Originally "petrodollar" was just a name for dollars that are used for oil trade, but then someone came up with a theory that all USD value holds on this oil trade, and if countries will switch to other currency, USD will collapse. This theory completely ignore all other international trade conducted in USD, which is far bigger than just oil trade.


That's also a narrative without proper backing, why would US economy collapse if international trade will switch to other currency? Inflation alone can not kill economy, and it's not even clear that the supposed dedolarization will cause massive inflation.
