Question to the HM Treasury:

To ask His Majesty's Government what assessment they have made of the accuracy of economic predictions submitted to them by the Office of Budget Responsibility.

Economic forecasts, including assessments of the impact of policy decisions, are the responsibility of the independent Office for Budget Responsibility (OBR).

The OBR is required to produce a Forecast Evaluation Report (FER) each year under the Budget Responsibility and National Audit Act (2011). The OBR is required to explain the reasons for divergence between its forecasts and subsequent outturns, to support future forecast improvements.

The latest Forecast Evaluation Report was published in July 2025 and can be found on their website.
