according to coin update news, silver stockpiles are being drawn down:

a high percentage of the withdrawn silver has apparently been from two specific depositories, not just all of the COMEX depositories in general. Those who have studied the details closely state that the banks losing the bulk of silver have been Scotia Bank and HSBC.

Scotia Bank has been rumored for many months to have very little physical precious metals in its vaults to cover customer deposits. This can be done, in theory, if the bank owns derivatives to cover their short physical position, but these derivatives are only as good as the other party’s abilities to deliver on demand in event of a possible Scotia default. There is not really any hard and fast information to prove that the derivatives are worth the paper they are printed on. In fact, since the total amount of extant silver derivatives exceed many years of silver mining production, let alone the much smaller amount of available above ground inventories, there is a huge reason to be fearful that the paper silver market could be heading for a crash in the near future.

On one day in June, there were 630,000 ounces of silver withdrawn from other COMEX depositories on the same day that 610,000 ounces were deposited at Scotia Bank. This seems more than coincidental. It looks suspiciously like an emergency transfer from another depository to help Scotia Bank avoid default on making delivery that day.

If this drain of COMEX silver inventories continues, it could literally be the spark that brings down the entire global financial system, Any indication that owners of “paper” silver may not be able to convert their paper into the physical product will only increase the demand to do just that.

As I said five days ago, this run won’t be confined to the silver market for long. Owners of paper gold will see what is happening and almost certainly step up converting their paper into physical metal. By the way, the COMEX recently reported that physical delivery of maturing gold contracts thus far in 2010 is running 39% higher than for the same period of 2009. The parties facing the largest potential losses are naked sellers of gold and silver commodity contracts, where there is no physical inventories to fulfill their liabilities. The entities with such huge positions are major banks. As gold and silver (and probably platinum, palladium as well as many other metals) prices rise because of the supply squeeze, it could easily happen that many major banks and central banks could go bankrupt.
