Gold slid more than 4% on Friday on rumours the Federal Reserve could get a more hawkish chair, but was still on track for its strongest monthly gain since 1980 as investors flocked to the safe haven amid lingering geopolitical and economic strains. Spot gold lost 3.9% to $5,183.21 per ounce, as of 0323 GMT, after falling as much as 5% earlier. It scaled a record high of $5,594.82 on Thursday.
