Lead: Early in the week, US-Iran talks hit a deadlock, reigniting geopolitical risks in the Middle East, and rising international oil prices lifted sentiment in the chemical market. Driven by higher cost expectations, DOTP prices rebounded against a broadly bearish market mood, and industry profit margins recovered modestly, returning to profitability.
I. DOTP Market Holds Firm amid Stalemate
On Tuesday, geopolitical tensions suddenly flared up again, and international crude oil prices rose in response, significantly boosting market sentiment. DOTP traders’ confidence recovered accordingly, and offers moved higher. Driven by “buy-on-strength” sentiment, some downstream users made opportunistic restocking at lower prices, and transactions in low-price regions picked up somewhat, further encouraging sellers to firm up quotations. Taking Zhejiang as an example, as of Thursday, the mainstream ex-works price in the DOTP market stood at around 8,850 yuan/mt, up 200 yuan/mt from last Thursday, an increase of about 2.31%. The weekly average price was 8,800 yuan/mt, up 150 yuan/mt from the previous week’s average, an increase of 1.73%.
The latest rise was mainly driven by external macro positives, quickly shifting market expectations from bearish to bullish. Cost support, combined with staged restocking demand, pushed prices higher in the short term. However, end-user demand has not improved substantially. Downstream buyers mostly restocked only for short-term rigid needs, purchasing momentum remained weak, and acceptance of high-priced materials was low, with cautious sentiment toward chasing gains. As a result, trading cooled again in the latter half of the week, and the market returned to a wait-and-see stalemate. Traders operated more conservatively, keeping quotations in a narrow range.
II. DOTP Profit Margins Improve Slightly
Driven by the early-week speculative rally, DOTP spot price gains outpaced feedstock cost increases, leading to a marked recovery in industry profitability. The sector emerged from its previous loss-making position and returned to profit. Taking Zhejiang as an example, as of Thursday, the theoretical profit for DOTP producers was about 18 yuan/mt, up 66 yuan/mt from last Thursday. The weekly average theoretical profit for the industry was also 18 yuan/mt, up 39 yuan/mt from the previous week’s average, an increase of about 185.71%, reflecting improved profitability. However, this profit recovery was largely sentiment-driven, lacking sustained positive support, which limited the upside room and sustainability of DOTP price increases. Producers’ shipments were mostly supported by earlier low-priced orders, while uptake of high-priced new orders was weak and follow-through transactions were sluggish. With cost-side support pitted against soft demand, it remains difficult for DOTP producers to further expand profit margins.
III. DOTP Operating Rates Rise
From late last week to early this week, a combination of tight upstream octanol supply and temporary maintenance at some domestic DOTP units caused the overall DOTP operating rate to decline noticeably, with domestic capacity utilization once falling to a low of 54%. Spot supply was temporarily tight. Even though new-order transactions were limited overall, producer inventories did not accumulate significantly; some plants even had queues for deliveries. This effectively supported producers’ price-holding and hike-seeking mentality early in the week, providing supply-side support for the market rebound.
As upstream octanol units gradually resumed production this week, the tight feedstock supply situation eased. Shandong Jianlan’s octanol unit returned to full operation, and Anqing Shuguang’s unit restarted smoothly after a brief shutdown. Domestic octanol supply increased by 4,200 mt from last week, and the industry operating rate recovered to 68%, up 5 percentage points week-on-week. The ample return of feedstock supplies laid a solid foundation for higher DOTP operating rates. At present, domestic DOTP capacity utilization has recovered to 62%, a moderate operating level for the year. As industry operating rates steadily recover, the earlier tight spot delivery situation is expected to gradually ease, and supply-side constraints will continue to weaken going forward.
IV. Market Outlook
On the cost side, negotiations at high prices in the core feedstock octanol market are gradually reaching a stalemate, and spot supply remains generally tight. Octanol prices are expected to mainly consolidate at high levels next week. For the co-feedstock PTA, the short-term tight supply-demand pattern is unlikely to reverse, spot market liquidity is insufficient, and prices will maintain a firm tone. Overall, DOTP’s cost side retains bottom-line support, but the upward momentum of feedstocks has slowed, providing limited impetus to spot prices.
On the supply-demand side, there has been no substantial recovery in end-user markets. Downstream buyers mostly maintained a pattern of periodic rigid-demand restocking. Market transactions were scattered and lacked continuity, with weak acceptance of high-priced materials. That said, some DOTP plants still have delivery queues at present, and overall producer inventories remain low, with no obvious accumulation pressure, providing a certain degree of bottom support for the market.
In a comprehensive analysis, the current DOTP market is characterized by a clear long-short tug-of-war: weak end-user demand caps the upside room for prices, and high-priced materials face the risk of pulling back under pressure. Meanwhile, a relatively strong cost floor and low producer inventories limit the downside, and producers are generally cautious about offering price concessions. It is expected that the DOTP market will mainly fluctuate within a narrow range next week. Going forward, close attention should be paid to geopolitical developments in the Strait, and market participants should be wary of rapid swings in international crude oil sentiment that could shift feedstock and DOTP spot prices in the near term.
