ASX sectors could swing sharply as the US-Iran ceasefire nears its deadline
The US-Iran ceasefire expires on Wednesday, April 22, and the past 48 hours have already shown how quickly markets can swing. Iran closed the Strait of Hormuz again on Saturday, Iranian gunboats fired on tankers, and US Navy forces seized an Iranian-flagged ship in the Gulf of Oman. Brent crude jumped over 7 per cent to around US$96 per barrel, pushing back towards the psychologically important US$100 level and erasing most of last week’s decline.
For ASX investors, Wednesday creates a binary event with real consequences. In our view, markets are hoping for an extension but are not positioned for a collapse, and that asymmetry is where the opportunity lies. Investors should also watch for a third scenario: a short-term ceasefire extension of around two weeks, which would keep volatility elevated but prevent an immediate price blow-out.
What are the Best ASX Stocks to invest in right now?
Energy Stocks Face the Sharpest Swings
Santos (ASX:STO), Woodside (ASX:WDS), Viva Energy (ASX:VEA) and Ampol (ASX:ALD) are the most directly exposed ASX names. Upstream producers benefit from sustained higher oil prices, while refiners capture wider margins when fuel supply tightens.
If Wednesday delivers a ceasefire extension, expect a sharp pullback as the risk premium unwinds. If talks collapse, Friday’s 10 per cent oil swing becomes the floor, not the ceiling. We believe Ampol faces the most complex margin dynamics. It captures higher retail fuel prices and benefits from Lytton running flat-out, but its greater reliance on imported refined products during Geelong’s shutdown leaves it exposed to shipping insurance spikes if Strait tensions escalate.
Gold Miners Could Test Fresh Highs
Gold tested US$4,887 per ounce on Friday, roughly A$7,000 at current exchange rates, and remains elevated above the critical US$4,800 support level despite minor Monday morning profit-taking. Northern Star Resources (ASX:NST), Newmont (ASX:NEM) and Evolution Mining (ASX:EVN) should open strongly.
What makes this cycle different is that gold held above US$4,800 through both Friday’s optimism and the weekend’s escalation. This suggests structural buying, not just reactive flows. We believe ASX gold miners, which have lagged the metal itself for much of this cycle, could finally play catch-up if Wednesday delivers a negative outcome.
Defence Stocks Gain if the Ceasefire Collapses
DroneShield (ASX:DRO) and Electro Optic Systems (ASX:EOS) rallied 12 per cent and 15 per cent, respectively, when the Iran drone threat first hit markets in March. A ceasefire collapse reactivates that trade.
The key point for investors is that counter-drone demand is not a short-term story. Even if Wednesday produces a deal, systems ordered during this conflict take years to fulfil. These stocks benefit from both extended conflict and longer-term rearmament.
Banks Face Indirect Pressure
The Big Four banks and Macquarie (ASX:MQG) have no direct exposure to the Strait, but they have indirect exposure to the rate path. Higher oil prices keep inflation sticky, which keeps the RBA cautious and delays rate cuts. This suggests volatility rather than a clear direction this week. Higher-for-longer rates support bank margins, but weaker consumer spending eventually hurts loan growth.
Consumer Stocks Could Feel the Squeeze
Discretionary retailers like Wesfarmers (ASX:WES) and Super Retail Group (ASX:SUL) are most vulnerable if oil stays elevated. Every dollar spent at the fuel pump is a dollar not spent at Bunnings or Kmart. The concern is compounding: if Wednesday triggers another oil spike, consumer confidence could weaken materially into the May retail reporting period.
The Investor’s Takeaway
Our view is simple. Do not try to predict Wednesday’s outcome. Position for volatility instead.
For growth investors, energy winners look stretched after Monday’s run, and rotating into defence names offers cleaner conflict exposure. For income investors, gold miners such as Northern Star provide portfolio balance. For conservative investors, holding elevated cash this week is a legitimate position. Whatever Wednesday delivers, it will define how the second quarter unfolds for multiple ASX sectors.
