Yen Strength and Supply Outlook Drag Japan Rubber Futures Lower

Japanese rubber futures reversed early gains on Tuesday, pressured by a stronger yen and expectations of increased global supply. The benchmark September rubber contract on the Osaka Exchange (TRB1!) closed down 6.5 yen, or 2.23%, settling at 285.3 yen per kilogram ($2.03). The move mirrors pressure across broader commodities tied to industrial activity and global trade sentiment.
The yen’s strength was a key headwind, as the dollar dropped 0.6% to hit a fresh seven-month low against the safe-haven currency. This currency move reduces the attractiveness of yen-denominated assets to overseas buyers and weighs particularly heavily on Japan’s export-linked futures contracts, including rubber. The firmer yen coincides with heightened volatility across global FX markets, driven by U.S. political risk and weakening dollar sentiment.
On the supply side, market participants are beginning to price in an uptick in output. Although rubber crops are still within the traditional low-production window that runs from February to May, harvesting activity is beginning to ramp up in key domestic and overseas regions. According to Chinese data provider Longzhong Information, it may take time for this transition to be fully reflected in inventories, but the broader expectation of higher supply is already pressuring prices.
China’s rubber markets echoed this trend. The September rubber contract on the Shanghai Futures Exchange fell 0.85% to 14,535 yuan per metric ton ($1,988.34), while the May butadiene rubber contract slipped 0.27% to 10,940 yuan ($1,496.56). On the Singapore Exchange, front-month SICOM rubber for May delivery was last quoted at 166 cents per kilogram, down 1.8%.
Meanwhile, persistent Sino-U.S. trade tensions continue to cloud the demand outlook, particularly for rubber end-products such as tires, footwear, and appliances. China has accused the U.S. of tariff abuse and warned other nations against economic alignments that might undercut Chinese interests. Still, the underlying strength in China’s auto sector remains notable—exports hit 1.54 million units in Q1 2025, up 16% year-on-year. This robust growth in auto shipments could support medium-term demand for rubber, depending on how supply dynamics evolve through the upcoming peak production months.
With FX volatility elevated and macro uncertainty clouding both supply and demand forecasts, rubber prices are likely to remain sensitive to currency fluctuations and trade headlines in the near term. Traders should watch closely the progression of harvesting volumes and global auto manufacturing trends, which will be key in shaping the next leg for rubber markets.
