Rubber prices surge, tire makers announce third round of hikes

The sharp run-up in natural rubber futures, now at multi-year highs, is forcing tire makers to pass on costs through a third round of increases, signaling sustained margin pressure across the downstream sector. The timing—hikes clustered in late August to early September—suggests producers see the cost spike as more than transient, which could amplify inventory-building or restocking decisions along the supply chain. What matters next is whether futures hold these record levels or if supply-side responses, such as increased tapping or release of reserves, emerge to cool the market. The breadth of the rise, from Thai mixed rubber to domestic contracts, points to a globally coordinated cost shock rather than a localized squeeze.
