- 80% of global trade still relies heavily on the US dollar, despite predictions of its decline.
- The majority of US dollar-denominated transactions occur outside of the United States in a largely unregulated shadow system.
- The petrodollar system, a supposed key to US dollar dominance, is largely a myth with no formal treaty or cartel enforcing dollar-only oil sales.
- Countries regularly trade oil in non-dollar currencies, contradicting the narrative of dollar-only oil sales.
- The US dollar’s global dominance is more a result of eurodollars and a lack of a suitable alternative than any formal agreement.
On a quiet street in London, just a stone’s throw from the Bank of England, some of the world’s most consequential financial transactions take place—not in pounds, euros, or yen, but in U.S. dollars. These are not dollars held in American banks, nor are they controlled by the Federal Reserve. They are eurodollars: U.S. dollar-denominated deposits held in banks outside the United States, forming a vast, largely unregulated shadow of the global financial system. Trillions of dollars circulate through this offshore network daily, funding everything from corporate loans in Asia to sovereign debt in Latin America. This hidden architecture—often overlooked in popular discourse—holds the key to understanding why the U.S. dollar remains unshaken as the world’s dominant currency, despite years of predictions about its decline and the much-touted rise of alternatives like the Chinese yuan or digital currencies.

The Myth of the Petrodollar’s Power
\n
For decades, a compelling narrative has held that the U.S. dollar’s global dominance rests on the so-called “petrodollar” system—an arrangement allegedly struck in the 1970s whereby oil-exporting nations agreed to price and sell oil exclusively in dollars, thereby forcing every nation to hold dollars to buy energy. While politically evocative, this narrative is more myth than reality. There is no formal treaty or cartel enforcing dollar-only oil sales, and countries routinely trade oil in non-dollar currencies when it suits them. The real engine of dollar dominance lies elsewhere: in the eurodollar market, the largest pool of short-term credit in the world. According to the Bank for International Settlements, over $13 trillion in eurodollar deposits existed as of 2023, with trading volumes dwarfing those in U.S.-based markets. This offshore dollar system allows global banks to lend and borrow in dollars without regulatory oversight from the Federal Reserve, creating unparalleled liquidity and convenience.

How the Eurodollar System Took Root
\n
The eurodollar market emerged not from geopolitics, but from financial ingenuity and Cold War-era pragmatism. In the 1950s, Soviet bloc countries, wary of holding dollars in U.S. banks due to fears of asset freezes, began depositing their dollar earnings in European banks—hence the term “eurodollar.” These banks, in turn, lent the funds to other international borrowers, creating a self-sustaining offshore dollar credit system. By the 1970s, the market had grown exponentially, fueled by oil revenues recycled through London banks—a process known as “petrodollar recycling,” which further entrenched dollar usage but did not create it. The eurodollar system proved resilient because it offered higher yields, fewer regulations, and greater flexibility than domestic U.S. markets. Over time, it became the preferred medium for international trade finance, corporate borrowing, and sovereign debt issuance.

The Institutions and Minds Behind the System
\n
The persistence of the dollar’s dominance is not the result of a single mastermind or policy, but of a network of central banks, commercial lenders, and financial engineers who rely on dollar-based infrastructure. Institutions like the Bank of International Settlements and major global banks—HSBC, Citigroup, Deutsche Bank—operate daily within the eurodollar framework, pricing risk, issuing bonds, and settling trades in offshore dollars. Central banks, even those seeking to diversify reserves, continue to hold dollar-denominated assets because of their unmatched liquidity and depth. While nations like China and Russia have pushed for de-dollarisation in rhetoric, their actions tell a different story: Chinese banks are active participants in the eurodollar market, and Russia’s pre-2022 financial system was deeply integrated into dollar-based clearing networks. The inertia is not ideological but practical—no alternative offers the same scale, stability, or network effects.

Consequences for Global Economic Power
\n
The endurance of the dollar through the eurodollar system has profound implications. It grants the United States significant financial leverage, including the ability to impose sanctions that cut off access to dollar clearing, as seen with Iran and, more recently, Russia. However, it also exposes the global economy to U.S. monetary policy shifts, as tightening by the Federal Reserve can trigger liquidity crunches in offshore dollar markets—a phenomenon witnessed during the 2008 crisis and again in 2020. Emerging markets, in particular, face heightened vulnerability when dollar funding dries up, leading to currency collapses and debt distress. Meanwhile, efforts by other nations to create alternatives—such as China’s Cross-Border Interbank Payment System (CIPS)—have made limited headway due to lack of trust, shallow markets, and capital controls.
\n
The Bigger Picture
\n
The debate over de-dollarisation often misses the deeper structural realities of global finance. The dollar’s dominance is not sustained by oil or coercion, but by a self-reinforcing ecosystem of trust, liquidity, and institutional habit. As long as global markets rely on dollar-denominated contracts, debt, and trade finance—much of it operating beyond U.S. jurisdiction—the greenback will remain central. Real change would require not just political will, but the creation of equally deep, open, and trusted financial markets elsewhere, a challenge no current rival is close to meeting. The myth of the petrodollar distracts from this more complex, enduring truth.
\n
What comes next is unlikely to be a sudden collapse of dollar hegemony, but rather a slow, uneven evolution. Fragmentation may increase, with regional blocs using local currencies for bilateral trade, yet the bulk of global finance will likely remain dollar-centric for decades. The eurodollar market, invisible to most, will continue to underpin this reality—quietly, powerfully, and without fanfare.
