US chip stocks continued their decline on July 13 as the escalating conflict between Washington and Tehran entered a dangerous new phase. Over the weekend, US Central Command launched airstrikes on approximately 140 Iranian military installations, while Iran retaliated against regional US bases and declared the Strait of Hormuz closed. This geopolitical turmoil has triggered a broad market sell-off, but the semiconductor sector faces uniquely severe headwinds.
Intel (INTC) fell 4%, while AMD and Broadcom each dropped 2% in Monday's trading. The sell-off reflects growing investor concern that the conflict could choke the global technology supply chain, far beyond the immediate oil shock. For chipmakers, the Middle East holds an irreplaceable resource: noble gases and critical minerals essential for semiconductor fabrication.
Helium: The Invisible Bottleneck
Qatar alone supplies over one-third of the world's helium, a gas critical for heat management and precise temperature regulation during wafer processing. The Ras Laffan industrial facilities have already faced disruptions, and with the Strait of Hormuz now blocked by Iranian forces, the global supply chain for these specialized materials has ground to a halt. Without viable alternatives for helium and bromine, top-tier foundries face immediate production throttling, directly impacting revenue.
This crisis comes at a particularly bad time for the semiconductor industry, which has been pricing in an artificial intelligence (AI) boom. Tech companies are spending hundreds of billions on AI data centers, leaving chip designers and manufacturers operating on ultra-tight timelines and vulnerable supply lines. The closure of the Strait forces massive maritime detours and sends jet fuel prices soaring, inflating air and sea freight costs exponentially.
Logistical Nightmare for a Global Industry
Semiconductor manufacturing is a multi-step global relay race: raw materials, silicon ingots, and packaged chipsets cross oceans multiple times before final assembly. Escalating regional warfare piles huge logistical costs onto a capital-intensive industry, squeezing corporate margins and forcing analysts to drastically cut earnings estimates for the world's most valuable chip stocks. The Dow opened higher but chip stocks continued to slide, highlighting the sector's vulnerability.
The swift back-and-forth between Washington and Tehran has shattered any illusions of a brief, contained skirmish. Instead, Wall Street is realizing that this conflict may mirror the grinding, multi-year reality of the Russia-Ukraine war—one that defies quick diplomatic or military resolution. If this war drags into a prolonged war of attrition, the supply chain bottlenecks threatening the semiconductor sector could harden into a permanent economic drag.
Bearish Outlook for Second Half of 2026
For a chip industry heavily exposed to cyclical downturns and priced for perfection on the back of the AI boom, an extended Middle Eastern conflict could derail earnings. With no off-ramp in sight, chip stocks are bracing for a highly turbulent and deeply bearish second half of 2026. The Asian markets tumbled as oil surged on Strait tensions, further pressuring chip stocks and bonds.
Investors should monitor developments in the Strait of Hormuz and any diplomatic efforts to de-escalate the conflict. The proposed 20% cargo fee on the Strait could add further costs to an already strained supply chain. Meanwhile, the DRAM ETF plunged 8% as SK Hynix, Samsung, and Micron stocks tumbled on profit-taking, reflecting broader sector weakness.
