Wall Street trips as Trump's tariff fans uncertainty

Global stocks on Monday were dragged down by losses on Wall Street and European equities as fresh uncertainty around tariffs intensified after US President Donald Trump announced new levies following a US Supreme Court ruling last week.

Wall Street's main indexes slid, with software and financials being the biggest drags on the benchmarks. Citigroup was down 5.4%, while JPMorgan Chase and Wells Fargo dropped more than 4% each. The Dow Jones Industrial Average fell 1.6%, S& fell 1.2% and Nasdaq Composite fell 1.3%.

The US Supreme Court in a Friday ruling voided most of the tariffs Trump imposed last year. Using a different statute, Trump announced first a 10%, then a 15%, global levy that could last five months while the administration searches for more durable workarounds.

Software-related companies were also among top decliners. The S& Software and Services index was down 3.8%, extending its 23.5% drop this year over AI disruption fears .
