Trade & maritime brief — Saturday, 18 July 2026

• Hormuz throughput: IMF PortWatch (as of 2026-07-12) shows only 10 Hormuz transits vs a 16.4 7-day average, with just 1 tanker vs 6.3 average and cargo capacity of ~170kt vs a ~727kt average — a ~77% collapse. Treat Gulf loadings as severely impaired; price Gulf-origin crude and product with wide delay/war-risk premia.
• Bab el-Mandeb next: Reuters-sourced reporting says Iran has asked the Houthis to prepare to close Bab el-Mandeb if the US hits Iranian power infrastructure, and a tanker (Asana) was seized off Yemen. The strait is still flowing normally today (41 transits vs 32.3 avg), so hedge Red Sea exposure now while it is cheap — the signal precedes the disruption.
• Cape reroute is real: Cape of Good Hope cargo capacity is running ~18% above its 7-day average (6.81mt vs 5.78mt) — the reroute is already in motion. Expect tonne-mile demand and Asia-Europe transit times to rise; note Korean/Japanese refiners say they will keep the Red Sea route for Saudi crude, so the diversion is not uniform.
• Oil and diesel: WTI $79.20 / Brent $81.62 (EIA/FRED, 13 Jul), up ~$7 on the prior print. Russia's diesel export ban (products already -14% m/m in June) stacks a distillate shock on top of the Gulf crisis — diesel cracks are the tightest leg; US Gulf exports (3.72m b/d, +459k w/w per EIA) are the swing supply.
• Container market turning: Drewry WCI fell for the first time since April (Shanghai-Rotterdam -1% to $4,873/40ft) with capacity rising and demand cooling; UNCTAD warns high freight rates are straining vulnerable economies. Do not chase box-rate strength into Q4 — geopolitics, not demand, is the only bull case left.
• Tariff/regulatory watch: The US administration is racing to rebuild tariffs struck down by the Supreme Court while China's own sanctions arsenal expands, and the EU proposed extending ETS to ships over 400 GT — compliance and duty exposure on both transpacific and EU trades needs re-pricing.

Strikes widen to infrastructure as Hormuz flows run at a quarter of trend — and Tehran points the Houthis at Bab el-Mandeb

The US struck bridges and an airport in Iran on Friday; Iran answered by hitting a power and desalination plant in Kuwait — the first time both sides have deliberately expanded targeting to civilian infrastructure in third countries. gCaptain's read is blunt: despite daily strikes, Iran's speedboats, missiles, drones and mines can still deny the Strait of Hormuz, and INTERTANKO now warns the threat to commercial shipping extends across the whole Gulf region. Traffic data backs the fear: IMF PortWatch (satellite AIS, as of 12 July) counts just 10 Hormuz transits against a 16.4 seven-day average, with tanker transits down to 1 from an average of 6.3 and cargo capacity through the strait at ~170,000t versus a ~727,000t average — roughly a 77% collapse in volume terms. Our own terrestrial feed has no Gulf coverage this window, so PortWatch is the authoritative read.

The second front is forming at Bab el-Mandeb. Reuters sources say Iran's leadership has discussed and conveyed to the Houthis a request to prepare to close the strait if the US attacks Iranian power infrastructure — which it now arguably has. On the same day, suspected pirates (or worse) seized the chemical tanker Asana off Yemen in the Gulf of Aden. PortWatch still shows Bab el-Mandeb flowing above trend (41 transits vs 32.3 average), meaning the market has not yet voted with its rudders — but Cape of Good Hope capacity is already running ~18% above average, so the pre-emptive reroute has begun. Meanwhile US enforcement is biting Iranian exports directly: sanctioned tankers laden with Iranian cooking fuel are U-turning and zig-zagging in the Gulf of Oman under an effective US blockade.

Layered on top is a distillate shock: Russia's diesel export ban, after refined-product exports already fell 14% m/m in June to 1.61m b/d, is forcing long-haul clean-tanker demand up and diesel prices higher just as Gulf product flows are impaired. Black Sea risk is also live again — Russian drones killed three and damaged foreign-flagged ships in Ukrainian ports on Friday.

