 "Palladium")
Palladium pierced the $3,000 an ounce high for the first time on Friday, powered by persistent concerns about short supply of the metal used primarily for emissions-controlling devices in automobiles.
Palladium was last up 1% to $2,984.68 per ounce, after hitting an all-time high of $3,007.73. It was on track to post a monthly gain as well.
"Palladium is in a structural deficit since 10 years. We have seen above ground inventories falling to very low levels, and now the price gives a signal to investors still holding it," UBS analyst Giovanni Staunovo said.
"The commodity ... comes with very low trading volume so it can be very illiquid and this is making the moves even more crazy. This rally can continue, particularly if car sales start to improve going forward."
Demand from the auto industry is rising and expected to climb further as a semiconductor chip shortage that has curtailed vehicle production eases later this year.
