February CPI at 3.7%: Why This Is the Calm Before Australia's Inflation Storm
The Numbers Look Encouraging. They Shouldn’t.
On 25 March 2026, the Australian Bureau of Statistics released the monthly Consumer Price Index indicator for February. Headline CPI came in at 3.7% year-on-year, down a tenth of a percentage point from January’s 3.8%. The trimmed mean, the RBA’s preferred measure of underlying inflation, held steady at 3.3%.
On the surface, this looks like progress. Inflation ticking down, however slowly, in the right direction. Markets initially reacted positively. Some commentators suggested the data might give the RBA room to pause its hiking cycle.
They’re wrong. And the reason is timing.
The February data captures prices through the end of February 2026. The US-Iran conflict began on 28 February. The Strait of Hormuz effectively closed in early March. Petrol prices have since surged 50 cents per litre. None of that is in the February numbers.
What we’re looking at isn’t the inflation picture. It’s a photograph of the world before the storm hit.

What Drove February Inflation
The largest contributors to annual CPI in February were:
| Category | Annual Change | Contribution |
|---|---|---|
| Housing | +6.8% | Largest contributor |
| Food and non-alcoholic beverages | +3.1% | Second largest |
| Recreation and culture | +3.7% | Third largest |
| Insurance and financial services | +5.2% | Significant contributor |
| Transport | +1.9% | Moderate (pre-fuel spike) |
Housing inflation remains stubbornly high, driven by three components:
- New dwelling purchase costs (+4.8%): Construction costs have eased from their 2023 peaks but remain elevated due to labour shortages and material costs.
- Rents (+6.2%): The national rental vacancy rate sits around 1.3% (SQM Research), well below the 3% level considered balanced. With population growth outpacing new housing supply, rent inflation has minimal prospect of easing in the near term.
- Electricity (+9.1%): Despite government energy rebates reducing the headline figure, underlying wholesale electricity costs remain high, and the rebates are scheduled to wind down.
The Trimmed Mean Signal
The trimmed mean holding at 3.3% is the more concerning reading for the RBA. This measure strips out the most volatile items (top and bottom 15% of price changes) and reflects broad-based price pressures.
At 3.3%, trimmed mean inflation remains comfortably above the RBA’s 2-3% target band. It hasn’t been within the target since early 2022. The persistence of core inflation at these levels is precisely why the RBA raised rates at both its February and March 2026 meetings.
Why the Worst Is Ahead
The Fuel Price Shock
The single biggest driver of Australia’s inflation outlook over the next three to six months is fuel.
Since the February CPI reference period ended:
- Unleaded petrol has risen from approximately $1.69/L to $2.19/L nationally
- Diesel has risen from approximately $1.74/L to $2.28/L
- The Strait of Hormuz remains effectively closed
- CBA forecasts a “strong likelihood” of oil reaching US$120-150 per barrel
Westpac’s economics team estimates the March monthly CPI could rise by 1.0% in a single month, an extraordinary pace. Their preliminary estimate for the March quarter puts headline CPI at 1.2% quarter-on-quarter, lifting the annual rate from 3.6% to 3.9%.
But it doesn’t stop there. If the oil supply disruption persists into Q2, Westpac projects headline inflation could reach 5.5% year-on-year by mid-2026.
The Fuel Multiplier Effect
Fuel inflation doesn’t just show up in the transport component of CPI. It cascades through the entire economy:
Food prices: Almost all food in Australia travels by truck. Diesel cost increases flow through to farmgate-to-shelf logistics within 4-8 weeks. The food component of CPI, already at 3.1%, could accelerate to 4-5% by Q3 2026.
Services: Any business that involves travel (trades, healthcare, delivery services, hospitality supply chains) faces higher input costs. Services inflation, which the RBA watches closely because it reflects domestic demand, was already running at 5.0% annually.
New housing: Construction relies heavily on diesel-powered machinery and truck deliveries. The Housing Industry Association has flagged that sustained fuel increases could add $8,000-$15,000 to new home build costs.
The Wage-Price Dynamic
Australia’s Wage Price Index rose 3.5% in the year to December 2025. While this is below headline inflation (meaning real wages are falling), it’s above the rate the RBA considers consistent with its inflation target.
The Fair Work Commission’s Annual Wage Review, expected in June 2026, will be closely watched. If minimum and award wages receive a significant increase to compensate for higher living costs, it could entrench inflation further, creating the kind of wage-price spiral the RBA is trying to avoid.
