Crude oil prices declined more than 3% on Tuesday after markets largely dismissed the immediate impact of Washington's fresh economic pressure and secondary sanction threats targeting Iran.
Front-month West Texas Intermediate crude fell by 3.3% to $82.21 per barrel, while Brent futures were down 3.2% to $89.27/bbl. Both benchmarks hit their lowest since Aug. 17.
The market reaction was subdued following US Treasury Secretary Scott Bessent's announcement of an expansion of sanctions targeting Iran, market experts noted.
"Crude trades lower for a second day as the US ramps up economic pressure on Iran and its trading partners in an effort to force the resumption of energy flows through the Strait of Hormuz," Saxo Bank analysts said.
ING analysts noted that traders viewed the measures as marginal rather than market-moving, given the absence of strict compliance timelines or immediate secondary targets.
Maritime data from Kpler highlighted that while total vessel crossings through the Strait of Hormuz edged higher, laden transits dropped by 27% amid caution. Security alert was high after a Houthi militant attack on a Saudi oil tanker near Yanbu.
"With no further military escalation and some tankers slipping through after buying heavily discounted oil to compensate for the elevated transit risk, the market remains in limbo," Saxo Bank analysts added.
However, on the geopolitical front Pakistani Interior Minister Mohsin Naqvi reportedly held discussions with the US acting envoy in Islamabad straight after returning from Iran, where top-level Islamabad officials pushed for a resolution to the conflict with the US.
Meanwhile, market strategists emphasized that China, the primary buyer of Iranian energy, remains the pivotal factor to the effectiveness of the US sanctions package.
According to Rystad Energy senior vice president Jorge Leon, unless Beijing materially cuts its purchases, the direct impact on Iranian revenues will stay limited, and Washington is unlikely to risk a fragile trade truce over secondary sanctions.
China's top refiner, Sinopec, reported steep declines in domestic gasoline and diesel consumption during the first half of the year, driven by high prevailing oil prices and the accelerating adoption of electric vehicles.
On the supply side, data on Monday showed that US Strategic Petroleum Reserve stocks dropped by 3.7 million barrels to 289.7 million barrels, reaching their lowest level since November 1982.
