There is also a highly likely scenario that Fort Knox and the Federal Reserve have a lot less gold in stock than is advertised.
And way more Tungsten than required.
Just ask the Germans (Gyrsur, are you around?) how long it took to take THEIR gold back to motherland.
EDIT:
Yes, tungsten filled Bullion is a real thing, even for expereinced traders:
How A Manhattan Jeweler Wound Up With Gold Bars Filled With TungstenI've checked when the discussion within the Gov startet to bring home all German Gold (second largest Gold reserve worldwide after United States of America) and it was in 2012.
over 50% ALL of the German Gold was at this time in US (New York), UK (London) and France (Paris). Paris is emptied now but I dont know exactely about London. And our friends in America disagreed about to inspect the Gold Reserve of the German Gold in New York.
but public discussions about that in the German press were suppressed.
EDIT: the plan was changed somehow to "not to bring all the German Gold back". Paris yes fully. New York some Gold and London nothing brought back.

Since the introduction of the euro on both sides of the Rhine, at least for the location of Paris, there is no longer the argument that the gold stored there can be exchanged for foreign currency in a crisis situation. Therefore, this storage location is to be dissolved in the coming years.
That does not apply to New York and London. As a result, only 300 out of more than 1,500 tonnes of gold are shipped from the United States to Germany, while the 35,640 bars in London remain unaffected. There are good reasons for this, as Thiele emphasizes: "Gold can be loaned in the event of a crisis or exchanged for another currency. Therefore, part of the gold remains in the deposits in New York and London."
