Rising Geopolitical Tensions Affecting Supply Chains in the Auto Industry

The ongoing conflict in Iran introduces substantial risks to the global auto industry, which is already grappling with supply constraints during a critical transition phase. While Iran is not a leading producer of automotive parts, its geopolitical position casts a long shadow over resources essential for automotive manufacturing, particularly oil and aluminum. The Strait of Hormuz, bordering Iran and Oman, is a crucial shipping corridor through which approximately 20% of global oil flows, according to the U.S. Energy Information Administration. Recent escalations have driven oil prices beyond $100 a barrel, triggering immediate consequences throughout the economy, including higher gas prices that have reached over $3 per gallon in places like Iowa.

The repercussions extend beyond just fuel prices. With the increase in oil prices, the cost of petrochemicals—vital for the production of plastics that make up roughly 30% of automotive components—is set to rise. Dan Hearsch, managing director at AlixPartners, points out that the region's refining capabilities are central to the production of key petrochemical feedstocks like ethylene and propylene. Additionally, Bahrain and the UAE together account for 9% of global aluminum smelting, and the U.S. is heavily reliant on aluminum imports, with 80-90% sourced from abroad, including 20% from this volatile region. As geopolitical tensions escalate, concerns grow that disruptions to these vital raw materials could hamper car manufacturing at a time when the industry is attempting to pivot towards electric and more sustainable vehicles.

Although experts like Duncan Wood from the Wilson Center indicate that the current price surge may not reach extreme peaks, such as $200 per barrel, the reality remains that sustained high oil prices will likely lead to increased operational costs across the supply chain. Even if tensions ease in the short term, logistical challenges—including shipping bottlenecks and insurance premiums—could prolong elevated prices for essential materials. Such dynamics may pose a threat not only to supply capabilities but also to the overall financial performance of companies within the petrochemical and automotive sectors.

In related developments, analysts suggest the conflict may benefit certain companies, notably chemical manufacturers like Dow Inc. The recent upgrades of Dow’s stock reflect an expectation of rising commodity prices that could enhance margins for the company. The analyst’s projections indicate that the ongoing geopolitical tensions could have a cascading effect, causing long-lasting disruptions to supply chains that manufacturers are forced to navigate carefully. Meanwhile, Westlake Chemical Partners LP, also part of the petrochemical sector, needs to remain vigilant in adapting its strategies to mitigate vulnerabilities posed by geopolitical conflicts, thereby safeguarding its operational integrity and long-term value in the market.
