It has been reported that global debt is about $200 Trillion. Central banks supposedly hold about 30,000 tons of gold. If the total debt were backed by central bank gold at 40%, that would price gold about $80,000 per ounce. In the US, the official gold reserve, which has not been audited in about 60 years, is about 8,200 tons. Official national debt is about $18 Trillion. If the official gold backed the debt at 100%, the price of gold would be about $70,000 per ounce.
