The UK inflation rate of 3.1% for August 2026 was never going to shift the Bank of England (BoE) alone, and so it proved: the Monetary Policy Committee (MPC) voted 6-3 to hold Bank Rate at 3.75%, with three dissenters pushing for an immediate rise to 4%.
That voting split is not new. According to the Bank of England MPC minutes for September 2026, the committee divided in exactly the same 6-3 fashion at its July 2026 meeting. The hawks have not gained ground. But they have not retreated either, and that persistent minority is the detail markets should be watching.
What the UK Inflation Rate of 3.1% Actually Tells Us
The headline figure is almost entirely a fuel story. Motor fuel prices surged 23% in the 12 months to August, up from 15.5% in July, with petrol averaging 161.3p per litre and diesel reaching 181.8p. The Office for National Statistics (ONS) reports that the 6.9% monthly rise in fuel prices added 0.2 percentage points to the CPI reading on its own.
Strip that out and the picture is considerably calmer. Core CPI, which excludes food and energy, held at 2.6% for the second consecutive month. Services inflation remained at 3.4%. Food and non-alcoholic beverages rose just 1.3% annually, a rate last lower in September 2021, according to the ONS Consumer Price Inflation bulletin.
My read is that this is precisely the data the MPC majority needed to justify patience. Energy is doing the lifting; domestic inflation is not yet behaving badly. George Lagarias, chief economist at Forvis Mazars, put it directly: ‘Inflation figures have once again become too backward-looking, even for a central bank. The central bank can do precious little about such supply-side disruptions.’
He is right, up to a point. The MPC minutes acknowledge that protracted conflict in the Middle East has driven further increases in crude and refined energy prices since the previous meeting. Supply shocks are not amenable to rate rises. Hiking into an energy squeeze risks choking growth without doing much to bring petrol prices down.
The Pipeline Pressure Is Building Upstream
The more uncomfortable reading comes from the factory gate. Producer output prices rose 3.7% in the year to August, up from 3.3% in July. Producer input prices rose 6.1%, up from a revised 5.8% in July, according to the ONS Producer Price Inflation bulletin. Prices for basic metals, fabricated metal products and machinery rose 5.6% annually, with higher machining service costs cited as a primary driver.
That matters because input prices are a leading indicator. If crude oil costs stay elevated, those pressures will migrate into goods prices over the coming months. Thomas Pugh, chief economist at RSM UK, predicts inflation could reach around 4% early next year as supply chain impacts and second-round effects accumulate. He suggests the 2% target may not be reached until 2028.
Capital Economics told clients there is a ‘striking lack of any strengthening in domestic inflation’ in the August report, and for now that assessment holds. But James Smith, developed markets economist at ING, notes that food inflation could eventually turn negative given retreating fertiliser costs, before rising again as the effects of the Iran conflict feed through. The current calm in food prices may not last.
The broader measure including housing costs paints a marginally sharper picture. CPIH, which incorporates owner-occupiers’ housing costs, rose 3.3% in the year to August, up from 3.1% in July, with core CPIH at 2.9%. Neither figure is alarming, but neither is it moving in the right direction.
Ten-year gilt yields fell 5 basis points on the day to 5.35%, suggesting the bond market took some comfort from the contained core reading. Money market pricing put the probability of a hold at 80% going into the decision, implying a 20% chance of an immediate hike. The market got its hold. But with markets pricing in at least four rate rises by end-2027, taking Bank Rate to 4.75%, and Susannah Streeter at Wealth Club warning that borrowing costs look set to surge, the MPC’s window for patience is narrowing.
The committee also voted unanimously to continue reducing its stock of UK government bond purchases, a quiet but consistent tightening of financial conditions running in the background. The next rate decision is due on 5 November 2026. By then, September’s energy prices and another round of producer data will be in hand. If the hawks have not shifted the majority by then, the question is what it would take.
