What does the Chancellor do?
The Chancellor of the Exchequer runs HM Treasury, the government department that controls the public finances. If the Prime Minister sets the direction of the government, the Chancellor decides how it is paid for. The Chancellor lives at No. 11 Downing Street and holds the formal title of Second Lord of the Treasury (the Prime Minister is First Lord).
💷 Sets fiscal policy
Decides the level and structure of taxation and the overall total of government spending — the main tools of fiscal policy.
📕 Delivers the Budget
The main annual “fiscal event”, now held in the autumn. Tax changes are made law through a Finance Bill voted on by Parliament.
🏛️ Runs the Spending Review
Allocates multi-year budgets to each department (health, schools, defence), known as Departmental Expenditure Limits.
📏 Sets the fiscal rules
Self-imposed targets for borrowing and debt, written into the Charter for Budget Responsibility and approved by Parliament.
🏦 Writes the Bank’s remit
Sets the Bank of England’s inflation target (2% CPI) each year — but does not set interest rates. That job belongs to the independent Monetary Policy Committee.
📈 Manages government debt
Oversees borrowing through the sale of gilts (government bonds) by the Debt Management Office, and the stability of the financial system.
Meet the Chancellor: John Healey
- Appointed Chancellor on 20 July 2026 by new Prime Minister Andy Burnham.
- Previously Defence Secretary from the 2024 general election until June 2026 — unusual preparation for the Treasury.
- MP since 1997 (now Rawmarsh and Conisbrough, South Yorkshire), and a junior Treasury minister in 2005–07.
- Pledged to stick to the fiscal rules inherited from his predecessor, Rachel Reeves.
- Billed his Budget as giving households “breathing space today”.
Tell me why… a new Chancellor might want to keep his predecessor’s fiscal rules, even if he disliked them.
Tell me why… the Chancellor does not set interest rates.
Budget Day in six steps
- The forecastThe independent Office for Budget Responsibility (OBR) prepares its economic and fiscal forecast, and scores the cost of each Treasury policy.
- The red boxThe Chancellor poses outside No. 11 holding the red despatch box containing the speech — a tradition dating back to Gladstone in the 1800s.
- The statementAfter Prime Minister’s Questions, the Chancellor delivers the Budget speech to the House of Commons, usually lasting about an hour.
- The replyBy convention, the Leader of the Opposition (not the shadow chancellor) responds immediately.
- The documentsThe Treasury publishes the Budget “Red Book”, and the OBR publishes its Economic and Fiscal Outlook with its verdict on the fiscal rules.
- The lawMPs vote on Budget resolutions; the tax measures then pass through Parliament in the Finance Bill.
Who does what? Treasury, Bank and OBR
| Institution | Main job | Policy tools | Independent of government? |
|---|---|---|---|
| HM Treasury (Chancellor) | Manage the public finances; promote growth | Fiscal policy (tax, spending, borrowing); supply-side policy | No — part of government |
| Bank of England (MPC) | Price stability: hit the 2% CPI target | Monetary policy: Bank Rate, quantitative easing/tightening | Yes — operationally independent since 1997 |
| Office for Budget Responsibility | Forecast the economy and public finances; judge the fiscal rules | None — it advises and scrutinises | Yes — created in 2010 |
Tell me why… the OBR exists at all.
The Chancellor’s problem
Healey had very little room for manoeuvre. Three pressures squeezed him at once:
🌍 An external shock
Market turmoil and higher energy prices caused by the Iran war hit the UK economy and pushed up inflation and borrowing costs.
📉 Rising debt interest
Healey said financial market movements added £14bn to government borrowing costs this year. The government now spends about £1 in every £13 on debt interest.
🔒 Political locks
Labour’s manifesto ruled out raising the rates of income tax, employee National Insurance or VAT — the three biggest taxes.
The squeeze on “headroom”
Headroom against the “stability rule” (current budget in balance) in 2029-30. The Chancellor rounded £14.5bn to £15bn. Sources: OBR March and October 2026 forecasts; IFS and Resolution Foundation pre-Budget estimates.
Tell me why… higher gilt yields shrink the Chancellor’s headroom.
Tell me why… the think tanks warned against a “steady as she goes” Budget.
Key concepts for this Budget
Decision-by-decision analysis
Each card sets out what was announced, the analysis (the chain of reasoning economists would use), and the evaluation (what the outcome depends on). Finish each card by writing your own judgement.
