Inflation erodes the purchasing power of your money over time. Understanding how it works helps you make smarter financial decisions about saving, investing, and protecting your wealth in Australia.
Key Takeaways
- RBA targets 2-3% annual inflation for a healthy economy
- Australian inflation peaked at 7.8% in December 2022, now moderating
- At 3% inflation, $100 today will only buy $74 worth of goods in 10 years
- Cash in savings accounts typically loses purchasing power after tax and inflation
- Investments in shares, property, and inflation-linked bonds can hedge against inflation
What is Inflation?
Inflation is the rate at which the general level of prices for goods and services rises over time, causing the purchasing power of money to fall. In simple terms:
If inflation is 3% annually: Something that costs $100 today will cost approximately $103 next year. Your $100 will only buy what $97 bought last year.
How Inflation is Measured
In Australia, the Australian Bureau of Statistics (ABS) measures inflation through the Consumer Price Index (CPI):
CPI Basket Components
- Housing (23%)
- Food and non-alcoholic beverages (17%)
- Transport (11%)
- Recreation and culture (9%)
- Health (7%)
- Insurance and financial services (6%)
- Other goods and services (27%)
CPI Measurement
- Released quarterly by ABS
- Measures 87 expenditure classes
- Tracks ~100,000 price points
- Weighted by household spending
- Covers 8 capital cities
- Base period adjusted periodically
Australian Inflation History
| Period | Annual CPI | Key Factors |
|---|---|---|
| 2019 | 1.8% | Pre-pandemic low inflation |
| 2020 | 0.9% | COVID-19 economic downturn |
| 2021 | 3.5% | Post-lockdown recovery begins |
| 2022 | 6.6% | Supply chains, Ukraine war, energy prices |
| Q4 2022 (Peak) | 7.8% | 32-year high |
| 2023 | 4.1% | RBA rate hikes taking effect |
| 2024 | ~3.5% | Continuing moderation |
| 2025 (Forecast) | ~2.5-3% | Approaching RBA target |
What Causes Inflation?
Demand-Pull Inflation
When demand for goods and services exceeds supply, prices rise:
- Economic growth: More jobs = more spending power
- Government stimulus: Direct payments boost demand
- Low interest rates: Cheaper borrowing = more spending
- Population growth: More people competing for goods
Cost-Push Inflation
When production costs increase, businesses pass costs to consumers:
- Rising wages: Higher labor costs
- Energy prices: Electricity, fuel, gas
- Supply chain disruptions: Shipping costs, shortages
- Currency depreciation: Imports become more expensive
- Natural disasters: Crop failures, infrastructure damage
Built-In Inflation
Expectations of future inflation become self-fulfilling:
The Inflation Spiral
- Workers expect prices to rise, demand higher wages
- Businesses face higher labor costs
- Businesses raise prices to maintain margins
- Prices rise, confirming expectations
- Cycle repeats...
How the RBA Controls Inflation
The Reserve Bank of Australia uses monetary policy to keep inflation within its 2-3% target band:
Interest Rate Tool
| Action | When Used | Effect on Inflation | Impact on You |
|---|---|---|---|
| Raise Cash Rate | Inflation too high | Decreases inflation | Higher mortgage rates, less spending |
| Lower Cash Rate | Inflation too low / recession | Increases inflation | Lower mortgage rates, more spending |
| Hold Rate | Inflation in target range | Maintains stability | Predictability in planning |
RBA Cash Rate History
Recent Rate Movements
- March 2020: 0.10% (COVID emergency rate)
- May 2022: First increase to 0.35%
- November 2023: 4.35% (peak of cycle)
- January 2025: Rate decisions ongoing based on inflation data
How Inflation Affects You
Impact on Savings
| Starting Amount | After 5 Years | After 10 Years | After 20 Years |
|---|---|---|---|
| At 2% inflation (Real purchasing power of $100,000) | |||
| $100,000 | $90,573 | $82,035 | $67,297 |
| At 3% inflation | |||
| $100,000 | $86,261 | $74,409 | $55,368 |
| At 5% inflation | |||
| $100,000 | $78,353 | $61,391 | $37,689 |
This shows what your $100,000 could buy in today's dollars after inflation.
