Quote from Anaconda:
Aside from Ivanovich said, which has merit.
A) Industrial use of silver has actually went down over the decades, mainly due to digital photography. Gold's has actually went up due to computing.
B) Heavy shorting of the silver futures by JP.Morgan and Gang.
C) The physical premium on silver over spot is at least 4 times the one on gold. So when you go in the bullion market to get silver & gold, silver is priced higher than on the paper market, relative to gold.
Not true.
Even though silver use in photography has gone down, we are still using up the same amount of silver every year.
Silver mines around the world have produced on average 617 million oz per year for the last 10 years, yet for the last 10 years we have used on average 885 million oz per year.
If everyone in the world went digital and nobody used silver for photography starting tommorrow, we would still be running a silver deficit of about 150 million oz per year at least. Today photography is probably only about 10% of what we use silver for.
