Indian equities are seeing intraday declines and rebounds, with the Sensex dropping by roughly 400–440 points in one session as crude prices rise on intensifying US-Iran concerns. Multiple live updates report the market’s direction is closely linked to moves in Brent and WTI, which fluctuate sharply during the day.

The context across reports centers on supply-risk expectations tied to the Strait of Hormuz and US-Iran developments. Some updates describe a “Hormuz deadlock,” keeping traders cautious and supporting higher oil prices, while others cite reports of talks or a ceasefire/peace efforts that ease supply fears and pull oil lower. Correspondingly, Brent trades around levels reported as above $90 or near mid-$80s in different reports, and WTI likewise swings around the $80–$91 range. Global cues are described as mixed, with Asian markets noted as mixed in at least one update.

Overall, outlets consistently connect Sensex and Nifty performance to oil-price volatility driven by the US-Iran situation and uncertainty over Hormuz reopening, while differing in the specific point moves and the day’s direction depending on the timing of updates and the latest oil headline.
