[Former U.S. Treasury Secretary Summers: Tariff Policy Could Trigger a Severe Financial Crisis in the U.S.] On April 9, former U.S. Treasury Secretary Summers wrote on social media: "The developments in the past 24 hours suggest that we may be heading towards a severe financial crisis entirely triggered by the U.S. government's tariff policy. Given the government debt and deficits, as well as dependence on foreign buyers, this could lead to various vicious cycles. The only way to mitigate these risks is for President Trump to abandon the current course. This is the first round of financial turmoil triggered by the U.S. government."
