The available stock, therefore "registered," and assuming the banks are acting in good faith and haven't misrepresented their figures, is approximately 1057 tonnes, or 34 million ounces. The total market capitalization of silver is approximately 30 billion, so a perfect cube of approximately 4.65 m³ is actually supporting 30 billion dollars ? Without counting all the options which represent approximately 100 billion ?
