I haven't checked them, but probably will to the extent I'm able to this evening.
It mostly feels about right.
There are $30 trillion in currencies worldwide.
All the gold ever mined would fit in a 62.3 ft. cube.
All the gold ever collected, panned and mined since the time of Jesus is worth approximately $7 trillion at today's price.
There are 158,000 tonnes of gold above ground, 86% of which is held by central banks, investors, and jewelry owners.
This means there are 4.8 billion ounces of gold above ground globally, of which 2.1 billion ounces, 43% is in jewelry, religious and art items, official reserves of 1 billion ounces, industrial use of 530 million ounces, and 1.1 billion ounces in private hands.
The market cap of all gold that is above ground, including central bank reserves (30,717 tonnes as to 10/11), is equal to only 1.4% of global financial assets. Combined central bank gold reserves rose in 2009 by 425.4 metric tons to 30,116.9 tons, an increase of $13.3 billion (2009 average prices), the first increase since 1988.
Central banks hold 18% of all the world’s gold ever mined.
