Oil prices extended their decline for a third consecutive day on Wednesday, with Brent crude falling 2.6% to $86.2 a barrel and U.S. West Texas Intermediate crude slipping 2.5% to $80.3. This downturn reflects growing optimism that negotiations between Iran and Oman could alleviate one of the biggest supply risks in global energy markets, specifically the reopening of the Strait of Hormuz. The previous session saw both benchmarks drop more than 3%, contributing to the downward pressure on crude prices as traders assessed the possibility of improved oil flows through the key waterway.

Iran announced it had resumed talks with neighboring Oman on managing traffic through the Strait of Hormuz, with discussions including a temporary joint shipping route and clearing mines from the waterway. This diplomatic progress suggests that a meaningful reopening of the Strait could allow more oil tankers to transit the route, thereby reducing the geopolitical risk premium that has kept crude prices elevated. Before the conflict began in February, the Strait of Hormuz handled approximately one-fifth of global oil and liquefied natural gas shipments, and its disruption has created significant uncertainty regarding the availability and cost of crude and refined fuels.

Adding to the downward pressure, the American Petroleum Institute reported that U.S. crude inventories increased by about 4.2 million barrels in the week ended August 21, significantly exceeding analysts' expectations of a 600,000-barrel rise. This larger-than-expected build could further depress crude prices by reinforcing concerns about demand and available supplies. Analysts noted that while the latest diplomatic developments have encouraged selling, volatility is expected to remain high due to the uncertainty surrounding the full reopening of Hormuz and ongoing U.S. sanctions, which remain a significant factor for the oil market.
