Inflation and your savings

What inflation is

Inflation is the general rise in prices over time. When it happens, each dollar buys a little less than it did before. In Australia the Reserve Bank aims to keep inflation within a target band over time, which means even a well-managed economy expects prices to keep rising, just slowly.

A small rise each year does not feel like much. Over a working life or a retirement it compounds, in the same way interest does. That is why long-term thinkers pay attention to it: the effect is quiet, gradual and easy to miss until it is large.

Why savings lose buying power

Money in a bank account keeps its number but not its value. As a simple illustration, if prices rise by 3% in a year and your savings earn 1%, you can buy roughly 2% less with them at the end of the year than at the start, even though the balance went up.

Economists call the return after inflation the real return. It is the number that tells you whether your buying power actually grew. Tax matters too: interest is usually taxable, so the real return after tax can be lower again.

Our book on the history of money traces how this happened over centuries, from coins that rulers diluted to modern currencies backed by government decree.

How people think about outpacing inflation

There is no single answer, and every option involves a trade-off between stability, growth, income and access. Broadly, people weigh up assets like these:

• Cash and term deposits: stable and easy to access, but interest has often been close to or below inflation after tax.
• Bonds: regular income, but fixed payments lose value when inflation rises unexpectedly.
• Shares: a claim on businesses that may be able to raise prices, but values can fall sharply, sometimes for years.
• Property: a real asset with rental income, but costly to buy and sell, hard to divide and exposed to interest rates.
• Gold: a long history as a store of value, but no income and long periods of flat or falling prices.
• Digital assets: some have a fixed or limited supply, but they are young, volatile and high-risk.

None of these is guaranteed to keep up with inflation in any given period. How much of each, if any, suits a person depends on their goals, time frame and tolerance for loss, which is what a licensed financial adviser is there to help with.

Where Bitcoin's fixed supply fits in

Bitcoin's software caps its supply at 21 million coins, and new coins are released on a schedule that roughly halves every four years. No central bank can decide to issue more. For people worried about currencies losing value, that predictability is the core of the appeal, and it is why some describe Bitcoin as digital gold.

The counter-arguments are serious. Bitcoin's price is driven by demand as well as supply, and demand can change quickly. Its price has fallen by more than 70% more than once, including during periods when prices in the shops were rising fast. A fixed supply does not by itself make an asset a reliable store of value, and Bitcoin's history is short compared with gold, property or shares.

The risks to keep in view

Trying to outpace inflation usually means accepting more risk. With digital assets that risk is high: prices can swing widely, platforms can fail, keys can be lost and scams are common. Holding too much cash carries a quieter risk, the slow loss of buying power. Neither risk disappears by ignoring it, which is why it helps to understand both before making any decision with a licensed adviser.

Questions about inflation and savings

What does inflation do to savings?

Inflation means prices rise over time, so the same amount of money buys less. Savings that earn less than the inflation rate lose buying power, even though the dollar balance does not fall.

What is a real return?

A real return is what an asset earns after allowing for inflation. It is a more honest measure of whether buying power grew than the headline number alone.

Is Bitcoin a hedge against inflation?

It is debated. Its fixed supply is the main argument for the idea, but its price has been far more volatile than inflation and has fallen sharply at times when consumer prices were rising. No asset is a guaranteed hedge.

Is there a way to outpace inflation without risk?

No. Every asset involves a trade-off. Assets with lower volatility have often struggled to keep up with inflation, while assets that might grow faster can also fall in value.

Where can I explore inflation with my own numbers?

Our free digital asset savings projection tool shows cash losing value to inflation alongside rates you choose, and lets you stress-test the result with a crash. It is general education, not a forecast.
