2.1. Banks promote profits by credit financing and central banks keep credit costs low to ensure financial stability
At the beginning of capitalism, companies increasingly used machines to produce goods. Their use generates enormous growth in the economy and leads to considerable prosperity in Western industrialized nations. With increasing credit financing of the capital used, banks and central banks now become the main players in economic development.
The modern capitalist credit economy is characterized by close cooperation between companies and banks. Credit financing is its link. It allows entrepreneurs to significantly increase their return in capital through debt financing. Increasing debt financing raises business risks and makes the economy unstable. The instability has come to light with the financial crisis. With this crisis, central banks now feel obliged to use all their means to ensure the stability of the financial system
As we face a new era, it is imperative to understand how the new central bank policy works for credit in the capitalist economy. In this regard, we are interested in the impact of its expansionary liquidity at reduced cost and risk. To do this, let’s first look at the situation faced by an entrepreneur who wants to secure its future earnings and profits through today’s investments.
Investment decisions are based on important research and development work. At that level different specialists such as biologists, chemists, physicists, engineers, IT specialists and designers drive technical progress. It manifests itself in innovation, such as new products, novel services and concepts, and new production processes. This level creates the basis for lucrative sales opportunities and worthwhile project returns rp.
The entrepreneur will decide to invest if his project return r
p is greater than the market interest rate i. If r
p > i, then his investment project looks profitable in the future. Otherwise, it would be better if he gives his money to a bank earning interest. If the investment project is expected to generate profits, then it is also of interest to the bank.
It can participate in the promising project by supporting it with credit. On the one hand, credit financing is associated with additional costs, but on the other hand, it can significantly increase profitability. The bank charges the market interest rate i plus a risk premium p
r for the loan. The loan reinforces the profitability r
e of the entrepreneur’s invested money via a
leverage v according to the formula
as long as the project return r
p is greater than the finance cost i + p
r. Otherwise in bad times with increasing financial costs, the
return on equity r
e will be reduced and can even be negative. Then the firm may lack the necessary liquidity and it must use part of its equity to pay its finance cost and runs the risk of insolvency. The leverage v is the ratio of debt capital to equity.
The new central bank policy with financial stability aims to lower the market interest rate i and the risk premium pr.
The expected rate of return r
p varies from project to project. Statistically, we have a distribution of returns as schematically illustrated in
Figure 1 “Distribution of project returns in normal times”.
We start the schematic representation of the distribution of project returns h(r
p) with a symmetric diagram for normal economic times. The symmetry places the maximum h
mn of the distribution h(r
p) in its center. The financial costs i + p
r represent a lower limit, a break-even point. All projects with a return r
p greater than the threshold i + p
r should be considered worthwhile to receive recognition and for banks to support them through loan financing. The scope of worthwhile projects is shown shaded in
Figure 1 “Distribution of project returns in normal times”. As the break-even point i + p
r is approached, the risk of insolvency increases.
In the transition from normal to good times, sales opportunities and financial conditions improve for entrepreneurs. Increased demand leads to higher project returns r
p for many more companies. The result in
Figure 2 “Distribution of project returns in good times” is that the maximum h
mg of the distribution h(r
p) slides further to the right into the area of higher returns r
p. Lower financing costs make projects of additional firms with low returns profitable, the threshold i + p
r is moving to i
g + p
rg in the left of the area of low returns r
p. As in
Figure 1,
Figure 2 shows the amount of profitable projects shaded. Due to better economic conditions it has increased significantly compared to
Figure 1. Moreover, as banks lend now more easily, the leverage v rises and so does the return on equity r
e and, finally, the company’s profits П.
In bad times, the economic situation reverses. Sales opportunities shrink and financing costs rise. Under these conditions banks are more cautious in granting loans, the leverage v decreases.
The new situation is shown in
Figure 3 “Distribution of project returns in bad times”. The drop in demand shifts the maximum h
mb of the returns distribution h(r
p) to the left. Fewer projects are now profitable. The increased financing costs make the critical financial threshold shift to the right, from i
g + p
rg good times to i
b + p
rb bad times. They further reduce the number of profitable projects. Many companies now run into difficulties. Graphically, this becomes clear in
Figure 3 by the fact that the shaded area, showing the profitable companies, decreases significantly.
