Trump's tariffs are likely illegal, says Piper Sandler's Andy Laperriere

Trade Policy & Legal Challenges - A federal appeals court is hearing arguments about whether President Trump overstepped his authority to impose tariffs, potentially rendering trade deals illegal [1] - Piper Sandler suggests the administration is struggling to justify the tariffs, arguing the President is claiming national emergency powers without statutory authority [2][3] - The legality of tariffs is questioned, citing Article 1, Section 8 of the Constitution, which grants Congress the authority to impose tariffs [4][5] - The case is likely headed to the Supreme Court, with potential rulings in the coming months and a decision possibly by June [6][7] - There is a possibility that the Supreme Court may strike down the tariffs, with originalist and liberal judges potentially aligning against broad presidential authority [7][8][9] Market Impact & Investor Sentiment - The market's reaction to a potential overturning of trade deals is uncertain, with investors seemingly unconcerned about the tariffs [10][11] - The market consensus appears to be that the worst of the tariffs is over, but this view is challenged as deals are raising, not lowering, tariffs [11][12][13]
