The U.S. dollar has long reigned supreme as the world’s primary reserve currency, underpinning global trade, financial systems, and economic stability. But recent commentary from Mark Carney, former Governor of the Bank of England, suggests that this dominance may not last forever—especially with the rise of digital currencies backed by central banks.
Carney proposed a bold vision: a new form of digital money, supported by a network of major central banks, could one day replace the dollar as the global standard. This idea isn’t just theoretical—it reflects growing concerns about the current international monetary system and opens the door to a more balanced, stable, and inclusive financial future.
Let’s explore the forces shaping this potential shift, the limitations of today’s dominant currencies, and how central bank digital currencies (CBDCs) might redefine global finance.
The Dollar’s Historical Dominance
Since the Bretton Woods Agreement in 1944, the U.S. dollar has served as the backbone of the global financial system. At that time, world leaders established a framework where major currencies were pegged to the dollar, which was itself convertible to gold. Even after the gold standard ended in 1971, the dollar retained its privileged status due to America’s robust economy, deep capital markets, and geopolitical influence.
As Philip Weckel, Head of Research at Ostrum AM, noted:
“The dominant currency has always been that of the most powerful political force.”
According to IMF data from 2019, the dollar accounted for nearly 62% of global foreign exchange reserves, far ahead of the euro at 20.2%. Despite China being the world’s second-largest economy, the renminbi made up only about 2%—highlighting the entrenched position of the dollar.
This dominance allows the U.S. to borrow cheaply, exert financial influence globally, and shape international economic policy. But it also means that fluctuations in the U.S. economy ripple across the world.
Why the Dollar Is Losing Its Shine
While still dominant, the dollar’s unchallenged role is increasingly questioned. Globalization, shifting trade patterns, and rising economic powers like China are eroding its relative influence.
Mark Carney pointed out a critical flaw:
“Conditions in the U.S. have a major impact on countries’ trade performance and financial conditions—even those with limited direct exposure to the U.S. economy.”
When the dollar strengthens, it increases debt burdens for emerging market nations, many of which hold loans denominated in U.S. dollars. A stronger dollar makes repayments more expensive, often triggering financial stress or crises.
Carney argued that overreliance on a single national currency creates systemic risk. In his view, “in the long run, we need to change the game.”

The Role of Central Banks in a New Monetary Order
So what’s the alternative? Carney suggested that public institutions—specifically central banks—could lead the way in creating a more equitable digital currency system.
He posed a key question:
“Would this new form of crypto not be best supplied by the public sector through a network of central bank digital currencies?”
Unlike decentralized cryptocurrencies such as Bitcoin, central bank digital currencies (CBDCs) would be issued and regulated by national monetary authorities. They could be designed to operate across borders, potentially forming a multinational digital reserve currency.
This approach offers several advantages:
- Stability: CBDCs would avoid the extreme volatility seen in private cryptocurrencies.
- Trust: Backed by governments and central banks, they would carry institutional credibility.
- Efficiency: Enable faster cross-border payments and reduce reliance on correspondent banking networks.
However, many policymakers remain cautious. Cryptocurrencies like Bitcoin and Libra (now Diem) have raised red flags over regulatory oversight, money laundering risks, and financial stability.
Even U.S. President Donald Trump criticized Bitcoin and Libra, calling them “not money” and emphasizing their lack of intrinsic value compared to the dollar.
The Rise and Challenges of Private Digital Currencies
Carney specifically referenced Libra, Facebook’s proposed digital currency announced in June 2019. Unlike Bitcoin, Libra was designed to be stable by being pegged to a basket of fiat currencies and assets.
The goal? To avoid wild price swings and make it usable for everyday transactions—especially for the unbanked population worldwide.
But Libra faced immediate backlash from regulators and central bankers. One major concern: monetary sovereignty.
Agnes Bénassy-Quéré, an economist at the Paris School of Economics, observed:
“Central banks are somewhat annoyed by Facebook’s attempt to privatize money.”
While Bitcoin operates on a decentralized network with no single controlling entity, Libra would be governed by a consortium of companies—including Facebook—raising concerns about corporate control over global payment systems.
Moreover, critics worry that private digital currencies could undermine national monetary policies, challenge tax collection, and enable illicit finance if not properly regulated.

Can a Global Digital Currency Really Replace the Dollar?
Carney’s proposal envisions a synthetic hegemonic currency—a digital reserve asset built on a network of CBDCs from multiple major economies. This wouldn’t belong to any single nation but would function as a neutral, efficient alternative to the dollar.
Such a system could:
- Reduce dependency on U.S. monetary policy
- Lower transaction costs for international trade
- Enhance financial inclusion
- Improve crisis resilience
Countries like China are already moving fast. The People’s Bank of China has been testing its digital yuan (e-CNY) since 2020, positioning itself as a leader in CBDC development.
Meanwhile, the European Central Bank and others are exploring digital euro initiatives. These efforts suggest that while no single digital currency may dethrone the dollar overnight, the foundation for change is being laid.
Frequently Asked Questions (FAQ)
Q: Can cryptocurrency really replace the U.S. dollar?
While current cryptocurrencies like Bitcoin are too volatile to serve as global reserve currencies, central bank digital currencies (CBDCs) could collectively challenge dollar dominance over time—especially if integrated into a multinational framework.
Q: What is Mark Carney’s proposed solution?
Carney advocates for a synthetic hegemonic currency—a digital reserve asset powered by a network of CBDCs from major economies—to reduce reliance on the U.S. dollar and create a more balanced global financial system.
Q: Why are central banks wary of private cryptocurrencies?
Regulators fear that private digital currencies like Libra could threaten monetary sovereignty, enable financial crime, destabilize national economies, and concentrate too much power in corporate hands.
Q: How does dollar dominance affect other countries?
When the U.S. raises interest rates or experiences economic shifts, it causes capital flows and currency fluctuations worldwide. Many emerging markets face higher debt costs when the dollar strengthens—making them vulnerable to external shocks.
Q: Is China’s digital yuan a threat to the dollar?
Not immediately. But as part of broader CBDC adoption and China’s growing trade influence, the digital yuan could gradually erode dollar usage in regions aligned with Chinese economic partnerships.
Q: What role does blockchain play in future currencies?
Blockchain technology enables secure, transparent, and efficient transaction records—key features for both CBDCs and private digital currencies. Its evolution will shape how money moves globally in the coming decades.

Final Thoughts
The U.S. dollar remains the cornerstone of global finance—but its era of unquestioned dominance may be entering a new phase. With rising geopolitical competition, technological innovation, and calls for reform, alternatives are emerging.
Mark Carney’s vision of a central bank-backed digital currency network offers a compelling path forward: one that prioritizes stability, fairness, and global cooperation over national advantage.
As nations accelerate their CBDC programs and rethink monetary architecture, one thing is clear—the future of money is going digital. And while no single currency may replace the dollar overnight, the foundations for transformation are already being built.
