Key Takeaways:
Explosions near Iran's Bushehr nuclear plant sent crude prices up 2.5% Thursday as the fragile US-Iran ceasefire showed signs of collapse.
Iranian state media reported blasts in Bushehr, home to the Islamic Republic's primary nuclear power plant, without providing an immediate cause or damage assessment. The incident came hours after Iran's Islamic Revolutionary Guard Corps said it launched retaliatory strikes on an American military base following what it described as a US aerial attack near Bandar Abbas Airport, according to Tasnim News Agency.
"The situation on the ground is deteriorating faster than diplomatic channels can contain it, and the risk premium in oil markets is repricing accordingly," said Elena Fischer, geopolitical risk analyst at Edgen. "Every escalation near Iran's nuclear infrastructure or the Strait of Hormuz carries outsized consequences for global energy supply."
Brent crude rose roughly $2.50 to trade near $87 a barrel, partially reversing Wednesday's decline that had been driven by hopes of a diplomatic breakthrough. The US dollar index fell 0.29% to 99.02 after Axios reported that US and Iranian negotiators had agreed on a 60-day memorandum of understanding to extend the ceasefire and launch nuclear talks — though the deal still requires President Donald Trump's approval. Gold edged higher as investors rotated into safe-haven assets, while Asian equity markets sold off on risk-aversion.
The Strait of Hormuz handles about 20% of the world's oil and gas flows, and the waterway has been effectively closed to commercial shipping since the US-Israeli war on Iran began on Feb. 28. The reported MOU would require Iran to remove all mines within 30 days and commit to not pursuing a nuclear weapon, while the US would lift its naval blockade on Iranian ports in proportion to restored commercial shipping. But Thursday's exchange of fire — including Iran's missile launch toward Kuwait, which Kuwaiti air defenses intercepted — underscored how quickly the ceasefire could unravel.
Nuclear risk and the energy premium
Bushehr's nuclear reactor adds a layer of concern beyond oil infrastructure. Any damage or disruption at the facility could trigger a broader humanitarian and environmental crisis in the Persian Gulf, while also raising questions about Iran's nuclear program at a moment when Washington and Tehran are ostensibly negotiating its future. The International Atomic Energy Agency has not yet commented on the reported explosions.
The US Treasury Department announced fresh sanctions on Iran's military oil trade Thursday, targeting eight vessels involved in transporting Iranian crude, even as diplomatic channels remained active. Treasury Secretary Scott Bessent also warned Oman against facilitating any tolling system for the Strait of Hormuz, saying the US would "aggressively" target any actors involved.
What comes next
The 60-day MOU, if approved by Trump, would represent the most significant diplomatic framework between Washington and Tehran since the 2015 nuclear deal. But the president said Wednesday he was "not satisfied" with Iran's offers and warned he could "finish the job" militarily. Iran's supreme leader, Ayatollah Mojtaba Khamenei, said the US and Israel were seeking to "bring the nation to its knees," according to state television.
The IEA said Thursday that the US-Israeli war on Iran is reshaping global energy strategies, calling it "the largest energy security crisis the world has ever faced." Oil investment is expected to fall below $500 billion in 2026 for the third straight year despite rising crude prices, as uncertainty over how long higher prices will last limits new spending.
