The petrodollar system, the arrangement that has underpinned global oil trade and the U.S. dollar’s reserve currency status for half a century, is showing clear signs of fracture. On April 28th, the United Arab Emirates — a founding OPEC member since 1967 — announced it would leave the oil cartel effective May 1st. The energy minister said the move would make it easier for the UAE to meet changing demand. But the timing and context suggest a far more consequential motive: the UAE is signaling that it may stop pricing its oil exclusively in dollars.

Just days before the OPEC exit, the UAE issued a warning, according to reports: if the country runs low on dollars amid the ongoing Iran war, it may be forced to price oil in yuan or other currencies. The implicit threat is massive. The Gulf Cooperation Council collectively holds over $2 trillion in U.S. assets. A coordinated sell-off could destabilize American markets. Treasury Secretary Scott Bessent acknowledged as much when he told the Senate that swap lines — essentially emergency dollar loans — were needed to “prevent the disorderly sale of US assets.” The United States, in other words, blinked.

This isn’t just an oil story. It’s a story about power, leverage, and the slow unwinding of the financial architecture built after the U.S. abandoned the gold standard in 1971.

How we got here: the petrodollar deal that was never supposed to be public

In 1971, President Richard Nixon closed the gold window, ending the dollar’s direct convertibility into gold. The U.S. dollar became pure fiat — paper backed only by trust. The problem was immediate: why would oil-producing nations sell a finite resource (oil) for an infinitely printable currency? Only a fool, as the analyst Andre Jick puts it in a widely circulated video, would trade something real for something that isn’t.

Secretary of State Henry Kissinger flew to Saudi Arabia in 1974. The deal that emerged was never officially announced until a 2016 Bloomberg Freedom of Information request revealed its terms. Saudi Arabia agreed to price its oil exclusively in dollars. Those dollars would be recycled into U.S. Treasury bonds — essentially lending the money back to America. In exchange, the U.S. provided military protection and weapons. This arrangement, now known as the petrodollar system, created permanent structural demand for the dollar. Every country that needed oil — which is every country — first had to acquire dollars to buy it. OPEC became the enforcement arm, managing supply to keep the dollar-denominated pricing intact.

That deal expired in June 2024. Saudi Arabia let it lapse. The financial media initially dismissed the story as misinformation; it turned out to be true. And then the Iran war began on February 28, 2025, creating an economic crisis for the same Gulf states the petrodollar system was built to protect.

The Iran war breaks the economic model of the Gulf states

The Strait of Hormuz handles about 20% of the world’s daily oil and gas supply. Ships from Saudi Arabia, the UAE, Kuwait, Qatar, and Iraq all pass through it. When Iran closed the strait, the entire economic model of the Gulf states stopped working.

Consider Saudi Arabia. Before the war, it needed oil at roughly $100 per barrel to cover basic government spending, including imports and social programs. The country exported close to 7 million barrels per day to pay for it. With the strait closed and oil exports slashed, one economist calculated that Saudi Arabia would now need oil at $170 per barrel to generate the same revenue. The paper price of oil, suppressed by futures market manipulation, is not anywhere near that level. Saudi Arabia is bleeding money: external borrowing has hit over $100 billion in the trailing four quarters, a level never before seen in its history.

Worse, Gulf currencies are pegged to the U.S. dollar. Maintaining that peg requires a huge buffer of dollar reserves. Those reserves are draining fast. And the war that caused all this was started by their ally, the United States. As Jick summarizes: “What do you do when your ally starts a war in your backyard, cuts off your income, drains your dollar reserves, and manipulates the paper price of oil? You make a phone call and say, ‘We need more dollars, and we own a lot of your assets. Want to give us some money? Call it a swap line.’”

China plays the long game

The UAE didn’t just call Washington. It first locked in a relationship with Beijing. On April 14th, the UAE crown prince met personally with Xi Jinping in China. The next day, the two countries signed 24 trade and investment deals, pushing bilateral trade over $100 billion. On April 19th, the Wall Street Journal published the yuan threat. On April 22nd, Scott Bessent agreed to the swap line before the Senate. On April 28th, the UAE left OPEC.

The sequence is clear: the UAE used the China card to extract concessions from the U.S. Treasury. As President Trump told CNBC, calling the UAE a "good ally," the country would likely get the swap line it wanted. The next day, Bessent endorsed it.

China has been quietly building the alternative infrastructure for years. Yuan clearing banks now operate in London, Dubai, Singapore, Hong Kong, and Switzerland. BHP, one of the world’s largest mining companies, signed a deal shifting commodity sales to yuan-based pricing with a Chinese state buyer. Iran has been selling oil to China in yuan for years. The U.S. dollar’s share of global foreign exchange reserves has fallen from about 72% in 2001 to the low 50s today. That’s still the single largest share, but it’s hardly a monopoly.

What’s replacing dollar reserves? Gold. Central banks around the world — the most conservative financial institutions on the planet — have been buying gold at the fastest pace in 50 years. They are choosing to hold gold over U.S. government debt because trust in Treasuries has eroded. The proximate cause: in 2022, the U.S. froze Russia’s foreign exchange reserves, effectively seizing $30 billion in assets. Every central bank took note. If the U.S. can do that to a nuclear-armed rival, it can do it to anyone. Gold cannot be frozen.

The real leverage: rare earths and missile stockpiles

The petrodollar story is often told in financial terms, but the deeper leverage is physical. The U.S. military depends on Chinese rare earth minerals and tungsten for missile interceptors, fighter jets, and precision-guided weapons. China controls roughly 60% of global rare earth mining and an even larger share of processing. As Luke Groman, an economist cited by Jick, puts it: “The US has essentially been telling China, ‘I need you to speed up the rate at which you’re making missiles for me to point at you. And by the way, buy our bonds to finance the missiles that you’re making so we can point them at you.’”

CNN has reported that the U.S. military has significantly depleted its stockpile of key missiles during the Iran war, and that it cannot replace those stockpiles for another five to six years at minimum. The rate of consumption exceeds the rate of production. You cannot fight a war with paper assets. For 50 years, the United States operated as if printing dollars and recycling them through financial markets was a substitute for actually making things. China made things. It bought copper mines, built ports, invested in rare earth processing, and built its own payment system alongside SWIFT. China waited. Now it’s winning.

What it means for the dollar, gold, and your portfolio

If the petrodollar system is truly breaking down, the consequences are profound. The dollar’s reserve status has allowed the U.S. to borrow at lower interest rates than any other country, run persistent trade deficits, and finance wars without immediate fiscal pain. That privilege is now being negotiated in real time.

For investors, the key signals are clear. Central banks are buying gold, not Treasuries. The dollar’s share of reserves is declining. Alternative payment systems are being built. And the UAE’s threat to price oil in yuan is the first time a major OPEC member has explicitly linked its participation in the dollar system to a specific geopolitical conflict. The UAE didn’t just leave OPEC; it showed that a Gulf state holds enough American assets that a disorderly sale would be viewed as a threat by the U.S. Treasury itself.

Gas prices at the pump are already at record highs. The paper price of a barrel of oil has gone above $100. If the Strait of Hormuz remains closed and the Iran war continues, oil will go higher still. And if more Gulf states follow the UAE’s lead in diversifying away from dollar pricing, the dollar could face a structural decline that no swap line can reverse.

The petrodollar system was a deal held together by implicit threats — military protection in exchange for dollar pricing. That deal is now being renegotiated under duress. The UAE demonstrated that the implicit threat can run both ways. The real question is which side blinks first, and what new system emerges from the negotiation.
