Global markets and geopolitics shifted sharply under a wave of aggressive U.S. economic and trade actions, anchored by Treasury Secretary Scott Bessent launching Operation Economic Outcast and Economic D-Day maximum sanctions to isolate Iran, driving the Iranian rial to a record low past 2.02 million per U.S. dollar and impacting oil markets. Simultaneously, President Donald Trump announced a 50 percent tariff on cars, trucks, and steel imports from Canada, prompting Canadian Prime Minister Mark Carney to declare his country at war with the United States after trade talks collapsed, while domestic critics like Senator Susan Collins dismissed the duties as a mistake. On the domestic legal front, the U.S. Supreme Court cleared the Trump administration to implement executive order restrictions on mail-in voting by pausing a federal judge's injunction across 23 states, even as ICE agents executed Operation Safe Community to arrest over 1,300 individuals across Maryland and Virginia and Iowa petitioned the Supreme Court to uphold its state immigration law. In the defense and corporate sectors, the U.S. Air Force awarded Boeing a massive $131 billion contract for the F-15 Eagle Weapon System, and technology markets navigated a lower close on chipmaker weakness ahead of Nvidia earnings alongside Amazon's unveiling of its AI-driven Project Tetromino delivery automation initiative, contrasted against routine corporate insider Form 4 filings.
