Rare rhodium rides 10-year high

- Eddie van der Walt London

Rhodium is on the best run in a decade on expectatio­ns of more demand for the material used in cleaning toxic car emissions.

One of the rarest precious metals, it climbed the past seven months and is up 19% this year, outperform­ing most major commoditie­s. Mostly used alongside palladium in petrol autocataly­sts, prices have rebounded from a 12-year low set in July.

The spectacula­r turnaround comes amid stronger demand from industrial users including vehicle makers, which account for the bulk of rhodium consumptio­n. China, which predominan­tly favours petrol vehicles, raised a sales tax on small cars in December that was less than originally expected. In 2016, Chinese consumers bought vehicles at the fastest pace in three years.

“China is a big part of this story,” said Jonathan Butler, a precious metals strategist at Mitsubishi in London. “The level of car ownership is still growing and there are signs that it could get to western levels.”

The metal is trading at $920 an ounce, according to Johnson Matthey, which makes about a third of all autocataly­sts.

This year’s advance compares with a 13% gain for palladium and a 7.8% increase for platinum, which is also used to curb car emissions. All three metals are mined together, mainly in SA.

One way to buy rhodium is through an exchange-traded product started by Standard Bank in late 2015. Money managers account for most purchases in the fund and private investors make up the rest, according to Johann Erasmus, who oversees the fund.

The product’s assets total about 46,650 ounces, Erasmus said. That is about 5% of total annual demand.

Because rhodium is a smaller market than other precious metals, prices are more volatile, said Grant Sporre, an analyst at Deutsche Bank AG in London. The metal surged almost 23-fold from 2003 to 2008, when it touched a record $10,100.

“There’s currently no reason to expect falling prices in the short or medium term,” Heraeus Metals Germany GmbH & Company said in a report e-mailed on Monday. / Bloomberg
