How the US Dollar Affects the Economy and Global Power

How the US dollar affects the economy is central to understanding today’s global financial system, and in this episode of The WealthAbility Show, Tom Wheelwright sits down with economist Barry Eichengreen to break down what’s really happening to the dollar—and why it matters for investors and business owners.

The US dollar remains the dominant global currency, used in the majority of cross-border transactions, foreign reserves, and financial markets worldwide . But that dominance is not guaranteed. Rising geopolitical tensions, expanding US debt, and increasing use of financial sanctions are pushing other countries to explore alternatives.

You’ll learn why the dollar’s reserve status gives the United States major advantages—like lower borrowing costs, global demand for Treasury bonds, and safe-haven capital flows during crises. Barry also explains how shifts in global confidence, policy uncertainty, and conflicts in regions like the Middle East can weaken the dollar’s position over time.

This episode also explores the long-term risks, including growing federal debt, potential investor pullback, and how global diversification away from the dollar could reshape markets. You’ll understand how interest rates, inflation, and global capital flows are all tied to the strength of the dollar.

If you want to understand the macro forces driving markets—and how changes in the dollar could impact your investments, taxes, and long-term wealth—this episode provides a clear, strategic framework.
