RBA Signals Caution, CPI Prints Below Forecast
The session came hot on the heels of the RBA raising the official cash rate by 25 basis points to 4.60%, its fourth increase of 2026 and the highest level in 15 years. While the move itself was expected, it was the tone from Governor Michele Bullock that markets latched onto. Bullock expressed a cautious “hope” that the latest hike would prove sufficient to bring inflation back within the RBA’s 2-3% target band, without committing to a formal pause.

The follow-through this morning saw August CPI data come in at 4.0% year-on-year, marginally below the 4.1% consensus estimate. The monthly trimmed mean, the RBA’s preferred measure of underlying inflation, rose just 0.2% month-on-month against a 0.3% expectation.
That combination was enough to push three-year Australian government bond yields down to approximately 4.88%, easing the discount rate pressure that has weighed on growth and rate-sensitive equities throughout the year. Traders moved quickly to reduce the probability of a November rate hike in overnight index swap markets.
Rate-Sensitive Sectors Lead the Rebound
Charter Hall Group’s 6.43% gain was the clearest expression of the rate-relief trade. A-REITs have been among the most punished segments of the ASX in recent months, as rising rates compressed property valuations and increased financing costs across leveraged real estate platforms.
The easing in bond yields from highs provided immediate relief, and CHC was well-positioned to benefit given its strong operational fundamentals entering the new fiscal year. REA Group’s gain was similarly tied to the rate narrative, amplified by a broker upgrade from Bell Potter to a buy-leaning stance.
What To Watch Into Q4
Returning to positive territory YTD is a strong start for bulls, but the index’s path from here will remain heavily dependent on the RBA’s next move and the durability of the inflation softening trend. The geopolitical backdrop, and the implications on oil prices and inflation have been keenly felt by markets since the conflict between the US and Iran first began, with the earlier easing of pressure coming as it looked like the Strait of Hormuz would reopen.
That deal has since been followed up by an increase of tensions which is only just beginning to see talks reconvene. Bond yields, and the weight of 5%+ US treasuries have seen equity markets take pause, and an easing of pressure may be needed if the index is to maintain momentum into year end.
If the August CPI print proves to be the beginning of a sustained disinflationary sequence, the case for a genuine rate pause, and a re-rating of growth and yield-sensitive equities, strengthens considerably. The final session of September offered the ASX 200 a much-needed reset, but whether it marks a durable turning point or simply a tactical bounce within a broader corrective trend will become clearer as further data filters through.
The historically challenging September can now be consigned to the rear view mirror, and whilst a 3.16% decline is not what bulls would have been looking for, it could have been worse, with the zone around 8670 twice acting as support for some relief. The 200 day SMA at 8825 will be a meaningful test for bulls to shift momentum, and with the index up 1.43% week to date, with two sessions remaining, that test could be on the cards.
