This briefing answers some FAQs related to the government's budget deficit.
The budget deficit: a short guide (158 KB , PDF)
When the government spends more than it receives in tax and other revenues it borrows to cover the difference. This borrowing is known as ‘public sector net borrowing’ but is often referred to as the deficit.
In the financial year 2023/24, government revenue – from taxes and other receipts – was £1,096 billion (£1.1 trillion) while government spending was £1,217 billion (£1.2 trillion). The deficit was therefore £120 billion, equivalent to 4.4% of GDP.
At 4.4% of GDP, the deficit was the UK’s eighteenth largest since 1948.
Borrowing of £120 billion is equivalent to around £1,780 per head of the UK’s population.
It is not unusual for government to borrow. Since 1970/71, the government has had a surplus (spent less than it received in revenues) in only five years. The last budget surplus was in 2000/01.
Since 1970/71, the average annual budget deficit is 3.7% of GDP. It has varied significantly over this period as the chart below shows. Aside from 2020/21, large budget deficits occurred in the mid-1970s and early 1990s and more recently after the 2008-2009 financial crisis.
The UK had above an average budget deficit in 2022/23 and 2023/24. The UK faced high inflation, interest rates increased and its economy was growing relatively slowly. The Government spent a lot – particularly during 2022/23 – supporting households and businesses with high energy prices and other cost of living pressures. Meanwhile, government spending on debt interest was higher than in the recent past. The Library briefing Rising cost of living in the UK discusses the support government provided.
The deficit is forecast to fall to more typical levels in the years after 2023/24, on the back of a recovering economy and net tax rises and spending cuts announced since March 2021.
The deficit reached a peacetime record in 2020/21 of 15% of GDP, largely for two reasons:
Government spending increased from 39.6% of GDP in 2019/20 to 53.1% in 2020/21. The large increase reflects both government spending increasing in cash terms by around 25% and GDP falling by around 7%, in 2020/21.
While government revenues fell in cash terms, they became larger relative to the size of the economy. This was because GDP shrank more than revenues did. Government revenues were equivalent to 36.9% of GDP in 2019/20 and 38.0% of GDP in 2020/21.
The Government continued to support public services, households and businesses during 2021/22, but to a lesser extent than in the previous year. Government’s pandemic-related support cost around £78 billion in 2021/22, compared with £229 billion in 2020/21.
The Library briefing Coronavirus: Economic impact discusses the coronavirus pandemic’s effect on the budget deficit.
Governments across the world borrowed more due to the coronavirus pandemic. The International Monetary Fund (IMF) estimate that across advanced economies borrowing averaged 3.2% of GDP in 2022. For the G7 group of advanced economies borrowing averaged 4.1% of GDP.
The IMF report UK government borrowing of 4.7% of GDP in 2022. Amongst the G7 countries, Italy and France borrowed more than the UK, relative to the size of their economies. The IMF’s data for the UK may differ from figures reported by UK organisations – such as the ONS – but the IMF’s data are good for making international comparisons.
The budget deficit is financed by the sale of government bonds. These are essentially interest paying “IOUs” which the government sells to investors. Purchasers of government bonds include pension funds, insurance companies, households and overseas investors. The bonds make up most government debt. Once the bonds have been bought, they can be traded by investors on so-called secondary markets. The Library Insight Coronavirus: Government debt, an explainer explains this further.
Interest payments on government’s past borrowing are a relatively big cost for government. In 2023/24, government’s net debt interest spending was £102 billion, which is equivalent to 3.8% of GDP or 8.4% of government spending.
In the last two years the government spent more on debt interest than in the preceding years. This is largely because the interest paid on around one quarter of the government’s debt is linked to inflation, which accelerated during 2022/23. Interest rates also rose, further increasing spending on debt interest.
Government was spending relatively little, by historical standards, on debt interest until early-2021. The growth of spending on debt interest is explored further in section 2.5 of the Library briefing Spring Budget 2024: Background briefing.
The current budget deficit is the difference between government’s day-to-day spending and its revenues, or more formally its current spending and current receipts. Unlike the overall budget deficit, the current budget deficit doesn’t include investment spending and therefore is said to measure the degree to which taxpayers meet the cost of paying for the services provided to them.
The current budget deficit was £49 billion in 2023/24, equivalent to 1.8% of GDP.
A distinction is often drawn between the cyclical and structural elements of the budget deficit. The size of the deficit is influenced by the state of the economy: in a boom, when the economy is above its potential, tax receipts are relatively high and spending on work-related welfare is low. This reduces the level of borrowing. The reverse happens in a recession when borrowing tends to be high.
The structural deficit is that part of the deficit that is not related to the state of the economy. This part of the deficit will not disappear when the economy recovers. It thus gives a better guide to the underlying level of the deficit than the headline figure. However, the structural deficit cannot be directly measured so it must be estimated, which is difficult to do and open to interpretation.
The deficit is the difference between government revenue and spending, usually measured over a single financial year. Debt is the total amount owed by the Government which has accumulated over the years. Debt is therefore a much larger sum of money. At the end of 2023/24 public sector net debt was £2,690 billion (i.e. £2.6 trillion), or 98% of GDP. This is equivalent to around £37,900 per person in the UK.
Government’s borrowing during the coronavirus pandemic has meant that public sector debt has risen to a level last seen in the early 1960s, relative to the size of the economy. In the 1960s, government debt was still falling after reaching over 250% of GDP during World War II.
The Office for Budget Responsibility (OBR) has produced a brief guide to the public finances, which provides a brief introduction to the UK public finances and to the terms used to describe them in the official statistics.
In March 2016, the ONS produced a data driven explanation of the deficit and debt.
Those wishing to delve further into technical areas should look at the Office for National Statistics’ (ONS’) Public Sector Finances methodological guide. The ONS has also produced a public sector finances glossary.
Data on the deficit, debt, spending and receipts are available from the OBR’s public finances databank. Some of the series begin in 1900/01, and the data includes the latest forecasts.
The OBR’s historical public finances database contains 300 years of tax, spending, borrowing and debt data.
