BIS Changed Silver Data

This means that the $203 billion silver liability divided by $15/oz. shows that all the banks in the world that are tracked by the BIS owed 13.5 billion ounces of silver.

But the entire world silver mining production is only about 700 million oz. of silver annually, so this is an admission that the banks owed about 19.3 years worth of world annual mine production of silver.
