Bank of England MPC Preview: Budget 2026, 3.1% Inflation and Energy Costs on the 5 November Agenda
Written by Paul Thompson, Acorn.finance. Figures reported as at .
The Bank of England's next Monetary Policy Committee (MPC) interest rate decision will be announced on Thursday 5 November 2026 at 12:00pm, accompanied by the quarterly Monetary Policy Report and updated economic projections.
Three published factors are reported as shaping that decision: the Autumn Budget on 28 October, energy prices affected by the Middle East conflict, and headline inflation that has moved back away from the 2% target. This article sets out what has already been published or reported, with the date it applied, and explains how each lending mechanism works. It does not forecast the outcome.
In brief
- The next MPC decision is Thursday 5 November 2026 at 12:00pm, published with the Monetary Policy Report.
- The base rate has been held at 3.75% since the September 2026 meeting; headline CPI stands at 3.1%.
- The 28 October Autumn Budget, Middle East energy costs and the CPI rebound are the factors reported as shaping the decision.
- Market reporting suggests expectations of an immediate November cut have faded, with the committee reported to be split.
- Acorn.finance reports these figures and explains how facilities are priced; we do not forecast rates or advise on when to borrow.

| Item | Published position | Source |
|---|---|---|
| Next MPC decision | Thursday 5 November 2026, 12:00pm, with the quarterly Monetary Policy Report and projections | Bank of England |
| Bank Rate | 3.75%, held at the September 2026 meeting | Bank of England |
| Headline CPI | 3.1%, having moved back up after nearing the 2.0% target earlier in the year | Office for National Statistics |
| Autumn Budget | Wednesday 28 October 2026, eight days before the MPC decision | HM Treasury |
| Energy inputs | Brent crude reported toward $100 a barrel; UK wholesale gas toward 185p per therm | Market reporting, 20 October 2026 |
The three factors in focus
1. The Autumn Budget of 28 October 2026
The Chancellor delivers the Autumn Budget eight days before the MPC meets. The Committee does not set rates in a vacuum: its forecast models depend heavily on the Office for Budget Responsibility assessment and the government's borrowing remit.
The mechanics are well established. If a Budget signals higher borrowing or major public capital expenditure, the Debt Management Office must issue more gilts. Greater supply of UK government debt tends to push gilt yields upward, and wholesale swap rates — the basis on which lenders price fixed terms — move with them, independently of the base rate. Reported decisions to protect Capital Gains Tax rates and business investment have eased market anxiety, while any expansionary fiscal policy would add to domestic demand.

2. The Middle East conflict and commodity costs
Renewed conflict involving Iran has introduced a supply-side cost shock. Brent crude has climbed toward $100 a barrel, and UK wholesale natural gas prices have been reported surging toward 185p per therm.
Central banks typically look through temporary commodity spikes when domestic demand is weak. The difficulty arises when energy costs rise alongside existing wage pressures: the Committee has described concern about “second-round effects”, where higher logistics and heating costs are passed on to consumers and become embedded in contracts and salary expectations.

3. Headline CPI back at 3.1%
After nearing the 2.0% target earlier in the year, UK headline Consumer Price Inflation accelerated back to 3.1%, against a 2% target. The base rate was held at 3.75% in September.
Market reporting through the autumn put expectations on a path of further cuts toward 3.00%–3.25%. With inflation at 3.1% and energy inputs rising, that reporting indicates expectations of an immediate 25-basis-point November cut have largely dissolved. Press accounts describe the Committee as split between a hold at 3.75% while the energy picture becomes clearer, and members who have argued policy may need to tighten further if energy costs remain elevated through the first quarter of 2027.

How these mechanisms reach commercial and property borrowing
The table below states where things stand as reported, and how each mechanism operates. It does not predict what will happen to pricing at or after the November meeting.
| Metric or facility | Where things stand, as reported | How the mechanism works |
|---|---|---|
| SONIA and fixed swap rates | Two-year and five-year swap rates have begun ticking up as markets price inflation for longer | Lenders set fixed commercial and residential matrices from the swap curve as well as the base rate, so fixed pricing moves with swaps |
| Tracker and variable-rate debt | Priced directly off the 3.75% base rate | Base-rate-linked facilities — trackers, bridging and development drawdowns — move automatically when the MPC changes the rate, without a lender re-offer |
| Debt service coverage (DSCR) | Lenders assess medical, care and commercial deals at 145%–160% stress | Underwriters apply a stress rate, typically base rate or swap plus 2%–3%; that assumption sets the borrowing cap for a given income |
What we report, and what we will not tell you
Acorn.finance does not forecast the base rate, swap rates or fixed-product pricing, and we do not tell borrowers when to borrow. Nobody outside the Committee knows how the 5 November vote will go, and we will not pretend otherwise.
What we can do is put the published figures in front of you with their dates and sources, explain how each facility is priced, and set out the whole-of-market options available to your situation — so that the decision on timing, structure and amount remains yours, made with the facts rather than a prediction.

Your questions on the record
- When is the next Bank of England interest rate decision?
- The next Monetary Policy Committee (MPC) decision is due on Thursday 5 November 2026 at 12:00pm, published alongside the quarterly Monetary Policy Report and updated economic projections.
- What is the current Bank of England base rate?
- The MPC held the base rate at 3.75% at its September 2026 meeting. This article reports that position as at 20 October 2026. The rate can change at any subsequent meeting.
- Does Acorn.finance forecast interest rates?
- No. We do not forecast the base rate, swap rates or fixed-product pricing, and we do not tell borrowers when to borrow. We report information that is already published or reported, with the date it applied, so that clients can reach their own view.
- How does a base rate change reach my payments?
- Facilities priced directly off the base rate — such as many tracker, bridging and development drawdown facilities — move automatically when the MPC changes the rate. Fixed commercial and residential terms are priced off swap curves, so lender fixed-rate matrices reflect swap pricing as well as the base rate.
