What Is Inflation and Why Does It Make Things Harder Even When Your Wages Go Up?

Why does inflation matter? Why are prices going up all the time?

Inflation is the general increase in the price level of goods and services over time, which means the same amount of money buys less than it did previously. In the UK this is measured primarily by the Consumer Prices Index, which tracks a representative basket of goods and services that households typically buy, and the Retail Prices Index which additionally includes housing costs.

The reason wage increases do not always offset inflation is that wages and prices do not move in lockstep. If prices rise seven percent and wages rise five percent, workers are effectively poorer even though their nominal salary is higher. The real wage, which is the purchasing power of your income, has fallen by approximately two percent even though the number on your payslip went up. This is the experience many UK workers had during the 2022 to 2024 cost of living crisis and again during the energy-price-driven inflation associated with the US-Iran conflict in early 2026.

Inflation affects different people differently depending on what they spend their money on. The official inflation measure tracks average spending patterns but individual inflation rates vary significantly. Someone who rents and has a long commute experiences more inflation when energy and rents rise than someone who owns their home mortgage-free and works from home. The inflation you personally experience can be significantly higher or lower than the headline rate.

The Bank of England's response to high inflation is to raise interest rates, which makes borrowing more expensive, reduces consumer spending and business investment, and thereby reduces demand and slows price increases. This works but has distributional effects: it is most painful for people with variable-rate mortgages and businesses with floating-rate debt, and least painful for people with savings accounts who benefit from higher interest rates on deposits. The same medicine that treats inflation makes life harder for some groups regardless of the disease's severity.

The personal inflation basket point explains why people often say their experience does not match the official figures. If you spend a high proportion of income on energy and food, both of which rose much faster than the headline rate in 2022 to 2024, your personal inflation rate was far above the CPI

Interest rate rises as an inflation tool are a blunt instrument that hits different groups differently. Mortgage holders with variable rates experienced a significant real income reduction from the Bank of England's rate rises that savers did not experience. The same policy has opposite effects depending on your balance sheet

The real versus nominal wage distinction is the most important single concept for understanding why wage rises do not automatically make people feel better off. Your nominal wage is the number you see. Your real wage is what that number buys. They move independently
