U.S./Israel-Iran War: the Middle East On Edge
NextFin News - The Bank of England's Monetary Policy Committee faces a near-decision on 5 November, with markets pricing an 86% chance of a 25 basis point rate increase to 4.0% after October's inflation print. The Office for National Statistics release on 21 October is the swing factor that could turn a divided committee into a unanimous hawkish vote.
Britain's central bank held Bank Rate at 3.75% on 17 September by a 6-3 majority, with three members already voting to raise rates by a quarter point to 4.0%. Inflation, measured by the Consumer Prices Index, stood at 3.1% in August against a 2% target. The next reading, due 21 October, is the last monthly inflation print the committee will see before it meets again on 5 November - and after a summer in which energy prices reignited the inflation problem, it may be the one that settles the argument.
The Arithmetic of a November Decision
The case for a November hike is, on its face, straightforward arithmetic. At its September meeting, the committee upgraded its near-term inflation assessment: staff now expect CPI to reach around 3.75% in the fourth quarter of 2026 and slightly above 4% in early 2027, up from the 3.2% average projected in the July Monetary Policy Report. That revision was not a forecasting accident. It followed a sharp move in energy markets after the previous report window closed.
At the close of business on 14 September, Brent crude stood at $106 a barrel and UK wholesale gas at 207 pence a therm - up 36% and 78% respectively since the period leading up to the July report. The direct pass-through is already visible at the pump: average petrol prices have risen from around 130 pence a litre in February, before the Middle East conflict intensified, to around 170 pence, with diesel up more sharply to around 190 pence. Motor fuels alone were contributing 0.6 percentage points to the August CPI print.
The bigger leg is still coming. Conditional on those same 14 September futures prices, the Ofgem energy price cap is expected to rise by 4% in the fourth quarter and by a further 24% in the first quarter of 2027. The government's temporary removal of VAT on household electricity from October will soften the blow by at least £45 off an average annual bill, but it does not erase the mechanical lift to the inflation index. The Bank's own letter to the Chancellor spelled out the transmission: indirect effects of higher energy prices working through firms' supply chains are expected to add around 0.6 percentage points to CPI by the first quarter of 2027.
If the October release lands anywhere near that trajectory, the three September dissenters will have the data on their side. Their argument, recorded in the minutes, was that "raising Bank Rate would put the MPC in a better place to address risks to price stability as these uncertainties unfold, especially since any resulting second-round effects, once entrenched, are costly to overcome." The six members who voted to hold did so with an explicit caveat: the committee "stands ready to act as necessary." In central-bank language, that is not a commitment to patience. It is an option on tightening.
There is also a calendar asymmetry working in the hawks' favour. Chancellor John Healey delivers the Autumn Budget on 28 October, just one week before the MPC meets. The Office for Budget Responsibility will publish updated forecasts for growth, inflation and borrowing on the same day. If the fiscal package leans toward restraint - targeted tax increases and spending discipline rather than new borrowing - it would hand the MPC political cover to tighten, because tighter fiscal policy does some of the anti-inflation work that monetary policy would otherwise have to do alone. If the Budget instead adds stimulus, the committee faces the worst combination: higher inflation from energy and higher demand from the Exchequer. Either way, the October inflation print will be read through the lens of the fiscal stance announced a week earlier.
A Cyclical Shock With a Structural Credibility Test
The right question is not whether the energy shock itself is permanent. It is not. The Bank's central projection has inflation falling back to the 2% target over 2027 and 2028, and energy futures curves continue to slope downward - the market's own bet that the conflict premium will fade. On that measure this is a cyclical episode: a supply-driven spike that mean-reverts once the geopolitical pressure eases. The committee's own forecast shows the job can be finished from the current 3.75% setting.
But the policy response to a cyclical shock can create a structural problem, and that is the real stakes of the November meeting. This is the second major energy shock in four years. After Russia's invasion of Ukraine in 2022, the Bank was widely criticized for keeping policy too loose for too long while inflation expectations unanchored. The committee's own summary in September acknowledged the lesson implicitly: risks to the inflation outlook are "tilted to the upside, and more so than at the time of the July Monetary Policy Report."
"Today, we've held Bank Rate at 3.75%. So far, higher global energy costs have had a limited effect on price and wage setting in the UK. But the longer this volatility persists, the bigger the impact it will have on inflation, and the more likely it is we will need to raise Bank Rate to ensure that inflation falls back to our 2% target."
That is Governor Andrew Bailey, speaking on 17 September. The conditional is doing the work. The Bank is not saying inflation has escaped. It is saying the cost of waiting has risen.
That is why the November decision is, in essence, a credibility bet rather than an inflation bet. The committee does not need to believe inflation will stay at 4% to justify a 25 basis point move. It needs to believe that being seen to wait - again - while a second energy shock passes through would do more damage to the 2% target's anchoring than a premature tightening would do to growth. The September minutes noted that firms' own-price expectations and broader survey measures of pricing pressures remain elevated. That is the variable that turns a cyclical shock into a structural one.
The committee is also fighting this battle on two fronts. On the same day it held rates in September, the MPC voted unanimously to reduce its stock of government bond purchases - the quantitative easing portfolio that still stood at £488 billion - to zero by the end of 2034, at an annual average pace of £46 billion through sales of £20 billion alongside maturing gilts. Quantitative tightening is the slower-acting sibling of rate policy, but it works on the same long end of the curve that determines mortgage and corporate borrowing costs. A rate hike in November would be the visible signal; the QT unwind is the steady pressure underneath it.
