital equipment. Creating overproduction in one case and underconsumption in the other because of an uneconomic distribution of wealth production. . . . Of course, we are losing $2,000,000,000 per month in unemployment. I can conceive of no greater waste than the waste of reducing our national income about half of what it was. I can not conceive of any waste as great as that. Labor, after all, is our only source of wealth.

[page 22]

There could be no waste in post offices or in roads or in schools. You would have something to show for it. With war all you have left is the expense of taking care of maimed and crippled and sick veterans. That is what is left from war. And it is all wastage.

Senator Gore: You have touched the point. The real cause of the existing trouble was the war, with destruction of over 300 billion dollars of wealth in four years. We are paying the price now. The boys paid the price in blood on the field. We are paying the economic price today. And you may just as well pass a resolution to raise the dead that fell in France as to try to pass laws to avert the inevitable consequences of that war.

Mr Eccles: It is true we are suffering the consequences of the war, but there is no reason why we should be suffering from the consequences of the war if it had not been for the international or the interallied debt that resulted from it. WE are suffering from a debt structure. We are not suffering from the waste, because after all, we know today that we have the power and the facilities to produce certainly all that the people of this country need and want.

* * *

We now see, after nearly four years of depression, that private capital will not go into public works or self-liquidating projects except through government and that if we leave our “rugged individual” to follow his own interest under these conditions he does precisely the wrong thing. Each corporation for its own protection discharges men, reduces pay rolls, curtails its orders for raw materials, postpones construction of new plants and pays off bank loans, adding to the surplus of unusable funds. Every single thing it does to reduce the flow of money makes the situation worse for business as a whole.

[page 24]

I am talking about private credit. If it is credit we need why do not say 200 of our great corporations controlling 40 per cent of our industrial output that are in such shape that they do not need credit – they have great amounts of surplus funds – if it is credit that is needed why do they not put men to work? For the very reason that there is not a demand for goods, that we have destroyed the ability to buy at the source through the operation of our capitalistic system, which has brought about such a maldistribution of wealth production that it has gravitated and gravitated into the hands of – well, comparatively few. Maybe several millions of people. We have still got the unemployment and have got no buying power as a result.

[page 25 – proposal of bank deposit insurance and failed bank resolution]

[page 27 – laying out the basis for what was later to be the FDIC]

However, there is always this danger about that class of thing [Government guarantee of bank deposits]. It encourages bad practices and bad management. It may put a premium on them, which of course we do not want to do, and if it is done there must be rules and regulations for the proper conduct of banks requiring eligibility, and if they fail to meet the eligibility they would be suspended after so much notice, and the fund would be drawn upon to take care of any loss.

[page 31]

Farm mortgages at present are possibly the most undesirable and frozen of all loans, and frozen loans are preventing, to some extent, the necessary expansion of credit. The plan I have proposed [to refinance existing farm mortgages at new lower rates] will very effectively and immediately make liquid billions of dollars of assets for which there is no market today, while at the same time it will bring about a reduction of at least one-third of the average annual payments on the farm debt now required to be made by farm mortgage debtors without requiring any financing or loss by the Federal Government, thus bringing about the necessary relief in the farm mortgage field. This plan has the advantage, as a result of the Government guarantee of the Federal land bank bonds, of diverting surplus funds carried in the great creditor sections into the indirect financing of farm mortgages where it is impossible even at a high rate of interest, which farmers can not pay, to attract those funds directly.

* * *

No program designed to bring this country out of the depression can be considered apart from the relations of this country to the rest of the world unless a policy of complete isolation is adopted and an embargo put on gold exports and our domestic economy adjusted to meet such a condition.

Our international problems are far more difficult and will be slower to work out because of our inability to control the action of other nations. These problems can be met only through international conferences over a period of time. The most important of these problems and the one which must be settled before any progress can be made in the meeting of our domestic or other foreign problems is the problem of interallied debts.

There is a great demand on the part of the public and most of the press of this country that these debts be paid. It seems to me that our political leaders have lacked the courage to face this problem in a realistic manner. This has greatly contributed to prolonging the depression. The public, generally speaking, is not fully informed as to the impossibility of our foreign debtors complying with these demands, which cn only be complied with at the expense of our own people.

