Chancellor Faces £20bn Black Hole in Budget with OBR Downgrading Productivity Forecast

Strategic Insights -

As the government's economic policy continues to struggle with internal dissonance, Chancellor Rachel Reeves faces a daunting challenge in the upcoming Budget, with the Office for Budget Responsibility (OBR) downgrading its productivity forecast by £20bn, exacerbating the existing £30bn-£40bn financial gap. This move has significant implications for the UK's public finances, requiring tax hikes or cuts to state spending to cover the shortfall.

Key Takeaways:

  • The OBR's decision to downgrade its productivity forecast by 0.3 percentage points, from 1.4% to 1.1%, is a substantial reduction and points to lower overall economic growth in the years ahead.
  • The 10% reduction in productivity forecast translates to a £20bn reduction in tax revenues and an increase in public spending, creating an additional "black hole" in the Chancellor's plans.
  • The Treasury and OBR will engage in an iterative process, exchanging proposals, projections, and policy assumptions before Budget day, in an effort to persuade the OBR to adjust its previously pessimistic view of productivity upwards.
  • Chancellor Rachel Reeves faces a choice between policies that would be politically effective in limiting the historical slide in the government's popularity and those that would protect longer-term economic growth.
  • The IFS has pointed out that raising income tax is the only way to balance the Budget, with attempts to raise smaller taxes causing unnecessary economic damage.
  • The Chancellor should consider raising the basic rate of income tax, applying to all forms of income, including rent, dividends, and interest, to ensure a fair and significant revenue increase.
  • The Budget speech should make clear that control of public spending, particularly defense, cannot be left to one side, even by a Labour administration.
