A Return to the 19th Century

2nd Quarter, 2025

Barriers to open trade are rising across the world at a pace unseen in decades, a cascade of protectionism that harks back to the isolationist fervor that swept the globe in the 1930s and worsened the Great Depression.

Economists and historians say the flurry of recent moves suggest the world could be heading toward the largest, broadest surge in protectionist activity since the U.S. Smoot-Hawley Tariff Act of 1930 touched off a global retreat behind tariff walls that lasted until after World War II.

Investors have slashed holdings of US equities by the most on record, according to Bank of America Corp.’s latest survey, underscoring the massive rotation that’s underway in global markets.

While high valuations and tepid economic growth have made investors jittery about the US, European markets are riding a wave of newfound optimism with Germany getting ready to unlock billions in defense and infrastructure spending.

Investors active today can be forgiven if the events of the past few months have been a bewildering experience. The sudden reintroduction of high tariffs on imported goods has brought policy tools back to life that have not been used since before World War II, more than ninety years ago. Yet even then, tariffs were fading as a preferred policy tool. The legacy of the Smoot-Harley Tariff Act of 1930 is forever stained by the Great Depression it helped deepen, and that traumatic experience marked the end of broad-based tariffs.

In order to return to a time when tariffs were viewed more favorably, more along the lines of how they appeared to be viewed by the new administration, we have to venture all the way back to the 19th century.

In the early 1800s, tariffs, or customs duties as they were then commonly known, were the primary source of revenue for the fledgling Federal Government. And while there were some notable departures during times of crisis, customs duties remained a primary source of revenue for the Federal Government throughout the 19th century.

When the constitution was adopted and the Treasury Department was first organized by Alexander Hamilton in the 1790s, duties on goods imported from abroad accounted for over 90% of the revenue of the Federal Government. The debate over powers of taxation had been a central issue during the Constitutional Convention, and the idea of direct taxation of citizens by the Federal Government remained a divisive issue.
