In 2009, total COMEX registered silver supplies were 87.4 million ounces. Fast forward to May 2011, and registered silver supplies are now 33.2 million ounces.
This is a drop of 54.2 million ounces in registered silver supplies in 2 years, or an average drop of 27 million ounces/ year!
Translation: the end game in the silver manipulation may well arrive in the next year.
