US equity markets faced renewed 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 signals a broadening of trade policy risks beyond existing measures, raising concerns about further supply chain disruptions and cost inflation across global sectors.

The market reaction underscores the growing financial strain caused by US tariffs, a theme that has already impacted major multinationals.

Philips and Pandora recently announced their intention to apply for tariff rebates following the first-quarter earnings season, highlighting the tangible cost pressures facing companies exposed to US trade barriers.

These corporate responses indicate that the burden of tariffs is increasingly being passed through to balance sheets, with firms seeking relief mechanisms to mitigate margin erosion.

The sheer range of tariffs and duties under consideration is extensive, affecting a wide array of consumer goods and industrial inputs.
