Oil Prices Jump as Iran Attacks Ships — and the US Strikes Back
Oil prices spiked on July 8, 2026, rising roughly 5 to 6 percent, after Iran attacked commercial ships carrying fuel through one of the world's most critical waterways The Guardian. Brent crude — a global benchmark for oil prices — hit $78 per barrel, its highest point since the US and Iran agreed to a ceasefire just weeks earlier CNBC.
What Happened
On July 7, Iran's military fired missiles at three fuel tankers in the Strait of Hormuz, a narrow waterway between Iran and Oman that carries roughly one-fifth of the world's traded oil Reuters. One of the vessels was a Qatari ship carrying liquefied natural gas — a highly flammable cargo that was left at serious risk The New York Times. Iran's state television said the LNG carrier was hit after "ignoring warnings," though Iranian officials stopped short of directly claiming responsibility NPR.
The U.S. responded swiftly. The military's Central Command (CENTCOM) confirmed that American forces struck Iranian targets on July 7 CBS News. President Donald Trump declared that the ceasefire agreement — signed just weeks earlier in June — was "over" BBC. The U.S. Treasury also revoked Iran's license to sell oil internationally Reuters.
Why This Matters for Global Energy
Ships are now avoiding the Strait of Hormuz. At least four tankers carrying oil and gas reversed course rather than risk the journey, according to ship-tracking data The Guardian. Analysts say traffic through the waterway has "essentially stopped," and maritime authorities raised the risk classification to "severe" Reuters. That matters because the Strait is how roughly one-fifth of the world's oil gets from the Middle East to everywhere else.
The ripple effects are already visible. Natural gas prices in Europe climbed 5 percent, since Europe relies on liquefied natural gas shipped through that same waterway The Guardian.
The Bigger Picture
This is not the first disruption to shipping through the Strait this year. A partial blockade began in March 2026, and during the worst phase of the US-Iran conflict — which started in late February — roughly 20 million barrels of oil a day stopped flowing from Gulf producers White House. Oil prices at that point reached above $110 per barrel, far higher than the $78 level we see this week.
The current conflict goes by the name Operation Epic Fury, a term the White House began using in March and April White House. Trump first announced a two-week ceasefire via social media in reference to a "10-point proposal," calling it "a double sided CEASEFIRE" Truth Social. That informal agreement gave way in June to a more formal written agreement signed by Trump and Vice President JD Vance. That document is what Trump now says is finished.
The ceasefire had already shown signs of strain before this week. On June 27, a Panama-flagged oil tanker carrying more than two million barrels was attacked near the Strait CENTCOM, and U.S. forces separately disabled an Iranian cargo ship attempting to break through a naval blockade in the Gulf of Oman. The U.S. military also held a regional security meeting with 12 nations in Bahrain on July 1 — diplomatic preparation that the events of July 7 have overtaken.
What Comes Next
The fate of the ceasefire will likely depend on a simple measure: whether ships resume traveling through the Strait of Hormuz in the coming days. If traffic stays blocked for an extended period, the impact will spread beyond just higher oil prices. Asia and Europe both depend heavily on liquefied natural gas arriving by ship through this same corridor.
For now, markets are treating this as a serious risk spike rather than a return to the worst-case scenario. Oil at $78 is notably lower than the $110 peak in May, which tells us that traders believe there is still some possibility the shipping freeze will end. But the events of the next 48 hours will likely decide whether that optimism holds.
There is one more factor at play. Iran's Supreme Leader, Ayatollah Ali Khamenei, is undergoing a leadership transition — his burial ceremony is scheduled for later this week — and the full implications of that shift for how Iran makes decisions in a crisis are not yet clear from public reporting.
