BENGALURU, May 20 (Reuters) - Indian shares were weighed down by metal stocks on Thursday, after China sought stricter control of commodity markets to curb “unreasonable” increases in prices, sparking a broad-based correction. Both the NSE Nifty 50 index and the S&P BSE Sensex traded in a narrow range as Asian peers paused with investor risk appetite declining over inflationary worries. Investor sentiment, which was upbeat at the start of the week, took a hit on Wednesday after global stocks receded. By 0409 GMT, the Nifty 50 was down 0.22% at 14,989.55 and the Sensex was 0.08% lower at 49,865.05, dragged down by a near 4% drop in metal stocks - the most among sectoral indexes - after China said it would step up adjustments on the trade and stockpiling of commodities. Minutes from the U.S. Federal Reserve’s last policy meeting flagged the possibility of a debate on scaling back asset purchases, sending U.S. shares lower overnight. Among gainers, lender ICICI Bank and IT major Infosys rose nearly 1% each. Meanwhile, India’s new coronavirus infections stayed below the 300,000 mark and deaths backed off from record highs.