What the RBA Is Thinking
The March Rate Decision
The RBA raised the cash rate by 25 basis points to 4.10% on 19 March 2026. In its statement, the Board noted:
- Inflation remains above target
- The labour market, while softening, is still relatively tight
- Global uncertainty from the Middle East conflict poses upside risks to inflation
- Household consumption has been resilient despite previous rate increases
The Board explicitly flagged that it was “prepared to take further action” if inflation did not continue to moderate.
The Forward Path
Markets are now pricing in at least two more rate increases in 2026, with the cash rate expected to reach 4.60% by mid-year. Some economists are more pessimistic.
The Nightly reported in March that if the Middle East conflict persists, variable mortgage rates could soar by another 100 basis points to levels above 7%, implying a cash rate of 5.10% or higher.
| Scenario | Expected Cash Rate | Timeline |
|---|---|---|
| Best case (Strait reopens, inflation peaks) | 4.10-4.35% | Holding or one more hike |
| Central case (conflict continues months) | 4.60% | Two more hikes by mid-2026 |
| Worst case (prolonged disruption) | 5.10%+ | Four more hikes through 2026 |
The RBA’s Dilemma
The challenge for the RBA is that rate hikes don’t fix supply-side inflation. Raising the cash rate doesn’t open the Strait of Hormuz. It doesn’t bring fuel prices down. It doesn’t increase housing supply.
What rate hikes do is reduce demand by making borrowing more expensive. This slows the economy, reduces consumer spending, and eventually puts downward pressure on prices, but at the cost of higher unemployment and potential recession.
Australia’s unemployment rate has already ticked up to 4.3% from 3.9% a year ago. If the RBA hikes aggressively to combat fuel-driven inflation, unemployment could push above 5%, triggering a broader economic downturn.
This is the stagflation scenario, rising prices and slowing growth simultaneously, that economists have been warning about since the conflict began.
How This Affects Different Australians
Mortgage Holders
The impact on mortgage holders is direct and quantifiable.
| Mortgage Size | Monthly Increase (3.85% to 4.10%) | Monthly Increase (3.85% to 4.60%) | Monthly Increase (3.85% to 5.10%) |
|---|---|---|---|
| $400,000 | +$57 | +$174 | +$293 |
| $600,000 | +$85 | +$261 | +$440 |
| $800,000 | +$114 | +$348 | +$587 |
| $1,000,000 | +$142 | +$435 | +$734 |
These figures assume a 30-year principal and interest loan on a variable rate. Add fuel and grocery inflation, and a household with a $600,000 mortgage could be paying $600-900 more per month in total living costs by mid-2026 compared to early February.
Renters
Renters face a double squeeze. Landlords with variable mortgages are passing on higher costs through rent increases (allowed at lease renewal in most states). At the same time, renters are paying more for fuel, groceries, and utilities.
National rents have risen 6.2% year-on-year according to the ABS. In some capital city markets, the increase is higher:
| City | Annual Rent Growth (Feb 2026) |
|---|---|
| Perth | +8.7% |
| Brisbane | +7.4% |
| Adelaide | +7.1% |
| Sydney | +6.8% |
| Melbourne | +4.9% |

Retirees
Retirees on fixed incomes are particularly vulnerable to inflation. While the Age Pension is indexed to CPI (adjusted in March and September each year), the adjustment lags actual price increases. Retirees drawing down superannuation also face the challenge of maintaining purchasing power while investment returns may be volatile.
The full Age Pension for a single person is $1,144.40 per fortnight as of March 2026. For a couple combined, it’s $1,725.20 per fortnight. These amounts don’t stretch far when petrol is $2.19/L and grocery prices are climbing.
Savers
There’s a silver lining for savers. Higher cash rates mean higher savings account and term deposit rates. The best high-interest savings accounts are now offering 5.0-5.5% per annum, and term deposits for 12 months are available at 4.8-5.2%.
However, with inflation at 3.7% (and potentially heading to 5.5%), real returns (after inflation) are modest at best and could turn negative if inflation accelerates faster than deposit rates.
What You Should Be Doing Now
1. Audit Your Household Budget
Map every dollar coming in and going out. Identify discretionary spending you can reduce. Focus on the big levers: subscriptions, dining out, entertainment, and non-essential purchases. Use the higher fuel and grocery costs as your baseline, not the prices from three months ago.
