The second term of Donald Trump’s presidency in the United States is certainly causing quite a stir in the global political and economic scene. One primary economic concern is the increase in tariffs on U.S. imports from key trading partners. As Trump attempts to steer the course of trade and tariffs, economists are pondering a critical question: What role will the U.S. Dollar play as a reserve currency in the future?
To better understand this question, we must first delve into the historical context. Amidst the chaos of World War II, a group of economists and government officials convened in Bretton Woods, New Hampshire, in the United States. Their aim was to establish a system promoting global financial stability and international trade, which led to the creation of the World Bank, International Monetary Fund, and the General Agreement on Tariffs and Trade (GATT).
Evolution of Foreign Exchange Markets
The Bretton Woods agreement also addressed the global exchange rate system. Prior to World War II, exchange rates were pegged to the Gold Standard, which had its advantages in controlling inflation but also lacked flexibility during crises, such as the wars. The new system pegged the U.S. Dollar to gold, and other currencies to the Dollar, effectively making the Dollar the world’s dominant currency. This move, however, brought about a significant dilemma for the global monetary system.
Triffin Dilemma: A Persistent Conundrum
The systemic flaw became evident in the 1950s, as the U.S. economy faced large trade deficits, leading to an overflow of U.S. Dollars globally. This was exacerbated by American efforts to curb communism and decolonization. Consequently, European and Japanese central banks hoarded their Dollar reserves, converting them to gold and depleting U.S. gold supplies.
In 1960, economist Robert Triffin presented a dilemma before the U.S. Congress. If the U.S. ceased its trade deficits, the global monetary system would falter due to a scarcity of reserves, potentially triggering an economic contraction and instability. Conversely, persistent deficits could undermine the Dollar’s value and confidence, eventually collapsing the system into a global crisis.
In 1971, President Richard Nixon’s decision to exit the Bretton Woods agreement led to its collapse, thereby relieving the U.S. of its gold reserve obligations. Yet, the nation’s trade deficits persisted unabated, exacerbating the problem over time.
Persistence of the U.S. Dollar as a Reserve Currency
Even after Bretton Woods’ collapse, the Dollar remains the international reserve currency. Pre-1971, the global system faced fewer financial crises, acting as a regulator for capital flows and crisis prevention. Post-1971, crises became more frequent, compelling central banks to stockpile U.S. Dollars, retaining the framework of the Bretton Woods system in spirit, if not in practice. As of 2024, forex reserves have soared from USD 1.3 trillion in 1995 to USD 12.7 trillion. While the Dollar’s share in these reserves has decreased from 70% in 2000 to 58% in 2024, it remains without equal as the "dominant currency paradigm" continues. Most international trade and financial transactions are still conducted in U.S. Dollars.
Trump’s Approach to the Dilemma
Now, let’s fast forward to Trump’s presidency. A key agenda for President Trump has been rectifying the U.S. trade imbalance, potentially rekindling the Triffin dilemma. Discussions on this tension have ebbed and flowed, particularly around the 2008 crisis, yet little has been done to directly address it. Trump’s administration has brought this to the forefront of policy, distinguishing it from previous administrations’ tendencies to let the market dictate.
Potential Scenarios Under Trump’s Presidency
Concerning how this steadfast dilemma will unfold under Trump, two scenarios are possible. In one, the U.S. trade deficit may indeed shrink. Alternatively, other nations might retaliate with steeper tariffs on U.S. exports, nullifying anticipated improvements.
In the midst of these possibilities, the future status of the Dollar remains uncertain. Although the Dollar’s share as a reserve currency has dwindled, it hasn’t been supplanted by another dominant currency like the Euro or Yen. Instead, there’s been a rise in reserves of non-major currencies, including the Australian Dollar, Yuan, and Canadian Dollar. Nonetheless, the U.S. Dollar still stands robust in international trade and finance. Only time will reveal how and if the Triffin dilemma will be resolved during Trump’s tenure.
