Oil prices rise as U.S.-Iran talks stall and Strait of Hormuz disruptions continue
The Facts
- Oil prices rose as peace talks between the United States and Iran stalled and disruptions in the Strait of Hormuz continued.
- On April 27, Brent crude traded above $106 a barrel and later settled around $108, while U.S. benchmark WTI traded around $95 to $96 a barrel.
- By April 28, Brent had climbed further toward or above $109 and in some trading moved past $110, while WTI remained below $100.
- Shipments through the Strait of Hormuz remained limited or severely disrupted, constraining global oil supply.
- The Strait of Hormuz is a critical energy chokepoint: sources describe it as carrying about a fifth of the world’s oil and liquefied natural gas, which is why disruptions there affect global markets well beyond the immediate conflict zone.
- The latest price gains followed a sharp weekly rally, with Brent and WTI posting their biggest weekly increases since the war began.
- The diplomatic path remained uncertain after President Donald Trump canceled a planned Islamabad trip by his envoys, though mediator Pakistan said efforts to bridge gaps had not stopped.
- Benchmark prices do not fully capture conditions in the physical oil market during the crisis; one analysis says refiners in some regions were likely paying more than Brent-based headline prices to secure supply.
Context
Why does disruption in the Strait of Hormuz matter so much?
The strait is one of the world’s main energy shipping routes. Sources say about a fifth of global oil and liquefied natural gas flows through it, so reduced traffic there can tighten supply and push up prices worldwide Indian Express,CNBC,CBC News.
Why can benchmark oil prices be misleading during a supply crisis?
Benchmark prices such as Brent are widely quoted, but they may not reflect what refiners actually pay when physical cargoes are scarce. The Indian Express reports that during the Hormuz disruption, buyers in some regions were likely paying more than benchmark prices to keep refineries running Indian Express.
What could happen next?
Markets are watching for any diplomatic progress that could reopen the strait and ease supply pressure. But sources say it is unclear whether the latest Iranian proposal will lead to de-escalation, and analysts cited by CNBC say even if hostilities ended immediately, returning to normal market conditions could take months Investing.com,CNBC.
How left and right read it
What stands out is how a disruption at a single chokepoint can ripple far beyond the conflict zone, because the Strait of Hormuz carries about a fifth of the world’s oil and liquefied natural gas. The benchmark numbers are important, but fact 8 matters just as much: in some regions, refiners were likely paying even more than Brent-based headline prices to secure supply.
The key issue is strategic vulnerability: when shipments through the Strait of Hormuz are limited, a critical global energy route can constrain supply and drive sharp price moves. This story also cautions against overreading headline benchmarks alone, since the physical market can diverge during a crisis and expose how stressed actual supply conditions are.
