Britain's cost-of-living squeeze deepened in September. The Office for National Statistics said consumer price inflation rose to 3.5% in the 12 months to September, up from 3.1% in August and above the 3.4% median forecast in a Reuters poll of economists. It is the fastest annual pace since October 2025 — and a full half-point above the 3.0% the Bank of England itself projected back in July.
The timing is what gives this print its edge. It lands two weeks before the Bank's November 5 rate decision, and traders now treat a quarter-point hike to 4.00% as near-certain. That would be the first increase in three years, ending a hold that has lasted since the US-Iran war broke out in February. Sterling ticked higher against the dollar and euro on the news, while gilt yields pushed up as traders locked in the November move.
Fuel did the damage: petrol rose 8.2 pence per litre to 169.5 pence on average, the highest since August 2022, while diesel climbed 10.7 pence to 192.5 pence, the dearest since July 2022. Motor fuel is now up 29.8% on the year — restaurants and hotels were the only meaningful offset.
The details underneath the headline are what will worry Threadneedle Street. Core CPI, which strips out energy, food, alcohol and tobacco, climbed to 2.8% from 2.6% — exactly as forecast. But services inflation, the gauge Bank officials trust most for domestically generated pressure, jumped 0.3 points to 3.7%, its firmest reading in four months and above both the 3.6% consensus and the Bank's own 3.3% call. On a monthly basis, consumer prices rose 0.4%, also topping the 0.3% forecast.
Why it matters
The gap between Bank Rate and inflation has all but vanished. With the policy rate held at 3.75% in September, the margin over headline CPI has compressed to 0.25 percentage points — and against services inflation of 3.7%, the real policy rate is essentially flat. That is a thin cushion for a central bank with a 2% target, and it explains why money markets moved so fast.

Zoom out and Britain is now the hawk in the European pack. September inflation in France and Germany came in at 3.4% and 3.3% respectively, leaving the UK above its nearest neighbours. The producer-price pipeline looks worse: input prices rose 8.3% on the year, the loftiest since May, with crude oil alone up 14% on the month. Across the Atlantic, the Federal Reserve raised rates in mid-September and 10-year Treasury yields sat near 5.09% late last week. Markets still see an 89% chance of another Fed hike at its December meeting, per CME FedWatch. The global rate backdrop is moving one way, and the Bank of England can hardly lean the other. Sterling's edge over the euro has a second driver: GBP/EUR sits near multi-year highs as traders price tighter UK policy against French political risk. That is the box Threadneedle Street is in: pause and inflation keeps running, hike and the mortgage squeeze tightens further.
There is also a political clock ticking. Chancellor John Healey delivers his first budget on October 28, a week from now, and will face demands for energy-bill support for the hardest-hit households. That task gets harder with the fiscal backdrop: public borrowing hit GBP24.52 billion in September, up from GBP17.25 billion in August and above last year's GBP22.76 billion, running hotter than the Office for Budget Responsibility's forecast.

What to watch
- BoE Governor Andrew Bailey speaks at a fireside chat today at 2:00pm London time — his first chance to address the overshoot in public.
- The November 5 rate decision: markets have a 25bp move to 4.00% near-fully priced; a hold would now be the shock.
- The October 28 budget: expect fuel-duty and household-support signals from Healey, plus any fiscal tightening that changes the Bank's calculus.
- The next CPI print on November 18 — the first reading the Bank will see after its decision.
- Sterling: GBP rose against the dollar and euro on the print; for the technical setup, see GBP/USD price analysis.
MarketRadar take
The November 5 hike is as close to certain as these things get — a hot headline, sticky services, pipeline pressure from producer prices, and a labour market that is stabilising rather than cracking. That keeps the near-term tilt supportive for sterling and unfriendly for gilts into the decision. The nuance, courtesy of Brown Brothers Harriman's Elias Haddad: the swaps curve already prices about 113 basis points of tightening over twelve months, roughly four to five quarter-point moves, and BBH sees scope for less. With the economy running below capacity, real wages barely growing, and the policy rate sitting near the top of the Bank's own estimated 2–4% neutral range, the risk from here is less the hike itself and more the market's appetite for the hikes priced after it.
