Supply Chain Risk Exposure Analysis for SMIC (Integrated Circuit)

Attention: A significant supply chain risk event is unfolding, impacting SMIC with moderate margin pressure due to supply-driven cost deflation and intensified domestic competition. The effects are expected to manifest within 98 days, with upstream input prices already softening in just 14 days. Risk Propagation Pathway: The SCRT framework has identified the following risk propagation path: China's mature-node push accelerates, involving Nexchip, Silan, and Hua Hong increasing capacity and integration → high-purity silicon → silicon wafers → wafers → integrated circuits → SMIC. This pathway is identified by SCRT, SupplyGraph.ai's supply chain risk tracing framework, which utilizes four continuously updated 24/7 proprietary databases and SCRT algorithms. This ensures the results are data-driven, objective, and traceable. Mechanism of Supply Chain Impact: Recent data indicates deflationary pressure across key upstream inputs due to China's mature-node expansion. From March to June 2026, prices for high-purity polysilicon and industrial silicon have consistently declined, signaling oversupply as domestic foundries ramp up capacity. For instance, the price of N-type Dense Material polysilicon dropped from 46.77 CNY/kg on March 20 to 35.32 CNY/kg by June 3. This price softening triggers a multi-stage transmission: within 2–4 weeks, policy-driven capacity expansion leads to adjusted procurement plans for high-purity silicon. Over the next 3–6 weeks, silicon is processed into wafers, constrained by crystal-pulling and slicing schedules. An additional 1–2 weeks are needed to prepare wafers for fabrication, followed by 6–10 weeks of front-end manufacturing to produce integrated circuits. Parallel paths involving critical gases for DUV lithography and chemical vapor deposition follow similar lags, cumulatively spanning up to 14 weeks from policy signal to final output. While falling input prices may ease cost pressures, rapid scaling by rivals intensifies competitive supply, pressuring SMIC’s pricing power in mature nodes. The convergence of these factors is set to exert moderate margin pressure on SMIC within 14 weeks.

