A new model calculated the impact of President Donald Trump's ‘Liberation Day’ tariffs on US households and the country's GDP. Designed by The Conversation's Steven Vass, the model concluded that if other countries hit Washington with equivalent tariffs, the US GDP would take a massive $438.4 billion (1.45%) hit.

Last week, President Trump announced reciprocal tariffs on several trade partners with the minimum baseline for each country at 10%. As per the White House's tariff chart, Vietnam will take a 46% tariff hit, Thailand is at 36%, China at 34%, Indonesia pays 32%, Taiwan at 32% and Switzerland at 31%. Beijing's 34% hit is in addition to an existing 20% tariff - taking the number to 54%.

While Canada and Mexico were exempted from the reciprocal tariffs under the USMCA, certain goods from them are subject to a 25% tariff as per Trump's executive order
The Conversation's Steven Vass calculated the impact of these tariffs on US households by using two scenarios- if countries retaliate in equivalent measures and if they don't. The report stated that the author used a ‘global model of the production, trade, and consumption of goods and services’.

In the second scenario, Steven Vass states, that the tariffs decrease the United States' GDP by $149 billion (0.49%). “Aggregate GDP for the rest of the world decreases by $155 billion, more than twice the corresponding decrease when there was retaliation,” the report further adds.
