A second upside data surprise confirms a November hike, but the pound's muted reaction shows the good news is priced.
UK inflation overshot expectations in September, but the pound's initial jump was faded within minutes as markets judged the beat confirms a Bank of England rate hike they had already priced.
The pound-to-euro exchange rate spiked towards Tuesday's 1.1922 high on the release before settling back at 1.1917, and the pound-to-dollar rate followed the same path to trade at 1.3373.
CPI rose 3.5% in the year to September, up from 3.1% in August and above the 3.4% consensus, according to the ONS.
The beat lands a day after unemployment fell unexpectedly to 4.7%, and together the two releases close off the Bank of England's remaining arguments for holding Bank Rate at 3.75% on 5 November.
Markets priced a near 100% chance of a November hike before the release, which is why a beat that would have moved the pound a month ago now produces a spike and a fade: markets are now looking at what happens beyond November.
The details were firm across the board: core CPI rose to 2.8% from 2.6%, against a 2.7% consensus. Services inflation rose to 3.7% from 3.4%, against a 3.5% consensus. Goods inflation rose to 3.2% from 2.7%, its highest since September 2023, CPI rose 0.4% on the month, against little change in September 2025
Energy Did the Damage
Motor fuels made the largest upward contribution, with petrol up 8.2p a litre on the month to 169.5p and diesel up 10.7p to 192.5p, both at their highest since 2022.
Motor fuel prices are up 29.8% on the year, and kerosene rose 22.7% in the month alone.
That is the direct effect of the Middle East conflict feeding through, and it keeps the Bank focused on whether households and firms respond by pushing up wages and prices.
But Services is the Bank's Problem
The rise in services inflation to 3.7% is the figure that matters most for the Monetary Policy Committee, because it measures domestic price pressure that energy cannot explain.
Air fares fell by less than a year ago, and recreational and cultural services rose 5.1% on the year, with live music and computer game downloads among the drivers.
Restaurants and hotels offered the main offset, with the annual rate falling to 3.8% from 4.1% as hotel prices rose more slowly.
Governor Andrew Bailey said on Friday that second-round effects from the energy shock remained subdued, and the September MPC minutes implied those effects were no precondition for a hike.
Services at 3.7% makes that case for him to swing behind a hike.

Talk to a specialistWhy the Pound Faded
The pound's gains rest on a market pricing a series of hikes into 2027, and the analyst community is less convinced than the market that the Bank delivers them.
"We agree with current pricing for a high chance of a BoE interest rate increase at its next meeting in November. However, unlike the market, we do not expect a series of interest rate hikes," says Joseph Capurso, Head of International Economics at Commonwealth Bank of Australia, in a note published ahead of the release.
OCBC's Sim Moh Siong says sterling has near-term support from resilient UK data and Bank of England tightening expectations, but the bar for further gains is rising.
"Aggressive rate pricing and looming Budget risks argue against chasing GBP higher," he says.
That is the setup the fade reflects: with four hikes priced over the coming year, a single data point cannot add to the rate path, and the Budget on 28 October is the next event capable of moving it.
Food inflation offers the Bank some comfort, holding at 1.3%, its lowest since 2021, though the Food and Drink Federation expects food inflation to arrive later and persist for longer as manufacturers struggle to pass on costs.
What It Means for the Pound
Monday's week ahead forecast looked for the pound-to-euro rate to unwind from overbought conditions, and warned that above-consensus data would keep that pullback at bay.
Two beats in two days have held the pullback off, and the faded reaction to the second suggests the data-driven leg of the rally is complete.
The pair sits more than a percent above its 21-day moving average, and our in-house modelling says that gap must close through a pullback or consolidation.
A consolidation near current levels is now the base case, with the rising 21-day average closing the gap from below while the data keeps sterling bid.
Friday's retail sales and PMI figures are the final tests before the Budget, and a hold above 1.19 through them would set the pound-to-euro rate up to challenge 1.20 once the Budget passes without incident.
