1. Three-Layer Pricing Breakdown
1. OSP official price (SOMO, announced Oct 8, for Nov loading): Basrah Medium set at a discount to the Oman/Dubai average; Basrah Heavy widened its discount, reflecting Iraq's adjusted pricing strategy amid regional coordination. The cut follows Saudi's November Arab Light to Asia at -5.00 (deepest since Jun 2020), a coordinated Middle East market-share defence.
2. Spot dark discount : Recent-loading cargoes show FOB dark discounts deeper than recent historical levels, reflecting Iraq's enhanced incentive amid geopolitical tensions and fleet constraints. Loading premium +30% mechanism: The non-Hormuz loadport premium persists (1–10 day laycan ≥0.20, 11–30 day ≥3.00 USD/bbl), plus offshore STS transfer surcharge, further lifting delivered cost.
2. For Medium: OSP discount to Oman/Dubai plus spot rebate yields a significantly negative FOB net; Heavy remains more attractive on a relative basis. Adding current VLCC freight and war risk — with underwriters applying elevated hull surcharges and shippers absorbing higher costs — delivered ICE Brent parity sits at a premium, maintaining this tier as the most economical Middle East sour option despite rising absolute delivered cost. Hormuz: On Oct 21, reported incidents occurred near shipping lanes in the Gulf region; transit volumes remain substantially below pre-conflict levels. IEA/gCaptain (Oct 21) report Gulf shipping costs have risen markedly; London underwriters price additional war-risk premiums at elevated levels, with crew refusals and shippers absorbing higher freight that pressures Asian refiner margins. Shandong run-rate dropped to ~55% end-Sept with margins turning negative — delivered premiums above +20/bbl meet limited uptake; control delivered cost and war-risk exposure.
