JPM is short of 30,000 contract = 150,000,000 oz Including other banks, commercial banks are short of 65,000 contract = 325,000,000 oz
Well, that means commercial shorts must cover the short position of 325,000,000 oz of silver. That means every $1 silver gains on spot price, they must cover additional $325,000,000 per each dollar gain. JMO
