If governments sought funding from the central bank for their net spending (deficits) rather than private bond markets then the inflation risk of such spending would remain unchanged.
Answer: True
The answer is True.
The mainstream macroeconomic textbooks all have a chapter on fiscal policy (and it is often written in the context of the so-called IS-LM model but not always).
The chapters always introduces the so-called Government Budget Constraint (as explained above) that alleges that governments have to "finance" all spending either through taxation; debt-issuance; or money creation. The writer fails to understand that government spending is performed in the same way irrespective of the accompanying monetary operations.
They claim that money creation (borrowing from central bank) is inflationary while the latter (private bond sales) is less so. These conclusions are based on their erroneous claim that "money creation" adds more to aggregate demand than bond sales, because the latter forces up interest rates which crowd out some private spending.
All these claims are without foundation in a fiat monetary system and an understanding of the banking operations that occur when governments spend and issue debt helps to show why.
So what would happen if a sovereign, currency-issuing government (with a flexible exchange rate) ran a budget deficit without issuing debt?
Like all government spending, the Treasury would credit the reserve accounts held by the commercial bank at the central bank. The commercial bank in question would be where the target of the spending had an account. So the commercial bank's assets rise and its liabilities also increase because a deposit would be made.
The transactions are clear: The commercial bank's assets rise and its liabilities also increase because a new deposit has been made. Further, the target of the fiscal initiative enjoys increased assets (bank deposit) and net worth (a liability/equity entry on their balance sheet).
Taxation does the opposite and so a deficit (spending greater than taxation) means that reserves increase and private net worth increases.
This means that there are likely to be excess reserves in the "cash system" which then raises issues for the central bank about its liquidity management. The aim of the central bank is to "hit" a target interest rate and so it has to ensure that competitive forces in the interbank market do not compromise that target.
When there are excess reserves there is downward pressure on the overnight interest rate (as banks scurry to seek interest-earning opportunities), the central bank then has to sell government bonds to the banks to soak the excess up and maintain liquidity at a level consistent with the target. Some central banks offer a return on overnight reserves which reduces the need to sell debt as a liquidity management operation.
There is no sense that these debt sales have anything to do with "financing" government net spending. The sales are a monetary operation aimed at interest-rate maintenance. So M1 (deposits in the non-government sector) rise as a result of the deficit without a corresponding increase in liabilities. It is this result that leads to the conclusion that that deficits increase net financial assets in the non-government sector.
What would happen if there were bond sales? All that happens is that the banks reserves are reduced by the bond sales but this does not reduce the deposits created by the net spending. So net worth is not altered. What is changed is the composition of the asset portfolio held in the non-government sector.
The only difference between the Treasury "borrowing from the central bank" and issuing debt to the private sector is that the central bank has to use different operations to pursue its policy interest rate target. If it debt is not issued to match the deficit then it has to either pay interest on excess reserves (which most central banks are doing now anyway) or let the target rate fall to zero (the Japan solution).
There is no difference to the impact of the deficits on net worth in the non-government sector.
Mainstream economists would say that by draining the reserves, the central bank has reduced the ability of banks to lend which then, via the money multiplier, expands the money supply.
However, the reality is that:
So the banks are able to create as much credit as they can find credit-worthy customers to hold irrespective of the operations that accompany government net spending.
This doesn't lead to the conclusion that deficits do not carry an inflation risk. All components of aggregate demand carry an inflation risk if they become excessive, which can only be defined in terms of the relation between spending and productive capacity.
It is totally fallacious to think that private placement of debt reduces the inflation risk. It does not.

Premium question 5:
Modern Monetary Theory (MMT) considers that the public debt ratio is of no concern because economic growth will always bring it down after a recession.
The answer is False.
First, the public debt ratio is of no concern per se if the nation is sovereign in its own currency. But the question was probing whether you understand the dynamics of the ratio in relation to GDP growth.
The primary deficit may not fall when economic growth is positive if discretionary policy changes offset the declining net spending as tax revenue increases and welfare payments fall (the automatic stabilisation).
