The dominance of a global reserve currency like the U.S. dollar provides significant benefits, including easier access to markets and lower borrowing costs.
The Triffin dilemma illustrates the risks of maintaining a global reserve currency, as it necessitates balance of payments deficits that threaten its long-term stability.

Understanding Global Reserve Currencies
There are roughly 160 currencies used around the world, but only a few are recognized as global reserve currencies, which are essential for international trade and finance. These currencies, like the U.S. dollar, provide significant benefits to the issuing country, such as easier access to international markets and lower borrowing costs. However, they also face inherent challenges, particularly in maintaining their value over time due to external demands. The historical context, from ancient empires to modern times, highlights that currencies can achieve dominance through widespread acceptance and trust in their stability.
The Triffin Dilemma Explained
The Triffin dilemma underscores the paradox faced by countries whose currency serves as the global reserve: in order to meet international demand, they must run persistent balance of payments deficits. This situation poses a risk to the currency's value, as continuous outflow can undermine confidence. Yale economist Robert Triffin identified this issue during the Bretton Woods era, predicting the system's collapse when the U.S. could no longer maintain its dollar-gold peg. The predicament remains relevant today, where the U.S. dollar's status continues to necessitate outflows of currency, potentially jeopardizing its stability.
Consequences of Being a Reserve Currency
Holding the status of a global reserve currency has far-reaching implications for a country's economy, particularly regarding trade deficits and investment behaviors. Nations using the reserve currency often experience trade deficits as their currency flows out to meet global demand, which can lead to a stronger exchange rate and competitive disadvantages. Moreover, foreign-held dollars often funnel back into U.S. investments, such as treasury notes and real estate, due to the demand for dollar-denominated assets. This interconnectedness of global finance illustrates that while being a reserve currency offers advantages, it also comes with notable economic complexities and risks.
Today, approximately 160 currencies are used worldwide. Some countries share the same currency, while others use the currency of another country.
However, not all currencies are equal. One currency always tends to become the dominant currency in international affairs, known as the global reserve currency.
There are benefits for the country that issues the global reserve currency. However, there are also major drawbacks, and the two cannot be separated.
