In its October Economic and Fiscal Outlook (EFO), the independent Office for Budget Responsibility (OBR) set out its assessment of the economic impact of government policies announced at the Budget and Spending Review. The OBR noted that government policies overall had a small effect on inflation, with the price level 0.3% higher at the end of the forecast horizon as a result of Budget and Spending Review measures. The EFO captures the impact of policy measures, specifically referred to in box 2.1 in the October publication.
