Tag: fiscal stance

In this blog we show how we can apply fiscal metrics to assess the UK government’s fiscal stance. This captures the extent to which fiscal policy contributes to the level of economic activity in the economy.

Changes in the fiscal stance can then be used to estimate the extent to which discretionary fiscal policy measures represent a tightening or loosening of policy. We can measure the size and direction of fiscal impulses arising from changes in the government’s budgetary position.

Such an analysis is timely given the Autumn Budget presented by Rachel Reeves on 30 October 2024. This was the first Labour budget in 14 years and the first ever to be presented by a female Chancellor of the Exchequer.

We conclude by considering the forecast profile of expenditures and revenues for the next few years and the new fiscal rules announced by the Chancellor.

The fiscal stance

At its most simple, the fiscal stance measures the extent to which fiscal policy increases or decreases demand, thereby influencing growth and inflation (see Box 1.F, page 28, Autumn Budget 2024: see link below).

The fiscal stance is commonly estimated by measures of pubic-sector borrowing. To understand this, we can refer to the circular flow of income model. In this model, excesses of government spending (an injection) over taxation receipts (a withdrawal or leakage) represent a net injection into the circular flow and hence positively affect the level of aggregate demand for national output, all other things being equal.

A commonly used measure of borrowing in assessing the fiscal stance of the is the primary deficit. Unlike public-sector net borrowing, which is simply the excess of the sector’s spending over its receipts (largely taxation), the primary deficit subtracts net interest costs. It therefore excludes the interest payments on outstanding public-sector debts (and interest income earned on financial assets). The primary deficit can therefore be written as public-sector borrowing less net interest payments.

As discussed in our blog Fiscal impulses in November 2023, the primary deficit captures whether the public sector is able to afford its present fiscal choices by abstracting from debt-serving costs that reflect past fiscal choices. In this way, the primary deficit is a preferable measure to net borrowing both in assessing the impact on economic activity, i.e. the fiscal stance, and in assessing whether today’s fiscal choices will require government to issue additional debt.

Chart 1 shows public-sector net borrowing and the primary balance as shares of GDP for the UK since financial year 1975/76 (click here for a PowerPoint). The data are from the latest Public Finances Databank published by the Office for Budget Responsibility, published on the day of the Autumn Budget in October (see Data links below).

Over the period 1975/6 to 2023/24, public-sector net borrowing and the primary deficit had averaged 3.8% and 1.3% of GDP respectively. In the financial year 2023/24, they were 4.5% and 1.5% (they had been as high as 15.1% and 14.1% in 2020/21 as a result of COVID support measures). In 2024/25 net borrowing and the primary deficit are forecast to be 4.5% and 1.6% respectively. By 2027/28, while net borrowing is forecast to be 2.3% of GDP, there is forecast to be a primary surplus of 0.7% of GDP.

The Autumn Budget lays out plans for higher tax revenues to contribute two-thirds of the overall reduction in the primary deficit over the forecast period (up to 2029/30), while spending decisions contribute the remaining third.

The largest tax-raising measure is an increase in the employer rate of National Insurance Contributions (NICs) by 1.2 percentage points to 15% from April 2025. This will be levied on employee wages above a Secondary Threshold of £5000, reduced from £9100, which will increase in line with CPI inflation each year from April 2028. (See John’s blog, Raising the minimum wage: its effects on poverty and employment, for an analysis on the effects of this change.) This measure, allowing for other changes to the operation of employer NICs, is expected to raise £122 billion over the forecast period. This amounts to over two-thirds of the additional tax take from the taxation measures taken in the Budget.

Chart 2 shows both net borrowing and the primary deficit after being cyclically-adjusted (click here for a PowerPoint). This process adjusts these fiscal indicators to account for those parts of spending and taxation that are affected by the position of the economy in the business cycle. These are those parts that act as automatic stabilisers helping, as the name suggests, to stabilise the economy.

The process of cyclical adjustment leads to estimates of receipts and expenditures as if the economy were operating at its potential output level and hence with no output gap. The act of cyclically adjusting the primary deficit, which is our preferred measure of the fiscal stance, allows us to assess better the public sector’s fiscal stance.

Over the period from 1975/6 up to and including 2023/24, the cyclically-adjusted primary deficit (CAPD) averaged 1.1% of potential GDP. In 2024/25 the CAPD is forecast to be 1.5% of potential GDP. It then moves to a surplus of 0.5% by 2027/28. It therefore mirrors the path of the unadjusted primary deficit.

