Is the Petrodollar Era Ending?

In 2023, a Chinese state energy company purchased liquefied natural gas from the UAE, not in dollars but in yuan. The transaction was small. The signal it sent was not. It was one of the first times a Gulf producer settled an energy deal in China’s currency through the Shanghai Petroleum and Natural Gas Exchange, bypassing the dollar-clearing infrastructure that has anchored global oil markets since the Nixon era.

​

The deal did not mark the sudden end of an era. But it unfolded at a moment of mounting pressure on what until recently had seemed an immovable system: the petrodollar.

​

How Oil Cemented Dollar Power

The petrodollar system emerged from a geopolitical arrangement struck in the early 1970s, after President Nixon suspended the dollar’s convertibility into gold and formalised the collapse of the Bretton Woods system. The United States needed a new anchor for international dollar demand. It found one in oil.

​

Beginning in 1973, the United States reached strategic agreements with major oil producers, most critically Saudi Arabia, under which crude oil would be priced and traded in U.S. dollars. Other OPEC members soon followed. The consequences were far-reaching. Countries needed dollars in order to buy oil. Oil producers accumulated those dollars and reinvested them in U.S. Treasury securities. This deepened American capital markets and kept borrowing costs low, allowing the United States to run persistent trade deficits without triggering the balance-of-payments crises that plagued other economies.

​

In return, Saudi Arabia received security guarantees and American military support. The structural benefits to the United States were immense. Beyond economics, dollar centrality enhanced geopolitical leverage, as global payments and financial flows passed through dollar-based infrastructure.

​

Why the Old Order Is Being Tested

Three forces are now testing the durability of this system. The first is sanctions. When Western governments froze approximately $300 billion in Russian foreign exchange reserves in 2022, the message to every other country holding dollar assets was clear: access to those reserves depends on political decisions made in Washington. For countries that fear becoming potential targets, or simply wish to reduce that risk, it was a clarifying moment.

​

The second is the shifting geography of energy production itself. The United States, transformed by the shale revolution, is now the world's largest oil producer and a net exporter. Its strategic dependence on Middle Eastern oil has diminished sharply. China, by contrast, has become Saudi Arabia's single largest customer, absorbing more than one-fifth of the kingdom's exports. Trade flows are reshaping political alignments.

​

The third force is structural. Oil itself is less central to the global economy than it was in 1973. Services, technology, and digital finance account for a growing share of global value creation. The commodity that once anchored an entire monetary order no longer occupies the same commanding position. The petrodollar system was built for an industrial world that is steadily evolving.

​

Building an Alternative to the Dollar

China has pursued renminbi internationalisation strategically. Bilateral currency swap lines now extend to dozens of countries. The Cross-Border Interbank Payment System offers an alternative to the dollar-based SWIFT infrastructure. China's participation in mBridge, a central bank digital currency project involving the UAE, Hong Kong, and Thailand, points to a longer-term ambition: building payment channels that do not rely on U.S.-dominated financial infrastructure.

​

Russia, cut off from Western systems, now conducts much of its oil trade with China in renminbi and rubles. Iraq allowed trade settlement with China in yuan for the first time in 2023. These shifts are real, but their scale remains modest. The renminbi still accounts for only a small share of global foreign exchange reserves and cross-border transactions compared with the dollar’s dominant position.

​

The constraints are structural, not merely political. The dollar's primacy rests on foundations that no other country can yet match: the depth and liquidity of U.S. financial markets, the vast stock of Treasury securities available as safe assets, and the rule of law and open capital account that allow investors to move funds freely. The renminbi, by contrast, operates within a partially closed financial system under significant state control. Countries may seek to diversify away from dollar exposure, but in moments of stress they continue to rely on dollar markets for liquidity and stability.

​

A More Fragmented Future

The most plausible outcome is gradual fragmentation rather than outright replacement.

​

Settlement patterns are becoming more regionally differentiated. Bilateral energy deals in non-dollar currencies are likely to increase. U.S. sanctions may become marginally less effective as alternative payment channels expand. The global monetary system could grow more multipolar in practice, even as the dollar retains its commanding position in reserves, trade invoicing, and international finance.

​

Saudi Arabia’s position is perhaps the clearest indicator. Riyadh has not abandoned the petrodollar; it still prices oil in dollars and holds vast reserves in U.S. assets. But it has joined BRICS initiatives, deepened ties with Beijing, and explored alternative payment infrastructure. The kingdom that helped entrench the petrodollar in 1973 now has enough strategic options to hedge its alignment with Washington.

​

For the United States, this points to a gradual narrowing of what has been called the “exorbitant privilege”, the ability to borrow cheaply and sustain external deficits because global demand for dollars remains structurally high. That privilege will not disappear overnight. But in a world where alternatives exist, even at the margins, maintaining dollar centrality may become more costly.

​

The petrodollar system is not collapsing; it is being diluted. Recent U.S. moves in Venezuela, tightening control over crude production and exports, demonstrate that American leverage over energy markets remains significant. The dollar’s foundations remain stronger than any rival’s, but its exclusivity is eroding at the edges. What is emerging is not a new monetary hegemon, but a more competitive monetary order. The era of unquestioned dollar dominance is giving way to one in which that dominance must be defended rather than assumed.
