Hormuz Daily — 2026-08-28

BLUF: Two tanker strikes this week failed to move crude off ~$82 — the market has decided the Iran–Oman transit deal happens and is pricing attacks as friction, not escalation. Fee percentage (3% vs 5–7% of cargo value) is now the whole ballgame; US rejection of any Iran-payable fee is the unresolved fault line.

Incidents

  • Aug 24: Projectile struck a Liberian-flagged tanker ~9nm NE of Ash Shishan, Oman; engine room hit, vessel disabled, crew safe per UKMTO.
  • Aug 26: Second commercial tanker struck in the Strait of Hormuz; fire extinguished. Second strike in 72 hours.
  • Running toll since war began: ~65 attacks on commercial vessels, 17 mariners killed.
  • No attribution on this week’s strikes — spoiler-faction vs. deniable IRGC pressure ahead of deal signing is the open question.

Deal Watch — Iran–Oman Transit Framework

  • Aug 26: Iran and Oman announced an interim framework to resume transits and share strait revenue. IRGC claims agreement on water shares and revenue split; the joint FM statement stopped short of a final deal and omitted fees entirely.
  • Fee gap: Iran demands 5–7% of cargo value; Oman proposes 3%; the US categorically opposes any fee payable to Iran. Trump publicly called a Hormuz toll “a beautiful thing” — daylight between POTUS framing and official US position is a negotiation tell.
  • Structure: inbound traffic via northern corridor (Iran-managed), outbound via southern corridor (Oman-managed); later consolidation to a central corridor with service-based (not ad valorem) fees.

Flows & Traffic

  • US-brokered covert southern corridor along the Omani coast is moving 15–20 tankers/night, ~10M bbl/d — roughly half pre-war volume.
  • Spike of ~40 tanker transits Friday night (Aug 21–22), but traffic settled back down; pre-war baseline was 130+ crossings/day.
  • ~70 ships remain trapped in the Persian Gulf (USNI, Aug 7).
  • ~6M bbl/d of refining capacity offline; Mideast product exports still shut in (S&P est.).

Markets

  • Brent Crude near **100 during the shipping freeze and ~$93 earlier in August. Deal optimism is fully dominating attack risk.
  • Asymmetry note: a signed deal is largely priced in; a collapse over the fee % is not. Skew favors upside crude risk.
  • US naval blockade (Apr 13 – May 29) remains ended; conflict has shifted to economic warfare.
  • US presence: ~13 warships incl. carrier strike groups, F-35s, destroyers — deterrence signaling, escorts implied for corridor traffic.

Watch Items

  • Attribution on Aug 24/26 strikes — deniable pressure or deal spoilers?
  • Fee % landing zone (3 vs 5–7) and whether US blesses any Iran-payable structure
  • War-risk insurance premium response to this week’s strikes
  • Whether nightly corridor volume holds above 10M bbl/d
  • Fate of the ~70 trapped vessels under the interim framework
