Taiwan Power Costs and Material Risks Could Impact Component Availability

Key Takeaways:

• The Iran conflict is beginning to expose structural vulnerabilities in semiconductor supply chains, particularly in Taiwan and South Korea, where production is highly dependent on imported fuel and concentrated manufacturing ecosystems.
• Immediate disruption remains limited, but pressure is building in upstream materials such as helium and petrochemical-derived inputs, which are critical to advanced chip fabrication and difficult to substitute at scale.
• Risk is not evenly distributed: advanced logic and memory segments are more exposed due to their energy intensity and geographic concentration, while commodity components remain relatively insulated under current conditions.

The escalating conflict involving Iran is no longer confined to oil markets and its increasingly seeping to a semiconductor supply-chain risk, particularly for Taiwan and South Korea, two of the world’s most critical chip manufacturing hubs whose ecosystems remain structurally dependent on imported energy and upstream materials.

Taiwan’s latest official data shows that 95.8% of its energy supply is imported, underscoring its heavy reliance on external fuel sources. South Korea faces a similar structural constraint, importing nearly all of its energy, with roughly 70% of crude oil and about 20% of LNG typically sourced from the Middle East. That dependence becomes more significant when viewed against the vulnerability of the Strait of Hormuz, which handles about 20 million barrels per day of oil and close to 20% of global LNG trade, much of it flowing to Asia.

Not Shutdowns Yet but Risk in Structural Fragility

At this stage, there is no evidence of widespread fab shutdowns. The more relevant risk is structural which are rising power costs, constrained access to specialty inputs, and increased fragility in already concentrated semiconductor supply chains.

Major manufacturers continue to operate normally, and TSMC has indicated that it does not expect significant operational disruption at this stage. But focusing only on immediate disruption misses the bigger issue. The conflict is beginning to test the resilience of a supply chain that is already highly concentrated, energy-intensive, and sensitive to upstream inputs.

Taiwanese authorities have moved quickly to stabilize near-term energy supply, confirming sufficient natural gas availability through April, securing a substantial portion of LNG needs for May, and planning increased imports from the United States beginning in June. These measures reflect how critical energy continuity has become for a semiconductor sector facing rising electricity demand from AI-related expansion.

Taiwan’s own energy planning has already flagged growing power consumption tied to semiconductor growth, meaning even temporary disruptions could carry outsized implications over time.

In South Korea, the response has followed a similar logic, but with a broader focus on industrial inputs. The government has stepped up monitoring of supply chains linked to Middle Eastern imports, particularly naphtha and other petrochemical feedstocks, while leaning on strategic reserves and adjusting the domestic energy mix to reduce reliance on imported fuel.

Additional crude supply agreements and conservation efforts suggest a system preparing for prolonged uncertainty rather than a short-lived shock. That matters because companies such as Samsung Electronics and SK hynix anchor the global memory market, where production depends not only on stable power, but also on a steady flow of specialized materials.

Materials Risk Is Emerging Alongside Energy Exposure

Beyond fuel, the conflict is beginning to affect specialty gases and semiconductor process materials, where supply chains are often even more concentrated.

One immediate pressure point is helium. Qatar, which accounts for roughly 30% of global helium supply, has experienced disruptions that temporarily halted production. Helium is a critical industrial gas used across semiconductor manufacturing.

Major producers such as Samsung Electronics and SK Hynix typically maintain several months of specialty-gas inventory, and alternative supply channels from the United States and other producers could help offset disruptions in the near term. That helps explain why there has been no immediate impact on wafer output.

However, the risk profile is asymmetric. If disruptions persist, supply may tighten unevenly, and producers may prioritize higher-margin or strategically important applications, creating selective shortages rather than broad-based constraints.

Beyond helium, the risk broadens into memory-related process materials. TrendForce reported that bromine is used in semiconductor etching, and that high-purity hydrogen bromine (HBr) is used for polysilicon etching in DRAM and NAND flash production. That does not mean memory shortages are inevitable, but it does mean a prolonged conflict could move the market from general energy anxiety into selective materials stress, particularly for Korean memory output and for semiconductor categories already tied to tight, AI-led demand.

Which Components Are Most Exposed

Based on where the current disruption is concentrated, the first pressure points are more likely to emerge in advanced semiconductors than across the full components market. The categories worth watching most closely are memory devices such as DRAM, HBM, and NAND, as well as advanced logic and AI-oriented chips produced in Taiwan’s power-intensive foundry ecosystem and South Korea’s memory-heavy manufacturing base. The issue is that they sit closest to the combination of risk now building around LNG, electricity stability, helium, and etching-related materials.

At the moment, this does not look like a generalized shortage story for the entire components universe. It looks more like a selective exposure story centered on chip supply chains that depend heavily on Taiwan and South Korea, especially where production cannot easily switch to alternate nodes, alternate fabs, or alternate materials.

The next phase will likely depend on whether Taiwan and South Korea can keep replacing disrupted energy volumes without materially higher power costs, whether Qatar’s helium outage remains prolonged enough to tighten real industrial supply, and whether materials tied to semiconductor etching and petrochemical processing become harder to source. If those pressures intensify together, the market could shift from resilience mode into selective tightness for memory, AI infrastructure, and advanced semiconductor supply chains.
