Gold reserve

[note 1] During most of history, a nation's gold reserves were considered its key financial asset and a major prize of war.

A typical view was expressed in a secret memorandum by the British Chief of the Imperial General Staff from October 1939, at the beginning of World War II.

The British Military and the British Secret Service laid out "measures to be taken in the event of an invasion of Holland and Belgium by Germany" and presented them to the War Cabinet: It will be for the Treasury in collaboration with the Bank of England, and the Foreign Office, to examine the possible means of getting the bullion and negotiable securities into the same place of safety.

The total weight of this bullion amounts to about 1800 tons and its evacuation would be a matter of the utmost importance would present a considerable problem if it had to be undertaken in a hurry when transport facilities were disorganized.

Following the outbreak of war, the gold held in France was sent to Dakar, the capital of Senegal, then part of the French colonial empire.

The Banque de France fully compensated the Belgian National Bank for the loss of its gold after the war.
