We are often more certain than the evidence really allows.
More quotesIf a washing machine will cost less next month, waiting makes sense. Spread that decision across households and businesses and falling prices can delay spending, reduce sales, weaken investment and put pressure on wages. A small, predictable rise gives planned purchases a reason to happen sooner.
That sentence explains one mechanism behind the target. The person with a broken boiler is buying now because the kitchen is filling with water. The family whose rent and food rise faster than pay experiences no useful stimulus. The owner considering a new oven cares about customers, credit and future demand. Two per cent does not enter each decision in the same way.
Inflation is an average assembled from prices moving at different speeds. Income, debt and assets move differently too. One household owns a house with a fixed mortgage. Another rents, has no savings and spends most income on essentials. The same national figure reaches them through different bills and produces different losses.
The target itself is a convention built from experience and trade-offs, not a constant discovered in nature. Keeping some distance from deflation matters. So do credibility, wage adjustment and room for interest rates to respond. The tools operate with delays and land unevenly: mortgages reset, borrowing slows, hiring changes, savers and debtors receive different effects.
Public explanations need to name the danger being reduced, the alternatives rejected, the uncertainty in timing and the people exposed during correction. “Two per cent means price stability” deletes those choices. A tenant opening a renewal letter showing an eight per cent rise can see exactly what the slogan left out.
