Synthetic Rubber Cost Pressures Lift Natural Rubber Prices Across South India

South India’s rubber landscape is feeling the ripple effect of rising synthetic‑rubber costs. In Kanyakumari district, after a blistering September heatwave cut latex output by roughly thirty per cent, dealer prices have climbed, echoing a national trend.

The shortage of raw latex in both Kanyakumari and neighboring Kerala has tightened supplies, while industrial demand—particularly from tyre manufacturers—keeps the market buoyant. Traders note that the persistent industrial order book is a key factor sustaining price levels.

On Tuesday, the Kottayam market listed dealer rates of Rs 271 per kilogram for RSS‑4 and Rs 266 for RSS‑5, with ISS grade at Rs 256. The Rubber Board’s quoted figures were higher, at Rs 279 for RSS‑4 and Rs 274 for RSS‑5, and it priced 80 % processed latex at Rs 191 per kilogram.

Farmers have welcomed the price boost, yet they stress that earnings depend heavily on the quantity they can harvest. A brief spell of light rain in the district’s hilly terrain has produced a small uptick in latex flow, but production remains below normal levels.

The synthetic‑rubber surge stemmed from a disruption in crude‑oil supply caused by geopolitical friction between the United States and Iran earlier this year. Since synthetic rubber is derived from petroleum, the spike in oil prices translated into higher synthetic‑rubber costs, which in turn lifted natural‑rubber valuations. Even after crude imports steadied, the natural‑rubber market has not retreated.

Rising demand from the automotive sector, paired with domestic output that fails to meet consumption, keeps the price environment tight. Growers are now dependent on forthcoming rains to boost latex production and ease the current mismatch between supply and demand.