[page 32]

It is elementary that debts between nations can ultimately be paid only in goods, gold, or services, or a combination of the three. We already have over 40 per cent of the gold supply of the world – that is not true; it is between 35 and 40 per cent – and as a result most of the former gold standard countries have been forced to leave that standard and currency inflation has been the result. This has greatly reduced the cost of producing foreign goods in terms of our dollar and has made it almost impossible for foreign countries to buy American goods because of the high price of our dollar measured in the depreciated value of their money. This naturally has resulted in debtors trying to meet their obligations by producing and selling more than they buy, thus enabling them to have a favourable balance of trade necessary to meet their obligations to us. If this country is to receive payment of foreign debts, it must buy and consume more than it produces, thus creating a trade balance favourable to our debtors.

* * *

We must choose either between accepting sufficient foreign goods to pay the foreign debts owing to this country, or cancel the debts. This is not a moral problem, but a mathematical one.

[page 33 – the outline of what later became the Bretton Woods Accord]

Cancellation, or a settlement of the debts on a basis which would practically amount to cancellation, in exchange for stabilisation of the currency of the debtors, together with certain trade concessions and an agreement to reduce armaments would be a small price for this country to pay as compared with the great benefits which the entire world, including ourselves, would derive therefrom. Without a stabilisation of foreign currencies it will be difficult, if not impossible, in my opinion, to substantially raise the price level in this country as long as we stay on a gold basis. Our debtors will default and we will likely be forced to abandon gold and depreciate our currency in relation to that of other countries in order to raise our price level in this country and to meet foreign competition unless we are instrumental in inducing foreign countries to stabilise their currencies on a gold basis, or gold and silver basis if action is taken internationally to remonetise silver.

[page 33]

Senator Shortridge: Then I take it you would have the tariffs reduced?

Mr Eccles: No. Debts cancelled. Then I think with the prosperity that you would get in this country you can collect more than that in income and inheritance taxes when you stop this loss of $2,000,000,000 a month through unemployment. You start the process of wealth, and even a capitalist is far better off. I am a capitalist.

* * *

The program which I have proposed is largely of an emergency nature designed to bring rapid economic recovery. However, when recovery is restored, I believe that in order to avoid future disastrous depressions and sustain a balanced prosperity, it will be necessary during the next few years for the Government to assume a greater control and regulation of our entire economic system. There must be a more equitable distribution of wealth production in order to keep purchasing power in a more even balance with production.

If this is to be accomplished there should be a unification of our banking system under the supervision of the Federal Reserve Bank in order to more effectively control our entire money and credit system; a high income and inheritance tax is essential in order to control capital accumulations (this diversion of taxes should be left solely to the central government – the real property and sales tax left to the States); there should be national child labor, minimum wage, unemployment insurance and old age pension laws (such laws left up to the States only create confusion and can not meet the situation nationally unless similar and uniform laws are passed by all States at the same time, which is improbable); all new capital issues offered to the public and all foreign financing should receive the approval of an agency of the Federal Government; this control should also extend to all means of transportation and communication so as to ensure their operation in the public interest. A national planning board, similar to the industries board during the war, is necessary to the proper coordination of public and private activities of the economic world.

Such measures as I have proposed may frighten those of our people who possess wealth. However, they should feel reassured in reflecting upon the following quotation from one of our leading economists:

It is utterly impossible, as this country has demonstrated again and again, for the rich to save as much as they have been trying to save, and save anything that is worth saving. They can save idle factories and useless railroad coaches; they can save empty office buildings and closed banks; they can save paper evidences of foreign loans; but as a class they can not save anything that is worth saving, above and beyond the amount that is made profitable by the increase of consumer buying. It is for the interests of the well to do – to protect them from the results of their own folly – that we should take from them a sufficient amount of their surplus to enable consumers to consume and business to operate at a profit. This is not “soaking the rich”; it is saving the rich. Incidentally, it is the only way to assure them the serenity and security which they do not have at the present moment.

