The current premium is due to price gouging of the ignorant retail client by bullion dealers...
This is what the "debate" is about - the premium being due to price gouging - rather than a bottle-neck in supply caused by unprecedented demand.
As I have mentioned previously, a simultaneous increase of premiums makes absolutely no sense from a business stand-point, without the existence of supply disruptions. We aren't just seeing higher premiums, we're seeing listings being removed entirely. This is where your "price gouging" theory runs out of steam.
I don't doubt that there is physical gold out there, nor do I doubt there is physical silver.
But gold and silver are becoming increasingly more difficult to take delivery of in physical form and this, in my view, has everything to do with a supply bottle-neck causing a trickle down effect from the refineries to the dealers. Hence why Perth mint and ABC Bullion still have some listings while other lower tiered dealers have little to none.
The thread title is "Why are we seeing Spot and Physical spreads widen". I completely disagree that it is due to price gouging and the logical explainations for you holding this position are lacking.
Buying unallocated or paper silver which has a convertibility option still won't result in the physical asset being acquired any sooner than buying Gold or Silver on backorder. You're also still going to be paying a minting fee equivalent to the premium/spread from spot to physical.
Using ABC as an example, you pay a small premium over spot for allocated metal. If you want to take delivery, you pay an equivalent fee relative the the premium/spread of whatever bar or coin you desire. If you wanted to take delivery, you would still need to go to the back of the pre-order queue and wait the same amount of time as if you purchased on backorder in the first place.
Because of the initial low premium you pay to buy allocated or unallocated, you would actually be worse off if you decided to take delivery of the product. The only time it's advantageous is if you held your allocated/unallocated storage until the premiums returned back to normal, and even then it wouldn't be much of a difference.
