Brent Slips to $101.72 for a Third Straight Loss as Iran Claims Four Tankers Hit Mines and API Shows 5.27M Barrel Draw

Brent crude futures traded at $101.72 per barrel in early Wednesday trading, down 1.81% from a previous close of $103.60, according to Trading Economics. The slide extends losses to a third straight session and points toward a three-week low. Oilprice.com's ticker showed NYMEX WTI front-month futures at $94.95 per barrel, down 1.19%. US markets have not opened, so both figures are live futures quotes, not settlements.

Iran Says Mines Destroyed Four Tankers South of Hormuz

Iran's Islamic Revolutionary Guard Corps said Wednesday that four oil tankers struck naval mines in a zone south of the Strait of Hormuz that Tehran has barred to shipping, per Oilprice.com. The IRGC said the vessels were still burning and that two other ships had been seized. The report did not name the vessels or their flags. We could not confirm the claim independently.

Diplomacy is running alongside the military headlines. Trump told the Financial Times the United States has no immediate plans to strike Iran, though limited defensive strikes occurred earlier this week, per Trading Economics. Qatar is mediating and both sides are reviewing new proposals. Iran's national security chief called Washington's response unsatisfactory.

Tuesday's US midterms add a second variable. Renewable energy shares rallied in Asia and Europe after Democrats won control of Congress, Oilprice.com reported. Traders are weighing whether a divided government limits the White House's room to escalate against Iran.

What the Gulf Export Shortfall Is Worth

Vortexa data cited by Reuters shows Middle East seaborne oil exports fell to 17.1 million barrels per day in October from 18.9 million in September. Kpler measured crude and condensate flows through Hormuz, the Red Sea and the Gulf of Oman at 16.1 million barrels per day, down from 17.09 million. The two trackers differ on scope, but both show a month-on-month decline.

Our arithmetic puts a number on it. At $101.72 per barrel, the 1.8 million barrel per day Vortexa decline equals $183 million of crude per day that did not reach buyers. Rystad Energy estimates Persian Gulf crude exports averaged nearly 12 million barrels per day in September and the first 20 days of October. Pre-war volumes were about 18 million, so the remaining gap of 6 million barrels per day is worth $610 million per day at today's Brent.

Rystad says a limited US-Iran agreement could arrive by mid-2027 and calls it unlikely that all points of contention are resolved within a year. That timeline implies a long stretch of structurally reduced Gulf supply. Rystad also flags renewed escalation after the midterms as a near-term risk.

Archive Callback: Same Headlines, Lower Price

Oil Authority covered a comparable setup when Iran talks pulled Brent to $104.10. Our late-October gas coverage cited Brent at $113. Against that mark, Brent has shed $11.28 per barrel, or 9.98%. Supply risk has not eased in that span, which shows how much of the October premium rested on negotiating headlines rather than physical flows.

API Draw Sets Up the EIA Release at 10:30 ET

The American Petroleum Institute estimated US crude stocks fell by 5.267 million barrels in the week ended October 30, after a 2.031 million barrel draw the week before. Gasoline rose 1.427 million barrels, distillate fell 270,000 barrels and Cushing gained 511,000 barrels. The Strategic Petroleum Reserve fell 400,000 barrels to 282.2 million.

Commercial crude excluding the SPR has lost more than 64 million barrels over 29 weeks, an average of 2.2 million barrels per week. This week's API draw runs 2.4 times that pace. EIA put US output at 13.992 million barrels per day for the week ended October 23, up from 13.269 million the prior week.

The EIA Weekly Petroleum Status Report posts at 10:30 a.m. Eastern today and will confirm or revise the API numbers. Baker Hughes publishes its rig count Friday. A larger-than-expected EIA draw would add support under WTI at a moment when Brent is testing three-week lows.
