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.

In his blog, The bond roller coaster, John looks at the pricing of government bonds and details how, in recent times, governments wishing to borrow by issuing new bonds are having to offer higher coupon rates to attract investors. The interest rate hikes by central banks in response to global-wide inflationary pressures have therefore spilt over into bond markets. Though this evidences the ‘pass through’ of central bank interest rate increases to the general structure of interest rates, it does, however, pose significant costs for governments as they seek to finance future budgetary deficits or refinance existing debts coming up to maturity.
The Autumn Statement in the UK is scheduled to be made on 22 November. This, as well as providing an update on the economy and the public finances, is likely to include a number of fiscal proposals. It is thus timely to remind ourselves of the size of recent discretionary fiscal measures and their potential impact on the sustainability of the public finances. In this first of two blogs, we consider the former: the magnitude of recent discretionary fiscal policy changes.
First, it is important to define what we mean by discretionary fiscal policy. It refers to deliberate changes in government spending or taxation. This needs to be distinguished from the concept of automatic stabilisers, which relate to those parts of government budgets that automatically result in an increase (decrease) of spending or a decrease (increase) in tax payments when the economy slows (quickens).
The suitability of discretionary fiscal policy measures depends on the objectives they trying to fulfil. Discretionary measures can be implemented, for example, to affect levels of public-service provision, the distribution of income, levels of aggregate demand or to affect longer-term growth of aggregate supply. As we shall see in this blog, some of the large recent interventions have been conducted primarily to support and stabilise economic activity in the face of heightened economic volatility.
Discretionary fiscal measures in the UK are usually announced in annual Budget statements in the House of Commons. These are normally in March, but discretionary fiscal changes can be made in the Autumn Statement too. The Autumn Statement of October 2022, for example, took on significant importance as the new Chancellor of the Exchequer, Jeremy Hunt, tried to present a ‘safe pair hands’ following the fallout and market turbulence in response to the fiscal statement by the former Chancellor, Kwasi Kwarteng, on 23 September that year.
The fiscal impulse
The large-scale economic turbulence of recent years associated first with the global financial crisis of 2007–9 and then with the COVID-19 pandemic and the cost-of-living crisis, has seen governments respond with significant discretionary fiscal measures. During the COVID-19 pandemic, examples of fiscal interventions in the UK included the COVID-19 Business Interruption Loan Scheme (CBILS), grants for retail, hospitality and leisure businesses, the COVID-19 Job Retention Scheme (better known as the furlough scheme) and the Self-Employed Income Support Scheme.
The size of discretionary fiscal interventions can be measured by the fiscal impulse. This captures the magnitude of change in discretionary fiscal policy and thus the size of the stimulus. The concept is not to be confused with fiscal multipliers, which measure the impact of fiscal changes on economic outcomes, such as real national income and employment.
By measuring fiscal impulses, we can analyse the extent to which a country’s fiscal stance has tightened, loosened, or remained unchanged. In other words, we are attempting to capture discretionary fiscal policy changes that result in structural changes in the government budget and, therefore, in structural changes in spending and/or taxation.
To measure structural changes in the public-sector’s budgetary position, we calculate changes in structural budget balances.
A budget balance is simply the difference between receipts (largely taxation) and spending. A budget surplus occurs when receipts are greater than spending, while a deficit (sometimes referred to as net borrowing) occurs if spending is greater than receipts.
A structural budget balance cyclically-adjusts receipts and spending and hence adjusts for the position of the economy in the business cycle. In doing so, it has the effect of adjusting both receipts and spending for the effect of automatic stabilisers. Another way of thinking about this is to ask what the balance between receipts and spending would be if the economy were operating at its potential output. A deterioration in a structural budget balance infers a rise in the structural deficit or fall in the structural surplus. This indicates a loosening of the fiscal stance. An improvement in the structural budget balance, by contrast, indicates a tightening.
