ASX Energy Stocks stay in focus as oil holds high after Trump extends the Iran ceasefire
U.S. President Donald Trump extended the Iran ceasefire overnight, saying the truce will hold until Tehran puts a fresh proposal on the table. But the U.S. naval blockade on Iranian ports stays in place. Brent crude briefly pushed above US$100 a barrel on Tuesday before easing back to around US$98, while WTI is trading near US$89 after a roughly 8% jump over two sessions. The Strait of Hormuz is still broadly shut, with only a handful of ships passing through. For ASX energy investors, the message is simple: this is a pause, not peace. The crisis is being stretched out, not solved, and that keeps ASX oil and gas names firmly in the sweet spot. The real question is how long this window lasts.
Why the Ceasefire Extension Keeps Oil Prices High
A ceasefire on paper is not the same as oil flowing freely. The Strait of Hormuz normally carries about 20% of the world’s oil and LNG. With traffic still mostly blocked, analysts estimate up to 5 million barrels a day of global supply is already being lost, roughly 5% of world output. In our view, the market is pricing in a “stalemate premium”, not peace and not full-blown war.
Economists have already warned that even if the ceasefire holds, the supply shock will keep dragging on global growth. The next things to watch are fresh U.S.-Iran talks (currently on hold after Vice President JD Vance’s Pakistan trip was delayed) and joint diplomacy from Western allies. Until one of those produces a real breakthrough, oil has little reason to sell off hard.
ASX Energy Stocks Winners: From Ampol to Small-Cap Oilers
Not all ASX energy stocks win equally from this backdrop. Refiners capture fatter margins, while producers capture higher prices.
Ampol (ASX:ALD) is the standout refiner story. Its Lytton refinery in Brisbane saw its refiner margin jump to US$25.45 a barrel in the first quarter of FY26, up from just US$6.07 a barrel a year earlier, with fuel sales up 4.7%. That is a roughly four-fold margin jump, and the shares have responded.
Woodside (ASX:WDS), Australia’s largest oil and gas producer, offers the cleanest LNG exposure. With Hormuz handling such a large share of global LNG, any prolonged disruption tightens the market Woodside sells into. Santos (ASX:STO) is an integrated oil and gas play with rising output from its Barossa and Pikka projects, giving it more barrels to sell into a higher price deck.
For sharper leverage, Karoon Energy (ASX:KAR) is a smaller-cap producer with Brazilian operations whose earnings move almost directly with Brent. Beach Energy (ASX:BPT) offers domestic gas exposure with a recent focus on cost discipline, making it the more defensive pick in the group.
The Investor’s Takeaway: When Does This Trade End?
We believe the current setup favours ASX energy stocks in the near term, but the trade is getting crowded. The key risk is simple: if a proper U.S.-Iran deal lands and Hormuz reopens, the unwind could be brutal. On the April 7 ceasefire, Brent fell roughly 13%, and WTI dropped more than 16% in a single session. That shows just how fast these gains can evaporate.
In our view, short-term traders comfortable with geopolitical swings can still play this rally, but long-term investors are better off waiting until the next round of peace talks concludes before adding fresh exposure. The next major catalysts to watch are the resumption of U.S.-Iran negotiations and any coordinated Western move to reopen Hormuz. Either one could flip this trade in a single session.
