Isopropanol Market Rebounds and Then Retreats in Q3; Volatile Trend Expected to Persist in Q4

【Introduction】In the third quarter of 2026, the domestic isopropyl alcohol (IPA) market exhibited a phased pattern of initial decline followed by recovery, peaking before pulling back. The market bottomed out in early July, rose to a quarterly high in mid-September, and subsequently entered a period of fluctuation. This strong price rebound was primarily driven by sustained increases in raw material costs—specifically acetone and propylene—while sluggish downstream demand consistently constrained further upside potential. The market’s core dynamic was characterized by intense competition between cost-driven pressures and weak demand.

I. From Low-Level Fluctuations to Peak-and-Pullback Driven by Cost Support

The domestic IPA market trended upward with fluctuations throughout Q3. In early July, the market was in a recovery phase following the deep adjustment seen in the first half of the year. Although maintenance shutdowns at some plants led to a slight contraction in supply, persistently weak downstream demand and strong resistance to higher prices kept values low. The Jiangsu market hit a quarterly low of 5,775 yuan/ton. Subsequently, rising costs provided solid floor support, leading to a gradual increase in market prices. However, due to consistently weak demand follow-through, combined with the official ramp-up of new capacity in early August—which effectively offset losses from maintenance—the supply landscape remained loose. Prices were trapped in a narrow trading range, bounded above and below.

In September, strengthened international crude oil prices and geopolitical factors triggered correlated rises in upstream benzene and propylene, driving sustained increases in the price of acetone, a key raw material. Acetone-route manufacturers faced sharply increased cost pressures and showed strong willingness to hold prices, pushing IPA prices up rapidly, with many regional markets setting new quarterly highs. However, limited acceptance of these high prices among downstream users led to reduced actual transaction volumes. By mid-month, as the rise in raw material prices slowed, IPA prices peaked and pulled back, transitioning into a consolidation phase.

II. Supply-Demand Landscape Remains Loose

In Q3, the overall supply landscape for the IPA industry remained relatively loose. However, operating rates diverged significantly between the two main production routes. For acetone-route plants, the surge in acetone prices far exceeded the rise in IPA prices, plunging these facilities into deep losses. Consequently, multiple units across the industry halted production or reduced output, dropping the utilization rate to approximately 41%. In contrast, propylene-route plants, which maintained acceptable profit margins, had a stronger incentive to increase loads, keeping their utilization rate around 64%. This effectively compensated for the volume lost from acetone-route plants, preventing any significant shortage in total market supply. On the demand side, activity remained tepid. Downstream factories primarily purchased on an urgent, small-lot basis. Especially after the rapid price surge, willingness to absorb high prices dropped sharply, leading to a clear slowdown in actual transactions and exerting continuous pressure on the upward momentum of IPA prices.

III. Diverging Profit Margins Between Production Routes

In Q3, strong support from the cost side was the primary driver behind the rise in IPA prices. Production costs for both routes increased significantly, but profitability outcomes diverged markedly.

• Acetone Route: In September, the increase in acetone prices vastly outpaced the rise in IPA market prices. The spread between the two narrowed rapidly to historic lows, causing a sharp spike in cost pressures for manufacturers. Gross production margins fell to -750 yuan/ton or even lower. Sustained losses forced some companies that relied on externally sourced acetone to halt operations for extended periods, clearly suppressing overall industry operating rates.
• Propylene Route: Although rising propylene prices also increased production costs, this route benefits from lower unit consumption of propylene. As IPA market prices rose, the profit margin for propylene-route plants actually expanded. Driven by this profit advantage, propylene-route plants maintained high-load operations, serving as a stable source of market supply.

IV. Market Moves Forward Amid Weak Equilibrium

Looking ahead to Q4, the IPA market is expected to continue its pattern of loose supply-demand balance, cost-supported floors, and range-bound fluctuations.

• Supply Side: While acetone-route units may continue to operate at low loads due to loss constraints, the high operating rates of propylene-route plants are likely to persist. Coupled with the gradual full-scale operation of previously added capacity, total market supply will remain ample, making significant supply contractions unlikely.
• Demand Side: A substantial improvement in demand is not anticipated, as incremental growth in traditional downstream domestic consumption remains limited. Although exports show some resilience, overseas markets have limited ability to absorb large volumes, meaning export quantities are unlikely to see dramatic growth. Overall demand support remains weak.
• Cost Side: Raw material trends will be critical. If input costs retreat, IPA will lose its cost-based support; if they remain firm, prices will likely oscillate within a defined range.

Market participants should closely monitor raw material volatility and downstream inventory levels as key indicators for future price direction.
