Gold is heading for a third weekly advance, with the haven metal gaining on anxiety about the spread of Covid-19 variants and prospect of prolonged dovish monetary policy. Bullion is winning back investors after a bleak June, with fears the world’s exit from the Covid-19 pandemic may be more fraught than anticipated. Renewed virus fears are a boon for bullion because governments may have to extend monetary support to still-fragile economies. Those risks were underscored this week by US Federal Reserve minutes that highlighted continued uncertainties and a rise in US jobless claims. China’s surprise hint that it could unleash more liquidity to the economy also added to the sense that headwinds to a global recovery remain strong. “Commodities came under pressure as policy makers around the world flagged risk to their economies from rising cases of Covid-19 variants,” Australia & New Zealand Banking Group said. “Demand for safe haven assets rose following a lift in US initial jobless claims.”
