An old video of U.S. Vice President JD Vance has revived debate over whether the dollar’s role as the world’s dominant reserve currency ultimately benefits the U.S. economy.
Vance, who was still a senator when the comments were recorded, argued that global demand for dollars brings clear advantages, including cheaper imports and easier government borrowing. But it can also strengthen the currency, making U.S. exports less competitive.
A recent Forbes analysis linked the argument to the Triffin dilemma, which describes the tension created when a national currency also serves as the world’s primary reserve asset.
Dollar Dominance Has a Cost
The Triffin dilemma dates back to the Bretton Woods era, when the U.S. had to supply enough dollars for global trade while maintaining convertibility into gold. That system eventually broke down when President Richard Nixon ended gold convertibility in 1971.
The modern system is different, but the basic conflict remains. Foreign investors still hold enormous amounts of U.S. assets, while Washington is simultaneously trying to strengthen domestic manufacturing and exports.
Stablecoins could reinforce dollar dominance rather than replace it. The GENIUS Act ties regulated payment stablecoins more closely to liquid dollar assets, including U.S. Treasuries.
Bitcoin Offers a Neutral Alternative
Bitcoin represents a different model because its supply is not tied to any government’s debt, fiscal policy or trade balance.
That makes it theoretically attractive as a neutral reserve asset. The U.S. has already taken a limited step in this direction through its Strategic Bitcoin Reserve, created in March 2025 using BTC obtained through government forfeitures. The broader Bitcoin reserve debate has since become part of U.S. digital-asset policy.
Still, Bitcoin remains far from replacing traditional reserves. Volatility, custody risks and limited central-bank adoption remain major barriers.
Gold continues to hold a much stronger position. Central banks purchased more than 1,000 tonnes annually in 2022, 2023 and 2024, reinforcing its role as the leading politically neutral reserve asset.
