Oil Surges 10% as Trump Blockades Iran and Claims Hormuz Control

Summarized from Forexlive

Trump announced a full Iran blockade and a 20% Hormuz shipping toll, sending oil nearly 10% higher while stocks and bonds sold off sharply.

President Trump escalated confrontation with Iran on Wednesday, announcing a total naval blockade, claiming U.S. control of the Strait of Hormuz, and imposing a 20% toll on all goods transiting the critical waterway — moves that immediately rattled global markets and drove crude oil prices sharply higher. The U.S. Navy confirmed it would enforce the blockade, and a fresh round of strikes targeted commercial ships near Iran, echoing the tensions that gripped markets in April.

WTI crude oil surged nearly 10%, settling up $6.24 at $77.64 per barrel before trimming some gains into the close. The sweeping maritime actions left traders bracing for further disruption to energy flows, and Trump signaled he would deliver a speech Thursday evening that could lay out plans for a more extended campaign. Gold fell $121 to $3,998 as the U.S. dollar dominated currency markets, with the Australian dollar the session's weakest performer.

Equity markets bore the brunt of the dual shocks. The S&P 500 fell 0.8% and the Nasdaq dropped 1.7%, with semiconductor stocks leading declines — Micron shed 4.9% and Intel tumbled nearly 7%. U.S. 2-year Treasury yields climbed 5.7 basis points to 4.26%, the highest level since February 2025, while the long end also sold off as inflation fears deepened. USD/JPY rose steadily but stalled near 162.50 amid lingering intervention risk from Japanese authorities.

The June federal budget deficit came in at $120 billion, narrower than the $138 billion consensus estimate, though the figure drew little market attention amid the geopolitical storm. With bank earnings kicking off Thursday, investors face a packed calendar that could either stabilize or intensify the day's jarring moves. Continue reading at Forexlive.
