In light of the budget and spending review, we use a series of charts to take a deep dive into the key announcements, the Office for Budget Responsibility (OBR) forecasts, and what this means for UK plc in the upcoming years.


Budget policies

The chart above shows the impact on spending and revenue of 13 key policies announced in the Chancellor’s budget, as well as the continuation of measures aimed at dealing with covid, and additional spending due to inflationary pressure. The impact shown in the chart is up until the end of the current Parliament. As the first bar shows, spending around covid will still be prevalent through the rest of the current Parliament. The Health and Social Care levy is the main additional revenue stream for the government, but as it will be spent directly on the NHS, it will not help to ease pressure in other areas of spending. The Chancellor’s speech seemed skewed towards spending rather than generating revenue. This is evident in the analysis above, with several more spending commitments, duty freezes, and allowance uplifts than increases in taxation. One such policy, the 10th freeze in fuel duty, is set to slightly ease pressures on the cost of living but does come at a cost of over £3bn before the end of the Parliament. Combined, the Alcohol Duty reform and one year freeze should save the alcohol industry £1.3bn, which helps to explain why The Wine and Spirit Trade Association has heralded it as a “huge relief”.

Tax Revenue

Tax revenue

The analysis in the paragraph above may seem unusual when assessed against this tax revenue chart. Three factors help to explain the increase in tax revenue that is expected over time. Firstly, the Health and Social Care levy contributes significantly to national insurance contributions. In addition to this, it is estimated that improving economic growth and inflation will raise overall tax revenue by around £50bn per year, largely seen in improvements to income tax, corporation tax, and VAT receipts. Lastly, despite this budget being light on tax increases, the March budget was the reverse. In March, the Chancellor announced that corporation tax will rise to 25% in 2023 and the personal allowance will be frozen between 2022 and 2026. The combined effect of these three points can be seen in the chart above.

Public Finances

Public Finances

The public finances chart above helps to highlight the severe impact that covid has had, raising total spending and public sector net borrowing by around 13% of GDP. In addition to this, public sector net debt increased by around 15% of GDP. The OBR expects this to stabilise at around 98% of GDP over the 2 years, before beginning a downward trajectory in 2024. Public sector net borrowing is expected to fall below pre-pandemic levels by 2023.


The charts below each show OBR forecasts for GDP growth, CPI inflation, as well as the rate of unemployment. Green lines are forecasts from November 2020, blue lines are from March 2021, whilst the yellow lines are forecasts announced alongside yesterday’s budget and spending review (27/10/2021).

Each GDP forecast paints a similar picture, with a strong short term rebound in growth, before returning to a steady rate of around 1.5%. However, whilst March’s 2021 growth forecast was more pessimistic, the OBR now expects the UK economy to grow by almost 7% this year, as the March forecast overestimated the fall in output associated with the last lockdown. Despite this, the supply constraints that are currently being experienced are expected to slow the rate of growth relative to the OBR’s last forecast.

A strong rebound in demand combined with constraints to supply have altered the OBR’s forecasts for inflation over the coming years. It is expected to peak at 4% next year, before falling back to its target in the medium term. It is worth noting, however, that the OBR are also preparing for a scenario in which inflation peaks at 1% higher than the above forecast and falls back to the 2% target a year later than predicted.

Unemployment forecasts

The OBR’s unemployment forecast has become more optimistic over time, owing in large part to the rapid reopening of the economy since March. A record 1.1m vacancies were advertised in the three months to September. As such, they expect unemployment to fall to 4.3% in 2023, a year earlier than previously forecast, and remain at that level in the medium term.
