With the imposition of a new lockdown in England from 5 November to 2 December and in Wales from 3 October to 9 November, and with strong restrictions in Scotland and Northern Ireland, the UK economy is set to return to negative growth – a W-shaped GDP growth curve.
With the closure of leisure facilities and non-essential shops in England and Wales, spending is likely to fall. Without support, many businesses would fail and potential output would fall. In terms of aggregate demand and supply, both would decline, as the diagram below illustrates. (Click here for a PowerPoint.)
The aggregate demand curve shifts from AD1 to AD2 as consumption and investment fall. Exports also fall as demand is hit by the pandemic in other countries.
The fall in aggregate supply is represented partly by a movement along the short-run aggregate supply curve (SRAS) as demand falls for businesses which remain open (such as transport services). Largely it is represented by a leftward shift in the curve from SRAS1 to SRAS2 as businesses such as non-essential shops and those in the hospitality and leisure sector are forced to close. What happens to the long-run supply curve depends on the extent to which businesses reopen when the lockdown and any other subsequent restrictions preventing their reopening are over. It also depends on the extent to which other firms spring up or existing firms grow to replace the business of those that have closed. The continuing rise in online retailing is an example.
With the prospect of falling GDP and rising unemployment, the UK government and the Bank of England have responded by giving a fiscal and monetary boost. We examine each in turn.
Fiscal policy
In March, the Chancellor introduced the furlough scheme, whereby employees temporarily laid off would receive 80% of their wages through a government grant to their employers. This scheme was due to end on 31 October, to be replaced by the less generous Job Support Scheme (see the blog, The new UK Job Support Scheme: how much will it slow the rise in unemployment?). However, the Chancellor first announced that the original furlough scheme would be extended until 2 December for England and then, on 5 November, to the end of March 2021 for the whole of the UK. He also announced that the self-employed income support grant would increase from 55% to 80% of average profits up to £7500.
In addition, the government announced cash grants of up to £3000 per month for businesses which are closed (worth more than £1 billion per month), extra money to local authorities to support businesses and an extension of existing loan schemes for business. Furthermore, the government is extending the scheme whereby people can claim a repayment ‘holiday’ for up to 6 months for mortgages, personal loans and car finance.
The government hopes that the boost to aggregate demand will help to slow, or even reverse, the predicted decline in GDP. What is more, by people being put on furlough rather than being laid off, it hopes to slow the rise in unemployment.
Monetary policy
At the meeting of the Bank of England’s Monetary Policy Committee on 4 November, further expansionary monetary policy was announced. Rather than lowering Bank Rate from its current historically low rate of 0.1%, perhaps to a negative figure, it was decided to engage in further quantitative easing.
An additional £150 billion of government bonds will be purchased under the asset purchase facility (APF). This will bring the total vale of bonds purchased since the start of the pandemic to £450 billion (including £20 billion of corporate bonds) and to £895 billion since 2009 when QE was first introduced in response to the recession following the financial crisis of 2007–8.
The existing programme of asset purchases should be complete by the end of December this year. The Bank of England expects the additional £150 billion of purchases to begin in January 2021 and be completed within a year.
UK quantitative easing since the first round in March 2009 is shown in the chart above. The reserve liabilities represent the newly created money for the purchase of assets under the APF programme. (There are approximately £30 billion of other reserve liabilities outside the APF programme.) The grey area shows projected reserve liabilities to the end of the newly announced programme of purchases, by which time, as stated above, the total will be £895 billion. This, of course, assumes that the Bank does not announce any further QE, which it could well do if the recovery falters.

Justifying the decision, the MPC meeting’s minutes state that:
There are signs that consumer spending has softened across a range of high-frequency indicators, while investment intentions have remained weak. …The fall in activity over 2020 has reflected a decline in both demand and supply. Overall, there is judged to be a material amount of spare capacity in the economy.
Conclusions
How effective these fiscal and monetary policy measures will be in mitigating the effects of the Covid restrictions remains to be seen. A lot will depend on how successful the lockdown and other restrictions are in slowing the virus, how quickly a vaccine is developed and deployed, whether a Brexit deal is secured, and the confidence of both consumers, businesses and financial markets that the economy will bounce back in 2021. As the MPC’s minutes state:
The outlook for the economy remains unusually uncertain. It depends on the evolution of the pandemic and measures taken to protect public health, as well as the nature of, and transition to, the new trading arrangements between the European Union and the United Kingdom. It also depends on the responses of households, businesses and financial markets to these developments.

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.
Assessment
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.

