Finn's Take· TL;DRWith America's national debt racing toward $40 trillion, the United States faces a critical choice between boosting exports through a weaker dollar and maintaining currency stability. Former Dallas Federal Reserve President Robert Kaplan argues that with such massive debt levels, stability of the currency probably trumps exports .
The debate comes as U.S. debt currently stands at $38.57 trillion according to the Peter G. Peterson Foundation , putting the nation in uncharted fiscal territory. While Kaplan acknowledges that "a weaker dollar boosts exports," he believes the sheer scale of America's borrowing fundamentally changes the equation.
Kaplan attributed the dollar's recent slump to investors buying some tail-risk protection by hedging the currency , suggesting market participants are already positioning for potential volatility. Yet demand for U.S. stocks remains high, contradicting fears of a "sell America" trade .
The U.S. has long enjoyed the "exorbitant privilege" of the dollar serving as the world's reserve currency. With such built-in demand for dollar assets like Treasury bonds, the government can borrow money at lower rates than would otherwise be possible .
This privileged position becomes even more crucial as interest costs on the debt surged to roughly $1 trillion last year, consuming a near-record 18% of federal revenue—an amount comparable to the entire Medicare budget . Any erosion of dollar dominance could dramatically increase borrowing costs at precisely the wrong moment.
Trump's efforts to upend the postwar global order have created doubts about U.S. financial dominance and the sustainability of the national debt if that advantage disappears . The stakes couldn't be higher for maintaining confidence in American financial leadership.
Despite the debt concerns, Kaplan pointed to the overall health of the American economy and prospects for robust growth as continued draws for investors, noting "there's a lot of strengths in the United States in terms of innovation, very strong year for GDP growth coming" .
Rather than running away from the U.S., markets are managing risk by seeking some alternative safe havens like gold . This suggests investors aren't abandoning America but are hedging their bets in an uncertain environment.
Interestingly, some economists argue a falling dollar might actually help Treasury demand. Foreign central banks, especially those in export-oriented Asian economies, have an incentive to buy Treasuries to stop their currencies from rising against the dollar, meaning "Dollar weakness mobilizes new demand" .
With the national debt now effectively equal to the size of the entire U.S. economy, experts warn the country could ultimately experience various types of crises if debt continues growing faster than the economy . The window for maintaining both fiscal flexibility and currency stability is narrowing.
The challenge ahead requires threading the needle between supporting American competitiveness through trade and preserving the dollar's unique global role. As debt approaches $40 trillion, policymakers face increasingly difficult trade-offs where traditional economic tools may no longer provide easy answers.
The coming years will test whether America can maintain its financial privileges while managing unprecedented debt levels. The outcome will shape not just domestic economic policy but America's role in the global financial system for decades to come.
