On Wednesday, October 7, metal and mining shares fell sharply, dragging the Nifty Metal index down 2.3% intraday. The decline followed the Reserve Bank of India’s decision to raise the key repo rate by 25 basis points to 5.5%, a move that shifted the central bank’s stance from ‘neutral’ to ‘calibrated tightening’. Investors reacted to the higher borrowing costs that are particularly painful for capital‑intensive sectors such as metals and mining, which rely heavily on credit for capital expenditure and production expansion.

The Nifty Metal benchmark fell 2.3% to an intraday low of 12,303.45 points, compared with 12,599.75 points at the previous equity market close. By the afternoon session, the index hovered around 12,310 points, down 2.2% from the opening level. The decline was driven by a broad sell‑off across the sector, with several leading names posting significant intraday losses.

National Aluminium, Adani Enterprises, JSW Steel, Hindalco, and Jindal Steel were the top laggards during the session. National Aluminium fell 4.4% to ₹322.25, Adani Enterprises dropped 4.1% to ₹2,732, and JSW Steel slid 2.6% to ₹1,225.90. Hindalco and Jindal Steel both lost 2.5% to ₹916.20 and ₹1,085.90 respectively, while Vedanta Ltd and Vedanta Aluminium fell 2.5% and 1.7% to ₹258.80 and ₹394. Hindustan Zinc and Hindustan Copper posted smaller declines of 1% and 1.4% respectively.

The RBI’s Monetary Policy Committee met on October 7 and confirmed a 25‑basis‑point hike to 5.5%, aligning with market expectations. The central bank highlighted rising inflationary pressures amid global headwinds such as elevated bond yields, higher crude oil prices, and foreign investor outflows. It ruled out imminent rate cuts, stating that the duration and extent of the current tightening cycle would depend on future growth‑inflation developments and outlooks.

Global commodity metal prices also fell during the trading session, further dampening investor sentiment. Aluminium futures slipped 0.80% to around $3,120, marking a 5.7% decline over the past month. Copper futures were down 0.4% on a one‑month basis but rose 0.22% on October 7, while zinc futures fell 0.41% on the day. The volatility in these prices directly impacts the margins of mining companies, forcing them to sell output at lower prices.

The combination of the RBI’s rate hike and the pullback in global metal prices created a negative backdrop for the sector. While banking and financial services stocks gained on the day, metals, auto, and real estate sectors suffered losses due to the anticipated impact of higher borrowing costs. The Nifty Metal index’s 2.3% intraday decline reflects the broader market concern over the cost of capital and commodity price volatility affecting capital‑intensive industries.