2. Stress-Test Your Mortgage
Ask your broker or use an online calculator to model repayments at 7% or higher. If you can’t comfortably meet those repayments plus higher living costs for six months, you need to take action now. Options include:
- Fixing a portion of your loan (provides certainty, though fixed rates have already risen)
- Extending your loan term (reduces monthly payments, increases total interest)
- Making extra repayments into your offset while rates are still below worst-case levels
- Refinancing to a more competitive lender
3. Build an Emergency Buffer
Financial planners generally recommend 3-6 months of essential expenses in an accessible savings account. In the current environment, err toward the higher end. This buffer protects against job loss, unexpected expenses, or a sustained period of higher costs.
4. Review Your Investment Strategy
If your portfolio is heavily weighted toward growth assets (shares, property), consider whether your risk profile still matches your timeline. Speak to a financial adviser about:
- Inflation-hedging assets (commodities, infrastructure, inflation-linked bonds)
- Defensive positioning (increasing cash or fixed income allocation)
- Tax-loss harvesting to offset gains in energy stocks against losses elsewhere
5. Lock In What You Can
Where you have flexibility to fix costs, do it:
- Energy plans: compare rates and lock in fixed-price plans before the next price reset
- Insurance: review policies at renewal rather than auto-renewing, as premiums are rising 5-10% annually
- Subscriptions and memberships: negotiate annual rates rather than monthly where possible
6. Talk to a Professional
This is not a normal inflation environment. The combination of geopolitical conflict, supply-side energy shocks, and an RBA hiking cycle creates complexity that generic advice can’t address. A mortgage broker can identify savings you might miss. A financial adviser can stress-test your portfolio against multiple scenarios. An accountant can help structure your affairs for tax efficiency in a high-inflation environment.
The Road Ahead
The February CPI reading of 3.7% will likely be remembered as the last relatively benign inflation print for some time. By the time the March data is published in late April, the fuel price surge will be fully reflected, and the number is likely to be significantly higher.
How long this lasts depends on factors largely outside Australia’s control: the duration of the Iran conflict, the reopening of the Strait of Hormuz, and the global oil supply response. What is within your control is how prepared you are.
The households that come through this period in the strongest position will be those that acted early: stress-tested their budgets, locked in what they could, built buffers, and sought professional advice before being forced to.
Inflation is a tax on the unprepared. Don’t wait for the storm to hit before you start building shelter.

Frequently Asked Questions
What was the Australian CPI inflation rate in February 2026?
The ABS monthly CPI indicator showed annual inflation of 3.7% in February 2026, down marginally from 3.8% in January. The trimmed mean (the RBA's preferred core inflation measure) held steady at 3.3%. Housing costs (+6.8%) remained the largest contributor to annual inflation.
Why do economists expect Australian inflation to rise sharply in 2026?
The February CPI data was collected before the full impact of the Iran conflict and Strait of Hormuz blockade hit fuel prices. Petrol prices have since risen approximately 50 cents per litre. Westpac estimates March CPI could rise 1.0% in a single month, with headline inflation potentially reaching 5.5% year-on-year by mid-2026, driven primarily by energy costs flowing through to transport, food, and services.
What is the RBA's inflation target in Australia?
The Reserve Bank of Australia targets inflation of 2-3% per year on average over time, measured by the Consumer Price Index. As of March 2026, both headline CPI (3.7%) and trimmed mean inflation (3.3%) remain above this target band, which is why the RBA has continued raising the cash rate.
How does inflation affect mortgage repayments in Australia?
When inflation stays above the RBA's 2-3% target, the RBA raises the cash rate to slow spending and reduce price pressures. Each 25 basis point increase adds roughly $85-95 per month to repayments on a $600,000 variable rate mortgage. The cash rate has risen from 3.85% to 4.10% since February 2026, with further increases expected.
What is the difference between headline CPI and trimmed mean inflation in Australia?
Headline CPI measures the total price change across all goods and services in the ABS basket. Trimmed mean strips out the most volatile price movements (the top and bottom 15%) to reveal underlying inflation trends. The RBA focuses on trimmed mean because it's less distorted by temporary spikes in items like fuel or fruit. In February 2026, headline CPI was 3.7% while trimmed mean was 3.3%.
What should Australian households do to prepare for higher inflation?
Key steps include reviewing and tightening household budgets, building an emergency cash buffer of 3-6 months' expenses, locking in fixed-price contracts where possible (energy, insurance), reviewing mortgage arrangements with a broker, and ensuring investment portfolios include inflation-hedging assets. Speaking with a qualified financial adviser can help tailor a strategy to your specific situation.
