The COVID-19 pandemic had a stark effect on countries’ public finances. Governments had to make difficult fiscal choices around spending and taxation to safeguard public health, and the protection of jobs and incomes both in the present and in the future. The fiscal choices were to have historically large effects on the size of public spending and on the size of public borrowing. Here we briefly summarise the magnitude of these effects on public spending, receipts and borrowing in the UK.
The public sector comprises both national government and local or regional government. In financial year 2019/20 public spending in the UK was £886 billion. This would rise to £1.045 trillion in 2020/21. To understand better the magnitude of these figures we can express them as a share of national income (Gross Domestic Product). In 2019/20 public spending was 39.8 per cent of national income. This rose to 52.1 per cent in 2020/21. Meanwhile, public-sector receipts, largely taxation, fell from £829.1 billion in 2019/20 to £796.5 billion in 2020/21, though, because of the fall in national income, the share of receipts in national income rose very slightly from 37.3 to 37.9 per cent of national income.
The chart shows both public spending and public receipts as a share of national income since 1900. (Click here for a PowerPoint of the chart.) What this chart shows is the extraordinary impact of the two World Wars on the relative size of public spending. We can also see an uptick in public spending following the global financial crisis and, of course, the COVID-19 pandemic. The chart also shows that spending is typically larger than receipts meaning that the public sector typically runs a budget deficit. .
If we focus on public spending as a share of national income and its level following the two world wars, we can see that it did not fall back to pre-war levels. This is what Peacock and Wiseman (1961) famously referred to as a displacement effect. They attributed this to, among other things, an increase in the public’s tolerance to pay higher taxation because of the higher taxes levied during the war as well as to a desire for greater public intervention. The latter arose from an inspection effect. This can be thought of as a public consciousness effect, with the war helping to shine a light on a range of economic and social issues, such as health, housing and social security. These two effects, it is argued, reinforced each other, allowing the burden of taxation to rise and, hence, public spending to increase relative to national income.
If we forward to the global financial crisis, we can again see public spending rise as a share of national income. However, this time the ratio did not remain above pre-crisis levels. Rather, the UK government was fearful of unsustainable borrowing levels and the crowding out of private-sector activity by the public sector, with higher interest rates making public debt an attractive proposition for investors. It thus sought to reduce the public-sector deficit by engaging in what became known as ‘austerity’ measures.
If we move forward further to the COVID-19 pandemic, we see an even more significant spike in public spending as a share of national income. It is of course rather early to make predictions about whether the pandemic will have enduring effects on public spending and taxation. Nonetheless the pandemic, in a similar way to the two world wars, has sparked public debates on many economic and social issues. Whilst debates around the funding of health and social care are longstanding, it could be argued that the pandemic has provided the government with the opportunity to introduce the 1.25 percentage point levy from April 2022 on the earned incomes of workers (both employees and the self-employed) and on employers. (See John’s blog Fair care? for a fuller discussion on the tax changes to pay for increased health and social care expenditure).
The extent to which there may be a pandemic displacement effect will depend on the fiscal choices made in the months and years ahead. The key question is how powerful will be the effect of social issues like income and wealth inequality, regional and inter-generational disparities, discrimination, poor infrastructure and educational opportunities in shaping these fiscal choices? Will these considerations carry more weight than the push to consolidate the public finances and tighten the public purse? These fiscal choices will determine the extent of any displacement effect in public spending and taxation.

Rishi Sunak delivered his 2021 UK Budget on 3 March. It illustrates the delicate balancing act that governments in many countries face as the effects of the coronavirus pandemic persist and public-sector debt soars. He announced that he would continue supporting the economy through various forms of government expenditure and tax relief, but also announced tax rises over the medium term to begin addressing the massively increased public-sector debt.
Key measures of support for people and businesses include:
- An extension of the furlough scheme until the end of September, with employees continuing to be paid 80% of their wages for hours they cannot work, but with employers having to contribute 10% in July and 20% in August and September.
- Support for the self-employed also extended until September, with the scheme being widened to make 600 000 more self-employed people eligible.
- The temporary £20 increase to Universal Credit, introduced in April last year and due to end on 31 March this year, to be extended to the end of September.
- Stamp duty holiday on house purchases in England and Northern Ireland, under which there is no tax liability on sales of less than £500 000, extended from the end of March to the end of June.
- An additional £1.65bn to support the UK’s vaccination rollout.
- VAT rate for hospitality firms to be maintained at the reduced 5% rate until the end of September and then raised to 12.5% (rather than 20%) for a further six months.
- A range of grants for the arts, sport, shops , other businesses and apprenticeships.
- Business rates holiday for hospitality firms in England extended from the end of March to the end of June and then with a discount of 66% until April 2022.
