<h1>Trump 'Liberation Day' tariffs legality and Venezuela-sanctions oil tanker seizures drive trade-cost exposure, with enforceability still uncertain.</h1> Markets anticipated a possible Supreme Court ruling on the legality of President Trump's 'Liberation Day' tariffs, with any decision expected to determine whether the tariff measures remain enforceable or are curtailed, thereby affecting trade-cost exposure and investor sentiment. Separately, the United States reportedly intensified enforcement actions targeting sanctioned oil movements linked to Venezuela by seizing additional oil tankers, including a vessel alleged to have evaded a blockade on sanctioned oil vessels, with the operative effect of restricting maritime transport of oil and heightening supply disruption risk in energy markets.
