The past decade or so has seen large-scale economic turbulence. As we saw in the blog Fiscal impulses, governments have responded with large fiscal interventions. The COVID-19 pandemic, for example, led to a positive fiscal impulse in the UK in 2020, as measured by the change in the structural primary balance, of over 12 per cent of national income.
The scale of these interventions has led to a significant increase in the public-sector debt-to-GDP ratio in many countries. The recent interest rates hikes arising from central banks responding to inflationary pressures have put additional pressure on the financial well-being of governments, not least on the financing of their debt. Here we discuss these pressures in the context of the ‘r – g’ rule of sustainable public debt.
Public-sector debt and borrowing
Chart 1 shows the path of UK public-sector net debt and net borrowing, as percentages of GDP, since 1990. Debt is a stock concept and is the result of accumulated flows of past borrowing. Net debt is simply gross debt less liquid financial assets, which mainly consist of foreign exchange reserves and cash deposits. Net borrowing is the headline measure of the sector’s deficit and is based on when expenditures and receipts (largely taxation) are recorded rather than when cash is actually paid or received. (Click here for a PowerPoint of Chart 1)
Chart 1 shows the impact of the fiscal interventions associated with the global financial crisis and the COVID-19 pandemic, when net borrowing rose to 10 per cent and 15 per cent of GDP respectively. The former contributed to the debt-to-GDP ratio rising from 35.6 per cent in 2007/8 to 81.6 per cent in 2014/15, while the pandemic and subsequent cost-of-living interventions contributed to the ratio rising from 85.2 per cent in 2019/20 to around 98 per cent in 2023/24.
Sustainability of the public finances
The ratcheting up of debt levels affects debt servicing costs and hence the budgetary position of government. Yet the recent increases in interest rates also raise the costs faced by governments in financing future deficits or refinancing existing debts that are due to mature. In addition, a continuation of the low economic growth that has beset the UK economy since the global financial crisis also has implications for the burden imposed on the public sector by its debts, and hence the sustainability of the public finances. After all, low growth has implications for spending commitments, and, of course, the flow of receipts.
The analysis therefore implies that the sustainability of public-sector debt is dependent on at least three factors: existing debt levels, the implied average interest rate facing the public sector on its debts, and the rate of economic growth. These three factors turn out to underpin a well-known rule relating to the fiscal arithmetic of public-sector debt. The rule is sometimes known as the ‘r – g’ rule (i.e. the interest rate minus the growth rate).
Underpinning the fiscal arithmetic that determines the path of public-sector debt is the concept of the ‘primary balance’. This is the difference between the sector’s receipts and its expenditures less its debt interest payments. A primary surplus (a positive primary balance) means that receipts exceed expenditures less debt interest payments, whereas a primary deficit (a negative primary balance) means that receipts fall short. The fiscal arithmetic necessary to prevent the debt-to-GDP ratio rising produces the following stable debt equation or ‘r – g’ rule:
On the left-hand side of the stable debt equation is the required primary surplus (PS) to GDP (Y) ratio. Moving to the right-hand side, the first term is the existing debt-to-GDP ratio (D/Y). The second term ‘r – g’, is the differential between the average implied interest rate the government pays on its debt and the growth rate of the economy. These terms can be expressed in either nominal or real terms as this does not affect the differential.
To illustrate the rule consider a country whose existing debt-to-GDP ratio is 1 (i.e. 100 per cent) and the ‘r – g’ differential is 0.02 (2 percentage points). In this scenario they would need to run a primary surplus to GDP ratio of 0.02 (i.e. 2 percent of GDP).
The ‘r – g‘ differential
The ‘r – g’ differential reflects macroeconomic and financial conditions. The fiscal arithmetic shows that these are important for the dynamics of public-sector debt. The fiscal arithmetic is straightforward when r = g as any primary deficit will cause the debt-to-GDP ratio to rise, while a primary surplus will cause the ratio to fall. The larger is g relative to r the more favourable are the conditions for the path of debt. Importantly, if the differential is negative (r < g), it is possible for the public sector to run a primary deficit, up to the amount that the stable debt equation permits.
Consider Charts 2 and 3 to understand how the ‘r – g’ differential has affected debt sustainability in the UK since 1990. Chart 2 plots the implied yield on 10-year government bonds, alongside the annual rate of nominal growth (click here for a PowerPoint). As John explains in his blog The bond roller coaster, the yield is calculated as the coupon rate that would have to be paid for the market price of a bond to equal its face value. Over the period, the average annual nominal growth rate was 4.5 per cent, while the implied interest rate was almost identical at 4.6 per cent. The average annual rate of CPI inflation over this period was 2.8 per cent.
Chart 3 plots the ‘r – g’ differential which is simply the difference between the two series in Chart 2, along with a 12-month rolling average of the differential to help show better the direction of the differential by smoothing out some of the short-term volatility (click here for a PowerPoint). The differential across the period is a mere 0.1 percentage points implying that macroeconomic and financial conditions have typically been neutral in supporting debt sustainability. However, this does mask some significant changes across the period.
