The FT reported yesterday evening that the OBR is expected to cut its trend productivity forecast by 0.3pp in its upcoming Economic and Fiscal Outlook (released alongside the Nov 26 budget), larger than the 0.1-0.2pp that had been expected by most analysts/independent forecasters.

- The IFS’ Green Budget (here) estimated that each 0.1pp downgrade to productivity would increase 2029-2030 PSNB by GBP7bln, so this downgrade implies a GBP21bln hit to public finances. A reminder that the YTD tracking error with existing OBR projections is also GBP7.23bln.
- This productivity downgrade lends support to reports suggesting the Chancellor is looking to break Labour’s election manifesto pledge and raise income tax at the budget.
- More disappointment for the Chancellor has come from the Treasury Committee, who suggested any growth impulse from the UK’s National Wealth Fund will be limited due to its small size: “The current NWF’s size could limit its strategic impact on economic growth”…. “Its ambitions to deliver significant regional and economic growth are likely to be very challenging.” (via BBG)
- A reminder that the Chancellor is hoping that factors such as lower borrowing costs (which crucially will depend on the 10-day window the OBR uses to base its projections on), growth-friendly policies (e.g. trade deals, planning reforms) and faster-than-expected spot growth will provide some offset to the fiscal hit from the productivity downgrade.