Measuring the fiscal impulse

To assess even more clearly the extent to which the fiscal stance is changing, we can use the cyclically-adjusted primary deficit to measure a fiscal impulse. This captures the magnitude of change in discretionary fiscal policy.

The term should not be confused with fiscal multipliers which measure the impact of fiscal changes on outcomes, such as real GDP and employment. Instead, we are interested in the size of the impulse that the economy is being subject to. Specifically, we are measuring discretionary fiscal policy changes that result in structural changes in the government budget and which, therefore, allow an assessment of how much, if at all, a country’s fiscal stance has tightened or loosened.

The size of the fiscal impulse is measured by the year-on-year percentage point change in the cyclically-adjusted public-sector primary deficit (CAPD) as a percentage of potential GDP. A larger deficit or a smaller surplus indicates a fiscal loosening. This is consistent with a positive fiscal impulse. On the other hand, a smaller deficit or a larger surplus indicates a fiscal tightening. This is consistent with a negative fiscal impulse.

Chart 3 shows the magnitude of UK fiscal impulses since the mid-1970s (Click here for a PowerPoint file). The scale of the fiscal interventions in response to the COVID-19 pandemic, which included the COVID-19 Business Interruption Loan Scheme (CBILS) and Job Retention Scheme (‘furlough’), stand out sharply. In 2020 the CAPD to potential output ratio rose from 1.7 to 14.4%. This represents a positive fiscal impulse of 12.4% of GDP.

This was followed in 2021 by a tightening of the fiscal stance, with a negative fiscal impulse of 10.1% of GDP as the CAPD to potential output fell back to 4.0%. 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.

For comparison, the fiscal response to the global financial crisis from 2007 to 2009 saw a cumulative positive fiscal impulse of 5.6% of GDP. While smaller in comparison to the discretionary fiscal responses to the COVID-19 pandemic, it nonetheless represented a sizeable loosening of the fiscal stance.

Chart 4 focuses on the implied fiscal impulse for the forecast period up to 2029/30 (click here for a PowerPoint). The period is notable for a negative fiscal impulse each year. Across the period as a whole, this there is a cumulative negative fiscal impulse of 2.6% of GDP. Most of the ‘heavy-lifting’ of the fiscal consolidation occurs in the three financial years from 2025/26 during which there is a cumulative negative impulse of 2.0% of GDP.

Looking forward

To conclude, we consider the implications for the projected profiles of public-sector spending, receipts and liabilities over the forecast period up to 2029/30.

Chart 5 plots data since the mid-1950s (click here for a PowerPoint). It shows the size of total public-sector spending (also known as ‘total managed expenditures’), taxation receipts (sometimes referred as the ‘tax burden’) and total public-sector receipts as shares of GDP. This last one includes additional receipts, such as interest payments on financial assets and income generated by public corporations, as well as taxation receipts.

The OBR forecasts that in real terms (i.e. after adjustment for inflation), public-sector spending will increase on average over the period from 2025/26 to 2029/30 by 1.4% per year, but with total receipts due to rise more quickly at 2.5% per year and taxation receipts by 2.8% per year. The implications of this, as discussed in the OBR’s October 1014 Economic and Fiscal Outlook (see link below), are that:

the size of the state is forecast to settle at 44% of GDP by the end of the decade, almost 5 percentage points higher than before the pandemic” while additional tax revenues will “push the tax take to a historic high of 38% of GDP by 2029-30

Finally, the government has committed to two key rules: a stability rule and an investment rule.

The stability rule. This states that the current budget must be in surplus by 2029/30 or, once 2029/30 becomes the third year of the forecast period, it will be in balance or surplus every third year of the rolling forecast period thereafter. The current budget refers to the difference between receipts and expenditures other than capital expenditures. In effect, it captures the ability of government to meet day-to-day spending and is intended to ensure that over the medium term any borrowing is solely for investment. It is important to note that ‘balance’ is defined in a range of between a deficit and surplus of no more than 0.5% of GDP.

The stability rule replaces the borrowing rule of the previous government that public net borrowing, therefore inclusive of investment expenditures, was not to exceed 3% of GDP by the fifth year of the rolling forecast period.

The investment rule. The government is planning to increase investment. In order to do this in a financially sustainable way, the investment rule states that public-sector net financial liabilities (PSNFL) or net financial debt for short, is falling as a share GDP by 2029/30, until 2029/30 becomes the third year of the forecast period. PSNFL should then fall by the third year of the rolling forecast period. PSNFL is a broader measure of the sector’s balance sheet than public-sector net debt (PSND), which was targeted under the previous government and which was required to fall by the fifth year of the rolling forecast period.

