BENGALURU (Reuters) - Indian shares closed higher on Friday, booking their fifth weekly gain in six weeks as falling COVID-19 cases and surge in vaccinations boosted confidence in an economic recovery. Driven by gains in heavyweight financials, the blue-chip NSE Nifty 50 index ended 0.44% higher at 15,860.35 and the benchmark S&P BSE Sensex rose 0.43% to 52,925.04. Both the indexes added more than 1% for the week in which the country’s vaccinations averaged six million doses per day and some pandemic-induced restrictions were eased. Investor sentiment on Friday was also buoyed by U.S. President Joe Biden embracing a bipartisan Senate infrastructure deal that lifted markets globally. [MKTS/GLOB] In Mumbai trading, the Nifty Bank index rose 1.54%, with private-sector lenders ICICI Bank and Axis Bank being the top two boosts to the Nifty 50. The Nifty Metal Index ended 2.61% higher as Chinese steel and iron futures climbed on hopes of stronger demand due to the U.S. infrastructure deal. [TOP/MTL] Tata Steel was the top percentage gainer on the Nifty 50, adding 4.7%. However, conglomerate Reliance Industries fell 2.3% and was the biggest drag on the Nifty 50.
