Why oil priced in dollars gives the US structural asymmetry in global finance

September 1, 2026 · 10 min

Eliza Ward & Brian Reed

Oil priced in dollars forces every oil-importing nation to hold dollar reserves, recycling surpluses into U.S. Treasuries — a loop engineered in a 1974 U.S.-Saudi deal that gives the U.S. structural borrowing advantages economists call 'exorbitant privilege,' regardless of American economic performance.

The petrodollar system describes the structural arrangement by which globally traded oil is priced and settled in U.S. dollars, creating persistent transactional and reserve demand for U.S. currency and Treasury debt.

About this episode

In 1971, Nixon closed the gold window and the dollar needed a new anchor. What replaced gold wasn't another metal or a new treaty — it was oil, and a quiet arrangement struck with Saudi Arabia in 1974. This episode traces how that deal worked, why it didn't need to be law to function like one, and what it actually costs the countries that have no way out of it. The core mechanism is worth understanding: oil priced in dollars means every importing nation has to hold dollars before it can buy energy. Central banks stockpile them as buffers. Oil exporters recycle the surplus into U.S. Treasury securities. The loop is self-reinforcing and largely indifferent to how the U.S. economy is actually performing. Economists call the result 'exorbitant privilege' — the U.S. borrows cheap and runs deficits that would destabilize any other country, because structural demand absorbs them. But the privilege has a second side. When the Fed tightens to fight American inflation, the dollar strengthens and commodity prices shift — oil, food, metals, all priced in dollars — and that transmits across every importing economy whether they wanted tighter money or not. The episode also works through what the 2022 Russian reserve freeze changed: not the existence of an exit from dollar dependence, but the political calculus around staying in. The Atlantic Council says the dollar is secure near and medium term. Franklin Templeton says no credible alternative exists. Both are probably right on the structural facts. Neither can tell you when 'glacial' tips into something faster — and by the logic of the episode itself, you won't know until it already has.

Frequently asked

What is the petrodollar system and how does it work?

The petrodollar system, formalized in a 1974 U.S.-Saudi Arabia agreement, prices global oil in dollars. Oil-importing nations must hold dollar reserves to buy energy, while exporters like Saudi Arabia recycle surplus dollars into U.S. Treasury securities. This creates self-reinforcing global demand for U.S. currency and debt.

Why does the U.S. get to run large deficits without a currency crisis?

The petrodollar system generates structural demand for U.S. dollars and Treasury securities from every oil-importing and oil-exporting nation. Economists call this 'exorbitant privilege' — the demand is mechanical, not earned, so the U.S. can sustain current account and fiscal deficits that would destabilize any other economy.

How does the U.S. Federal Reserve affect other countries through the petrodollar?

When the U.S. Federal Reserve raises interest rates, the dollar strengthens and commodity prices — oil, food, metals, all dollar-denominated — shift globally. Countries with dollar-denominated debt face higher repayment costs immediately, even though they had no vote in the Fed's decision. This is the mechanism by which the U.S. exports its monetary policy.

Did the 2022 freezing of Russia's dollar reserves threaten the petrodollar system?

The U.S. and allies froze approximately $300 billion in Russian central bank reserves in 2022 over a weekend without a court ruling. The move proved the dollar system's coercive power but simultaneously gave every other central bank a reason to question whether their own reserves could be similarly frozen, accelerating interest in dollar alternatives.

Could the petroyuan or BRICS alternatives replace the petrodollar?

As of 2024, the Atlantic Council's Dollar Dominance Monitor found the dollar secure near and medium term, and analysts including Franklin Templeton cited U.S. market depth, rule of law, and convertibility as barriers no alternative can quickly replicate. However, the 2022 reserve freeze gave nations a political — not just economic — incentive to reduce dollar dependence.

Eliza Ward: Brian, quick question before we get going — do you know offhand what year the U.S. stopped backing dollars with gold?

Brian Reed: 1971, Nixon — yeah. Why, did someone actually get that wrong in the wild?

