The semiconductor industry has long followed a well-defined cyclical structure. Typically, price declines lead to a contraction in capital expenditure, followed by inventory normalization and eventual recovery. This repeated pattern—comprising pricing correction, investment pullback, inventory adjustment, and eventual market rebound—continues to offer a relevant lens through which to interpret the current uncertain market environment.
As of April 2025, the industry faces a mix of conflicting signals. Concerns are rising that AI-related demand may have already peaked, while cautious optimism persists over a possible rebound in DRAM prices in the second half of the year. These market dynamics are further complicated by rising macroeconomic uncertainty, including renewed trade friction between the U.S. and China, reemerging tariff risks, and persistent inflationary pressure. In such a complex and volatile environment, the importance of cycle-based structural analysis has never been greater.
Viewed from a momentum perspective, the recovery in semiconductor equipment investment—marked by a rebound in year-over-year growth (measured on a 12-month moving average basis) beginning in mid-2024—can be interpreted as a potential sign of renewed demand. However, this apparent stability may be misleading. While global companies significantly curtailed their fab investments throughout the second half of 2023 and the first half of 2024, China moved in the opposite direction, intensifying state-led expansion efforts aimed at achieving semiconductor self-sufficiency.
This divergence in investment behavior has distorted the global capital expenditure landscape, potentially creating the impression of a broader recovery, while in reality the momentum remains concentrated in a single region driven by policy rather than market fundamentals.
Similarly, the recent uptick in DRAM pricing appears to be driven more by production cuts than demand-side momentum. Major suppliers have been deliberately scaling back output to manage inventory and support pricing. In this context, price rebounds not backed by end-market demand are unlikely to sustain a meaningful recovery in wafer procurement.
Simulation results—based on second-half projections—suggest that unless DRAM blended ASP increases by more than 20% quarter-over-quarter in both Q3 and Q4 2025, a meaningful upward inflection in the year-over-year pricing trend (on a 12-month moving average basis) remains improbable. This highlights the fragility of the current price recovery suggests that without a meaningful improvement in end-market demand—particularly for DRAM—wafer procurement for DRAM production is unlikely to recover in a sustained manner, regardless of supply-side actions.
As SEMI highlights in this Silicon Wafer Market Monitor Report, a deeper understanding of the wafer market requires a close examination of raw material inventory trends. The inventory behavior of memory makers—due to their dominant scale and transparency—is widely regarded as a proxy for broader semiconductor industry trends. Following the pandemic, memory makers' raw material stockpiles surged to levels equivalent to five times their historical average relative to sales. While these ratios were significantly reduced between 2023 and 2024, inventory levels still meaningfully exceed pre-pandemic norms. With leading players signaling further inventory drawdowns, there is little incentive to rebuild raw material stockpiles—including silicon wafers—unless there is clear evidence of sustained demand recovery.
This inventory dynamic is closely tied to wafer shipment growth. Historical data reveals a strong inverse relationship between raw material inventory-to-sales ratios at the top three memory makers—Samsung, SK hynix, and Micron—and wafer shipments. When this ratio declines year-over-year, wafer shipment growth typically improves. However, a slowdown in the pace of inventory ratio reduction could result in stagnant or declining wafer shipment growth in subsequent periods.
Moreover, even as these inventory ratios continue to decline, wafer average selling prices (ASPs) have yet to show signs of recovery. This decoupling of pricing from inventory adjustments reflects the presence of a structural imbalance in supply and demand. On the supply side, all top five global wafer producers have secured greenfield fab capacity and are prepared to scale production. With depreciation pressures mounting, they face strong incentives to maintain economically viable utilization rates, contributing to ongoing ASP erosion.
Meanwhile, chip capacity expansion in China—primarily driven by demand for 200mm applications—is adding further downward pressure. Chinese wafer suppliers, who already hold a meaningful share in China’s 200mm market, are now directing more of their investment toward 300mm wafer production—intensifying price pressure and adding to the longer-term competitive pressures facing global suppliers. This focus aligns with China’s broader push into mature process nodes, even as demand outside the region remains tepid. Accordingly, local Chinese wafer suppliers are competing aggressively on price, weakening the regional competitiveness of established global wafer players.
As a result, the competitive landscape is undergoing a structural shift: global wafer suppliers are contending with intensified price-based competition among themselves in non-China markets, while simultaneously coming under mounting pressure from Chinese local players within China. This dual-front competition highlights the threshold point the industry has reached—where traditional pricing models and market dynamics are being fundamentally challenged.
Moreover, long-term supply agreements (LTAs), once effective tools for pricing stability, are expected to gradually lose relevance. As semiconductor manufacturers—who purchase wafers under LTAs—move toward shorter-term and more customized purchasing models, and as pricing volatility increases, the incentive to commit to such agreements is projected to steadily diminish.
The market, therefore, is not yet in a phase of strong recovery but appears to be undergoing a structural transition defined by persistent imbalances. The full report presents three scenario-based outlooks centered on four key variables—DRAM pricing, inventory normalization, equipment investment, and China’s regional influence. The most probable scenario currently assumes modest growth in 2025–2026, a correction in 2027, and a recovery in 2028. Wafer shipment growth rates under this scenario are projected at +5.1%, +5.4%, –6.2%, and +9.8%, respectively.
However, even this base case remains vulnerable to potential macroeconomic disruptions. The large-scale tariff measures announced by the U.S. in April 2025 could trigger cascading effects across the ecosystem—from weakening enterprise demand and delaying infrastructure investments to softening DRAM prices and curbing wafer procurement. In past cycles, leading macro indicators such as the OECD Composite Leading Indicators (CLI) tended to lead DRAM price movements. If macro momentum slows, the market could deviate from the base case and move closer to the downside scenario. This downside scenario assumes weak or negative growth through 2026, a moderate recovery in 2027, and a stronger rebound by 2028 as supply-demand conditions begin to normalize.
The current market trajectory suggests limited room for either sharp declines or sharp rebounds. The next phase will depend on how four forces interact: DRAM price momentum, inventory rebalancing pace, regional investment activity, and policy risks. A clear inflection point will only emerge when these factors begin to align. In other words, a meaningful shift—either upward or downward—will only occur when these forces move in the same direction and reinforce one another. Ultimately, any directional shift—whether delayed or accelerated—will still unfold within the broader framework of the semiconductor cycle previously discussed. In that sense, these indicators do not reverse the cycle itself; they merely influence the timing and pace at which it plays out.
This article presents a summary of key insights from the Q1 2025 Market Update section of the SEMI’s Silicon Wafer Market Monitor Report, which is compiled in PowerPoint format and distributed as a PDF. In this edition, scenario-based analysis was used to navigate growing macroeconomic uncertainty and assess potential turning points in wafer demand. To support this analysis, the Market Update section presents 10 core quantitative charts and long-term data series dating back to 2000—particularly curated to visualize and analyze semiconductor revenue, investment, and pricing cycles in a single view.
Separate from this focused section, the full SEMI’s Silicon Wafer Market Monitor Report includes a much broader array of charts and indicators, providing a multi-dimensional analysis of how fundamental variables interact to shape the future of the silicon wafer industry. Rather than simply offering background explanation, the full report is intended to provide clear, data-driven insights that can support strategic thinking amid market uncertainty.
