This is per day, and equates to 9,020 metric tonnes of gold per day being executed through the London market.

According to the World Gold Council, annual gold mining production was only 2,800 tonnes in 2012 and recycled gold supply only added another 1,600 tonnes, creating annual supply of 4,400 tonnes in total. Given physical supply, then the 9000+ tonnes traded per day is extremely hard to fathom.
