According to analysts, even though the US bombing of Iran’s three nuclear facilities has worsened the crisis, the impact on the market is likely to be limited. The uncertain factor now is the timing and nature of the Iranian response.

"If Iran targets and damages the US defence facilities in the region or hurts US military personnel seriously, the US response can be huge and this might further worsen the crisis. But the market assessment is that there are limits to what Iran can do against US and Israel," said Dr VK Vijayakumar, Chief Investment Strategist, Geojit Investments Ltd.

The fact is that the closure of Hormuz Strait will harm Iran and Iran’s friend China more than anyone else. The market construct continues to favour a ‘buy on dips’ strategy, he added.

Meanwhile, in the Sensex pack, Infosys, HCL Tech, Hindustan Unilever Limited, Eternal, TCS, Asian Paints, Power Grid, Reliance, ITC were the top losers. Whereas, Bharat Electronics Limited (BEL), Bharti Airtel and Trent were in the list of top gainers.
