Recent Australian inflation data and resilient economic activity have positioned a 25 basis point cash rate increase as the leading outcome for the Reserve Bank of Australia’s September 29 meeting, with market-implied odds at 58 percent versus 41 percent for no change. July CPI eased to 3.5 percent year-over-year while trimmed mean inflation held at 3.6 percent, remaining well above the 2–3 percent target, and stronger-than-expected Q2 GDP plus firm discretionary spending have reinforced upside risks. The RBA’s August statement emphasized vigilance against embedded inflation pressures and readiness to tighten further if needed, aligning with recent bank forecasts from NAB and others shifting toward a September move. Traders are monitoring pre-meeting labor, consumption, and housing indicators for any last signals before the decision.

The resolution source will be official information from the Reserve Bank of Australia, including the statement or release from its September 2026 meeting, scheduled for September 28-29, 2026, as listed on the official RBA calendar (https://www.rba.gov.au/schedules-events/calendar/?topics=monetary-policy-board). This market may resolve as soon as the statement or release of the Reserve Bank of Australia Monetary Policy Board resulting from its September 2026 meeting with relevant data is issued.
If the specified rate is defined by an upper and lower bound, the relevant change will be the change to the upper bound.
If the specified rate is changed to a level not expressed in the displayed options, the change will be rounded according to the following guidelines. Increases or decreases of less than 25 bps will be rounded to 25 bps (e.g. an increase or decrease of 10 bps would be considered to be an increase or decrease of 25 bps). Increases or decreases of greater than 25 bps will be rounded to the nearest 25 bps and will be rounded away from 0 in cases of equidistance (e.g., an increase or decrease of 37.5 bps would be considered to be an increase or decrease of 50 bps). Displayed options of "Increase" or "Decrease" will include policy rate increases or decreases of any size.
If the specified meeting is postponed to a date and time before the start of the next scheduled meeting, this market will resolve based on the outcome of that postponed meeting.
If the specified meeting is cancelled, or postponed such that no decision is announced by the start of the next scheduled meeting, this market will resolve to the "No Change" bracket. Emergency changes to the specified rate not resulting from the specified meeting will not be considered.