We observe a general downward trend in the ‘r – g’ differential from 1990 up to the time of the global financial crisis. Indeed between 2003 and 2007 we observe a favourable negative differential which helps to support the sustainability of public debt and therefore the well-being of the public finances. This downward trend of the ‘r – g’ differential was interrupted by the financial crisis, driven by a significant contraction in economic activity. This led to a positive spike in the differential of over 7 percentage points.
Yet the negative differential resumed in 2010 and continued up to the pandemic. Again, this is indicative of the macroeconomic and financial environments being supportive of the public finances. It was, however, largely driven by low interest rates rather than by economic growth.
Consequently, the negative ‘r – g’ differential meant that the public sector could continue to run primary deficits during the 2010s, despite the now much higher debt-to-GDP ratio. Yet, weak growth was placing limits on this. Chart 4 indeed shows that primary deficits fell across the decade (click here for a PowerPoint).
The pandemic and beyond
The pandemic saw the ‘r – g’ differential again turn markedly positive, averaging 7 percentage points in the four quarters from Q2 of 2020. While the differential again turned negative, the debt-to-GDP ratio had also increased substantially because of large-scale fiscal interventions. This made the negative differential even more important for the sustainability of the public finances. The question is how long the negative differential can last.
Looking forward, the fiscal arithmetic is indeed uncertain and worryingly is likely to be less favourable. Interest rates have risen and, although inflationary pressures may be easing somewhat, interest rates are likely to remain much higher than during the past decade. Geopolitical tensions and global fragmentation pose future inflationary concerns and a further drag on growth.
As well as the short-term concerns over growth, there remain long-standing issues of low productivity which must be tackled if the growth of the UK economy’s potential output is to be raised. These concerns all point to the important ‘r – g’ differential become increasingly less negative, if not positive. If so the fiscal arithmetic could mean increasingly hard maths for policymakers.

During the pandemic, millions of people’s wages in the UK were paid by the government to prevent the closure of businesses and a surge in unemployment. The furlough scheme officially came to an end in September 2021. However, with the spread of the Omicron variant and the fear of further restrictions being put in place, there has been a call by many to re-introduce the furlough scheme.
The furlough scheme
The furlough scheme began when the government brought in, what was officially called the Coronavirus Job Retention Scheme (CJRS) in early 2020. This was when the pandemic first forced businesses across the country to close. The scheme worked by paying part of employees’ wages, preventing the need for businesses to make their staff redundant, therefore avoiding a rapid rise in unemployment along with the associated costs. It also avoided the financial and emotional costs of firing and then rehiring workers post pandemic. Under the scheme, furloughed workers received 80% of their wages, up to £2500 a month, if they couldn’t work because of the impact of coronavirus. Employees were able to maintain the security of employment and the payments helped furloughed workers pay their bills.
The scheme saw billions of pounds spent paying the wages of employees whose firms were forced to close temporarily. It could be argued that the expense of the scheme was a huge disadvantage. However, the alternative would have been for the government to pay unemployment-related benefits. Despite the furlough scheme being deemed necessary, it was not without its drawbacks for the structure of businesses. Rather than businesses adapting to changes in the economy and consumer demands, they could decide to claim the money and avoid the need to restructure. There was also concern about the length of the furlough scheme and the ability of businesses to bounce back post-pandemic.
Since the start of the scheme, the specifics of what was paid and who received it changed over time, especially once the economy started opening again. Initial steps were made to allow part-time return to work and the scheme started to wind down over the summer of 2021, with the government covering less of the wages and businesses covering more. From July, employers had to provide 10% of the wages of their furloughed staff, with the government paying the rest. This then increased to 20% in August with the CJRS coming to a complete end on 30 September 2021. At this point, there were around 1.6 million employees still receiving payment from the scheme.
Impact on Employment
With the end to the furlough scheme in September 2021, there were concerns that this would lead to a large number of redundancies. However, data indicate that has not happened and there is a record number of job vacancies. Official figures show that UK employment rose in October, confirming the strength of the labour market. The Office for National Statistics stated that the employment rate rose to 75.5% in the three months to October, up 0.2 percentage points on the previous quarter. This is believed to be driven by a rise in part-time work, which had dropped sharply during the pandemic. However, it is important to note that the strength in these numbers was prior to the emergence of the Omicron variant.
In November, the government had ruled out once again bankrolling people’s wages at enormous expense. However, the Chancellor is now under pressure to respond to the latest announcements around the ever-changing landscape of the pandemic. The fast-spreading mutation of the Covid-19 virus, Omicron, is posing a fresh threat to the economy.
On the 8 December, the Prime Minister announced new ‘Plan B’ Covid rules for England. As part of these new rules to limit the spread of Omicron, people are being asked to work from home again if possible and face masks are compulsory in most public places. Covid passes or a negative Covid test result are also needed to get into nightclubs and large venues.
