Triffin Dilemma

The Triffin Dilemma, named after economist Robert Triffin, describes a fundamental conflict of interest that arises when a national currency also serves as the global reserve currency. First articulated in the 1960s during debates over the U.S. dollar’s role under the Bretton Woods system, the dilemma highlights the tension between short-term domestic economic policy goals and long-term international monetary stability. Triffin argued that the country issuing the world’s reserve currency—at the time, the United States—must supply the global economy with enough liquidity (in the form of its own currency) to facilitate trade and investment, even if that requires running persistent current account deficits.

According to Triffin, in order to meet global demand for reserve assets, the United States would need to continually export more dollars than it received through trade, thereby undermining confidence in the dollar’s long-term value and its convertibility to gold (which underpinned the system at the time). Conversely, if the U.S. chose to preserve the dollar’s value and limit its deficits, there would be insufficient global liquidity, leading to deflationary pressures and restricted economic growth worldwide. Thus, the Triffin Dilemma reveals an inherent instability in any system where the domestic monetary policies of the reserve currency issuer are misaligned with the global demand for reserves.

The Triffin Dilemma remains highly relevant today, even after the collapse of Bretton Woods in 1971, as the U.S. dollar continues to function as the dominant reserve currency. The United States still faces the challenge of balancing domestic fiscal responsibility with its role as the de facto banker to the world. Critics argue that this imbalance has contributed to global financial volatility, unsustainable debt accumulation, and recurring crises. The dilemma also fuels discussions about alternatives to the dollar-centric system, such as expanding the role of the International Monetary Fund’s Special Drawing Rights (SDRs) or increasing the use of digital or regional currencies in international trade.
