If your weekly shop costs more than it did a few years ago, you have experienced inflation first-hand. Understanding it helps you make smarter decisions about saving, borrowing and investing.
What Is Inflation?
Inflation is the rate at which the general level of prices rises over time. When inflation is 5%, something that cost 100 last year costs about 105 today. Put another way, each unit of your currency buys a little less than before.
Governments measure inflation by tracking the price of a “basket” of common goods and services, such as food, fuel, rent, clothing and transport.
What Causes Inflation?
- Demand-pull inflation: when demand for goods and services grows faster than supply, prices rise.
- Cost-push inflation: when production costs such as energy, raw materials or wages increase, businesses pass those costs on.
- Monetary factors: when the amount of money in an economy grows rapidly, its value can fall.
- Expectations: if people expect prices to rise, they may demand higher wages and businesses may raise prices in advance.
Is Some Inflation Good?
Most central banks target low, stable inflation of around 2% a year. Mild inflation encourages spending and investment rather than hoarding cash. Deflation, where prices fall, can be harmful because people delay purchases and the economy slows. Very high inflation is damaging because it erodes savings and makes planning difficult.
How Inflation Affects You
Savings
If your savings account pays 2% while inflation is 5%, your money is losing about 3% of its real value every year. This is called a negative real return.
Debt
Inflation can actually help borrowers with fixed-rate debt, because the amount owed stays the same while wages and prices rise. However, central banks often raise interest rates to fight inflation, which makes variable-rate loans and new borrowing more expensive.
Wages
If your pay rise is smaller than inflation, you have effectively had a pay cut in real terms, even though your salary number went up.
Pensions and Investments
Over long periods, assets such as shares and property have tended to outpace inflation, which is one reason long-term investing is important.
How Central Banks Fight Inflation
The main tool is the interest rate. Raising rates makes borrowing more expensive and saving more attractive, which cools spending and slows price rises. Lowering rates does the opposite to support a weak economy.
How to Protect Your Money
- Shop around for savings rates rather than leaving money in a low-interest account.
- Invest for the long term in diversified assets for goals more than five years away.
- Consider inflation-linked products, such as inflation-linked government bonds, where available.
- Fix costs where sensible, such as locking in a fixed mortgage rate or energy tariff.
- Review your budget regularly, because last year’s numbers may no longer be accurate.
- Negotiate your pay using inflation data to support your case.
Final Thoughts
Inflation is a constant, quiet force acting on every financial decision you make. By understanding how it works, you can keep your savings working, borrow wisely and make sure your money keeps its value over time.
