橡胶价格下跌，轮胎涨价潮结束

橡胶价格下跌：多重利空因素叠加施压

9月23日，天然橡胶价格跌破15000元/吨，较今年年初高点17855元明显回落。核心驱动因素是供应端预期逆转以及政策信号的变化。

从供应端来看，市场对季节性增产的预期已成为看跌押注的核心依据。市场普遍预计，东南亚和中国的主产区将从即日起至10月进入传统的乳胶生产旺季。云南地区的供应已逐步增加，尽管海南受台风影响有所干扰，但整体供应上升趋势明确。

更重要的是，国储胶意外抛售——此前市场普遍认为国储没有全乳胶库存。实际抛售计划对浅色胶价格产生直接利空影响，使得抛储量成为影响短期价格的关键变量。此外，中泰湄公河橡胶出口试点项目即将启动，零关税政策可能进一步缓解远期供应压力，加剧市场看跌情绪。

More importantly, the unexpected sales of state reserves – previously, the market generally believed that state reserves had no full latex inventory. The actual sales plan had a direct negative impact on light-colored rubber prices, making the sales volume a key variable influencing short-term prices. Furthermore, the China-Thailand Mekong River rubber export pilot program is about to launch, and the zero-tariff policy may further ease forward supply, exacerbating market bearish sentiment.

需求疲软加剧了价格下行压力。尽管山东全钢轮胎产能利用率已上升至近期高点64.87%，但终端用户的需求消化缓慢。下游企业对高价原材料接受度较低，采购仅限于刚性需求，观望情绪明显。

海外市场也面临压力。尽管美国加征关税并未抑制进口，但支撑订单增长的动力不足，且欧盟需求略有下降，难以对需求形成托底作用。

宏观经济支撑也有所减弱。尽管目前处于预防性降息周期，历史数据显示这很可能在中期内对橡胶价格产生积极影响。然而，美联储最新的点阵图显示降息步伐将放缓，这令市场对宏观环境的乐观情绪降温，并降低了投资者对橡胶等风险资产的兴趣。

价格上涨消退：轮胎企业面临成本压力缓解。

橡胶价格的下跌直接终结了今年轮胎价格的第二轮上涨，与年初的涨价逻辑形成鲜明对比。

从年初到三月的第一波涨价，主要受天然橡胶价格同比上涨33.89%以及炭黑等原材料价格上涨推动。这使得单条12R22.5轮胎的原材料成本增加了约55元，迫使米其林、玲珑等国内外企业集体提价3%至10%。

第二波价格上涨始于7月和8月，最初由供需紧张信号推动，包括泰国产量未能如期增加以及国内库存下降至123.5万吨。然而，随着橡胶价格跌破成本支撑位，价格上涨的基础已不复存在。

目前，轮胎企业面临的成本压力明显减轻。天然橡胶约占轮胎生产成本的40%，价格每下降1000元/吨，单条轮胎成本可降低约20至30元。

随着合成橡胶开工率恢复至75%以上，供应充足进一步降低了替代成本，完全消除了涨价动力。从市场反应来看，自8月以来没有大型企业宣布提价，部分中小型经销商甚至开始降价以规避风险。

市场展望：波动市场中的多空博弈

短期内，天然橡胶市场将维持高位承压、低位支撑的震荡格局。利空方面，10月处于供应释放的高产期，后期黑胶库存预期增加以及收储落地等因素将继续压制价格。但同时，也存在一些支撑因素。

The second wave of price increases, brewing in July and August, was initially driven by tight supply and demand signals, including Thailand's production failing to increase as it should have and domestic inventories falling to 1.235 million tons. However, with rubber prices falling below cost support, the basis for price increases has disappeared.

Currently, tire companies are facing significantly less cost pressure. Natural rubber accounts for approximately 40% of tire production costs, and every 1,000 yuan/ton drop in price reduces the cost of a single tire by approximately 20-30 yuan.

Coupled with the recovery of synthetic rubber operating rates to over 75%, ample supply has further reduced substitution costs, completely fading the motivation for price increases. Judging from the market reaction, no major companies have announced price increases since August, and some small and medium-sized distributors have even begun offering discounts to mitigate risks.

Market Outlook: A Bull-Bear Game in a Volatile Market

In the short term, the natural rubber market will remain volatile, with pressure from above and support from below. On the negative side, factors such as the release of supply during the peak production period in October, the expected increase in dark rubber inventory, and the realization of stockpiling will continue to suppress prices. However, supporting factors also exist.

泰国东北部降雨及海南台风可能影响实际生产，泰铢升值将增加进口成本，123.5万吨的社会库存仍处于相对低位。

对于

For the 轮胎市场方面，成本下降有望改善企业利润。此前，由于原材料价格上涨，贵州轮胎等企业毛利率同比下滑7.24个百分点。若橡胶价格持续处于低位，行业盈利能力有望逐步恢复。然而，需求端的不确定性仍是值得关注的问题。

“金九银十”旺季表现或不及预期，新能源汽车购置税免征政策退坡可能提前透支四季度需求，这些因素将制约轮胎企业盈利修复空间。

从长期来看，橡胶生产周期转变导致的供应上限，以及终端新能源汽车渗透率提升带来的需求增长，仍将是决定市场走势的核心矛盾。投资者应重点关注10月实际产量数据、收储落实情况及汽车产销数据，以在波动市场中识别趋势性转折。

In the long term, the supply ceiling caused by the shift in the rubber production cycle and the increase in demand driven by the increasing penetration of new energy vehicles at the end-user end will remain the core contradictions determining market trends. Investors should focus on October's actual production data, the implementation of stockpiling, and automobile production and sales data to identify trend reversals within the volatile market.
