Summary by Relevant Catalogs 3.1 This Week's Synthetic Rubber View - **Supply**: High - cis butadiene rubber production and capacity utilization continued to increase this week. Next week, production is expected to decline slightly due to planned shutdowns and potential restarts [4]. - **Demand**: In terms of rigid demand, the capacity utilization rate of tire sample enterprises is expected to be slightly adjusted. Substitute demand remains high, and overall demand maintains a high year - on - year growth rate [4]. - **Inventory**: As of July 30, 2025, the inventory of high - cis butadiene rubber sample enterprises decreased. Sample production enterprise inventory decreased while sample trading enterprise inventory increased slightly [4]. - **View**: In the short - term, butadiene rubber futures prices are expected to correct from high levels and enter an oscillatory pattern in the medium - term. The theoretical valuation range of butadiene rubber futures is 11,000 - 11,800 yuan/ton [4]. - **Strategy**: For single - side trading, it is bearish. For cross - period trading, there is no recommendation. For cross - variety trading, the NR - BR spread is expected to shrink in the short - term [4]. 3.2 This Week's Butadiene View - **Supply**: Domestic butadiene supply remained stable this week, with production at 103,400 tons and capacity utilization at 69.97% [5]. - **Demand**: The demand from synthetic rubber for butadiene remains high, while the demand from ABS is expected to remain constant, and the demand from SBS maintains rigid procurement [5]. - **Inventory**: The total domestic butadiene sample inventory dropped to a low for the year, with port inventory significantly reduced due to weather - related factors [5]. - **View**: In the short - term, butadiene spot prices are expected to correct, but the decline is limited.
