Trump imposed tariffs last year in April 2025 when Mercury was retrograde.
The US Supreme Court ruled on 20 February 2026 that these were unconstitutional as Saturn and Neptune were exactly conjunct.
A few hours after the court’s decision, Trump announced across-the-board tariffs of 10 percent, and the next day boosted those to 15 percent—their maximum level. They expire after 150 days unless extended by Congress.
Mercury is currently retrograde again – starting on 26 February until 20 March 2026.
