In early September, geopolitical tensions drove international crude oil prices sharply higher, pushing up the costs of key isopropanol feedstocks, including acetone and propylene. Under mounting cost pressure, isopropanol producers raised their offers, driving prices higher.

As of the latest market assessment, the Jiangsu isopropanol market was trading at RMB 7,950–8,050/MT, up 6.31% from the beginning of September.

However, the price increase has not been accompanied by a meaningful recovery in demand. The current market is therefore characterized by a clear tug-of-war between strong cost support and weak downstream demand.

I. Strong Cost Support Drives Isopropanol Prices Higher

On the raw material side, the acetone market has maintained a strong upward trend. The continued strength of international crude oil prices has supported upstream benzene and propylene prices, further strengthening cost support for isopropanol producers.

At the same time, acetone supply remains relatively tight. Sellers are showing a stronger willingness to hold prices, while some downstream plants have entered the market to replenish inventories through bidding, increasing spot market activity and pushing transaction prices higher.

Propylene, another major feedstock for isopropanol production, has also strengthened amid tighter supply and geopolitical risk premiums. The combined increase in acetone and propylene costs has significantly increased production pressure on isopropanol plants and widened industry losses.

Against this backdrop, producers have raised their offers to ease margin pressure. Market sellers have also become increasingly reluctant to sell at lower prices, resulting in a clear upward shift in market negotiations.

However, downstream buyers remain cautious about accepting higher prices. Most purchases are limited to immediate requirements, while large-scale stockpiling remains uncommon.

As a result, the market is showing a typical pattern of rising prices but declining trading volumes. Strong cost support is pushing prices higher, but weak demand is limiting actual transaction activity.

II. Lower Operating Rates Provide Limited Supply Support

On the supply side, the average operating rate of the domestic isopropanol industry fell to around 44% in early September, significantly below the highs recorded in August.

The decline in operating rates is mainly attributable to two factors.

First, high acetone prices have placed significant pressure on producers that rely on externally sourced raw materials. Some companies have been operating at a loss for an extended period and have responded with temporary shutdowns or production cuts to reduce operating risks.

Second, several plants have entered scheduled maintenance periods, with some shutdowns expected to last approximately 10–15 days, further reducing current production.

However, the reduction in operating rates has not resulted in a significant tightening of overall supply. Previously added production capacity is gradually returning to normal operations, largely offsetting the losses from existing capacity.

Meanwhile, downstream demand remains weak, and buyers are mainly purchasing on an as-needed basis. Spot market turnover is relatively slow, while inventories remain generally adequate.

Therefore, although operating rates are low, the combination of weak demand and relatively sufficient spot availability means that the supply side currently provides limited support for high isopropanol prices.

III. Weak Demand Limits Further Price Gains

Demand remains the main factor restricting the isopropanol market.

In traditional industrial solvent applications, including coatings, inks and daily chemical products, downstream consumption remains relatively weak. The lingering effects of the traditional off-season and sluggish activity in some end-use industries have reduced purchasing enthusiasm.

Most downstream manufacturers are currently purchasing only enough material to cover approximately 7–10 days of consumption, with limited willingness to build inventories. This just-in-time purchasing strategy has kept overall demand relatively stable but has provided little room for significant growth.

Demand from pharmaceutical and disinfectant applications is comparatively stable, but longer procurement cycles and just-in-time purchasing practices make it difficult to generate a substantial increase in short-term consumption.

Electronic-grade isopropanol remains one of the brighter areas of demand. Growth in domestic wafer production and AI-related semiconductor manufacturing continues to support demand from semiconductor, PCB and panel cleaning applications.

However, electronic-grade isopropanol still represents a relatively small portion of total consumption and is therefore unable to fully offset weaker demand for industrial-grade isopropanol during the traditional off-season.

On the export side, overseas inventory accumulation following the June–July export period and the reduced attractiveness of arbitrage opportunities have weakened the ability of export demand to absorb domestic supply.

Overall, demand remains characterized by stable basic consumption but limited growth momentum. With raw material prices already at high levels, downstream buyers have become increasingly price-sensitive, keeping the market firmly in a cost-versus-demand struggle.

IV. Isopropanol Market Outlook: Narrow Fluctuations Likely

Looking ahead, the isopropanol market is expected to remain in a relatively narrow fluctuation range, with strong cost support on the downside and weak demand limiting the upside.

From the cost perspective, if international crude oil prices remain elevated, acetone and propylene are unlikely to experience a sharp decline in the short term. Continued production losses may also encourage producers to maintain firm offers, providing support for the market floor.

From the supply perspective, some previously shut-down facilities are expected to gradually resume operations, which could push industry operating rates higher. Combined with currently adequate spot availability, this may limit further price increases.

From the demand perspective, the traditional September peak season has so far failed to generate the expected recovery. Downstream manufacturers continue to focus mainly on small-volume, just-in-time purchases, providing insufficient momentum for a sustained price rally.

Overall, the isopropanol market is likely to fluctuate at relatively high levels in the short term, with prices remaining close to the cost line.

Further upward movement will likely be constrained by weak downstream demand and limited acceptance of high-priced offers, while significant downward movement may be prevented by high feedstock costs and producers' reluctance to sell below cost.

Therefore, the market may continue to show a “high price, low volume” pattern, with transactions driven primarily by immediate demand.

Going forward, particular attention should be paid to downstream restocking activity, changes in crude oil and feedstock prices, plant operating rates, and new export orders. These factors will be critical in determining whether the current price rally can be sustained or whether the market faces a correction once cost pressure begins to ease.
