He does a great job of explaining what is happening with Silver.
COMEX Just Triggered Its Own Margin Call—Silver Deliveries Are Eating the System | Andy Schectman
Right now the ratio of Paper contracts for silver to those who want to take delivery is around 200:1. Now to sell someone silver on paper you have to actually pay a lease rate for the silver. When silver didn't rise in price the lease rate was very close to 0 so it was easy to sell people silver, it didn't cost you anything. But now the lease rate is up around 7%! That is huge, all these people who have sold paper silver are now paying through the nose and so they are being forced to buy it back. Now as they buy it back the price climbs and so the lease rates also go up and if the lease rates go up more and more people are forced to buy it back. This is the death spiral.
Think of this as the first stage in a rocket ship taking off.
The second stage is all those people who have accumulated massive positions in silver over the last fifty years will be able to simply put up the silver they own as collateral for margin and they can double their position. Once you have cleared the decks of all overhang you can do this. The price will skyrocket and so you can immediately short it with a huge short position, four times what you bought causing the price to go much lower and making the volatility go crazy.
Let me show you the math.
You have 100,000k ounces of silver, put it on margin buy another 100,000k ounces of silver, so you now have 200,000k ounces of silver. The average price for the entire 200,000k ounces is 70$ but the price spikes to $100 at which point you can sell the 200,000k ounces you have and another 200,000k ounces you short, selling 400,000k ounces. Because everyone else is trying to jump on the bandwagon as you sell you do OK at first, but the average daily float is 200,000k ounces of silver, so there are not enough buyers for your 400,000k ounces sold and so the price does drop precipitously. You are unable to sell the first 200,000k ounces above an average price of $70 so you made a big profit on that, but then the price drops all the way back down to $50 where support kicks in and now you are in a position to buy 800,000k ounces of silver at a big discount as you ride this back up far beyond $100.
Now to have the original 100,000k ounces of silver you must own $5 billion worth of silver. This is central bank levels or hedge fund levels. However, if you acquired the first 100,000k ounces at an average price of $10 over the last thirty years then you spent $1 billion over 30 years, or 33 million a year, to get to $5 billion.