Eliza Ward: No, I just — someone asked me what came *after* that, like what replaced gold, and I said 'oil' and they looked at me like I was describing a conspiracy. Which made me think we should actually pull this apart.

Brian Reed: Because it does sound a little insane when you say it out loud.

Eliza Ward: It does. But it's real. Bretton Woods collapses, dollar destabilizes, and the U.S. negotiates — specifically with Saudi Arabia, 1974 — this arrangement where oil gets priced in dollars, the Saudis and OPEC recycle their surpluses into U.S. Treasury securities, and in exchange the U.S. provides military protection and market access.

Brian Reed: And the thing that gets me is — that's not a law anywhere.

Eliza Ward: No treaty, no court, nothing. The 1973 embargo — King Faisal, OPEC cutting supply, Western economies reeling — that's what forced the U.S. to engineer this fast. And what they built wasn't legal architecture. It was a structural incentive so overwhelming that every oil-importing nation behaved as if it were law.

Brian Reed: So the whole system rests on the fact that no workable alternative existed. Which is a very different thing than the system being permanent.

Eliza Ward: Right — but that's actually where it gets more concrete. Because 'no alternative existed' is kind of abstract until you picture a specific finance minister.

Brian Reed: Walk me through it.

Eliza Ward: Say you're running Brazil's central bank. Your country imports oil from Saudi Arabia. Before you can write a single check — not one — you need dollars. Not reais. Not anything else. Dollars. So you're always sitting on a dollar cushion, not because you love the dollar, just because energy doesn't wait.

Brian Reed: And Saudi Arabia ends up holding a ton of dollars it needs to do something with — so, wait, it just... parks them in U.S. Treasuries? That's the move?

Eliza Ward: That's the move. They're the safest dollar-denominated asset available. So the loop is — importers need dollars to buy oil, central banks stockpile them as buffers, exporters recycle the surplus into Treasury securities. And that loop runs whether the U.S. economy is doing well or not. It's kind of — I mean, it's almost mechanical at that point.

Brian Reed: Which means the U.S. gets to borrow cheap and run deficits because this engine is just — it doesn't stop. Economists actually call that 'exorbitant privilege.' The demand is structural, not earned.

Eliza Ward: And that's what the 1974 accord actually built. Not a treaty — a perpetual demand machine for U.S. currency and debt. OPEC's embargo forced the crisis, the U.S. engineered the fix, and the fix turned out to be self-reinforcing in a way nobody — actually, no, some people saw it, but not how durable it would be.

Brian Reed: The part that doesn't sit right for me — Brazil's finance minister isn't choosing this. She's just doing the only thing that works. Which means the whole machine runs on the absence of an exit, not on anyone actually wanting to be in it.

Eliza Ward: And that absence of exit — that's actually where it gets expensive for everyone who isn't the U.S. Because the machine running doesn't mean it runs neutrally. When the Fed raises interest rates to kill American inflation, every government with dollar-denominated debt just got a bigger bill. Kenya, Argentina, whoever — they had no vote in that decision.

Brian Reed: Wait, so the U.S. is exporting its monetary policy?

Eliza Ward: Literally. The Fed tightens, dollar strengthens, commodity prices shift — oil, food, metals, all priced in dollars — and that transmits across every importing economy whether they wanted tighter money or not.

Brian Reed: So it's not just that the U.S. borrows cheap through petrodollar recycling into Treasuries — it's that the U.S. also gets to run persistent current account deficits, fiscal deficits, deficits that would crater any other economy, because the structural demand absorbs them. And meanwhile a rate hike in Washington is a debt crisis in Nairobi. That's — I mean, that's the exorbitant privilege with the second half of the sentence attached.

Eliza Ward: Which is — yeah, that's exactly the framing China, Russia, India, the whole BRICS bloc uses. Brazil, South Africa, later members — they're not building alternative frameworks because they have something better ready. They're building them because the dependency is visibly inequitable and every Fed cycle makes it more so.

