US equity markets faced fresh selling pressure on Thursday as investors digested reports that the Trump administration is preparing to announce a significant expansion of tariffs targeting dozens of countries.

The development has triggered a wave of corporate lobbying in Washington, with companies ramping up spending to influence the trajectory of trade policy.

The surge in lobbying activity underscores the growing urgency among businesses to navigate an increasingly aggressive tariff regime.

As the administration moves to broaden its trade restrictions, firms across multiple sectors are seeking to mitigate potential costs and supply chain disruptions.

This intensifying political engagement reflects the high stakes involved in the evolving trade landscape.

Market participants are closely monitoring the situation, with the prospect of wider tariffs adding to existing uncertainties.
