The Autumn Budget and Sterling: Risks, Reactions, and What Businesses Should Expect

Sterling has faced increased pressure in recent months as markets look ahead to the UK’s Autumn Budget. Concerns about UK growth, potential tax rises and wider fiscal tightening have all contributed to weaker investor confidence.

Reports that the Office for Budget Responsibility (OBR) is preparing a significant downgrade to UK growth and productivity forecasts have added further uncertainty. These developments helped push GBP to notable lows in early November, including a two and a half year low against the euro and a seven month low against the dollar.


When the Budget Will Be Announced

The Chancellor will deliver the Autumn Budget on Wednesday 26 November, usually beginning around 12.30pm after Prime Minister’s Questions. Key measures may be announced or signalled beforehand, which means the pound could start moving before the official speech.


What Businesses Can Expect

Although the full details will be confirmed on budget day, early commentary suggests the government may introduce:

  • Potential tax rises: including income tax, National Insurance and VAT adjustments.
  • Changes to business and investment taxes: including capital gains tax, inheritance tax and reforms aimed at property or corporate investment.
  • Tighter spending controls: to meet fiscal rules and maintain credibility in the bond market.

How the Budget Could Affect Sterling

Fiscal policy decisions often have a direct impact on currency markets. Sterling may react to the budget in several ways.

1. Investor confidence in the UK’s financial position

A credible, balanced budget could support Sterling. A budget seen as negative for growth or borrowing levels could add pressure to GBP.


2. Bond market reaction

Movements in gilt yields often influence Sterling directly. A calm reaction may provide stability, while rising yields or concerns about borrowing could cause volatility.


3. Bank of England expectations

If the budget signals tighter fiscal conditions through higher taxes or lower spending, markets may expect earlier or deeper interest rate reductions, which typically weigh on GBP in the short term.


The Role of the OBR Forecasts

The OBR’s accompanying report could significantly impact market sentiment. Businesses should watch for revisions to:

  • Growth and productivity forecasts
  • Borrowing projections
  • Long term sustainability of public finances

A significant downgrade could reinforce concerns about the UK’s long term outlook and weaken GBP. A more stable assessment could help restore some confidence in the pound.


What Businesses Should Review Now

Periods surrounding major fiscal announcements can bring sharp currency movements. Businesses may want to review:

  • Existing hedging strategies
  • Timing for large international payments
  • Forward contract opportunities
  • Sensitivity to GBP movements in supplier and revenue chains