Under current institutional arrangements, governments around the world voluntarily issue debt into the private bond markets to match $-for-$ their net spending flows in each period. A sovereign government within a fiat currency system does not have to issue any debt and could run continuous budget deficits (that is, forever) with a zero public debt.
The reason they is covered in the following blogs - On voluntary constraints that undermine public purpose.
The framework for considering this question is provided by the accounting relationship linking the budget flows (spending, taxation and interest servicing) with relevant stocks (base money and government bonds).
This framework has been interpreted by the mainstream macroeconommists as constituting an a priori financial constraint on government spending (more on this soon) and by proponents of Modern Monetary Theory (MMT) as an ex post accounting relationship that has to be true in a stock-flow consistent macro model but which carries no particular import other than to measure the changes in stocks between periods. These changes are also not particularly significant within MMT given that a sovereign government is never revenue constrained because it is the monopoly issuer of the currency.
To understand the difference in viewpoint we might usefully start with the mainstream view. The way the mainstream macroeconomics textbooks build this narrative is to draw an analogy between the household and the sovereign government and to assert that the microeconomic constraints that are imposed on individual or household choices apply equally without qualification to the government. The framework for analysing these choices has been called the government budget constraint (GBC) in the literature.
The GBC is in fact an accounting statement relating government spending and taxation to stocks of debt and high powered money. However, the accounting character is downplayed and instead it is presented by mainstream economists as an a priori financial constraint that has to be obeyed. So immediately they shift, without explanation, from an ex post sum that has to be true because it is an accounting identity, to an alleged behavioural constraint on government action.
The GBC is always true ex post but never represents an a priori financial constraint for a sovereign government running a flexible-exchange rate non-convertible currency. That is, the parity between its currency and other currencies floats and the the government does not guarantee to convert the unit of account (the currency) into anything else of value (like gold or silver).
This literature emerged in the 1960s during a period when the neo-classical microeconomists were trying to gain control of the macroeconomic policy agenda by undermining the theoretical validity of the, then, dominant Keynesian macroeconomics. There was nothing particularly progressive about the macroeconomics of the day which is known as Keynesian although as I explain in this blog - Those bad Keynesians are to blame - that is a bit of a misnomer.
Anyway, just as an individual or a household is conceived in orthodox microeconomic theory to maximise utility (real income) subject to their budget constraints, this emerging approach also constructed the government as being constrained by a budget or "financing" constraint. Accordingly, they developed an analytical framework whereby the budget deficits had stock implications - this is the so-called GBC.
So within this model, taxes are conceived as providing the funds to the government to allow it to spend. Further, this approach asserts that any excess in government spending over taxation receipts then has to be "financed" in two ways: (a) by borrowing from the public; and (b) by printing money.
You can see that the approach is a gold standard approach where the quantity of "money" in circulation is proportional (via a fixed exchange price) to the stock of gold that a nation holds at any point in time. So if the government wants to spend more it has to take money off the non-government sector either via taxation of bond-issuance.
However, in a fiat currency system, the mainstream analogy between the household and the government is flawed at the most elemental level. The household must work out the financing before it can spend. The household cannot spend first. The government can spend first and ultimately does not have to worry about financing such expenditure.
From a policy perspective, they believed (via the flawed Quantity Theory of Money) that "printing money" would be inflationary (even though governments do not spend by printing money anyway. So they recommended that deficits be covered by debt-issuance, which they then claimed would increase interest rates by increasing demand for scarce savings and crowd out private investment. All sorts of variations on this nonsense has appeared ranging from the moderate Keynesians (and some Post Keynesians) who claim the "financial crowding out" (via interest rate increases) is moderate to the extreme conservatives who say it is 100 per cent (that is, no output increase accompanies government spending).
So the GBC is the mainstream macroeconomics framework for analysing these "financing" choices and it says that the budget deficit in year t is equal to the change in government debt (ΔB) over year t plus the change in high powered money (ΔH) over year t. If we think of this in real terms (rather than monetary terms), the mathematical expression of this is written as:
which you can read in English as saying that Budget deficit (BD) = Government spending (G) - Tax receipts (T) + Government interest payments (rBt-1), all in real terms.
