The only part of that I didn't know was that the sales were transacted in dollars. I have been following at least headline news in Argentina for a bit over six months now, and since I arrived I've been spending a solid hour reading newspapers, (slowly, haltingly) almost every morning. And I know about the Chinese buyers defaulting on soy shipments, too. You'd think the Argentine soy exporters would be hurting for money.
OK, so, Rich One said-
I suggested a series of steps by which that might happen, and you have both pointed out that wasn't it.
So, looking again at what Rich One said, if the farmers sold their soy for dollars, how does them wanting to buy dollars make sense? They already had dollars, as you've explained it.
