Three developments define this week's market:

  • Hormuz crude flows deteriorated sharply. Kpler reported a seven-day average of approximately 8.5 million barrels per day (MMbpd), compared with more than 20 MMbpd the preceding week, as attacks on commercial vessels intensified.

  • Freight costs are compressing refining margins. Shipping and insurance can now represent up to 30% of delivered crude costs for some refiners, compared with a typical 3–7%.