Brian Reed: Right — but is it inequitable enough to actually pay the exit cost? Because switching away from dollar infrastructure, that's not free. Franklin Templeton's argument, basically, is that the depth of U.S. markets, the rule of law, the convertibility — you can't replicate that fast. So even if the system is a tax, it might be a cheaper tax than the alternative.

Eliza Ward: That's the question I can't resolve from the structural side alone. And — wait, actually this is where something happened in 2022 that breaks the clean version of that argument open in a way I don't think we've fully accounted for yet.

Brian Reed: The reserve freeze.

Eliza Ward: Three hundred billion dollars, frozen. And that's the part that comes next — because that single event somehow proves the system is powerful and proves it's self-undermining at the same time, and I genuinely don't know how you hold both of those conclusions.

Brian Reed: Three hundred billion. Frozen over a weekend. Not after a court ruling, not after a sanctions hearing — a geopolitical decision, done. And the thing that breaks me a little is: central banks hold reserves because they're supposed to be untouchable. That's the whole point. You hold them so you have a floor. And the U.S. just — pulled the floor.

Eliza Ward: And it proved the system works. That's what made it so — wait, it's almost paradoxical. The coercive power was real. Russia couldn't access $300 billion of its own reserves.

Brian Reed: But every finance minister watching that just got handed a question they can't un-ask.

Eliza Ward: Which is: are mine next?

Brian Reed: Right. And — so Deutsche Bank is out here predicting the rise of the petroyuan, BRICS nations are building workarounds, and then the Atlantic Council's June 2024 Dollar Dominance Monitor comes out and says — the dollar is secure, near and medium term. Franklin Templeton says no credible alternative exists, deep markets, rule of law, convertibility, can't replicate it fast. They're all probably correct. That's the part I can't — I mean, how do you hold all of that at once?

Eliza Ward: Because they're answering different questions. Atlantic Council is asking: is there a functional replacement today? No. Deutsche Bank is asking: what happens to dollar pricing if petroyuan invoicing expands in, say, Iran's oil trade? Different question.

Brian Reed: So the freeze didn't create an exit — it created the motivation to find one. And India, Saudi Arabia, they didn't abandon the dollar after 2022. They stayed in. But they're also — they know now. The cost of dependence isn't abstract anymore.

Eliza Ward: That's the thing the research can't settle. The U.S. demonstrated maximum veto power and maximum reason to exit in the same move. Those aren't separable.

Brian Reed: So the signal isn't whether an alternative exists — it's whether the cost of staying eventually outweighs the cost of a worse alternative. And nobody can put a number on that threshold.

Eliza Ward: And that's — I mean, this keeps hitting me and I can't get past it. It doesn't require a petroyuan that's actually better. It doesn't require BRICS building something that beats U.S. market depth or rule of law or convertibility. It just requires enough finance ministers deciding that the sanctions risk is a cost they'd rather pay than absorb. That's not an economic calculation. That's a political one. And political calculations shift faster than market infrastructure.

Brian Reed: Which is — yeah, and that's what I genuinely can't answer. The Atlantic Council says secure, near and medium term. Franklin Templeton says no credible alternative. Both probably right on the structural facts. But neither of them can tell you when 'glacial' tips into something faster. And by definition, you won't know until it already has.

Eliza Ward: No verdict on timing. That's honest.

Brian Reed: The structural barriers protecting the dollar are — actually, wait — they're the same ones that could make a transition rapid when it comes. Because if you wait until the alternative is good enough, you've waited until the move happens fast. There's no slow version of that exit.

Eliza Ward: I don't think I can resolve that. Genuinely. I keep trying to find the signal — is it petroyuan invoicing, is it another freeze, is it just bilateral trades accumulating quietly outside the dollar — and the honest answer is I don't know which one tips it, or when.

Brian Reed: That feels like the right place to stop. Not because we figured it out — because we didn't, and that's actually the point. Thanks for thinking through it with me.