Now central banks have to step in and ensure stability. To do this, they have to intervene heavily in the financial market to restore conditions as in normal or good times. Central banks measures have
a less significant impact on sales than on financing costs. They could move the threshold i
b + p
rb toward i
g + p
rg as indicated by the bold arrow in
Figure 3, but not noticeably change the distribution of returns h(r
p). With the impact of financial costs a lot of firms with low returns can stay in the market that would otherwise go bankrupt. Under the bad market conditions, central banks keep many companies with low returns from insolvency and thus they favor evergreening. These firms can continue to borrow and increase their profits through the leverage v. But it is not only firms with low profitability that benefit. The new central bank policy provides additional profits П to all firms with profitability above the critical threshold.
2.2. Long-term instability on the rise
Two effects of central bank’s policy are apparent. Overall, profits П increase and firms with low profitability can remain in the market or join it. The second effect favors evergreening and weakens the market forces in economic development as described by Schumpeter (1883 -1950). On top of this, banks are likely to be more willing to lend because of the central bank’s takeover of risk, thus expanding debt financing. This puts the balance between credit and growth in jeopardy, as growth falls behind.
In debt financing, Minsky (1919 – 1996) has seen the cause of economic instability. He distinguishes three types of finance:
Hedge finance
Speculative finance
Ponzi finance
With hedge finance, current revenues are sufficient to meet all payment obligations of the considered firm over a longer period of time. Current interest is paid including risk premium, and outstanding debts are repaid. In the case of speculative and Ponzi finance, current earnings are not sufficient to meet all financial payment obligations. In the case of speculative finance, the interest and the risk premium are repaid and the old debts that are repaid are replaced by taking on new debts, without increasing the indebtedness. In the case of Ponzi finance, the current finance costs are settled and the debt level is increasing. With the rise of debt the follow-up costs of credit financing increase and financial costs and risk are postponed into the future. Both debtors and creditors are now highly dependent on the development of the financial market.
One can argue that debt expansion à la Ponzi is economically viable as long as profitability is greater than financial costs, as long as rp is greater than i + pr. However, the volatility shows that this situation is highly risky and can easily lead to an economic crisis. In the long term, therefore, the CB new policy based on increasing credits cannot form a stable foundation for economic development as long as sales opportunities lag behind.
The new central bank policy is aimed at increasing companies’ profits П and reducing their market and financial risks. This policy also favors government spending. By buying up bad government loans, the central bank frees the state from old burdens, and the low interest rates allow the state to borrow cheaply to finance its current expenditures. Thus, the central bank supports the monetary financing of government activity and the expansion of government debt. Fiscal policy thus becomes dependent on central bank policy.
2.3. Inequality on the rise
Companies and governments benefit from high liquidity at low cost. This statement does not apply to all private households. The low interest rates are hardly an incentive to save money for the poor. They are increasingly dependent on help. Their dependence on it is increasing. The situation is quite different for richer people with income from profits. The result is a divided society with increased inequality.
As explained, the new central bank policy focuses on increasing the return on equity re and thus profits П. This is how it intends to stabilize the economy. By far the largest share of profits goes to the richer households. They consume much less of it than poorer households do from their income. The savings rate sП of the richer households is close to one, whereas the consumption rate cw of the poorer households is close to one, see Pauly, (2021, 4.2 Inequality of income and wealth, p. 144-149).
With the policy of low interest rates, the central bank reduces the incentive among the poorer to save and provide for their future. Their propensity sw to save is falling. As the propensity to save falls among the poorer and the profits of the richer rise, inequality in society grows. In addition, the richer can venture more. Much risk in investment decisions has been taken away by the central bank.
In Keynes’ day money, especially from households, was still flowing into real investment projects, at that time the main function of the financial system was the transformation of household’s savings into productive investment. Today much of banks’ money, outside and inside money, is directed into profitable financial projects. If real investments are productive for economic growth, most financial investments are unproductive, for example, a lot of money that is going into the real estate market has no effect on growth. Real investments I increase the national capital stock K and thus the national growth rate g. Investments as a whole increase wealth Σ and will further increase inequality. This has been pointed out by Piketty (2013) in his well-known inequality r > g, the return of wealth r is greater than the growth rate g.
