In an AI-driven market, restructuring momentum is building in Japan’s chemicals industry
Morgan Stanley believes the petrochemical cycle is nearing a bottom and industry restructuring is accelerating, while AI semiconductors, recovery in 300mm silicon wafers, and aerospace carbon fiber demand provide structural stock-picking opportunities.
- The industry view for petrochemical majors is Attractive, with recommendations for Sumitomo Chemical, Mitsui Chemicals, and Asahi Kasei, as valuation metrics remain low and the sector is considered undervalued overall.
- The industry view for electronic chemicals is In-Line; AI semiconductor expansion combined with a gradual recovery in traditional semiconductor demand supports the sector, and 300mm silicon wafers continue their recovery trend though inventories remain high.
- The industry view for fine chemicals is In-Line; carbon fiber composites are seeing significant revenue improvement driven by a full recovery in aircraft applications, and Toray is listed as a Top Pick.
- Japan’s petrochemical industry is shifting from cycle-sensitive basic chemicals toward high-margin functional chemicals, with ethylene plant integration and capacity optimization as core themes.
Report interpretation
Overview
This report is Morgan Stanley’s industry research on the Asian and Japanese chemicals sectors, with the core theme that industry restructuring is accelerating in an AI-driven market environment. The report covers three main lines—petrochemical majors, electronic chemicals, and fine chemicals—and selects stocks using indicators such as global chemicals market-cap performance, valuations, earnings forecasts, ethylene supply and demand, semiconductor materials, PVC, and aerospace demand for carbon fiber.
Core views
The report’s most positive view is concentrated on petrochemical majors: although petrochemical demand and ethylene operating rates remain weak, prices and spreads may already be near the bottom, and sentiment is improving with China’s anti-involution policy, signs of reductions in South Korean naphtha crackers, and restructuring of Japanese olefins facilities. Electronic chemicals remain neutral with structural opportunities, as AI semiconductor expansion and traditional semiconductor recovery support demand, though silicon wafer inventories remain high. Fine chemicals are also In-Line, with recovery in aerospace applications and general industrial demand such as pressure vessels driving medium-term tightening in carbon fiber supply and demand.
Analysis framework
The report combines industry conditions, supply-demand analysis, valuation, earnings forecasts, and corporate portfolio transformation: it first compares the market cap of global chemical companies and the performance of Japanese chemical subsectors, then tracks ethylene operating rates, petrochemical prices and spreads, semiconductor material demand, PVC supply and demand, carbon fiber inventories, and aircraft deliveries, and finally maps these to stock ratings, target prices, and recommended portfolios.
Methodology notes
Ethylene supply and demand, operating rates, prices, and spreads
It assesses whether the petrochemical cycle is bottoming by examining global ethylene supply and demand, Asian petrochemical product prices and spreads, and Japan’s domestic ethylene production and operating rates.
Facility integration and capacity optimization
It focuses on the progress of integration among Japanese petrochemical companies at olefins complexes such as Kashima, Chiba, Kawasaki, and Keiyo, as well as the path of transformation from basic chemicals to functional chemicals.
AI semiconductors and electronic chemicals
It maps AI semiconductor expansion, traditional semiconductor recovery, 300mm silicon wafer supply and demand, and polarizer materials to opportunities for electronic chemicals companies.
P/E, P/CF, EV/EBITDA, P/B, dividend yield, core operating profit
It uses FY26-FY28 earnings forecasts, market consensus, valuation multiples, dividend yields, and FX sensitivity to compare the investment attractiveness of covered companies.

Impact & implications
The report’s core investment implication is that Japan’s chemicals sector should not be viewed solely as a traditional cyclical sector; industry restructuring, product mix upgrades, and demand for AI-related materials are changing the earnings structure. Valuation recovery for petrochemical majors depends on prices and spreads bottoming out, facility integration being realized, and a higher share of functional chemicals; opportunities in electronic chemicals are more stock- and material-specific; in fine chemicals, the recovery of carbon fiber aerospace and industrial applications may lead to medium-term tightening in supply and demand.
Risks
- Petrochemical demand and ethylene operating rates remain persistently weak, and prices and spreads fail to bottom out and recover as expected.
- New capacity in China, weak demand, or China’s anti-involution policy proves less effective than expected, weakening support for Asian petrochemical product prices.
- Integration of Japanese olefins facilities and industry restructuring progress more slowly than expected, preventing realization of cost optimization and capacity rationalization.
- Customer inventories of semiconductor materials remain high, and AI semiconductor demand fails to sufficiently drive recovery in traditional semiconductors and 300mm wafers.
- US PVC prices, housing starts, and the mortgage-rate environment deteriorate, affecting Shintech’s earnings recovery.
- Recovery in aerospace deliveries or general industrial demand falls short of expectations, delaying tightening in carbon fiber supply and demand.
- Execution of portfolio transformation, M&A integration, or growth investment falls short of expectations.
What to watch
- Whether Asian petrochemical product prices and spreads remain steadily above the bottom.
- Changes in global ethylene supply and demand, operating rates, and domestic ethylene capacity utilization in Japan.
- Whether China’s anti-involution policy and reductions in South Korean naphtha crackers lead to meaningful supply contraction.
- Progress of restructuring projects such as Chiba Ichihara, Keiyo Ethylene, and production optimization in western Japan.
- Monthly inventory levels, shipments, and capacity trends for 300mm silicon wafers.
- The spread of AI semiconductor demand into subsegments such as electronic chemicals, polarizers, and LiB materials.
- US domestic and export PVC prices, North American PVC supply and demand, US housing starts, and 30-year mortgage rates.
- Aircraft deliveries by Boeing and Airbus, carbon fiber inventory ratios, ASP, and pressure vessel demand.