The size of UK fiscal impulses
A frequently-used measure of the fiscal impulse involves the change in the cyclically-adjusted public-sector primary deficit.
A primary deficit captures the extent to which the receipts of the public sector fall short of its spending, excluding its spending on debt interest payments. It essentially captures whether the public sector is able to afford its ‘new’ fiscal choices from its receipts; it excludes debt-servicing costs, which can be thought of as reflecting fiscal choices of the past. By using a cyclically-adjusted primary deficit we are able to isolate more accurately the size of discretionary policy changes. Chart 1 shows the UK’s actual and cyclically-adjusted primary deficit as a share of GDP since 1975, which have averaged 1.3 and 1.1 per cent of GDP respectively. (Click here for a PowerPoint of the chart.)
The size of the fiscal impulse is measured by the year-on-year percentage point change in the cyclically-adjusted public-sector primary deficit as a percentage of potential GDP. A larger deficit or a smaller surplus indicates a fiscal loosening (a positive fiscal impulse), while a smaller deficit or a larger surplus indicates a fiscal tightening (a negative fiscal impulse).
Chart 2 shows the magnitude of UK fiscal impulses since 1980. It captures very starkly the extent of the loosening of the fiscal stance in 2020 in response to the COVID-19 pandemic. (Click here for a PowerPoint of the chart.) In 2020 the cyclically-adjusted primary deficit to potential output ratio rose from 1.67 to 14.04 per cent. This represents a positive fiscal impulse of 12.4 per cent of GDP.
A tightening of fiscal policy followed the waning of the pandemic. 2021 saw a negative fiscal impulse of 10.1 per cent of GDP. Subsequent tightening was tempered by policy measures to limit the impact on the private sector of the cost-of-living crisis, including the Energy Price Guarantee and Energy Bills Support Scheme.
In comparison, the fiscal response to the global financial crisis led to a cumulative increase in the cyclically-adjusted primary deficit to potential GDP ratio from 2007 to 2009 of 5.0 percentage points. Hence, the financial crisis saw a positive fiscal impulse of 5 per cent of GDP. While smaller in comparison to the discretionary fiscal responses to the COVID-19 pandemic, it was, nonetheless, a sizeable loosening of the fiscal stance.
Sustainability and well-being of the public finances
The recent fiscal interventions have implications for the financial well-being of the public-sector. Not least, the financing of the positive fiscal impulses has led to a substantial growth in the accumulated size of the public-sector debt stock. At the end of 2006/7 the public-sector net debt stock was 35 per cent of GDP; at the end of the current financial year, 2023/24, it is expected to be 103 per cent.
As we saw at the outset, in an environment of rising interest rates, the increase in the public-sector debt to GDP ratio creates significant additional costs for government, a situation that is made more difficult for government not only by the current flatlining of economic activity, but by the low underlying rate of economic growth seen since the financial crisis. The combination of higher interest rates and lower economic growth has adverse implications for the sustainability of the public finances and the ability of the public sector to absorb the effects of future economic crises.

To finance budget deficits, governments have to borrow. They can borrow short-term by issuing Treasury bills, typically for 1, 3 or 6 months. These do not earn interest and hence are sold at a discount below the face value. The rate of discount depends on supply and demand and will reflect short-term market rates of interest. Alternatively, governments can borrow long-term by issuing bonds. In the UK, these government securities are known as ‘gilts’ or ‘gilt-edged securities’. In the USA they are known as ‘treasury bonds’, ‘T-bonds’ or simply ‘treasuries’. In the EU, countries separately issue bonds but the European Commission also issues bonds.