The new target, as well as now extending to the Bank of England, ‘nets off’ not just liquid liabilities (i.e. cash in the bank and foreign exchange reserves) but also financial assets such as shares and money owed to it, including expected student loan repayments. While liabilities are broader too, including for example, the local government pension scheme, the impact is expected to reduce the new liabilities target by £236 billion or 8.2 percentage points of GDP in 2024/25. The hope is that both rules can support what the Budget Report labels a ‘step change in investment’.

As Chart 6 shows, public investment as a share of GDP has not exceeded 6% this century and during the 2010s averaged only 4.4% (click here for a PowerPoint). The forecast has it rising above 5% for a time, but easing to 4.8% by end of the period.

This suggests more progress will be needed if the UK is to experience a significant and enduring increase in public investment. Of course, this needs to be set in the context of the wider public finances and is illustrative of the choices facing fiscal policymakers across the globe after the often violent shocks that have rocked economies and impacted on the state of the public finances in recent years.

The following blog is inspired by my teaching of macroeconomic issues to my final year students at Aston University. In the classes we’ve been discussing important aspects of monetary and fiscal policy design. What has become clear to me and my students is that the trade-offs which characterise the discipline of economics are certainly alive and well in the current environment in which monetary and fiscal policy choices are being made.

To demonstrate this we consider here some of the discussions we’ve had in class around central bank independence and monetary policy mandates. We’ve also looked at fiscal policy. Here we’ve examined the state of the public finances and the importance that seems to be attached to debt stabilisation and the imposition of debt rules.

Delegation and central bank mandates

My teaching this term began by introducing my students to one of the most important and influential monetary policy models. This is the model of Kydland and Prescott. Their model, published in the Journal of Political Economy in 1977 has become the theoretical bedrock for the modern-day operational independence of central banks.1

The model explores how systemically high inflation can become established in economies when policymakers have the political incentive to lower unemployment or increase output above its long-run equilibrium value. This may be the case if governments operate monetary policy rather than the central bank (of if the central bank operates monetary policy but follows government objectives). By adopting expansionary monetary policy, governments can increase their popularity.

But this is likely to be short-lived, as any increased economic activity will only be temporary (assuming that the natural-rate hypothesis holds). Soon, inflation will rise.

But, if an election is on the horizon, there may be enough time to boost output and employment before inflation rises. In other words, an expectations-augmented Phillips curve may present governments with an incentive to loosen monetary policy and worry about the inflation consequences after the election.

However, the resulting ‘inflation surprise’ through the loosening of monetary policy means a fall in real pay and therefore in purchasing power. If people suspect that governments will be tempted to loosen policy, they will keep their expectations of inflation higher than the socially optimal inflation rate. Consequently, low-inflation targets lack credibility when governments have the temptation to loosen monetary policy. Such targets are time-inconsistent because governments have an incentive to renege and deliver higher inflation through a looser monetary policy. The result is an inflation bias.

Central bank independence
To prevent this inflationary bias arising, many central banks around the world have been given some form of operational independence with a mandate centred around an inflation-rate target. By delegating monetary policy to a more conservative central bank, the problem of inflationary bias can be addressed.

Yet central bank independence is not without its own issues and this has been an important part of the discussions with my students. Today, many economies are continuing to experience the effects of the inflationary shocks that began in 2021 (see Chart 1 for the UK CPI inflation rate: click here for a PowerPoint). The question is whether the appointment of a conservative or hard-nosed hawkish central banker trades off the stabilisation of inflation for greater volatility in output or unemployment.

The inflation–output stabilisation trade-off is closely associated with the works of Kenneth Rogoff2 and John Taylor3. The latter is known for his monetary policy rule, which has become known as the ‘Taylor rule’. This advocates that a rules-based central bank ought to place weight on both inflation and output stabilisation.

This is not without its own issues, however, since, by also placing weight on output stabilisation, we are again introducing the possibility of greater inflationary bias in policy making. Hence, while the act of delegation and a rules- or target-based approach may mitigate the extent of the bias relative to that in the Kydland and Prescott model, there nonetheless still remain issues around the design of the optimal framework for the conduct of monetary policy.

Indeed, the announcement that the UK had moved into recession in the last two quarters of 2023 can be seen as evidence that an otherwise abstract theoretical trade-off between inflation and output stabilisation is actually very real.

My classroom discussions have also shown how economic theory struggles to identify an optimal inflation-rate target. Beyond accepting that a low and stable inflation rate is desirable, it is difficult to address fully the student who asks what is so special about a 2% inflation target. Would not a 3% target, for example, be preferable, they might ask?

