The Loop Is Broken
How the war in Iran severs the financial architecture of American power—and what China is building in its place
There is a plan. No ministry has published it, no party congress has voted on it, and you will not find it written down anywhere. But if you watch where the cables go, where the factories are, and where the money flows, the shape of it becomes clear. China is building the infrastructure of a new world order, and the war in Iran just gave it a ten-year head start.
To understand why, you need to follow the money. Not the oil—the money.
The loop that ran the world
For fifty years, a single financial mechanism underwrote American power. It was elegant, self-reinforcing, and almost invisible to most of the people it affected.
Here’s how it worked. Gulf states sold their oil exclusively in dollars. The world needed that oil, so the world needed dollars. The dollars accumulated in sovereign wealth funds in Riyadh, Abu Dhabi, and Doha, and in turn those funds recycled the surplus into US Treasuries and American financial markets. With the system running at full capacity, Washington could borrow cheaply, run large deficits, and project military force across the globe—all of it quietly underwritten by the daily fact of oil changing hands in a single currency.
This was known as the petrodollar recycling system, and its origins could be found in an obscure deal, struck in 1974 between the Nixon administration and Saudi Arabia at a moment when America needed a new anchor for the dollar after deliberately abandoning the gold standard in 1971. Over time, petrodollar recycling ended up working better than almost anyone expected. By the time the shale revolution made America largely energy-independent, it had been running so long that most people had stopped seeing it as a system at all. It felt like gravity, an immutable law of the economic universe.
The question nobody asked was what happens when the planet underneath it shifts.
The system Washington is building to replace petrodollar recycling
The petrodollar was always going to fade, for various reasons that all became obvious over the past decade or so: US shale has reduced America’s own dependence on Gulf oil; the energy transition is slowly eroding the long-run value of hydrocarbon reserves; finally, world increasingly organised around data, AI, and compute infrastructure is going to need a different kind of scarce, dollar-denominated commodity to anchor global demand for American currency.
Washington’s answer to the predicted exhaustion of petrodollar recycling is compute: scarce, capital-intensive, dollar-denominated infrastructure whose settlement rails would do what oil revenues once did—an argument we developed in Barrels to Bytes last November, which was later re-quoted and further discussed by many—including John Naughton from The Observer in “Why Stablecoins “crypto for adults” have suddenly become a big deals.”
This is the through-line of American economic power that is easy to miss when you are focused on oil. The US did not just win the postwar era with military strength; it also won it by being the leader in the age of semiconductors, computing and networks and asserting control over the operating systems, the platforms, the protocols that became the invisible infrastructure of the global economy. From the 1990s onward, every serious economy ran on American software, and American software, by design, ultimately settled in dollars.
America’s bet for replacing petrodollar recycling follows the same logic, extended one layer further. AI is software. Crypto is software. Stablecoins are, at their core, the softwarisation of the dollar itself—programmable money that can move anywhere, settle instantly, and be embedded into any digital transaction on earth. A stablecoin issuer takes deposits, issues digital tokens pegged to the dollar, and reinvests the deposits in US Treasuries. The issuer earns the yield, the Treasury gets a buyer, the dollar gets a new payment rail, and every stablecoin in circulation becomes a small permanent bid for American government debt, thus cementing US hegemony for decades to come as we wrote in June last year. Stablecoins—or, as we call them, “cryptodollars”—are the new petrodollar.
The deeper question is what runs on top of those rails:
As AI agents proliferate—autonomous software systems that negotiate, transact, and settle on behalf of their users—the volume of machine-to-machine transactions will dwarf anything humans conduct today. Those agents need a settlement layer, and dollar-backed stablecoins are the natural candidate: programmable, instant, globally accessible, denominated in the currency that already anchors international trade.
Alongside the agent economy, the tokenisation of real-world assets is creating a second wave of structural demand—real estate, bonds, commodities, private credit, trillions of dollars of assets moving on-chain, each transaction requiring a settlement currency. If both run on dollar stablecoins collateralised by US Treasuries, the network effects compound in ways the petrodollar system could never have achieved. Oil was bought and sold by humans, in bulk, a finite number of times a day. Software agents transact continuously, at machine speed, at planetary scale.
The transition to this new world requires capital—vast amounts of it. The data centre buildout needed to anchor this new system runs into trillions of dollars globally, which is why, for the past three years, every American hyperscaler has been travelling to Riyadh, Abu Dhabi, and Doha with term sheets. Gulf sovereign wealth funds were to be the bridge: petrodollars recycled not into Treasury bonds directly, but into the compute infrastructure that would generate the next generation of dollar demand. Trump himself was pressing Gulf leaders for commitments running into hundreds of billions—American-technology-powered data centres built across the Gulf itself, turning old petrodollars into new cryptodollars. The system would renew itself. Stargate is a good example of the level of ambition that was laid ahead.
Following a grandiose visit, the first concrete proof of concept arrived in May 2025. MGX, an Abu Dhabi state-backed investment firm, used USD1—the dollar-pegged stablecoin launched by Trump’s own World Liberty Financial—to settle a $2 billion investment in Binance, the world’s largest crypto exchange. USD1 is backed one-to-one by US Treasuries. This particular transaction was, in miniature, exactly the loop the cryptodollar thesis describes: Gulf sovereign capital flowing through a dollar-denominated instrument collateralised by American government debt—the old petrodollar recycling mechanism, updated for the digital age. That the stablecoin happened to be the president’s own family venture added a layer of political controversy, but the monetary logic underneath it was precisely what Washington has been trying to build in the recent period.
Then the bombs fell.
Three things the war destroyed in a single night
The strike on Iran did not merely disrupt oil markets. It severed three structural elements of this plan at the same moment.
First, the Strait of Hormuz closed. Gulf producers could not safely ship their oil or collect their dollar receipts, and the automatic recycling of petrodollar liquidity into US financial markets—the mechanism that has quietly funded American deficits for five decades—stopped. The bridge capital for the cryptodollar transition, dependent on that same surplus, evaporated precisely when it was most needed.
Then, on the first Sunday of the war, Iranian drones struck three AWS facilities in the UAE and Bahrain, causing structural damage and extended outages. The message to every investment committee in the world was immediate and legible: a data centre in a war zone is a liability. The Gulf buildout—the physical foundation of the cryptodollar plan—became uninvestable overnight. Projects in Saudi Arabia, Qatar, and the UAE that had taken years to structure are now stranded, and the insurance market alone will ensure the capital does not come back quickly.
The third blow was slower but may prove the most durable. The war frightened the world about hydrocarbons as a foundation for anything. When supertanker cover gets pulled and a chokepoint carrying a fifth of the world’s traded oil comes under active threat, the case for domestic energy independence stops being a climate argument and becomes a simple matter of economic survival. The race to electrification lurched forward a decade in the space of a week. As Azeem Azhar and Hannah Petrovic write in their recent essay “The case for radical solar optimism”, the solar supercycle that makes this possible has been turning for fifty years and shows no sign of slowing.
We have seen this before. The 1973 oil shock hit Japan with particular violence—an island nation with no hydrocarbons, entirely dependent on Gulf imports. Tokyo’s response was to build its way out of the dependency with the Energy Efficiency Act. Japanese manufacturers spent the next decade engineering the world’s most fuel-efficient cars, the government poured investment into alternatives, and adversity became an industrial strategy. Japan’s auto industry became one of the most formidable export machines of the twentieth century. Every government watching the current crisis is running the same calculation now. The question is who builds the infrastructure that replaces fossil fuels.
China had not been waiting for a crisis or an opportunity. It has been building a parallel infrastructure for decades.
