BSE introduces pre-open trading for stock futures amid US tariff increases on Indian exports.

The Bombay Stock Exchange (BSE) plans to introduce pre-open trading sessions for stock futures starting December 8, 2025, to enhance trading convenience and strengthen risk monitoring, following regulations by the market regulator Sebi. This move mirrors the existing pre-open sessions in the equity segment, with testing available from October 6. Meanwhile, India's stock market faces selloffs due to additional 25% tariffs imposed by the US, increasing the tax rate on Indian exports to 50%.
