Financing the Green Economy Transition


Below is a short paper I wrote as part of work with Sir David King and the Smith School of Enterprise and the Environment:

“We are capable of shutting off the sun and the stars because they do not pay a dividend. London is one of the richest cities in the history of civilization, but it cannot “afford” the highest standards of achievement of which its own living citizens are capable, because they do not “pay.”

If I had the power to-day, I should most deliberately set out to endow our capital cities with all the appurtenances of art and civilization on the highest standards of which the citizens of each were individually capable, convinced that what I could create, I could afford….

John Maynard Keynes. “National Self-Sufficiency,” The Yale Review, Vol. 22, no. 4 (June 1933), pp. 755-769.

UNEP’s latest publication, Towards a Green Economy tackles the vexed question of financing the Green Transition and estimates that

 

“to halve CO2  emissions by 2050, requires investments of approximately US$ 750 billion per year from 2010 to 2030 and US$1.6 trillion per year from 2030 to 2050. The World Economic Forum and Bloomberg New Energy Finance, on the other hand, calculate that clean energy investment needs to rise to US$ 500 billion per year by 2020 to restrict global warming to less than 2ºC, while HSBC estimates that transition to a low-carbon energy market will require US$ 10 trillion between 2010 and 2020.” (Towards a Green Economy, page 33.)

The Green Economy team at UNEP make their assessment based on achievement both of the above carbon emissions target, but also the Millennium Development Goals, and estimate a range of US$1.05 trillion to US$2.59 trillion annually.

“On average, these additional investments amounted to 2% of global GDP per year over 2010-2050, across a range of sectors to build capacity, adopt new technologies and management techniques, and scale up green infrastructure.”

The report then proposes a range of potential ways of financing these investments. The UNEP team look to “institutional investors such as pension funds and insurance companies”; to “public financing” by which no doubt is meant taxation and government borrowing from capital markets; to global development institutions (e.g. the IMF, World Bank and other multilateral institutions); and finally to “stable and resilient capital markets.”

In this short paper I want to argue that the financing of a ‘Green Transition’ is affordable, and need not be drawn down from what can broadly be defined as ‘savings’: namely the share of income not consumed by individuals, households, firms, governments and global institutions, and instead ‘saved’ as taxation, capital, pension funds, and reserves.

Instead the financing of a Green Transition should be undertaken in much the same way as e.g. the financing of the Industrial Revolution, the Second World War, and the recent 2007-9 Bank Bailout: by the banking system’s creation of credit at low, sustainable rates of interest. This financing must then be used for investment in productive activity that substantially lowers emissions, facilitates the transition to a de-carbonised economy, and generates the income to repay the public and private banking system’s loans.

The annual sums required for the Green Transition are not excessive, when compared, for example to the intervention undertaken to support the banks in the UK, US and euro-area during the financial crisis. According to the Bank of England’s 2008-9 Financial Stability Report (June 2009, Issue No. 25)

“overall, the total value of actual and contingent support in North America and Europe rose to over US$14 trillion, equivalent to about 50% of annual GDP.”

UNEP’s requirement of 2% of GDP  for financing the Green Transition is modest by comparison to the financing made available by central banks to the private banking sector, and indirectly to governments (through the purchases of bonds/gilts) in 2009.

Savings not needed to finance the Green Transition

In this short note I want to re-state facts known to economists down the ages, but most clearly explained by Keynes, and then subsequently lost to the field of macroeconomics.

The nature of money is highly peculiar. It is very different from the point of view of an individual and from the point of view of the system as a whole. Individuals cannot magic money from nothing. But the banking system as a whole can magic money from nothing.

This money can be used to bring economic activity into existence. Credit creates savings/deposits. Economic activity generates saving, it is not constrained by saving.

Keynes’s predecessors, the Classical economists saw things differently.  According to Classical theory, saving was necessary prior to investment. Money – deposits or savings – existed only as the result of economic activity. These savings (or vaults of silver/gold) then created economic activity.

Keynes’s great contribution was to demonstrate the contrary: that saving, which is another word for non-consumption, or delayed consumption, is not necessary prior to investment. In other words, if a bank promises credit for an investment it really disposes of something belonging to the future: the coming saving. Credit creates deposits and savings. Credit creates economic activity.

