According to the latest industry monitoring data from Thai Chip Value Network, the overall revenue of the Southeast Asian semiconductor market in the second quarter of 2026 grew 15% year-on-year, reaching approximately USD 28.5 billion, outperforming the global average growth rate (about 9%). The region has achieved double-digit growth for three consecutive quarters, mainly driven by surging demand for artificial intelligence (AI) chips and the continuous upgrade of automotive electronics.
AI Chip Demand Spurs Capacity Tightness
With the accelerated global AI infrastructure buildout, Southeast Asia, as a key hub for testing and packaging and some wafer manufacturing, directly benefits from outsourcing orders from major companies such as NVIDIA and AMD. Packaging and testing factories in Penang, Malaysia and the Eastern Economic Corridor (EEC) of Thailand achieved 93% capacity utilization in the second quarter, the highest in three years. The Thailand Semiconductor Association (TESA) pointed out that local advanced packaging (such as CoWoS and 3D packaging) capacity has been booked out until early 2027, driving the performance of related equipment and material suppliers.
Steady Growth in Automotive Electronics Demand
On the other hand, the penetration rate of new energy vehicles and smart cockpits continues to rise, driving steady growth in demand for automotive ICs (microcontrollers, power semiconductors, sensors). Revenue from automotive chip testing and packaging lines in Vietnam and the Philippines grew 18% and 12% respectively in the second quarter. Japanese and European carmakers are increasing their procurement share from Southeast Asia to diversify supply chain risks, further supporting the market.
Country Performance: Thailand and Malaysia Lead
- Thailand: Semiconductor exports reached USD 6.8 billion in Q2, up 16% YoY. Main drivers include hard disk drive ICs and automotive power modules. The Thailand Board of Investment (BOI) has approved several wafer fab expansion plans, with three new 8-inch fabs expected by 2027.
- Malaysia: The semiconductor industry contributes over 20% of the country's manufacturing GDP. Q2 revenue grew 14%, with logic chips and packaging/testing services performing best. The Penang state government announced the establishment of a semiconductor innovation park to attract AI chip design startups.
- Vietnam: Benefiting from order shifts from South Korean and Chinese players, Q2 semiconductor output grew 12%, mainly concentrated in testing, packaging, and assembly in Ho Chi Minh City and Da Nang. The Vietnamese government recently passed the Semiconductor Industry Development Strategy, targeting a 10% market share for self-designed chips by 2030.
- Singapore: As a regional R&D and headquarters hub, Q2 revenue grew 9%, relatively stable. However, local foundries (e.g., GlobalFoundries) are still at full capacity, with lead times for automotive and industrial chips exceeding 20 weeks.
Industry Insight: Sustained Supply Shortage, but Concerns Emerge
Despite the booming market, analysts remind investors to watch for the following risks:
- Inventory Adjustment Pressure: Demand recovery for consumer electronics (phones, PCs) remains sluggish. Inventory levels of some general-purpose MCUs and memory are still high, which may lead to price weakness in Q3.
- Geopolitical Uncertainty: US chip export controls on China may affect transshipment business in Southeast Asia. Electronics manufacturing service (EMS) factories in Thailand and Malaysia have started reviewing supply chain compliance.
- Talent Shortage: Semiconductor engineers and technicians face severe supply-demand imbalance in Southeast Asia. Labor costs in Thailand and Vietnam have risen 5-8%, potentially squeezing margins.
However, in the long run, structural demand from AI and automotive electronics will continue to support the Southeast Asian semiconductor market. The International Semiconductor Equipment and Materials Association (SEMI) estimates that Southeast Asia's semiconductor capital expenditure will reach USD 35 billion in 2026, up 20% YoY, with Thailand and Malaysia accounting for 70%. As supply chains regionalize, Southeast Asia is expected to become the world's third-largest semiconductor production cluster after Taiwan and South Korea within three years.
Investment Opportunities and Strategy Suggestions
The second half of the year enters the traditional peak season, but attention should be paid to possible order corrections in Q3. Recommended focus areas:
- Testing, Packaging, and Advanced Packaging Concept Stocks: Direct beneficiaries of the AI chip outsourcing wave, such as Thailand's Saha-Union and Malaysia's Inari Amertron.
- Power Semiconductors and IGBT Modules: Strong demand from automotive and green energy sectors; Thailand's Hana Microelectronics and Malaysia's Unisem are key targets.
- Equipment and Materials: Companies such as Thailand's WHA Group and Malaysia's Pentamaster benefit from the expansion wave.
Overall, the Southeast Asian semiconductor market is at a cyclical peak. Short-term fluctuations due to global macroeconomic volatility are possible, but medium-to-long-term growth momentum is clear. Investors should accumulate on pullbacks and focus on leading companies with technological moats and customer stickiness.
