Here is the best piece on the dollar as reserve currency and how it works to give the US an artificially high standard of living. Hey, it was a nice run that was bound to end at some point. Hopefully we don’t start a war to keep getting our free lunch.
The vast expansion of US-led globalized trade since the Cold War ended in 1991 had been fueled by unsustainable serial debt bubbles built on dollar hegemony, which came into existence on a global scale with the emergence of deregulated global financial markets that made cross-border flow of funds routine since the 1990s.
Dollar hegemony is a geopolitically constructed peculiarity through which critical commodities, the most notable being oil, are denominated in fiat dollars, not backed by gold or other species since then president Richard Nixon took the US dollar off gold in 1971. The recycling of petro-dollars into other dollar assets is the price the US has extracted from oil-producing countries for US tolerance of the oil-exporting cartel since 1973. After that, everyone accepts dollars because dollars can buy oil, and every
economy needs oil. Dollar hegemony separates the trade value of every currency from direct connection to the productivity of the issuing economy to link it directly to the size of dollar reserves held by the issuing central bank. Dollar hegemony enables the US to own indirectly but essentially the entire global economy by requiring its wealth to be denominated in fiat dollars that the US can print at will with little in the way of monetary penalties.
