The Indian equity markets opened on a positive note on Monday, driven by gains in realty stocks and correction in crude prices.

Despite escalation of conflicts in the Middle East and the Russia-Ukraine war, Brent crude declined to below $102 due to the increasing oil flow through the Strait of Hormuz.

"The US 10-year bond yields are hovering around 5 per cent posing a threat to equity markets. But equity markets are holding their ground taking cues from the robust growth in developed economies and expectations of good corporate earnings. In India, too, this pattern is playing out," an analyst said.

Global markets remain mixed, with Asian equities gaining on technology strength while easing crude prices are offering some relief.
