There is a particular kind of market reflex that returns every time a barrel of oil moves. A headline crosses, prices spike, energy stocks jump, miners wobble, and the commentary immediately splits into two camps: those declaring the start of a new inflation era, and those insisting it will all blow over by next week. Both camps are usually half right and entirely too confident. The interesting question is almost never whether oil went up. It is what the oil price is landing on, and who has to respond to it.
This time, the answer to that second question is uncomfortable. The oil price is landing on an Australian economy where inflation never fully went home, and it is landing on a Reserve Bank that has quietly changed its posture from patient to pointed. That combination matters far more than the direction of any single Brent futures contract.
What has actually happened
The immediate trigger is the Middle East, again. Brent crude pushed back above US$85 a barrel this week after the United States launched a fresh wave of strikes against Iran and reinstated a naval blockade near the Strait of Hormuz, through which a large share of the world’s seaborne oil passes. Prices have risen roughly 7 per cent over the past month and are up close to a quarter over the past year. An interim peace agreement that had calmed markets earlier in the year now looks a good deal less durable, and the market is being reminded that geopolitical risk does not resolve in a straight line.
Locally, the effect was quick. The market fell on the initial spike, with the large miners leading the way down on renewed fears about growth and inflation, while energy names rose. That much is the familiar choreography. The part worth pausing on is what came from the Reserve Bank. Its officials signalled that a higher rate of unemployment may be necessary to bring inflation down, and noted that expansionary policy had helped feed the problem in the first place. A central bank saying, in effect, that some economic pain is now part of the plan is not a throwaway line. It is a change in the reaction function.
Why the simple reading is wrong
The tempting interpretation is binary. Either Hormuz closes and oil goes to the moon, or it does not and the whole thing fades. Trading that binary is a good way to lose money in both directions, because the strait has been threatened many times and closed almost never, and because the market has learned to fade each headline until the one time it should not.
The more useful lens is transmission. An oil shock does not hurt because of the number on the screen. It hurts because of how that number seeps into transport costs, then goods prices, then expectations, then wages, and finally into what a central bank feels it must do. And that is precisely why this shock is more awkward than the last one. It is arriving into an economy where the disinflation was never finished.
Consider where Australian inflation actually sits. Since the move to monthly figures, the annual rate has hovered around 4 per cent, at 4.0 per cent in May after 4.2 per cent in April and 4.6 per cent in March, all comfortably above the 2 to 3 per cent target. The trimmed mean, the measure the Bank watches most closely, has been running near 3.6 per cent, its highest in well over a year. Services inflation and housing costs remain sticky. This is not an economy with spare disinflationary momentum to absorb a fresh energy shock. It is an economy already struggling to get the last stretch of the job done, now handed a new source of upward pressure.
The Reserve Bank has responded in kind. The cash rate sits at 4.35 per cent after the Bank raised it again earlier this year, and the language has hardened. When a central bank starts talking openly about the level of unemployment it may need to tolerate, it is telling you that its patience with above-target inflation has run out, and that it is prepared to prioritise price stability over growth if forced to choose. Markets that are still positioned for a gentle easing cycle should read that carefully.
The second-order effects worth watching
Here is where it gets genuinely interesting, and where the headlines are least helpful.
The first second-order effect is the tension inside policy itself. Earlier in the year the fuel excise was cut sharply, from 52.6 cents a litre to 20.6 cents, which softened the impact of higher pump prices for households. That is a fiscal decision that cushions the cost of living, but it also props up demand and blunts the very signal higher oil prices are meant to send. In other words, one arm of government is easing into the same inflation problem the Reserve Bank is trying to squeeze. When fiscal and monetary policy pull in opposite directions, the central bank usually wins the argument, but only by pressing harder and for longer than it otherwise would have. That is a headwind for anyone hoping rates come down soon.
The second effect is distributional across the market. An oil shock is not uniformly bad for equities. Energy producers gain. Businesses with genuine pricing power pass the cost through and protect their margins. The losers are the highly leveraged, the rate-sensitive, and the consumer-facing businesses that cannot raise prices without losing volume. A shock like this does not lower the whole market evenly; it sorts it.
The third effect is the one most people forget until it arrives: expectations. The real danger in an oil shock is not the first-round hit to petrol prices, which fades. It is the risk that persistent price pressure, layered on top of already elevated inflation, starts to shift what households and businesses expect prices to do next. Once expectations drift, a central bank has to work much harder to pull them back, which is exactly the scenario that leads to the higher unemployment its officials have now begun to mention out loud.
What long-term investors should actually do
None of this is a call to make heroic macro bets. Predicting the next move in the Strait of Hormuz is not an investment strategy; it is a coin toss with commentary attached. The practical response to a shock landing on a fragile disinflation and a hardening central bank is not to trade the headlines, but to make sure the portfolio is built to cope with a wider range of outcomes.
For long-term investors, the useful questions are these. Do the businesses you own have real pricing power, so that a period of stickier inflation is an inconvenience rather than a wound? Are their balance sheets strong enough that higher-for-longer rates do not force awkward decisions? Are you relying, perhaps without realising it, on a rate-cutting cycle that the Reserve Bank has just told you it is in no hurry to deliver? A portfolio that can answer those questions calmly does not need to guess the oil price.
The lesson is not to panic, and it is certainly not to chase energy stocks after they have already jumped. It is to think clearly about transmission rather than headlines, to respect quality and balance sheet strength when a central bank has stopped apologising, and to remember that the investors who do well through episodes like this are rarely the ones who predicted the shock. They are the ones who did not need to.
TAMIM Takeaway
Oil is back above US$85 on renewed conflict in the Middle East, and the reflex is to argue about whether it lasts. The more important point is what it lands on. Australian inflation is still running around 4 per cent, the trimmed mean is drifting higher, and the Reserve Bank, at a cash rate of 4.35 per cent, has begun to say the quiet part aloud: that it may need to tolerate higher unemployment to finish the job. Meanwhile a fuel excise cut is easing into the same problem the Bank is trying to solve.
For long-term investors, the mindset that matters is not prediction but preparation. Own businesses with pricing power and sound balance sheets. Do not assume rate cuts that the Bank has not promised. Treat each Hormuz headline as noise, and the change in the central bank’s posture as signal. The goal is not to outguess the oil market. It is to hold a portfolio that does not need you to.
