Tue Apr 21 2026 05:39:59 GMT+0000 (Coordinated Universal Time)

Oil prices jumped over 4% after US President Donald Trump announced the seizure of an Iranian cargo ship, foreshadowing potential disruptions in global oil supply.

Global oil prices have surged by over 4% following US President Donald Trump's statement that the US navy intercepted an Iranian cargo ship. The Brent crude benchmark rose to $94.20 a barrel, reversing previous declines amid heightened tensions in the Strait of Hormuz, a critical route for global oil transportation. The market has experienced volatility as the situation between the US and Iran unfolds, including threats from Iran to target vessels near the strait.

Global oil prices have jumped after US President Donald Trump said its navy had intercepted and seized an Iran-flagged cargo ship.

The Brent crude benchmark oil price rose by more than 4% to $94.20 (£69.60) a barrel, reversing a fall on Friday when Iran said the Strait of Hormuz would be completely open to commercial vessels for the remainder of the ceasefire.

On Saturday, Iran said it was closing the strait again and that any ship that approached it would be targeted.

The waterway is of key importance as usually about 20% of the world's oil and liquefied natural gas passes through it.

Energy markets have seen wild swings since the US and Israel attacked Iran on February 28, and Tehran responded with threats to target shipping in the strait.

Trump stated that representatives will be in Pakistan for negotiations, with Vice-President JD Vance leading the US delegation. However, Iranian state media reported that Tehran had no plans for now to participate in the talks, and the position remains unclear.

Analyst Saul Kavonic mentioned that oil markets are reacting more to social media posts than the realities of the situation. With the Strait of Hormuz closed as the Islamic Revolution Guard Corps ended a temporary reopening due to ongoing US blockades, the tension remains high.

Amid these developments, stock markets have experienced mixed results, while Europe reported declines. In contrast, Asian markets saw some gains earlier in the week.

The ongoing conflict has prompted a global energy crisis, impacting supplies and causing a surge in prices. As nations struggle with fuel shortages, the situation in the region continues to evolve, with anxieties over supply stability persisting.
