This principle is frequently called the " impossible trinity ," "unholy trinity," "irreconcilable trinity," "inconsistent trinity," "policy trilemma," or the "Mundell–Fleming trilemma ." Free capital flows can put economies in a bind Free capital movement has since become one of the axioms of modern global capitalism. a fixed exchange rate and an independent monetary If the exchange rate is fixed but the country is open to cross-border capital flows, it cannot have an independent monetary policy (side A). And if a country chooses free capital mobility and wants monetary autonomy, it has to allow its currency to float (side B). The policy constraint following from free capital movements has recently been posed in a more severe form by Rey (2013), who shows that in a globalised world of free capital movements, monetary policy is limited even with flexible or floating exchange rates.
