Indian equities experienced their sharpest single-day sell-off in ten weeks on Thursday, with the Nifty 50 index closing down 1.6% at 23,063.10 points and the BSE Sensex index falling 1.67% to 73,580.54 points, both marking their largest declines since July 8. This was primarily driven by inflation concerns stemming from a 2.4% rise in Brent crude oil prices to $105.6 per barrel on the day, as well as a nearly 70% probability of a Federal Reserve rate hike in October and a surge in 10-year US government bond yields to their highest level since 2007, leading to broad pressure on global emerging markets. Furthermore, proposed new commission caps by India's domestic insurance regulator further weighed on the financial sector, with PB Fintech plummeting 36% for its largest ever single-day drop. The MSCI Emerging Market Currency Index fell 0.45% on the day, nearing its largest single-day decline in six months, and the MSCI Emerging Market Equities Index dropped 0.9%.
