- Policy decision: The RBA raised the cash rate target by 25 basis points to 4.60% on 29 September. The decision was unanimous.
- Rate cycle: This was the fourth increase of 2026, taking cumulative tightening this year to one percentage point and lifting the cash rate to its highest level in around 15 years.
- Inflation backdrop: The latest available CPI data showed annual headline inflation at 3.5% in July and trimmed mean inflation at 3.6%, above the RBA’s 2% to 3% target range.
- RBA message: Policymakers said some upside inflation risks are materialising and that the cash rate could be increased further if needed.
- Market connection: The Australian dollar briefly strengthened after the decision but the move was limited because markets had already priced in a high probability of a rate increase.
- ICM relevance: The policy shift is directly relevant to AUD currency pairs, including AUD/USD, AUD/JPY, AUD/CHF, AUD/NZD, EUR/AUD and GBP/AUD.
Australia’s central bank raised its cash rate target from 4.35% to 4.60% at its September meeting, extending a tightening cycle that has already added a full percentage point to the policy rate this year. The Reserve Bank of Australia said the decision reflected stronger-than-expected inflation and signs that some of the upside risks identified earlier in the year are now materialising.
The Board’s statement placed particular emphasis on elevated global energy prices, domestic capacity pressures and weak productivity growth. It also noted that firms are reporting higher costs and, in some cases, are already raising prices or planning to do so.
The September move was widely anticipated by markets, which helps explain the relatively contained immediate reaction across Australian assets. The more important question for markets is now whether 4.60% represents the peak of the current cycle or whether persistent inflation will require another increase.
The latest complete inflation release available before the September meeting showed Australia’s Consumer Price Index rising 3.5% over the year to July. Trimmed mean inflation, a measure closely watched for underlying price pressure, was 3.6%.
Both measures remain above the RBA’s 2% to 3% inflation target. The central bank said recent inflation outcomes had been stronger than expected at its previous meeting and highlighted the risk that higher fuel costs could spread into the prices of other goods and services.
The RBA’s concern is therefore broader than the direct effect of energy prices. If businesses increasingly pass higher transport, production and input costs through to consumers, an external energy shock can become more persistent within domestic inflation. Policymakers said they remain focused on preventing high inflation from becoming embedded.
The RBA said global oil supply disruptions are maintaining upward pressure on energy prices and inflation. It also pointed to continued domestic capacity pressures, while weak productivity growth is constraining the economy’s potential growth rate.
This creates a difficult policy balance. Higher interest rates are intended to keep aggregate demand subdued enough to reduce inflation pressure, but the economy is already showing signs of slowing. The RBA noted that consumer spending growth is easing, housing prices have fallen in most capital cities and new housing loans have declined noticeably.
At the same time, other parts of the economy remain resilient. Business investment and business debt are growing strongly, while Australia’s major trading partners have performed better than the RBA had expected. The central bank said global AI-related investment has partly offset the negative economic effects of the Middle East conflict.
Australian household spending was flat in August after a strong 1.1% monthly increase in July, according to data released on the same day as the RBA decision. Consumers reduced spending in several categories while spending more on fuel.
Even with the flat monthly result, annual household spending growth remained strong at 6.8%. That resilience helps explain why policymakers continue to focus on inflation rather than treating softer housing conditions or isolated signs of weaker consumption as sufficient reasons to pause the tightening cycle.
The next major domestic inflation release is due on 30 September and covers August. It will provide markets with another important test of whether underlying price pressure is stabilising or remaining persistent after the latest rate increase.
The Australian dollar rose briefly after the RBA announcement before giving back much of the initial move. Reuters reported AUD/USD around 0.7014 after the decision, reflecting the fact that investors had already positioned heavily for a 25 basis point increase.
For currency markets, the policy decision matters through relative interest-rate expectations as well as Australia’s domestic outlook. If expectations for Australian rates change relative to those for the United States, Japan, New Zealand, Switzerland or Europe, those shifts can influence AUD pairs even when the RBA’s immediate decision is largely anticipated.
The RBA has not committed to another increase. Instead, it said future decisions will remain dependent on incoming data and its evolving assessment of the outlook and risks. This keeps inflation, labour-market conditions, household demand, energy prices and global financial conditions central to the AUD outlook.

- AUD/USD and other AUD crosses as markets reassess the expected peak in Australian interest rates.
- Global oil and fuel prices, given the RBA’s concern about energy-related inflation passing through to other prices.
- Household spending and housing indicators for evidence of how higher borrowing costs are affecting domestic demand.
- Labour-market conditions after recent signs of easing.
- Future RBA communication for any change in the balance between inflation risks and slowing economic activity.
