What it means

A government may commit to keeping day-to-day spending within a certain amount of income, or to having a chosen debt measure fall compared with the size of the economy by a stated date. These commitments are fiscal rules. Their details matter: “debt falling” may mean debt as a share of GDP, not fewer pounds of debt. Rules can be changed, and a forecast that a rule will be met is not proof that it has already been met. In the UK, the Office for Budget Responsibility assesses the government's plans against its stated targets.

Example

Imagine a made-up rule that debt must fall as a share of GDP in five years. It could be forecast to pass even if the cash amount of debt is higher, provided GDP grows faster over that period.

Why it matters

Rules shape budget debates, but the headline wording can hide which measure and deadline a target actually uses.
