Why does the world buy oil using U.S. dollars — even when that oil comes from thousands of miles away? In this episode, we explore the rise of the petrodollar system, a powerful financial arrangement born from Cold War politics, energy crises, and global economic change. From the collapse of the gold standard to the oil shocks of the 1970s, discover how oil revenues helped cement the dollar as the dominant currency in world trade — and why new economic powers, digital currencies, and the global energy transition could challenge that dominance in the years ahead. This is the story of how barrels of oil helped shape modern financial power — and what happens if that system begins to shift.
