How the 1970s Oil Shock Fueled a New Dollar-Based Global Order

In August 1971 President Nixon announced the closure of the gold window, ending the dollar’s convertibility and collapsing the post-World War II Bretton Woods framework, a decision heavily influenced by Vietnam-war spending and expanding deficits. The break-up of the system coincided with the 1973 Arab oil embargo, which sent crude prices sharply higher and triggered a global cost shock that hurt consumers and trade balances.

To capitalize on the new reality, the United States negotiated a clandestine 1974 agreement with Saudi Arabia, offering military support in return for Saudi reinvestment of oil revenues in U.S. Treasury securities, thereby creating the petrodollar recycling system. This arrangement gave the dollar a fresh anchor, allowing Washington to fund further conflicts and preserve its reserve-currency status while oil companies, banks, and defense contractors profited.

Simultaneously, right-wing economists seized on the stagflation episode to argue that welfare spending and unions were to blame, steering policy toward austerity, deregulation, and neoliberal reforms. The legacy of those choices continues to shape debates over inflation, monetary sovereignty, and the distribution of economic power.
