“The notion that reserves are the source of inflows into dollars is a bit dated,” says Brad Setser, the Whitney Shepardson Senior Fellow at the Council on Foreign Relations. In a wide-ranging conversation on the Odd Lots podcast, Setser dismantles popular narratives about petrodollars, de-dollarization, and the 1970s oil shock analogy, offering a more nuanced view of how global financial flows actually work in a moment of geopolitical crisis.

Why the 1970s Oil Shock Analogy Doesn’t Fit

The instinct to compare the current Iran crisis to the 1970s oil shocks is understandable but misleading. Setser points out two critical differences. First, the magnitude is nowhere near comparable: in the 1970s, oil prices doubled or tripled, rising six- to seven-fold in dollar terms by the end of the decade. Today, prices are up maybe 50% from their February lows. Second, the U.S. and Israel are the instigators of this crisis, not passive recipients of an Arab oil embargo. “We sort of started it,” Setser notes. “We in theory can end it.”

Show Notes

It's possible that the war in Iran could reshape financial flows in significant ways. Perhaps the Gulf states will end up as less desirable places to do business. Perhaps Iran will have a tollbooth at the Strait of Hormuz. Perhaps this episode will accelerate the world's shift away from oil. It's impossible to say. But given the uncertainty, fresh questions are being raised about the existing financial world order, upon the top of which the US dollar sits. On this episode, we speak once again with Brad Setser, the Whitney Shepardson senior fellow at the Council on Foreign Relations. We discuss how the war is already creating new global imbalances, and the degree to which this episode parallels past energy shocks. We also talk about broader trends in reserve management, other factors driving financial flows, and the unique situation facing East Asia, which is seeing a surge in its energy import bills at the same time its making making a fortune selling chips for the AI boom.
