The BBC podcast linked below looks at the use of quantitative easing since 2009 and especially the most recent round since the onset of the pandemic.

Although QE was a major contributor to reducing the depth of the recession in 2009–10, it was barely used from 2013 to 2020 (except for a short period in late 2016/early 2017). The Coalition and Conservative governments were keen to get the deficit down. In justifying pay restraint and curbing government expenditure, Prime Ministers David Cameron and Theresa May both argued that there ‘was no magic money tree’.

But with the severely dampening effect of the lockdown measures from March 2020, the government embarked on a large round of expenditure, including the furlough scheme and support for businesses.

The resulting rise in the budget deficit was accompanied by a new round of QE from the beginning of April. The stock of assets purchased by the Bank of England rose from £445 billion (the approximate level it had been since March 2017) to £740 billion by December 2020 and is planned to reach £895 billion by the end of 2021.

So with the effective funding of the government’s deficits by the creation of new money, does this mean that there is indeed a ‘magic money tree’ or, indeed, a ‘magic money forest’? And if so, is it desirable? Is it simply stoking up problems for the future? Or will, as modern monetary theorists maintain, the extra money, if carefully spent, lead to faster growth and a reducing deficit, with low interest rates making it easy to service the debt?

The podcast explores these issues. There is then a longer list of questions than normal relating to the topics raised in the podcast.

Back in June, we examined the macroeconomic forecasts of the three agencies, the IMF, the OECD and the European Commission, all of which publish forecasts every six months. The IMF has recently published its latest World Economic Outlook (WEO) and its accompanying database. Unlike the April WEO, which, given the huge uncertainty surrounding the pandemic and its economic effects, only forecast as far as 2021, the latest version forecasts as far ahead as 2025.

In essence the picture is similar to that painted in April. The IMF predicts a large-scale fall in GDP and rise in unemployment, government borrowing and government debt for 2020 (compared with 2019) across virtually all countries.

World real GDP is predicted to fall by 4.4%. For many countries the fall will be much steeper. In the UK, GDP is predicted to fall by 9.8%; in the eurozone, by 8.3%; in India, by 10.3%; in Italy, by 10.8%; in Spain, by 12.8%. There will then be somewhat of a ‘bounce back’ in GDP in 2021, but not to the levels of 2019. World real GDP is predicted to rise by 5.2% in 2021. (Click here for a PowerPoint of the growth chart.)

Unemployment will peak in some countries in 2020 and in others in 2021 depending on the speed of recovery from recession and the mobility of labour. (Click here for a PowerPoint of the unemployment chart.)

Inflation is set to fall from already low levels. Several countries are expected to see falling prices.

Government deficits (negative net lending) will be sharply higher in 2020 as a result of government measures to support workers and firms affected by lockdowns and falling demand. Governments will also receive reduced tax revenues. (Click here for a PowerPoint of the general government net lending chart.)

Government debt will consequently rise more rapidly. Deficits are predicted to fall in 2021 as economies recover and hence the rise in debt will slow down or in some cases, such as Germany, even fall. (Click here for a PowerPoint of the general government gross debt chart.)

After the rebound in 2021, global growth is then expected to slow to around 3.5% by 2025. This compares with an average of 3.8% from 2000 to 2019. Growth of advanced economies is expected to slow to 1.7%. It averaged 1.9% from 2000 to 2019. For emerging market and developing countries it is expected to slow to 4.7% from an average of 5.7% from 2000 to 2019. These figures suggest some longer-term scarring effects from the pandemic.


In the short term, the greatest uncertainty concerns the extent of the second wave, the measures put in place to contain the spread of the virus and the compensation provided by governments to businesses and workers. The WEO report was prepared when the second wave was only just beginning. It could well be that countries will experience a deeper recession in 2000 and into 2021 than predicted by the IMF.

This is recognised in the forecast.

The persistence of the shock remains uncertain and relates to factors inherently difficult to predict, including the path of the pandemic, the adjustment costs it imposes on the economy, the effectiveness of the economic policy response, and the evolution of financial sentiment.

With some businesses forced to close, others operating at reduced capacity because of social distancing in the workplace and with dampened demand, many countries may find output falling again. The extent will to a large extent depend on the levels of government support.

In the medium term, it is assumed that there will be a vaccine and that economies can begin functioning normally again. However, the report does recognise the long-term scarring effects caused by low levels of investment, deskilling and demotivation of the parts of the workforce, loss of capacity and disruptions to various supply chains.

The deep downturn this year will damage supply potential to varying degrees across economies. The impact will depend on various factors … including the extent of firm closures, exit of discouraged workers from the labour force, and resource mismatches (sectoral, occupational and geographic).

One of the greatest uncertainties in the medium term concerns the stance of fiscal and monetary policies. Will governments continue to run large deficits to support demand or will they attempt to reduce deficits by raising taxes and/or reducing benefits and/or cutting government current or capital expenditure?

Will central banks continue with large-scale quantitative easing and ultra-low or even negative interest rates? Will they use novel forms of monetary policy, such as directly funding government deficits with new money or providing money directly to citizens through a ‘helicopter’ scheme (see the 2016 blog, New UK monetary policy measures – somewhat short of the kitchen sink)?

Forecasting at the current time is fraught with uncertainty. However, reports such as the WEO are useful in identifying the various factors influencing the economy and how seriously they may impact on variables such as growth, unemployment and government deficits.

