Episode summary
Is the Dollar Losing Its Luster?
Wall Street Week
· · Guests: Kenneth Rogoff
Summary
Ken Rogoff argues that the dollar’s dominance is not disappearing overnight, but the Iran conflict is another force pushing the global system toward a slower, more multipolar decline. He says the war could matter both ways geopolitically, but either outcome would only accelerate trends already underway: China is likely to push harder for yuan use in trade, while higher military spending and higher global interest rates add pressure to a U.S. economy already burdened by large debt and weak fiscal will.
Rogoff says military power still matters to currency dominance because it shapes negotiations, confidence, and the incentives of allies such as the Gulf states. But he warns against overstating the petrodollar: oil pricing is flexible, while the bigger issue is whether manufactured goods, debt, and financial contracts are increasingly denominated outside the dollar.
He says the dollar still dominates short-term debt and global liquidity, yet its special premium on longer-term borrowing has faded. In his view, the erosion is visible in reserves, spreads, and efforts by Europe and China to build independent systems, even if the private sector remains heavily dollar-based.
Key takeaways
- Rogoff says the Iran war will likely accelerate, not reverse, the dollar’s gradual decline by pushing China and others toward alternatives.
- He argues the U.S. is vulnerable because it is the world’s biggest debtor and higher global interest rates raise America’s financing costs.
- Rogoff says military strength still supports currency dominance because it affects negotiations and allies’ confidence.
- He says the dollar remains the main currency for short-term debt and FX trading, but its long-term debt premium has largely disappeared.
- Rogoff sees Europe and China building separate financial systems as evidence that de-dollarization is a slow but real process.

How the episode opens
We begin with the continuing conflict in Iran. Harvard professor and former IMF chief economist Ken Rogoff chronicled the U.S. dollar's rise and the beginning of its decline as a global currency in his latest book, "Our Dollar, Your Problem.
It turns out that it's not just oil and aluminum at risk in the Iran war. It also may be the status of the dollar. Ken, in your book, "Our Dollar, Your Problem," you talk about the position of the U.S.
dollar as declining gradually over time in relation to other currencies. We now have a conflict in Iran. Is that affecting that decline?
-I don't think there's any question that it will affect the decline. It could go either way. It depends on how it comes out.
If the U.S. comes out incredibly triumphant, there's peace in the Middle East, everyone, you know, looks to the United States to maintain peace, that's one outcome. Another outcome where it's viewed as a strategic defeat and China gains.
But, you know, it's a step. I don't think either way it's changing a dynamic that was going to happen anyway. There are things on the outside that it influences, so it's definitely going to help China accelerate getting other countries to use its currency, particularly for Chinese imports, for example, if China buys oil or if China buys anything.
It's going to help in that dimension. But it's also affecting global debt, because everybody sees a lot of need for military expending. The U.S.
is the biggest debtor in the world. We lose the most when global interest rates go up. So there are pressures from the outside coming from everybody trying to look for other options and pressures from the inside that we're, you know, running this big debt that is manageable if we wanted to, but there's not a lot of will to want to.
