TLDR
- UAE is leaving OPEC effective Friday, freeing it to raise oil production beyond cartel quotas
- President Trump has told aides to prepare for a prolonged blockade of Iranian ports
- Brent crude rose over 3% to $114.93 a barrel; WTI gained 3.8% to $103.65 a barrel
- Peace talks between the U.S. and Iran have stalled, with no reopening of the Strait of Hormuz in sight
- One-fifth of the world’s oil passes through the Strait of Hormuz, keeping supply concerns elevated
Oil prices jumped sharply on Wednesday as two major developments rattled energy markets: the United Arab Emirates announced it is leaving OPEC, and reports emerged that President Trump is preparing for an extended blockade of Iran.
Brent crude, the global benchmark, rose 3.3% to $114.93 a barrel. U.S. West Texas Intermediate crude climbed 3.8% to $103.65 a barrel.

The UAE said its exit from OPEC, effective Friday, would let the country focus on its “national interests.” The UAE has clashed with OPEC over output quotas in the past and is widely expected to boost production once it is no longer bound by them.
The departure puts the UAE at odds with Saudi Arabia, OPEC’s de facto leader, at a time when the group is already under pressure from the ongoing Iran war and supply disruptions.
However, any production increase from the UAE will likely be limited until the Strait of Hormuz reopens. The narrow waterway off Iran’s southern coast carries roughly one-fifth of the world’s oil supply and is currently seeing near-zero traffic.
Blockade Fears Push Prices Higher
The Wall Street Journal reported Tuesday that Trump has directed aides to plan for a prolonged blockade of Iranian ports. The move is designed to choke Iran’s oil exports and pressure Tehran into a new deal.
"Iran has just informed us that they are in a “State of Collapse.” They want us to “Open the Hormuz Strait,” as soon as possible, as they try to figure out their leadership situation (Which I believe they will be able to do!)." – President Donald J. Trump 🇺🇸 pic.twitter.com/XKSQRRRDRh

Trump has also rejected an Iranian proposal to reopen the Strait and end the conflict. Washington is demanding stricter limits on Iran’s nuclear program before any agreement.
Iran has called for the blockade to be lifted before peace talks can begin. While Trump extended a ceasefire with Iran indefinitely last week, efforts to bring both sides to the negotiating table have so far failed.
Analysts at ANZ said stalled peace talks have raised the prospect of an indefinite disruption to Persian Gulf oil supplies. They added that rebalancing the market after the Strait reopens “will take years.”
What Analysts Are Saying
Some analysts see the UAE’s exit as part of a longer-term shift in oil markets. Julius Baer analyst Norbert Rücker said the real challenge for oil-producing nations is broader competition from U.S. shale, South American deepwater oil, and the rise of Chinese hybrid vehicles. He sees prices anchored in the high $60s per barrel in the long run.
Capital Economics suggested the UAE’s moves may signal a deeper alignment with the U.S. and Israel. The country was an early signatory to the Abraham Accords and has pledged major AI-related investments in the U.S.
Earlier this month, the UAE opened talks with Washington about a potential currency swap line, citing concerns over the economic impact of the Iran war.
Traders are now watching for updates on peace negotiations and this week’s U.S. crude inventory report for clues on how fast stockpiles are declining.