The Bond Market Is Already Doing the Tightening
Here is the second-order dynamic that makes the November hike less consequential than it looks - and more consequential at the same time. Long-dated gilt yields have already repriced the tightening cycle independently of the MPC. On 8 October, the 10-year gilt yield reached 5.527%, its highest level since 2007, while the 30-year yield climbed to 6.047%, the highest since 1998. By 15 October the 10-year had eased to 5.32%, but it remains roughly 0.8 percentage points above its level a year earlier.
The cross-country comparison shows how much of this is a UK-specific premium rather than a global move. On 16 October, the German 10-year bund yield stood at 3.42% and the US 10-year Treasury at about 5.10%. The UK 10-year, at 5.32%, trades nearly two full percentage points above Germany's - a gap that reflects not just the energy shock but the market's read of UK fiscal risk and inflation persistence. Global yields are up across the board, but the UK is paying more for it.
The transmission channel is direct. The September minutes recorded "full and fast pass-through" from rising overnight index swap rates to the lending rates that households and businesses actually face. The quoted rate on two-year fixed-rate mortgages is around 95 basis points higher than before the conflict began. In other words, financial conditions have already tightened by more than a single 25 basis point move could accomplish. The bond market is front-running the committee.
That creates an asymmetry for 5 November. If the MPC hikes, it largely ratifies what gilts have already priced - a 25 basis point adjustment with limited incremental tightening effect, since the long end has done the heavy lifting. If the MPC holds despite an inflation print at or above 3.75%, it risks a disorderly repricing: the market would infer that the committee is once again behind the curve, and the long end could sell off further, tightening conditions in an uncontrolled way. The paradox is that hiking in November may be the less hawkish option, because it restores the committee's control over the pace of tightening rather than ceding it to the gilt market.
Short-term rates tell the same story. The UK short-term interest rate curve is upward sloping and has risen further since the September Market Participants Survey closed, peaking at around 4.9% by the end of 2027. Market intelligence gathered after the survey window indicated that "the perceived probability of near-term increases in Bank Rate had risen." The 86% implied probability of a November hike, derived from LSEG pricing data, is simply the market's distillation of that curve. The swing has been rapid: nearly all respondents to the September Market Participants Survey, which closed on 4 September, expected Bank Rate to remain unchanged at that meeting, yet within weeks the short-term curve had moved to price a near-certain increase at the next decision.
The Strongest Case Against Hiking
The counter-thesis is not weak, and it starts with the Bank's own forecast. CPI excluding direct energy contributions is expected to be higher than headline inflation for much of the second half of the forecast, but the central projection still shows inflation returning to target without additional tightening. The domestic disinflation process has not broken. Services inflation - the MPC's preferred read on underlying pressure - was 3.4% in August, down from 4.5% in March, and the Bank's letter to the Chancellor described the decline as broad-based. Wage growth is decelerating: private sector regular Average Weekly Earnings grew 2.9% in the three months to July, down from 3.3% at the start of the year.
There is also judged to be spare capacity in the labour market, which constrains workers' ability to secure higher nominal wage growth - the very mechanism that would convert an energy spike into persistent inflation. On that reading, raising rates into a softening labour market, with mortgage rates already 95 basis points higher and household spending cautious, risks a policy error: crushing demand after the shock has already started to roll over. Energy futures slope downward. Food inflation is undershooting the Bank's expectations. The shock is smaller than 2022, there is more slack in the economy, and the committee's own models say patience works.
The rebuttal rests on timing and asymmetry rather than the level of inflation. The hawks' point is not that inflation will stay at 4%. It is that the window to prevent second-round effects is short, and the cost of being wrong is not symmetric. A premature 25 basis point hike that proves unnecessary can be reversed over the following year if the shock fades as futures predict. Entrenched wage and price setting, once it takes hold, cannot be undone without a far more painful tightening later. That is the lesson the committee drew from 2022, and it is the logic embedded in the dissenters' minutes.
What to Watch and Who It Hits
The base case is a 25 basis point increase to 4.0% on 5 November, triggered by an October CPI print at or above 3.5% with services inflation holding above 3.5%. The upside scenario - a larger or more explicitly hawkish move - requires momentum to accelerate: a print approaching 4% annualized with services re-accelerating toward 4%, which would signal that indirect effects are arriving faster than the Bank's supply-chain models assume. In that case, the 4.9% peak on the short-term rate curve would look like an underestimate rather than a ceiling.
The downside scenario - a hold - requires evidence that the domestic engine is cooling faster than the energy leg is heating up. Specifically: services inflation below 3.0%, regular wage growth below 2.5%, and energy futures rolling over further. Any one of those alone would not stop a hike; together they would give the six September hold voters cover to wait again, and the market's 86% probability would unwind quickly.
The distributional impact is already visible. Savers and money-market funds benefit from higher short rates, and annuity providers can offer incomes at levels not seen in more than a decade on the back of elevated gilt yields. The exposed side is equally clear: households rolling onto new two-year fixed mortgages face rates roughly a percentage point above pre-conflict levels, highly leveraged borrowers face refinancing risk, and holders of long-duration gilts remain vulnerable to a further term-premium repricing if the committee is perceived as behind the curve.
The specific falsifying signal for the hike thesis is the combination of the October services print and the wage data: if services inflation prints below 3.0% alongside regular Average Weekly Earnings growth below 2.5%, the November hike case collapses, because it would show the domestic disinflation process overpowering the energy leg. Until that data arrives, the burden of proof sits with the doves.
This is not a bet that inflation will stay high. It is a bet that the Bank of England cannot afford to be wrong about inflation one more time.
