Oil prices rise as Red Sea, Gulf of Oman attacks heighten supply concerns; Strait of Hormuz reopening hopes dented

Oil prices have seen an upward trajectory over the past week amid conflicting signals regarding the reopening of the Strait of Hormuz, a vital route for global oil supplies.

Following deadly attacks by Iran-backed Houthi rebels, which resulted in six fatalities, oil futures rose significantly. Brent crude increased by over 2% to nearly $90 per barrel, reflecting heightened concerns over shipping safety in the Red Sea and Gulf of Oman.

U.S. forces also engaged in military action against a vessel attempting to breach a blockade of Iranian ports, further escalating tensions in the region.

Despite these developments, there are signs of diplomatic progress. Qatar's Foreign Ministry indicated that talks between Oman and Iran regarding the Strait of Hormuz are at an advanced stage, with hopes for a reopening soon. However, Iranian officials maintain that the strait will remain closed until the U.S. meets specific conditions, including lifting sanctions.

“Markets have not completely lost hope for a deal, but confidence is clearly eroding,” said Tim Waterer, chief market analyst at KCM Trade.

The Strait of Hormuz is crucial, carrying about one-fifth of global oil supplies before the conflict. Currently, maritime traffic is significantly reduced, with only 10 vessels crossing the strait on a recent Monday, compared to approximately 130 daily transits pre-war.

U.S. Energy Secretary Chris Wright noted that the average oil flow from the strait has recovered to about 9 million barrels per day, thanks to coordinated military efforts.

Key Insight
“Brent crude for October delivery stood at $89.61, up 24% since the US-Israel war on Iran began in late February. Just 10 vessels crossed the strait on Monday versus roughly 130 daily before the war, with Qatar saying talks are at an advanced stage.”
