The holdings at the iShares Silver Trust (NYSE:SLV) have been climbing recently, some 129 tonnes of the metal added in just the last seven days, as the price of silver has surged from under $18 an ounce to more than $19.50 with more upside likely ahead.

At 9,280 tonnes, the inventory is still a bit short of the high seen in late-2009 at 9,514 tonnes, but, with the price of silver rising as it has been, that could change very quickly.
