But consider this – the gold owned by the people of India far outweighs their national gold reserve.
"There is no sure way to tell, but going by our rate of gold imports in the last 20 years and India's cultural and traditional attachment to the metal which dates back to over 2000 years (might I add, unlike most other countries, obtained fairly by trading in spices, silk and education) it is highly probable and likely that India has physical possession of more above ground (mined) gold than any other country in the world and unverified sources claim that this could be upto 20-25% of the gold ever mined (~170000 tonnes)."