[page 35]
I feel that one of two things is inevitable: That either we have got to take a chance on meeting this unemployment problem and this low-price problem or we are going to get a collapse of our credit structure, which means a collapse of our capitalistic system, and we will then start over. And I therefore would like to see us attempt to regulate and operate our economy which today requires more action from the top due to our entire interdependency than it did in our earlier days.

The quote I have bolded is my favorite part of this testimony, though it is not Eccles' own words. I would be grateful for anyone who can track down a proper citation for the quote. Eccles thought it was either Stuart Chase or William Trufant Foster.

"Deficit Attention Disorder"

I must admit to being delighted that the EU finance ministers have found unity on one point: dismissal of Tim Geithner as officious, ignorant and unaccountable. He is an example, right up there with George W. Bush, of the privileged American elite who "fail upwards" throughout a career.

Europe's nations may have an escalating debt crisis, but they have been addressing it sensibly and cautiously by trying to rein in further debt through reductions in government spending.

The perfect example from the meeting logistics: EU finance ministers shared a bus to the meeting, while Tim Geithner insisted on a private car.

Geithner seems to abhor austerity and sacrifice, preferring any strategy which keeps debt growing to fund the investment banking, security, prisons and war industries on which the American economy now depends for so much of its GDP. (2 percent of Americans are in prison, while 1 percent work for the Department of Defense.)

He encouraged a ten-fold increase in leverage of the EFSF to create a massive new debt overhang. Madness. The cure for a refinancing crisis is not more leverage to be later refinanced.

Europe has its problems, but one thing I know is that the default setting for Europe is cooperation where the default setting for America is conflict. If Tim Geithner's objective in coming to Poland was to stimulate consensus among European finance ministers, then he can go home happy. He succeeded. They are unified in finding him and his policies discredited. They will work together from that consensus to find a more workable solution for Europe than could ever be conceived in Washington, precisely because they will work together in recognition of mutuality of interest.

UPDATE: As this is being linked elsewhere, I'll add a suggestion about what I would advise the eurozone finance ministers. I would advise them to have every EU state with off balance sheet, hidden liabilities on derivatives - whether undertaken for window dressing to gain admission to the eurozone or any other purpose - to default on any further margin or resettlement payments. The Hammersmith and Fulham defaults of the late 1980s proved a wonderful discipline on the investment banks, schooling them in the limits of preying on local governments. It might be time for another lesson at the national level.

Each of the defaulted derivatives contracts could be referred to an EU committee to determine whether the contract had any legitimate rationale beyond disguising the financial condition or otherwise deceiving the public or other EU governments. If there was no legitimate rationale which served the public interest, then the contract would be declared unenforceable.

This wouldn't address decades of deficit spending, but it would provide a popular demonstration of resolve to shaft Wall Street rather than the taxpayer, at least in the first instance. The politicians should then have enough breathing room to reach a more resilient agreement on fiscal policy and funding going forward.

I appreciate that questioning the validity and enforceability of derivatives contracts might be "extra-legal" in the sense that it would be contrary to accepted legal norms. But since virtually every intervention and liquidity programme innovated by a central bank since 2007 has been without legal or statutory basis, despite the huge redistributions of national wealth, I hardly consider that a sticking point.

Liquidity, Bank Capital and Market Reform

A friend forwarded some thoughts on liquidity that are worth sharing here, as liquidity is central to the utility of assets as bank capital and to stabilising markets under stress. My friend's points are in bold, with my commentary below.

Central bankers and securities regulators lost sight of liquidity over the past decade or two in permitting reforms which compromised the health of the financial system. Thanks to the Greenspan and Bernanke puts, and to surplus recycling by Asian economies, many took liquidity - like oxygen - for granted. Like oxygen, you only realise how critical liquidity is when its absence becomes noticeable.

Now that bank regulators have rediscovered liquidity as an essential attribute of healthy banks and healthy markets, it is important to reinforce some key qualities.

Liquidity means you can generate cash from a physical asset or paper claim.

If you can't exchange the asset for a major currency to meet a sudden funding need, then the asset shouldn't be permitted as regulatory capital. Basel II and Basel III have generated hundreds of pages around credit scoring and asset type while ignoring the fact that most of what banks are attributing as capital cannot be turned into cash on demand.