In the UK, gilts are issued by the Debt Management Office on behalf of the Treasury. Although there are index-linked gilts, the largest proportion of gilts are conventional gilts. These pay a fixed sum of money per annum per £100 of face value. This is known as the ‘coupon payment’ and the rate is set at the time of issue. The ‘coupon rate’ is the payment per annum as a percentage of the bond’s face value:
Payments are made six-monthly. Each issue also has a maturity date, at which point the bonds will be redeemed at face value. For example, a 4½% Treasury Gilt 2028 bond has a coupon rate of 4½% and thus pays £4.50 per annum (£2.25 every six months) for each £100 of face value. The issue will be redeemed in June 2028 at face value. The issue was made in June 2023 and thus represented a 5-year bond. Gilts are issued for varying lengths of time from 2 to 55 years. At present, there are 61 different conventional issues of bonds, with maturity dates varying from January 2024 to October 2073.
Bond prices
Bonds can be sold on the secondary market (i.e. the stock market) before maturity. The market price, however, is unlikely to be the coupon price (i.e. the face value). The lower the coupon rate relative to current interest rates, the less valuable the bond will be. For example, if interest rates rise, and hence new bonds pay a higher coupon rate, the market price of existing bonds paying a lower coupon rate must fall. Thus bond prices vary inversely with interest rates.
The market price also depends on how close the bonds are to maturity. The closer the maturity date, the closer the market price of the bond will be to the face value.
Bond yields: current yield
A bond’s yield is the percentage return that a person buying the bond receives. If a newly issued bond is bought at the coupon price, its yield is the coupon rate.
However, if an existing bond is bought on the secondary market (the stock market), the yield must reflect the coupon payments relative to the purchase price, not the coupon price. We can distinguish between the ‘current yield’ and the ‘yield to maturity’.
The current yield is the coupon payment as a percentage of the current market price of the bond:
Assume a bond were originally issued at 2% (its coupon rate) and thus pays £2 per annum. In the meantime, however, assume that interest rates have risen and new bonds now have a coupon rate of 4%, paying £4 per annum for each £100 invested. To persuade people to buy old bonds with a coupon rate of 2%, their market prices must fall below their face value (their coupon price). If their price halved, then they would pay £2 for every £50 of their market price and hence their current yield would be 4% (£2/£50 × 100).
Bond yields: yield to maturity (YTM)
But the current yield does not give the true yield – it is only an approximation. The true yield must take into account not just the market price but also the maturity value and the length of time to maturity (and the frequency of payments too, which we will ignore here). The closer a bond is to its maturity date, the higher/lower will be the true yield if the price is below/above the coupon price: in other words, the closer will the market price be to the coupon price for any given market rate of interest.
A more accurate measure of a bond’s yield is thus the ‘yield to maturity’ (YTM). This is the interest rate which makes the present value of all a bond’s future cash flows equal to its current price. These cash flows include all coupon payments and the payment of the face value on maturity. But future cash flows must be discounted to take into account the fact that money received in the future is worth less than money received now, since money received now could then earn interest.
The yield to maturity is the internal rate of return (IRR) of the bond. This is the discount rate which makes the present value (PV) of all the bond’s future cash flows (including the maturity payment of the coupon price) equal to its current market price. For simplicity, we assume that coupon payments are made annually. The formula is the one where the bond’s current market price is given by:
Where: t is the year; n is the number of years to maturity; YTM is the yield to maturity.
Thus if a bond paid £5 each year and had a maturity value of £100 and if current interest rates were higher than 5%, giving a yield to maturity of 8%, then the bond price would be:
In other words, with a coupon rate of 5% and a higher YTM of 8%, the bond with a face value of £100 and five years to maturity would be worth only £88.02 today.
If you know the market price of a given bond, you can work out its YTM by substituting in the above formula. The following table gives examples.
The higher the YTM, the lower the market price of a bond. Since the YTM reflects in part current rates of interest, so the higher the rate of interest, the lower the market price of any given bond. Thus bond yields vary directly with interest rates and bond prices vary inversely. You can see this clearly from the table. You can also see that market bond prices converge on the face value as the maturity date approaches.