However, this is merely an accounting statement. It has to be true if things have been added and subtracted properly in accounting for the dealings between the government and non-government sectors.
In mainstream economics, money creation is erroneously depicted as the government asking the central bank to buy treasury bonds which the central bank in return then prints money. The government then spends this money. This is called debt monetisation and we have shown in the Deficits 101 series how this conception is incorrect. Anyway, the mainstream claims that if the government is willing to increase the money growth rate it can finance a growing deficit but also inflation because there will be too much money chasing too few goods! But an economy constrained by deficient demand (defined as demand below the full employment level) responds to a nominal impulse by expanding real output not prices.
But because they believe that inflation is inevitable if "printing money" occurs, mainstream economists recommend that governments use debt issuance to "finance" their deficits. But then they scream that this will merely require higher future taxes. Why should taxes have to be increased?
Well the textbooks are full of elaborate models of debt pay-back, debt stabilisation etc which all "prove" (not!) that the legacy of past deficits is higher debt and to stabilise the debt, the government must eliminate the deficit which means it must then run a primary surplus equal to interest payments on the existing debt.
Nothing is included about the swings and roundabouts provided by the automatic stabilisers as the results of the deficits stimulate private activity and welfare spending drops and tax revenue rises automatically in line with the increased economic growth. Most orthodox models are based on the assumption of full employment anyway, which makes them nonsensical depictions of the real world.
More sophisticated mainstream analyses focus on the ratio of debt to GDP rather than the level of debt per se. They come up with the following equation - nothing that they now disregard the obvious opportunity presented to the government via ΔH. So in the following model all net public spending is covered by new debt-issuance (even though in a fiat currency system no such financing is required).
Accordingly, the change in the public debt ratio is:
The change in the debt ratio is the sum of two terms on the right-hand side: (a) the difference between the real interest rate (r) and the GDP growth rate (g) times the initial debt ratio; and (b) the ratio of the primary deficit (G-T) to GDP.
A growing economy can absorb more debt and keep the debt ratio constant. For example, if the primary deficit is zero, debt increases at a rate r but the debt ratio increases at r - g.
So a change in the change in the debt ratio is the sum of two terms on the right-hand side: (a) the difference between the real interest rate (r) and the GDP growth rate (g) times the initial debt ratio; and (b) the ratio of the primary deficit (G-T) to GDP.
As we noted a growing economy can absorb more debt and keep the debt ratio constant. For example, if the primary deficit is zero, debt increases at a rate r but the debt ratio increases at r - g.
Consider the following table which simulates two different scenarios. Case A shows a real interest rate of zero and a steadily increasing annual GDP growth rate across 10 years. The initial public debt ratio is 100 per cent (so well over the level Reinhart and Rogoff claim is the point of no return and insolvency is pending). The budget deficit is also simulated to be 5 per cent of GDP then reduces as the GDP growth induce the automatic stabilisers. It then reaches a steady 2 per cent per annum which might be sufficient to support the saving intentions of the non-government sector while still promoting steady economic growth.
You can see that the even with a continuous deficit, the public debt ratio declines steadily and would continue to do so as the growth continued. The central bank could of-course cut the nominal interest rate to speed the contraction in the debt ratio although I would not undertake that policy change for that reason.
In Case B we assume that the government stops issuing debt with everything else the same. The public debt ratio drops very quickly under this scenario.
However, should the real interest rate exceed the economic growth rate, then unless the primary budget balance offsets the rising interest payments as percent of GDP, then the public debt ratio will rise.
The only concern I would have in this situation does not relate to the rising ratio. Focusing on the cause should be the policy concern. If the real economy is faltering because interest rates are too high or more likely because the primary budget deficit is too low then the rising public debt ratio is just telling us that the central bank should drop interest rates or the treasury should increase the discretionary component of the budget.
In general though, the public debt ratio is a relatively uninteresting macroeconomic figure and should be disregarded. If the government is intent on promoting growth, then the primary deficit ratio and the public debt ratio will take care of themselves.
