Shares of Indian aluminium producers came under pressure on June 16, with Hindalco Industries, National Aluminium Company (NALCO), and Vedanta declining by as much as 5 percent during trade as global aluminium prices weakened significantly. The selloff followed the announcement of a preliminary peace agreement between the United States and Iran, which reduced concerns about supply disruptions that had previously supported aluminium prices.

Aluminium prices fell to their lowest level in more than two months as markets reassessed the supply outlook. The easing of geopolitical tensions raised expectations that trade routes and industrial supply chains in the Gulf region could normalize, reducing the risk premium embedded in aluminium prices.

During the earlier phase of the Middle East conflict, aluminium prices had surged to multi-year highs due to concerns over production disruptions and logistics bottlenecks affecting global supply. The resulting rally had boosted investor sentiment toward aluminium producers such as Hindalco, NALCO, and Vedanta, whose earnings are closely linked to international metal prices.

However, with prospects of improved supply conditions following the US-Iran agreement, analysts have turned more cautious on the metal. Bank of America analysts indicated that aluminium prices appear vulnerable in the near term as supply risks recede while concerns over demand remain. The changing outlook triggered profit booking across metal stocks, leading to weakness in the Nifty Metal index.

The decline highlights the sensitivity of aluminium producers to global commodity price movements and geopolitical developments. Investors will continue to monitor the sustainability of the peace agreement and its impact on global metal markets in the coming weeks.
