RBA's Bullock: Oil Shock Puts Inflation Above August Track

Reserve Bank of Australia Governor Michele Bullock told the Senate Economics Legislation Committee on Wednesday that inflation will likely exceed the RBA's August forecasts, citing re-escalating Middle East conflict and higher global energy prices, hours before September quarter CPI data lands. The cash rate has risen 100 basis points this year, including a 25 basis point increase since the committee's June hearing. The RBA Board meets on November 2 and 3, with Bullock framing the decision as a genuine question of whether tightening to date is enough.

Context — Why Bullock's Oil Warning Matters Now

Bullock's August forecasts had inflation returning to around the midpoint of the 2% to 3% target only in late 2027. She said some of the upside risks the RBA flagged then have now materialised or are materialising, meaning the base case itself has moved. That is a material shift for a central bank that had been signalling patience.

The trigger is energy. Bullock said the Middle East conflict has re-escalated and global energy prices are now much higher than assumed in August. Higher oil and related prices will add materially to inflation directly, and again as businesses facing higher transport costs attempt to pass them through. She noted short-term inflation expectations are elevated, a signal that price pressure is feeding into how households and firms set prices and wages.

Bullock did not attribute the deterioration to energy alone. She pointed to the global AI boom and extreme weather as sources of upward pressure on technology and agricultural prices, broadening the inflation impulse beyond crude.

The backdrop is an RBA that has already tightened 100bp this year, with Bullock saying the full effects have yet to be felt. Household spending is moderating only gradually, while business investment is picking up strongly on data centres and renewable energy projects. Those two forces pull in opposite directions for demand, which is why the Board's November judgement is genuinely open rather than pre-committed.

Data — What the Numbers Show

Bullock's evidence set has four components. First, energy: global energy prices sit well above August assumptions, which the RBA says will add materially to inflation both directly and through transport cost pass-through. Second, the labour market: unemployment has risen a little more than expected, but Bullock said the market looks slightly tighter than the RBA had judged.

Third, inflation composition: Bullock cited elevated underlying inflation in areas that reflect domestic demand, distinguishing home-grown price pressure from imported energy costs. Fourth, productivity: weak productivity growth means the economy cannot grow strongly without adding to price pressures, a constraint she described as fundamental for Australia and for real spending power over the next few years.

The policy tally: 100bp of hikes this year, including the 25bp move since June. Housing prices have fallen in most capital cities but remain around 50% above early 2020 levels, and Bullock said the RBA does not target house prices.

Metric	Level cited by Bullock
Cash rate hikes this year	100bp
Increase since June hearing	25bp
Housing prices vs early 2020	~50% above
Target band	2% to 3%

The before-and-after is stark: in August, inflation returned to target midpoint in late 2027 on the RBA's own forecast. On Wednesday, Bullock said that track is now too optimistic.

Analysis — What It Means for Markets and Sectors

Bullock's framing is hawkish on three fronts. Saying inflation will exceed the August base case removes the RBA's own forecast as an argument against tightening. Asking openly whether current tightening is enough keeps November live. Saying the labour market is tighter than judged undercuts the dovish case that rising unemployment will do the disinflation work on its own.

The second-order effects run through energy and transport. Australian businesses facing higher fuel and freight costs either absorb them in margins or pass them on; Bullock's language points to pass-through. That keeps services and logistics inflation sticky even if goods disinflation continues, which is the composition problem she flagged in domestic-demand categories.

The counter-argument deserves weight. Bullock said the full effects of 100bp of hikes have yet to be felt, household spending is moderating, and business investment is picking up. If those lags bite harder than expected, the Board could hold in November and let the existing tightening work. Weak productivity, though, cuts the other way: it lowers the growth rate the economy can sustain without generating inflation.

Positioning follows the language. Bullock's comments support the Australian dollar and front-end yields, because a live November meeting raises the probability of another hike. The dovish trade — long bonds, short AUD — needs the quarterly trimmed mean to come in soft to survive.

Outlook — What to Watch Next

The decisive catalyst is today's September quarter CPI, specifically the trimmed mean. A firm print would likely push markets further toward pricing a November hike. The RBA Board meets on November 2 and 3, and Bullock said the Board will assess the data and the balance of risks then.

Watch the labour market data between now and the meeting for confirmation or contradiction of Bullock's tighter-than-judged view. Watch energy prices for whether the Middle East escalation continues to feed crude, since that is the channel she identified as the main new pressure. Watch short-term inflation expectations, which Bullock described as elevated, for signs they are anchoring or drifting.

No specific levels were given by the RBA, and none are asserted here. The conditionals are straightforward: firm core CPI plus elevated energy keeps November live; a soft core print plus moderating demand gives the Board room to hold.

Frequently Asked Questions

What does Bullock's warning mean for Australian mortgage holders?

Bullock said the cash rate is up 100bp this year, including 25bp since the June hearing, and that higher rates are difficult for households. She also said high inflation cannot be allowed to persist. If the November Board judges current tightening insufficient, another increase would add to variable mortgage repayments. Bullock acknowledged the household burden directly while arguing the alternative — entrenched inflation — carries its own cost.

Why does the RBA care about oil prices when Australia is not a major oil producer?

Bullock said higher oil and related prices add materially to inflation directly, and again as businesses facing higher transport costs try to pass them on. Australia imports refined fuel, so a global energy price rise raises input costs across transport, logistics and agriculture. She also flagged extreme weather as a source of pressure on agricultural prices, compounding the imported cost channel.

What is the trimmed mean and why does it decide the November meeting?

The trimmed mean is a core inflation measure that strips out the most volatile price moves, giving a cleaner read on underlying pressure. Bullock cited elevated underlying inflation in domestic-demand categories, which is exactly what the trimmed mean captures. A firm quarterly print would confirm her tighter-than-judged view and push markets toward a November hike; a soft print would support the case for holding.

Bottom Line

Bullock's oil-driven inflation warning leaves the November RBA meeting genuinely live, with today's trimmed mean as the deciding input.
