I do understand that there needs to be caution when using historic ratios. Even with the long history of using gold and silver as money, you will find a wide divergence of views regarding the proper ratio between gold and silver. So we also do NOT have a SOLID ratio for gold/plat, silver/plat, etc. True the Au/Pt ratio may get larger before it swings back toward historic levels. But I think that gold is being driven as much by fear and speculation as anything else. People (who have never owned gold before) are being urged to "invest". As I mentioned in the previous post, bullion is more of a hedge against loss than it is an investment for "profit". I do not hear nearly as much hype encouraging "investors" to buy Pt Pd Rh or even oil. But they also can be a hedge against inflation. (interesting to watch the gold to oil ratio, recent history at 10:1) So, ? Is the Pt price more realistic (to industrial demand) since it has less of a "fear factor" adding to the current spot? Pt spiked a few years back when the SA mines were having electrical power disruptions. World production was ramped up leading to an alleged current oversupply. Auto manufacurers may have also begun to hoard as a precaution. Demand may increase in the near future. BTW: Pt is used primarily for gasoline engines, while Pd is more applicable for diesels.
