Crude Drop Fuels Sensex Rebound as Oil, Bank Stocks Lead

Brent crude fell 1.7% on Monday, settling at $79.23 a barrel, after the U.S. and Iran agreed on a 60-day roadmap toward a final nuclear deal. The BSE Sensex rose 291 points, or 0.38%, to 77,094.07, recovering roughly half of Friday's 607-point drop. The Nifty gained 89.80 points to 24,102.90.

Oil and gas, banking, and pharma stocks drove the move. Reliance Industries added 1.31%, HDFC Bank firmed, and Infosys rose 1.29%. The BSE Utilities sub-index jumped 1%, while Healthcare and Energy each rose about 0.7%. Consumer durables posted the worst sector performance, down 1.05%, dragged by Asian Paints (down 2.15%) and Titan (down 1.11%).

Foreign institutional investors bought equities worth ₹4,859 crore on Friday, exchange data showed. That followed a stretch of heavy selling in early June. Analysts tied the rebound directly to the crude slide and the diplomatic breakthrough.

Ponmudi R, CEO of Enrich Money, said global sentiment strengthened after the first round of U.S.-Iran negotiations ended on a constructive note. The continuation of technical talks through the week has reinforced hopes of further diplomatic progress, he added.

Vinod Nair, head of research at Geojit Investments, described the session as constrained to a narrow range but with a positive bias. He flagged outperformance in utilities, banking, and healthcare as investors assessed the talks' progress.

The U.S. and Iran issued a joint statement through mediators Pakistan and Qatar on Monday, confirming a two-day meeting in the Swiss resort of Burgenstock had produced a framework for a final agreement. Technical teams are scheduled to continue discussions this week, with the next formal round expected within 60 days.

A lower crude price directly benefits India’s import-dependent economy. Every $10 drop in the oil price cuts roughly $15-20 billion from the annual import bill, improving the current account deficit and supporting the rupee. It also reduces the subsidy burden on fertilisers and cooking gas, giving the government more fiscal space. For oil marketing companies, cheaper feedstock boosts refining margins and lowers working capital needs.

Asian markets were mixed. South Korea's Kospi and Japan's Nikkei 225 closed higher; Hong Kong's Hang Seng slipped. European markets traded lower in afternoon trade.

On the BSE, 2,635 stocks advanced, 1,754 declined, and 197 were unchanged. The SmallCap Select index rose 0.6%, and the MidCap Select index gained 0.45%.
