Rubber price today November 19: Increased for 8 consecutive sessions in Japan

World rubber prices continued to rise due to concerns about supply disruptions from Thailand and a weak yen, despite negative signals from China's electric vehicle industry.

Japanese rubber prices increased for 8 consecutive sessions

Rubber futures in Japan rose for an eighth straight session on November 18, boosted by concerns over supply disruptions from Thailand and a weakening yen. However, the market’s gains were capped by weak signs from China’s electric vehicle industry and a drop in global oil prices.

Rubber price developments on international exchanges

Rubber futures prices in the Japanese market continued to rise amid supply concerns.

Key factors affecting the market

Concerns about supply disruptions in Thailand

The main factor supporting rubber prices is weather risks in Thailand, the world’s top rubber producer. The country’s meteorological agency has warned of heavy rains and flash floods from November 17 to 23. This has raised concerns about disruptions to rubber harvesting and transportation, which could push prices higher.

Pressure from electric vehicle industry and oil prices

On the other hand, the market’s upside momentum was limited by weak news from China’s electric vehicle (EV) sector. Electric vehicle maker XPeng forecast lower-than-expected growth in the fourth quarter due to a price war and intensifying competition. The slump in demand for cars could directly impact the output and prices of tires, a product that uses a lot of rubber, putting downward pressure on the price of this raw material.

In addition, the decline in oil prices during the session also negatively impacted the market. Natural rubber has to compete with synthetic rubber, a product made from crude oil, so fluctuations in oil prices often affect rubber prices.

Stable domestic rubber market

In contrast to fluctuations in the world market, domestic raw rubber purchasing prices on November 19 were recorded as stable at major companies.
