On March 10, 2026, the escalation of military hostilities between the United States, Israel, and Iran has introduced significant operational risks to the global semiconductor industry. The conflict is impacting manufacturing facilities in the region and disrupting the maritime transit of critical raw materials. Industry analysts and corporate reports indicate that the primary pressures stem from heightened energy costs and potential shortages of noble gases essential for lithography processes.
In Israel, a major global hub for semiconductor design and production, operations are facing logistical constraints. Intel Corporation, which operates the Fab 28 facility in Kiryat Gat and is currently constructing the $25 billion Fab 38 site, has implemented enhanced security protocols. While the company has not officially announced a suspension of production, local reports suggest that workforce availability and supply deliveries have been hampered by regional instability. Tower Semiconductor, based in Migdal HaEmek, is similarly navigating logistical challenges as commercial flight cancellations and shipping diversions affect the movement of specialized equipment and personnel.
The conflict has also triggered a surge in energy prices, which directly impacts the high-precision, energy-intensive environment of semiconductor fabrication plants (fabs). Global energy markets have responded to threats surrounding the Strait of Hormuz, a critical chokepoint for approximately 20% of the world’s liquefied natural gas and oil supply. For leading manufacturers such as TSMC and Samsung, which operate large-scale fabs in East Asia, the rising cost of electricity and fuel is inflating operational expenditures. Preliminary estimates from industry groups suggest that a sustained 10% increase in energy costs can reduce gross margins for Tier 1 foundries by approximately 150 to 200 basis points.
Supply chain vulnerabilities are further exacerbated by the potential disruption of noble gas supplies, including neon, krypton, and xenon. These gases are critical for the operation of Deep Ultraviolet (DUV) and Extreme Ultraviolet (EUV) lithography machines. While many manufacturers have diversified their sourcing since 2022, the current regional instability threatens the transit routes used to move these materials from Eurasian suppliers to manufacturing hubs in Asia and North America.
As of the market close on March 10, the Nasdaq Composite stood at 22,697.1, a marginal gain of 0.01% for the day, while the S&P 500 fell 0.21% to 6,781.5. The Dow Jones Industrial Average declined 0.07% to 47,706.5. Market volatility remains elevated, with the VIX recorded at 25.5, despite a 13.5% decrease during the session. The 10-year Treasury yield was 4.15%, with the 2-year yield at 3.56%, maintaining a spread of 0.56%. The Semiconductor Industry Association (SIA) issued a statement on Tuesday noting that it is closely monitoring the situation and coordinating with government agencies to ensure the continuity of the microelectronics supply chain.