Liquidity can be gained by sale or repo of an asset, preferably in a transparent market. Where no market exists or the market has become illiquid, then liquidity must be gained through a central bank.

Virtually all RMBS markets failed under stress in 2008 and 2009, with failures spreading to other asset classes as investors grew wary of dealer spreads and perceived shallow dealer commitment levels. As the scope of funding problems grew, illiquidity spread to sovereign debt for troubled countries such as Greece and Portugal. Few OTC asset markets have recovered sufficient liquidity for dealing in size.

When the public markets will not price an asset in size without a large spread, then the central banks become the market makers of last resort. Without central bank repo of illiquid RMBS and sovereign debt, virtually every major bank in the OECD would have failed.

Because they now have the role of market maker of last resort, central banks should become much more active in ensuring that any asset permitted to be classed as capital by a bank can be liquidated on demand in a public market. Rather than leaving market structure to the investment banks and their tame securities regulators, the central banks should be driving forward reforms to ensure that capital assets are issued in fungible series, in size, and traded in transparent exchange markets with committed market makers.

This will require a major policy reversal on exchange regulation. Securities regulators have been under pressure for several decades to liberalise OTC markets, permit fragmentation to off-exchange trading systems, and turn a blind eye to issuance of securities in small, idiosyncratic offerings that will never liquidly trade except back through the offering investment banks. The quality assurance and market conduct functions of exchanges have been eroded following demutualisation, and exchanges now are run for profit of their highly concentrated owners rather than in the public interest.

Markets are at the heart of successful civilisations. Markets require quality norms, information publication, and price transparency to operate effectively. Regulators and investors allowed credit ratings to substitute for exchange listing rules and reporting requirements during the liquidity boom. Ratings were gamed by the banks until they were meaningless. We should now be forcing assets back onto exchanges and force the exchanges to regulate quality and information norms in the public interest. If this requires re-mutualising the exchanges, or public ownership of exchanges, then that should be on the agenda. Letting the exchanges be run by the thugs who gamed the markets and the rating agencies isn't healthy.

Liquidity means that proceeds of sale will be paid as funds to your account in a currency you can use widely to meet obligations.

If you can only sell your asset into a market denominated in a currency which itself is not liquid and not legal tender for meeting your obligations, then you haven't got liquidity vested in the asset. A lot of investors in emerging markets are probably going to find that liquidity in those markets is a lot less than they might think, despite advances in exchange trading of emerging market assets, and the currencies might be less liquid too in a falling market. If they require funding in their home currency, they risk taking a big hit on sale and FX spreads when they realise the asset under stress.

Liquidity is measured by size, speed and spread - not by price levels.

Whatever the market price, a market isn't liquid if those holding assets in size cannot deal in size. A market is not liquid if those holding assets cannot sell at the time the sell decision is made, but must wait to identify or attract sufficient buyers. A market is not liquid if the spread between the bid and ask is so wide that buyers will be deterred from the market by the risk of never recovering the spread in appreciation or returns. The way that markets have levitated on minimal volumes in 2010 and 2011 is no indication that the markets are liquid. As we've seen in August, even mild selling can have a massive effect on prices in an illiquid market.

Short sales are an attribute of liquid markets. If a market can't be shorted, then the market will fail as prices fall.

Short sellers will come in to buy assets in a falling market to realise a profit. They provide liquidity when everyone else is too scared to deal.

Securities markets regulators and central bankers need to think through liquidity as an attribute of market structure in the public interest. Idiosyncratic, illiquid, ill-transparent deals and instruments which have dominated market growth for the past two decades are behind the weakness of bank capital and market recovery. The regulatory incentives should be toward standardisation of securities terms and offering documents, much larger issues of securities and series of bonds, and fungibility of asset types within a class. Exchange trading should be encouraged, fragmentation discouraged. Exchanges should provide rigorous listing rules, timely reporting of market relevant information, full price transparency and two-way quote obligations on market makers. If we got that right, then much of the misrepresentation, mispricing, inefficiency and fraud of the past would become impossible in future.