Share prices are determined by demand and supply. The same applies to stock market indices, such as the FTSE 100 and FTSE 250 in the UK and the Dow Jones Industrial Average and the S&P 500 in the USA. After all, the indices are the weighted average prices of the shares included in the index. Generally, when economies are performing well, or are expected to do so, share prices will rise. They are likely to fall in a recession or if a recession is anticipated. A main reason for this is that the dividends paid on shares will reflect the profitability of firms, which tends to rise in times of a buoyant economy.
When it first became clear that Covid-19 would become a pandemic and as countries began locking down, so stock markets plummeted. People anticipated that many businesses would fail and that the likely recession would cause profits of many other surviving firms to decline rapidly. People sold shares.
The first chart shows how the FTSE 100 fell from 7466 in early February 2020 to 5190 in late March, a fall of 30.5%. The Dow Jones fell by 34% over the same period. In both cases the fall was driven not only by the decline in the respective economy over the period, but by speculation that further declines were to come (click here for a PowerPoint of the chart).
But then stock markets started rising again, especially the Dow Jones, despite the fact that the recessions in the UK, the USA and other countries were gathering pace. In the second quarter of 2020, the Dow Jones rose by 23% and yet the US economy declined by 33% – the biggest quarterly decline on record. How could this be explained by supply and demand?
Quantitative easing
In order to boost aggregate demand and reduce the size of the recession, central banks around the world engaged in large-scale quantitative easing.
This involves central banks buying government bonds and possibly corporate bonds too with newly created money. The extra money is then used to purchase other assets, such as stocks and shares and property, or physical capital or goods and services. The second chart shows that quantitative easing by the Bank of England increased the Bank’s asset holding from April to July 2020 by 50%, from £469bn to £705bn (click here for a PowerPoint of the chart).
But given the general pessimism about the state of the global economy, employment and personal finances, there was little feed-through into consumption and investment. Instead, most of the extra money was used to buy assets. This gave a huge boost to stock markets. Stock market movements were thus out of line with movements in GDP.
Confidence
Stock market prices do not just reflect the current economic and financial situation, but also what people anticipate the situation to be in the future.
As infection and death rates from Covid-19 waned around Europe and in many other countries, so consumer and business confidence rose. This is illustrated in the third chart, which shows industrial, consumer and construction confidence indicators in the EU. As you can see, after falling sharply as the pandemic took hold in early 2020 and countries were locked down, confidence then rose (click here for a PowerPoint of the chart).
But, as infection rates have risen somewhat in many countries and continue to soar in the USA, Brazil, India and some other countries, this confidence may well start to fall again and this could impact on stock markets.
Speculation
A final, but related, cause of recent stock market movements is speculation. If people see share prices falling and believe that they are likely to fall further, then they will sell shares and hold cash or safer assets instead. This will amplify the fall and encourage further speculation. If, however, they see share prices rising and believe that they will continue to do so, they are likely to want to buy shares, hoping to make a gain by buying them relatively cheaply. This will amplify the rise and, again, encourage further speculation.
If there is a second wave of the pandemic, then stock markets could well fall again, as they could if speculators think that share prices have overshot the levels that reflect the economic and financial situation. But then there may be even further quantitative easing.
There are many uncertainties, both with the pandemic and with governments’ policy responses. These make forecasting stock market movements very difficult. Large gains or large losses could await people speculating on what will happen to share prices.

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.
The following videos and articles look at modern monetary theory and assess its relevance. Not surprisingly, they differ in their support of the theory!

