Strait of Hormuz Security Assessment: Transit Drops to 4 Vessels as East-West Pipeline Halts Yanbu Loadings

Status: RESTRICTED

Shipping Assessment: Visible commercial vessel transits through the Strait of Hormuz dropped to four on September 15, 2026, compared to seven on September 14, 2026 . No Very Large Crude Carriers (VLCC) or Liquefied Natural Gas (LNG) tankers transited openly. The four recorded transits consisted of the Very Large Gas Carrier 'Salute' carrying 470,000 barrels of liquefied petroleum gas, the Panamax tanker 'Nautilus' carrying 510,000 barrels of naphtha on an unmonitored route, one short-range dirty products tanker, and one dry bulk carrier . Spot charter rates for supertankers moving crude from the Persian Gulf to China crossed $1,000,000 per day for the first time in history . Operators are increasingly using dark transits with Automatic Identification System (AIS) transponders disabled to evade interdiction.

Naval Activity: United States Central Command (CENTCOM) confirmed destroying two Iranian fast boats on September 14, 2026, near Larak Island after IRGC personnel attempted to capture a US Navy unmanned surface vessel (Farsi independent media, ahead of English reporting). Iranian state media claimed the strike hit civilian fishing boats near Bandar-e Korgan (Iranian state media, reflects regime position). The IRGC Aerospace Force reported shooting down three US MQ-1 surveillance drones over eastern and western sectors of the Strait of Hormuz on September 15, 2026 (Iranian state media, reflects regime position). On September 15, 2026, CENTCOM hosted a closed coordination conference in Germany with military chiefs from Israel, Saudi Arabia, the United Arab Emirates, Bahrain, Kuwait, Qatar, Jordan, and Egypt to establish joint maritime escort protocols .

Insurance Premiums: Underwriters have increased additional war risk premiums (AWRP) across the Persian Gulf, Gulf of Oman, and southern Red Sea. Surcharges now exceed 1.25 percent of insured hull value per seven-day voyage, up 340 percent since the start of regional hostilities. Mutual P&I clubs have issued strict warranty clauses requiring 48-hour pre-entry notifications for any transits within 50 nautical miles of Iranian territorial waters. The disabled Panama-flagged tanker 'EL GAIA', struck by missiles and drones off Oman, required emergency salvage towing while 23 crew members were evacuated into Omani ports . High war risk pricing has rendered spot crude freight financially unviable for non-state-backed fleet operators.

Price Movement: Brent crude futures traded at $108.02 per barrel at 0450 GMT on September 16, 2026, following a settlement near $108.75 on September 15 . West Texas Intermediate (WTI) futures stood at $104.73 per barrel. Physical sweet crudes gained higher premiums, with Azeri Light crude trading above $120 per barrel . Upward price momentum was temporarily slowed by American Petroleum Institute (API) data showing a 7.1-million-barrel build in US crude inventories for the week ended September 11, 2026 . Diesel crack spreads reached historic highs, driving US national retail diesel to $6.27 per gallon and European diesel futures to record levels .

Opec Response: Saudi Aramco suspended crude loadings at its Red Sea terminal of Yanbu on September 15, 2026, and notified European refiners of cargo cancellations for late September . Riyadh began offering replacement loadings to Asian refiners via ship-to-ship transfers off Sohar, Oman, to bypass both Hormuz and the Bab el-Mandeb . Abu Dhabi National Oil Company (ADNOC) expanded its trading arbitrage by purchasing 72 million barrels of discounted Iraqi crude at discounts between $24.90 and $27.00 per barrel for processing at Ruwais, freeing domestic Murban crude for export [Javanmardi77] (Farsi independent media, ahead of English reporting). Libya experienced renewed output drops after Petroleum Facilities Guards shut main transport pipeline valves across three major oil fields on September 15, 2026 .

Supply Disruption Assessment: The outage of Saudi Arabia's 1,200-kilometer East-West pipeline removes roughly 4,000,000 barrels per day of bypass capacity, equivalent to 4 percent of global crude supply . Combined with Hormuz transit reductions, over 14,000,000 barrels per day of crude and condensate flows are delayed or rerouted. Developed economies have drawn down more than 310 million barrels of strategic and commercial stocks over recent months to offset physical deficits (originally reported in Russian). Downstream refiners across the Mediterranean and Northwest Europe face acute feedstock shortages, driving middle distillate inventories below critical thirty-day reserve thresholds.

