Does triffin dilemma also counts for a basket of currency? Like the imf special drawing rights or keynes bancor idea.
Since the 16th century central banks (or whatever version of it existed) one countries foreign currency reserve was sacrosant and enjoyed sovereign immunity. In the last few years the US has done this with Iran, Venezuela and Afghanistan.
Russia feared their USD denominated reserves could be confiscated because the US had already done the "unthinkable", i.e., stole someone else's money which enjoyed sovereign immunity.
Russia did not count that the "collective west" would dare commit such sin. But.... but.... they did.
As such, NOBODY ELSE will trust their foreign exchange reserves will be safe.
People may not realize, but the whole international financial, trade systems have come down with that theft.
The evil genie has been released from the bottle.
I repeat, NO COUNTRY TRUSTS KEEPING THEIR SAVINGS in USD, Pounds, Swiss Francs, Yens anymore.
If I were to define the policies pertaining to the savings of any country I would transform all my savings in commodities (mostly metals and oil).
Anytime you needed some cash to cover any trade or current account deficits, I would just get some of those commodities and sell them in the market for pocket cash(country sized pocket cash).
