The Guardian has published an interactive budget game that allows readers to step into the role of chancellor and attempt to produce a fiscal plan that satisfies competing pressures ahead of John Healey’s autumn statement on 28 October.
The exercise highlights three central and often conflicting objectives of any UK budget: finding the revenue to pay for public services, setting tax levels that will be acceptable to voters and members of parliament, and persuading the government’s creditors in the bond markets that the state can meet its obligations.
How the simulation works
Players are invited to make choices about spending, taxation and borrowing and then observe the simulated political and market responses. The game is designed to model the trade-offs that real chancellors face: policies that boost public spending can raise concerns about affordability, while tax increases risk voter and parliamentary backlash, and excessive borrowing can unsettle investors.
Why the tensions matter
Autumn budgets must balance immediate political calculations with longer-term financial credibility. Market confidence affects borrowing costs and the government’s ability to finance deficits; parliamentary support determines whether measures can be enacted; and public expectations shape the political feasibility of tax and spending decisions. The simulation underlines how difficult it can be to reconcile all three.
Readers can use the exercise as a way to test their own priorities and gain a clearer sense of the constraints confronting the chancellor when the formal budget is presented to parliament later this month.