Btc Pipeline: The Baku-Tbilisi-Ceyhan (BTC) pipeline, South Caucasus Pipeline (SCP), and Sangachal Terminal are operating securely at maximum throughput under protection by the Special State Protection Service of Azerbaijan . At the 5th Azerbaijan-Turkey Energy Forum, energy ministers signed agreements to maximize BTC daily throughput and advance an cross-border 'Electric TANAP' transmission corridor . Kazakhstan is seeking to increase trans-Caspian crude shipments into the BTC network to bypass Black Sea bottlenecks, but physical transit remains constrained to 2.2 million tons per year due to tanker availability at the Port of Aktau . Baku and Astana are also exploring utilizing the Baku-Supsa pipeline for up to 5 million additional tons annually.

Other Pipelines: Saudi Arabia's 1,200-kilometer East-West crude pipeline remains fully shut down following drone strikes launched on September 12, 2026, against three pumping stations . US Energy Secretary Chris Wright stated repairs could restore flows within days, though industry operators estimate full restoration may take weeks . In Libya, Petroleum Facilities Guards forcibly closed the main pipeline valve on September 15, 2026, shutting in production across two major fields and one central pumping station . In the South Caucasus, Gazprom Armenia suspended Russian natural gas deliveries from September 15 to September 25, 2026, citing unscheduled maintenance, prompting Armenia to draw on Iranian gas swaps and domestic storage .

Pakistan: Pakistan faces severe balance-of-payments strain from import fuel inflation. The benchmark KSE-100 index shed 857.46 points on September 16, 2026, falling to 168,534.86 due to heavy selling across oil marketing companies, banks, and automotive assemblers . Prime Minister Shehbaz Sharif rolled out a targeted subsidy of 100 rupees per liter for motorcycles, rickshaws, and small cars . The Sindh Provincial Assembly passed a unanimous resolution on September 15, 2026, demanding the federal government end daily fuel price revisions and eliminate the 100-rupee petroleum levy . At the Gastech 2026 conference in Bangkok, Universal Gas Distribution Company (UGDC) pitched joint ventures to US and international investors to build private LNG import infrastructure . Gwadar Port and Muscat Port are finalizing a sister-port agreement to capture diverted regional shipping traffic .

Azerbaijan: High energy prices provide massive fiscal windfalls to Azerbaijan, with Azeri Light crude exceeding $120 per barrel and expanding State Oil Fund (SOFAZ) foreign exchange reserves . SOCAR maintained full operational readiness across offshore Azeri-Chirag-Gunashli (ACG) and Shah Deniz fields. Fitch Ratings affirmed SOCAR's credit profile on September 15, 2026, citing favorable export cash flows . Azerbaijan's State Border Service maintained high security along the southern border with Iran, intercepting drug trafficking and smuggling attempts across Goytepe and Julfa checkpoints . Following Russian gas suspensions to Yerevan, Azerbaijani officials indicated willingness to supply gas to Armenia upon completion of the Washington-brokered peace accord .

Georgia: Georgia's transit corridors, including the South Caucasus gas pipeline, BTC pipeline segments, and the Baku-Tbilisi-Kars (BTK) railway, continue operating without disruption under elevated physical security protocols . High regional refined product prices increased domestic transportation costs across Georgian commercial hubs. State utility Energo-Pro scheduled broad electrical maintenance outages across Batumi and the Adjara region on September 16, 2026 . Georgian maritime authorities issued precautionary safety notices for merchant vessels operating in the eastern Black Sea after drone strikes damaged commercial cargo vessels earlier in the week .

• Secure alternative middle distillate supply agreements immediately; European and South Asian buyers should lock in non-Gulf diesel and gasoil contracts before fourth-quarter inventory draws accelerate.
• Transition Arabian Gulf tanker charters to ship-to-ship transfer points outside the Strait of Hormuz, utilizing Omani ports such as Sohar, Duqm, or Salalah to minimize war risk insurance surcharges.
• Review force majeure clauses in European crude purchase contracts following Saudi Aramco delivery cancellations from the Yanbu terminal.
• Hedge diesel and jet fuel price exposure using forward swap contracts to cushion against refining margin volatility and crack spread widening.
• Establish redundant overland freight options across the South Caucasus corridor, capitalizing on operational Baku-Tbilisi-Kars rail capacity and Middle Corridor routes.
• Verify secondary power generation and industrial fuel stockpiles across South Asian production facilities to mitigate scheduled municipal power cuts and fuel supply rationing.

• Extended Yanbu Export Outage:
• Total Hormuz Day-Transit Boycott by Western Tanker Fleets:
• Downstream Refined Product Rationing in South Asia:
