Hedge-fund leader Ken Griffin expressed concerns about Donald Trump’s potential tariff policies, labeling them a “long, slippery slope” that could harm US competitiveness. Speaking at the Oxford Union, he emphasized the need for US businesses to refocus on job creation rather than regulatory struggles. While critical of Trump’s tariffs, Griffin predicts a positive impact on markets under his administration and advocates for reduced government spending. He also voiced reservations about Trump’s mass deportation plans, suggesting a more nuanced immigration policy. Griffin, founder of Citadel, emphasized that investing in talented individuals has been his best strategy for success.