- 130% of investment costs can be offset against tax – a new tax ‘super-deduction’.
- No tax rises on alcohol, tobacco or fuel.
- New UK Infrastructure Bank to be set up in Leeds with £12bn in capital to support £40bn worth of public and private projects.
- Increased grants for devolved nations and grants for 45 English towns.
It has surprised many commentators that there was no announcement of greater investment in the NHS or more money for social care beyond the £3bn for the NHS and £1bn for social care announced in the November Spending Review. The NHS England budget will fall from £148bn in 2020/21 to £139bn in 2021/22.
Effects on borrowing and GDP
The net effect of these measures for the two financial years 2020 to 2022 is forecast by the Treasury to be an additional £37.5bn of government expenditure and a £27.3bn reduction in tax revenue (see Table 2.1 in Budget 2021). This takes the total support since the start of the pandemic to £352bn across the two years.
According to the OBR, this will result in public-sector borrowing being 16.9% of GDP in 2020/21 (the highest since the Second World War) and 10.3% of GDP in 2021/22. Public-sector debt will be 107.4% of GDP in 2021/22, rising to 109.7% in 2023/24 and then falling to 103.8% in 2025/26.
Faced with this big increase in borrowing, the Chancellor also announced some measures to raise tax revenue beginning in two years’ time when, hopefully, the economy will have grown. Indeed, the OBR forecasts that GDP will grow by 4.0% in 2021 and 7.3% in 2022, with the growth rate then settling at around 1.7% from 2023 onwards. He announced that:
- Corporation tax on company profits over £250 000 will rise from 19% to 25% in April 2023. Rates for profits under £50 000 will remain at the current rate of 19%, with the rate rising in stages as profits rise above £50 000.
- Personal income tax thresholds will be frozen from 2022/23 to 2025/26 at £12 570 for the basic 20% marginal rate and at £50 270 for the 40% marginal rate. This will increase the average tax rate as people’s nominal incomes rise.
The policy of a fiscal boost now and a fiscal tightening later might pose political difficulties for the government as this does not fit with the electoral cycle. Normally, politicians like to pursue tighter policies in the early years of the government only to loosen policy with various giveaways as the next election approaches. With Rishi Sunak’s policies, the opposite is the case, with fiscal policy being tightened as the 2024 election approaches.
Another issue is the high degree of uncertainty in the forecasts on which he is basing his policies. If there is another wave of the coronavirus with a new strain resistant to the vaccines or if the scarring effects of the lockdowns are greater, then growth could stall. Or if inflation begins to rise and the Bank of England feels it must raise interest rates, then this would suppress growth. With lower growth, the public-sector deficit would be higher and the government would be faced with the dilemma of whether it should raise taxes, cut government expenditure or accept higher borrowing.
What is more, there are likely to be huge pressures on the government to increase public spending, not cut it by £4bn per year in the medium term as he plans. As Paul Johnson of the IFS states:
In reality, there will be pressures from all sorts of directions. The NHS is perhaps the most obvious. Further top-ups seem near-inevitable. Catching up on lost learning in schools, dealing with the backlog in our courts system, supporting public transport providers, and fixing our system for social care funding would all require additional spending. The Chancellor’s medium-term spending plans simply look implausibly low.

Ten years ago, the financial crisis deepened and stock markets around the world plummeted. The trigger was the collapse of Lehman Brothers, the fourth-largest US investment bank. It filed for bankruptcy on September 15, 2008. This was not the first bank failure around that time. In 2007, Northern Rock in the UK (Aug/Sept 2007) had collapsed and so too had Bear Stearns in the USA (Mar 2008).
Initially there was some hope that the US government would bail out Lehmans. But when Congress rejected the Bank Bailout Bill on September 29, the US stock market fell sharply, with the Dow Jones falling by 7% the same day. This was mirrored in other countries: the FTSE 100 fell by 15%.
At the core of the problem was excessive lending by banks with too little capital. What is more, much of the capital was of poor quality. Many of the banks held securitised assets containing ‘sub-prime mortgage debt’. The assets, known as collateralised debt obligations (CDOs), were bundles of other assets, including mortgages. US homeowners had been lent money based on the assumption that their houses would increase in value. When house prices fell, homeowners were left in a position of negative equity – owing more than the value of their house. With many people forced to sell their houses, prices fell further. Mortgage debt held by banks could not be redeemed: it was ‘sub-prime’ or ‘toxic debt’.
Response to the crisis
The outcome of the financial crash was a series of bailouts of banks around the world. Banks cut back on lending and the world headed for a major recession.
Initially, the response of governments and central banks was to stimulate their economies through fiscal and monetary policies. Government spending was increased; taxes were cut; interest rates were cut to near zero. By 2010, the global economy seemed to be pulling out of recession.
