Bank of England pays the inflation insurance premium

The Bank of England raised Bank Rate from 3.75% to 4% today on an 8–1 vote. Catherine L Mann wanted a larger increase to 4.25%. I keep coming back to that split because it shows how much judgment this decision requires.

September UK CPI inflation was 3.5%, and the Bank expects around 5% by mid-2027. Recent activity has generally exceeded expectations. Yet the Bank says evidence of knock-on effects in other prices and wages remains limited, even as inflation pressure in the pipeline warrants action.

The timing is what makes this difficult for me. Monetary policy cannot influence global energy prices; the Bank aims to stop second-round effects from making inflation persistent. Some firms are shielded by hedging or fixed-price contracts, while others absorb higher costs in margins. The Bank judges those buffers mostly temporary if the energy shock persists.

I read this rate rise as an insurance premium against inflation arriving with a delay. The uncomfortable question is how much pain to impose now, before the pass-through is visible. The Bank says policy is not on a preset path. Given what it has laid out, I think that matters.
