UK Autumn Budget 2025: Record tax burden, OBR leak, and strong market volatility


Record tax burden.

Tax increases of around £40 billion a year.
Taxes will reach 38 percent of GDP by 2029-30, the highest level since 1948.

Main tax measures:
  • Employer NICs at 15 percent and threshold cut to £5,000
  • IRPEF thresholds frozen: approximately 6 million taxpayers will move into higher brackets.
  • Abolition of the Non-Dom regime
  • Reduction of inheritance tax relief
  • 20 percent “Mansion tax” on high-rate real estate capital gains
Public spending:
Over £70 billion allocated to the NHS and defence, funded by taxes and optimistic growth estimates.

OBR Leak: Immediate Shock on Markets
The full version of the OBR report leaked hours before the official statement.

Market reaction:
  • Gilt yields +15 bps
  • Pound and highly volatile stocks
  • FTSE 250 hit hardest
Stealth taxes and political risk
Fiscal drag:

The freezing of thresholds will mean that, by 2028, one in four taxpayers will pay higher rates.

NIC Increase:
Risk of Lower Wage Increases and Slower Hiring.

Political reactions:
The opposition calls the move "a betrayal of workers."
Internal tensions could erode the government's political capital.

Latest Markets View
  • Bonds: Gilts cautiously priced, but risks remain elevated.

Discussion:
Will the record tax burden stifle growth?
How serious is the OBR leak for market confidence?
Will hidden taxes spark enough protests to force the government to change course?
