ARMCO Part II:

The Petrodollar System and the Expansion of Saudi Financial Power (1970s–2000s)

Following the 1973 oil crisis and the nationalization of ARAMCO, Saudi Arabia accumulated unprecedented financial reserves. These reserves flowed back into the United States through the petrodollar recycling system, in which Saudi oil revenues were reinvested in U.S. banks, Treasury bonds, defense contracts, and major financial institutions. This system deepened the structural interdependence between the two countries: the U.S. relied on Saudi capital to stabilize global financial markets, while Saudi Arabia relied on U.S. security guarantees and access to American technology. Over time, this arrangement blurred the boundaries between public policy and private capital, creating a political economy in which state wealth, corporate interests, and geopolitical strategy became increasingly indistinguishable. The petrodollar era thus laid the financial and institutional groundwork for the twenty‑first‑century expansion of Saudi sovereign wealth into new sectors—most notably, technology. ^2
