If you heat with oil, drive a diesel, or buy anything shipped from Asia, the number that matters this week is how many tankers actually get out of the Persian Gulf. Kpler’s latest count shows oil cleared through the Strait of Hormuz averaging about 46% below prewar levels over seven days, with tanker crossings near 13 a day against roughly 50 before the war. At the same time, Iran’s navy told ships to keep their transponders on and coordinate with Iranian forces.
On the travel side, Lufthansa has now pulled Riyadh flights through 18 November, and Germany has issued a travel warning for Saudi Arabia.

The Barrels Are Getting Stuck
The Strait of Hormuz is the narrow waterway between Iran and Oman that carries oil and gas out of the Persian Gulf. Before the U.S.-Israeli war on Iran began on 28 February, about 125 large commercial vessels a day used it, carrying roughly a fifth of global crude and liquefied natural gas supply. Iran effectively closed the strait, and the U.S. Navy has since escorted Gulf exporters through it.
By September, Gulf oil flows excluding Iran had recovered to more than 81% of prewar levels (Al Jazeera). Fewer barrels out of the Gulf means higher diesel, heating oil, and freight costs for you, even if you never buy Gulf fuel directly.
That recovery reversed in October. Kpler, a commodity-tracking firm, reported on 14 October that confirmed oil clearance through Hormuz was 4,147,000 barrels a day on 12 October, with a seven-day average of 9,275,000, about 46% below the prewar baseline of 17,145,000. Tanker crossings fell to 3 on 12 October; the seven-day average was 13 a day against 50 before the war (Kpler).
Two caveats matter. The latest days are preliminary and have numbers have typically settled 1.5 to 2 times higher as confirmations arrive. Bypass routes are also running hot: Terminals at Fujairah and in Oman are loading about 21% above normal, and Saudi Arabia is pushing about 5.8 million barrels a day across its East-West Pipeline to the Red Sea.
Counting those routes, regional exports were about 28% below baseline. Energy journalist Javier Blas described total Middle East flows as “resilient” but “lumpier,” with busy days followed by nearly empty ones (@JavierBlas). Kpler also reports the Oman-to-China tanker rate doubled in a month to a record, which lifts the delivered cost of every barrel.
The attacks explain the drop. United Kingdom Maritime Trade Operations (UKMTO) recorded 15 attacks between 6 and 14 October, 11 of them in four days. Iran’s navy said it deployed new units east of the strait across the Sea of Oman and Arabian Sea, warned vessels not to switch off their transponders, and urged them to coordinate with Iranian forces for passage.
An Iranian official told Reuters that Tehran changed tactics about 10 days ago, with one goal being to influence the U.S. midterm elections (Al Jazeera). On 15 October Iran’s navy said a “violating” tanker with its tracking switched off caught fire in a restricted zone east of Hormuz. It named no vessel; Treat that as an Iranian claim (Xinhua).
I see the transponder demand as a permission system. A transponder, the Automatic Identification System (AIS) radio that broadcasts a ship’s identity and position, is a safety tool. Tehran is turning it into a check-in desk: Passage becomes something Iran grants.
Status now: Hormuz oil clearance is running roughly half of normal on preliminary data; tanker crossings are near a quarter of prewar; bypass routes cover part of the gap; Iran demands coordination.
What it means for you: Plan on diesel, heating oil, and imported goods staying expensive through the 3 November midterms. A good bypass week is not the strait reopening, no matter what Trump says.
Riyadh Is Now a November Problem
King Khalid International is Riyadh’s main airport and a connecting point for business travelers, pilgrims, and foreign workers. Houthi missiles and drones from Yemen have hit it repeatedly this month. A Notice to Airmen (NOTAM), the official notice airlines plan around, keeps it shut.
NOTAM A3604/26 still closes the airport until 21:00 UTC Saturday 17 October (3:00 p.m. CST), and Saudi Arabia’s General Authority of Civil Aviation (GACA) has not announced a reopening (NOTAC).
