Standard Chartered’s economist Madhur Jha has flagged a significant near-term risk to global equity markets: an effective closure of the Strait of Hormuz and the resulting energy shock could undermine the AI investment thesis that has driven much of the recent rally in tech-heavy indices.
The Strait of Hormuz is the world’s most critical oil chokepoint, with roughly 20% of global petroleum supply passing through it daily. Any sustained disruption would sharply lift energy costs โ a direct input cost for data centres and semiconductor fabrication plants that underpin the AI boom.
Two-Stage Risk to AI Optimism
Standard Chartered identifies the threat in two layers. First, the near-term risk centres on semiconductor input supplies โ manufacturing chips requires stable, affordable energy, and an energy shock would squeeze margins and potentially delay production timelines for the world’s leading chipmakers.
The longer-term risk is a pull-back in AI investment and demand more broadly. If energy costs remain elevated, the economics of building and running large AI data centres deteriorate โ potentially causing hyperscalers to reconsider capital expenditure plans.
What This Means for Australian Traders
For ASX investors, the concern is indirect but real. Australian technology stocks and companies with exposure to global semiconductor supply chains โ including some holdings within ASX-listed tech ETFs โ could face headwinds if the AI spending cycle stalls.
Equally, a sustained energy shock would likely push oil prices higher, lending short-term support to ASX-listed energy stocks such as Woodside Energy (WDS) and Santos (STO). However, the broader equity sell-off risk from an AI growth scare could outweigh those gains for diversified portfolios.
The AUD/USD cross is also worth monitoring. A global risk-off move driven by energy disruption would typically weigh on the Australian dollar, given its sensitivity to commodity sentiment and global growth expectations.
What to Watch Next
Traders should monitor any escalation in Middle East tensions affecting Hormuz transit, alongside upcoming capital expenditure guidance from major US tech firms. Any downward revision to AI infrastructure spending would be a clear negative signal for ASX tech-exposed positions.
Bias: Wait-and-see. The risk is flagged but not yet materialised โ watch energy prices and Hormuz shipping data closely before repositioning.