Recent activity in bond markets
Investing in government bonds is regarded as very safe. Coupon payments are guaranteed, as is repayment of the face value on the maturity date. For this reason, many pension funds hold a lot of government bonds issued by financially trustworthy governments. But in recent months, bond prices in the secondary market have fallen substantially as interest rates have risen. For those holding existing bonds, this means that their value has fallen. For governments wishing to borrow by issuing new bonds, the cost has risen as they have to offer a higher coupon rate to attract buyers. This make it more expensive to finance government debt.
The chart shows the yield on 10-year government bonds. It is calculated using the ‘par value’ approach. This gives the coupon rate that would have to be paid for the market price of a bond to equal its face value. Clearly, as interest rates rise, a bond would have to pay a higher coupon rate for this to happen. (This, of course, is only hypothetical to give an estimate of market rates, as coupon rates are fixed at the time of a bond’s issue.)
Par values reflect both yield to maturity and also expectations of future interest rates. The higher people expect future interest rates to be, the higher must par values be to reflect this.
In the years following the financial crisis of 2007–8 and the subsequent recession, and again during the COVID pandemic, central banks cut interest rates and supported this by quantitative easing. This involved central banks buying existing bonds on the secondary market and paying for them with newly created (electronic) money. This drove up bond prices and drove down yields (as the chart shows). This helped support the policy of low interest rates. This was a boon to governments, which were able to borrow cheaply.
This has all changed. With quantitative tightening replacing quantitative easing, central banks have been engaging in asset sales, thereby driving down bond prices and driving up yields. Again, this can be seen in the chart. This has helped to support a policy of higher interest rates.
Problems of higher bond yields/lower bond prices
Although lower bond prices and higher yields have supported a tighter monetary policy, which has been used to fight inflation, this has created problems.
First, it has increased the cost of financing government debt. In 2007/8, UK public-sector net debt was £567bn (35.6% of GDP). The Office for Budget Responsibility forecasts that it will be £2702bn (103.1% of GDP in the current financial year – 2023/24). Not only, therefore, are coupon rates higher for new government borrowing, but the level of borrowing is now a much higher proportion of GDP. In 2020/21, central government debt interest payments were 1.2% of GDP; by 2022/23, they were 4.4% (excluding interest on gilts held in the Bank of England, under the Asset Purchase Facility (quantitative easing)).
In the USA, there have been similar increases in government debt and debt interest payments. Debt has increased from $9tn in 2007 to $33.6tn today. Again, with higher interest rates, debt interest as a percentage of GDP has risen: from 1.5% of GDP in 2021 to a forecast 2.5% in 2023 and 3% in 2024. What is more, 31 per cent of US government bonds will mature next year and will need refinancing – at higher coupon rates.
There is a similar picture in other developed countries. Clearly, higher interest payments leave less government revenue for other purposes, such as health and education.
Second, many pension funds, banks and other investment companies hold large quantities of bonds. As their price falls, so this reduces the value of these companies’ assets and makes it harder to finance new purchases, or payments or loans to customers. However, the fact that new bonds pay higher interest rates means that when existing bond holdings mature, the money can be reinvested at higher rates.
Third, bonds are often used by companies as collateral against which to borrow and invest in new capital. As bond prices fall, this can hamper companies’ ability to invest, which will lead to lower economic growth.
Fourth, higher bond yields divert demand away from equities (shares). With equity markets falling back or at best ceasing to rise, this erodes the value of savings in equities and may make it harder for firms to finance investment through new issues.
At the core of all these problems is inflation and budget deficits. Central banks have responded by raising interest rates. This drives up bond yields and drives down bond prices. But bond prices and yields depend not just on current interest rates, but also on expectations about future interest rates. Expectations currently are that budget deficits will be slow to fall as governments seek to support their economies post-COVID. Also expectations are that inflation, even though it is falling, is not falling as fast as originally expected – a problem that could be exacerbated if global tensions increase as a result of the ongoing war in Ukraine, the Israel/Gaza war and possible increased tensions with China concerning disputes in the China Sea and over Taiwan. Greater risks drive up bond yields as investors demand a higher interest premium.

