Crude Oil Prices Surge on U.S. Seizure of Iranian Vessel: Brent Up 5%, WTI Up 6%

Gate News message, April 20 — Crude oil prices jumped sharply yesterday (April 19) after U.S. forces seized an Iranian-flagged cargo vessel in the Gulf of Oman. Brent crude climbed over 5% to above $95 per barrel, while WTI (West Texas Intermediate) rose more than 6% toward $89 per barrel as of writing. The rebound followed President Donald Trump’s confirmation that U.S. Marines boarded the Iranian ship after it ignored orders to stop while exiting the Strait of Hormuz.

The seizure marked the first known use of force under the current U.S. blockade strategy and immediately raised supply disruption concerns. Iran responded by signaling it could tighten control over the Strait of Hormuz—one of the world’s most critical oil shipping chokepoints—and restrict transit until the U.S. lifts its blockade on Iranian ports. Tehran also accused Washington of violating the ceasefire agreement, claiming the blockade disrupted agreed terms. Despite escalating tensions, President Trump stated that U.S. negotiators would travel to Pakistan for another round of talks with Iranian officials, though Iran has not confirmed participation and state media suggested officials may skip the discussions.

Analysts warn of growing risks of a prolonged energy supply shock if disruptions continue. Higher energy costs could intensify global inflation pressures across transportation and manufacturing sectors. U.S. stock futures also edged lower following the developments, signaling broader market concern over renewed uncertainty.
