Sensex, Nifty jump 1% as Brent slips below $100

Market opens stronger on lower crude

Indian benchmark indices Sensex and Nifty opened higher in Mumbai, tracking a sharp correction in crude oil prices and a firmer tone across global markets. The move came as investor sentiment improved on reports and commentary pointing to progress in US-Iran negotiations. Lower oil prices were a key support for domestic equities, given India’s dependence on imported crude. Market participants also cited a risk-on mood globally, aided by gains in Asian equities.

US-Iran negotiation headlines set the tone

The immediate trigger for the early rally was optimism that the United States and Iran could be nearing an understanding that reduces disruption risks in the Persian Gulf. One report said global markets cheered talks linked to reopening shipping routes, including the Strait of Hormuz, after war-related disruptions. President Donald Trump was also cited saying the Strait of Hormuz could reopen to all if Iran accepts a US agreement. The same set of reports noted oil prices briefly dipped below $17 before rebounding above $100, reflecting the sensitivity of energy markets to geopolitical signals.

What Indian market strategists said

V K Vijayakumar, Chief Investment Strategist at Geojit Investments Ltd, said markets began the week on a positive note as crude dipped by about USD 5 to below USD 100 on expectations that the US and Iran were close to a deal. He added that the market would “wait and watch” for clarity and certainty, noting that similar expectations had been disappointed since the start of the war. He also said a sustained drift down in crude, if the expected deal holds, could become a turning point for the market.

Strong Wednesday close: best single-day gain in nearly three weeks

Beyond early trade moves, Indian equities also saw a sharp late surge on Wednesday, described as the strongest single-day gain in nearly three weeks. The rally followed reports of a possible US-Iran accord that was linked to an 8 percent plunge in oil prices. The NSE Nifty 50 gained 1.2 percent, or 298.15 points, to close at 24,330.95. The S&P BSE Sensex rose 1.2 percent, or 940.73 points, to end at 77,958.52.

Early trade snapshot: May 6 rebound

In another early session update dated May 6 (PTI), Sensex and Nifty rebounded in early trade after crude prices eased following Trump’s claim of progress in negotiations with Iran toward an agreement to end the war. In that report, the 30-share BSE Sensex jumped 657.22 points to 77,675.01 in early trade, while the 50-share NSE Nifty rallied 218 points to 24,250.85. Brent crude, the global oil benchmark, was cited trading 1.67 percent lower at USD 108 per barrel at that time.

Global cues: Asia trades higher

Asian equity cues were supportive in the earlier session described in Mumbai. Japan’s Nikkei 225 index and China’s Shanghai SSE Composite index were both reported trading higher. The combination of firmer global equities and easing crude strengthened the domestic risk appetite.

Oil’s swing: from above $115 to near $100

Multiple updates in the provided text highlighted large intraday moves in Brent crude. One report said Brent fell 7.8 percent to $101.27 per barrel from over $115 earlier in the week. Another said Brent plunged 10.6 percent to $18.20 per barrel, described as its lowest in two weeks. A separate market wrap cited Brent crude futures dropping to around $100.7 a barrel, after holding above $100 for nearly two weeks. The common thread across these updates was that negotiation-related headlines drove rapid repricing of supply risk.

Key data points at a glance

Market impact: why crude matters for Indian equities

The session underscored how quickly Indian equities react to crude oil swings, especially during geopolitical uncertainty. A drop in crude can ease pressure on inflation expectations and improve sentiment in an import-dependent economy, which was explicitly noted in the provided text. The rally was also described as broad-based, supported by expectations that talks outweighed near-term supply disruption fears. Vinod Nair, Head of Research at Geojit Investments Limited, said optimism around potential US-Iran negotiations supported sentiment and drove oil prices below $100, as per the report.

Analysis: relief rally, but traders watch for confirmation

The price action showed a classic relief rally dynamic: lower crude, improved global cues, and reduced immediate tail-risk pricing lifted equities. At the same time, strategists highlighted the need for clarity because earlier expectations around the conflict had been belied. With oil and equities reacting to headlines, investors are likely to monitor further official updates on negotiations and shipping conditions in the Gulf.

Conclusion

Sensex and Nifty advanced as crude corrected sharply and global markets strengthened on improving sentiment around US-Iran negotiations. The next market cues will depend on whether negotiation signals translate into clearer, verifiable steps that keep oil prices contained and reduce supply risk concerns.