However, the expansionary fiscal policy, plus the bailing out of banks, had led to large public-sector deficits and growing public-sector debt. Although a return of economic growth would help to increase revenues, many governments felt that the size of the public-sector deficits was too large to rely on economic growth.
As a result, many governments embarked on a period of austerity – tight fiscal policy, involving cutting government expenditure and raising taxes. Although this might slowly bring the deficit down, it slowed down growth and caused major hardships for people who relied on benefits and who saw their benefits cut. It also led to a cut in public services.
Expanding the economy was left to central banks, which kept monetary policy very loose. Rock-bottom interest rates were then accompanied by quantitative easing. This was the expansion of the money supply by central-bank purchases of assets, largely government bonds. A massive amount of extra liquidity was pumped into economies. But with confidence still low, much of this ended up in other asset purchases, such as stocks and shares, rather than being spent on goods and services. The effect was a limited stimulation of the economy, but a surge in stock market prices.
With wages rising slowly, or even falling in real terms, and with credit easy to obtain at record low interest rates, so consumer debt increased.
So have the lessons of the financial crash been learned? Would we ever have a repeat of 2007–9?
On the positive side, financial regulators are more aware of the dangers of under capitalisation. Banks’ capital requirements have increased, overseen by the Bank for International Settlements. Under its Basel II and then Basel III regulations (see link below), banks are required to hold much more capital (‘capital buffers’). Some countries’ regulators (normally the central bank), depending on their specific conditions, exceed these the Basel requirements.
But substantial risks remain and many of the lessons have not been learnt from the financial crisis and its aftermath.
There has been a large expansion of household debt, fuelled by low interest rates. This constrains central banks’ ability to raise interest rates without causing financial distress to people with large debts. It also makes it more likely that there will be a Minsky moment, when a trigger, such as a trade war (e.g. between the USA and China), causes banks to curb lending and consumers to rein in debt. This can then lead to a fall in aggregate demand and a recession.
Total debt of the private and public sectors now amounts to $164 trillion, or 225% of world GDP – 12 percentage points higher than in 2009.
China poses a considerable risk, as well as being a driver of global growth. China has very high levels of consumer debt and many of its banks are undercapitalised. It has already experienced one stock market crash. From mid-June 2015, there was a three-week fall in share prices, knocking about 30% off their value. Previously the Chinese stock market had soared, with many people borrowing to buy shares. But this was a classic bubble, with share prices reflecting exuberance, not economic fundamentals.
Although Chinese government purchases of shares and tighter regulation helped to stabilise the market, it is possible that there may be another crash, especially if the trade war with the USA escalates even further. The Chinese stock market has already lost 20% of its value this year.
Then there is the problem with shadow banking. This is the provision of loans by non-bank financial institutions, such as insurance companies or hedge funds. As the International Business Times article linked below states:
A mind-boggling study from the US last year, for example, found that the market share of shadow banking in residential mortgages had rocketed from 15% in 2007 to 38% in 2015. This also represents a staggering 75% of all loans to low-income borrowers and risky borrowers. China’s shadow banking is another major concern, amounting to US$15 trillion, or about 130% of GDP. Meanwhile, fears are mounting that many shadow banks around the world are relaxing their underwriting standards.
Another issue is whether emerging markets can sustain their continued growth, or whether troubles in the more vulnerable emerging-market economies could trigger contagion across the more exposed parts of the developing world and possibly across the whole global economy. The recent crises in Turkey and Argentina may be a portent of this.
Then there is a risk of a cyber-attack by a rogue government or criminals on key financial insitutions, such as central banks or major international banks. Despite investing large amounts of money in cyber-security, financial institutions worry about their vulnerability to an attack.
Any of these triggers could cause a crisis of confidence, which, in turn, could lead to a fall in stock markets, a fall in aggregate demand and a recession.
Finally there is the question of the deep and prolonged crisis in capitalism itself – a crisis that manifests itself, not in a sudden recession, but in a long-term stagnation of the living standards of the poor and ‘just about managing’. Average real weekly earnings in many countries today are still below those in 2008, before the crash. In Great Britain, real weekly earnings in July 2018 were still some 6% lower than in early 2008.

In his 2016 Autumn Statement, the new Chancellor of the Exchequer, Philip Hammond, announced that he was abandoning his predecessor’s target of achieving a budget surplus in 2019/20 and beyond. This was partly in recognition that tax revenues were likely to be down as economic growth forecasts were downgraded by the Office for Budget Responsibility. But it was partly to give himself more room to boost the economy in response to lower economic growth. In other words, he was moving from a strictly rules-based fiscal policy to one that is more interventionist.
Although he still has the broad target of reducing government borrowing over the longer term, this new flexibility allowed him to announce increased government spending on infrastructure.
