TUC calls for overhaul of OBR amid concerns its growth forecasts suppress vital investment signals
Executive summary: On August 8, 2026, the TUC publicly called for Chancellor John Healey to order a 'root and branch' review of the OBR, citing concerns its forecasts downplay the economic benefits of investment. The OBR's forecasts influence UK fiscal policy; if perceived as overly conservative, they may justify underinvestment in infrastructure and public services, affecting long-term growth.
Who is involved: Trades Union Congress (TUC), Chancellor John Healey, Office for Budget Responsibility (OBR)
Likely next: Healey may respond by initiating a review or defending the OBR's independence; parliamentary committees could scrutinize the OBR's methodology.
The Trades Union Congress (TUC) is urging Chancellor John Healey to commission a comprehensive review of the Office for Budget Responsibility (OBR), arguing its economic forecasts systematically underestimate the positive impact of public investment. The TUC contends that overly cautious OBR projections have contributed to fiscal restraint that hinders growth-oriented spending. The move reflects broader tensions between fiscal watchdogs and pro-investment stakeholders over the UK's economic trajectory.
