The U.S. dollar has fallen nearly 10% against a basket of major currencies since the start of 2025, its worst annual performance since 2017, fueling widespread commentary about the potential end of dollar dominance as the linchpin of the global financial system. Yet a growing chorus of economists and currency strategists argue that recent speculation about the dollar's decline — particularly narratives around the rise of a 'petroyuan' as Saudi Arabia and Russia accept Chinese renminbi for increasing shares of oil payments — dramatically overstates the pace and probability of reserve currency transition.
The dollar remains the currency of denomination for approximately 88% of global foreign exchange market transactions, 58% of global foreign currency reserves held by central banks, and roughly 50% of international trade invoicing — shares that have changed minimally despite years of de-dollarization rhetoric. The most recent IMF Currency Composition of Official Foreign Exchange Reserves data shows the dollar's share declined by less than 2 percentage points over the past five years, while the yuan's share increased by just 1 percentage point to 2.8%.
Petroyuan: More Symbolic Than Systemic
The so-called petroyuan narrative gained momentum when China signed long-term yuan-denominated oil supply agreements with Saudi Arabia, Russia, and Iran. But analysts at Goldman Sachs and Deutsche Bank note that the yuan's non-convertibility on the capital account — meaning investors cannot freely move money in and out of China — represents a fundamental structural barrier to its use as a reserve currency. Central banks seek reserve assets they can liquidate in times of crisis without market impact, and no market exists of sufficient depth to absorb the scale of China's current account surpluses.
BNP Paribas currency strategist Calvin Tse points out that countries receiving yuan for oil sales have limited options for reinvesting the proceeds: Chinese government bonds offer decent yields, but capital controls mean the reinvestment is essentially trapped in China. 'Reserve diversification into the yuan is fundamentally constrained by China's capital account architecture,' Tse wrote in a note published this week.
When Could a Genuine Shift Occur?
Analysts who take the de-dollarization thesis more seriously argue that meaningful erosion of dollar dominance could occur over a 20-30 year horizon as China potentially opens its capital account, the euro area deepens its financial markets, or a multilateral digital currency alternative gains traction. A severe U.S. fiscal crisis or default — considered a remote risk but not impossible — could accelerate the timeline.