Winners and losers
Every Budget redistributes. For each group, decide: winner, loser or it depends. Then reveal the suggested verdicts and argue with them.
Overall: progressive or regressive?
A Budget is progressive if it takes a larger share of income from the better-off, and regressive if it hits poorer households hardest. On the measures above, this Budget leans progressive: the main tax rises fall on savings, property, banks and wealthier business sellers, while the giveaways target lower-band council taxpayers, the low-paid, pensioners and small firms.
Tell me why… a Budget can look progressive on paper but feel different in practice.
Be the Chancellor
Your mission
You inherit Healey’s problem. After the energy shock and rising gilt yields, the OBR’s pre-Budget forecast leaves you headroom of just £12.5bn in 2029-30 — the year the stability rule is tested. Build a Budget that:
- keeps headroom above £10bn — below that, gilt markets get nervous and borrowing costs rise;
- never breaks the stability rule (headroom below £0);
- does the best you can for growth, inflation, fairness, public services and political trust.
Tick the policies you want. Watch the dashboard. Then press Deliver your Budget and compare your choices with Healey’s.
Healey’s real measures are calibrated roughly to the OBR’s costings for 2029-30; other options are illustrative. Watch out: temporary measures that end before 2029-30 do not change headroom at all. Scores are judgements, designed to provoke debate.

After the simulation
Tell me why… raising the basic rate of income tax by 1p would have been the “economist’s choice” but not the politician’s.
Tell me why… the bank surcharge and the £100 rebate do not change headroom at all.
Tell me why… capital investment barely dents headroom in the game.
The OBR verdict
The OBR’s October 2026 Economic and fiscal outlook is its first forecast to fully reflect the Iran war: its March forecast was finalised just before the conflict began. Higher energy prices are a negative terms-of-trade shock for the UK, a net energy importer — pushing inflation up and real incomes down.
Source: Office for Budget Responsibility, Economic and fiscal outlook – October 2026 (executive summary, Tables 2.1, 7.1, A.1, A.9). The 83% debt figure quoted in the speech is public sector net financial liabilities (PSNFL), the measure used for the investment rule — not headline net debt.
Chart 1: Inflation — what the war did to the forecast
CPI inflation, annual average, %. March 2026 vs October 2026 OBR forecasts. Source: OBR.
Tell me why… the OBR expects inflation to fall back quickly this time, unlike in 2022.
Chart 2: Growth — a dip, then recovery
Real GDP growth, %. Bars: October 2026 forecast (2025 is outturn). Dots: March 2026 forecast for 2026 and 2027. Source: OBR.
Tell me why… growth holds up in 2026 but slows in 2027.
Chart 3: Loosen now, tighten later
Direct effect of Budget policy decisions on borrowing, £bn. Positive = more borrowing (loosening). Source: OBR, Table 3.1.
Averaged over five years, the OBR calls the package broadly neutral (about £1.3bn a year). But the profile matters: support and spending come now, while tax rises and spending restraint arrive later — including a £5.5bn cut to day-to-day spending pencilled in for 2031-32.
Tell me why… economists are sceptical of “backloaded” plans.
Chart 4: A record tax burden
National Accounts taxes as % of GDP. The vertical axis starts at 34% to show the change clearly. Source: OBR, Table A.9.
Tell me why… the tax burden keeps rising even though no major tax rates went up.
Chart 5: Borrowing falls — slowly
Public sector net borrowing, % of GDP, 2025-26 (outturn) to 2031-32. Source: OBR, Table A.9.
Tell me why… higher inflation shrinks headroom even though it raises tax revenue.
Judging the Budget against the OBR
Are the fiscal rules met?
How much of the squeeze was forced, and how much was chosen?
How solid is the £14.5bn?
Is the Budget a real-terms pay rise for the low-paid?
What the analysts say: KPMG
The overall verdict
Chief economist Yael Selfin called it a cautious Budget that leaves difficult choices for later, noting “there are questions over how durable this approach will prove.” She judged headroom low by historical standards, with most of the fall driven by higher gilt yields.
On the banks
Peter Grant, KPMG’s banking tax lead, called the surcharge modest but warned it could reduce lending capacity, hitting mid-sized and specialist banks hardest because they have fewer ways to absorb the cost.
On consumers and retail
Linda Ellett, head of consumer, retail and leisure, welcomed the cost-of-living and rates help but expects consumer spending to stay under pressure into 2027, with shoppers waiting for discounts.
Tell me why… a thin buffer can force “fine-tuning” at the next Budget.
