There are 4 individuals sitting in a company in US. I dont remember the name of the company.
These 4 individuals has the only job of handling the supply of Gold across the globe. You will not believe the prices of Gold are decided by them.
If they want prices to go up, they restrict or slow down the supply of Gold which in turn, increases the demand of Gold in Indian market or in any other market and hence prices go up.
This way Gold prices are managed and Gold keeps on shining.