Airlines are planning far past that date. Lufthansa now suspends Frankfurt to Riyadh through 18 November (it was 16 October) and Dammam through 30 November (Lufthansa; reisetopia). Germany’s Foreign Office issued a travel warning for Saudi Arabia, explicitly against using Riyadh airport, and advises staying away from airports, military sites, and oil facilities (Auswärtiges Amt).
The U.S. Mission’s latest alert says Jeddah and Dammam are operating with delays and airports in Bahrain, Jordan, Oman, Qatar, and the United Arab Emirates remain open. It repeats a Saudi Interior Ministry warning that filming or sharing missile and impact sites carries legal liability, and says U.S. citizens have been detained for it (U.S. Embassy).
The war is still moving. On 15 October the Saudi-led coalition said it intercepted a cruise missile over the Medina region and a drone over Eastern Province. Houthi military spokesman Yahya Saree denied any operation that day (France 24) while declaring Saudi airspace and airports unsafe (@TheCradleMedia). Prior-day transcript color from Transition Protocol, “PEPE ESCOBAR: Pakistani Officers: Israel Picks Saudi Targets, MBS Won’t Leave His Bunker” (transcript, 2026-10-14), claims outside powers are steering the Saudi campaign; no primary source today confirms that, so treat it as opinion.
Status now: Riyadh closed to at least Saturday; Lufthansa out to 18 November; Germany warns against travel; filming impact sites can get you detained.
What it means for people affected: If you work in, visit, or connect through Saudi Arabia, plan for a month without reliable Riyadh flights, and keep your phone camera away from anything that just exploded.
Summary
Yesterday’s Strategic lead was the Houthi strike on Aramco’s Dhahran headquarters. Today rotates to the barrels themselves. September looked like recovery, with escorted tankers moving and Gulf flows near normal. October’s attack wave undid much of that at the strait, while Saudi Arabia leaned on its Red Sea pipeline and others on Fujairah and Oman. Iran now pairs the attacks with a demand that ships identify themselves and coordinate. On mobility, the Riyadh closure moved from a weekend notice to an airline schedule measured in months, plus formal travel warnings.
Outlook
(analysis, not certainty) Base case: Attack tempo stays high into the U.S. midterms, Hormuz counts stay volatile, and bypass routes keep regional exports from collapsing. I cannot predict how far Kpler’s preliminary numbers revise up, whether Riyadh reopens after Saturday, or whether a strike hits a Saudi export terminal. Watch Kpler and UKMTO counts, GACA notices, and airline schedules, not footage of burning ships.
What You Should Do Now
- Heating with oil: Book your fill on your normal schedule. Do not wait for a Hormuz headline to bring the price down.
- Order imported winter goods early. Record tanker rates and container losses show up in lead times and shelf prices.
- Avoid Riyadh routings through mid-November. Prefer Doha, Muscat, Amman, or a European hub, and confirm status with the airline.
- Check war and terrorism exclusions in your travel insurance before any Gulf trip.
- In Saudi Arabia: Do not photograph or post interception or impact sites. Detentions have already happened.
- If a relative crews tankers in the Gulf or Gulf of Oman: Keep the crewing agency’s emergency number and set a check-in routine.
What Moved Since Yesterday
- Aramco headquarters (yesterday’s Strategic lead): No new confirmed hit on Aramco production or export sites at the moment; the 15 October Medina intercept is disputed by the Houthis.
Status for you: Risk premium up, not lost barrels.
- Hormuz sinkings: UKMTO Warnings 172-26 and 173-26 describe two more container ships struck on 13 October with minor damage; both continued (UKMTO). A report of a second sinking this week is not yet matched to a named vessel.
Status for you: Boxed freight risk stays high.
- Riyadh NOTAM: Unchanged at 17 October, but airline plans now run to mid-November.
Status for you: Do not book on the NOTAM date.
- Lithuania and Kaliningrad: The request to extend about 100 soldiers on the border past 16 October awaits a decision (LRT).
Status for you: Allow extra time at Baltic crossings.
- Midterm clock: Washington’s publicly framed pause on new Iran strikes runs to 3 November, and an Iranian official now says Tehran’s shipping tactics aim at the same vote.
Status for you: Expect pressure to peak before the vote, not after.
