PARIS, Aug 8, 2025 (BSS/AFP) - The US tariff rate now averages 20.1 percent, the highest level since the early 1910s -- except for a brief spike earlier this year -- after new duties took effect Thursday, WTO and IMF data showed Friday.

The figure, calculated by the World Trade Organization (WTO) and the International Monetary Fund (IMF), stands in contrast with the 2.4 percent rate in force at the time of President Donald Trump's inauguration on January 20.

Trump's April 2 announcement of "reciprocal" tariffs on the United States' main trading partners and subsequent escalations, particularly on Chinese goods, briefly drove the average rate to 24.8 percent in May, a figure unseen since 1904, according to data from the United States International Trade Commission.

A trade "truce" brought down sky-high tariff levels that the United States and China had imposed upon one another, but that is set to expire next week.

The new figure by the WTO and IMF takes into account the trade deals the United States negotiated with the European Union, Japan, South Korea and other nations that have now come into force.

These deals usually included lower tariff levels than Trump threatened in April, but were higher than the baseline 10 percent rate the US introduced.

The rate calculated by the WTO and the IMF applies the latest rates to 2024 trade volumes.

The updated average tariff rate exceeds the nearly 20 percent rate that the United States applied in the 1930s, a period of high tariffs that economists widely consider behind the severity and duration of the Great Depression.