The Autumn Statement was announced by Jeremy Hunt in Parliament on Thursday 17th November. This was Hunt’s first big speech since becoming Chancellor or the Exchequer a few weeks ago. He revealed to the House of Commons that there will be tax rises and spending cuts worth billions of pounds, aimed at mending the nation’s finances. It is hoped that the new plans will restore market confidence shaken by his predecessor’s mini-Budget. He claimed that the mixture of tax rises and spending cuts would be distributed fairly.
What is the Autumn statement?
The March Budget is the government’s main financial plan, where it decides how much money people will be taxed and where that money will be spent. The Autumn Statement is like a second Budget. This is an update half a year later on how things are going. However, that doesn’t mean it is not as important. This year’s Autumn Statement is especially important given the number of changes in government in recent months. The Statement unfortunately comes at a time when the cost of living is rising at its fastest rate for 41 years, meaning that it is going to be a tough winter for many people.
Statement overview
It was expected that the Statement was not going to be one to celebrate, given that the UK is now believed to be in a recession. The Office for Budget Responsibility (OBR) forecasts that the UK economy will shrink by 1.4% next year. However, Hunt said that his focus was on stability and ensuring a shallower downturn. The Chancellor outlined his ‘plan for stability’ by announcing deep spending cuts and tax rises in the autumn statement. He said that half of his £55bn plan would come from tax rises, and the rest from spending cuts.
The Chancellor plans to tackle rising prices and restore the UK’s credibility with international markets. He said that it will be a balanced path to stability, with the need to tackle inflation to bring down the cost of living while also supporting the economy on a path to sustainable growth. It will mean further concerns for many, but the Chancellor argued that the most vulnerable in society are being protected. He stated that despite difficult decisions being made, the plan was fair.
What was announced?
The government’s overall strategy appears to assume that, by tightening fiscal policy, monetary policy will not have to tighten as much. The hopeful consequence of which is that interest rates will be lower than they otherwise would have been. This means interest-rate sensitive parts of the economy, the housing sector in particular, are more protected than it would have been.
The following are some of the key measures announced:
- Tax thresholds will be frozen until April 2028, meaning millions will pay more tax as their nominal incomes rise.
- Spending on public services in England will rise more slowly than planned – with some departments facing cuts after the next election.
- The state pensions triple lock will be kept, meaning pensioners will see a 10.1% rise in weekly payments.
- The household energy price cap per unit of gas and electricity has been extended for one year beyond April but made less generous, with typical bills then being £3000 a year instead of £2500.
- There will be additional cost-of-living payments for the ‘most vulnerable’, with £900 for those on benefits, and £300 for pensioners.
- The top 45% additional rate of income tax will be paid on earnings over £125 140 instead of £150 000.
- The UK minimum wage (or ‘National Living Wage’ as the government calls it) for people over 23 will increase from £9.50 to £10.42 per hour.
- The windfall tax on oil and gas firms will increase from 25% to 35%, raising £55bn over the period from now until 2028.
The public finances
A key feature of the Autumn Statement was the Chancellor’s attempt to tackle the deteriorating public finances and to reduce the public-sector deficit and debt. The following three charts are based on data from the OBR (see data links below). They all show data for financial years beginning in the year shown. They all include OBR forecasts up to 2025/26, with the forecasts being based on the measures announced in the Autumn Statement.
Figure 1 shows public-sector current expenditure and receipts and the balance between them, giving the current deficit (or surplus), shown by the green bars. Current expenditure excludes capital expenditure on things such as hospitals, schools and roads. Since 1973, there has been a current deficit in most years. However, the deficit of 11.5% of GDP in 2020/21 was exceptional given government support measures for households and business during the pandemic. The deficit fell to 3.3% in 2021/22, but is forecast to grow to 4.6% in 2022/23 thanks to government subsidies to energy suppliers to allow energy prices to be capped. (Click here for a PowerPoint of this chart.)
