Extremely unlikely. You are talking about $6 billion in gold at current market prices....or almost 1.5 million ounces. COMEX trades 10-15 million ounces on average. You would crush the market...and other markets, aside from London, can't handle the volume. Sloppy sales or buys can happen but word spreads and any govt trying to gain an advantage would be quickly ID'd and persona non-grata. Tech companies are not fooling around with silver prices.
I imagine it's very similar to the way gas prices spike overnight whenever anyone sneezes near the Middle East, then only sloooooowly drift back down once the "crisis" is "resolved". Something about the terms being set by the folks who benefit from a higher spread...
I wish that was the case here in Nevada, i consider my go to guy on PM,S to give the best price even beating Costco on AGE,S only $30 over spot, you just cant beat that price now SILVER is a different animal all together !
Actually, it's because the replacement cost of oil and LIFO/FIFO accounting differences mandate that you be resistant to pricing on the downside as fast as on the upside. Otherwise, you could be locking-in losses if prices reverse to the upside...or you'd be short the product (oil, gasoline). Same thing with labor: you ask for a raise faster than a cut in your wages (or COLA) depending on the price level. You also have a finished product (gasoline) for which oil is the key input but not the only one. If there was a conspiracy to keep prices high, it would be easier to keep the price of oil high rather than have it fall and give a windfall to the refiners, not the oil companies (who often are NOT refining the product).
