Singapore: Palladium climbed above $1,000 (Dh3,673.30) an ounce for the first time since 2001 as global demand grows for the metal in catalytic converters used by gasoline-powered vehicles.

Prices jumped as much as 1.6 per cent to $1,007.42 on Monday, before trading at $1,005.57 by 8.48am in London. The metal is one of this year’s best performing commodities, advancing 48 per cent, more than three times the increase in gold and about 10 times the gain in its sister metal platinum.

“Palladium continues to be driven by the positive momentum created by expectations of a supply deficit amid rising demand,” Ole Hansen, head of commodity strategy at Saxo Bank A/S, said by email. Industrial metals have risen this year as the world economy recovers, and copper burst through $7,000 a metric ton on Monday for the first time since 2014.

The metal became more expensive than platinum last month for the first time in 16 years. The latter is used to cut pollutants from diesel vehicles, which are now less popular, particularly in western Europe, after some automakers admitted to cheating in emissions tests.

Things could get worse for platinum. European diesel-engine market share could halve by 2025, potentially removing 300,000 to 600,000 ounces of platinum demand over the next 10 years, according to Citigroup Inc Palladium, on the other hand, is expected to remain in deficit, although it will begin to ease over the long term, the bank says.

Citigroup sees global surpluses in platinum stretching out to 2020, while the shortfall in palladium is set to widen to more than a million ounces next year before narrowing to 750,000 ounces by 2020, the bank said.

“Despite the PGM spread inversion since the end of September, we remain favourable to palladium over the short term,” Citigroup analysts including Nell Agate wrote in a note dated October 13. “However, ever-looming substitution risks prevent an outright bullish view on palladium over the long-term.”

United Overseas Bank Ltd said last week that it expects growing demand for gasoline emission-control devices to support palladium and continue to fuel outperformance over platinum.

European car sales growth accelerated in August as an expanding economy encouraged purchases and French manufacturers PSA Group and Renault SA won buyers with new SUVs and hatchbacks. Car sales are set to rise further this year as manufacturers offer incentives to trade in older diesel cars for models meeting tighter pollution standards amid German government pressure stemming from Volkswagen AG’s emissions-cheating scandal.
