The Bundesbank is to repatriate gold reserves held abroad in order to tighten control and combat future currency crises. It will repatriate a large percentage of its holdings from New York and all of its bullion from Paris.
This move signals the demise of the the Dollar as a reserve currency (as the gold stored in the Fed can be pledged to shore up the Dollar), and the resurgence of a quasi gold standard.
The lesson is clear, if you invest in gold do not rely on mere paper certificates to validate your holding.
