Aston Business School warns Trump’s reciprocal tariff war could shrink US GDP by 1.3%, spike domestic prices by 5.5%, and erase $1.4 trillion in global economic activity.
Donald Trump’s upcoming tariff rollout could unleash a global trade war, slashing $1.4 trillion from the world economy, hurting US consumers with rising prices, and pulling the country closer to recession, warns a new UK study.
Trump’s Trade Tsunami: How ‘Liberation Day’ Tariffs Could Wreck the Global Economy
Donald Trump is about to launch what he calls “Liberation Day”—but economists are sounding the alarm that it may resemble an economic reckoning instead.
Set to begin on Wednesday, April 2, Trump’s reciprocal tariff war could trigger a full-scale economic backlash that costs the global economy $1.4 trillion and raises prices in the US by more than 5.5%, according to a bombshell analysis by Aston Business School in the UK. Far from liberating anyone, the tariffs are now being called a gateway to global disruption.
Trump’s message is clear: America will not be taken advantage of. But the cost of that defiance, economists warn, may be dangerously high. Consumer sentiment in the US is already at a four-year low, the stock market is rattled, and inflationary pressure is climbing fast. The Aston study also estimates that America’s own GDP could contract by 1.3%—a self-inflicted wound that could tip the economy toward recession.
The centerpiece of Trump’s plan is reciprocal tariffs—a retaliatory tax on goods from countries that impose higher import duties on US products. While politically popular with segments of his base, the real-world consequence is a likely global trade war. Allies and adversaries alike are expected to respond in kind, triggering a cascading spiral of tit-for-tat levies that disrupt global supply chains and fracture markets.
Even Trump’s economic cheerleaders are beginning to squirm. The promise of “America First” is colliding head-on with America Pays More, as rising costs on imported essentials—from electronics to autos to food—begin to filter down to everyday consumers.
This isn’t just theoretical. The Aston model echoes 1930s-style trade barriers that exacerbated the Great Depression. The analysis warns that global economies, still reeling from COVID-era disruptions and ongoing wars, are far more fragile than they appear.
As Trump frames the tariffs as an act of national self-respect, critics say the world may remember April 2 not as Liberation Day—but as Isolation Day.
In the end, economic nationalism comes with a price tag—and this one might just bankrupt the very system it’s trying to protect.