Let us reformulate Piketty’s inequality by distinguishing more clearly between productive capital K and wealth Σ. By including the price p
Σ of the stock of wealth Σ and noting that savings from profits П substantially determine the increase in wealth, the increase in wealth is
And after transforming this results in the growth rate g
∑ = ΔΣ/Σ
Central bank policy, with its cheap liquidity policy, pushes the rate of inflation of stocks in the economy, significantly increasing p∑, prices especially in the real estate and art markets, but also in the stock market. Central bank policy makes, as we know, profits П in (2) swell and thus the rate of return of wealth r in (3). As there is a tendency for the growth rate g to decrease via evergreening, g will clearly lag behind the growth rate of wealth gΣ, gΣ > g. Inequality continues to grow.
2.4. Loss of confidence: Credit expansion - the source of imbalance in the economic development
And now more about loans. Mankind for centuries has been amazed to find that with orientation of the future in their present life, it actually makes the future a better place to live. This forward orientation has been successful for centuries and the success is based on credit and exploitation of nature. The credit system finances a promising future with the obligation to pay the finance costs tomorrow, especially via the Ponzi finance system. The economy has a tendency to postpone the follow-up costs, such as financial costs and costs of environmental exploitation, into the future.
We can look back on a long glorious history of credits. In former times, farmers could observe that working the soil today with better tools produces additional yield in the next period. An increased use of technical products that farmers bought from craftsmen made it necessary for them to finance their purchases with external funds. They are taking on debt today. And it pays off for them, as long as their tomorrow’s return will exceed the financial costs they incurred yesterday. Later in the industrial revolution, entrepreneurs have taken advantage of credit financing and bought machinery and factories financed with credit.
With our orientation towards the future, we become slaves to our expectations that we will be better off tomorrow than we are today. In order for these expectations to be realized, we need growth tomorrow with which we can pay our credit obligations that we have made today. Banks together with central banks and political actors are expanding the volume of credit in the economy, which requires further growth. However, when the growth will not be high enough to finance the credit costs, the equilibrium of the evolutionary economy based on high credit and high growth would be endangered.
We can now state the proposition that people become slaves to their expected growth increasingly based on credits. This attitude is typical in the modern capitalist credit economy. More pointedly we can say that the overstretched credit-financed capitalist economy makes the state and society slaves to growth. This is how the state-supported capitalist credit economy comes into being.
Innovative entrepreneurs are the main actors in the modern process of credit based economic evolution. They are supported by commercial banks. They provide the loans that entrepreneurs need to finance and market the production of their new goods. Following Schumpeter one can say that credit creation is the complement of innovation.
More generally, today entrepreneurs finance their production with loans and tomorrow they sell their produced goods at a profit after paying their financial costs. This is the economically fruitful intertemporal exchange that has sustained economic development for centuries and in which economic agents have confidence. This trust is based on a lot of credit and a lot of growth. According to Harari (2011), trust, credit and growth are the pillars of the modern economy. This long-lasting stable balance between much credit and high growth is becoming unstable and trust is dwindling.
We can regard growth g as beneficial to investment on projects as it increases sales opportunities, in
Figure 1-3 the sales opportunities are reflected in the distributions of project returns r
p and have a great impact on the economic development. Thus, growth g can be seen as closely linked to project returns on r
p. Some economists view future growth opportunities as low, for example R. J. Gordon (2016). Others consider the future full of opportunities, for example J. Mokyr. According to Gordon, the era of high growth is over. J. Mokyr sees it differently: “Mokyr, on the other hand, sees a bright future for economic growth, spurred by nations competing to be the leader in science and technology, and the resulting rapid spread of innovation worldwide. He sees the potential for progress in laser technology, medical science, genetic engineering and 3D printing”, here quoted from Banerjee and Duflo (2019), p. 151.
The future is open and also the answer to the growth question. What can be said, however, is that central banks favor evergreening and thus impede economic growth as Schumpeter saw it with innovative companies.
Furthermore, the transformation of production, as required by the climate crisis, will first make it more difficult for an economy to grow as it will increase the costs and will further stimulate credit expansion. The splitting of the global economy into a few large economic areas of strategic partnerships is also to lead to higher costs.
Credit can be a blessing for mankind, but it can also be a danger. As Minsky argues, debt financing is a source of economic instability. In crises, sales threaten to collapse, growth g is slowing down, and thus the project profitability p
r can fall below the financial costs i + p
r , companies have to fall back on their equity capital and the insolvency spiral can begin, as we know from formula (1) and
Figure 1-3.
