The BRICS nations just settled another round of energy trades without using the dollar. Trump is threatening 100% tariffs on any country that moves away from dollar-denominated oil. The Federal Reserve is watching nervously.

Everyone is talking about dedollarization like it's a new idea.

Nobody is explaining why the dollar became the currency of oil in the first place.

That story starts in 1974, in a hotel in Riyadh, with Henry Kissinger and a secret agreement that has never been formally declassified.

On August 15, 1971, Richard Nixon went on television and announced that the United States would no longer exchange dollars for gold.

The Bretton Woods system, which had governed global finance since 1944 and had made the dollar the world's reserve currency by tying it to gold at $35 per ounce, was finished. The dollar was now backed by nothing.

For a brief moment, there was a real question: why would anyone want dollars?

Kissinger had the answer. And it had nothing to do with gold.

The problem with a floating dollar

Before 1971, the dollar's credibility was simple: you could exchange it for gold at a fixed rate. Every country holding dollar reserves knew exactly what they were holding.

After 1971, that guarantee was gone. The dollar was now a fiat currency, backed only by the full faith and credit of the U.S. government. Which is another way of saying it was backed by trust, military power, and the willingness of other nations to keep using it.

The risk was collapse of dollar demand. If countries stopped holding dollar reserves, they would sell their existing dollars, the currency would depreciate, and the United States would lose the extraordinary privilege it had enjoyed since 1944: the ability to print the world's reserve currency.

That privilege is not abstract. It means the U.S. can run trade deficits indefinitely, borrow at lower rates than any other country, and project financial power globally. Losing it would have been a civilizational economic event.

Kissinger's job was to make sure that didn't happen.

The deal

In 1974, the United States and Saudi Arabia entered into a series of agreements that have shaped the global financial system ever since.

The terms, reconstructed from declassified documents and reporting by Bloomberg in 2016, were straightforward:

Saudi Arabia would price its oil exclusively in U.S. dollars. Every barrel of Saudi oil sold to every country in the world would be invoiced, settled, and paid in dollars. Saudi Arabia would also invest a substantial portion of its oil revenues into U.S. Treasury bonds, recycling petrodollars back into American debt.

In exchange, the United States would provide military protection to the Saudi regime. Arms sales. Security guarantees. A permanent American military presence in the Gulf.

The agreement was not a formal treaty. It was never submitted to Congress. It was never publicly announced. It was a bilateral arrangement between two governments, with no democratic oversight on either side.

One deal. And it solved the dollar's problem permanently.

Why it worked mechanically

The genius of the petrodollar system is that it created structural, unavoidable demand for dollars from every country on earth.

Here is the mechanism:

Japan needs oil. Japan buys its oil from Saudi Arabia. Saudi Arabia only accepts dollars. Japan must therefore acquire dollars before it can purchase energy. Japan goes to the currency markets, sells yen, buys dollars, and uses those dollars to pay for oil.

Germany needs oil. Same process. China needs oil. Same process. India, Brazil, South Korea, every industrialized economy on earth needs oil, and every barrel is priced in dollars.

This means every country in the world must hold dollar reserves simply to participate in the global energy market. Not because they trust the dollar. Not because they want American assets. Because they have no choice.

The demand for dollars is not based on confidence in American economic management. It is based on the physical requirement to buy energy.

The United States prints dollars. The world needs dollars to buy oil. The world sends real goods, real resources, and real labor to the United States in exchange for those dollars. The U.S. receives a permanent structural subsidy from every energy-importing nation on the planet.

Economists call this the "exorbitant privilege." It is not a figure of speech.

What it costs everyone else

The petrodollar system has direct financial consequences for every country that is not the United States.

Developing nations are hit hardest. A country in Sub-Saharan Africa that needs to import oil must first earn dollars, typically by exporting commodities or manufactured goods to Western markets. If the dollar strengthens, their energy costs rise in local currency terms even if the oil price in dollars stays flat. Their central banks must hold dollar reserves as a buffer against energy price volatility.

Dollar reserve accumulation means buying U.S. Treasury bonds. Which means lending money to the United States at relatively low interest rates. Which means the United States borrows cheaply, partly on the backs of developing economies that have no alternative.

The 1997 Asian financial crisis, the 1998 Russian default, the recurring currency crises in Latin America throughout the 1990s and 2000s: all of them were amplified by dollar dependency. When the Fed raises rates, dollar-denominated debt becomes more expensive for every developing nation simultaneously. Their currencies weaken. Their import costs rise. Their debt servicing costs increase.

