Anyone can offer an opinion to this question.
Is the price of gold ( or will the price be ) linked to the cost of production? If gold tanks further who would bother digging the stuff up? AISC for most producers is moving past $1000 per ounce. I'm not even going to attempt to offer an opinion using economics but if we accept that gold is still considered valuable ( although I'm sure some would like to debate that also) around the world mines will be put care and maintenance everywhere. I understand that the price is just traded like any other commodity and so is open to traders but at some stage the supply and demand curve has to be relevant ( OK economics 101).
I'll leave you more learned students of economics with this.
“Economics is the only field in which two people can share a Nobel Prize for saying opposing things.” Specifically, Myrdal and Hayek shared one.
