India’s BSE Sensex fell about 1.7% to close at 73,580.5 on Thursday, its lowest close since June 8, as broad-based selling intensified. Investor sentiment weakened amid crude oil prices above $100 a barrel, rising U.S. Treasury yields, expectations of a Federal Reserve rate hike and persistent geopolitical uncertainty. Financial stocks faced the heaviest pressure after the insurance regulator proposed changes to commissions and distribution payouts, including caps linked to product complexity and measures to spread life insurance commissions beyond the first year. An updated report put the decline at 1.7% and the close at 73,580.5, compared with an earlier report of a 0.9% fall to 74,189 and a lowest level since September 15. Investors also watched the National Stock Exchange’s debut following its 225.6 billion-rupee initial public offering, which was expected to produce a relatively modest 2%-3% gain.
