Kottayam (Kerala): International natural rubber prices have scaled historic heights, clearing the ₹300 per kilogram threshold for the first time in history.

In the benchmark Bangkok market, prices peaked at ₹301.25 per kg on June 5, 2026, before climbing further to reach ₹304.62 per kg on June 6. Following a minor correction on Monday, the commodity closed at ₹297.57 per kg.

This unprecedented rally marks a phenomenal 58.78% surge within just six months, up from the ₹191.85 per kg recorded at the start of 2026. The primary catalyst driving this global bull run is a widening mismatch between surging industrial demand and dwindling rubber production.


Global supply shortfalls feed price hike

According to data compiled by the Association of Natural Rubber Producing Countries (ANRPC), global natural rubber output is projected to grow by 2.2% in 2026 to reach 15.32 million tonnes. However, worldwide consumption is set to outpace supply, growing by 1.4% to hit an estimated 15.60 million tonnes, resulting in a distinct market deficit.

Several critical factors have crippled production across Southeast Asian rubber heavyweights, including Thailand, Malaysia and Vietnam.

  • Adverse weather: An abrupt transition from a severe winter straight into unseasonably heavy monsoons drastically reduced the number of viable tapping days across major estates.
  • Geopolitical friction: Escalating conflicts in the Middle East have driven up global crude oil prices. Since synthetic rubber is a petroleum byproduct, its manufacturing cost skyrocketed synchronously.
  • Shift to natural rubber: Faced with prohibitively expensive synthetic alternatives, global tyre manufacturers rapidly pivoted their procurement toward natural rubber, sending demand into overdrive.
  • Logistical hurdles: Global supply chains face severe trade bottlenecks and shipping delays, which have further inflated regional commodity premiums.

Domestic market rallies closer to global levels

Mirroring the international boom, the domestic Indian market has experienced an equally aggressive price surge. The premium RSS-4 grade (Ribbed Smoked Sheet) touched ₹267 per kg in regional markets this week. This represents a solid 48.24% jump from the ₹185 per kg trading price logged at the beginning of 2026.

While these highly lucrative rates are enticing local farmers to aggressively resume tapping operations across idle plantations, persistent heavy rain across key domestic growing regions continues to pose an immediate operational hurdle to harvesting efforts.
