Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what assessment she has made of the impact of the level of gilt yields on forecast debt interest costs over the period 2026-27 to 2030-31.

Forecasts are produced independently by the Office for Budget Responsibility (OBR), which incorporates market expectations for gilt yields alongside other determinants of debt interest, including inflation and the stock and composition of government debt.

The OBR’s most recent forecast, including for debt interest costs, are available in the March 2026 Economic and Fiscal Outlook linked here: https://obr.uk/efo/economic-and-fiscal-outlook-march-2026/
