Petrodollar recycling

Petrodollar recycling is the international deployment of a country's revenue from petroleum exports. It generally refers to the phenomenon of major petroleum-exporting nations – mainly the OPEC members and Russia – earning more money from the export of crude oil than they could feasibly invest in their own economies. The resulting global interdependencies and financial flows, from oil producers back to oil consumers, can reach a scale of hundreds of billions of US dollars per year across a variety of currencies, heavily influenced by government-level decisions. The phenomenon is most pronounced during periods when the price of oil is historically high.