Real Return Matters
If your savings account earns 4% and inflation is 3%, your real return is only 1%. After tax, you may actually be going backwards. This is why holding too much cash long-term can be costly.
Impact on Different Groups
Inflation Hurts:
- Cash savers: Money loses purchasing power
- Fixed income earners: Pensions, fixed salaries erode
- Renters: Rents typically rise with inflation
- Bond holders: Fixed interest payments worth less
- Low-income households: Spend more on essentials that rise fastest
Inflation Helps:
- Property owners: Asset values tend to rise
- Borrowers: Debt becomes easier to repay
- Share investors: Company revenues rise nominally
- Workers with wage growth: If wages exceed inflation
- Government: Tax revenue increases, debt easier to service
Protecting Against Inflation
Investment Strategies
| Asset Class | Inflation Protection | Risk Level | How It Helps |
|---|---|---|---|
| Shares/Equities | Good | High | Companies raise prices, revenues grow |
| Property | Good | Medium-High | Property values and rents rise |
| Inflation-Linked Bonds | Excellent | Low | Payments adjust with CPI |
| Gold/Commodities | Moderate | High | Traditional inflation hedge |
| Cash/Term Deposits | Poor | Low | Often loses to inflation after tax |
| Fixed Rate Bonds | Poor | Low-Medium | Fixed payments erode in value |
Practical Tips
Investments

- Keep minimal emergency cash, invest the rest
- Consider inflation-linked ETFs
- Review investments annually
Career & Income

Property
- Fixed rate loans lock in costs
- Property typically appreciates with inflation
- Rental income can be indexed
- Mortgage debt devalues over time
Spending
- Buy quality items that last
- Pre-purchase big items before price rises
- Review subscriptions annually
- Compare prices regularly
Inflation vs Deflation
While inflation means rising prices, deflation (falling prices) isn't necessarily better:
| Aspect | Inflation (High) | Target Inflation (2-3%) | Deflation |
|---|---|---|---|
| Purchasing Power | Falls rapidly | Falls slowly | Rises |
| Debt | Easier to repay | Manageable | Harder to repay |
| Consumer Spending | Spend now (prices rising) | Normal behavior | Delay purchases |
| Business Investment | Uncertain | Healthy | Reduced |
| Employment | Initial boost, then uncertainty | Stable | Job losses likely |
Why 2-3% is the Target
Low, stable inflation encourages spending (no point waiting for lower prices), supports employment, makes debt manageable, and gives the RBA room to cut rates if needed. Zero inflation or deflation can trigger economic stagnation.
Understanding Real Returns
Real vs Nominal Returns
Real Return Formula
Real Return ≈ Nominal Return - Inflation
*Before tax. After tax, the real return may be negative.
Frequently Asked Questions
Is some inflation good for the economy?
Yes, moderate inflation (2-3%) is considered healthy. It encourages spending over hoarding cash, supports employment, helps debtors gradually repay loans, and gives central banks room to cut rates during downturns. Zero or negative inflation (deflation) can be more harmful than moderate inflation.
Why does the price of groceries seem to rise faster than official inflation?
The CPI measures a broad basket of goods, while you may notice price changes in items you buy frequently. Food, fuel, and rent are highly visible expenses. Also, package sizes sometimes shrink ("shrinkflation") while prices stay the same, which isn't always captured in headline inflation figures.
How does inflation affect my mortgage?
Inflation can work in your favor as a borrower. Your fixed debt amount becomes worth less in real terms over time, while your wages and property value typically rise. However, the RBA raises interest rates to fight inflation, which increases your mortgage payments on variable rates.
Should I pay off debt or invest during high inflation?
Generally, if your after-tax investment return exceeds your after-tax debt interest rate, investing may be better mathematically. During high inflation, debt becomes cheaper in real terms to repay. However, paying down high-interest debt (credit cards, personal loans) usually makes sense regardless of inflation.
