Iran Plans to Intensify Hormuz Tanker Strikes as API Reports 11.12-Million-Barrel US Crude Draw

Brent crude settled at $106.10 per barrel on Wednesday's ICE close, per OilPrice.com, as Iranian officials told Reuters they plan to intensify attacks on tankers transiting the Strait of Hormuz. WTI crude settled at $95.09 per barrel on Wednesday's CME close, a gain of $0.95 on the day. The $11.01-per-barrel Brent premium over WTI is more than twice the typical $3-to-$5 differential, reflecting risk concentrated on the seaborne crude supply chain rather than the US domestic market.

API Estimates 11.12-Million-Barrel Draw for Week Ending October 9

The American Petroleum Institute estimated US commercial crude oil inventories fell 11.12 million barrels in the week ending October 9, according to OilPrice.com. A draw of 11.12 million barrels across seven days implies demand and refinery throughput exceeded net supply inputs by 1.59 million barrels per day throughout the period. The official EIA Weekly Petroleum Status Report, which would confirm or revise the API figure, is delayed one day to October 15 due to the federal holiday on October 12.

The API draw adds physical tightening to a market already pricing in geopolitical risk. Oil Authority reported Brent at $104.28 on October 8 as Hormuz attacks hit a daily pace. Before that, Brent held at $103 on October 1 amid simultaneous pressure from China's fuel export suspension and a Russian diesel ban. The $3.10-per-barrel gain since October 1 represents a 3.0% cumulative advance driven by chokepoint risk, with each news cycle adding incrementally to a floor that has not broken below $103 in two weeks.

Brent-WTI Spread Embeds $7.01 of Geopolitical Loading

Under normal freight and logistics conditions, Brent and WTI trade within $3 to $5 of each other, with Brent commanding a slight premium for global delivery optionality. At a historical norm of $4 per barrel, the current $11.01 spread embeds $7.01 per barrel of geopolitical loading on any Brent-priced cargo. US shale producers, who price against WTI, do not capture this geopolitical premium in their wellhead revenues.

Henry Hub natural gas settled at $3.27 per MMBtu on Wednesday, per Rigzone, up 2.38% on the day. Rising energy costs across crude and gas are tracking toward what economists polled by Reuters forecast as a 0.6% monthly increase in US inflation for September, with energy the lead contributor. US consumers are absorbing simultaneous increases across gasoline, heating oil, and natural gas as the Brent premium ripples from global crude benchmarks into domestic retail pricing.

Houthi Threat Adds a Second Supply-Risk Vector

Separately, Houthi forces said they will resume attacks on Saudi airports and oil facilities in coming days, following a fire at a Saudi Aramco office in Dhahran. The Eastern Province, where Dhahran is headquartered, hosts the world's highest concentration of crude production and processing infrastructure. An attack on Eastern Province export terminals would affect Brent pricing independently of Hormuz transit disruption, creating a second simultaneous supply-risk vector that the market has not yet fully priced.

Brent's current $106.10 level sits squarely between Goldman Sachs' $90 December target and BMI's $100 baseline. The combination of Iran's stated escalation, an 11.12-million-barrel inventory draw, and a renewed Houthi threat shifts the balance of near-term risk to the upside. The official EIA inventory data due October 15 will be the next key data point for traders and analysts watching supply fundamentals.
