American economist Kenneth Rogoff looks at the dominance of the U.S. dollar, how the currency came to be so powerful, and the forces that could threaten its supremacy.

The U.S. dollar has long been a symbol of power and prosperity.

For nearly a century, the dollar has guaranteed safe investment, underwritten billions of loans and exchanges, and helped the U.S. write the financial rulebook for the entire world.

But is time starting to run out for America's greatest asset?

In his 2025 book, Our Dollar, Your Problem, economist Kenneth Rogoff charts the rise of the U.S. currency, from the Second World War to the present era.

Rogoff looks at how the dollar's supremacy is being challenged today, from competing economic powers to domestic political pressures, and examines the turbulence of owning the most powerful currency the world has ever seen.
