It is a frustrating and often woeful outcome, but deference isn't a reason to color judgement. As an investment, which is more like what gold has become, it isn't all that straight, either. Gold behaves in many circumstances erratically; often violently so. In 2008, gold crashed three times; but it also came back (and then some) three times. The metal remains stuck in some orthodox limbo of duality, sometimes acting an investment while at others, more rarely, as almost reclaiming its former status.

The junction of that dyad format is wholesale collateral. It is a difficult and dense topic because it plumbs the very depths of the wholesale arrangement – factors like leasing, swaps and collateralized lending through binary bespoke arrangements. It is there that I think it helps to form the narrative, however, starting by reviewing what the BIS was up to in late 2009 and early 2010. I am going to borrow heavily from an article I wrote in April 2013 that describes the events in question but this is one of those times when you should read the whole thing.
