The goal: neutralize crude oil as an economic weapon and find a way to persuade a hostile kingdom to finance America’s widening deficit with its newfound petrodollar wealth. And according to Parsky, Nixon made clear there was simply no coming back empty-handed. Failure would not only jeopardize America’s financial health but could also give the Soviet Union an opening to make further inroads into the Arab world. ... The basic framework was strikingly simple. The U.S. would buy oil from Saudi Arabia and provide the kingdom military aid and equipment. In return, the Saudis would plow billions of their petrodollar revenue back into Treasuries and finance America’s spending. ... The current tally represents just 20 percent of its $587 billion of foreign reserves, well below the two-thirds that central banks typically keep in dollar assets. Some analysts speculate the kingdom may be masking its U.S. debt holdings by accumulating Treasuries through offshore financial centers, which show up in the data of other countries. ... While oil’s collapse has deepened concern that Saudi Arabia will need to liquidate its Treasuries to raise cash, a more troubling worry has also emerged: the specter of the kingdom using its outsize position in the world’s most important debt market as a political weapon, much as it did with oil in the 1970s.
