The Weekend Quiz – July 20-21, 2019 – answers and discussion

Here are the answers with discussion for this Weekend’s Quiz. The information provided should help you work out why you missed a question or three! If you haven’t already done the Quiz from yesterday then have a go at it before you read the answers. I hope this helps you develop an understanding of Modern Monetary Theory (MMT) and its application to macroeconomic thinking. Comments as usual welcome, especially if I have made an error.

Question 1:

For nations enjoying strong terms of trade (and external surplus), it is sensible for the government to run fiscal surpluses and accumulate them in a sovereign fund to create more space for non-inflationary spending in the future.

The answer is False.

The fundamental principles that arise in a fiat monetary system are as follows:

  • The central bank sets the short-term interest rate based on its policy aspirations.
  • Government spending capacity is independent of taxation revenue. The non-government sector cannot pay taxes until the government has spent.
  • Government spending capacity is independent of borrowing which the latter best thought of as coming after spending.
  • Government spending provides the net financial assets (bank reserves) which ultimately represent the funds used by the non-government agents to purchase the debt.
  • Fiscal deficits put downward pressure on interest rates contrary to the myths that appear in macroeconomic textbooks about “crowding out”.
  • The “penalty for not borrowing” is that the interest rate will fall to the bottom of the “corridor” prevailing in the country which may be zero if the central bank does not offer a return on reserves.
  • Government debt-issuance is a “monetary policy” operation rather than being intrinsic to fiscal policy, although in a modern monetary paradigm the distinctions between monetary and fiscal policy as traditionally defined are moot.

These principles apply to all sovereign, currency-issuing governments irrespective of whether there is a strong external sector or not.

The mistake lies in thinking that such a government is revenue-constrained and that a booming mining sector, for example, delivers more revenue and thus gives the government more spending capacity.

Nothing could be further from the truth irrespective of the rhetoric that politicians use to relate their fiscal decisions to us and/or the institutional arrangements that they have put in place which make it look as if they are raising money to re-spend it!

These things are veils to disguise the true capacity of a sovereign government in a fiat monetary system.

In the midst of the nonsensical intergenerational (ageing population) debate, which is being used by conservatives all around the world as a political tool to justify moving to fiscal surpluses, the notion arises that governments will not be able to honour their liabilities to pensions, health etc unless drastic action is taken.

Hence the hype and spin moved into overdrive to tell us how the establishment of sovereign funds.

The financial markets love the creation of sovereign funds because they know there will be more largesse for them to speculate with at the expense of public spending.

Corporate welfare is always attractive to the top end of town while they draft reports and lobby governments to get rid of the Welfare state, by which they mean the pitiful amounts we provide to sustain at minimal levels the most disadvantaged among us.

The claim is that the creation of these sovereign funds create the fiscal room to fund the so-called future liabilities. Clearly this is nonsense.

A sovereign government’s ability to make timely payment of its own currency is never numerically constrained. So it would always be able to fund the pension liabilities, for example, when they arose without compromising its other spending ambitions.

The creation of sovereign funds basically involve the government becoming a financial asset speculator. So national governments start gambling in the World’s bourses usually at the same time as millions of their citizens do not have enough work.

The logic surrounding sovereign funds is also blurred. If one was to challenge a government which was building a sovereign fund but still had unmet social need (and perhaps persistent labour underutilisation) the conservative reaction would be that there was no fiscal room to do any more than they are doing.

Yet when they create the sovereign fund the government spends in the form of purchases of financial assets.

So we have a situation where the elected national government prefers to buy financial assets instead of buying all the labour that is left idle by the private market, for example. They prefer to hold bits of paper than putting all this labour to work to develop communities and restore our natural environment.

An understanding of Modern Monetary Theory (MMT) will tell you that all the efforts to create sovereign funds are totally unnecessary. Whether the fund gained or lost makes no fundamental difference to the underlying capacity of the national government to fund all of its future liabilities.

A sovereign government’s ability to make timely payment of its own currency is never numerically constrained by revenues from taxing and/or borrowing. Therefore the creation of a sovereign fund in no way enhances the government’s ability to meet future obligations. In fact, the entire concept of government pre-funding an unfunded liability in its currency of issue has no application whatsoever in the context of a flexible exchange rate and the modern monetary system.

