In the main commodity markets, nothing is doing better than palladium this year.

The metal is up 30%, beating 33 other raw materials, including lean hogs and aluminum, tracked by Bloomberg. On Friday, prices surged as much as 7.9% to a 16-year high of $928.36/oz as some traders were said to scramble to get hold of physical supplies.

Palladium, which is mainly used to curb harmful emissions from gasoline vehicles, has rallied on expectations that supply will lag demand for a sixth straight year. It’s now almost as expensive as platinum for the first time since 2001, helped by Volkswagen’s emissions scandal two years ago that has prompted consumers to switch from diesel to gasoline cars.

“The fundamentals in palladium are among the best in all the commodities,” said Rene Hochreiter, an analyst at Noah Capital Markets in Johannesburg. “It could easily overtake platinum in the near-term. It feels as if the rally has got legs.”

SUPPLY DEFICIT
Mine production hasn’t been able to keep up with usage since 2012, partly because of rising car sales and stricter emissions limits. While stockpiled metal probably helped feed consumer demand in recent years, that source of supply may now be running out, according to Caroline Bain, chief commodities economist at Capital Economics.

RUSH TO BUY
The futures market is signalling traders are rushing to buy metal. Palladium for June delivery in New York has become a lot more expensive than the March 2018 contract in recent weeks. That’s indicating there may be concerns about near-term supplies.

“It appears that there is a serious shortage of readily available physical bars for spot settlement,” said Brad Yates, head of trading for US gold refiner Elemetal.

PARITY TO PLATINUM
Palladium’s rally means it’s almost the same price as sister metal platinum, which is favoured in catalytic converters in diesel vehicles. But because the metals can be used interchangeably, analysts have said that some industrial consumers may consider switching from palladium into platinum.

NOT EVERYONE'S SO BULLISH
But exchange-traded fund investors aren’t as keen. Palladium assets are down about 50% from a peak in 2014, data compiled by Bloomberg show. While holdings have fallen this year, they’ve increased in gold, silver and platinum ETFs.
