US Stocks Dip on Renewed Tariff Uncertainty
23 Feb
Summary
- New tariff uncertainty emerged after a Supreme Court ruling.
- President Trump announced a new 15% duty using a different statute.
- Markets experienced volatility due to planning challenges for businesses.

U.S. stock index futures saw a dip on Monday, February 23, 2026, due to renewed tariff uncertainty. This came after President Donald Trump announced a new 15% global levy, despite a Supreme Court ruling on Friday, February 20, 2026, that had voided most of his previously imposed tariffs. The administration is now seeking workarounds using a different statute for these new duties.
This evolving tariff landscape has created significant planning challenges for businesses concerning suppliers and supply chains. Arthur Laffer Jr. highlighted that this uncertainty is a major concern for corporate America, emphasizing the need for clarity to enable effective planning. While the main stock indexes achieved weekly gains by Friday, February 20, the ongoing tariff concerns are now weighing on premarket trading.
