Australia’s Q2 Consumer Price Index (CPI) data is scheduled for release on Wednesday, 30 July, at 11.30 am Sydney time. The trimmed mean, a core inflation measure, is anticipated to stay stable quarter over quarter, with a predicted year-over-year decrease to 2.7%. If this decrease does not occur, the Reserve Bank of Australia (RBA) may maintain its current policy stance at the August meeting. The RBA’s potential target for the trimmed mean is 2.6% year over year, equating to approximately 0.55% quarter over quarter.
According to the Commonwealth Bank of Australia, the headline CPI is expected to rise by 0.8% quarter over quarter in Q2 25, leading to an annual rate drop to 2.2% year over year. The more pertinent trimmed mean CPI is forecast to increase by 0.7% quarter over quarter, resulting in a marginal annual rate dip to 2.8%. Depending on rounding, this may appear as 0.7% quarter over quarter and 2.7% year over year.
Anticipated Rate Cuts
There is anticipation that the RBA might implement a 25-basis point rate cut in August as the trimmed mean inflation continues to moderate, with another cut expected in November. Additionally, there is a risk of an extra cut in early 2026.
We see the upcoming Australian inflation data as the most significant event for the market this quarter, directly influencing the Reserve Bank’s August 6th decision. The figures will provide a critical update on whether price pressures are genuinely easing towards the central bank’s target. Derivative traders should therefore brace for heightened volatility around this release.
The key figure to watch is the trimmed mean inflation rate, which the market expects to dip to around 2.7% year-over-year. This would be a substantial slowdown from the 4.0% annual pace recorded in the first quarter of 2024. A number at or below this forecast would signal that the restrictive policy is working effectively.
Market Sentiment And Forecasts
One major bank’s forecast for a rate cut in August stands in stark contrast to broader market sentiment. According to the ASX RBA Rate Tracker, traders are currently pricing in less than a 15% chance of a cut, making the bank’s view a significant outlier. This disagreement means any surprisingly low inflation print could force a rapid and aggressive repricing in interest rate markets.
Given this setup, we believe implied volatility in Australian dollar options and interest rate futures will be elevated. Traders should anticipate sharp price swings in the currency and bond markets immediately following the data release on Wednesday. Preparing for a binary outcome is more important than committing to a single direction beforehand.
Historically, the central bank has held a target inflation band of 2-3%. With the current cash rate at a restrictive 4.35%, any confirmation that inflation is confidently returning to this band gives policymakers a clear reason to consider easing. A weaker-than-expected number would likely send the Australian dollar lower and bond prices higher as the market rapidly prices in a greater chance of a near-term cut.
Therefore, positioning for a market surprise could be a prudent strategy. Options that profit from a significant move, rather than a specific direction, might be useful for navigating the event. If the trimmed mean figure is much higher than expected, the market will have to quickly unwind the few rate cut bets that exist and could even begin to contemplate another hike.
