Oil slides on Iran deal hopes as the ASX posts its best week in two months

This ASX market update for June 2026 covers a week defined by one story: the prospect of peace with Iran. The ASX 200 closed Friday at 8,804, up about 2.1% for the week and its strongest five days in two months, as Brent crude fell roughly 6% to near US$85 a barrel. Falling oil and softer local data lifted sentiment heading into a pivotal Reserve Bank decision.

Global Markets

Iran set the tone. On 11 June, President Trump called off planned strikes and signalled a deal that would lift oil sanctions and reopen the Strait of Hormuz could be signed within days. Markets moved quickly to price the outcome: crude fell, equities firmed, and bond yields softened.

US stocks recovered a weak, technology-led start to the week. A near 2% rally on Thursday and SpaceX’s 19% market debut on Friday restored confidence, leaving the S&P 500 at 7,431, up 0.6% for the week. Breadth, rather than the megacap growth names that have led all year, did the work: nine of eleven sectors finished higher while large growth fell around 1%.

S&P 500+0.6%

Europe was firmer, with the Euro Stoxx 50 up 1.3%. Asia was more volatile: the Hang Seng broke a seven-session losing streak with a 1.93% jump on Friday but still finished the week lower.

The ASX

The ASX 200 closed at 8,804, up about 2.1% for the week. Two tailwinds drove the move: falling oil and a dovish repricing of the domestic rate outlook after softer economic data. Consumer cyclicals led, rallying more than 8% across the five sessions, with staples close behind at 7.5%.

Insurance broker Steadfast led the market, with a2 Milk and Lendlease also strongly higher. Uranium names Silex and Nexgen, along with gold miner Ora Banda, were the heaviest fallers. The rally came directly ahead of the RBA meeting, with the cash rate at 4.35% following three increases this year.

A Message From Our Founder

Markets spent the week pricing two things that have not yet happened: peace with Iran, and a pause from the RBA. Both are plausible. Neither is confirmed.

The oil move is the one to watch. A reopened Strait of Hormuz and lifted sanctions would be genuinely disinflationary, and the market is already leaning into that outcome through lower crude, firmer equities and a softer rate path at home. But an 80% probability quoted by an official still leaves a one-in-five chance of disappointment, and crude remains more than 20% above where it sat before the conflict began. The risk is not that the optimism is misplaced. It is that the good news is already in the price.

Domestically, the Reserve Bank’s decision is the near-term pivot. A pause at 4.35% looks likely, yet underlying inflation is still expected to sit above 3% well into next year. A pause is not a pivot, and investors would do well to keep that distinction in mind. Our investment approach is built for exactly this kind of environment, where the rally is real but rests on outcomes that are still being negotiated.
