The throughline: how one 1970s decision set today's oil prices

Here’s a wild idea: the reason the U.S. dollar runs the world might come down to a few decisions made in the 1970s about oil. Not a battle, not an invention — a couple of handshakes and a currency call. Pull this thread and a huge amount of modern economics unravels in your hands. Let’s walk it.

1971Money stops being gold

For a long time, the dollar was backed by gold — in theory you could trade dollars for actual metal. On August 15, 1971, President Nixon ended that. The dollar became a “fiat” currency: backed not by gold but by trust in the U.S. government. Suddenly the question hanging over the whole system was — if it’s just trust, what keeps everyone wanting dollars?

1973The oil shock changes everything

Then came the 1973 oil crisis. Arab oil producers cut supply and prices quadrupled, hammering Western economies and showing exactly how much leverage oil exporters now had. The U.S. needed two things at once: to keep oil flowing, and to keep the world hooked on dollars. Saudi Arabia — sitting on enormous reserves — needed something too: security.

Oil and the dollar got married in the 1970s. Almost everything about modern money is downstream of that wedding.

THE DEALThe deal — and the myth

So they made an arrangement. The U.S. would provide military protection and support to Saudi Arabia; in return, the Saudis would keep selling oil priced in dollars and recycle their oil profits into U.S. assets, especially government debt. By 1975, effectively all of OPEC was pricing oil in dollars. This is the petrodollar system.

One honest correction, because this is where the internet gets it wrong: there was never a single secret treaty forcing the world to use dollars for oil. Dollar pricing was already common market practice. The closest real document was a 1974 U.S.-Saudi understanding — military support in exchange for the Saudis plowing oil revenue into U.S. Treasuries — and its details weren’t public until a 2016 Freedom of Information request revealed them. The myth is tidier than the truth; the truth is still huge.

THE PAYOFFWhy this still rules your life

Here’s the payoff. If everyone needs dollars to buy oil (and oil is the one thing every economy needs), then everyone needs to hold dollars — which creates constant global demand for U.S. currency and debt. That demand lets the U.S. borrow cheaply, run big deficits, and back its money with trust instead of gold. A lot of America’s financial superpower status sits on this foundation.

And it’s why you now hear talk of “de-dollarization” — countries experimenting with trading oil and goods in other currencies. Every time a major exporter prices a deal in something other than dollars, it’s a tiny chip at a system built in the 1970s. Whether it actually cracks is one of the defining money questions of our era.

The throughline: a currency decision and an oil deal, fifty years ago, still shape your rent, your country’s debt, and the price at the pump. That’s the whole Context Collapse thesis in one story — the present is just the past, still running in the background, quietly setting the prices nobody explains.
