Inflation is one of the few economic statistics that ordinary households experience directly, in the supermarket aisle and on the standing charge line of an energy bill. It is also one of the most widely misunderstood. When the headline rate falls, the political message is usually one of relief. The lived experience is often something else entirely.
The distinction matters. A falling inflation rate does not mean prices are coming down. It means they are rising more slowly than they were. The price level itself, the cumulative total of everything that happened during the shock, stays where it is. That single point explains most of the gap between the official data and the mood in the country.
The arithmetic of a slower rise
Consider a weekly shop that cost 100 pounds four years ago and 128 pounds today. If inflation now runs at two per cent rather than eleven, the same basket next year costs a little under 131 pounds. The rate has collapsed. The bill has not. Nothing about disinflation reverses the earlier increase, and nothing about it restores the purchasing power that was lost while wages lagged behind.
The Office for National Statistics publishes the consumer prices index as a year-on-year comparison precisely because policymakers care about momentum. Households, by contrast, compare today against a remembered normal that may be several years old. Both views are legitimate. They simply answer different questions, and the political argument that follows tends to conflate them.
Why the composition of the basket matters
Headline inflation is an average, and averages conceal distribution. Energy, food and rent have behaved very differently from electronics, clothing and airfares. A household that spends a large share of its income on heating a poorly insulated home and feeding a family will have experienced an effective inflation rate well above the published figure. A higher-income household with more discretionary spending will have experienced less.
This is why analysis from bodies such as the Institute for Fiscal Studies consistently finds that inflation shocks are regressive. The poorest tenth of households allocate roughly twice the share of spending to essentials that the richest tenth do. When essentials lead the price rise, the burden lands unevenly regardless of what the national average records.
The interest rate transmission problem
The Bank of England raised rates aggressively to bring inflation down, and the mechanism worked broadly as textbooks suggest. But the pain of that policy was also unevenly distributed. Mortgage holders on variable rates felt it within weeks. Those on five-year fixes felt nothing at all until their deal expired, sometimes years later. Renters felt it indirectly, through landlords passing on higher borrowing costs.
That staggered transmission means the squeeze from monetary tightening does not end when the inflation target is met. A significant cohort of borrowers is still rolling off deals struck in a cheaper era, and each one absorbs a step change in monthly outgoings at the moment of renewal.
Wages, the slow variable
Real incomes recover when pay growth outpaces prices for a sustained period, not for a quarter or two. Because the earlier shock was large, closing the gap takes years of modest outperformance rather than a single strong settlement. Research from the Resolution Foundation has repeatedly made the point that Britain entered this period with an unusually weak record on productivity and pay growth, which lengthens the repair job considerably.
There is also a compositional trap in the wage data. Average earnings can rise simply because lower-paid roles disappear from the sample, and can appear to stall when employment is expanding at the bottom of the distribution. Reading either as a clean signal about living standards is a mistake that professional forecasters try hard to avoid and political communication rarely does.
What to watch instead of the headline
Three indicators tell a more useful story than the monthly headline. Services inflation reveals how much of the price pressure is domestic rather than imported. Regular pay growth excluding bonuses shows whether incomes are genuinely catching up. And the household saving ratio indicates whether families are rebuilding buffers or still drawing them down.
Taken together these suggest a slow, uneven normalisation rather than a clean recovery. The economy can be stabilising in aggregate while a substantial minority of households remain worse off than they were, with lower savings, higher fixed costs and no realistic prospect of the old price level returning. Understanding that is the difference between reading the data and understanding the country.
The fiscal shadow
Inflation also rewrote the public finances. It inflated nominal tax receipts, eroded the real value of departmental budgets set in cash terms, and raised the cost of index-linked government debt. That combination is why the arithmetic facing the Treasury looks tighter than a simple growth figure would imply, and why the bond market has become an unusually loud participant in domestic politics.
