Seems like the persicus metal market getting too much distorted between paper and physical price. You have to pay premiums on all the persicus metals, but nothing like palladium.
I used to buy palladium bullions from a US company Southern Coins http://www.scpm.com/goldsilverbullion.php
and used to pay a small reasonable premiums on the spot price. These days the premium is nearly double the spot price. If this is not market manipulation then what is it? The distortion here is getting ridicules, nothing to do with reality.
