Preliminary Kpler data reported by Reuters on Wednesday, 16 September 2026, put commodity-vessel transits through the Strait of Hormuz at four on Tuesday, 15 September, down from seven a day earlier and well short of the preceding ten-day average of 18. Two ships were exiting and two were entering. None of them was a very large crude carrier. None was an LNG carrier. MarineTraffic figures carried by Al Jazeera put Tuesday even lower, at three hulls: one LPG carrier and two cargo ships, one of them Iranian-flagged. On either count the waterway that handled about one-fifth of the world\u2019s oil and liquefied natural gas before the Iran war, and on the order of 125 large commercial vessels a day, is now a single-digit strait.<\/p>\n
That is not a modest wartime dip. It is the near-absence of the crude and LNG traffic that makes Hormuz matter. Tuesday\u2019s named exits were a very large gas carrier and a Panamax products tanker. The two entries were a short-range dirty-products tanker and a dry-bulk carrier, both laden, both on the Iranian-controlled route. A strait moving LPG, naphtha, dirty products and bulk is not moving Gulf crude to Asia. Cargoes not lifted this week are deliveries that do not arrive in six to eight weeks. Physical tightness in the barrel tends to print after the shipping data, not on the same day.<\/p>\n
Reuters, citing preliminary Kpler, named the exiting gas carrier as Salute<\/em>, carrying about 470,000 barrels of liquefied petroleum gas on the Iranian route. Open-register particulars for the Madagascar-flagged VLGC Salute<\/em> (IMO 8912546, MMSI 647553028, call sign 5RA28) match a 1992-built, 224-metre, 49,301 dwt fully refrigerated LPG tanker. Screening products have flagged that hull against watchlists; that is a compliance check for the next fixture, not a confirmation that Tuesday\u2019s transit was a sanctioned voyage. Until Kpler or a coastal-state notice publishes the MMSI in the day\u2019s product, treat the identification as tracker-derived.<\/p>\n The same feed named a Panamax products tanker Nautilus<\/em> exiting with about 510,000 barrels of naphtha on an unidentified dark route. A Liberian-flagged LR1 chemical\/oil products tanker of that name (IMO 1030052, MMSI 636024848, call sign 5LUO8) is a 2025-built, 228-metre, 74,916 dwt hull. Dark-route in this context means the tracker could not assign the exit to a published traffic-separation or Iranian-managed lane, not that the ship was necessarily AIS-off for the whole transit. Reuters noted that some ships may be sailing with transponders switched off and are therefore not counted at all. Four AIS-visible commodity transits is a floor, not a census. It is still an 80 percent drop against the ten-day average, and a collapse against the pre-war baseline.<\/p>\n Monday\u2019s count is the other useful comparison. Wednesday\u2019s Reuters product put Monday at seven transits. A separate Kpler read published on Tuesday had put Monday at four, down from ten on Sunday, with two dry-bulk exits and two ballast tankers entering. MarineTraffic\/Al Jazeera put Monday at five. The spread is what operators should expect when dark transits, Iranian-route assignments and delayed AIS fills sit on the same waterway. The direction is not in dispute. The strait is in single digits. VLCCs and LNG carriers did not print in Tuesday\u2019s visible set.<\/p>\n Transit counts understate the energy shock when the mix shifts away from crude. A VLCC lifts on the order of two million barrels. Tuesday\u2019s named energy exits were an LPG cargo of about 470,000 barrels and a naphtha cargo of about 510,000 barrels. There was no VLCC and no LNG tanker in the Kpler set. A drop from 18 daily transits to four is not a four-and-a-half-fold cut in oil moving through the strait. It is steeper than that, because the hulls that stopped sailing first are the ones that carry the crude. For practical purposes, Hormuz is not exporting Gulf crude on a day like Tuesday. Shuttle and ship-to-ship patterns in the Gulf of Oman, and residual U.S.-facilitated movements that do not always match AIS products, are a separate file. They do not restore a 125-ship peacetime lane.