The Fed makes monetary policy decisions based on the American domestic economy. The consequences of those decisions are distributed globally.

The petrodollar deal was not purely beneficial for Saudi Arabia, and understanding why the Saudis accepted it explains a great deal about how the system has been maintained.

Saudi Arabia in 1974 was an absolute monarchy with enormous oil wealth and very limited military capacity. The 1973 oil embargo had demonstrated that the kingdom could exercise economic power, but it had also exposed its vulnerability to potential retaliation.

American military protection was not a minor consideration. The U.S. security umbrella covered the Saudi regime against external threats, and implicitly against internal ones. American arms sales provided the military hardware. American military advisors helped train Saudi forces. The Fifth Fleet in Bahrain provided a permanent deterrent in the Gulf.

In exchange for pricing oil in dollars and recycling petrodollar revenues into Treasury bonds, Saudi Arabia received something that money cannot directly buy: regime survival insurance.

That arrangement has held for 50 years. Every American president, regardless of stated foreign policy, has maintained the core commitment. The U.S. military presence in the Gulf is not humanitarian. It is the enforcement mechanism for a financial arrangement.

What is actually happening with dedollarization

The BRICS nations, Saudi Arabia's recent discussions about yuan-denominated oil sales to China, and the general trend toward non-dollar settlement in energy trades are real. But the scale needs context.

The dollar currently accounts for approximately 58% of global foreign exchange reserves, down from 71% in 2000. That is a meaningful decline over 25 years. It is not a collapse.

What is actually changing: the marginal trades are moving. China and Russia now settle a substantial portion of their bilateral energy trade in yuan and rubles. Saudi Arabia completed its first yuan-denominated LNG transaction with China in 2023. The BRICS payment infrastructure is under active development.

What is not changing quickly: the core infrastructure of global oil markets. Futures contracts on the major exchanges are denominated in dollars. Most oil-producing nations still price exports primarily in dollars. The dollar's share of global trade finance remains dominant.

The petrodollar system is not ending. It is being slowly, partially, contested at the margins by countries that have concluded that dollar dependency is a geopolitical liability. That conclusion was clarified considerably when the U.S. and G7 froze $300 billion in Russian reserves in 2022. Every central bank that isn't in the Western alliance looked at that and asked the same question: what stops this from happening to us?

The gold buying documented in Issue #003 is part of the answer. The yuan oil trades are part of the answer. The BRICS payment system is part of the answer.

None of them are, yet, the complete answer.

What this means for your money

The petrodollar system has three direct implications for how you should think about your portfolio.

Dollar strength is structurally supported but structurally contested. The dollar benefits from 50 years of embedded infrastructure, treaty relationships, and financial market convention. It also faces a slow, deliberate campaign by a coalition of countries that represent a growing share of global GDP. This is not a binary outcome. It is a decades-long transition with significant volatility along the way.

Energy majors benefit from the system regardless of dollar direction. The companies that extract, refine, and distribute oil operate within the petrodollar framework. Whether the dollar strengthens or weakens, oil demand continues and the majors capture margins at every stage of the supply chain.

Gold and real assets serve as hedges against dollar system instability. This is not speculative. It is what sovereign wealth funds, central banks, and institutional investors are explicitly doing in response to the geopolitical fragmentation of the dollar system. The retail investor version of this logic is straightforward: if the institutions that built the system are diversifying away from it, the information asymmetry is gone.

The petrodollar was not a natural feature of markets. It was a political decision made by two governments in a hotel in 1974. Political decisions can be unmade. The process of unmaking this one is already underway.

Knowing that is not a prediction. It is a framework for understanding what you are watching.

One number to leave you with

The United States ran a current account deficit of approximately $1.1 trillion in 2023.

That means the U.S. imported $1.1 trillion more in goods and services than it exported. It covered that deficit by issuing dollar-denominated assets, primarily Treasury bonds, that the rest of the world is structurally required to hold.

A country that runs a $1.1 trillion annual deficit without a reserve currency faces a currency crisis. Argentina knows how this ends. So does Turkey.

The United States has run continuous current account deficits since 1982. It has not faced a currency crisis.

That is not good economic management. That is the petrodollar.

And it was decided in a hotel room, in secret, by two men that nobody elected to make that decision.
