Iran Conflict Sparks Fears of Renewed Semiconductor Shortages for Australian Automakers
The ongoing conflict in the Middle East is casting a long shadow over the global automotive industry, with analysts warning of a potential return to the severe semiconductor shortages experienced during the COVID-19 pandemic. The crucial materials needed to manufacture these vital electronic components are facing significant disruptions, primarily due to shipping blockades in the Strait of Hormuz.
Reports indicate that if the current conflict in Iran extends beyond a two-month period, both semiconductors and electric vehicle (EV) batteries could face critical supply shortages. This assessment stems from data compiled by the Supply Chain Intelligence Institute Austria, which highlights that the impact of military actions in the region extends beyond fossil fuels to include essential noble gases used in the production of electronics.
Peter Klimek, an author of the study, pointed out the specific vulnerability of the semiconductor supply chain. “Around one-third of the helium needed for chip production comes from Qatar,” Klimek stated. “It will depend on how quickly chipmakers can secure alternative sources.”
While the United States remains the world’s largest producer of helium, the removal of Qatar’s output from the global supply chain could trigger substantial shortages. This comes at a time when demand for memory chips is already on the rise, fuelled by the burgeoning need for high-powered computing capable of supporting artificial intelligence (AI). This escalating demand places automakers in direct competition with other sectors for these essential components.
The Strait of Hormuz has been a focal point of disruption since early March 2026, impacting approximately 20 per cent of the world’s oil and natural gas supply, in addition to other vital non-fuel natural resources. For key nations like Qatar and Kuwait, this maritime passage is their sole access to international shipping routes.
Automakers Poised to Be Hit Hardest
Klimek issued a stark warning regarding the potential fallout for the automotive sector. “In the event of a chip shortage, the auto industry would likely be hit harder, as priority would be given to sectors such as medical applications,” he explained. This suggests that in a scenario of scarcity, the automotive industry would be at the bottom of the priority list for semiconductor allocation.
The global semiconductor manufacturing landscape is heavily concentrated, with Taiwan producing around 60 per cent of the world’s computer chips. This geographical concentration further amplifies the risk associated with any disruption to global supply lines.
Currently, Australian automakers are closely monitoring the evolving situation. However, they have yet to publicly disclose any specific contingency plans or mitigation strategies they might employ to address a potential shortage.
Lessons from Past Shortages
The automotive industry is all too familiar with the devastating impact of semiconductor scarcity. The last major shortage, triggered by supply chain interruptions stemming from the COVID-19 pandemic, forced many manufacturers to significantly curtail production capacity between 2020 and 2022. This led to widespread production slowdowns, resulting in considerable delays and extensive waiting lists for popular vehicle models.
A swift resolution to the conflict in Iran could alleviate the immediate pressure on electronics production by allowing shipping to resume without significant long-term consequences. However, as more industries grapple with the escalating costs of fuel and increasingly restricted global shipping, the critical semiconductor industry finds itself increasingly vulnerable.
