The gimmick here was that there was no actual URV currency. No notes or coins, no bank accounts denominated in it. This prevented developing a free-market exchange rate that undermined the abstract value the state was trying to establish.

I could say "I'm only willing to pay 0.50USD for 1URV". If someone takes me up on it, the fulfillment would have to take place in cruzieros-- the transaction becomes "I'm paying 0.50USD to 15 cruzieros" or whatever. This sort of transaction would have more impact on the cruziero's exchange rate than the URV's.

I could imagine trading some sort of "osudeo-URV" derivative product that was basically a prepaid purchase contract, but its value would be heavily affected by cruziero-related risk.
