Iran’s Tanker Attacks Keep Pump Prices High Even as Gulf Oil Exports Rebound

Crude Oil Crude Oil News Diesel Downstream ENB Publisher Picks Energy Crisis Exports Gasoline Geopolitical Geopolitical Industry Insights International News Tanker Top News U.S. Energy News US Energy News

Crude dipped below $98 Tuesday on recovering Middle East exports and a G7 stockpile release, then climbed back to $100. Gasoline is still $4.37 and diesel $6.32. Nearly 20 ship attacks in a month, “scarily thin” inventories and an SPR at a 44-year low say the relief is fragile.

On paper, Tuesday looked like relief. Gulf oil exports outside Iran recovered to more than 81% of pre-war levels in September, according to Kpler data cited by Al Jazeera. Saudi Arabia’s energy minister said flows on the East-West Pipeline to the Red Sea had reached 5.8 million barrels (Reuters). The G7 has promised 100 million barrels of crude and diesel from emergency stocks. Brent was down $2.77 at $97.55 in morning trading (Reuters via Euronext) and touched $97.06 at its low (WSJ).

It didn’t last. Brent settled up 26 cents at $100.58, and WTI rose a penny to $89.44. The same day, a projectile hit the tanker On Peace in the Strait of Hormuz and injured 12 crew members, 11 of them Indian (The Hindu). Iran has stepped up its tanker attacks: nearly 20 commercial ships came under fire around Hormuz in the past month (CNBC). At the pump, AAA’s national averages were $4.369 for regular and $6.315 for diesel. That is 39% and 72% above a year ago (AAA).

More oil is getting out, at a price

The rebound is real, but it is expensive. Kpler data published Monday showed Hormuz crude averaging 10.3 million barrels a day in the week ended Saturday. That is about 23% below the pre-war baseline of 13.5 million b/d. Windward put flows at 9 to 10 million b/d against a 14.5 million b/d baseline (CNBC) (Chart 2). Kpler estimates about 40% of exports now bypass the strait. Much of the crude that does cross is shuttled through and moved onto bigger tankers offshore in the Gulf of Oman (Al Jazeera).

That system runs on U.S. naval protection along Oman’s coast, and the risk shows up in freight rates. Moving one tanker of crude from the Gulf to China now costs about $1 million a day (CNBC). The International Maritime Organization counts at least nine sailors dead, 18 injured and three missing since July. “Nobody in Washington thinks this is sustainable financially,” said Bob McNally, president of Rapidan Energy. He added: “If the market believed that this was sustainable, I think you would be seeing much lower prices.”

The attacks are not slowing. Kuwait’s VLCC Kazimah III caught fire after being struck on Oct. 1, and the Aframax Lipsi was hit on Oct. 4 (Al Jazeera). On Monday, Iran’s Revolutionary Guard ordered a tanker to turn around or face attack, and it complied (CNBC). The Maritime Executive counted On Peace as the 12th likely Iranian attack since last Wednesday (Maritime Executive). “The oil market is not becoming more secure,” said Richard Meade of Lloyd’s List. “It is becoming more efficient at operating under sustained insecurity” (CNBC).

Why the pump hasn’t followed crude down

Crude has eased from its September highs. EIA’s Brent spot price fell from $130.80 on Sept. 15 to $113.96 on Sept. 29, and WTI spot fell from $107.02 to $96.16. Front-month Brent futures are now near $100 (Chart 1). Retail fuel has come down more slowly. Regular is 8.7 cents below a week ago, and diesel is 12.4 cents lower. Diesel is still within 22 cents of AAA’s record $6.528, set Sept. 22 (AAA) (Chart 3). Three things hold them up:

  • The risk premium sits in delivered barrels. Benchmarks stay high because “it’s still costly to deliver and insure and land crude in consuming regions where benchmark prices are set,” McNally said (CNBC). EIA’s physical Brent spot price was still $113.96 on Sept. 29, the latest available.
  • Diesel is the tight product. In an ENB calculation, crude (WTI ÷ 42) accounts for about $2.13 of today’s $6.32 diesel. Everything else is roughly $4.19 a gallon, nearly double the $2.19 of a year ago (Chart 4). That residual covers refining, freight, taxes and retail margin. The wars in Iran and Ukraine have curtailed product exports and damaged refineries (Reuters).
  • Thin cushions. Aramco CEO Amin Nasser told the Energy Intelligence Forum on Monday that the world’s “supply resilience cushion” is “scarily thin” and that stock releases “cannot fix” the problem (Politico). He said nearly 3 billion barrels of supply have been lost since February, and rebuilding stocks could take up to two years after Hormuz reopens (Al Jazeera).

Chart 3. U.S. retail regular gasoline and diesel, weekly (EIA), with AAA daily national averages. Sources: U.S. EIA; AAA (as of 10/6/2026).

Who pays

Diesel moves freight, harvests, and heavy equipment, so its 72% annual jump hits truckers and farmers hardest. Then it passes into the price of nearly everything else. AAA shows California diesel at $8.364 and Washington at $7.330. Texas is lowest at $5.736 (AAA state averages). The American Farm Bureau Federation wrote the White House on Oct. 1 that “farmers and ranchers cannot postpone harvest or simply stop using diesel when prices rise” (AFBF). President Trump’s Oct. 5 executive order defers the federal highway diesel tax and allows dyed diesel on highways through Dec. 31. That is tax relief, not new supply. Drivers pay about $1.24 a gallon more for regular than a year ago, four weeks before the midterms.

