While global markets have spent weeks tracking the volatility of helium supplies following disruptions in Qatar, a far more precarious vulnerability is simmering in the southern deserts of Israel. The ongoing instability between Israel and Iran has exposed a structural failure in the global semiconductor memory supply chain—one that threatens to halt the production of the chips powering everything from the smartphone in a user’s pocket to the massive data centers driving the artificial intelligence revolution.
The risk centers on bromine, a raw material essential for producing semiconductor-grade hydrogen bromide gas. This specialized chemical is the primary etching agent used by South Korean fabrication plants to carve the intricate transistor structures of Dynamic Random-Access Memory (DRAM) and NAND flash chips. Without it, the world’s most advanced memory production would effectively grind to a halt.
South Korea, the global hub for memory chip production, sources 97.5 percent of its bromine imports from Israel. This extreme concentration of supply creates a single point of failure that is now sitting directly within the range of Iranian ballistic missiles.
The Dead Sea Chokepoint
The heart of this vulnerability is the Dead Sea, one of the most bromine-rich environments on earth. The ICL Group, an Israeli multinational, dominates the extraction and conversion process at its Sodom facility. Because extraction and the conversion into semiconductor-grade gas happen at the same site, the entire process is concentrated in a narrow geographic corridor.
Recent military activity has brought the threat into sharp focus. Iranian missile strikes have targeted the Negev—Israel’s southern desert—hitting areas such as Dimona and Arad. Both locations are within 35 kilometers of ICL’s production complex. While the facility remains operational, the proximity of these strikes demonstrates that critical industrial infrastructure can be compromised without a direct hit; for example, the Haifa oil refinery was previously forced offline after a power station was damaged in an attack.
Beyond the physical risk of missile strikes, the logistics of shipping are becoming increasingly precarious. War risk insurance for vessels calling at Israeli ports has climbed from 0.2 percent to as high as 1.0 percent of vessel value per seven-day call. For a mid-sized cargo ship, this adds up to $500,000 in additional costs per voyage. Shipping lines, including Israel’s ZIM, have already implemented war risk premium surcharges, signaling that the cost of maintaining this supply chain is rising even during ceasefires.
A Chemical Requirement With No Substitute
The reason the industry cannot simply pivot to another supplier is rooted in chemistry. Hydrogen bromide gas is used during the polysilicon etching stage of DRAM and NAND production. In these processes, the gas must achieve a high “selectivity ratio”—the ability to etch polysilicon without destroying the underlying silicon oxide layer.
| Etching Agent | Polysilicon-to-Oxide Selectivity Ratio | Impact on Advanced Nodes |
|---|---|---|
| Hydrogen Bromide (HBr) | 100 to 1 | Enables functional, high-precision transistors |
| Chlorine-based Alternatives | 30 to 1 | Risk of destroying transistors at advanced geometries |
Because of this 100-to-1 selectivity ratio, bromine cannot be replaced by chlorine or other chemicals without destroying the chips. Bromine used for industrial purposes, such as flame retardants, cannot be “reconverted” into the ultra-pure, semiconductor-grade gas required by fabs. The purification process requires specialized gas-phase distillation columns capable of reducing trace metal contamination to parts-per-billion levels—infrastructure that does not exist at scale outside of a few existing providers.
While companies like Air Liquide and Resonac produce this gas outside Israel, their capacity is already fully committed to giants like TSMC and Samsung. With the AI buildout accelerating demand for high-bandwidth memory (HBM), there is virtually no spare capacity in the global market to absorb a sudden loss of Israeli production.
From AI Accelerators to Budget Smartphones
A disruption in the global semiconductor memory supply chain disruption would not be felt equally, but it would be universal. Samsung and SK hynix together control roughly 70 percent of the global DRAM market. If their access to hydrogen bromide is severed, they would likely prioritize their most profitable lines: the high-bandwidth memory (HBM) required for Nvidia’s Blackwell and Rubin GPUs.
This prioritization would abandon “commodity” DRAM and NAND—the types used in laptops, tablets, and smartphones—in severe shortage. The impact would be most acute in the Global South. In countries like Bangladesh, Nigeria, and South Africa, memory chips already account for up to 20 percent of the cost of a mid-range smartphone. In 2026, some budget devices have already begun reverting to 4 gigabytes of RAM as costs rise, potentially pricing millions of people out of the digital economy.
The risk extends into national security. The U.S. Department of Defense relies heavily on commercial off-the-shelf (COTS) procurement for the memory chips used in radar modules, electronic warfare packages, and precision-guided munitions. Because there is no separate “defense-grade” memory supply chain, a commercial shortage would directly impact the production of military guidance systems at the exact moment the same conflict is depleting existing munitions stockpiles.
Closing the Strategic Gap
Addressing this vulnerability requires a coordinated effort between South Korea, the United States, and Israel. Industry analysts suggest three primary levers for stabilization:
- Immediate Pre-positioning: Establishing bromine forward contracts to lock in supply and utilizing Arkansas-based bromine from producers like Albemarle as feedstock, provided the conversion infrastructure is built.
- Infrastructure Diversification: Expanding the “Chip 4” framework to fund the construction of semiconductor-grade hydrogen bromide conversion facilities in the U.S., Japan, and South Korea.
- Policy Designation: Adding bromine and its semiconductor-grade derivatives to the U.S. Critical minerals list and utilizing Defense Production Act authority to incentivize domestic purification capacity.
The current global reliance on a single conversion chokepoint in a conflict zone is a structural failure that transcends politics. If the Sodom facility were to go offline, the gap could not be filled in weeks or months, but only through years of permitting and construction.
The next critical checkpoint for this supply chain will be the 2030 expiration of the Dead Sea concession, which may provide an opening for allied capital to enter the extraction process in exchange for long-term supply guarantees.
