While the trading world was focused on the latest news involving Deutsche Bank, namely that the troubled German bank had been contemplating a merger with Germany's other mega-bank, Commerzbank as part of a strategy to sell all or part of a key business to speed up its flagging overhaul, a more troubling report emerged in a German gold analysis website, according to which Deutsche Bank was unable to satisfy a gold delivery request when asked to do so by a client of Germany's Xetra-Gold service.

But first, what is Xetra-Gold?

According to its website, the publicly traded company "provides investors with an efficient instrument to participate in the performance of the gold market. Xetra-Gold’s combination of features – cost-efficient trading and the right for physical delivery of gold - makes it an attractive product."
