Inflation is a general rise in prices over time. When it is high, the same amount of money buys fewer goods and services than it did before. Most people notice it at the grocery store, at the fuel pump and in rent, but the effects reach further.
How inflation is measured
Governments track inflation with a price index. The best known is the consumer price index (CPI), which follows the cost of a typical basket of goods and services such as food, housing, transport and healthcare. When the basket costs more than it did a year ago, the percentage change is the inflation rate. Your own inflation can differ from the official figure, because your spending is not the same as the average household’s.
Why prices rise
Economists point to several causes. Demand can grow faster than supply. Costs such as energy, wages or imported goods can go up and get passed on to buyers. A weaker currency can make imports more expensive. Often more than one factor is at work at the same time.
What central banks do
Many central banks aim to keep inflation low and stable, often around 2 percent, though targets differ by country. Their main tool is the interest rate. Raising rates makes borrowing more expensive, which tends to slow spending and cool price growth. Lowering them does the opposite.
Who is affected
- Savers lose purchasing power if their interest rate is lower than inflation.
- Borrowers with fixed-rate loans can benefit, because they repay with money that is worth less.
- Workers are better off only if wages rise at least as fast as prices.
- People on fixed incomes are often hit hardest, because their income does not adjust.
Practical steps for your budget
- Track your spending for a month to see where prices have changed most.
- Compare prices and buy in bulk for items you use regularly.
- Keep an emergency fund so that a price shock does not force you into debt.
- Check whether your savings earn more than the inflation rate.
- Be careful with variable-rate debt when interest rates are rising.
Inflation is a normal part of most economies. The goal is not to avoid it entirely, but to understand it well enough to plan around it.
