Report Summary 1. Investment Rating - No investment rating is provided in the report. 2. Core View - The cost recently supports the offer price of butadiene rubber, but the supply will increase after the restart of maintenance devices. The negotiation focus of spot - end traders and downstream is divergent. The inventory of butadiene rubber sample enterprises increased slightly last week. Although some production devices were shut down for short - term maintenance, the price center of the spot end is low due to the downstream's wait - and - see sentiment and arbitrage resources. This week, with the co - existence of device maintenance and restart, the supply is expected to change little. Under the shipping pressure, the inventory of production enterprises is expected to decline slightly, while the inventory of trading enterprises is expected to increase. In terms of demand, the capacity utilization rate of domestic tire enterprises fluctuated slightly last week. The production capacity utilization rate of domestic tire enterprises may be slightly adjusted in the short term, with limited overall fluctuation space. The BR2509 contract is expected to fluctuate in the range of 11,680 - 12,200 [2]. 3.

The main contract for synthetic rubber BR2509 closed at 11,785 yuan/ton, an increase of 2.48% compared to the previous day's settlement price. On the cost side, the Maoming Petrochemical butadiene unit is restarting, and Fushun Petrochemical plans maintenance, while Jilin Petrochemical is in the commissioning phase, indicating a potentially ample domestic supply. Additionally, port inventories remain relatively low, with expected concentrated imports arriving in late August, limiting the downside for butadiene in the short term. Supply-side dynamics show a mix of unit restarts and maintenance, with a slight expected increase in styrene-butadiene rubber supply and limited inventory depletion. Demand-side pressures persist, particularly for semi-steel tires, which maintain high inventory levels, complicating production rate increases. Overall, while the cost side has limited downside, the supply-demand balance for BR remains loose, suggesting a wide fluctuation in prices [5]

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - This week, the domestic cis - butadiene rubber spot price showed a weak consolidation. The ex - factory price of high - cis butadiene rubber of Sinopec Chemical Marketing decreased by 100 yuan/ton in total, and that of PetroChina's sales companies decreased by 300 yuan/ton in total. As of July 10, 2025, the mainstream ex - factory price of high - cis butadiene rubber in China was 11,400 - 11,600 yuan/ton [7]. - Recently, the low - price transactions at the raw material butadiene end have gradually improved. Affected by the news of a fault in an upstream device in East China, some rigid - demand purchases have followed up with price pressure. The overall inventory of butadiene rubber production enterprises has increased slightly, while the inventory of trading enterprises has decreased slightly. The cost factor supports the current butadiene rubber price, but downstream purchases remain cautious, and the resistance to shipment may increase. It is expected that the short - term inventory level may increase slightly [7]. - This week, the capacity utilization rates of domestic tire enterprises varied. The production schedule of semi - steel tire enterprises under maintenance at the beginning of the month gradually recovered, which boosted the overall capacity utilization rate of tire enterprises this week. An individual all - steel tire enterprise was under maintenance, dragging down the capacity utilization rate of all - steel tires slightly. Next week, the production schedule of the maintenance enterprises will return to the normal level, and the capacity utilization rate still has room for recovery, which will boost the overall capacity utilization rate of tire enterprises [7]. - The short - term forecast for the br2509 contract is to fluctuate in the range of 11,200 - 11,700 [7]. 3.
