The World's Favorite Currency
The US dollar is the closest thing the world has to a global currency. It is the preferred choice for most international transactions and is held as a reserve currency by many countries, whether friendly or hostile to the US. The dominance of the dollar began in earnest after World War II when the US emerged as a global superpower. Investors trust the dollar and US assets, such as US Treasuries, because they are seen as safe places to store wealth in both good times and bad. This trust is underpinned by the strength and stability of the US economy and its laws.
Why Is the Dollar So Dominant?
1. It’s Big
The size of the US economy is a primary reason for the dollar's dominance. The US economy is massive, almost as large as the economies of China, Japan, and Germany combined. This economic heft is supported by the largest and most liquid capital markets in the world. US stock markets, home to many of the world's wealthiest and most innovative companies, dwarf those of other countries. The US bond markets are even larger, with the US Treasury market alone having swelled to $27 trillion. When companies or countries need to raise cash, they are most likely to turn to US markets to sell stock, issue bonds, or take out loans. The abundance of dollar-denominated assets makes them some of the most "liquid" in the world, meaning they can be easily bought and sold.
2. It’s Stable
US banknotes may carry the motto "In God We Trust," but it is the strength of American institutions that underpins the dollar's reliability. The US has a strong rule of law that usually prevents arbitrary uses of political power, and its elections have historically been free and fair. The Federal Reserve, the US central bank, has a strong record of maintaining its independence, unlike central banks in many other countries. Moreover, the US has never defaulted on its debt or experienced hyperinflation. These qualities make the dollar an attractive store of value and one of the safest bets when markets become volatile. In fact, people rush to the dollar even when the US itself is in distress. For example, during the US housing meltdown that started in 2008, the dollar rose more than 26% against a basket of six other major currencies in the span of 12 months.
3. It’s Entrenched
The dollar benefits from the power of incumbency. The world’s reserve currency has changed over centuries, but not without significant crises, shifts in economic dominance, and the passage of many years. British sterling began to lose its global prominence in the 1890s, after the US overtook the UK as the world's largest economy. However, it took another half-century, two world wars, and a fiscal crisis in the UK for the greenback to dethrone the pound. Today, the obstacles to replacing the dollar are even greater. The world's financial systems are more closely knit and engineered around the dollar than ever before. Supplanting the dollar might require not only an economic or major calamity but also a wholesale change in the way financial transactions are executed.
Who Benefits from a Strong Dollar?
For the US:
One major benefit for the US is that the government can borrow vast amounts of money at relatively low interest rates. Trust in the dollar allows US borrowers to pay lower interest rates for home mortgages, auto loans, and corporate debt. This helps reinforce the economic and financial dominance that made the dollar No. 1 in the first place. Additionally, being at the center of the global financial network means that the US is often shielded from the reverberations of economic troubles elsewhere in the world.
For Everyone Else:
About 70% of foreign debt is issued in dollars, more than triple the amount issued in euros and 30 times the amount issued in yuan. This means the economic fortunes of many countries are tied to the US. When the US Federal Reserve raises interest rates, it can push up the value of the dollar, impacting other countries. These countries may feel compelled to raise their own interest rates to prevent their currencies from falling against the dollar. However, if their economies do not need higher rates, this can stifle growth. Alternatively, if they allow their currencies to slide, it can fuel inflation and make dollar-denominated debt more expensive to pay off with local currency, potentially leading to financial crises, especially in developing countries.
The US also uses the dollar as a foreign policy tool. As the source of the world’s pre-eminent currency, the US controls many of the world's largest financial institutions and networks used for commerce and finance. This allows the US to use the dollar as a weapon by cutting off individuals, companies, and governments from the global financial system. For instance, after Russia invaded Ukraine in 2022, the US and the European Union cut off seven Russian banks from SWIFT, the global financial messaging service. The US also immobilized some Russian assets and halted the central bank’s ability to trade in dollars. These actions caused the ruble to plunge 30% against the dollar immediately after the first round of sanctions, although the currency has since rebounded.
What Threatens Dollar Dominance?
Debt and Dysfunction:
No federal government spending can happen without congressional approval, and Congress must periodically authorize increases in a separate "debt limit" to account for new deficit spending. These must-pass votes provide ample opportunity for lawmakers to use their leverage to press for unrelated demands. Repeated brinkmanship over the borrowing cap has, on several occasions, prompted two of the three major credit assessors to strip the US of its top debt rating. Each time Congress flirts with default, the dollar earns a fresh black eye.
Abusing the Privilege:
There are risks stemming from the US overusing or abusing its privileged position at the center of the global currency universe. If the US gets too heavy-handed or unpredictable with its economic sanctions, some countries could get serious about finding ways to reduce their exposure to the dollar. The BRICS club, which includes Brazil, Russia, India, China, and South Africa, is recruiting other nations to join and shift away from the dollar, although progress has been limited.

Possible Alternatives
Euro:
The euro is the clear No. 2 globally, as measured by the volume of international transactions, reserve holdings, and the size of its capital markets. However, the euro faces significant hurdles. The currency is relatively young and has had a rocky history, including the 2011 debt crisis that nearly dismantled the eurozone. Budgetary decisions are still made at the national level, even as monetary policy is set for the entire euro area.
