Dollar colonisation: The destructive policy implications of modern monetary theory

Modern monetary theory argues that all governments that issue their own currency have the same policy space. The present paper argues that this position is wrong. For it to be valid, abstraction must be made from the gravitational force of the US dollar that stems from its backing mass of securities and is transmitted through international investment flows. On recognition of this gravitational force, it becomes clear that the huge size disparity separating the US financial market from those of other markets, and most notably those of the EMEs, translates into an equally huge disparity regarding policy space. The policy implications for EME governments are that they should, where possible, join their financial markets into regional blocs of sufficient sizes as can give their regional currencies enough backing mass to allow them to resist the gravitational pull of the dollar. Only by pooling their currency sovereignty can EME governments retain some scope for pursuing policies independently of those pursued by the US government. On the contrary, any such scope is destroyed if EME governments in countries with small financial markets follow the MMT's advice to retain their local currencies because that advice condemns these currencies to entrapment in the dollar's gravitational field and even possibly to outright dollar colonisation.
