Geopolitical Risk |

Risk Propagation across Product Dependencies for GCT Semiconductor Holding, Inc. (High-purity Electronic Chemicals)

Attention: A moderate supply risk alert has been issued for GCT Semiconductor due to policy-driven delivery uncertainties in upstream petrochemical feedstocks. Initial disruptions are expected within 14 days, with the full impact materializing over 98 days, affecting the production of 4G/5G baseband chips. The risk propagation path identified by SCRT is as follows: Event → Oil Products → Naphtha/Ethylene → Semiconductor-grade Chemicals → Advanced Packaging Substrates → 4G/5G Baseband Chips → GCT Semiconductor Holding, Inc. This path is recognized by the SCRT (SupplyGraph.ai Supply Chain Risk Tracking framework), which utilizes four continuously updated 24/7 proprietary databases and advanced algorithms. These databases include a 400M+ global company database, a 1.5M+ industrial product database, a product dependency graph database, and a 5M+ global historical event database. SCRT's data-driven, objective, and traceable approach ensures accurate risk identification and impact assessment. The geopolitical risks, particularly the U.S. sanctions waivers on Russian and Iranian crude, have caused significant price volatility. Crude oil prices dropped from $102.01 per barrel on April 8 to $82.14 by June 22, while naphtha prices fell from $914.91 per metric ton to $706.54. These fluctuations have directly impacted downstream intermediates crucial for semiconductor manufacturing. The price collapse initially reduced input costs, but delivery uncertainties have propagated through GCT's supply chain. The naphtha-derived semiconductor-grade chemicals into advanced packaging substrates for 4G/5G baseband chips and photoresists and specialty gases into wafer fabrication for RF transceivers have absorbed these shocks with defined lags. The cumulative effect stretches the full transmission cycle to approximately 14 weeks, imposing a moderate supply risk on GCT Semiconductor. This turbulence is primarily driven by policy-induced delivery constraints rather than cost shifts.

### Moderate Supply Risk Impact on GCT Semiconductor GCT Semiconductor faces moderate supply risk due to policy-driven delivery uncertainty in upstream petrochemical feedstocks, with initial disruptions emerging within 14 days and full impact materializing within 98 days. ### Risk Propagation Pathway SCRT identifies a risk propagation path: Event -> Oil Products -> Naphtha/Ethylene -> Semiconductor-grade Chemicals -> Advanced Packaging Substrates -> 4G/5G Baseband Chips -> GCT Semiconductor Holding, Inc. SCRT, SupplyGraph.AI's supply chain risk tracking framework, leverages advanced algorithms to trace risk propagation paths. 4 continuously updated 24/7 proprietary databases + SCRT risk tracing algorithms → risk propagation path SCRT utilizes four proprietary databases to achieve this: a 400M+ global company database, a 1.5M+ industrial product database, a product dependency graph database that maps product compositions and production-stage consumables, and a 5M+ global historical event database capturing supply chain disruptions. By learning patterns from past disruptions and continuously tracking global events, SCRT matches real-time occurrences with historical cases to identify risks impacting GCT Semiconductor. It analyzes product dependency graphs to locate affected nodes and quantify risk exposure, propagating risk along these paths to derive a comprehensive impact assessment. All node relationships stem from genuine business dependencies between companies, and the path is constructed based on data-driven supply chain structures. ### Mechanism of Supply Chain Impact Ultimately, any geopolitical risk manifests in price signals, and the volatility triggered by the U.S. sanctions waivers on Russian and Iranian crude has rippled through GCT Semiconductor’s upstream supply chain. Crude oil prices swung from $102.01 per barrel on April 8 to $82.14 by June 22, while naphtha—a critical petrochemical feedstock—plummeted from $914.91 per metric ton to $706.54 over the same period. These fluctuations directly impacted downstream intermediates essential to semiconductor manufacturing, as shown in the following data: |Category| Product | Date | Price | |--------|----------|------|-------| |Energy| Crude Oil | 2026-04-08 | 102.01 USD/Bbl | |Energy| Crude Oil | 2026-04-23 | 92.78 USD/Bbl | |Energy| Crude Oil | 2026-05-08 | 99.87 USD/Bbl | |Energy| Crude Oil | 2026-05-23 | 100.80 USD/Bbl | |Energy| Crude Oil | 2026-06-07 | 91.59 USD/Bbl | |Energy| Crude Oil | 2026-06-22 | 82.14 USD/Bbl | |Energy| Naphtha | 2026-04-08 | 914.91 USD/T | |Energy| Naphtha | 2026-04-23 | 908.70 USD/T | |Energy| Naphtha | 2026-05-08 | 898.19 USD/T | |Energy| Naphtha | 2026-05-23 | 871.52 USD/T | |Energy| Naphtha | 2026-06-07 | 740.88 USD/T | |Energy| Naphtha | 2026-06-22 | 706.54 USD/T | |Metals| Silicon | 2026-04-08 | 8412.00 CNY/T | |Metals| Silicon | 2026-04-23 | 8443.64 CNY/T | |Metals| Silicon | 2026-05-08 | 8653.12 CNY/T | |Metals| Silicon | 2026-05-23 | 8463.00 CNY/T | |Metals| Silicon | 2026-06-07 | 8514.00 CNY/T | |Metals| Silicon | 2026-06-22 | 8537.50 CNY/T | The price collapse in crude and naphtha initially eased input cost pressures, but the erratic supply policy created delivery uncertainty that propagated along GCT’s dual exposure paths: one through naphtha-derived semiconductor-grade chemicals into advanced packaging substrates for 4G/5G baseband chips, and another via photoresists and specialty gases into wafer fabrication for RF transceivers. Each stage absorbed shocks with defined lags—naphtha to electronic chemicals took 2–4 weeks, chemicals to substrates added 3–6 weeks, and final chip integration required up to 8 weeks—cumulatively stretching the full传导 cycle to approximately 14 weeks. This supply-chain turbulence, driven more by policy-induced delivery constraints than pure cost shifts, is set to impose moderate supply risk on GCT Semiconductor within 14 weeks. ### Could Mitigation Strategies Fully Neutralize the Risk? At first glance, conventional supply chain resilience measures—such as multi-sourcing and strategic inventory buffers—might appear sufficient to insulate GCT Semiconductor from upstream volatility. However, this view underestimates the structural concentration and technical specificity embedded in semiconductor-grade chemical production. While GCT may source from multiple chemical suppliers, the feedstock base for high-purity naphtha and ethylene remains tightly linked to a limited set of crude oil refining hubs, many of which are directly exposed to geopolitical policy shifts. Inventory can smooth short-term demand spikes, but it cannot compensate for prolonged delivery uncertainty caused by inconsistent sanction enforcement or export licensing delays. Moreover, the capital-intensive, highly regulated nature of semiconductor-grade chemical synthesis limits rapid capacity reallocation or substitution, rendering traditional diversification tactics less effective in this context. ### Historical Evidence and Structural Dependencies Reinforce the Risk Contrary to the notion that GCT can easily sidestep upstream turbulence, empirical precedents underscore the fragility of tightly coupled semiconductor supply chains under geopolitical stress. The 2021 global chip shortage, for instance, was not triggered by a single plant outage but by a confluence of policy-driven disruptions—from pandemic-related lockdowns to export controls—that cascaded through feedstock and intermediate chemical layers, ultimately halting automotive and consumer electronics production worldwide [1]. Similarly, the Russia-Ukraine conflict disrupted European energy flows, spiking natural gas prices and forcing chemical producers to curtail output of critical precursors like ethylene and propylene, which feed directly into photoresists and specialty gases [2]. These cases align precisely with the SCRT-identified propagation pathway: **Oil Products → Naphtha/Ethylene → Semiconductor-grade Chemicals → Advanced Packaging Substrates → 4G/5G Baseband Chips → GCT Semiconductor**. Price volatility in crude oil rapidly transmits to naphtha, which—despite its declining nominal price—suffers from erratic availability due to policy-induced trade barriers. This uncertainty propagates with defined lags: 2–4 weeks from naphtha to electronic-grade chemicals, 3–6 weeks from chemicals to advanced packaging substrates, and up to 8 weeks for final integration into baseband chips. Over this 14-week (98-day) cycle, delivery disruptions compound, and inventory buffers deplete without replenishment certainty. Given GCT’s dual exposure—through both advanced packaging substrates and wafer fabrication inputs like photoresists and specialty gases—the company faces overlapping vulnerability nodes that cannot be decoupled through operational workarounds alone. ### Integrated Risk Assessment: Moderate but Material Impact Confirmed The U.S. sanctions waivers on Russian and Iranian crude oil, though designed to ease global supply tensions amid Middle East instability, have paradoxically introduced policy-driven volatility into petrochemical feedstock markets that directly impacts GCT Semiconductor Holding, Inc. Crude oil prices declined from **$102.01 to $82.14 