The misconception that “public saving” is required to fund future public expenditure is often rehearsed in the financial media.

First, running fiscal surpluses does not create national savings. There is no meaning that can be applied to a sovereign government “saving its own currency”. It is one of those whacko mainstream macroeconomics ideas that appear to be intuitive but have no application to a fiat currency system.

In rejecting the notion that public surpluses create a cache of money that can be spent later we note that governments spend by crediting bank accounts. There is no revenue constraint. Government cheques don’t bounce! Additionally, taxation consists of debiting an account at an RBA member bank. The funds debited are “accounted for” but don’t actually “go anywhere” and “accumulate”.

The concept of pre-funding future liabilities does apply to fixed exchange rate regimes, as sufficient reserves must be held to facilitate guaranteed conversion features of the currency. It also applies to non-government users of a currency. Their ability to spend is a function of their revenues and reserves of that currency.

So at the heart of all this nonsense is the false analogy neo-liberals draw between private household budgets and the government fiscal capacity.

Households, the users of the currency, must finance their spending prior to the fact.

However, government, as the issuer of the currency, must spend first (credit private bank accounts) before it can subsequently tax (debit private accounts). Government spending is the source of the funds the private sector requires to pay its taxes and to net save and is not inherently revenue constrained.

Question 2:

A sovereign national government, that is, one that issues its own floating currency faces no solvency risk with respect to the debt it issues.

The answer is False.

The answer would be true if the sentence had added (to the debt it issues) … in its own currency. The national government can always service its debts so long as these are denominated in domestic currency.

It also makes no significant difference for solvency whether the debt is held domestically or by foreign holders because it is serviced in the same manner in either case – by crediting bank accounts.

The situation changes when the government issues debt in a foreign-currency. Given it does not issue that currency then it is in the same situation as a private holder of foreign-currency denominated debt.

Private sector debt obligations have to be serviced out of income, asset sales, or by further borrowing. This is why long-term servicing is enhanced by productive investments and by keeping the interest rate below the overall growth rate.

Private sector debts are always subject to default risk – and should they be used to fund unwise investments, or if the interest rate is too high, private bankruptcies are the “market solution”.

Only if the domestic government intervenes to take on the private sector debts does this then become a government problem. Again, however, so long as the debts are in domestic currency (and even if they are not, government can impose this condition before it takes over private debts), government can always service all domestic currency debt.

The solvency risk the private sector faces on all debt is inherited by the national government if it takes on foreign-currency denominated debt. In those circumstances it must have foreign exchange reserves to allow it to make the necessary repayments to the creditors. In times when the economy is strong and foreigners are demanding the exports of the nation, then getting access to foreign reserves is not an issue.

But when the external sector weakens the economy may find it hard accumulating foreign currency reserves and once it exhausts its stock, the risk of national government insolvency becomes real.

Question 3:

It would be impossible for a central bank to directly purchase treasury debt to facilitate the national government’s fiscal deficit while still targeting a positive short-term policy rate.

The answer is False.

The central bank conducts what are called liquidity management operations for two reasons. First, it has to ensure that all private cheques (that are funded) clear and other interbank transactions occur smoothly as part of its role of maintaining financial stability. Second, it must maintain aggregate bank reserves at a level that is consistent with its target policy setting given the relationship between the two.

So operating factors link the level of reserves to the monetary policy setting under certain circumstances. These circumstances require that the return on “excess” reserves held by the banks is below the monetary policy target rate. In addition to setting a lending rate (discount rate), the central bank also sets a support rate which is paid on commercial bank reserves held by the central bank.

Commercial banks maintain accounts with the central bank which permit reserves to be managed and also the clearing system to operate smoothly. In addition to setting a lending rate (discount rate), the central bank also can set a support rate which is paid on commercial bank reserves held by the central bank (which might be zero).

Many countries (such as Australia, Canada and zones such as the European Monetary Union) maintain a default return on surplus reserve accounts (for example, the Reserve Bank of Australia pays a default return equal to 25 basis points less than the overnight rate on surplus Exchange Settlement accounts). Other countries like Japan and the US have typically not offered a return on reserves until the onset of the current crisis.