<\/p>\n CENTCOM and U.S. officials have continued to cite facilitation statistics \u2014 residual oil movements under naval cover, ships redirected, humanitarian passages. Those figures describe a military logistics problem. They are not a commercial traffic picture. JMIC still rates the strait SEVERE. Iran\u2019s Persian Gulf Strait Authority has published a Non-Compliance List that stood at 77 vessels as of 14 September, with warnings to P&I clubs and class. Iranian foreign minister Abbas Araghchi has tied any reopening to a U.S. return to commitments under the Islamabad memorandum. Oman postponed the Salalah briefing that was due on Monday. Owners price that stack as detention risk, not as a TSS amendment.<\/p>\n Formal closure is rarely what stops merchant traffic. War-risk underwriting does, and it works faster than a blockade notice. When the additional premium, quoted per voyage as a percentage of hull value, erases the charter, the owner declines the business without any authority having to prohibit it. Crew contracts that allow seafarers to refuse a designated war-risk area add a second stop. An owner cannot sail a vessel that cannot be manned. Tuesday\u2019s four-ship print is consistent with that arithmetic, not with a sudden shortage of ships in the region.<\/p>\n The workarounds are also constrained. Saudi Arabia\u2019s East\u2013West Petroline to Yanbu, which had been absorbing on the order of 4 to 5 million barrels a day after Hormuz tightened, was stopped after drone strikes on pumping stations. Rystad Energy put recent Yanbu loadings in a 2.6 to 4 million barrel-a-day range now at risk of disappearing from the market. Officials have said repairs could take weeks. Japan\u2019s shipowners, cited by the Asahi Shimbun on 13 September, warn that Saudi-to-Asia voyages could stretch to about 100 days round trip if Bab el-Mandeb closed as well, against about 40 days via Hormuz and 40 to 50 days via the Red Sea. That 100-day figure is a contingency, not today\u2019s routing. It is the measure of how little redundancy is left once both chokepoints are impaired.<\/p>\n Freight is already doing part of the rationing. A Kpler market note published on 16 September put MEG\u2013China VLCC freight at $24 per barrel and Gulf of Oman loadings outside the Strait at $12 per barrel. Freight now accounts for about 25 percent of the fob crude price from the MEG, against 17 percent at the start of the conflict and around 5 percent before the war. In the Gulf of Oman, freight is about 11 percent of crude value. Those are the highest shares of the conflict to date. For an Asian refiner the delivered cost is the barrel plus the voyage. It is the second term that has been repricing. Kpler\u2019s further point is that the next adjustment, if attacks continue at the recent cadence, is more likely to come through lower loadings than through another proportional rise in rates. A four-ship Tuesday with no VLCCs is that mechanism starting to print in the transit count.<\/p>\n A single-digit strait is a targeting and a SAR problem as well as a cargo problem. Fewer merchant witnesses, fewer assisting hulls, and a higher share of traffic on the Iranian-managed northern route all change the passage plan. Dark-route exits, such as the naphtha tanker in Tuesday\u2019s product, mean the AIS picture the next ship sees may not match the lane the last ship used. Company security officers should not treat an empty radar plot as a clear TSS. They should treat it as a waterway where residual traffic, unmanned surface craft, IRGC small boats and U.S. covering fire can occupy the same approaches, as Monday\u2019s Larak Saildrone exchange already showed.<\/p>\n The daily count is now the cleanest indicator of whether anything has changed. A move back toward double digits would mean owners and insurers believe passage is survivable again. Continued single digits, especially without VLCCs or LNG, means the commercial closure is holding regardless of facilitation statistics or postponed Gulf talks. Bab el-Mandeb, by contrast, printed 22 commodity transits on Tuesday against 24 on Monday \u2014 thin against peacetime, but an order of magnitude above Hormuz. That gap is why some liner schedules are being put back through Suez while crude remains stuck behind a strait that is no longer carrying VLCCs.<\/p>\n Regulas Shipping will keep lining Kpler, MarineTraffic and UKMTO products against the daily Hormuz count so operators can treat a single-digit, no-VLCC day as a routing and insurance decision, not as residual peacetime traffic.<\/p>\n","protected":false},"excerpt":{"rendered":" Preliminary Kpler data reported by Reuters on Wednesday, 16 September 2026, put commodity-vessel transits through the Strait of Hormuz at four on Tuesday, 15 September, down from seven a day earlier and well short of the preceding ten-day average of 18.
