I read a lot...
And I sometimes spend too long thinking about what I read.
I need to get something off my chest, and this seems a good place to do it-
Plenty of opinions on OOF, even if no experts

so:
Precious metals, especially gold, are the only truly universal money - as in, you can go anywhere in the world (and even at any point in history), and swap gold (or silver) for the local currency.
There is approximately a total of 150k tonnes of gold in the world (at £27M per tonne present value) = 4million millions of quids.
The US gold reserve is about 8000 tonnes = 216,000 million quid (call it 100K million dollars)US trade deficit is 500K Million dollars (dec 2010 figures).
if the world suddenly decides that the dollar is no longer worth the paper it's printed on, the US government is going to have to buy a LOT of gold to pay it's debts.
heres the thought that's worrying me -
one theory is, that gold will increase in price against the dollar until the sums balance - ie, until the 8000 tonnes of gold they have in reserve is worth 500K million dollars.
This means gold will raise to about 4,000 quid an ounce, rather than the 850 quid it is at now - 5x increase in price
Another theory is that gold price against a currency is based on the amount of that currency in circulation.
eg - there are 11 million million dollars in circulation.
vs 8000 tonnes of gold in US reserves.
equating to an expected price of 1.375M dollars per kilo as opposed to 43k now (a 32x increase in price).
either way, the theories predict that gold prices are going to sky rocket, and probably soon.
That *could* be why there are so many companies trying to buy as much as they can lay their hands on...
