The Petrodollar Didn't End in 2024. So What Actually Changed?
The 50-year U.S.–Saudi oil-for-dollars treaty that supposedly expired in June 2024 never quite existed. The system that did exist is more interesting — and it is changing in the flows, not in the headlines.
June 2024. Fifty years after the United States and Saudi Arabia deepened their economic relationship, the headlines arrived: The Petrodollar Agreement Has Expired.
The implication was enormous. For half a century Saudi Arabia had supposedly been required to sell its oil in U.S. dollars; now it could sell in yuan, or euros, and the foundations of the dollar system were cracking.
There was only one problem. The famous 50-year petrodollar treaty wasn't there. So we went looking for what was.
WE NOTICED
The story was almost too perfect.
The viral version runs: 1974 → 50-year agreement → June 2024 → agreement ends → dollar loses dominance. It spread across social media and a good deal of financial media in mid-June 2024. The trouble is the documentary record.
What actually happened in 1974.
On 8 June 1974 the United States and Saudi Arabia issued a joint statement establishing a Joint Commission on Economic Cooperation. Its stated focus was industrialisation, education, technology and agriculture — the Saudi historical record describes it that way. The implementation agreement, signed in February 1975, ran for five years. A U.S. Government Accountability Office report from March 1979 describes the arrangement and contains no clause about pricing oil in dollars. There is no expiry in June 2024 because there was no 50-year term; and 2024 fact-checks found no Saudi announcement terminating any oil-for-dollars pact. Sources: GAO 1979 report as cited by fact-checkers in 2024; Radio Free Asia and Nasdaq/TipRanks fact-checks, June–July 2024.
It was part of a much broader relationship after the 1973–74 oil shock. Saudi Arabia had suddenly accumulated enormous oil revenue and needed somewhere to put it. The United States had deep financial markets, Treasury securities, military capability, technology, companies — and the dominant currency. That created something more important than an oil-pricing contract. It created a financial ecosystem.
SO WE LOOKED
The petrodollar was never a currency.
A petrodollar is simply a dollar earned by selling oil. The term became shorthand for a loop:
Saudi Arabia earned dollars; the dollars were invested in dollar assets; the United States issued deep, liquid ones; the rest of the world needed dollars to trade. A reinforcing system. The quiet part was real: in 1974 the U.S. Treasury arranged for Saudi Arabia to buy Treasury securities outside the regular auctions, with the size of the holdings kept confidential for four decades — Bloomberg reported the arrangement in 2016, when the Treasury first disclosed a Saudi figure. That, not a treaty, is what “petrodollar recycling” meant. Source: Bloomberg, 2016, on the 1974 Treasury arrangement and the 2016 disclosure.
So what expired in 2024?
Nothing that priced oil. The dollar remains embedded in the oil trade. But that does not mean nothing is changing — and here the story gets interesting, because the power of the dollar never came from a sentence in a Saudi–American agreement. It comes from the network around it: energy → trade → banking → debt → Treasuries → collateral → foreign exchange → central-bank reserves → global capital markets. That is much harder to replace than an oil invoice.
But Saudi Arabia is changing.
The kingdom has deepened economic relationships with China, Russia, India and the wider BRICS group, said publicly that it is open to settling trade in other currencies, and in 2024 joined mBridge, the multi-central-bank digital settlement project. That does not mean Saudi Arabia is abandoning America. It means something subtler: Saudi Arabia has more options than it did in 1974. And options matter. The world of 1974 had one enormous financial system; today's is more multipolar — China vastly more important, Asian trade vastly larger, emerging markets holding far more capital, digital settlement changing the plumbing (see our piece on XRP and Ethereum). The dollar is not about to disappear. The system around it is becoming more contested.
HERE'S WHAT WE FOUND
Apex does not ask is the petrodollar dead? — too binary. It asks what the flows show. Here is what the flows we can measure show today:
Foreigners hold more Treasuries than ever — and a smaller share.
Federal debt held by foreign and international investors was about $9.3 trillion at the last reading, up roughly a third since the start of 2020. But the debt itself grew about two-thirds over the same period, so the foreign share fell — from around 30 % to under a quarter. The world is still buying; it is not keeping pace. That is exactly the kind of quiet shift the petrodollar debate should be about, and it has nothing to do with June 2024. Source: FRED FDHBFIN, GFDEBTN; live cell below.
Saudi holdings are small.
Saudi Arabia's own Treasury holdings run around $140 billion — about one and a half percent of the foreign total, and less than South Korea's. If Riyadh sold every bond it owns, the Treasury market would notice for a week. The recycling that mattered in 1974 is a rounding error in 2026; the buyers that matter now are Japan, the euro area, Britain, China and the world's money-market and stablecoin issuers. Source: U.S. Treasury TIC, table 5; live cell below.
The dollar has not weakened. It has strengthened.
If oil were quietly leaving the dollar, you would expect the fingerprint in the currency. As of mid-September 2026 the dollar index is up about 2 %, the 10-year yield is above 5 % and the real rate is at a twenty-year high — the United States is paying for its debt in real terms, not inflating it away. Our debt piece covers why that matters. Source: Yahoo DX-Y.NYB, FRED DGS10/T10YIE.
Oil decoupled from the dollar — in our own data.
This is the finding that surprised us. Apex measured the classic pattern — gold up, dollar down — on two years of daily data and found that Brent's response had vanished: −0.04 % across 103 episodes. On Apex's Asset Character map, Brent is the one instrument that detached from the rest of the board in 2026. Oil is trading on supply and the Strait of Hormuz, not on the currency. Whatever the petrodollar system once was, oil's price is no longer a dollar story day to day. Apex findings: the dollar pattern — FALLEN on the oil leg; Asset Character 2026.
The dollars that move on new rails are still dollars.