Victorian constraints on finance

The economic theory that saving was necessary prior to investment came about, in part, because banks at that time were not adequate to the demands of rapid industrialisation, and firms could not easily raise funds for large-scale investment. Instead they relied on the savings of individuals. The saving habits of the time were therefore incorporated into Classical or Victorian economics and persist to this day in neo-classical economic theory – still dominant in our universities and think-tanks.

For the Victorians, banks were merely channels, passing money from lenders to borrowers; from individuals to firms and governments.[i] But as the banking system evolved, banks were able to create credit in excess of savings.  With time it became clear that neither savings, nor prudent savers were necessary or essential for investment.  Once society accepted banking systems and bank money, money was no longer a scarce resource.  Economic activity was, and is, no longer bound up with, and dependent on the few with savings in excess of income.

Investment was, and is no longer constrained by saving.

Today, to make loans, banks (both central banks and private banks) do not have “savings” or “deposits” – either theirs, or those of others – to extend to others as credit, and on which they charge interest.  The money for a bank loan does not exist, until the borrowers apply for credit. (The myth of ‘fractional reserve banking’ is just that: a myth.) Central banks do not need to tax the population, or to mobilise savings, before the creation of what is today known as ‘Quantitative Easing’, but was in the past known as ‘Money Market Operations’ etc.  

At the height of the financial crisis, Governor Ben Bernanke was asked where he had found $160 billion to bail out an insurance company, AIG. Had he raised the funds from taxation? No, he replied:

“It’s not tax money. The banks have accounts with the Fed, much the same way that you have an account in a commercial bank.”

“So, to lend to a bank, we simply use the computer to mark up the size of the account that they have with the Fed.” (CBS 60 Minutes Show 15 March 2009).

In today’s economy, there is no tangible quantity corresponding to the aggregate of bank money in an economy at any point in time. Such a tangible quantity/quality is not a necessary characteristic of money. The acceptability and hence validity of bank money is due to its being able to facilitate transactions. [ii] To enable society, in Keynes’s terms, to ‘afford that which we can create’.

For investors that operate in today’s monetary economies, the relevant consideration is the availability of finance, not savings, and there need be no constraint on finance – because credit is not a commodity and there need be no limit to its creation.

This makes credit both a powerful resource for human development and protection of the ecosystem; but also a dangerous power if unchecked and governed by ‘light-touch regulation’.  If more credit is created by the banking system than there is potential for economic activity, then the outcome is inflation. If less credit is created than there is potential for economic activity, then the outcome is deflation. Furthermore, if loans are made at rates of interest above a sustainable rate of return, the loans become unpayable.

Supply and the price of money

Fortunately, bank money has a second great advantage, the very thing that had motivated its invention: lower interest rates. Public banks could increase the supply of money, and thereby lower its price: the rate of interest. Entrepreneurs were no longer ‘in hock’ to those with savings in excess of income, who were often usurers.

For unlike gold or oil, credit is not subject to the laws of supply and demand. And because it is not subject to the laws of supply and demand, its price – or the rate of interest – should always be low, and is necessarily a social construct. In other words, the price of credit is influenced not by shortages or gluts, but above all by committees of men and women, based in central banks, and in the private banking system, who determine the most appropriate rates of interest for the economy, or for the private banking sector. (Consideration is not, so far, given to the ecological sustainability of rates.) The 2009 creation of extraordinary levels of ‘support’ – $16 trillion – for the banking system was accompanied by decisions by central bank committees to push base or policy rates to the lowest levels in history. While rates across the spectrum did fall, central banks have unfortunately lost control over rates set by the private sector, now determined overwhelmingly by the British Bankers Association’s determination of the London Interbank Offer Rate (LIBOR).

Bank money was a remarkable and very welcome development; a great public good. Indeed capitalism owes much of its advance to the development of sound banking systems.

Using the banking system to facilitate the Green Transition

By increasing the amount of credit in circulation, bank money facilitated what we have come to regard as progress.  The development of modern technology (the light bulb and the steam engine) would not have taken place if entrepreneurs had not had their research and development funded by low-cost finance made available by bank money. Trade was made possible with bank money. The welfare state was made possible by bank money.  And financial crises have been ameliorated by the issuance of bank money.