The new approach is outlined in the updated version of the Charter for Budget
Responsibility, published alongside the Autumn Statement. The government’s fiscal mandate would now include the following:
||a target to reduce cyclically-adjusted public-sector net borrowing to below 2% of GDP by 2020/21;
||a target for public-sector net debt as a percentage of GDP to be falling in 2020/21.
It also states that:
In the event of a significant negative shock to the UK economy, the Treasury will review the appropriateness of the fiscal mandate and supplementary targets as a means of returning the public finances to balance as early as possible in the next Parliament.
In the Autumn Statement, the new approach to fiscal policy is summarised as follows:
This new fiscal framework ensures the public finances continue on the path to sustainability, while providing the flexibility needed to support the economy in the near term.
With his new found freedom, the Chancellor was able to announce spending increases, despite deteriorating public finances, of £36bn by 2021/22 (see Table 1 in the Autumn Statement).
Most of the additional expenditure will be on infrastructure. To facilitate this, the government will set up a new National Productivity Investment Fund (NPIF) to channel government spending to various infrastructure projects in the fields of housing, transport, telecoms and research and development. The NPIF will provide £23bn to such projects between 2017/18 and 2021/22.
But much of the additional flexibility in the new Fiscal Mandate will be to allow automatic fiscal stabilisers to operate. The OBR forecasts an increase in borrowing of £122bn over the 2017/18 to 2021/22 period compared with its forecasts made in March this year. Apart from the additional £23bn spending on infrastructure, most of the rest will be as a result of lower tax receipts from lower economic growth. This, in turn, is forecast to be the result of lower investment caused by Brexit uncertainties and lower real consumer spending because of the fall in the pound and the consequent rise in prices.
But rather than having to tighten fiscal policy to meet the previous borrowing target, the new Fiscal Mandate will permit this rise in borrowing. The lower tax payments will help to reduce the dampening effect on the economy.
So are we entering a new era of fiscal policy? Is the government now using discretionary fiscal policy to boost aggregate demand, while also attempting to increase productivity? Or is the relaxation of the Fiscal Mandate just a redrawing of the rules to give a bit more flexibility over the level of stimulus the government can give the economy?

- If the economy slows more than has been forecast and public-sector borrowing rises faster, does the Chancellor have any more discretion in giving a further fiscal boost to the economy?
- Does the adjustment of borrowing targets as the economic situation changes make such a policy a discretionary one rather than a rules-based one?
As the Chancellor of the Exchequer, Philip Hammond, delivers his first Autumn statement, both the Office for Budget Responsibility (OBR) and the National Institute for Economic and Social Research (NIESR) have published updated forecasts for government borrowing and government debt.
They show a rise in government borrowing compared with previous forecasts. The main reason for this is a likely slowdown in the rate of economic growth and hence in tax revenues, especially in 2017. Last March, the OBR forecast GDP growth of 2.2% for 2017; it has now revised this down to 1.4%.
This forecast slowdown is because of a likely decline in the growth of aggregate demand caused by a decline in investment as businesses become more cautious given the uncertainty about the UK’s relationships with the rest of the world post Brexit. There is also likely to be a slowdown in real consumer expenditure as inflation rises following the fall in the pound of around 15%.
But what might be more surprising is that the public finances are not forecast to deteriorate even further. The OBR forecasts that the deficit will increase by a total of £122bn to £216bn over the period from 2016/17 to 2020/21. The NIESR predicts that it will rise by only £50bn to £187bn – but this is before the additional infrastructure spending and other measures announced in the Autumn Statement.
One reason is looser monetary policy. Following the Brexit vote, the Bank of England cut Bank Rate from 0.5% to 0.25% and introduced further quantitative easing. This makes it cheaper to finance government borrowing. What is more, the additional holdings of bonds by the Bank mean that the Bank returns to the government much of the interest (coupon payments) that would otherwise have been paid to the private sector.
Then, depending on the nature of the UK’s post-Brexit relationships with the EU, there could be savings in contributions to the EU budget – but just how much, no-one knows at this stage.
Finally, it depends on just what effects the measures announced in the Autumn Statement will have on tax revenues and government spending. We will examine this in a separate blog.
But even though public-sector borrowing is likely to fall more slowly than before the Brexit vote, the trajectory is still downward. Indeed, the previous Chancellor, George Osborne, had set a target of achieving a public-sector surplus by 2019/20.
But, would eventually bringing the public finances into surplus be desirable? Apart from the dampening effect on aggregate demand, such a policy could lead to underinvestment in infrastructure and other public-sector capital. There is thus a strong argument for continuing to run a deficit on the public-sector capital account to fund public-sector investment – such investment will increase incomes and social wellbeing in the future. It makes sense for the government to borrow for investment, just as it makes sense for the private sector to do so.
