China weaponizes semiconductor supply chains against Taiwan

China is using export controls on germanium and high-purity quartz—critical inputs for Taiwan's chip and photonics industries—as economic coercion, matching Taiwan's own restrictions on advanced chip exports to the mainland. The move targets the materials that undergird Taiwan's ability to manufacture cutting-edge semiconductors and optical components. It exposes how deeply integrated but politically hostile the two economies remain, and indicates that future semiconductor competition will be fought as much through material gatekeeping as through manufacturing capability.

Tungsten hexafluoride shortage exposes chip supply fragility

Source: Chartbook

Tungsten hexafluoride—a critical precursor chemical for semiconductor manufacturing—has become a visible choke point in the chip supply chain, with prices tripling year-over-year as demand from AI and advanced processor production collides with concentrated supplier capacity. The shortage exposes how the semiconductor industry's complexity extends far beyond fabrication plants to obscure upstream chemicals where a handful of suppliers can create economy-wide constraint, making diversification of chemical manufacturing as strategically important as foundry redundancy for Western supply chains.

Hormuz Blockade Cuts Off Critical Chemicals for Chipmaking

Source: Bloomberg

The Strait of Hormuz closure is exposing concentrated chemical supply chains. Helium, bromine, and sulfur sourced primarily from the Gulf region now face weeks-long delays that constrain semiconductor fabrication. The vulnerability isn't a silicon shortage but specialty industrial gases and processing chemicals that enable chip production. Chipmakers relying on just-in-time inventory and single-region sourcing will face production halts before wafer-level impacts materialize.
