The Bank of England raised its base rate by 25 basis points to 4%, the first increase in more than three years, with eight of nine MPC members voting in favour. The lone dissenter, Catherine Mann, wanted a half-point hike — a signal that the hawkish wing sees the Bank as already behind the curve. The immediate cause is not domestic overheating but an imported energy shock: oil prices persistently above $100 a barrel since hopes evaporated of reopening the Strait of Hormuz. The numbers tell the story of pass-through. UK CPI hit 3.5% in September. The Bank now forecasts 4.9% by mid-next year, up from 3.2% projected in July — a massive upward revision in a single quarter. The Ofgem energy cap is set to jump from £1,723 to £2,150 in January and rise again in April. Food price inflation could reach 4.75% by mid-2027. Real post-tax income is expected to fall this year and next. This is a cost-of-living compression arriving from the Persian Gulf, not from wage-price spirals. Governor Andrew Bailey framed the rate path as conflict-contingent, not mechanical. "Today's increase shouldn't be seen as the first in an inevitable long sequence of hikes. But unless the conflict in the Middle East is resolved, neither does it seem likely to be the last." That is an unusual admission: the Bank is telling markets its policy trajectory depends on a geopolitical variable it cannot influence. Oxford Economics' Andrew Goodwin expects another hike in December or February regardless. The MPC minutes reveal a three-way split. Alan Taylor characterised the move as a "risk-management 'one-for-now' insurance hike" — a dovish framing that implies one-and-done. Mann's push for 50bp reflects the opposite view: that the Bank's credibility requires front-loading pain. Bailey sits between, conditioning the path on oil. The split matters because it tells you nobody on the committee has conviction about where this ends. Chancellor John Healey's budget measures — a fuel duty freeze, VAT cut on electricity bills, and £100 energy payments to 20 million households — amount to fiscal cushioning of a monetary tightening. The MPC estimates the package shaves a quarter point off mid-2027 inflation. That is real but modest against a 4.9% peak forecast. The fiscal and monetary arms of the state are pulling in opposite directions: the Treasury absorbing some price pain, the Bank raising the cost of borrowing to suppress demand. Oil prices briefly dipped below $100 after Democratic victories in the US Congress, which some investors read as constraining Trump's capacity to prolong the Iran conflict. JD Vance publicly blamed the war and its inflationary impact for the Republican rout. Bailey acknowledged the price drop as "positive news" but said pipeline inflation was already baked in. The signal is clear: even a ceasefire tomorrow wouldn't unwind the price pressures already in transit through the supply chain. The structural problem is that UK monetary policy is now hostage to a conflict in which the UK has no direct negotiating role. The Bank is raising rates to manage inflation it cannot control at the source, imposing domestic demand destruction to offset an external supply shock. Mortgage holders and businesses pay the cost. Shadow chancellor Andrew Griffith called it "another headwind for hardworking families" — which is accurate if unhelpful. The real question is whether the Bank has any better tool, and the honest answer is that it does not.