per barrel** between April 8 and June 22, 2026, while naphtha—a critical petrochemical intermediate—fell from **$914.91 to $706.54 per metric ton** over the same period. Although silicon prices remained stable (hovering around **8,500 CNY/ton**), this stability is irrelevant to GCT’s primary risk vector: its dependence on naphtha-derived semiconductor-grade chemicals for advanced packaging substrates used in 4G/5G baseband chips. The supply chain’s structural concentration, combined with the 14-week cumulative lag across chemical synthesis, substrate manufacturing, and chip integration, means that policy-induced delivery uncertainty—not just cost fluctuations—drives risk accumulation. Historical disruptions confirm that such upstream shocks propagate rapidly through capital-intensive, technically rigid semiconductor value chains. While inventory and supplier diversification offer partial mitigation, they are insufficient to absorb systemic feedstock-level disruptions. Consequently, GCT Semiconductor faces a **moderate but material supply risk**, with tangible disruption likely to manifest within **98 days** of the initial policy event, consistent with a risk score of **0.75**.

The above event tracking and supply chain risk analysis for GCT Semiconductor Holding, Inc. are not conducted manually, but are automatically generated by SupplyGraph.ai's data Agents under the SCRT (Supply Chain Risk Trace) framework. ### **Drowning in fragmented risk signals—how do you make sense of them?** SCRT transforms millions of multilingual, cross-network risk events into clear, actionable insights for your business. Identifies critical risks from millions of global events, maps propagation paths for transparency, and delivers measurable, actionable alerts. Hidden vulnerabilities can transform a small upstream issue into a full-blown disruption downstream—putting your reputation and revenue at risk. ### **How does a distant event become your supply chain problem?** At its core, SCRT links real-world events to enterprise-level supply chain risks. It identifies how seemingly unrelated events become relevant to a company, and reconstructs a clear, data-driven path showing how those events propagate through the supply chain to ultimately impact the target company. Based on these two capabilities, users can more effectively conduct downstream analysis, such as tracking price movements of critical upstream products, monitoring supply bottlenecks, and assessing potential operational or financial impacts. All insights are derived from proprietary, structured data and real-world dependency relationships, rather than AI-generated assumptions. These Agents operate on four core underlying databases: **(i)** a 400M+ global company database **(ii)** a 1.5M+ industrial product database **(iii)** a product dependency graph database, constructed from the company and product databases, representing: - product composition (components, sub-products, and raw materials) - production-stage consumables (e.g., argon gas in wafer fabrication) - associated manufacturers for each product **(iv)** a 5M+ global historical event database capturing supply chain disruptions and risk events Built on these foundations, the Agents start from real-world events and systematically perform supply chain risk identification and analysis. ## Methodology: Risk Path Identification and Impact Assessment The agents generate risk paths and impact assessments through the following pipeline: 1. Learning patterns from historical supply chain disruption events 2. Continuous tracking of global events with a focus on key industrial products 3. Matching real-time events with historical cases to identify risks affecting **GCT Semiconductor Holding, Inc.** 4. Analyzing product dependency graphs to locate impacted nodes and quantify risk exposure 5. Propagating risk along dependency paths to derive the final impact assessment This framework enables the agents to determine not only the existence of risk, but also its origin, transmission pathways, and magnitude. ## Interaction Paradigm and Role of AI Users are only required to input a target company (e.g., **GCT Semiconductor Holding, Inc.**), after which the data agents autonomously execute the full analytical pipeline. Risk identification is grounded in real-world events. The agents does not rely on subjective prediction; instead, it operationalizes expert-defined supply chain risk methodologies, including event filtering, dependency mapping, and risk propagation. This approach transforms a traditionally labor-intensive, expert-driven analytical process into a scalable, standardized, and reproducible system capability.
