Since the beginning of 2009 there have been 9,030 tonnes of gold taken out of the Shanghai Exchange into China.
That is more than 290,320,000 troy ounces of fine gold in bars.
Just for the sake of comparison, as shown in the last chart below, the total official holdings of the United States are about 261,498,926 ounces of gold.
So it does seem that since 2009 more gold has been withdrawn from the Shanghai Exchange than is in all the official holdings, vaults, forts, mints and Federal Reserve Banks of the United States.
