If Silver Is A Bubble, Why Are Vendors Running Out Of Bars?

I have already written about the fact that the price of taking physical possession of silver did not drop nearly as much as the spot price of silver last week, as a comparative percentage.
Check this morning for 1oz silver bars on APMEX. Almost all types of 1oz silver bars are either back ordered or out of stock. If you are used to buying 1oz silver bars on ebay, go check it out today. There are 1oz bars but they are selling at $13 over spot. In addition, if you are used to watching silver on ebay, you will notice there are far less bars for sale now than a month ago. Most of the bars for sale now are “silver clad art bars”, which are silver plated junk bars designed by some Chinese scam artists to rip off first time silver buyers.
I have also noticed that the 5oz silver bar supply is starting to tighten up. All of this reflects what I feel is the real driver behind silver. Average people are starting to realize that it may be a bad idea to have all their money tied up in paper currency and there is a natural correction back to precious metals as a currency.
As for the people who buy the paper shares of silver in popular ETF funds, I have a distrust of this idea. A large driver of the silver movement is people wanting to get out of paper. If a major shock hits the markets and people realize that the silver ETF funds don’t have enough silver to physically cover their paper, the stock will become worthless. I may be old fashioned, but I like to have some portfolio protection in silver and gold that I can hold in my hand.