The 2009 financial crisis demonstrated to the public that the relevant consideration is the availability of finance, in the form of Quantitative Easing, not savings, and there need be no constraint on finance. Society now needs to argue that just as there was no constraint on the financing of the 2009 bailout, so there need be no constraint on the financing of the Green Transition. Instead there must be careful regulation of that financing, and of the rate of interest attached to loans for investment in the de-carbonisation of the economy.

The financing and investment of 2% of global GDP in the Green Transition will in turn generate economic activity, and with it the deposits and savings needed to repay lending. There will be no need to resort to taxation, pension funds or other sources of ‘saving’. Indeed sound economic activity will generate additional savings for individuals, firms and governments.


[i] The US’s Treasury Secretary Tim Geithner believes that banks are merely channels. In testimony to Congress in September, 2009 he said: “Stripped of its complexities, the purpose of a financial system is to let those who want to save -whether for vacation, retirement or a rainy day –save. It is to let those who want to borrow -whether to buy a house or build a business –borrow. And it is to use our banks and other financial institutions to bring saversfunds and borrowers’ needs together and carefully manage the risks involved in transfers between them.”   Financial Services Committee, Congress, 23 September, 2009.

    I disagree mainly on one point, namely the low interest rate you propose.

    I, and I think you assume the Bank of England creates this money/credit. It must be paid back in the future or else inflation results.

    It must therefore be lent on projects that have a very low chance of failure to produce. It must not be lent on assets such as land because that simply bids up their asset value. In this sense assets behave like bonds: high interest means low price / low interest means high price. There is therefore a danger that low interest rates can feed through and create asset bubbles.

    When Keynes was taken to task for the low interest rates he proposed he pointed out that in the 1920s there was deflation. Therefore those who were forced to draw on their savings because they could no longer live on the interest on their savings had the benefit that the purchasing power of their savings was increasing. That is not so today! Those with savings are suffering high inflation and very low interest rates on their savings.

    The right approach is for the BoE to create money in a new Green Bank to lend out at say 6%. The BoE must also create nearly all (e.g. 4.5%) of this interest and spend it into circulation, for example as grants to pay for development trials, etc. This 4.5% is not inflationary because it flows back to the BoE making the net interest rate 1.5%.

    That might sound complicated. But it enables the maintenance of a Base Rate of 5% so that those trying to live on savings in the face of inflation can do so.

    It is my view that interest rates should be held stable, not reduced to nearly nothing as now. Money and asset values should instead be stabilised by the amount of credit / money the BoE and banks create. Indeed the average credit in the system ought to be kept constant. It is now falling as householders and businesses scramble to pay off their ‘debts’. Credit could be created by means of a Green Bank subsidiary of the BoE and this could help restore the amount of credit in the system to normal.

    Low interest rates do not mean that you can easily borrow. Banks ration the credit they create. They do not like backing new projects or wiz kids. They can vanish to S America. They much prefer to secure their loans on something than can’t vanish such as land. They all do / did it. They all competed with offers of higher and higher loans up to over 100% the value of real estate. Result: Asset bubble. That is why normal interest rates should be kept ‘normal’. The interest charged by a Green Bank can also be normal, but subsidised by it spending much of what it gets back in interest as grants in the green economy. That keeps the low cost money in the Green Economy.

  • […] to fund the transition to a green economy, according to Ann […]

  • “And financial crises have been ameliorated by the issuance of bank money.”

    Technically, yes, but surely the Financial Crisis (which Canada did not experience, by the way, because of their hippy regulations) taught us there’s not enough regulations on loans given out. That’s obvious.

    The original problem was that as Banks obviously have a vested interest in giving out loans, they did so, excessively to clients with no earning potential. This is where a legislator or two could have stepped in about 20 years ago and put some kind of limit on who can take out loans.

  • Ann

    Absolutely Michael. Both legislators and regulators…regulators mandated by legislators. As Prof. Chick has noted, there is very little debate in economic circles about who or what organisation/institution determines, or should determine the money supply. While central banks will issue QE periodically, they then wash their hands of the money supply, leaving it up to speculators/gamblers and reckless bankers in the private sector….. free to issue as much as they like…regardless of risk.