Figure 2 shows public-sector expenditure (current plus capital) from 1950. You can see the spike after the financial crisis of 2007–8 when the government introduced various measures to support the banking system. You can also see the bigger spike in 2020/21 when pandemic support measures saw government expenditure rise to a record 53.0% of GDP. It has risen again this financial year to a predicted to 47.3% of GDP from 44.7% last financial year. It is forecast to fall only slightly, to 47.2%, in 2023/24, before then falling more substantially as the tax rises and spending cuts announced in the Autumn Statement start to take effect. (Click here for a PowerPoint of this chart.)
Figure 3 shows public-sector debt since 1975. COVID support measures, capping energy prices and a slow growing or falling GDP have contributed to a rise in debt as a proportion of GDP since 2020/21. Debt is forecast to peak in 2023/24 at a record 106.7% of GDP. During the 20 years from 1988/89 to 2007/8 it averaged just 30.9% of GDP. After the financial crisis of 2007–8 it rose to 81.6% by 2014/15 and then averaged 82.2% between 2014/15 and 2019/20. (Click here for a PowerPoint of this chart.)
Criticism
The government has been keen to stress that Mr Hunt’s statement does not amount to a return to the austerity policies of the Conservative-Liberal Democrat coalition government, in office between 2010 and 2015. However, Labour Shadow Chancellor, Rachel Reeves, said Mr Hunt’s Autumn Statement was an ‘invoice for the economic carnage’ the Conservative government had created. There have also been some comments raised by economists questioning the need for spending cuts and tax rises on this scale, with some saying that the decisions being made are political.
Paul Johnson, the director of the Institute for Fiscal Studies has commented on the plans, stating that the British people ‘just got a lot poorer’ after a series of ‘economic own goals’ that have made a recovery much harder than it might have been. He went on to say that the government was ‘reaping the costs of a long-term failure to grow the economy’, along with an ageing population and high levels of historic borrowing.
Disapproval also came from Conservative MP, Jacob Rees-Mogg, who criticised the government’s tax increases. He raised concerns about the government’s plans to increase taxation when the economy is entering a recession. He said, ’You would normally expect there to be some fiscal support for an economy in recession.’
Economic Outlook
High inflation and rising interest rates will lead to consumers spending less, tipping the UK’s economy into a recession, which the OBR expects to last for just over a year. Its forecasts show that the economy will grow by 4.2% this year but will shrink by 1.4% in 2023, before growth slowly picks up again. GDP should then rise by 1.3% in 2024, 2.6% in 2025 and 2.7% in 2026.
The OBR predicts that there will be 3.2 million more people paying income tax between 2021/22 and 2027/28 as a result of the new tax policy and many more paying higher taxes as a proportion of their income. This is because they will be dragged into higher tax bands as thresholds and allowances on income tax, national insurance and inheritance tax have been frozen until 2028. Government documents said these decisions on personal taxes would raise an additional £3.5bn by 2028 – the consequence of ‘fiscal drag’ pulling more Britons into higher tax brackets. The OBR expects that there will be an extra 2.6 million paying tax at the higher, 40% rate. This is going to put more pressure on households who are already feeling the impact of inflation on their disposable income.
However, this pressure on incomes is set to continue, with real incomes falling by the largest amount since records began in 1956. Real household incomes are forecast to fall by 7% in the next few years, which even after the support from the government, is the equivalent of £1700 per year on average. And the number unemployed is expected to rise by more than 500 000. Senior research economist at the IFS, Xiaowei Xu, described the UK as heading for another lost decade of income growth.
There may be some good news for inflation, with suggestions that it has now peaked. The OBR forecasts that the inflation rate will drop to 7.4% next year. This is still a concern, however, given that the target set for inflation is 2%. Despite the inflation rate potentially peaking, the impact on households has not. The fall in the inflation rate does not mean that prices in the shops will be going down. It just means that they will be going up more slowly than now. The OBR expects that prices will not start to fall (inflation becoming negative) until late 2024.