At its meeting on 6 May, the Bank of England’s Monetary Policy Committee decided to keep Bank Rate at 0.1%. Due to the significant impact of COVID-19 and the measures put in place to try to contain the virus, the MPC voted unanimously to keep Bank Rate the same.
However, it decided not to launch a new stimulus programme, with the committee voting by a majority of 7-2 for the Bank to continue with the current programme of quantitative easing. This involves the purchase of £200 billion of government and sterling non-financial investment-grade corporate bonds, bringing the total stock of bonds held by the Bank to £645 billion.
The Bank forecast that the crisis will put the economy into its deepest recession in 300 years, with output plunging 30 per cent in the first half of the year.
Monetary policy and MPC
Monetary policy is the tool used by the UK’s central bank to influence how much money is in the economy and how much it costs to borrow. The Bank of England’s main monetary policy tools include setting the Bank Rate and quantitative easing (QE). Bank Rate is the interest rate charged to banks when they borrow money from the BoE. QE is the process of creating money digitally to buy corporate and government bonds.
The BoE’s Monetary Policy Committee (MPC) sets monetary policy to meet the 2% inflation target. Maintaining a low and stable inflation rate is good for the economy and it is the main monetary policy aim. However, the Bank also has to balance this target with the government’s other economic aims of sustaining growth and employment in the economy.
Actions taken by the MPC
It is challenging to respond to severe economic and financial disruption, with the UK economy looking unusually uncertain. Activity has fallen sharply since the beginning of the year and unemployment has risen markedly. The current rate of inflation, measured by the Consumer Price Index (CPI), declined to 1.5% in March and is likely to fall below 1% in the next few months. Household consumption has fallen by around 30% as consumer confidence has declined. Companies’ sales are expected to be around 45% lower than normal and business investment 50% lower.
In the current circumstances, and consistent with the MPC’s remit, monetary policy is aimed at supporting businesses and households through the crisis and limiting any lasting damage to the economy. The Bank has used both main monetary tools to fulfil its mandate and attempt to boost the economy amid the current lockdown. The Bank Rate was reduced to 0.1% in March, the lowest level in the Bank’s 325-year history and the current programme of QE was introduced in March.
What is next?
This extraordinary time has seen the outlook for the all global economies become uncertain.
The long-term outcome will depend critically on the evolution of the pandemic, and how governments, households and businesses respond to it. The Bank of England has stated that businesses and households will need to borrow to get through this period and is encouraging banks and building societies to increase their lending. Britain’s banks are warned that if they try to stem losses by restricting lending, they will make the situation worse. The Bank believes that the banks are strong enough to keep lending, which will support the economy and limit losses to themselves.
In the short term, a bleak picture of the UK economy is suggested, with a halving in business investment, a near halving in business sales, a sharp rise in unemployment and households cutting their spending by a third. Despite its forecast that GDP could shrink by 14% for 2020, the Bank of England is forecasting a ‘V’ shaped recovery. In this scenario, the recovery in economic activity, once measures are softened, is predicted to be relatively rapid and inflation rises to around the 2 per cent target. However, this would be after a dip to 0.5% in 2021, before returning to the 2 per cent target the following year.
However, there are some suggestions that the Bank’s forecast for the long-term recovery is too optimistic. Yael Selfin, chief economist at KPMG UK, fears the UK economy could shrink even more sharply than the Bank of England has forecast.
Despite the stark numbers issued by the Bank of England today, additional pressure on the economy is likely. Some social distancing measures are likely to remain in place until we have a vaccine or an effective treatment for the virus, with people also remaining reluctant to socialise and spend. That means recovery is unlikely to start in earnest before sometime next year.
There are also additional factors that could dampen future productivity, such as the impact on supply chains, with ‘just-in-time’ operations potentially being a thing of the past.
There is also the ongoing issue of Brexit. This is a significant downside risk as the probability of a smooth transition to a comprehensive free-trade agreement with the EU in January is relatively small. This will only increase uncertainty for businesses along with the prospect of increased trade frictions next year.
Conclusion
The predictions from the Bank of England are based on many assumptions, one of which is that the economy will only be gradually released from lockdown. Its numbers contain the expectations that consumer and worker behaviour will change significantly, and continue for some time, with forms of voluntary social distancing. On the other hand, Mr Bailey expects the recovery to be much faster than seen with the financial crisis a decade ago. However, again this is based on the assumption that measures put in place from the public health side prevent a second wave of the virus.
It also assumes that the supply-side effects on the economy will be limited in the long run. Many economists disagree, arguing that the ‘scarring effects’ of the lockdown may be substantial. These include lower rates of investment, innovation and start ups and the deskilling effects on labour. They also include the businesses that have gone bankrupt and the dampening effect on consumer and business confidence. Finally, with a large increase in lending to tide firms over the crisis, many will face problems of debt, which will dampen investment.
The Bank of England does recognise these possible scarring effects. Specifically, it warns of the danger of a rise in equilibrium unemployment:
It is possible that the rise in unemployment could prove more persistent than embodied in the scenario, for example if companies are reluctant to hire until they are sure about the robustness of the recovery in demand. It is also possible that any rise in unemployment could lead to an increase in the long‑term equilibrium rate of unemployment. That might happen if the skills of the unemployed do not increase to the same extent as they would if they were working, for example, or even erode over time.
What is certain, however, is that the long-term picture will only become clearer when we start to come out of the crisis. Bailey implied that the Bank is taking a wait-and-see approach for now, waiting on the UK government to shed some light about easing of lockdown measures before taking any further action with regards to QE. The MPC will continue to monitor the situation closely and, consistent with its remit, stands ready to take further action as necessary to support the economy and ensure a sustained return of inflation to the 2% target. Paul Dales, chief UK economist at Capital Economics, suggested that the central bank is signalling that ‘more QE is coming, if not in June, then in August’.
