MPs defend UK budget watchdog against 'shooting the messenger' critics

The Treasury committee has rejected "siren calls to fundamentally reform" the Office for Budget Responsibility, declaring that attacks on the government's independent economic forecaster amount to "shooting the messenger".

In a report published on 23 September, the influential group of MPs pushed back against critics from both the left and the right of the political spectrum who have targeted the OBR in recent years.

The committee's intervention defends the institutional architecture of British fiscal scrutiny at a moment when that architecture faces pressure from multiple directions. Critics have questioned the watchdog's role whenever tight public finances force policymakers into difficult decisions.

The MPs reject that framing outright. In their view, the OBR should not shoulder blame when governments have to make tough choices because of constrained budgets. The numbers, not the forecaster, drive the pain.

The committee's stance amounts to a full-throated endorsement of the status quo. It declined to recommend structural overhaul of the watchdog's mandate, methods or independence, and instead treated the attacks themselves as the problem.

For markets and fiscal analysts, the report signals that parliamentary support for independent economic forecasting remains firm. The OBR, created to provide independent assessments of the UK's fiscal position, retains its institutional footing despite the political crossfire.

The timing matters. Public finances have dominated recent budget cycles, and every uncomfortable OBR assessment has carried direct consequences for tax and spending decisions. That dynamic has made the forecaster a target for politicians seeking to shift responsibility for austerity-adjacent choices.

The Treasury committee's message to those politicians is blunt: the messenger is not the cause of the message. Its report closes off, for now, the most serious parliamentary avenue for weakening or restructuring the watchdog, leaving critics of UK fiscal forecasting without a legislative vehicle for fundamental change.