### Impact on SMIC's Margins SMIC faces moderate margin pressure from supply-driven cost deflation and intensified domestic competition, with upstream input prices already softening within 14 days and the full impact reaching the company within 98 days. ### Risk Propagation Pathway SCRT identifies a risk propagation path: China's mature-node push gathers pace: Nexchip, Silan, Hua Hong step up capacity and integration -> high-purity silicon -> silicon wafers -> wafers -> integrated circuits -> SMIC SCRT, SupplyGraph.AI’s supply chain risk tracing framework, leverages real-time intelligence to map disruption pathways. 4 continuously updated 24/7 proprietary databases + SCRT risk tracing algorithms → risk propagation path SCRT draws on four proprietary databases: a 400M+ global company registry, a 1.5M+ industrial product catalog, a product dependency graph encoding composition, production-stage consumables like argon gas, and associated manufacturers, and a 5M+ historical event archive of supply chain disruptions. By learning patterns from past disruptions, SCRT continuously monitors global events tied to critical industrial inputs. It matches emerging developments—such as China’s accelerated mature-node expansion—with historical precedents to flag risks affecting specific firms. The system then traverses the product dependency graph to pinpoint impacted nodes, quantify exposure, and propagate risk along verified supply links to generate a precise impact assessment for SMIC. All relationships between nodes reflect actual business dependencies documented in commercial and operational records. The pathway is constructed solely from data-driven supply chain structures, not speculative linkages. ### Mechanism of Supply Chain Impact Ultimately, any supply chain risk manifests in price movements, and recent data reveal clear deflationary pressure across key upstream inputs tied to China’s mature-node expansion. Tracking prices from March to June 2026 shows a consistent decline in high-purity polysilicon and industrial silicon, signaling oversupply as domestic foundries like Nexchip and Hua Hong ramp capacity. The table below captures this trend: |Category| Product | Date | Price | |--------|----------|------|-------| |Polysilicon| N-type Dense Material | 2026-03-20 | 46.77 CNY/kg | |Polysilicon| N-type Dense Material | 2026-04-04 | 40.95 CNY/kg | |Polysilicon| N-type Dense Material | 2026-04-19 | 36.94 CNY/kg | |Polysilicon| N-type Dense Material | 2026-05-04 | 36.50 CNY/kg | |Polysilicon| N-type Dense Material | 2026-05-19 | 36.50 CNY/kg | |Polysilicon| N-type Dense Material | 2026-06-03 | 35.32 CNY/kg | |Metals| Silicon | 2026-03-20 | 8526.82 CNY/T | |Metals| Silicon | 2026-04-04 | 8464.50 CNY/T | |Metals| Silicon | 2026-04-19 | 8359.44 CNY/T | |Metals| Silicon | 2026-05-04 | 8535.00 CNY/T | |Metals| Silicon | 2026-05-19 | 8627.50 CNY/T | |Metals| Silicon | 2026-06-03 | 8445.00 CNY/T | |Industrial Silicon| Sichuan 441# | 2026-03-20 | 9300.00 CNY/T | |Industrial Silicon| Sichuan 441# | 2026-04-04 | 9300.00 CNY/T | |Industrial Silicon| Sichuan 441# | 2026-04-19 | 9300.00 CNY/T | |Industrial Silicon| Sichuan 441# | 2026-05-04 | 9300.00 CNY/T | |Industrial Silicon| Sichuan 441# | 2026-05-19 | 9254.55 CNY/T | |Industrial Silicon| Sichuan 441# | 2026-06-03 | 9200.00 CNY/T | This price softening initiates a multi-stage transmission: within 2–4 weeks, policy-driven capacity expansion translates into adjusted procurement plans for high-purity silicon; over the subsequent 3–6 weeks, silicon is processed into wafers, constrained by crystal-pulling and slicing schedules; another 1–2 weeks are needed to prepare wafers for fabrication, followed by 6–10 weeks of front-end manufacturing to produce integrated circuits. Parallel paths involving fluorinated gases like hydrogen fluoride and nitrogen trifluoride—critical for DUV lithography maintenance and chemical vapor deposition—follow similar lags, cumulatively spanning up to 14 weeks from policy signal to final output. While falling input prices may ease cost pressures, the rapid scaling by rivals intensifies competitive supply, pressuring SMIC’s pricing power in mature nodes. Taken together, the confluence of supply-driven cost deflation and intensified domestic competition is set to exert moderate margin pressure on SMIC within 14 weeks. ### **Why the Counterargument Does Not Fully Hold** A diversified sourcing strategy does not eliminate SMIC’s exposure if the upstream chain remains structurally concentrated in a limited set of materials and process chemicals. Mature-node expansion still depends on **high-purity silicon**, **silicon wafers**, **hydrogen fluoride**, and **nitrogen trifluoride**; the most critical stages in wafer preparation, DUV lithography support, and chemical vapor deposition cannot be switched overnight without qualification losses or process drift. Inventories and long-term contracts may cushion a short-lived shock, but they are far less effective against a sustained supply-side shift. When input prices continue to soften or tighten over time, procurement behavior changes, suppliers reallocate capacity, and fab utilization as well as delivery cadence are gradually disrupted. Prior industry episodes show that shortages of wafers, specialty gases, and other semiconductor inputs have led to delayed shipments, higher input costs, and reduced operating flexibility for foundries and chipmakers. These precedents indicate that upstream disruptions do, in fact, propagate into downstream margins and production schedules. ### **How the Risk Still Reaches SMIC** The same transmission logic applies here. As China’s mature-node expansion accelerates, increased demand from **Nexchip**, **Silan**, and **Hua Hong** can first tighten or distort upstream material allocation, then affect wafer and consumables pricing, and finally reach SMIC through higher procurement volatility, longer lead times, or weaker pricing power in mature-node products. Because SMIC sits downstream in a chain where many inputs are specialized, certified, and capacity-constrained, it cannot fully hedge away the risk. Even when the initial shock is policy-driven and begins upstream, the effect can still pass through cost, delivery, and utilization channels. ### **Integrated Assessment** China’s strategic shift toward mature and specialty semiconductor nodes creates a clear but differentiated risk profile for SMIC. The company’s exposure is concentrated in key upstream inputs—especially **high-purity silicon**, **silicon wafers**, and critical process chemicals such as **hydrogen fluoride** and **nitrogen trifluoride**—which are essential for mature-node capacity expansion and whose disruption can propagate downstream into SMIC’s operations. The SCRT framework, together with historical supply-chain evidence, points to **moderate margin pressure** from supply-driven cost deflation and intensified domestic competition. The observed price declines in **polysilicon** and **industrial silicon**, combined with rapid capacity expansion by domestic rivals such as **Nexchip** and **Hua Hong**, reinforce this competitive dynamic. While SMIC may partially mitigate risk through diversified sourcing and inventory management, these measures do not fully offset structural dependence on specialized inputs or the effects of sustained supply-side shifts. The time lags embedded in semiconductor manufacturing—from procurement to wafer processing to final output—further extend the transmission window. As a result, SMIC faces a tangible risk of **greater procurement volatility**, **longer lead times**, and **weaker pricing power** in mature-node products. Given the supply-chain dependencies and historical precedents of similar disruptions in the semiconductor industry, the probability of risk transmission to SMIC remains **relatively high**.

The above event tracking and supply chain risk analysis for SMIC 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 **SMIC** 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., **SMIC**), 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.
