I heard an interview on radio from a just retired 'top banana' in the intrenational banking field. His opinion was that the World economy will remain flat for a very long time.
If he is right, (and I am not saying that he is), I would guess that PM prices will also remain flat, over the same period (whatever length of time that is).
On that basis, my prediction for silver is current price + or - $5, in 2012.
By all means accumulate silver if that is your thing, but there may be other better investments.
I am watching World inflation rates like a hawk just now.
In the distant past, I have done well by paying back loans with inflated (and therefore less valuable) inflated money. Just remember that what you buy with a loan will have lasting value for an indefinite period.
Silver, for an example, may be one of those things. Howver, WOULD NOT buy PM's with loan money at current inflation rates. Too risky just now, may be OK with higher inflation rates.