Scotland and Wales have brought in further restrictions. Scotland’s First Minister, Nicola Sturgeon, has asked people to limit socialising to three households at a time in the run-up to Christmas. Shops and hospitality venues in Scotland must bring back physical distancing and screens. In Wales, nightclubs will close after 26 December and social distancing will be reintroduced in shops.
Although the hospitality industry and retail sector remain open, they are facing a slump in trade thanks to the new restrictions and worries among the general public. With the work-from-home guidance and advice from health officials that people should limit their social interactions, pubs and restaurants have seen widespread cancellations in the run-up to Christmas. Trade is suffering and these mass cancellations come at a time when these sectors were hoping for bumper trade after a dismal last couple of years.
In light of these concerns, ministers are now being urged to guarantee support in case businesses have to shut. Despite the indication that it would be highly unlikely that the UK would experience a full return to the restrictions seen at previous stages of the crisis, the International Monetary Fund has stated that the UK government should be drawing up contingency plans. The IMF has called for a mini-furlough scheme in the event that the Omicron variant forces the government to close parts of the economy. The idea is that the mini-furlough scheme would see a limited version of the multi-billion-pound job subsidy scheme being rolled out if firms are forced to close.
There are strong calls for there to be targeted support, which this mini-furlough scheme could offer. The Resolution Foundation argued in mid-December that a furlough scheme tied solely to the hospitality industry would help prevent job loses in an industry that is currently suffering once again. It calculated that the cost of a hospitality-only furlough scheme would be £1.4 billion a month if it were pitched at the original level of 80% of wage support. If a January to March sector-specific scheme were to be introduced it is estimated to cost around £5 billion, a small cost in comparison to £46 billion spent on furlough so far.
Any reintroduction of a furlough scheme would be a jolt for the government. This would mean a return to the 2020-style arguments around protecting livelihoods and businesses, a contrast to the recent messaging from the Treasury of restoring public finances. There is also concern about how this will all impact on current growth predictions and inflation concerns. The IMF expects the growth of the UK economy to be 6.8% in 2021 and 5% in 2022. However, the drawback from this is that the recovery would also be accompanied by rising inflation. It has been suggested, therefore, that interest rate increases from the Bank of England would be needed to keep inflation under control, while at the same time being not so great as to kill off growth.
It was widely expected that the Bank of England would again put off a rate hike in order to wait to see the economic impact of Plan B restrictions. However, on Thursday 16 December, interest rates were raised for the first time in more than three years. Despite the fears that Omicron could slow the economy by causing people to spend less, Bank Rate was raised from 0.1% to 0.25% . This came in the wake of data showing prices climbing at the fastest pace for 10 years.
Government finances would take another huge hit if the furlough scheme were revived. But a version of such a scheme is likely to be necessary to avert an unemployment crisis and the attendant costs.
However, in resisting further measures, the government has argued that it has already acted early to help control the virus’s spread by rapidly rolling out booster jabs, while avoiding unduly damaging economic and social restrictions.
The government also argues that some of the measures from the total £400 billion Covid support package since the start of the pandemic will continue to help businesses into Spring 2022. Such measures include government-backed loans for small- and medium-sized businesses until June 2022, a reduction in VAT from 20% to 12.5% until March 2022 and business rates relief for eligible retail, hospitality, and leisure businesses until March 2022. Talks are ongoing with hospitality and and other business organisations directly affected by Covid restrictions.
The British Chambers of Commerce has argued that current measures are not enough and has called for VAT on hospitality and tourism to be cut back to its emergency rate of 5% and for the 100% business rates relief for retailers to return. The CBI has also called for any unspent local authority grants to be spent now to help affected firms and that further help, including business rates relief, should be on the table if restrictions continue after the government’s 5 January review date. The IMF said that with strong policy support, the economy had proved resilient, but it stressed that a return of some of the measures that prevented mass unemployment and large-scale business failures might soon be needed.
Infections caused by the new Omicron variant are rising rapidly, doubling every two to three days. It is expected to become the dominant variant in the UK soon with health officials warning it may be the most significant threat since the start of the pandemic. However, it is not yet known what the full extent of the impact of this new variant on the NHS will be, leaving the severity of future restrictions uncertain.
But what is evident is that the course of the pandemic has changed and there is a growing case for the government to start planning for new support packages. Although a reintroduction of the furlough scheme was hoped not to be needed on the path out of the pandemic, a short detour may be required in the form of a mini-furlough scheme. The size and reach of any support put in place will depend upon any further restrictions on economic activity.
- Should the level of support for business return to the levels in place earlier in 2021?
- What measures could a government put in place to curtail the spread of the Omicron variant that have only a minimal impact on business and employment?
- Compare the UK measures to curtail the spread of the virus with those used in some other European countries.
- What are the arguments for and against (a) re-introducing the furlough scheme as it was earlier in 2021; (b) introducing a version restricted to the hospitality sector?
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.

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?

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.