Stablecoin supply has grown from about $205 billion in January 2025 to about $312 billion, almost entirely dollar-pegged and backed largely by Treasury bills. The new settlement infrastructure that the de-dollarisation story fears is, so far, the dollar's newest distribution channel — and a new buyer of the debt. Source: DefiLlama.
BUT HERE'S THE CATCH
The dollar's real moat is not oil. The biggest mistake in the petrodollar debate is assuming oil creates the dollar. It is closer to the reverse: the dollar's existing financial dominance makes it convenient to price oil in dollars. Producers want a currency that is liquid, globally accepted, easy to hedge, easy to finance and easy to reinvest; the Treasury market and the foreign-exchange market provide that. Changing the currency on an oil contract is easy. Replacing the ecosystem around the currency is hard.
But the chain is worth testing, link by link. Suppose the share of energy settled in dollars gradually falls:
Every arrow carries a question mark on purpose. Less oil invoiced in dollars does not automatically mean less demand for dollars overall — a Chinese refiner paying in yuan still needs dollars for the ship, the insurance, the hedge and the loan. That distinction is critical, and it is why the change, if it comes, will not arrive as a headline. It will arrive as a gradual shift in reserve composition, settlement currencies, Treasury holdings, bilateral contracts and payment infrastructure. A flow story — exactly what Apex watches.
No. There was no switch to flip. There was a system — and systems don't expire on a date; they evolve. Until the flows confirm the story, it is still a story.
WHAT WE KNOW · WHAT WE DON'T
| What we know | No 50-year oil-for-dollars treaty existed; the 1974 instrument created an economic commission and the 1975 agreement ran five years · the real mechanism was Treasury recycling, disclosed in 2016 · foreign holdings of Treasuries are at a record in dollars and a falling share of the debt · Saudi holdings are about $140 billion · the dollar index is up in 2026 and real yields are at a 20-year high · Brent has decoupled from the dollar in Apex's data · digital dollars are the fastest-growing new buyer of Treasury bills. |
|---|---|
| What we don't know | What share of Saudi or Gulf crude is actually invoiced in non-dollar currencies — no reliable public series exists · whether the falling foreign share of Treasuries is choice or arithmetic (the debt simply grew faster) · whether mBridge and similar rails reach scale · how the dollar's role changes if U.S. real rates fall back toward zero. |
| What we think | The dollar's strength was never based on a Saudi agreement. It was built on liquidity, financial depth, trade, energy, debt and a global network of capital. The better question is not “did the petrodollar end” but “what happens when the world no longer needs the dollar quite as much as it once did” — and the answer will show up first in the flows. |
WHAT WE'RE WATCHING

WHAT WOULD CHANGE OUR MIND
What would actually convince us the system is changing — six flows, not one headline:
- Oil settlement: a major producer publishing a material, rising share of crude invoiced outside the dollar.
- Reserve allocation: central banks materially reducing the dollar's share of reserves for several consecutive years, not one.
- Treasury demand: foreign holdings falling in dollars, not just as a share — or a badly tailed auction with foreign bidders absent.
- Energy trade: large bilateral energy contracts settled in yuan, rupees or dirhams at scale, with the volumes disclosed.
- Financial infrastructure: mBridge or a successor carrying settlement volume that shows up in the numbers, not the press releases.
- Capital flows: the above producing measurable shifts in global allocation — the dollar index, the term premium, the gold–dollar relationship.
Until the data confirms the story, it's still a story. The live cells above are how we watch it.

QUESTIONS PEOPLE ASK
- Did the petrodollar agreement expire in June 2024?
- No. There was no 50-year treaty requiring Saudi Arabia to sell oil in dollars. The document dated 8 June 1974 was a joint statement creating a U.S.–Saudi Joint Commission on Economic Cooperation, and the implementation agreement signed in February 1975 ran for five years. A 1979 U.S. Government Accountability Office report describes no oil-pricing clause. Fact-checks in 2024 found no Saudi announcement ending any such pact.
- What was the 1974 U.S.–Saudi agreement actually about?
- Economic cooperation after the 1973–74 oil shock: industrialisation, education, technology and agriculture through a joint commission, alongside security cooperation. Separately, the U.S. Treasury arranged for Saudi Arabia to buy Treasury securities outside the regular auctions, an arrangement kept confidential for decades and reported by Bloomberg in 2016. That recycling of oil revenue into dollar assets is the real 'petrodollar system'.
- What is a petrodollar?
- Not a currency. A petrodollar is simply a U.S. dollar earned from selling oil. The word became shorthand for the loop that follows: oil sold for dollars, dollars invested in U.S. assets and Treasuries, Treasuries providing the world's deepest pool of safe dollar assets, and the rest of the world needing dollars to trade.
- Is Saudi Arabia selling oil in yuan?
- Saudi Arabia has said it is open to non-dollar settlement, has deepened trade with China, and joined the multi-central-bank digital settlement project mBridge in 2024. Apex has found no data showing a large share of Saudi crude actually invoiced in yuan; as of 2026 the dollar remains the currency of the oil trade. Openness to options is not the same as using them at scale.
- Why is oil priced in dollars?
- Because the dollar is liquid, globally accepted, easy to hedge, easy to finance and easy to reinvest — and because the U.S. Treasury market is the largest pool of safe assets on earth. The causality is closer to 'financial dominance makes oil pricing in dollars convenient' than 'oil pricing creates the dollar's dominance'.
- What would show the dollar system actually changing?
- Not an announcement. A gradual, measurable shift in six flows: oil settlement currencies, central-bank reserve composition, foreign demand for Treasuries, bilateral energy contracts, alternative settlement infrastructure gaining scale, and global capital allocation. Apex watches those; the live cells on this page track the ones it can measure.
