Office for Budget Responsibility: Forecasts
The question
To ask the Chancellor of the Exchequer, when was she first informed by the Office for Budget Responsibility that they planned to review the Government's productivity forecasts.
Answered by Lucy Rigby
The OBR regularly reviews its forecast assumptions. As set out in its latest annual Forecast Evaluation Report, published in July 2025, the OBR noted that they are "currently conducting our regular summer supply stocktake, which involves research into our potential output forecast and its components."
As the Government’s independent official forecaster, the OBR has full discretion over the judgements underpinning its forecasts.
