this article by jake towne indicates tightness in the silver market, providing yet more evidence that physical silver is in short supply:

As we learned in "The Significance of Gold Backwardation Explained (4/5)", backwardation is a sign of a very tight market, and a market that will be tight for sometime into the future either 1) current supply is very tight, 2) future supply is projected to be very tight, or 3) there is a severe distrust in counterparties that the short positions can deliver the goods on time per the contract, or vice versa that the long positions will not have the cash.]

While gold traded as a "store of value" (a currency, really), very little is actually consumed. Silver, on the other hand, serves as both an industrial metal and a "store of value" for silver investors. As we learned here, both silver and gold are precious metals since there is very little aboveground stock. All of the gold stock in the world would fit into a cube 20.5 meters to a side. Due to high amounts of industrial usage, the silver stock is even smaller, less than 14.5 meters to a side.

Please refer to the below graphs of LBMA's silver mid rate, which is the midway point between the bid and offer prices. Here is what I note:

• Silver for all traded futures contracts (whether 1 month or 12 months) have been in backwardation for seven trading days since January 21.
• This backwardation is about three times more severe than the mild backwardation than existed from December 8 through December 24 in 2008.
• We can see that since 2006-2007 where rates were about 4-5%, this state of backwardation is fairly unusual. (The LBMA only lists data back to 2006, but I believe it is a fair comment to say that on an even longer timeline, this is unusual.)
• Furthermore, starting in roughly June 2008, the 12-month SIFO rate flipped over from being the lowest rate to, in general, the highest.
• Also, the disparity between the rates seen in 2006-2007 has largely disappeared; the market appears to be treating a trade on silver 12 months later as quite similar to a trade on silver 1 month later.
