The 2026 Strait of Hormuz Crisis: Impacts on the Global Semiconductor Supply Chain

6 min read 5 views

The ongoing 2026 conflict involving the United States, Israel, and Iran has led to the effective closure of the Strait of Hormuz, a critical maritime chokepoint. While the immediate global focus has been on the disruption of oil and liquefied natural gas supplies, the crisis has exposed severe vulnerabilities in the global semiconductor manufacturing supply chain. The Middle East is a vital source of several critical materials required for chip fabrication, most notably helium, bromine, aluminum, and sulfur. The disruption of these materials, combined with skyrocketing energy costs, poses a significant threat to the global digital economy and the rapid expansion of AI infrastructure.

Geopolitical Context: The 2026 Strait of Hormuz Crisis

The current crisis began on February 28, 2026, following joint military strikes by the United States and Israel on Iran, which resulted in the death of Iran’s supreme leader, Ali Khamenei. In retaliation, Iran launched attacks on U.S. military bases, Israeli territory, and neighboring Gulf states. Crucially, Iran’s Islamic Revolutionary Guard Corps (IRGC) issued warnings prohibiting vessel passage through the Strait of Hormuz, and Iranian forces subsequently attacked commercial shipping and deployed sea mines in the waterway.

By early March, commercial traffic through the Strait had dropped to near zero. The Strait of Hormuz is a vital artery for global trade; approximately 20% of the world’s daily oil supply and significant volumes of LNG pass through it. The closure has caused Brent crude oil prices to surge past $100 per barrel for the first time in four years, peaking at $126 per barrel, and has triggered a massive spike in global natural gas prices.

The Helium Bottleneck

The most immediate and severe threat to the semiconductor industry stems from the disruption of the global helium supply. Helium is an essential, non-substitutable component in semiconductor manufacturing. It is used as a carrier gas, a purge gas to maintain sterile environments, and a critical coolant for silicon wafers during fabrication.

Qatar is the world’s second-largest producer of helium (behind the United States), accounting for approximately one-third of the global supply (roughly 63 million cubic meters in 2025). Qatari helium is extracted as a byproduct of LNG processing. During the conflict, Iranian drone strikes targeted Qatar Energy’s Ras Laffan Industrial City, forcing the facility offline and halting both LNG and helium production. Furthermore, even if production resumes, the blockade of the Strait of Hormuz prevents the export of this critical gas via traditional maritime routes.

The impact on Asian semiconductor giants is profound. South Korea, home to major memory chip manufacturers Samsung and SK Hynix, imported nearly 65% of its helium from Qatar in 2025. Taiwan, home to TSMC (which produces over 90% of the world’s advanced chips), is similarly exposed. While major chipmakers maintain strategic reserves of critical gases, typically ranging from a few weeks to several months, industry experts warn that a prolonged outage of Qatari supply cannot be easily mitigated. Phil Kornbluth, a helium industry consultant, noted that if the outage extends beyond two weeks, distributors will be forced to rework logistics and relocate cryogenic equipment, a process that could take months to resolve.

Disruption of Other Critical Semiconductor Materials

Beyond helium, the Middle East is a crucial supplier of several other materials integral to the semiconductor supply chain. The conflict and the Strait of Hormuz blockade are constraining the flow of these resources:

MaterialRole in Semiconductor ManufacturingMiddle East Supply Chain Exposure
BromineUsed in circuit formation and etching processes.Israel and Jordan produce approximately two-thirds of the world’s bromine supply. The broader regional conflict threatens these exports.
AluminumUsed in heat sinks, electrolytic capacitors, and chip packaging.The Middle East accounts for over 8% of global aluminum production. Qatar and Bahrain have suspended deliveries, forcing manufacturers to seek alternative sources.
Sulfur / Sulfuric AcidHigh-purity sulfuric acid is an essential cleaning agent used during wafer fabrication to eliminate contaminants.Countries like Saudi Arabia, the UAE, and Qatar collectively produce between 25% and 33% of the world’s sulfur.
CopperEssential for wiring and interconnects within chips and printed circuit boards.The blockade disrupts the transport of refined copper and copper ore through the Strait, exacerbating existing shortages driven by AI data center buildouts.

The Energy Shock and AI Infrastructure

Semiconductor fabrication is an incredibly energy-intensive process. The disruption of oil and LNG supplies through the Strait of Hormuz has caused a massive spike in global energy prices, which directly impacts the bottom line of chip manufacturers.

This energy vulnerability is particularly acute in East Asia. South Korea imports roughly 70% of its crude oil from the Middle East, virtually all of which travels through the Strait of Hormuz. Taiwan imports 95% of its energy, heavily relying on LNG to power its industrial sector, including TSMC’s massive fabrication plants. Sustained high energy prices will significantly increase the cost of semiconductor production.

This dynamic poses a direct threat to the ongoing boom in artificial intelligence. The production of High-Bandwidth Memory (HBM) and advanced logic chips required for AI data centers is highly resource-intensive. Analysts warn that rising material and energy costs will increase the Total Cost of Ownership (TCO) for hyperscalers (such as Amazon, Google, and Microsoft), potentially slowing the adoption and buildout of AI infrastructure. Furthermore, the conflict has seen direct kinetic attacks on tech infrastructure, with Iranian drone strikes hitting AWS data centers in the UAE and Bahrain, marking a severe escalation in the targeting of digital assets.

Industry Response and Mitigation Strategies

In response to the crisis, semiconductor manufacturers are scrambling to secure their supply chains. Companies like SK Hynix and Samsung have stated they possess sufficient inventory of helium and other materials to weather short-term disruptions, having diversified some supply lines following the 2022 Russia-Ukraine war. Samsung has also reportedly begun recycling some of the helium used in its processes.

However, if the Strait of Hormuz remains closed for an extended period (three to six months), these reserves will be depleted. The semiconductor industry is exploring alternative shipping routes, such as moving containers overland to ports in Oman (Salalah) or Saudi Arabia (Jeddah) to bypass the Strait, though this adds significant logistical complexity and cost. Ultimately, the crisis highlights the fragile nature of the highly globalized semiconductor supply chain and the urgent need for geographic diversification of critical raw materials.
