Energy shares fall as Iran deal lowers Hormuz disruption risk

By Arunima Kumar

Market reaction to Iran-U.S. agreement and oil price movements

June 15 (Reuters) - U.S. energy shares fell in premarket trading on Monday as crude prices tumbled after Washington and Tehran reached an initial deal that could end the months-long conflict and reopen the vital Strait of Hormuz.

Details of the Iran-U.S. agreement

The U.S. and Iran will sign a memorandum of understanding in Switzerland on Friday, Pakistan's prime minister said, after his country helped mediate talks between the two sides.

U.S. President Donald Trump said on Sunday the Strait of Hormuz, which carries roughly a fifth of global oil consumption, would be open "toll free" and that a U.S. naval blockade of Iranian ports would end.

Analyst perspectives on oil market recovery

"Markets will price in a large optimism discount that 'normality' is returning, although we would caution that flows are not likely to resume to anywhere near pre-war levels for months, and investors should follow how quickly Gulf producers are able to resume oil production and exports following damage from the war and whether more ships will enter the region," said Ashley Kelty, analyst Panmure Liberum.

Impact on crude prices and key energy stocks

Brent crude futures fell 4.8% to $83.10 per barrel by 1047 GMT, while U.S. West Texas Intermediate crude was down 5.2% at $80.46 per barrel. [O/R]

Performance of major U.S. energy companies

Shares of Exxon Mobil and Chevron fell 2.6% and 2.5%, respectively.

Diamondback Energy, Devon Energy, ConocoPhillips and Occidental Petroleum were down between 2.6% and 3.2%.

Refiners Valero Energy, Marathon Petroleum and Phillips 66 also declined between 2.5% and 3%.

European energy stocks reaction

In Europe, shares of BP fell 3.4%, while Shell dropped 4.3%.

Outlook for energy sector and oil shipments

Energy stocks had rallied since the conflict broke as concerns mounted that it could disrupt shipments through the Strait of Hormuz. Analysts cautioned that physical oil markets could take longer to recover than financial markets.

Challenges facing oil market normalization

Logistical and insurance concerns

"Even if ships now have safe passage, tankers are in the wrong place, oil production/refining facilities need to get up to full capacity, and questions over the cost and availability of insurance for ships traversing the Strait will remain," said Capital Economics group chief analyst Neil Shearing.

Key Takeaways

  • A preliminary peace agreement, to be formally signed Friday in Switzerland, is expected to end hostilities and reopen the Strait of Hormuz, easing a major chokepoint that normally handles ~20% of global oil and LNG flows. (axios.com)
  • Crude prices plunged—Brent down ~4–5%, WTI similarly—pulling U.S. energy shares lower, including Exxon Mobil, Chevron, refineries and European majors, as markets priced in ‘return to normal’ optimism. (internazionale.it)
  • Analysts warn that physical markets may lag financial sentiment—challenges like damaged infrastructure, insurance costs, and repositioning of tankers mean full oil flow recovery may take months. (investing.com)
