So overall, between the 9,000 tonnes quotation in 2011, and the 6,256 tonnes 2015 quotation, some 2,750 tonnes (~ 220,000 Good Delivery bars) disappeared from the London gold vaults. With 6,256 tonnes of gold stored in the entire London vault network in 2015, and with 5,134 tonnes of this at the Bank of England, that would leave 1,112 tonnes of gold in London outside the Bank of England vaults.
