Global crude prices fell to three-week lows Tuesday after senior American officials indicated that talks with Iran over reopening the strategically critical Strait of Hormuz waterway have advanced significantly.

Brent crude oil dropped nearly 5% to below $80 per barrel on Tuesday following announcements from US State Department and Treasury officials that negotiations with Iran regarding the Strait of Hormuz have progressed. West Texas Intermediate prices similarly declined over 5% to $76 a barrel, with both benchmarks reaching their lowest points since mid-July. The potential reopening of this crucial shipping lane has raised investor hopes that global oil supply disruptions may be resolved.

US Secretary of State Marco Rubio stated that discussions between American and Omani officials have made headway on allowing increased maritime traffic through the waterway. Treasury Secretary Scott Bessent suggested that a deal could be finalized as early as this week, telling media outlets that a potential agreement might materialize by Tuesday or Wednesday. When asked about potential charges for passage, Bessent characterized a successful outcome as ensuring "freedom of movement" through the strait.

The Strait of Hormuz has emerged as a focal point in US-Iran tensions, particularly since late February when the conflict intensified. Prior to this period, the waterway facilitated approximately one-fifth of global daily oil and liquefied natural gas shipments. However, officials have not disclosed specific details regarding what a final agreement might entail. Previous failed negotiation attempts in recent months have contributed to volatility in oil markets, ultimately resulting in higher fuel costs for consumers at petrol pumps globally.
