How inflation affects your money in Australia

What is inflation and how does it compound?

Inflation is the rate at which the general price level of goods and services rises over time — which is the same as saying the purchasing power of your money falls. At 3.5% inflation, $100 today buys the same as $96.62 next year. Over 10 years, that $100 buys only $71 worth of goods. Crucially, inflation compounds: each year's price rise is applied to prices already elevated by prior years. A sustained 3.5% rate over 20 years cuts purchasing power nearly in half — from $100 to $50.

Australia's inflation history and the RBA target

Australia's Reserve Bank targets CPI inflation of 2–3% per year over the medium term — a range designed to support economic growth without significantly eroding savings. From 1993 to 2019, Australian CPI averaged around 2.5% p.a. During 2021–2023, a combination of supply chain disruptions, energy price spikes, and stimulus spending pushed CPI to a peak of 7.8% in December 2022. Inflation has since moderated back toward 3–3.5%, but the episode highlighted how quickly prolonged high inflation compounds.

How inflation silently erodes savings

If your savings account pays 2% interest but inflation runs at 3.5%, your real (inflation-adjusted) return is −1.5% per year. Your balance grows in nominal terms, but you can buy less with it each year. This is why Australian financial advisers emphasise real returns — returns above inflation. Cash held in a low-rate account loses purchasing power every year. Even a HISA at 5% only generates a real return of ~1.5–2% at current inflation rates, which is why long-term wealth building typically requires higher-returning assets.

Protecting your purchasing power in Australia

Historically, real assets have been the most effective hedge against inflation in Australia. ASX shares have returned approximately 9–10% p.a. total before tax — well above the long-run 2.5–3% inflation rate. Residential property has also outpaced inflation in most Australian capital cities over the long term. Within fixed income, inflation-linked bonds (like Australian Government Treasury Indexed Bonds) adjust their principal with CPI. Super funds with growth allocations also tend to outpace inflation over long horizons, which is why Australia's compulsory super system is designed to run for decades.

Frequently asked questions

What is the current inflation rate in Australia?
As of mid-2025, Australian CPI inflation is approximately 3–3.5% annually, down from a peak of 7.8% in December 2022. The RBA's target band is 2–3% over the medium term. The ABS publishes quarterly CPI data, which the RBA uses to guide interest rate decisions. The trimmed mean (which strips out volatile price changes) is a commonly used measure of underlying inflation and typically sits slightly below or above the headline CPI figure.
What does the RBA's 2–3% inflation target mean for my savings?
At 2.5% inflation — the midpoint of the RBA target — $100,000 in cash loses around $2,500 in real purchasing power each year. Over 10 years it buys only $78,100 worth of goods in today's money. This is why financial advisers consistently encourage Australians not to hold excessive cash long-term. The target also means that a savings account paying less than 2.5% actually loses real value. Current HISAs at 4.5–5.5% provide a positive real return at current inflation, but this is not guaranteed to persist.
How does inflation affect superannuation?
Your super fund's nominal return needs to exceed inflation to grow your real retirement wealth. Most Australian super funds publish a return target above CPI — for example, 'CPI + 3.5%' or 'CPI + 4%'. A balanced fund returning 7% in a 3% inflation environment is growing your real purchasing power at about 4% p.a. The longer your super compounds above inflation, the more comfortable your retirement. Conversely, if inflation is high and returns are low — a 'stagflationary' environment — super balances can stagnate in real terms.
Should I worry about inflation if my HISA pays 5%?
At current inflation of ~3–3.5%, a 5% HISA provides a real return of roughly 1.5–2% per year — your purchasing power is growing, but slowly. For short-term goals (emergency fund, house deposit within 2–3 years), a HISA is appropriate even with modest real returns. For long-term goals (retirement, 10+ years), relying solely on cash means accepting very slow real growth. The concern is not a loss — it is the opportunity cost of not investing in higher-returning assets.
What assets protect against inflation in Australia?
Equities (ASX shares and diversified ETFs) have historically been the strongest long-run inflation hedge, with real returns of ~6–7% p.a. over decades. Residential property in Australian capital cities has also outpaced inflation over long periods, though with much higher entry costs and lower liquidity. Inflation-linked bonds adjust their face value with CPI and guarantee a real return. Commodities (gold, oil) can hedge inflation in specific periods but are volatile. Cash and fixed-rate bonds tend to underperform during inflationary periods.
How is Australian inflation measured?
The Australian Bureau of Statistics (ABS) publishes the Consumer Price Index (CPI) quarterly. It tracks price changes across a representative basket of goods and services — housing, food, transport, healthcare, education, clothing, recreation. The basket is reweighted periodically to reflect spending patterns. The RBA also monitors the 'trimmed mean' CPI (excluding the top and bottom 15% of price changes) as a measure of underlying inflation that strips out volatile one-off movements.