In the current environment of low inflation and rising unemployment, the Federal Reserve Bank, the USA’s central bank, has amended its monetary targets. The new measures were announced by the Fed chair, Jay Powell, in a speech for the annual Jackson Hole central bankers’ symposium (this year conducted online on August 27 and 28). The symposium was an opportunity for central bankers to reflect on their responses to the coronavirus pandemic and to consider what changes might need to be made to their monetary policy targets and instruments.

The Fed’s previous targets

Previously, like most other central banks, the Fed had a long-run inflation target of 2%. It did, however, also seek to ‘maximise employment’. In practice, this meant seeking to achieve a ‘normal’ rate of unemployment, which the Fed regards as ranging from 3.5 to 4.7% with a median value of 4.1%. The description of its objectives stated that:

In setting monetary policy, the Committee seeks to mitigate deviations of inflation from its longer-run goal and deviations of employment from the Committee’s assessments of its maximum level. These objectives are generally complementary. However, under circumstances in which the Committee judges that the objectives are not complementary, it follows a balanced approach in promoting them, taking into account the magnitude of the deviations and the potentially different time horizons over which employment and inflation are projected to return to levels judged consistent with its mandate.

The new targets

Under the new system, the Fed has softened its inflation target. It will still be 2% over the longer term, but it will be regarded as an average, rather than a firm target. The Fed will be willing to see inflation above 2% for longer than previously before raising interest rates if this is felt necessary for the economy to recover and to achieve its long-run potential economic growth rate. Fed chair, Jay Powell, in a speech on 27 August said:

Following periods when inflation has been running below 2%, appropriate monetary policy will likely aim to achieve inflation moderately above 2 per cent for some time.

Additionally, the Fed has increased its emphasis on employment. Instead of focusing on deviations from normal employment, the Fed will now focus on the shortfall of employment from its normal level and not be concerned if employment temporarily exceeds its normal level. As Powell said:

Going forward, employment can run at or above real-time estimates of its maximum level without causing concern, unless accompanied by signs of unwanted increases in inflation or the emergence of other risks that could impede the attainment of our goals

The Fed will also take account of the distribution of employment and pay more attention to achieving a strong labour market in low-income and disadvantaged communities. However, apart from the benefits to such communities from a generally strong labour market, it is not clear how the Fed could focus on disadvantaged communities through the instruments it has at its disposal – interest rate changes and quantitative easing.


Modern monetary theorists (see blog MMT – a Magic Money Tree or Modern Monetary Theory?) will welcome the changes, arguing that they will allow more aggressive expansion and higher government borrowing at ultra-low interest rates.

The problem for the Fed is that it is attempting to achieve more aggressive goals without having any more than the two monetary instruments it currently has – lowering interest rates and increasing money supply through asset purchases (quantitative easing). Interest rates are already near rock bottom and further quantitative easing may continue to inflate asset prices (such as share and property prices) without sufficiently stimulating aggregate demand. Changing targets without changing the means of achieving them is likely to be unsuccessful.

It remains to be seen whether the Fed will move to funding government borrowing directly, which could allow for a huge stimulus through infrastructure spending, or whether it will merely stick to using asset purchases as a way for introducing new money into the system.




  1. Find out how much asset purchases by the Fed, the Bank of England and the ECB have increased in the current rounds of quantitative easing.
  2. How do asset purchases affect narrow money, broad money and aggregate demand? Is there a fixed money multiplier effect between the narrow money increases and aggregate demand? Explain.
  3. Why did the dollar exchange rate fall following the announcement of the new measures by Jay Powell?
  4. The Governor of the Bank of England, Andrew Bailey, also gave a speech at the Jackson Hole symposium. How does the approach to money policy outlined by Bailey differ from that outlined by Jay Powell?
  5. What practical steps, if any, could a central bank take to improve the relative employment prospects of disadvantaged groups?
  6. Outline the arguments for and against central banks directly funding government expenditure through money creation.
  7. What longer-term problems are likely to arise from central banks pursuing ultra-low interest rates for an extended period of time?

Is there a ‘magic money tree’? Is it desirable for central banks to create money to finance government deficits?

The standard thinking of conservative governments around the world is that creating money to finance deficits will be inflationary. Rather, governments should attempt to reduce deficits. This will reduce the problem of government expenditure crowding out private expenditure and reduce the burden placed on future generations of having to finance higher government debt.

If deficits rise because of government response to an emergency, such as supporting people and businesses during the Covid-19 pandemic, then, as soon as the problem begins to wane, governments should attempt to reduce the higher deficits by raising taxes or cutting government expenditure. This was the approach of many governments, including the Coalition and Conservative governments in the UK from 2010, as econommies began to recover from the 2007/8 financial crisis.

Modern Monetary Theory‘ challenges these arguments. Advocates of the theory support the use of higher deficits financed by monetary expansion if the money is spent on things that increase potential output as well as actual output. Examples include spending on R&D, education, infrastructure, health and housing.

Modern monetary theorists still accept that excess demand will lead to inflation. Governments should therefore avoid excessive deficits and central banks should avoid creating excessive amounts of money. But, they argue that inflation caused by excess demand has not been a problem for many years in most countries. Instead, we have a problem of too little investment and too little spending generally. There is plenty of scope, they maintain, for expanding demand. This, if carefully directed, can lead to productivity growth and an expansion of aggregate supply to match the rise in aggregate demand.

Government deficits, they argue, are not intrinsically bad. Government debt is someone else’s assets, whether in the form of government bonds, savings certificates, Treasury bills or other instruments. Provided the debt can be serviced at low interest rates, there is no problem for the government and the spending it generates can be managed to allow economies to function at near full capacity.
