Oil prices edged higher on Tuesday as investors assessed the potential impact of expanded U.S. sanctions against Iran and Tehran’s threat to retaliate, keeping concerns over Middle East crude supplies firmly in focus.
Brent crude futures rose 0.15% to $92.31 per barrel by 21:12 ET (01:12 GMT), while West Texas Intermediate (WTI) crude futures gained 0.3% to $85.28 a barrel.
The modest recovery followed a sharp decline on Monday, when traders locked in profits after reports indicated that shipping activity through the Strait of Hormuz had improved. Despite the increase in traffic, shipments remain far below levels recorded before the war. Oil prices are still more than 5% higher compared with last week.
Washington announced new sanctions on Monday targeting 60 entities and individuals linked to Iran while warning other countries against maintaining economic ties with Tehran. However, U.S. officials did not specify when penalties against countries dealing with Iran could begin.
Notably, the sanctions list did not include Chinese entities suspected of facilitating Iranian oil exports. China remains a major buyer of Iranian crude, and although Washington has repeatedly criticized those purchases, it has yet to directly sanction major Chinese banks over the trade.
Iran responded by signaling that it could retaliate against the expanded economic restrictions. Tehran has previously threatened further disruptions to Middle East oil flows in response to U.S. pressure.
The latest sanctions suggest Washington is increasing its reliance on economic measures against Iran rather than expanding military action. However, Iran has operated under extensive U.S. sanctions for decades, raising questions over how much additional pressure the new restrictions can generate.
For oil markets, the Strait of Hormuz remains the central supply risk. Commercial shipping through the strategic waterway has recently shown signs of recovery but remains drastically below pre-war levels.
Before the conflict, roughly 20% of global oil supplies passed through the Strait of Hormuz. Continued disruption therefore remains a major source of support for Brent and WTI prices as traders monitor U.S.-Iran tensions and regional crude flows.
