Introduction: With weak downstream demand support, cost transmission in the DOTP market has encountered obstacles. Prices spiked and then pulled back, and profit margins have been gradually compressed. Taking Zhejiang as the sample region, the theoretical profit of DOTP enterprises on Thursday this week was 27 yuan/ton, down 238 yuan/ton from last Thursday, a decline of approximately 90.83%.
I. Limited spot supply of feedstock octanol slows the pace of price declines
This week, the weekly capacity utilization rate of feedstock octanol fell for the fifth consecutive week. The average weekly utilization rate was 62%, down 17 percentage points from 79% at the beginning of the month, while weekly output declined by 21.99%. Although the operating rates of the major downstream products DOP and DOTP also declined this week, the declines were far smaller than the reduction in octanol supply. During the week, Shandong Jianlan's octanol unit failed to resume operations as scheduled, and octanol units in East China continued to operate at medium loads. With spot supply tight, market prices were supported in a high-level, narrow consolidation, and the pace of price declines remained slow. As of Thursday, the octanol market price in Shandong stood at 7,850 yuan/ton, up 250 yuan/ton from last Thursday.
II. Recurring geopolitical tensions trigger wide fluctuations in feedstock PTA prices
PTA, the other feedstock for DOTP, was priced at 5,895 yuan/ton on Thursday, down 195 yuan/ton from last Thursday. Although prices declined, market sentiment was frequently affected by geopolitical developments in the Middle East during the week, resulting in wide price swings. Escalation and de-escalation expectations for the Middle East conflict alternated, driving repeated ups and downs in the geopolitical risk premium on crude oil. During periods of heightened tension, rising risks to strait transit pushed oil prices up, providing cost support for PTA. When de-escalation expectations strengthened, the geopolitical premium quickly dissipated and cost-side support weakened. The frequent shifts in news headlines triggered rapid changes in market expectations. Geopolitical sentiment and crude oil costs became the dominant logic driving the market, with long and short forces locked in a tug-of-war, keeping PTA prices fluctuating widely.
III. Poor new order activity compresses DOTP profit margins
As of now, the mainstream ex-factory price of DOTP in Zhejiang is 8,700 yuan/ton, up 1,000 yuan/ton from the low point at the beginning of the month. Downstream acceptance of the current price is clearly limited. Cost-side support has been unable to effectively offset the negative impact of weak demand. In the ongoing contest between cost and demand, the profit space of DOTP enterprises has been continuously squeezed.
From a profitability comparison across the industrial chain, feedstock octanol performed the best. Supported by tight spot supply, octanol prices declined only slowly. This week, the average weekly profit for octanol was 474 yuan/ton, up 811 yuan/ton from the previous week, turning from loss to profit and forming a sharp contrast with the profitability of downstream products.
The sustained tug-of-war between cost and demand has gradually narrowed DOTP profitability. Weekly data show that the average weekly theoretical profit for DOTP in Zhejiang fell to 189 yuan/ton this week, down 20 yuan/ton from last week, a week-on-week decline of 9.57%. As of Thursday this week, the theoretical profit for local enterprises stood at only 27 yuan/ton, down 238 yuan/ton from last Thursday, a decline of as much as 90.83%.
Overall downstream demand remained weak, and buying sentiment in the market was cautious. Faced with high raw material costs, downstream enterprises only maintained purchases based on rigid demand, with no concentrated restocking. As a result, the DOTP market could not establish sustained transactional support. Market participants held a relatively pessimistic outlook, merchants faced pressure in moving goods, and price concessions to stimulate sales became more common, further squeezing the industry's profit margins.
IV. Market Outlook
Bullish and bearish factors are intertwined on the cost side. For the key feedstock octanol, supply in the Shandong region is expected to recover at certain stages, increasing spot shipment pressure and putting near-term prices under pressure. However, supply in East China remains tight, and with some Shandong units planned to enter maintenance in mid-August, medium- to long-term bottom support for octanol prices will remain in place. The other feedstock, PTA, continues to fluctuate with crude oil costs. Its market is mainly driven by geopolitical sentiment, and with no sustained positive fundamentals, upside potential is limited. Overall, short-term cost support for DOTP has weakened somewhat, but medium- to long-term bottom support still exists.
On the supply-demand side, downstream demand has yet to see substantial improvement. End users have limited acceptance of the current high DOTP prices, and the weak trading pattern is difficult to reverse. Even if market sentiment triggers periodic restocking, it will not provide sustained demand support.
In comprehensive analysis, DOTP demand is currently weak and prices are under pressure. However, medium- to long-term cost-side bottom support will limit the downside space for DOTP prices. Going forward, market players should continue to monitor geopolitical developments around the strait and remain alert to market fluctuations caused by rapid shifts in crude oil sentiment.