Conclusion
The overall tone of the government’s announcements was no surprise and policies were largely expected by the markets, hence their muted response. However, this did not make them any less economically painful. There are major concerns for households over what they now face over the next few years, something that the government has not denied.
It has been suggested that this situation, however, has been made worse by historic choices, including cutting state capital spending, cuts in the budget for vocational education, Brexit and Kwasi Kwarteng’s mini-Budget. It is evident that Britons have a tough time ahead in the next year or so. The UK has already had one lost decade of flatlining living standards since the global financial crisis and is now heading for another one with the cost of living crisis.

In her bid to become Conservative party leader, Liz Truss promised to make achieving faster economic growth her number-one policy objective. This would involve pursuing market-orientated supply-side policies.
These policies would include lower taxes on individuals to encourage people to work harder and more efficiently, and lower taxes on business to encourage investment. The policy would also involve deregulation, which would again encourage investment, both domestic and inward investment from overseas. These proposals echoed the policies pursued in the 1980s by President Ronald Reagan in the USA and Margaret Thatcher in the UK.
On September 23, the new Chancellor, Kwasi Kwarteng, presented a ‘mini-Budget’ – although the size of the changes made it far from ‘mini’. This, as anticipated, included policies intended to boost growth, including scrapping the 45% top rate of income tax, which is currently paid by people earning over £150 000 (a policy withdrawn on 3 October after massive objections), cutting the basic rate of income tax from 20% to 19%, scrapping the planned rise in corporation tax from 19% to 25%, scrapping the planned rise in national insurance by 1.25 percentage points, a cut in the stamp duty on house purchase and scrapping the limit placed on bankers’ bonuses. In addition, he announced the introduction of an unlimited number of ‘investment zones’ which would have lower business taxes, streamlined planning rules and lower regulation. The policies would be funded largely from extra government borrowing.
Theoretically, the argument is simple. If people do work harder and firms do invest more, then potential GDP will rise – a rise in aggregate supply. This can be shown on an aggregate demand and supply diagram. If the policy works, the aggregate supply curve will shift to the right. Real GDP will rise and there will be downward pressure on prices. In Figure 1, real GDP will rise from Y0 to Y1 and the price level will fall from P0 to P1. However, things are not as simple as this. Indeed, there are two major problems.
The first concerns whether tax cuts will incentivise people to work harder. The second concerns what happens to aggregate demand. I addition to this, the policies are likely to have a profound effect on income distribution.
Tax cuts and incentives
Cutting the top rate of income tax would have immediately given people at the top of the income scale a rise in post-tax income. This would have created a substitution effect and an income effect. Each extra pound that such people earn would be worth more in post-tax income – 60p rather than 55p. This would provide an incentive for people to substitute work for leisure as work is now more rewarding. This is the substitution effect. On the other hand, with the windfall of extra income, they now would have needed to work less in order to maintain their post-tax income at its previous level. They may well indeed, therefore, have decided to work less and enjoy more leisure. This is the income effect.
With the diminishing marginal utility of income, generally the richer people are, the bigger will be the income effect and the smaller the substitution effect. Thus, cutting the top rate of income tax may well have led to richer people working less. There is no evidence that the substitution effect would be bigger.
If top rates of income tax are already at a very high level, then cutting then may well encourage more work. After all, there is little incentive to work more if the current rate of tax is over 90%, say. Cutting them to 80% could have a big effect. This was the point made by Art Laffer, one of Ronald Reagan’s advisors. He presented his arguments in terms of the now famous ‘Laffer curve’, shown in Figure 2. This shows the total tax revenue raised at different tax rates.
