The petrodollar: oil priced in dollars since the 1974 US–Saudi deal

1974· Concept

Fact, law or dataA rule, statute, definition or measured number.

The system of pricing oil in dollars and recycling oil exporters' dollar earnings into US assets.

See it on the Money & Finance map →

How it works

Oil prices quadrupled in 1973–74. In 1974 Treasury Secretary William Simon reached an informal deal with Saudi Arabia: the kingdom would quietly invest its surpluses in US Treasuries, in return for US military and economic cooperation. Saudi Arabia and OPEC kept pricing oil in dollars. OPEC's huge dollar surpluses were also deposited in Western banks, which lent them to Latin American governments, a key root of the 1982 debt crisis. No formal treaty existed.

Why it matters

It created steady demand for dollars and Treasuries just after the gold link ended, helping the dollar stay central.

Facts, rules and data

Declassified Treasury cables reported by Bloomberg in 2016, and Treasury's first disclosure of Saudi holdings, about $117 billion, that same year.

Debates and risks

Historians debate whether the 1974 arrangement built dollar dominance or merely reflected it, since oil was already largely priced in dollars.

▸The petrodollar: oil priced in dollars since the 1974 US–Saudi deal reinforced The US dollar as the world's reserve currencyMainstream view

The connection

Oil is the world's most-traded commodity. Pricing it in dollars means importers need dollars, and exporters with surpluses park them in dollar assets, mainly Treasuries and US bank deposits. This recycling created steady global demand for dollars and Treasuries just as the gold link ended, reinforcing the dollar's central role.

When and why

From the mid-1970s, led by Saudi Arabia and Gulf exporters, whose Treasury holdings grew through the 1970s and 1980s.

How solid is the link?

Treasury's TIC data on oil exporters' holdings; Saudi Arabia's holdings, kept secret until 2016, were then about $117 billion.

Debates and risks

Economists debate how much oil pricing still matters: some oil now trades in yuan, rubles or rupees, yet the dollar's reserve share has fallen only gradually.

▸The petrodollar: oil priced in dollars since the 1974 US–Saudi deal propped up the dollar after Nixon shock: the dollar leaves gold (1971)Mainstream view

The connection

After the gold link broke in 1971 and oil prices quadrupled in 1973–74, the US needed new reasons for the world to hold dollars. Treasury Secretary William Simon's 1974 talks with Saudi Arabia arranged for the kingdom to buy Treasuries through special confidential channels, in return for US military and economic support. Oil money flowing back steadied the floating dollar.

When and why

Simon's July 1974 trip to Saudi Arabia, after a June 1974 joint economic commission; Saudi purchases were made outside regular Treasury auctions.

How solid is the link?

Declassified Treasury cables obtained by Bloomberg in 2016 describe the deal; until then Saudi holdings were reported only within a broader oil-exporter total.

Debates and risks

Viral 2024 claims that a 50-year 'petrodollar treaty' had expired were false; no treaty existed. How decisive the deal was versus market forces is debated.

▸The petrodollar: oil priced in dollars since the 1974 US–Saudi deal steered Saudi oil money into US Treasury securitiesFact, law or data

The connection

In 1974, Treasury Secretary William Simon agreed with Saudi Arabia that the kingdom could buy Treasuries through special 'add-on' arrangements outside normal auctions, with its holdings kept confidential. Saudi oil surpluses, earned in dollars, flowed into US government debt rather than gold or other currencies, helping fund US deficits after the oil shock.

When and why

Negotiated in July 1974; Saudi holdings were hidden inside an 'oil exporters' group in Treasury data until 2016.

How we know

Declassified cables obtained by Bloomberg in 2016, after which Treasury first disclosed Saudi holdings, about $117 billion.

Debates and risks

How large Saudi holdings really are today is unclear, since some may sit with custodians in London or elsewhere outside the reported figure.

▸Petrodollar recycling: oil surpluses lent back to the world is the flip side of The petrodollar: oil priced in dollars since the 1974 US–Saudi dealFact, law or data

The connection

Pricing oil in dollars meant exporters earned dollars; recycling is what they did with them. Gulf states bought Treasuries and deposited surpluses with banks, which lent them on. That return flow is what made the petrodollar support the dollar rather than drain it.

When and why

From 1974, centered on Saudi Arabia, the US Treasury and banks in New York and London.

How we know

Treasury holdings data, BIS banking statistics and declassified 1974 Treasury cables.

Debates and risks

Whether recycling still matters much now that US shale has made America a net petroleum exporter.

▸The false 2024 claim that the petrodollar deal 'expired' wrongly claims a 50-year term for The petrodollar: oil priced in dollars since the 1974 US–Saudi dealFact, law or data

The connection

The myth borrowed the petrodollar's real 1974 origin and invented a 50-year expiry. The real arrangement was never a treaty with a term; it was an informal investment deal plus OPEC's long habit of pricing oil in dollars, which continued unchanged after June 2024.

When and why

Spread online in early June 2024, around the 50th anniversary of the 1974 joint statement.

How we know

The 1974 documents contain no expiry or currency clause, and Saudi oil kept trading in dollars.

Debates and risks

Whether the US–Saudi security relationship, not any document, is what still underpins dollar oil pricing.

▸The petroyuan: pricing and paying for oil in yuan challenges The petrodollar: oil priced in dollars since the 1974 US–Saudi dealExperts disagree

The connection

The petrodollar rests on oil being priced and paid in dollars. The petroyuan offers China's currency instead: yuan futures in Shanghai and yuan payments from China to Russia and Iran. So far it chips at the edges; Brent and WTI remain the benchmarks, and most oil still sells for dollars.

When and why

China since 2018; scaled up with Russia after 2022.

How solid is the link?

Trade and exchange data show growing yuan use, but no complete measure of oil-trade currency shares exists.

Debates and risks

Experts disagree on whether this is a slow structural shift or a sanctions workaround that would fade if sanctions eased.
