Palladium’s great start to the year pales in comparison to its lesser known, but much more expensive sister metal, rhodium. Rhodium – mainly used in autocatalysts and five times more costly than gold – surged 32% already this month, touching the highest since 2008. Stricter emissions rules have fueled a multiyear rally and there’s speculation that investors are also jumping in, betting that prices will climb toward a record.
