Discover the impact of Trump’s 2025 tariffs on the global economy and lessons from the Smoot-Hawley Tariff Act.
Trump’s Tariff Policy: A Revival of Smoot-Hawley? Where Is the World Economy Headed?
Since Donald Trump returned to the White House in 2025, his administration has once again rolled out an aggressive trade agenda, introducing sweeping tariffs at unprecedented levels. The U.S. has imposed a baseline 10% tariff on all imports, with rates as high as 100% on certain products and countries such as China—effectively igniting a new round of global trade wars.
This approach immediately recalls one of the most infamous episodes of protectionism in history: the 1930 Smoot-Hawley Tariff Act. At that time, the U.S. sought to protect its economy during the early days of the Great Depression by sharply raising tariffs. Instead of recovery, however, the policy triggered global retaliation, a collapse in international trade, and a deepening of the crisis.
The Smoot-Hawley Tariff: A Symbol of Protectionism Gone Wrong
In 1930, the U.S. Congress passed the Smoot-Hawley Tariff Act, imposing sweeping duties on imported goods. The intention was to safeguard domestic agriculture and manufacturing while reducing unemployment. The outcome was the opposite.
- Over 20,000 imported goods faced tariffs averaging above 40%
- More than 25 countries retaliated with tariffs of their own
- Global trade volumes plummeted by 66% between 1929 and 1934
- U.S. exports collapsed, and unemployment soared to over 25%
Most economists now view the Smoot-Hawley Act as a key factor that worsened and prolonged the Great Depression.

Trump’s Tariff Policy in 2025: A Repeat of History?
Trump had already leaned heavily on tariffs during his first term (2017–2021), especially in his trade war with China. But in his second term, the scope and intensity of his tariff agenda have expanded dramatically.
Key Measures
- A blanket 10% tariff on all imports
- Tariffs of 25–100% on targeted goods (Chinese products, steel, aluminum, etc.)
- Pressure on “unfair trade” partners such as China, India, and Mexico
Stated Objectives
- Protect U.S. manufacturing and jobs
- Reduce trade deficits and strengthen U.S. surpluses
- Maintain the U.S. dollar’s dominance as a reserve currency
- Use tariffs as leverage in global negotiations
Trump’s tariff policy, therefore, functions not only as an economic tool but also as a strategic instrument in reshaping global power dynamics.

Smoot-Hawley vs. Trump’s Tariffs: Key Comparisons
| Aspect | Smoot-Hawley (1930) | Trump’s Tariffs (2025) |
|---|---|---|
| Economic backdrop | Early Great Depression | Post-high inflation, high interest rates, fragile recovery |
| Tariff scope | 20,000 goods, ~40% average | 10% on all imports + 25–100% on targeted items |
| Trade structure | Relatively domestic-focused | Globalized supply chains, high interdependence |
| Retaliation | Swift, broad retaliatory tariffs | Negotiation-based, selective retaliation |
| Financial system | Gold standard, limited liquidity | Dollar-centered, abundant global liquidity |
A Global Depression Unlikely, But Risks Remain
Today’s world economy is far more complex and resilient than in the 1930s, with built-in stabilizers and institutional safeguards.
Shock Absorbers Compared to the 1930s
- Existence of global institutions (IMF, WTO)
- Growth of digital trade and services
- Stronger fiscal and monetary policy tools
- Diversified supply chains and adaptive multinational corporations
But Warning Signs Are Flashing
- Slower global growth rates
- Rising consumer prices and production costs
- Weaker investor confidence and reduced cross-border investment
- Heightened geopolitical tensions and diplomatic frictions
Conclusion: Learning from History, Facing Today’s Reality
Trump’s tariff strategy bears striking similarities to Smoot-Hawley in its protectionist intent, but today’s global context is very different. A total collapse of world trade and a Great Depression-style meltdown is unlikely. Still, prolonged tariff wars and retaliatory measures could inflict significant pain on both U.S. and global consumers and businesses.
As the saying goes, history does not repeat itself, but it often rhymes. The lesson from the 1930s remains clear: sustainable, balanced trade strategies are vital to maintaining economic stability and preventing short-term political tactics from spiraling into long-term global harm.
