Oil prices rise above $100 amid Hormuz closure

Oil prices rose 1% on Tuesday, April 28, 2026, ‌as efforts to end the United States-Iran war appear stalled, with the crucial Strait of Hormuz waterway still mainly shut.

A United States official disclosed on Monday that President Donald Trump is unhappy with the latest Iranian ​proposal aimed at ending the war.

Iranian sources revealed on Monday that Tehran’s ​proposal avoided addressing its nuclear programme until hostilities cease and Gulf shipping disputes are resolved.

Trump’s ⁠displeasure with the Iranian offer leaves the conflict deadlocked, with Iran shutting shipping flows through the Strait of ​Hormuz, which typically carries supply equal to about 20% of global oil and gas consumption, and the U.S. keeping ​in place its blockade of Iranian ports.

Brent crude futures for June climbed $1.41, or 1.3%, to $109.64 a barrel as of 0400 GMT, after gaining 2.8% in the previous session to its highest close since April 7. The contract is up for a seventh day.

U.S. ​West Texas Intermediate (WTI) crude for June rose $1.27, or 1.3%, to $97.64 a barrel, after gaining 2.1% in the previous session.

An ​earlier round of negotiations between the U.S. and Iran collapsed last week following failed face-to-face talks.

Phillip Nova’s senior market analyst Priyanka Sachdeva told Reuters: “Talks around ‘peace’ still look largely superficial and ‌lack ⁠concrete evidence of de-escalation. Despite the rhetoric, vessel movement through the Strait of Hormuz remains curtailed, and that prolonged disruption is what’s keeping oil risk premiums elevated.

“In the near term, oil markets are less about macro demand and more about diplomatic gridlock. Until diplomacy translates into actual barrel flows, not ​just statements, oil markets ​will remain volatile with an ⁠upward bias through May.”

Ship-tracking data revealed significant disruptions in the region, with six Iranian oil tankers forced to turn back due to the U.S. blockade.
