Bessent Plans Iran Oil Buyer Sanctions as WTI Falls to $85 Per Barrel

WTI crude oil fell 2.34% to $85.02 per barrel on Monday, per OilPrice.com price data updated midday on August 24. Brent dropped 2.17% to $92.34 per barrel on the ICE in the same session. Both benchmarks had rallied more than 5% the prior week on escalating U.S.-Iran tensions before Monday's profit-taking.

Treasury Secretary Scott Bessent is scheduled to hold a press conference Monday afternoon to unveil new economic measures targeting Iran's oil revenue. Bessent has characterized the forthcoming campaign as an "economic D-Day." The measures target three categories: buyers of Iranian petroleum, entities facilitating financial transactions for Iranian crude, and companies enabling physical fuel transfers.

This follows a volatile stretch in global oil markets. Oil Authority previously reported that Brent settled at $83.55 and WTI at $78.18 after a 7% weekly drop when progress on the Iran-Oman diplomatic corridor deflated the Hormuz risk premium. Prices recovered more than 5% the following week as U.S.-Iran military tensions re-escalated, before Monday's pullback.

CENTCOM Blockade Metrics

U.S. Central Command has redirected 70 commercial vessels and disabled three others since the naval blockade began, according to CENTCOM statements reported by OilPrice.com. Fewer than 20 vessels were transiting the Strait of Hormuz on Monday. The Strait handles roughly 20% of globally traded oil under normal conditions, per EIA estimates. Iranian officials warned that participation in U.S. economic measures constitutes "an act of war."

The EIA's August 2026 Short-Term Energy Outlook, released August 11, models "continued severe constraints on Strait of Hormuz transits" as its central scenario. The agency estimates supply disruptions of approximately 0.6 million barrels per day continuing through the end of 2027. U.S. commercial crude inventories are expected to remain below the five-year average low through the end of 2026, the STEO states.

The Buyer-Side Sanctions Shift

Prior U.S. sanctions campaigns against Iran targeted Iranian banks, shipping firms, and oil exporters directly. The Bessent approach targets the buyers instead, forcing Chinese refiners and other importers to choose between Iranian barrels and access to the U.S. financial system. Iranian crude offers to China's independent teapot refiners had already declined in the days before Monday's announcement, according to market intelligence reported by OilPrice.com.

If the campaign suppresses an additional 0.1 million barrels per day of Iranian exports beyond what the EIA already models, Tehran loses roughly $3.4 billion of annualized crude oil revenue at current Brent prices. That calculation holds for each additional 0.1 mb/d increment of supply removed from global markets. The EIA's 0.6 mb/d baseline Hormuz disruption estimate sets the floor; Bessent's sanctions add buyer-side pressure on top of that existing supply constraint.

EIA Price Forecast Versus Monday's Intraday Prices

The EIA's August 2026 STEO projects Brent crude at approximately $85 per barrel for the third quarter of 2026. Monday's intraday Brent price of $92.34 per barrel sits roughly $7 above that central forecast. The gap represents the geopolitical risk premium markets are carrying over the EIA's baseline scenario, which already incorporates 0.6 mb/d of Hormuz disruption.

The STEO projects a price reversal in 2027, with Brent declining to approximately $69 per barrel as disrupted Middle East production returns to near pre-conflict levels by early 2027. That forecast assumes the Hormuz situation begins normalizing in late 2026. A durable buyer-side sanctions campaign that restricts Iranian exports beyond the EIA baseline keeps prices elevated relative to that 2027 central case.

Goldman Sachs warned this week that European natural gas markets face a winter supply challenge. Gas prices need to rise substantially by December to incentivize storage filling, contingent on Hormuz constraints persisting. European LNG demand is already elevated, with spot cargoes filling the role of piped supply disrupted by Middle East tensions.
