Definition: Inflation Explained

Understand rising prices and how they are measured.

Key ideas

Inflation: causes and costs

Demand-pull inflation comes from too much spending chasing too few goods; cost-push inflation comes from rising costs like wages or oil. Moderate inflation is normal, but high inflation erodes savings, confuses price signals and can trigger a wage-price spiral.

Growth and the business cycle

Real GDP growth means the economy produces more, which can raise living standards. Economies move through a business cycle of boom and recession; a recession is commonly defined as two consecutive quarters of falling GDP, bringing falling incomes and rising unemployment.

Key term — inflation: A sustained rise in the general price level, which reduces what money can buy. In the UK it is measured with the Consumer Prices Index.

Worked example: Inflation Explained

Prices rise from £200 to £210. What is the inflation rate?

5% (£10 ÷ £200 × 100).

Answer: 5% (£10 ÷ £200 × 100).

Common mistakes
  • Confusing one price rise with inflation Inflation is a rise in the general price level — one product getting dearer while others stay flat is a relative price change, not inflation.
  • Assuming low interest rates are always good Cheap borrowing boosts spending but can fuel inflation and asset bubbles — rates must suit economic conditions.

Practice

Name one cause of demand-pull and one of cost-push inflation.
Too much spending vs rising costs.

Demand-pull: excessive consumer spending. Cost-push: rising oil or wage costs.

Why is high inflation bad for savers?
Think about what money buys.

It erodes the real value of savings — money buys less each year.

How might a central bank fight high inflation?
Think about the cost of borrowing.

Raise interest rates, making borrowing dearer and saving more attractive, which cools spending.

What does GDP stand for and what does it measure?
Gross…

Gross domestic product — the total value of goods and services produced in a country in a year.
