It was post-Cold War and central banks were trimming USD reserves to test alternatives.
Then, crises hit (tequila, Asian, Russian, dot com) and the world reconsolidated around USD, thanks to the immense strength of the Federal Reserve and IMF.
Similarly now, reserve share is falling as countries hedge sanctions and geopolitics, yet dollar usage in trade, debt, and crisis funding remains dominant, and unless a true full-stack alternative (liquidity, safety, yield, and crisis response) emerges, history will repeat.
Makes me wonder: is this just an artifact of the world being relatively "stable" right now?