If the average tax rate were zero, no revenue would be raised. As the tax rate is raised above zero, tax revenues will increase. The curve will be upward sloping. Eventually, however, the curve will peak (at tax rate t1). Thereafter, tax rates become so high that the resulting fall in output more than offsets the rise in tax rate. When the tax rate reaches 100 per cent, the revenue will once more fall to zero, since no one will bother to work.
If the economy were currently to the right of t1, then cutting taxes would increase revenue as there would be a major substitution effect. However, most commentators argue that the UK economy is to the left of t1 and that cutting the top rate would reduce tax revenues. Analysis by the Office for Budget Responsibility in 2012 suggested that t1 for the top rate of income tax was at around 48% and that cutting the rate below that would reduce tax revenue. Clearly according to this analysis, 40% is considerably below t1.
As far as corporation tax is concerned, the 19% rate is the lowest in the G20 and yet the UK suffers from low rates of both domestic investment and inward direct investment. There is no evidence that raising it somewhat, as previously planned, will cut investment. And as far as individual entrepreneurs are concerned, cutting taxes is likely to have little effect on the desire to invest and expand businesses. The motivation of entrepreneurs is only partly to do with the money. A major motivation is the sense of achievement in building a successful business.
Creating investment zones with lower taxes, no business rates and lower regulations may encourage firms to set up there. But much of this could simply be diverted investment from elsewhere in the country, leaving overall investment little changed.
To assess these questions, the government needs to model the outcomes and draw on evidence from elsewhere. So far this does not seem to have happened. They government did not even present a forecast of the effects of its policies on the public finances, something that the OBR normally presents at Budget time. This was one of the reasons for the collapse in confidence of sterling and gilts (government bonds) in the days following the mini-Budget.
Effects on aggregate demand
Cutting taxes and financing them from borrowing will expand aggregate demand. In Figure 1, the AD curve will also shift to the right and this will push up prices. Inflation is already a serious problem in the economy and unfunded tax cuts will make it worse. Higher inflation will result in the Bank of England raising interest rates further to curb aggregate demand. But higher interest rates, by raising borrowing costs, are likely to reduce investment, which will have a negative supply-side effect.
The problem here is one of timing. Market-orientated supply-side policies, if they work to increase potential GDP, will take time – measured in years rather than months. The rise in aggregate demand will be much quicker and will thus precede the rise in supply. This could therefore effectively kill off the rise in supply as interest rates rise, the exchange rate falls and the economy is pushed towards recession. Indeed, the mini-Budget immediately sparked a run on the pound and the exchange rate fell.
The rising government debt may force the government to make cuts in public expenditure. Rather than cutting current expenditure on things such as nurses, teachers and benefits, it is easier to cut capital expenditure on things such as roads and other infrastructure. But this will have adverse supply-side effects.
Effects on income distribution
Those advocating market-orientated supply-side policies argue that, by making GDP bigger, everyone can gain. They prefer to focus on the size of the national ‘pie’ rather than its distribution. If the rich initially gain, the benefits will trickle down to the poorest in society. This trickle-down theory was popular in the 1980s with politicians such as Margaret Thatcher and Ronald Reagan and, more recently, with Republican presidents, such as Goerge W Bush and Donald Trump. There are two problems with this, however.
The first, which we have already seen, is whether such policies actually do increase the size of the ‘pie’.
The second is how much does trickle down. During the Thatcher years, income inequality in the UK grew, as it did in the USA under Ronald Reagan. According to an IMF study in 2015 (see the link to the IMF analysis below), policies that increase the income share of the poor and the middle class do increase growth, while those that raise the income share of the top 20 per cent result in lower growth.
After the mini-Budget was presented, the IMF criticised it for giving large untargeted tax cuts that would heighten inequality. The poor would gain little from the tax cuts. The changes to income tax and national insurance mean that someone earning £20 000 per year will gain just £167 per year, while someone earning £200 000 will gain £5220. What is more, the higher interest rates and higher prices resulting from the lower exchange rate are likely to wipe out the modest gains to the poor.
