U.S.-Iran Strait Deal Cuts Oil, Lifts Indian Benchmarks

Indian equity benchmarks opened higher on Tuesday after a weekend U.S.-Iran agreement to reopen the Strait of Hormuz sent Brent crude lower and reignited global risk appetite. The 30-share BSE Sensex rose 272.87 points to 76,537.20, while the Nifty added 69.15 points to 23,921.55.

Brent crude slipped 0.32% to $82.90 a barrel. Sunday's deal between the U.S. and Iran, brokered by Pakistan, would restore oil and natural gas flows through the Strait, a chokepoint for roughly a quarter of global seaborne crude. The drop in oil prices is a direct tailwind for India, which imports about 85% of its crude requirements. Rajesh Palviya, Head of Research at Axis Direct, said the decline in Brent is a "key positive for Indian equities" alongside sustained domestic institutional buying.

The rally carried through from Monday, when the Sensex jumped 736.38 points and the Nifty surged 231 points. Foreign institutional investors turned net buyers that day, purchasing equities worth Rs 200.05 crore, exchange data showed. Overnight, the Nasdaq Composite jumped 3.07% and the S&P 500 surged 1.65% to fresh records.

Yet the deal's fine print remains missing. No details of the agreement have been made public. Iran has said implementation will begin only after a formal signing ceremony. Pakistan, the mediator, confirmed that ceremony is scheduled for Friday in Switzerland. That gap between Sunday's handshake and Friday's signing creates a week of execution risk. If the ceremony proceeds smoothly, Brent could drift toward $80 or lower, reinforcing the oil tailwind for Indian markets. If it stalls or the terms prove narrow, the risk premium could snap back.

Among the biggest early winners on the Sensex were HCL Tech, Bajaj Finance, Bajaj Finserv, Hindustan Unilever, Tech Mahindra, and Tata Consultancy Services. Axis Bank, Tata Steel, Power Grid, and UltraTech Cement lagged. In Asia, South Korea's Kospi and Japan's Nikkei 225 traded higher, while Hong Kong's Hang Seng slipped.

Friday's signing is the next concrete marker. Until the terms are known, traders are pricing relief without clarity on duration or scope.
