Where is the largest physical gold reserve? This will almost certainly change in the coming years as Russia and many Asian countries continue to accelerate their rate of physical gold buying. Currently, the US Federal Reserve Bank in New York is considered the largest single gold storage facility (not Fort Knox!) holding approximately 6,800 tonnes of gold, a total of approximately 540,000 gold bars – over 25% of the world’s gold! Although, it’s important to note that most of this gold is actually owned by foreign governments.
