Assessing the Downward Trajectory in RUBBER-Japan Futures Amid Rising Supply Pressures

The RUBBER-Japan Futures market has entered a period of heightened volatility in 2025, driven by a confluence of supply-side pressures and geopolitical uncertainties.

Supply Pressures and Market Fragility

The monsoon season (July–October) has further complicated the outlook. While above-normal rainfall in Southeast Asia is optimal for latex flow, it also introduces risks of flooding in key producing regions like Thailand's Surat Thani and Trang provincesRubber Rebounds: Japan Futures Find Firm Ground Amid Easing Trade Tensions^[1].

Geopolitical tensions add another layer of uncertainty. The U.S.-China trade war, with tariffs peaking at 145% on Chinese imports by the U.S. and 125% in retaliation, has created a fragile equilibrium. Recent tariff reductions have eased some pressure, but the expiration of the truce in August 2025 could reintroduce volatilityRubber Rebounds: Japan Futures Find Firm Ground Amid Easing Trade Tensions^[1].

Hedging Strategies in a Volatile Landscape

Quantitative Outcomes and Market Behavior

Quantitative assessments of hedging effectiveness highlight mixed results. While the OSE's October 2025 contract closed higher, broader trading volumes have declined as traders adopt a cautious stanceRubber Rebounds: Japan Futures Find Firm Ground Amid Easing Trade Tensions^[1]. This behavior is partly attributed to the yen's stabilization near 145 yen/USD, which supports rubber prices by improving Japanese export competitivenessRubber Rebounds: Japan Futures Find Firm Ground Amid Easing Trade Tensions^[1].
