Bank Of England On 5 November, Explained: Inflation At 3.5%, A 6-3 Split And A Budget That Assumes Higher Rates

The Bank of England announces its next decision at noon on Thursday 5 November, with CPI inflation up to 3.5%, motor fuel prices up 29.8% on a year, three MPC members already voting for a rise in September, and a Budget whose forecasts assume Bank Rate climbs. A plain guide to what the Monetary Policy Committee is weighing, what markets and the OBR assume, and what it means for UK financial firms.

The Bank of England announces its next interest rate decision at noon on Thursday 5 November 2026, alongside a new Monetary Policy Report. Bank Rate stands at 3.75%. Since the September meeting, CPI inflation has risen to 3.5%, driven by a 29.8% annual jump in motor fuel prices, and the 28 October Budget's forecasts assume that Bank Rate rises over the next two years. This guide explains what the Monetary Policy Committee is weighing; it does not forecast the outcome.

The decision matters well beyond mortgages. Bank Rate feeds into gilt yields, sterling, the cost of client money and margin financing, and the funding costs of every UK financial firm. We covered the September hold and the Budget; this is the bridge between them.

What Will The Bank Of England Decide On 5 November?

Whether to hold Bank Rate at 3.75% or change it, and how to explain the path ahead. In September the Committee voted 6-3 to hold. Andrew Bailey, Sarah Breeden, Swati Dhingra, Clare Lombardelli, Dave Ramsden and Alan Taylor voted to keep rates unchanged; Megan Greene, Catherine L Mann and Huw Pill voted for a rise to 4%. The Committee also agreed unanimously to keep reducing its gilt holdings, with sales of £20bn a year alongside maturing gilts.

Its guidance was direct: "The Committee stands ready to act as necessary". It also restated the anchor for every decision: "Monetary policy is being set to ensure inflation comes down to 2% sustainably". The question for 5 November is whether the data since September has moved enough members to act.

Why Has UK Inflation Risen Again?

Mostly because of energy. The ONS reported on 21 October that CPI rose to 3.5% in September from 3.1% in August, with CPIH at 3.6%. In its words, "The largest upward contribution came from transport, particularly motor fuels." Motor fuel prices rose 29.8% over the year. Underlying measures moved less: core CPI, which excludes energy, food, alcohol and tobacco, rose to 2.8%, and services inflation to 3.7%.

The source of the shock is outside the UK. The Bank's September summary noted Brent crude at $106 a barrel on 14 September and UK wholesale gas at 207 pence a therm, driven by the Middle East conflict and events in Ukraine and Russia. It projected CPI at around 3.75% in the fourth quarter of 2026 and slightly above 4% in the first quarter of 2027. The risk it flagged is second-round effects, where higher energy prices feed into wages and other prices: "the risk of such effects, against which policy needs to lean, is greater the longer higher energy prices persist".

Some pressures were easing before the latest figures. Services inflation had fallen to 3.4% in August from 4.5% in March, food inflation was expected to be around 4% at the end of 2026 rather than the 6% to 7% previously feared, and underlying private sector wage growth was estimated at about 3.5%. Against that, Ofgem's price cap for October to December is £1,723 and is expected to rise substantially in the first quarter of 2027, which keeps household energy bills in the inflation figures well into next year.

What Do Markets And The OBR Assume About Bank Rate?

Both assume rates go up from here. At the September meeting the Bank noted that market interest rates implied a Bank Rate path peaking around 4.9% by the end of 2027. The Office for Budget Responsibility's forecast for the 28 October Budget assumed Bank Rate reaches just over 4.25% by mid-2027 and just over 4.5% by the end of the forecast, according to Newsquawk's summary, with the fiscal forecast using rates about 25 basis points higher on average than before.

That assumption is part of why the Budget's headroom shrank. Newsquawk reported headroom of £14.5bn against the main fiscal rule, down from £23.6bn in March, and a gilt remit of £250.6bn for 2026-27. Higher rates raise the cost of servicing government debt, which is why Chancellor John Healey's first Budget and the MPC's next decision are closely linked: the Treasury's room depends partly on where the Bank takes rates.

How Would A Change In Bank Rate Reach Markets?

Through expectations first and the rate itself second. Gilt yields, sterling and fixed mortgage pricing move on what markets expect the Bank to do over the next two years, so a decision that matches expectations can leave them little changed, while a surprise in the vote or the guidance can move them sharply. On Budget day the 10-year gilt yield was 5.321%, according to Dow Jones, below the 19-year high of 5.527% reached in early October. Variable-rate borrowing, interest on client cash and margin financing costs follow Bank Rate directly; fixed-rate products follow the market's expected path.

Our View: A Decision About Energy, Read Through Wages

The MPC cannot change the price of oil or gas. What it can influence is whether an energy shock becomes a lasting rise in wages and prices, which is why the September split turned on second-round risks rather than the headline figure. Core inflation at 2.8% and services at 3.7% are the numbers that will decide how many members move, and the Monetary Policy Report on 5 November will show how the Bank now sees them.

For UK financial firms, the useful preparation is the same whatever the vote: know how a change in Bank Rate flows through your client money, margin rates, funding costs and client communications, and be ready to explain it on the day.

“The MPC cannot set the price of energy. It can only decide how hard to lean against an energy shock becoming a wage and price spiral, and that is what 5 November is about.”

What It Means For Trading And Fintech Firms

  • Brokers and CFD providers: decision days bring sharp moves in sterling and gilt futures. Check margin settings, price feed resilience and client messaging for noon on 5 November.
  • Prop trading firms: scheduled UK releases often sit inside news-trading rules. Make sure your rule engine has the 5 November announcement time and treats it consistently across accounts.
  • Compliance leads: commentary around rate decisions should describe what the Bank did and why, not suggest positions. Review templates before the announcement, not after.
  • Treasury and finance teams: model the effect of a change in Bank Rate on interest earned on client money, overdraft and funding lines, and any rate-linked fees.
  • Fintech and trading startups: rate decisions are a test of your data pipeline. Every chart and alert that depends on gilt or sterling prices should be monitored through the announcement.

The Bottom Line

The Bank of England decides on 5 November with Bank Rate at 3.75%, CPI at 3.5% after a 29.8% jump in motor fuel prices, a Committee that split 6-3 in September, and a Budget that assumes rates rise towards 4.5%. Core inflation at 2.8% and services at 3.7% are the figures that will shape how far the MPC leans against the energy shock.