If the support rate is zero then persistent excess liquidity in the cash system (excess reserves) will instigate dynamic forces which would drive the short-term interest rate to zero unless the government sells bonds (or raises taxes). This support rate becomes the interest-rate floor for the economy.

The short-run or operational target interest rate, which represents the current monetary policy stance, is set by the central bank between the discount and support rate. This effectively creates a corridor or a spread within which the short-term interest rates can fluctuate with liquidity variability. It is this spread that the central bank manages in its daily operations.

In most nations, commercial banks by law have to maintain positive reserve balances at the central bank, accumulated over some specified period. At the end of each day commercial banks have to appraise the status of their reserve accounts. Those that are in deficit can borrow the required funds from the central bank at the discount rate.

Alternatively banks with excess reserves are faced with earning the support rate which is below the current market rate of interest on overnight funds if they do nothing.

Clearly it is profitable for banks with excess funds to lend to banks with deficits at market rates.

Competition between banks with excess reserves for custom puts downward pressure on the short-term interest rate (overnight funds rate) and depending on the state of overall liquidity may drive the interbank rate down below the operational target interest rate. When the system is in surplus overall this competition would drive the rate down to the support rate.

The main instrument of this liquidity management is through open market operations, that is, buying and selling government debt.

When the competitive pressures in the overnight funds market drives the interbank rate below the desired target rate, the central bank drains liquidity by selling government debt.

This open market intervention therefore will result in a higher value for the overnight rate. Importantly, we characterise the debt-issuance as a monetary policy operation designed to provide interest-rate maintenance.

This is in stark contrast to orthodox theory which asserts that debt-issuance is an aspect of fiscal policy and is required to finance deficit spending.

Accordingly, debt is issued as an interest-maintenance strategy by the central bank. It has no correspondence with any need to fund government spending. Debt might also be issued if the government wants the private sector to have less purchasing power.

Further, the idea that governments would simply get the central bank to “monetise” treasury debt (which is seen orthodox economists as the alternative “financing” method for government spending) is highly misleading. Debt monetisation is usually referred to as a process whereby the central bank buys government bonds directly from the treasury.

In other words, the federal government borrows money from the central bank rather than the public. Debt monetisation is the process usually implied when a government is said to be printing money. Debt monetisation, all else equal, is said to increase the money supply and can lead to severe inflation.

However, as long as the central bank has a mandate to maintain a target short-term interest rate, the size of its purchases and sales of government debt are not discretionary. Once the central bank sets a short-term interest rate target, its portfolio of government securities changes only because of the transactions that are required to support the target interest rate.

The central bank’s lack of control over the quantity of reserves underscores the impossibility of debt monetisation. The central bank is unable to monetise the federal debt by purchasing government securities at will because to do so would cause the short-term target rate to fall to zero or to the support rate. If the central bank purchased securities directly from the treasury and the treasury then spent the money, its expenditures would be excess reserves in the banking system. The central bank would be forced to sell an equal amount of securities to support the target interest rate.

The central bank would act only as an intermediary. The central bank would be buying securities from the treasury and selling them to the public. No monetisation would occur.

However, the central bank may agree to pay the short-term interest rate to banks who hold excess overnight reserves. This would eliminate the need by the commercial banks to access the interbank market to get rid of any excess reserves and would allow the central bank to maintain its target interest rate without issuing debt.

  1. “Government debt-issuance is a “monetary policy” operation rather than being intrinsic to fiscal policy, although in a modern monetary paradigm the distinctions between monetary and fiscal policy as traditionally defined are moot.” (From the answer to question 1)

    Is it moot because we consider the central bank to be an agent of the government? Can I still say MMT considers monetary policy to be a largely ineffective tool compared to fiscal policy? Cause that isn’t a small distinction that wouldn’t matter. (And it is one of the things I tell people when I try to explain MMT to them)

    As always- thanks for the quiz! I like to argue about it but I really learn a lot from it.

  2. Tricked by Q2 and assumed it was referring to debt denominated in the sovereign state’s fiat currency

  3. Concerning Q1, what if we assume that countries, especially developing countries, need to have dollar reserves in order to operate in the international system? Most developing countries are extremely dependent on the dollar in the sense that they are currency constrained in order to spend. Having sovereign funds would be understandable in this situation as it would be necessary to spend in dollars in order to obtain real resources from the external sector and employ the population.
