What Finally Breaks the Dollar? Currencies Don’t Last Forever
What Finally Breaks the Dollar? Currencies Don’t Last Forever
David Lin: 4-22-2026
In an era defined by rapid geopolitical shifts, persistent inflation, and the rise of digital finance, the question of what constitutes “money” is more complex than ever.
To unpack these challenges, financial journalist David Lin recently sat down with Professor Barry Eichengreen, a world-renowned economist from UC Berkeley and author of the timely new book, Money Beyond Borders.
Their conversation provides a masterclass on the current state of the global financial system, the Federal Reserve’s uphill battle, and whether the U.S. dollar can maintain its “exorbitant privilege” in an increasingly fragmented world.
The Federal Reserve is currently caught between a rock and a hard place. Managing its dual mandate of price stability and maximum employment has become significantly more difficult due to external shocks—ranging from energy crises to lingering supply chain issues.
Professor Eichengreen emphasizes that the Fed’s greatest asset isn’t just its policy tools, but its independence. As political pressures mount from the White House and Capitol Hill, Eichengreen warns that any erosion of central bank autonomy would be catastrophic. To maintain credibility in its fight against inflation, the Fed must remain insulated from the short-term whims of the political cycle.
One of the most debated topics in macroeconomics today is “de-dollarization.” While headlines often suggest the dollar is on the verge of collapse, Eichengreen offers a more nuanced perspective.
He argues that the dollar’s “safe haven” status remains intact primarily because there is no viable alternative. The sheer depth and liquidity of the U.S. Treasury market are unmatched by any other nation. However, this dominance is not a birthright.
To understand where the dollar is going, we must look at where international currencies have been. Eichengreen draws parallels between the dollar and historical giants like the Roman denarius and Spanish silver coins.
History shows that international currency status is built on a four-legged stool:
1. Economic and financial strength.
2. Military power.
3. Durable international alliances.
4. Sound governance.
When one of these legs fails—as seen with the decline of past empires—the currency inevitably follows. The lesson for the United States is clear: economic dominance alone isn’t enough to sustain a global reserve currency.
The conversation took a forward-looking turn as Lin and Eichengreen discussed the digital revolution. While blockchain technology is set to transform how we move value, Eichengreen remains a “crypto-skeptic” regarding Bitcoin’s role as a currency. He argues that Bitcoin fails as a stable store of value or a practical unit of account.
Interestingly, Eichengreen critiques the current U.S. legislative resistance to a digital dollar, suggesting that relying solely on private stablecoins may be a misguided path that ignores the stability offered by central bank backing.
As Professor Eichengreen details in Money Beyond Borders, the future of the dollar depends less on technology and more on American political stability. Sound fiscal policy and the ability to maintain credible global alliances are the true bedrocks of the financial system.
Global currency status is contingent. It relies on international trust—a trust that is earned over decades but can be lost much faster.