The case that relief sticks

  • Volumes are back. Kpler’s seven-day average of Middle East crude exports hit 18.3 million b/d on Sept. 30. That compares with about 18 million b/d in the year before the war, and exports topped pre-war levels on 14 days in September (Al Jazeera). Vitol’s CEO said about 12 million b/d of crude and 2 million b/d of products left the region in the last 7 to 10 days (Reuters).
  • Stocks are coming. The G7 agreed Oct. 2 to a “co-ordinated release through the IEA of 100 million barrels to begin immediately over four months, including a frontloaded substantial diesel release within the first 20 days” (BBC). The IEA board is expected to set the details at its Oct. 14–15 meeting (Reuters).
  • No export ban. Trump dropped his threatened U.S. diesel export ban: “We’re not going to be doing the export ban” (Fortune). The G7 also pledged no energy export restrictions among members. Analysts had warned that a U.S. ban could backfire by cutting refinery runs and gasoline supply (Fortune).

The case that it’s fragile

  • The bypass is under fire. A Saudi energy-sector source told AFP that a Sunday attack had again halted pumping on the East-West Pipeline. On Monday the Houthis claimed strikes on Riyadh’s airport and an Aramco refinery (AFP). That conflicts with the minister’s Tuesday figure of 5.8 million barrels, and neither side has reconciled the two. The line was already shut on Sept. 11 after drones from Iraq hit it. Reuters later found three pumping stations damaged (Guardian; Reuters).
  • The G7 number is fuzzy. The G7 gave no split between crude and diesel, no country shares, and no word on how much overlaps with March’s record 400-million-barrel release (Reuters). Two diplomats noted that 100 million barrels is about one day of world oil use (Foreign Policy Journal).
  • America’s cushion is spent. The Strategic Petroleum Reserve fell to 283 million barrels, its lowest since October 1982 (Reuters via BOE Report). EIA data show 131.7 million barrels drawn since the war began (Chart 5) (EIA). The National Hurricane Center also gave a 100% chance that a cyclone forms in the Gulf of Mexico within seven days (Reuters).

The bottom line

The barrels are moving, but under fire, under escort, and at about $1 million a day in freight per tanker. As long as that holds, pump prices should drift lower, slowly. Diesel will lag because of its product-specific squeeze. A single successful strike on the East-West line or a major tanker could erase the gains quickly, with the SPR near a 44-year low and global stocks thin. As PVM’s Tamas Varga told Al Jazeera, only “a sustainable and credible peace deal” and a permanent reopening of Hormuz would restore the pre-war status quo (Al Jazeera). Watch three things: the IEA board on Oct. 14–15, the G7 diesel barrels due within 20 days of Oct. 2, and Wednesday’s EIA inventory report.

Dates are as reported by each source. “Past month” attack totals (nearly 20 ships, per JMIC via CNBC) include incidents not listed individually by any source ENB reviewed.

Appendix D. Data gaps, conflicting claims and numbers that don’t exist

East-West Pipeline: conflicting claims. On Oct. 6, Saudi Energy Minister Prince Abdulaziz bin Salman said East-West flows had “reached 5.8 million barrels as of Tuesday morning” (Reuters). AFP reported the same day that a Saudi energy-sector source said a Sunday (Oct. 4) attack “had again halted pumping” (AFP). Both can be true if pumping stopped and then restarted, but no source ENB found confirms a restart or gives a timeline. Note also the unit: Reuters wrote “5.8 million barrels,” not “barrels per day.” The briefing’s “5.8 mb/d” reading is plausible but not what the published text says. ENB reports it as written.

Brent “falling” vs. Brent settling higher. The early Reuters version (Brent −2.8% to $97.55) was overtaken by the close. Brent settled up 26 cents at $100.58 and WTI up a penny at $89.44 (Reuters; WSJ). The WSJ changed its headline from “Oil Prices Fall …” (still in the URL) to “Oil Prices Recover …”. ENB’s “crude dipped” framing refers to the intraday low and to the decline since mid-September.

Hormuz flow baselines differ. Kpler uses a 13.5 mb/d pre-war baseline; Windward uses 14.5 mb/d. The 81% figure covers Gulf exports outside Iran by all routes, including the East-West Pipeline and Iraqi and UAE alternatives, not only Hormuz transits. These numbers are not interchangeable.

Nasser’s loss figure. Al Jazeera reports “nearly three billion barrels of oil supply had been lost”; Politico reports “around 30% of the world’s oil stocks” lost. ENB found no transcript that reconciles the two.

G7 barrels. No breakdown of crude vs. diesel, country shares, or overlap with the March 400M-barrel release has been published (Reuters; To Brief). The U.S. share is unknown. ENB therefore did not chart the G7 release by product.

Risk premium. No source quantifies a dollar-per-barrel “Hormuz risk premium.” ENB does not estimate one. Chart 4’s “everything else” is a residual (retail minus crude/42), not a measured refining margin or risk premium. It also mixes EIA spot (year-ago) with futures (today) crude prices.

Spot vs. futures. EIA’s Brent spot series (physical, through Sept. 29) ran well above front-month futures in late September. ENB has no same-day futures series to measure the gap, so it does not state a spread.

Attack counts. “Nearly 20” in the past month (JMIC via CNBC), “at least seven” in the past week (Marisks via Al Jazeera), and “12th likely Iranian attack since last Wednesday” (Maritime Executive) use different windows and definitions. The date of the On Peace strike is also unsettled: India and Oman say Tuesday, and Maritime Executive says it may be Monday’s UKMTO report.

Houthi claims. The Houthi claim of strikes on Riyadh airport and an Aramco refinery comes from a Houthi spokesman via AFP. ENB found no Saudi or Aramco confirmation of refinery damage.

Pass-through timing. No source gives an expected date or size for pump-price relief from the G7 release. ENB’s “drift lower, slowly” is analysis, not a forecast from a source.

WSJ body text. Paywalled; not used beyond title, byline and summary line. No WSJ bylines are attributed to the ENB article.
