Global oil markets moved lower after signs emerged that diplomatic efforts to restore shipping through the Strait of Hormuz were making progress. The optimism came even as US President Donald Trump warned Iran that it would face severe consequences if the crucial maritime route remained closed.
The Strait of Hormuz is one of the world’s busiest energy corridors, and any disruption there has an immediate impact on global oil supplies and fuel prices.
Trump Expects Strait to Reopen Soon
Speaking during his visit to California, Donald Trump expressed confidence that commercial shipping through the Strait of Hormuz would resume shortly.
He warned that Iran would be “hit very hard” if the waterway failed to reopen in the near future. Trump also said discussions aimed at easing the crisis were progressing positively and suggested that all sides wanted to reach a solution.
Diplomatic Talks Raise Market Optimism
Senior US officials also indicated that negotiations had moved forward.
Secretary of State Marco Rubio said meaningful progress had been made, although no final agreement had been reached. Treasury Secretary Scott Bessent added that an agreement could be finalised soon if discussions continued in the current direction.
Neither official revealed the details of the proposed arrangement, but both expressed confidence that commercial vessels could soon resume normal movement through the strategic waterway.
Crude Oil Prices Extend Their Decline
The possibility of a diplomatic breakthrough eased concerns over global oil supplies.
Brent crude, the international oil benchmark, fell by nearly 5% on Tuesday, slipping below $80 per barrel for the first time in almost three weeks. Prices continued to decline during Wednesday’s Asian trading session.
US West Texas Intermediate (WTI) crude also dropped by more than 5%, reaching around $76 per barrel, as traders anticipated improved supply conditions.
Iran Says It Is Working Through Oman
While US officials spoke about progress, Iran maintained that it was not holding direct negotiations with Washington.
Iran’s Foreign Ministry said discussions were taking place only with Oman, which is acting as a mediator. Officials described those talks as constructive but stopped short of confirming that an agreement was close.
Meanwhile, Qatar said it was continuing diplomatic efforts with regional partners, although no direct US-Iran talks were currently planned.
Why the Strait of Hormuz Matters
The Strait of Hormuz plays a critical role in global energy trade.
Before the latest conflict disrupted shipping, the route handled nearly 20% of the world’s daily oil and liquefied natural gas (LNG) exports. Any interruption to traffic through the narrow waterway can quickly push up crude oil prices and increase fuel costs around the world.
US Central Command (CENTCOM) said the southern shipping lane through the Strait remains open for commercial vessels using international waters.
Security Concerns Continue Across the Region
Despite growing optimism over negotiations, regional security remains fragile.
Iran has restricted much of the commercial traffic through the Strait since tensions escalated earlier this year. At the same time, attacks on vessels in the Red Sea have increased, creating additional challenges for global shipping.
An Indian-flagged cargo vessel reportedly sank near Yemen after being struck by a projectile earlier this week. Indian authorities confirmed that all 14 crew members were rescued safely.
Markets Await a Final Agreement
Financial markets are now closely watching whether diplomatic efforts can produce a lasting agreement.
Although oil prices have fallen on expectations of improved shipping, analysts believe volatility could return if negotiations fail. A successful agreement would help stabilise global energy supplies, while renewed tensions could once again disrupt trade and push crude prices higher.
