President Donald Trump’s recent tariff policies have even made his billionaire backers squirm. Hedge fund manager Bill Ackman, who lent his support to Trump before the 2024 presidential election, said the president should take three months to allow countries to renegotiate their trading relationships with the U.S. He added that not doing so could risk “a self-induced, economic nuclear winter.”
Trump’s escalating tariff wars with China and other trade partners have caused the stock market to spiral with even the “Magnificent 7” being hit. Goldman Sachs recently increased its odds for a recession in the U.S. economy to 45% while other Wall Street heavyweights like J.P. Morgan has raised the odds even higher with a 60% prediction of another recession hitting the U.S.
Despite the shockwaves in the economy and the markets, Trump has defended his new import taxes, saying “sometimes you have to take medicine to fix something.”

A 2025 U.S. recession with high tariffs on China, Canada, and other trade partners could lead to reduced trade volumes. High tariffs would make imports more expensive, decreasing consumer demand for foreign goods and disrupting supply chains. U.S. exports may also decline as tariffs make American products less competitive. The retaliation by China, Canada, and other partners could further strain trade relations.
Companies may shift production to countries with lower tariffs, leading to job losses in the U.S. and potential shifts in global supply chains. The overall effect would be slower economic recovery and increased global trade tensions.
Ackman, the billionaire founder of Pershing Square hedge fund management company, reportedly became a high-profile supporter of Trump, a Republican, in July 2024, while he had previously backed the rival Democratic Party.
