RBA's Hauser Flags Hot Q3 Trimmed Mean, Hike Odds for 3 November

Reserve Bank of Australia Deputy Governor Andrew Hauser said the September-quarter trimmed mean looks set to print above the central bank's own expectation, a steer delivered one week before the Australian Bureau of Statistics publishes the official CPI data on 28 October. The cash rate sits at 4.60% after the Board lifted it on 29 September. The RBA's next decision lands at 2.30pm Sydney time on 3 November, or 03:30 GMT and 22:30 ET on 2 November, published alongside updated staff forecasts.

Context — why an RBA steer a week before CPI matters

Hauser spoke at Citi's Australia and New Zealand Investment Conference in Sydney. His trimmed mean remark is the second leg of a message he had already begun building, having said earlier that the inflation outlook looks worse than forecast. Central banks rarely front-run their own statistics office. Doing so a week out converts a data release into something closer to a confirmation exercise.

The trimmed mean strips out the largest price rises and falls each quarter to give a cleaner read on underlying inflation. It is the measure the RBA watches most closely, which is why a steer on this series carries more weight than a steer on the headline number would.

Hauser also said capacity pressures in the economy are more elevated than the RBA had anticipated. That speaks to demand still running further ahead of supply than policymakers assumed, which matters because it is the demand-side story the RBA can actually address with the cash rate.

The catalyst chain runs in one direction. A hotter trimmed mean removes the main argument for standing pat. Tighter capacity than assumed removes the second. Hauser's framing leaves the softer September labour report as the only meaningful counterweight, and he described it himself as clearly a little weaker than expected rather than as a turning point.

The cash rate at 4.60% is the reference level for everything that follows. Australian short-end yields and the Australian dollar are the two instruments that price RBA expectations most directly, and both respond to shifts in the hike-versus-hold balance.

Data — what Hauser actually said, and what it changes

Hauser's inflation remark is directional rather than numerical. He said the quarterly trimmed mean looks like it will be higher than the RBA expected, without giving a figure. The official print arrives on 28 October. Until then, the market is working from his characterization, not from a number.

On capacity, the same pattern holds. Pressures are more elevated than anticipated, which is a statement about the gap between the RBA's model and the economy, not a level. The practical read is that the RBA's own assumptions were too loose.

On supply shocks, Hauser said the RBA has to respond to them in order to keep inflation expectations anchored. Central banks typically look through supply-driven price rises on the basis that they fade. His comment suggests the RBA sees less room to do that after a long period of high inflation. The RBA has previously pointed to the Middle East conflict and its effect on oil prices as a supply-side pressure.

Signal	Hauser's steer	Implication
Q3 trimmed mean	Higher than RBA expected	Upside risk to 28 October CPI
Capacity pressures	More elevated than assumed	Less spare capacity than modelled
Supply shocks	Must be answered	Oil passes through to rate pricing
September labour	A little weaker than expected	Partial offset only

He added that monetary policy cannot target current inflation because it works with a lag, but stressed that current inflation is not therefore irrelevant, since persistent price rises can feed into expectations.

Analysis — where the repricing lands

A trimmed mean beat on 28 October would leave a further rate rise firmly on the table for 3 November. That is the direct channel, and it runs through the Australian short end first. Two-year Australian yields are the cleanest expression of a shift in near-term RBA expectations, and they reprice ahead of the cash rate itself.

The currency channel follows. Higher hike pricing tends to support the Australian dollar, particularly against currencies whose central banks are not moving in the same direction. The report does not name a currency pair, so the read stays at the level of direction rather than a specific cross.

The oil channel is the less obvious one. If the RBA is less inclined to look through energy-driven price rises while expectations are at risk, then crude becomes a more direct input into Australian rate pricing than it would be under a look-through regime. That links energy headlines to Australian front-end rates in a way that is normally absent.

The counter-argument deserves weight. September labour data came in a little weaker than expected, and Hauser said that while unemployment remains quite low, conditions are easing. A softening jobs market is the standard argument for patience, and doves will use it. Hauser's own framing suggests it is not enough on its own to keep the Board on hold, but it does mean the November decision is not a formality.

Positioning follows the same logic. Hawkish steer plus a CPI print a week away plus a decision five days after that gives traders a compressed window to express a view. Flow into Australian front-end shorts and long AUD positioning is the natural expression, and the risk is a CPI miss that unwinds it quickly.

Outlook — what to watch next

Two dates carry the weight. September-quarter CPI lands on 28 October. The RBA decides on 2 and 3 November, with the announcement at 2.30pm Sydney time on 3 November, or 03:30 GMT and 22:30 ET on 2 November, and updated staff forecasts published alongside it.

The trigger to watch is the trimmed mean relative to the RBA's expectation, since that is the specific series Hauser flagged. A print above expectation keeps a further rate rise firmly on the table. A print at or below expectation removes the primary justification for the steer and shifts attention back to the labour market.

The second trigger is the forecasts released with the November decision. Those numbers show whether the RBA has formally marked up its own inflation path or is still treating the overshoot as noise. A marked-up path is the durable signal; a single hot print is not.

No specific levels are named in the report, so the levels to watch are whatever the 28 October release establishes against the RBA's stated expectation. That comparison, not an absolute number, is what moves pricing.

Frequently Asked Questions

What does the trimmed mean measure and why does the RBA watch it?

The trimmed mean strips out the largest price rises and falls each quarter to give a clearer read on underlying inflation. It is the measure the RBA watches most closely, which is why Hauser's steer on this series carries more weight than a comment on the headline CPI would. A headline number can be distorted by a handful of volatile items; the trimmed mean is designed to filter those out.

What would a hot Q3 CPI print mean for Australian mortgage holders?

It would leave a further rate rise firmly on the table for 3 November, per Hauser's framing. The cash rate currently sits at 4.60% after the 29 September increase. A move from there would lift variable mortgage rates that track the cash rate. The report does not quantify the size of any potential move, and Hauser gave no figure for the trimmed mean itself.
