In 2026, the explosive growth of AI chips contrasts sharply with the weak demand for traditional consumer electronics, intensifying inventory differentiation. As a key node in the global semiconductor supply chain, Singapore's inventory dynamics not only reflect the local market conditions but also foreshadow global trends. For example, the capacity utilization of wafer foundries, order saturation of packaging & testing companies, and inventory turnover rates of material suppliers have all become important indicators for measuring the inventory cycle. Currently, the industry is gradually transitioning from the high inventory stage, but different segments show varying performances, bringing opportunities and challenges to market participants.

Inventory Dynamics in Singapore's Semiconductor Market, September 2026

In September 2026, the inventory levels in Singapore's semiconductor market show structural differentiation. In the AI chip sector, due to giants like NVIDIA continuously driving computing power demand, the inventory of advanced-process wafers is at a healthy level, with some manufacturers even showing signs of restocking. However, the inventory of traditional consumer electronics chips such as smartphones and PC-related chips remains high, leading to fluctuations in the capacity utilization of mature processes. According to industry analysis, the inventory turnover days of Singapore's wafer foundries have decreased compared to the previous month, indicating an accelerated destocking process. Specifically, 8-inch wafer inventory has dropped by about 5%, while 12-inch advanced-process inventory remains basically stable. This differentiation mainly stems from the surge in demand for AI training chips and the slow recovery of consumer electronics demand. In addition, the inventory pressure in the packaging & testing segment has eased, with some companies starting to adjust capacity to match AI chip orders, demonstrating the flexibility of the supply chain.

Sub-sector Analysis of Inventory Levels

  • Wafer Foundry Inventory: Advanced processes (7nm and below) maintain low inventory, with capacity utilization above 90%, mainly benefiting from AI chip orders. Mature processes (28nm and above) have slightly decreased inventory, but some manufacturers still face excess pressure.
  • Packaging & Testing Inventory: AI chip packaging & testing demand is strong, inventory turnover accelerates, while traditional chip packaging & testing inventory remains high, putting price pressure.
  • Material Inventory: Silicon wafer and photoresist inventory have increased due to capacity expansion, but demand for high-end materials is stable, keeping prices firm.

Price Trend Analysis: Revaluation of Wafer and Packaging & Testing Prices

In September 2026, the price trends in Singapore's semiconductor market show a "heaven and hell" situation. Driven by AI, advanced-process wafer prices continue to rise, while mature-process prices show differentiation. Wafer foundries have raised quotations to meet AI chip demand, with price increases of 10%-15% for some high-end processes. The packaging & testing segment also benefits from AI chip demand, with prices rebounding, especially for high-density packaging technologies. However, traditional chip packaging & testing prices remain sluggish, leading to differentiated industry profit margins. This price revaluation reflects the market's re-pricing of AI demand and also highlights the adjustment pressure on the supply chain.
