Isooctanol experienced volatile downward movement in April
According to the SunSirs Commodity Market Analysis System, the price of isooctanol stood at 8,933.33 RMB/ton on April 27. This represents a fluctuating decline of 3.60% compared to the price of 9,233.33 RMB/ton at the beginning of the month; however, relative to the price of 6,700 RMB/ton at the start of March, the cumulative increase remains substantial at 36.32%, placing the market within a "warning zone" for excessive price growth over a one-year period. Throughout April, the isooctanol market exhibited an overall pattern characterized by "high-level volatility—strong performance initially, followed by weakness." At the beginning of the month, the market extended the strong upward momentum seen in March, surging to a new annual peak; subsequently, influenced by declining production costs and a supply-demand standoff, prices underwent a gradual correction. For the entire month, prices fluctuated within the 9,000–9,500 RMB/ton range, maintaining an overall position at a high level for the year. Market dynamics were primarily driven by the interplay with crude oil and propylene markets, as well as shifts in the supply-demand landscape; furthermore, starting from mid-April, the moving average of prices tracked by SunSirs began to trend downward, signaling a distinct downward trajectory in the isooctanol market.
Cost Side: Crude oil and propylene moved in tandem, providing support that was initially strong but subsequently weakened
According to the SunSirs' Commodity Market Analysis System, during the period of April 1–7: Propylene futures prices traded at elevated levels. On April 7, the closing price for the main propylene futures contract reached 9,447 RMB/ton. This trend was reinforced by earlier crude oil prices—which were bolstered by geopolitical factors—providing strong cost-side support for isooctanol and driving its prices upward. However, following the entry into force of the ceasefire agreement between the U.S. and Iran, crude oil prices plummeted; propylene prices underwent a synchronous correction, with the closing price of the main propylene futures contract falling to 8,360 RMB/ton on April 27—a decline of 11.51% compared to April 7. Consequently, cost-side support for isooctanol weakened, placing downward pressure on its prices and triggering a correction; furthermore, the price ratio index between propylene and isooctanol remained at a high level, further intensifying the downward pressure on isooctanol prices.
Isooctanol Market: Weakness on Both Supply and Demand Fronts
In April, operating rates among isooctanol producers remained at elevated levels; however, the operating loads of individual production units subsequently declined, causing the overall operating rate to drop to approximately 80% by month-end, resulting in a reduction in isooctanol supply. Downstream purchasing was driven primarily by immediate, essential needs. Concurrently, operating rates within the plasticizer sector declined in April; specifically, the operating load for DOP fell from 66% in March to 55% in April. This downturn in production activity reduced the plasticizer industry's demand for isooctanol, thereby dampening the upward momentum of isooctanol prices. Consequently, market conditions for isooctanol were characterized by weakness on both the supply and demand fronts.
Market outlook
According to analysts at SunSirs, isooctanol product data analysis, on the cost side, crude oil prices are unlikely to rebound significantly due to the US-Iran ceasefire, and propylene prices are likely to remain volatile, further weakening cost support for isooctanol. On the supply and demand side, both isooctanol and plasticizer plant operating rates have declined, resulting in weak supply and demand, making it difficult to support price increases. In summary, with declining costs and weak supply and demand, isooctanol prices are expected to fluctuate slightly downwards in the near future.
