Silicon Wafer Quotes See First Rise in 3 Years: Semiconductor Material Deflation Ends, Chip Cost Side to Shift in H2 2026

Silicon Wafer Quotes See First Rise in 3 Years: End of Semiconductor Material Deflation, Chip Cost Side to Shift in H2 2026

In early August 2026, a highly significant signal emerged from the upstream global semiconductor supply chain: semiconductor silicon wafers, a major component of wafer manufacturing costs, finally ended a nearly three-year price decline and saw their first substantial price increase. According to the latest industry chain reports, Japanese silicon wafer giant SUMCO and several leading suppliers have notified downstream wafer foundries and IDMs of plans to raise quotes for 12-inch advanced-node wafers in the second half of 2026, with initial estimates of a 5% to 10% increase. This is the first stabilization and rebound in silicon wafer quotes since the market entered a destocking downturn in the second half of 2023, officially ending the "deflation era" for basic semiconductor materials.

Silicon Wafer Prices Bottom Out and Rebound: Inflection Point Established

As the cornerstone of chip manufacturing, silicon wafer price trends have long been seen as a barometer of the semiconductor industry's health. During the global chip shortage of 2021-2022, wafer prices soared. However, with the global consumer electronics market weakening in 2023, wafer foundry utilization rates declining, and high silicon wafer inventories, prices experienced a continuous decline over several quarters.

Entering 2026, this situation has fundamentally reversed. Industry analysis indicates the core drivers of this price increase are twofold:

• Booming Advanced Node Demand: With the accelerated penetration of generative AI applications into edge devices (AI phones, AI PCs) and exponentially growing demand for high-performance computing (HPC) chips in global data centers, foundry giants like TSMC are running at full capacity for advanced nodes such as 3nm and 2nm. These nodes demand extremely high purity, flatness, and low defect rates, leading to relatively lower yields and objectively consuming large amounts of high-quality wafer capacity.
• Proactive Production Control by Wafer Makers: During the past two-year downturn, the world's top two silicon wafer suppliers, Shin-Etsu Chemical and SUMCO, adopted conservative capacity expansion strategies and even shut down some older production lines. As existing inventories are depleted and new capacity remains limited, wafer makers' bargaining power has significantly strengthened.

Cost Transmission Mechanism Activated: IC Quotes and Wafer Foundries Face New Pressure

As the core raw material for wafer manufacturing, silicon wafers typically account for about 15% to 20% of total wafer cost. Rising wafer prices will undoubtedly directly increase manufacturing costs for wafer foundries and IDM manufacturers. For the current semiconductor market, this change will trigger a chain reaction.

First, for mature nodes (e.g., 28nm and above), ongoing capacity competition in the market creates uncertainty about whether foundries can fully pass on the increased wafer costs to downstream IC design companies. This could squeeze the gross margins of mature-node foundries. However, for advanced nodes, where supply and demand are in a tight balance, leading foundries like TSMC are highly likely to pass upstream costs downstream by adjusting foundry quotes or reducing discounts.

Second, for IC design companies, this means increased pressure on the chip cost side. During the two-year wafer deflation period, some analog chip and consumer-grade MCU manufacturers relying on mature nodes benefited from falling raw material costs. With the reversal in wafer prices, coupled with recent price rebounds in some power devices and niche memory chips, gross margin divergence within the IC design sector will intensify. Leading chip makers with strong pricing power will cope easily, while smaller firms relying on low-price competition face the risk of profit erosion from both ends.

SGX Semiconductor Equipment Stocks and Industry Chain Investment Opportunities

From a capital market perspective, the rise in silicon wafer prices not only confirms the overall semiconductor market recovery but also brings new investment logic for related industry chains. For investors on the Singapore Exchange (SGX), focus should be on two main themes:

First, valuation repair in the semiconductor materials and equipment supply chain. Higher wafer prices will directly boost wafer manufacturers' revenue and profitability, while capacity expansion relies on semiconductor equipment suppliers. SGX-listed semiconductor equipment and component suppliers with deep involvement in crystal growing furnaces, slicing equipment, or grinding and polishing tools may see a new order cycle.

Second, watch for cost-offsetting effects from advanced packaging. With rising silicon wafer costs, maximizing chip output per wafer becomes crucial. This accelerates the adoption of advanced packaging technologies like Chiplet and CoWoS. Combining multiple small chips through advanced packaging can effectively reduce reliance on large-area advanced-node wafers, achieving cost reduction and efficiency gains amid rising material costs.

Industry Outlook: Semiconductor Market Enters New Phase in H2 2026

In summary, the start of a silicon wafer price upcycle in August 2026 marks a significant milestone in industry fundamentals recovery. It indicates that the global semiconductor market has completely emerged from the 2023-2024 destocking shadow and is moving into an upcycle driven by synchronized supply and demand.

For procurement decision-makers, now is a critical window to lock in long-term silicon wafer and foundry capacity. With the peak consumer electronics season in the second half of the year and sustained AI computing demand, the tightness in wafer and chip capacity may intensify further. For investors, close attention should be paid to subsequent quarterly earnings guidance on foundry gross margins and IC design companies' cost control capabilities.

The end of the silicon wafer deflation era signals a restructuring of competitive logic in the semiconductor market. With stronger cost-side support, chip price trends will be more resilient, and the global semiconductor market is poised for a new landscape of rising volumes and prices in the second half of 2026.
