New Observations on Chip Inventory Cycle: In-depth Analysis of Inventory Levels and Price Trends in Singapore's Semiconductor Market for October 2026
In October 2026, the global semiconductor market is undergoing a profound transformation in its inventory cycle. As a core hub for Asia's semiconductor industry, Singapore's inventory situation not only reflects regional market dynamics but also serves as a bellwether for the global semiconductor industry. This article will deeply analyze the current inventory levels, price trends, and underlying industrial logic of Singapore's semiconductor market, providing valuable references for industry participants and investors.
Singapore Semiconductor Market Inventory Status: Clear Divergence Trends
According to the latest market data, Singapore's semiconductor market in October 2026 shows a clear inventory divergence trend. AI chip inventories are at historical lows, while some traditional memory chip inventories have rebounded. This divergence reflects structural changes in demand across different application areas and indicates that the semiconductor market is entering a new adjustment cycle.
As the world's third-largest semiconductor manufacturing center, Singapore's inventory situation has a significant impact on the global supply chain. Currently, the overall inventory turnover days for local semiconductor enterprises in Singapore have slightly decreased from 42 days to 40 days compared to the previous month, but remain higher than the 38 days in the same period of 2025. This data indicates that although inventory pressure has eased, the market is still in the adjustment phase after destocking.
AI Chip Inventory: Continued Tightness, Firm Prices
In the AI chip sector, the inventory tightness in Singapore's market continues. Inventory turnover days for high-performance computing GPUs and specialized AI accelerators have fallen below 30 days, reaching a new historical low. This tight situation is mainly due to the explosive growth of AI applications and the relatively limited capacity of advanced process nodes.
Singapore-based AI chip design companies report that the current lead time from order to delivery has extended to 16-20 weeks, an increase of about 4 weeks compared to the end of 2025. This supply tightness has directly driven continuous price increases for AI chips, with high-end AI processors rising 15%-20% year-on-year, and this situation is unlikely to ease in the short term.
Notably, the AI chip market is also showing increasing divergence. General-purpose AI chips face inventory tightness, while AI-specific chips for certain domains have relatively stable inventories. This divergence reflects the trend of AI applications moving from general-purpose to specialized development, and indicates that future competition in the AI chip market will become more segmented.
Automotive Chip Inventory: Moderate Recovery, Stabilizing Prices
In contrast to AI chips, automotive chip inventories are showing a moderate recovery trend. Data from the Singapore Semiconductor Industry Association shows that inventory turnover days for automotive MCUs and power semiconductors increased from 35 days last month to 38 days, but remain at healthy levels.
This change is mainly influenced by two factors: on one hand, global automotive production has fully recovered from the pandemic, with supply chains gradually stabilizing; on the other hand, the incremental demand from increased new energy vehicle penetration has partially offset the slowdown in traditional automotive chip demand. After the rapid price increases in the early stages, automotive chip prices have now stabilized, with some products even showing slight price corrections.
Singapore-based automotive chip distributors report that although inventories have increased, automotive-grade chips still face high certification thresholds and long delivery cycles, with market supply and demand remaining in a tight balance. Especially high-performance automotive AI chips and power semiconductors continue to face supply constraints.
Memory Chip Inventory: High-Level Decline, Price Divergence
The memory chip market shows the most significant inventory changes. Inventory turnover days for DRAM and NAND Flash have decreased from 55 days and 60 days in the previous period to 48 days and 53 days respectively, but remain above historical averages. This change reflects the trend of memory chips gradually declining from the inventory peak at the end of 2025.
Memory chip price trends show clear divergence. High-end server DRAM prices remain firm, up 8% year-on-year; while consumer-grade DRAM prices have corrected, down 3% year-on-year. The NAND Flash market also shows divergence, with enterprise SSD prices stable while consumer product prices have declined.
Singapore-based memory chip traders analyze that the decline in memory chip inventories is mainly influenced by the slowdown in data center construction and weak consumer electronics demand. As cloud service providers adjust inventory strategies and consumer replacement cycles extend, the memory chip market is facing structural adjustments.
Wafer Foundry Inventory: Mature Process Excess, Advanced Process Tight
In the wafer foundry sector, inventory conditions show clear process node divergence. Mature process nodes (28nm and above) inventory turnover days have risen to 45 days, showing certain excess pressure; while advanced process nodes (7nm and below) inventory turnover days remain at a tight level of around 35 days.
Singapore-based wafer foundries report that the increase in mature process inventories is mainly due to the slowdown in consumer electronics demand and capacity expansion. To address this situation, some manufacturers have begun adjusting capacity allocation, shifting more resources toward automotive chips and industrial control chip applications.
The tight situation in advanced process inventories is unlikely to ease in the short term. Capacity utilization at Singapore's advanced process foundries remains above 95%, with delivery cycles extended to over 20 weeks. This tight situation is mainly driven by strong demand for AI chips, high-performance computing, and 5G equipment.
Packaging and Testing Industry Inventory: Moderate Adjustment, Slight Price Increases
The packaging and testing industry inventory is in a moderate adjustment state overall. Inventory turnover days for Singapore-based packaging and testing companies remain around 38 days, basically unchanged from last month. After the rapid price increases in the early stages, packaging and testing prices now show a moderate upward trend, with quarterly increases of about 2%-3%.
Inventory changes in the packaging and testing industry are closely related to downstream application demand. AI chip and automotive chip packaging and testing demand is strong, with inventory turnover days of only around 30 days; while consumer electronics packaging and testing demand is relatively weak, with inventory turnover days reaching 45 days. This divergence has prompted packaging and testing companies to accelerate product structure adjustments and increase investment in high-end packaging technologies.
Impact of Inventory Cycle on Market and Future Trends
The current changes in the semiconductor inventory cycle have multiple impacts on the market. In terms of prices, AI chip and automotive chip prices continue to rise, while memory chip and some mature product prices have fallen; in terms of supply chains, delivery cycles have extended, with both tight supply and excess coexisting, showing clear market divergence; in terms of investment, capital is accelerating toward AI chip, advanced process, and high-end packaging sectors.
Looking ahead, the semiconductor inventory cycle will show the following trends:
- AI chip inventory tightness will continue: As AI applications deepen and become more widespread, demand for high-performance computing chips will remain strong, and with limited expansion of advanced process capacity, the tight AI chip inventory situation is expected to continue until 2027.
- Automotive chip inventory will remain stable: Increased penetration of new energy vehicles and enhanced smart driving features will support automotive chip demand, with inventories expected to remain at healthy levels.
- Memory chip inventory will gradually return to normal: As cloud service providers and terminal manufacturers adjust inventory strategies, memory chip inventories are expected to return to normal levels in the first quarter of 2027.
- Mature process inventory pressure will ease: Recovery in consumer electronics demand and capacity adjustments will help ease mature process inventory pressure, with supply-demand balance expected to be achieved by mid-2027.
