This will be the last article I’ll write on the subject of the rubles for gas deal that went into effect on April Fool’s of 2022—until something dramatic happens. As far as the dramatic event that has already happened (the emergence of the ruble as the world’s only energy-backed currency) the picture was fuzzy at first but has by now come into very sharp focus. Russia’s plan is as simple as it is brilliant: the EU nations (a.k.a. “unfriendly nations” in contemporary Russian official terminology) may continue to pay for gas in euros; all they have to do is open specific (K-type foreign currency) bank accounts in a specific Russian bank (Gazprombank, which is not under any sanctions). Gazprombank will then exchange these euros for rubles on Russia’s internal foreign currency market and deposit the proceeds (if any) into corresponding (K-type ruble) accounts. It will then transfer these rubles to Gazprom, which will then let flow a corresponding quantity of natural gas. Superficially, nothing has changed; the Europeans are still paying for Russian natural gas in euros and the rest is some Byzantine Rube Goldberg that Putin has thought up and makes no difference to anyone but him. Right? Wrong! This is a trap! Please allow me to explain.
