合成橡胶期货价格大涨 天然橡胶价格为何温吞震荡？

Core Insights - The domestic futures market for rubber shows a clear divergence, with synthetic rubber futures rising nearly 4%, while natural rubber and No. 20 rubber futures exhibit a more moderate performance, attributed to multiple factors including cost dynamics, supply changes, and seasonal demand [2] Group 1: Synthetic Rubber Market - The significant rise in synthetic rubber futures is primarily driven by cost factors, particularly the decrease in port inventory of the raw material butadiene, leading to tighter supply and enhanced cost support [2] - The relationship between synthetic rubber and natural rubber is strong, with supply contraction in natural rubber due to stoppages in Yunnan and an expanded price gap between Thai mixed rubber and synthetic rubber providing additional support for synthetic rubber prices [2] - Despite the recent price rebound, the weak downstream demand poses a challenge for the sustainability of synthetic rubber price increases, particularly during the seasonal demand lull in the tire market [2][3] Group 2: Tire Industry Impact - The tire industry, a major consumer of synthetic rubber, is expected to underperform in Q4, with a significant year-on-year decline in capacity utilization for semi-steel tire manufacturers, indicating a slowdown in synthetic rubber demand [3] Group 3: Supply Dynamics - Although the trading atmosphere for synthetic rubber has improved, inventory levels remain high and supply is ample, with the price of butadiene lacking sustained upward momentum, suggesting that the recent rebound is more of a correction from overselling rather than a strong upward trend [4] - For natural rubber, the focus is on supply, with recent rainfall in Thailand affecting rubber tapping, but the increase in exports from Thailand has alleviated concerns about supply shortages, maintaining a neutral supply-demand structure [4] Group 4: Future Outlook - The short-term outlook for synthetic rubber prices is expected to maintain a phase of recovery due to improved macroeconomic conditions, while natural rubber and No. 20 rubber prices may remain relatively weak due to seasonal demand factors [4] - The potential for further price increases in synthetic rubber futures appears limited, with expectations of a bottoming and oscillating pattern [5]
