Former President Trump's proposed tariff hikes are creating fresh uncertainty for Wall Street firms already grappling with volatile markets. His 'shock regime' approach targets imported goods with steep duties, potentially disrupting supply chains and corporate profit margins across multiple sectors.

JPMorgan faces a separate legal headache after Trump filed suit alleging the bank defrauded his business empire. The lawsuit adds to ongoing regulatory scrutiny of major financial institutions. Meanwhile, crypto hardware wallet maker Ledger is preparing a ambitious $4 billion US listing, seeking capital amid market turbulence.

Investors are watching closely as trade policy uncertainty combines with existing economic headwinds. Corporate treasurers may need to reassess hedging strategies if Trump's tariff threats materialize. Markets could face renewed volatility ahead of any policy announcements.

Banking executives worry about mounting legal risks under potential future administrations. Companies reliant on imported goods are quietly reviewing exposure to proposed tariff structures.
