RBA's Hunter Flags Fifth Hike as Oil Shock Spreads

The Reserve Bank of Australia has not finished tightening, according to its own forecasting chief, and traders are pricing a fifth increase for November 3. Sarah Hunter, Assistant Governor for Economics, told Nine Network's 60 Minutes in an interview broadcast Sunday evening Australian time that four hikes this year have left the bank "not quite yet" at a sufficiently restrictive setting. The cash rate sits at 4.6%, a 15-year high. Third-quarter CPI lands Wednesday, with trimmed mean inflation expected at 3.6%, broadly unchanged from the prior quarter.

Context — Why RBA Hawkishness Matters Now

Hunter's comments follow a material shift in the bank's own language. Deputy Governor Andrew Hauser said on Wednesday that the inflation outlook is materially worse than the bank assessed in August. That single admission reset market expectations for November and pushed the board's reaction function back toward tightening.

What changed is the composition of inflation, not just its level. Hunter pointed to higher oil prices tied to the ongoing US-Iran war becoming embedded in some supply chains, with more pass-through expected. That matters because energy shocks that migrate from fuel into broader input costs tend to be stickier than the headline spike that starts them.

The August assessment the RBA has now superseded is the comparable the bank itself provides. Four hikes this year took the cash rate to 4.6%, yet the bank says the job is unfinished — meaning the tightening delivered so far has not produced the disinflation the board wanted.

Hunter also addressed housing. Falling Australian property prices are not, so far, generating systemic financial stress, she said. That removes what would otherwise be the most obvious argument for pausing.

The policy backdrop is therefore a central bank that sees an energy-driven cost shock spreading, an inflation outlook it has already downgraded, and a housing market it does not regard as a constraint.

Data — What the Numbers Show

The hard figures are narrow. The cash rate stands at 4.6%, reached after the RBA lifted rates in late September. That is the highest level in 15 years. Four increases have been delivered in 2026.

The next decision is scheduled for November 3. Before it, third-quarter consumer price data are released on Wednesday, with the trimmed mean measure expected at 3.6%, broadly in line with the previous quarter.

Metric	Level
RBA cash rate	4.6% (15-year high)
Hikes delivered in 2026	Four
Q3 trimmed mean CPI (expected)	3.6%
Prior quarter trimmed mean	Broadly similar
Next RBA meeting	November 3

A 3.6% trimmed mean would be unchanged in substance from the prior quarter — a flat print at a level the bank has already called insufficient. The comparison matters: an in-line result does not represent progress, it represents persistence.

The same day the CPI data land, Governor Michele Bullock and other policymakers appear before parliament. That gives the board a second platform to shape expectations within hours of the inflation print.

On the currency side, the rate differential story favours the Australian dollar at the margin, and short-dated Australian government bond yields are likely to stay elevated. A hike priced for November keeps front-end yields anchored above where they would sit under a hold.

Analysis — What It Means for Markets and Sectors

The clearest transmission is through the front end of the curve. Short-dated Australian government bond yields stay elevated as long as a November hike remains the base case, and Wednesday's CPI is the single input that can move that base case.

Oil is the swing variable. Renewed escalation in the US-Iran war that lifts crude would deepen the RBA's concern about second-round effects and raise the risk of tightening beyond November. A sustained easing in crude would give the board more room to signal a pause after its next move. Neither outcome is a forecast — both are conditional on the conflict's path.

Equities exposure is concentrated in rate-sensitive domestic names. Property-linked stocks and consumer discretionary names on the ASX remain exposed to a higher-for-longer policy path. Falling house prices, which Hunter said are not yet causing systemic stress, pressure the listed property complex regardless of whether the RBA hikes again.

The counter-argument deserves weight. If Wednesday's trimmed mean prints below 3.6%, the case for November weakens materially, and a board that has already delivered four hikes may prefer to assess the lagged effect of those moves before adding a fifth. Hunter declined to pre-empt the decision, which leaves that door open.

Positioning reflects the tension. Markets have leaned further toward a November hike since Hauser's remarks, but the flow is event-driven rather than conviction-driven — desks are positioned for the CPI print, not for a full tightening cycle.

Outlook — What to Watch Next

Wednesday is the pivot. Third-quarter CPI, with trimmed mean expected at 3.6%, lands the same day Bullock and colleagues appear before parliament. A print at or above expectations, combined with the oil pass-through Hunter described, leaves a November 3 hike as the market's base case.

Watch the crude price as the second catalyst. Escalation in the US-Iran war that pushes oil higher reinforces the second-round effects argument and raises the risk of tightening beyond November. A sustained decline does the opposite.

On the currency, the Australian dollar stays supported at the margin on rate differentials while a hike is priced. Short-dated Australian government bond yields are the cleanest read on how firmly the market holds that view. There is no level the report names, so the CPI figure itself is the threshold that matters.

Frequently Asked Questions

What does the RBA's November 3 meeting mean for the Australian dollar?

A hike priced for November supports the Australian dollar at the margin through rate differentials — higher local rates attract yield-seeking flows. Hunter's remarks, and Hauser's before them, have already pushed markets toward that outcome. If Wednesday's trimmed mean CPI comes in below the expected 3.6%, that support weakens quickly, because the differential argument depends on the hike actually being delivered.

Why is the US-Iran war relevant to Australian inflation?

Hunter said higher oil prices linked to the conflict are becoming embedded in some supply chains, with more pass-through expected. That matters because the RBA's concern is second-round effects: energy costs migrating from fuel into the broader cost base. Once that happens, inflation becomes more persistent and harder to reverse with a single rate move, which is why the war sits at the centre of the bank's November calculus.

Which ASX sectors are most exposed to a higher-for-longer RBA path?

Property-linked stocks and consumer discretionary names carry the clearest exposure. Property names face both higher financing costs and falling house prices, which Hunter said are not yet causing systemic stress. Consumer discretionary companies depend on household spending that a 4.6% cash rate constrains. Both groups are sensitive to whether the board delivers a fifth hike or signals a pause after November.

Bottom Line

Hunter's "not quite yet" keeps a November 3 hike as the base case, with Wednesday's 3.6% trimmed mean print and crude's path the two variables that decide it.
