Beyond Oil — Six Semiconductor Supply Lines Cut by the Strait of Hormuz

Everyone is watching oil. They should be. But crude isn't the only thing flowing through the Strait of Hormuz.

Six supply lines that feed the entire semiconductor industry pass through the same chokepoint. Helium, LNG, sulfur, aluminum, noble gases for lithography, and petrochemicals for chip packaging. All six are disrupted. Strait traffic is down 95–98%.

The First Hit — LNG and the Power Crisis in Taiwan and South Korea

Taiwan manufactures 90% of the world's most advanced semiconductors. TSMC leads that production. Taiwan also generates 48% of its electricity from LNG, with Qatar supplying over 34% of that gas.

Nothing is moving out of Qatar right now.

To make matters worse, Taiwan decommissioned its last nuclear reactor in 2025. Semiconductor fabs require 24/7 power, and that power foundation is cracking.

South Korea faces the same vulnerability. Over 25% of its natural gas comes from the same source. Its memory chip producers account for more than 60% of global memory output. The energy risk cascading from Hormuz directly threatens the backbone of global memory supply.

The Second Hit — Helium, the Irreplaceable Input

Qatar produces 33% of the world's helium. This is the fourth helium shock since 2021.

Helium is essential for manufacturing memory chips. There is no substitute. South Korea sources 64% of its helium directly from Qatar, and semiconductor fabs typically carry only two to four weeks of buffer stock.

When that runs out, production doesn't slow down. It stops entirely.

The Third Hit — Sulfur and the Domino Into Copper

Most people don't connect sulfur to semiconductors. But the Gulf produces 44% of the world's sulfur. Ultra-pure sulfuric acid is used to clean silicon wafers across every chip type.

Sulfur is also critical for copper extraction. Copper is in every chip, every circuit board, every data center cable. A sulfur shortage compounds into a copper shortage, which raises costs across the entire data center buildout.

The Remaining Three — Aluminum, Noble Gases, Petrochemicals

That covers three of the six disrupted lanes. The other three also flow through Hormuz:

  • Aluminum: used in semiconductor packaging and heat dissipation
  • Noble gases: essential for EUV and DUV lithography lasers
  • Petrochemicals: raw materials for chip packaging

All six lanes are seeing 10–18% cost inflation since the conflict began.

Historical Parallels — 1973, 2021, and Now

The 1973 oil embargo disrupted a single resource. Prices went from $2 to $11 per barrel — a 450% increase. Inflation surged from 3% to over 12%.

In 2021, the Ever Given blocked the Suez Canal for six days. Just six days. Semiconductor supply chains were disrupted for months, costing the global economy an estimated $240 billion.

Those were each a single resource and a temporary incident. What's happening now involves six supply lines feeding the technology stack, and it's an active, ongoing conflict. The scale is categorically different.

DRAM and SSD prices are already up 130% year-over-year per Gartner. Demand was maxed out before a single ship got blocked. The longer this crisis persists, the more likely it is that the entire semiconductor industry's cost structure shifts permanently.

FAQ

Q: How long can semiconductor fabs operate without new helium supplies? A: Most fabs carry two to four weeks of helium buffer stock. South Korea sources 64% of its helium from Qatar, so fabs there are the most immediately exposed. Once inventory depletes, production halts completely — there's no workaround or substitute.

Q: Could alternative shipping routes bypass the Strait of Hormuz? A: There is no viable alternative for LNG and helium shipments from Qatar. Unlike oil, which has pipeline alternatives in some cases, Qatar's gas exports are almost entirely seaborne through the Strait. Rerouting around Africa would add weeks and is not feasible for maintaining just-in-time supply to fabs.

Q: How does this compare to the 2020–2021 chip shortage? A: The 2020–2021 shortage was primarily demand-driven — pandemic-era electronics demand surged while supply adjusted. This crisis is supply-driven across six simultaneous channels, with an active military conflict as the cause. The disruption is broader, more severe, and harder to resolve with production adjustments alone.
