BENGALURU: Indian shares posted broad-based declines on Friday, pressured by foreign fund outflows, and as global central banks took a hawkish stance and warned of surging inflation.

The NSE Nifty 50 index fell 1.53% to 16,985.20 and the benchmark S&P BSE Sensex dropped 1.54% to 57,011.74. Both the indexes shed nearly 3% this week after two consecutive weeks of gains.

"The emergence of a new COVID-19 variant, Omicron, inflation concerns and a hawkish turn of global central bankers have led to an increase in volatility in equity markets worldwide, including India," said Shibani Kurian, head of equity research at Kotak Mahindra Asset Management Co.

"With inflation increasing in countries across the world, all eyes are on central bankers and the pace of liquidity normalisation adopted by them."
