The price of rhodium, a metal used in fine jewelry and car parts, has skyrocketed over the last few months. It has jumped by more than 50% in just the first three weeks of January, reaching a price more than six times that of gold and the highest since late 2008, FactSet data show.
What's happening: "Surging demand from carmakers is partly to blame," the Economist writes. "More than four-fifths of global demand for both rhodium and palladium comes from the automotive industry. The metals, together with platinum, help convert toxic gases in a vehicle’s exhaust system (such as carbon monoxide) into less harmful substances before they exit the tailpipe."
