WTI prices surged nearly 10% as the U.S. announced a resumption of maritime blockades against Iran.

President Donald Trump announced on 2026, 7, 14, that the U.S. would resume maritime blockades against vessels traveling to and from Iranian ports and coastal areas in the Strait of Hormuz. Following the announcement, international oil prices surged, with the benchmark WTI rising by nearly 10%.

The U.S. announcement highlighted the renewed risks associated with maritime routes centered around the Strait of Hormuz. The blockaded vessels are specified as those traveling to and from Iranian ports and coasts. Regarding the timing of the announcement, there is still a possibility that the U.S. government may provide additional details on the implementation schedule and scope.

The surge in international oil prices reflects market reactions to uncertainties regarding crude oil transport routes and supply. On that day, oil prices showed a sharp increase during major international trading hours, and the volatility of the global oil market has risen.

As of Korean time, a report has come out indicating that WTI has recorded a rise of approximately two digits in the morning market on 2026, 7, 14. This news triggered fluctuations in stock prices in industries sensitive to oil prices, such as energy, aviation, and shipping.

Details on the implementation of the U.S. lockdown going forward, responses from related countries, and any disruptions in maritime transport are expected to be made public. The possibility of further fluctuations in international oil prices remains a key uncertainty in the market.
