Weekly Briefing — 2026-10-12 to 2026-10-18

Iran's Islamic Revolutionary Guard Corps struck at least three tankers in the Strait of Hormuz within 48 hours ending October 12, warning that vessels cooperating with the US military or using unauthorized passages would face decisive response, according to IRGC statements reported by IranWire. A supertanker carrying crude struck naval mines and caught fire on October 11 after traveling with navigation systems switched off through an unauthorized passage, the IRGC said, while UK Maritime Trade Operations recorded six separate attacks on vessels in the strait on October 11 alone. Commercial traffic through Hormuz averaged 8.6 ships per day during the seven days ending October 13, roughly 10 percent of the pre-crisis baseline of 84.8 daily transits, according to Hormuz.now tracking data.

Saudi Arabia announced plans to expand oil pipeline capacity to destinations outside the Persian Gulf to 10 million barrels per day within two to three years, Energy Minister Prince Abdulaziz bin Salman said October 12. The kingdom could add up to 1.2 million barrels per day within seven to eight weeks by temporarily converting a gas pipeline for crude shipments.

Global oil inventories fell by an average of 1.9 million barrels per day in the third quarter of 2026 and will fall an additional 0.7 million barrels per day on average in the fourth quarter, the US Energy Information Administration estimated October 6. WTI crude settled at $93.74 per barrel on October 12 and Brent at $106.65.

UAE Presidential Adviser Anwar Gargash called October 12 for renewed Gulf cooperation on security and defense, warning that attacks on Saudi Arabia undermine the security of the UAE and every other Gulf state. In a post on X, Gargash said the attacks stemmed from the aggressor's mistaken belief that Gulf countries were the weakest link in a war they had sought to avoid, and called for stronger collective security arrangements to address serious shortcomings in Gulf defense cooperation. The statement followed Houthi attacks on King Khalid International Airport in Riyadh on October 10 and 11 that Saudi authorities said caused 12 deaths and hundreds of injuries. Iran offered to mediate between Saudi Arabia and the Houthis on October 12, with Foreign Minister Abbas Araghchi warning that military solutions would further complicate regional crises, though Saudi Arabia has not publicly responded to the mediation offer.

Global container port congestion absorbed roughly 12 percent of the world's containership fleet as of early October, the highest level in four years, according to C.H. Robinson's October Edge Report. Sea-Intelligence estimates that Asian port congestion, driven by repeated typhoons and cascading delays through transshipment hubs, could take seven to 10 months to return to June 2025 levels.

Gulf states face heightened security risks from Houthi attacks while global shippers confront extended port delays absorbing 12 percent of container capacity, but causal links between regional attacks, oil prices, and logistics remain correlational in available sources, and reporting covers only October 12–13 rather than the stated October 12–18 week.