Chinese Yuan:
China is America’s largest geopolitical and economic rival, and there has been talk for years that the yuan might one day supplant the dollar. While Beijing has taken steps to encourage international use of its currency, the government is handicapped in several ways. China’s economy is still smaller than the US’s, and its capital markets remain tiny by comparison. Even if countries and companies wanted to hold a big share of their reserves in yuan, there aren't enough liquid assets for investors to park their yuan in. The Chinese system of government, which exerts strict controls over moving capital across borders, and the lack of independence of its institutions also pose significant challenges.
Gold or Bitcoin:
Some people contend that the real heir to the dollar might be gold or Bitcoin. Gold has been a store of wealth for millennia, but its use as a primary form of payment proved risky to financial stability, leading to the abandonment of the traditional gold standard. Bitcoin and other cryptocurrencies are much newer and have yet to show the kind of stability and widespread acceptance needed for a global reserve currency.
Is the Dollar Really Under Threat?
Mostly, no. Despite increasing discontent with the dollar’s dominance and the US’s use of economic sanctions, there is a lot more talk about a post-dollar world than action. There is no clear contender ready to take over any time soon. The world once regarded the Florentine florin and the Dutch guilder as pillars of international finance, and now those currencies are footnotes in history books.

Key Risks to the Dominance of the US Dollar
While the US dollar has long been the world's dominant currency, there are several risks that could threaten its supremacy. These risks stem from both internal and external factors, including political dysfunction, economic challenges, and actions by other countries to reduce their dependence on the dollar. Here are some key risks to consider:
1. Political Dysfunction
One of the most significant risks to the dollar's dominance is the increasing political dysfunction within the United States. The federal government’s ability to function effectively is frequently hampered by partisan gridlock and brinkmanship over fiscal policies. Key areas of concern include:
- Debt Ceiling Crises: The US government must periodically raise the debt ceiling to continue borrowing money to fund its obligations. Political standoffs over raising the debt ceiling can lead to government shutdowns and threats of default, which undermine global confidence in the dollar.
- Government Shutdowns: Political battles over budget approvals can result in government shutdowns. These shutdowns not only disrupt domestic operations but also signal instability to global investors, shaking their trust in the reliability of the US government.
2. High National Debt
The US national debt has been growing steadily, reaching levels that are high compared to the country's GDP. High levels of debt can raise concerns among investors about the long-term sustainability of US fiscal policies. Key issues include:
- Interest Payments: As debt levels rise, so do the interest payments required to service that debt. This can limit the government’s ability to invest in other critical areas such as infrastructure, education, and defense.
- Inflation: High levels of debt can also contribute to inflation if the government resorts to printing more money to meet its obligations. This can erode the value of the dollar and diminish its attractiveness as a reserve currency.
3. Overuse of Economic Sanctions
The US frequently uses economic sanctions as a tool of foreign policy to exert pressure on other nations. While effective in certain contexts, the overuse or unpredictability of sanctions can drive other countries to seek alternatives to the dollar. Risks include:
- Alienating Allies: Even allied countries may seek to reduce their reliance on the dollar to avoid being caught in the crossfire of US sanctions on other nations.
- Encouraging Alternatives: Countries targeted by US sanctions, such as Russia and Iran, are actively seeking alternatives to the dollar. The development of alternative payment systems and reserve currencies could weaken the dollar's global dominance.
4. Emergence of Alternative Currencies
Several currencies and assets are being positioned as potential alternatives to the dollar. These include the euro, the Chinese yuan, and digital currencies like Bitcoin. Key challenges posed by these alternatives include:
- Euro: The euro is the second most used currency in international transactions. The European Union has been working to strengthen its financial systems, but the euro faces its own challenges, including economic disparities among member states and political uncertainties such as Brexit.
- Chinese Yuan: China is actively promoting the yuan as a global currency. While its use is growing, the yuan faces significant hurdles, including capital controls and a lack of transparency in Chinese financial markets.
- Digital Currencies: Cryptocurrencies like Bitcoin offer a decentralized alternative to traditional currencies. While they are gaining popularity, they also come with high volatility and regulatory challenges that currently limit their viability as stable reserve currencies.
5. Economic Instability and Recession
The US economy's health directly impacts the strength of the dollar. Economic instability or a severe recession could erode confidence in the dollar. Key factors include:
- Trade Deficits: Persistent trade deficits can weaken the dollar by increasing the supply of dollars held by foreign entities.
- Slow Growth: If the US economy experiences prolonged slow growth or stagflation (a combination of stagnation and inflation), it could reduce the attractiveness of dollar-denominated assets.
6. Global Efforts to Reduce Dollar Dependence
Several international initiatives aim to reduce global dependence on the dollar. These efforts include:
- BRICS Initiatives: The BRICS countries (Brazil, Russia, India, China, and South Africa) are exploring ways to trade with each other in their local currencies instead of the dollar.
- European Alternatives: The European Union is developing financial instruments and mechanisms to increase the use of the euro in global trade and finance.
- Asian Infrastructure Investment Bank (AIIB): China-led initiatives like the AIIB promote alternatives to the dollar for infrastructure financing in Asia.
Conclusion
While the US dollar remains the world's dominant currency, it faces several risks that could threaten its supremacy. Political dysfunction, high national debt, overuse of economic sanctions, the emergence of alternative currencies, economic instability, and global efforts to reduce dollar dependence all pose significant challenges. The future of the dollar's dominance will depend on how the US manages these risks and adapts to a rapidly changing global financial landscape.
