Waiting on Debt Reform Will Double the Cost, OBR Warns

The UK's Office for Budget Responsibility said fiscal adjustment needed to correct an unsustainable debt trajectory would be twice as large if delayed to mid-century versus the early 2030s. The warning, presented July 7, 2026, reflects a core tension: governments face four-to-five-year electoral cycles, but debt consequences unfold over decades. Three spending pressures—defence, pensions, and health—will simultaneously surge without policy change, pushing debt-to-GDP into permanent ascent from the 2040s onward.
