Natural Rubber front-month settled at CNY 19,570/t (+0.82%), marking five consecutive green sessions. Joint output curtailment signals from Thailand and Indonesia, plus domestic winter stockpiling by tire makers, are lifting medium-term price floor expectations.

Natural rubber rose 0.64% to CNY 19,535/t—the highest in four weeks—driven by strong auto output: NEV production surged +28.3% YoY in Sep (CAAM), lifting tire plant utilization to 72.5%; butadiene rubber gained 0.43% to CNY 16,475/t.

Natural rubber front-month fell 1.09% to ¥19,470/ton, pressured for two consecutive days; Qingdao port inventories rose 1.8% w/w, and weak replacement-tire demand has dampened procurement intent among major tire makers in Shandong and Jiangsu — sentiment turning cautious.

Butadiene rubber closed at 16,590 yuan/tonne, up 4.54% on the day and outpacing natural rubber's 2.21%. Concentrated maintenance on butadiene units tightened supply; tire exporters settle in dollars, and USD/CNY at 6.7035 thinned the cost increase.