Whilst this may sound somewhat trivial, it has real-world consequences. In a world that now seems to be characterised by greater supply-side volatility and by more frequent inflation shocks than we were used to in recent history, might a higher inflation rate target be preferable? Certainly, one could argue that, with an inflation–output stabilisation trade-off, there is the possibility that monetary policy could be unduly restrictive in our potential new macroeconomic reality. Hence, we might come to see governments and central banks in the near future revisiting the mandates that frame the operation of their monetary policy. Time will tell.

Fiscal policy and debt stabilisation

The second topic area that I have been discussing in my final-year macroeconomics classes has centred around fiscal policy and the state of the public finances. The context for this is that we have seen a significant increase in public debt-to-GDP ratios over the past couple of decades as the public sector has attempted to absorb significant economic shocks. These include the global financial crisis of 2007–8, the COVID-19 pandemic and the cost-of-living crisis. These interventions in the case of the UK have seen its public debt-to-GDP ratio more than triple since the early 2000s to close to 100% (see Chart 2: click here for a PowerPoint).

Understandably, given the stresses placed on the public finances, economists have increasingly debated issues around debt sustainability. These debates have been mirrored by politicians and policymakers. A key question is whether to have a public debt rule. The UK has in recent years adopted such a rule. The arguments for a rule centre on ensuring sound public finances and maintaining the confidence of investors to purchases public debt. A debt rule therefore places a discipline on fiscal policy, with implications for taxation and spending.

How easy it is to stick to a debt rule depends on three key factors. It will be harder to stick to the rule:

  • The higher the current debt-to-GDP ratio and hence the more it needs to be reduced to meet the rule.
  • The higher the rate of interest and hence the greater the cost of servicing the public debt.
  • The lower the rate of economic growth and hence the less quickly will tax revenues rise.

With a given debt-to-GDP ratio, a given average interest rate payable on its debt, and a given rate of economic growth, we can determine the primary fiscal balance relative to GDP a government would need to meet for the debt-to-GDP ratio to remain stable. This is known as the ‘debt-stabilising primary balance’. The primary balance is the difference between a government’s receipts and its expenditures less the interest payments on its debt.

This fiscal arithmetic is important in determining a government’s fiscal choices. It shows the implications for spending and taxation. These implications become ever more important and impactful on people, businesses, and society when the fiscal arithmetic becomes less favourable. This is a situation that appears to be increasingly the case for many countries, including the UK, as the rate of interest on public debt rises relative to a country’s rate of economic growth. As this happens, governments are increasingly required to run healthier primary balances. This of course implies a tightening of their fiscal stance.

Hence, the fiscal conversations with my students have focused on both the benefits and the costs of debt-stabilisation. In respect of the costs, a few issues have arisen.

First, as with the inflation-rate target, it is hard to identify an optimal public debt-to-GDP ratio number. While the fiscal arithmetic may offer some clue, it is not straightforward to address the question as to whether a debt-to-GDP ratio of say 100% or 120% would be excessive for the UK.

Second, it is possible that the debt stabilisation itself can make the fiscal arithmetic of debt stabilisation more difficult. This occurs if fiscal consolidation itself hinders long-term economic growth, which then makes the fiscal arithmetic more difficult. This again points to the difficulties in designing policy frameworks, whether they be for monetary or fiscal policy.

Third, a focus on debt stabilisation alone ignores the fact that there are two sides to any sector’s balance sheet. It would be very unusual when assessing the well-being of businesses or households if we were to ignore the asset side of their balance sheet. Yet, this is precisely the danger of focusing on public debt at the exclusion of what fiscal choices can mean for public-sector assets, from which we all can potentially benefit. Hence, some would suggest a more balanced approach to assessing the soundness of the public finances might involve a net worth (assets less liabilities) measure. This has parallels with the debates around whether mandates of central banks should be broader.

Applications in macroeconomics

What my teaching of a topics-based macroeconomics module this term has vividly demonstrated is that concepts, theories, and models come alive, and are capable of being understood better, when they are used to shine a light on real-world issues. The light being shone on monetary and fiscal policy in today’s turbulent macroeconomic environment is perhaps understandably very bright.

Indeed, the light being shone on fiscal policy in the UK and some other countries facing an upcoming election, is intensified further with the state of the public finances shaping much of the public discourse on fiscal choices. Hopefully, my students will continue to debate these important issues beyond their graduation, stressing their importance for people’s lives and, in doing so, going beyond the abstract.

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.
