KIEL, Germany (IFW Kiel) — protectionist trade policies and currency manipulation can have devastating consequences, according to a new Kiel Policy letter examining the economic crisis of the 1930s. The analysis draws parallels between the trade wars of the past and current international trade tensions.
The study, released May 5, 2025, by the Kiel Institute for the World Economy (IFW Kiel), highlights the dangers of countries engaging in retaliatory tariffs and currency devaluation, actions that exacerbated the global economic downturn nearly a century ago.
The report challenges the notion that trade wars are easily won, a sentiment echoed by some policymakers. “Our analyses on the ‘mother of all trade wars’ – the one that the United States turned in 1930 with the adoption of the Smoot-Hawley Tariff – show that it was not only harmful to the U.S.,” the report states, referencing their study titled “Commercial and monetary wars- teaching from history”.
Researchers based their findings on a complete quarterly panel dataset encompassing bilateral trade flows from 1925 to 1938. The dataset includes information from 99 countries, colonies, and country groups, comprising over 108,000 observations and covering a meaningful portion of global trade during that period.
Key U.S. Exports Hit Hardest
The U.S.Customs Act of 1930, initially intended to aid struggling farmers, evolved into a broad revision of U.S. customs law. In response, major U.S.trading partners imposed retaliatory tariffs,import restrictions,and boycotts on American goods.
U.S. exports to countries that retaliated fell by as much as 33%, the study found. Even countries that only threatened retaliation saw a decrease in U.S. exports of up to 22%. The decline was particularly noticeable in key American export sectors, such as automobiles and agricultural products.
Trade and Currency Conflicts Intertwined
The global economic crisis prompted many nations to abandon the international gold standard, leading to widespread currency devaluations. Between 1929 and 1936, over 70 countries devalued their currencies against gold, further disrupting international trade. The analysis suggests that a country’s trade decreased by more than 21% following a devaluation.
Europe’s Opportunity to lead
The authors of the Kiel Policy letter argue that recent trade policies signal a departure from the United States’ long-held leadership role in the global trading system.
“In order to avoid the mistakes of the 1930s, Europe has to fill the global leadership vacuum left by the USA,”
— Mitschener, Kiel Institute for the World Economy
The report suggests that Europe should project stability and promote the euro as a safe haven for investors, particularly as China seeks to elevate the Renminbi as an international trade, credit, and reserve currency.

Trade Wars: Lessons from the 1930s Economic Crisis – Your Essential Q&A Guide
What were the key findings of the Kiel Institute for the World Economy’s study on trade wars?
The Kiel Institute for the World Economy (IFW Kiel) released a report examining the economic crisis of the 1930s, focusing on the devastating consequences of protectionist trade policies and currency manipulation. The study draws parallels between historical trade wars and current international trade tensions. A key finding is that countries engaging in retaliatory tariffs and currency devaluation exacerbated the global economic downturn nearly a century ago.The report also challenges the notion that trade wars are easily won.
What specific historical event did the Kiel Institute study focus on?
The study specifically references the “mother of all trade wars” – the one initiated by the United States with the adoption of the Smoot-Hawley Tariff in 1930.
What was the Smoot-Hawley Tariff, and why is it significant?
The Smoot-Hawley Tariff, implemented in 1930, was a broad revision of U.S. customs law.initially intended to help struggling farmers, it lead to major U.S. trading partners imposing retaliatory tariffs, import restrictions, and boycotts on American goods. This event is significant because it serves as a historical example of how protectionist policies can backfire, leading to a decline in international trade and contributing to economic hardship.
How did retaliatory tariffs impact U.S. exports?
The study found that U.S. exports to countries that retaliated against the Smoot-Hawley Tariff fell by as much as 33%.Even countries that only threatened retaliation saw a decrease in U.S. exports of up to 22%. This decline was especially noticeable in key American export sectors, such as automobiles and agricultural products.
What role did currency devaluation play in the economic crisis of the 1930s?
The economic crisis of the 1930s prompted many nations to abandon the international gold standard, leading to widespread currency devaluations. Between 1929 and 1936, over 70 countries devalued their currencies against gold. The analysis suggests that a country’s trade decreased by more than 21% following a devaluation.
what were the main factors contributing to the trade decline?
Based on the source material, the main factors contributing to the trade decline were:
Retaliatory Tariffs: Imposed by other countries in response to the U.S. Smoot-Hawley Tariff.
Import Restrictions: Further measures other countries implemented.
Boycotts: actions taken against American goods.
Currency Devaluations: Widespread abandonment of the gold standard and currency manipulation.
Can you summarize the impact of trade wars using a historical example?
Certainly. The U.S.Customs Act of 1930, known as the Smoot-Hawley Tariff, was initially intended to help struggling farmers, but it led to a series of negative consequences:
Retaliation: Major U.S. trading partners responded with tariffs, restrictions, and boycotts.
Export Decline: U.S. exports dropped significantly, with declines of up to 33% to retaliating countries and up to 22% to those merely threatening to retaliate. this was especially hard on key American export sectors, like automobiles and agriculture, worsening economic conditions.
Broader Economic Hardship: The global economic downturn and the decline in international trade, further worsened the situation.
What does the Kiel Institute’s report suggest about current trade policies?
The report suggests that recent trade policies signal a departure from the United States’ long-held leadership role in the global trading system.
What role does the report suggest Europe should play?
The report suggests that Europe should fill the global leadership vacuum left by the USA. It proposes that Europe should project stability and promote the euro as a safe haven for investors, especially as China seeks to elevate the Renminbi as an international trade, credit, and reserve currency.
What are the potential long-term consequences of trade wars and currency manipulation?
Based on the Kiel Institute’s analysis of the 1930s, potential long-term consequences include:
Economic Downturns: Retaliatory tariffs and currency devaluations exacerbate global economic downturns.
Decreased Trade: Protectionist measures can significantly reduce international trade volumes.
Damage to Key Sectors: specific industries, like automobiles and agriculture, can be severely impacted.
Loss of Leadership: Shifts in the global trade landscape and leadership roles.
Currency Instability: Currency manipulation can disrupt international trade and financial markets.
How can the mistakes of the 1930s be avoided in today’s world?
According to the Kiel Institute, one key step is for Europe to fill the global leadership vacuum left by the USA, promoting stability and a strong currency. Avoiding protectionist trade policies and currency manipulation is crucial.
