Oil Prices Spike as Iran Closes Strait of Hormuz and Ceasefire Nears Expiration

STRAIT OF HORMUZ — Global energy markets were thrown into fresh volatility on Sunday as oil prices surged following Iran’s decision to once again block the Strait of Hormuz. The move, which affects a waterway responsible for one-fifth of the world’s crude oil, comes at a critical moment as a regional ceasefire nears its expiration.

Brent crude, the international benchmark, jumped roughly 7 percent to $96.88 per barrel. This spike follows a brief period of lower prices on Friday when reports suggested the strait might remain open. U.S. crude similarly rose 7 percent, reaching $90.33. The closure has significantly disrupted shipping, with tracking data confirming that no tankers successfully crossed the strait on Sunday.

The escalation turned physical on Saturday and Sunday when Iranian gunboats reportedly fired on tankers attempting to transit the area. In response, President Donald Trump characterized the actions as a "violation" of the standing ceasefire. By Sunday, the U.S. military engaged an Iranian-flagged ship, the "Touska," which was allegedly attempting to breach a U.S. naval blockade. U.S. Central Command confirmed the vessel was seized after the military fired "several rounds" to disable it.

The Iranian military has since warned of retaliation, labeling the seizure as "U.S. armed piracy" through state-run media. The rising military tension has cast a shadow over upcoming peace talks scheduled to take place in Islamabad, Pakistan. While a U.S. delegation is en route, and Iranian negotiators are expected to arrive Tuesday, Tehran has not yet publicly confirmed its official attendance.

The impact of the conflict is being felt directly at the pump for American consumers. U.S. gas prices reached a national average of $4.05 per gallon on Sunday. Energy Secretary Chris Wright stated that while a return to prices under $3 per gallon is possible later this year, it is more likely that such relief will not arrive until 2027, depending on the stability of the global energy market.

Financial markets have reacted sharply to the news, with Dow, S&P 500, and Nasdaq futures all trading down roughly 0.8 to 0.9 percent. With the ceasefire set to expire this Wednesday, April 22, the international community remains focused on whether a diplomatic agreement can be reached before the deadline.