Market read: Crude has repriced (Brent $81.62, +$7.28 on the prior EIA/FRED print) but arguably not for a Bab el-Mandeb closure on top of a throttled Hormuz. The asymmetric trades are long diesel cracks, long tanker tonne-miles (Cape reroutes + long-haul clean substitution for Russian diesel), and war-risk premium on anything calling the Gulf, Red Sea or Ukrainian Black Sea ports.

Read: WTI $79.20 and Brent $81.62 (EIA/FRED, 13 Jul) are up roughly 9-10% from the prior print ($72.45/$74.34) on the escalation. US fundamentals are a partial offset: EIA week to 10 July shows crude stocks drawing modestly to 409.7m bbl, imports steady at 5.69m b/d, and exports jumping to 3.72m b/d (+459k w/w) — US barrels are filling part of the Gulf gap. Henry Hub is quiet at $2.83/MMBtu and gasoline $3.855/gal (FRED, 13 Jul). The sharper story is distillate: Russia's diesel export ban lands on a market where Gulf product exports are impaired and OPEC already called June's tanker market volatile with VLCC rates falling on higher availability — that balance has now flipped, with Affinity noting heightened uncertainty East of Suez. The broad commodity index (FRED, 1 Jun) was still softening pre-crisis at 194.9, so this is a supply-shock rally, not a demand story.

Our terrestrial feed has no live coverage of Hormuz, Fujairah, the Persian Gulf, India West Coast, Bohai or Singapore this window — the Gulf read relies entirely on PortWatch satellite data, which shows the collapse described above. Where we do have live data: Malacca holds 73 vessels (slow/anchored 43, above the 64 baseline — mild congestion, tanker capacity present ~1.7m bbl); the US Gulf shows 333 vessels, right on its 332 baseline, consistent with the strong EIA export number; Rotterdam is dense (281 vessels, ~2.25m bbl of tanker capacity present) with normal operations; Suez live count is thin (4 vs 5.4 baseline) consistent with PortWatch's softening transit count; the Bosphorus live sample (1 vessel vs 6.9 baseline) is too small to read against PortWatch's above-trend throughput. No VLCCs appear in any covered zone and no zone we can see covers the VLCC-relevant Gulf anchorages — we cannot corroborate a Fujairah queue either way and defer to published reporting that Hormuz transits are at a five-week low.

• MARY MAERSK — [ULCV] 399m Triple-E class boxship, Denmark flag, IMO 9619921, moored Rotterdam at 17m draught (near full load), declared next NLROT then OMSLV (Salalah, Oman), ETA 11 Aug. Owner: A.P. Moller-Maersk (fleet vessel; enriched from operator naming — load port not confirmed).
  A Maersk flagship routing Rotterdam→Salalah with a mid-August ETA implies a Cape of Good Hope routing on the Asia-Europe backhaul — consistent with PortWatch's +18% Cape volumes and continued Red Sea avoidance by the major lines.
• LOS ANGELES EXPRESS — [ULCV] 368m boxship, Singapore flag, IMO 9665633, moored Rotterdam, draught 12.9m, bound Wilhelmshaven (DEWVN) ETA 19 Jul. Operator: Hapag-Lloyd Express-class naming (enriched by name pattern; owner registry not independently confirmed — load port: not found).
  North Europe hub rotation running normally — the European end of the Asia-Europe trade is not the bottleneck; the risk sits at the Red Sea/Cape routing decision.
• TAIPAN — Tanker, Marshall Islands flag, IMO 9996393, 274x50m (~1.0m bbl class), draught 9.5m (light for size — likely ballast/part-laden), underway from Rotterdam toward Gibraltar (GI GIB), ETA 23 Jul. Owner/load port: not found (not enriched this window).
  A large tanker leaving Rotterdam in ballast toward Gibraltar is consistent with repositioning toward Atlantic/Med loading — spot tonnage chasing the disrupted East-of-Suez premium or US Gulf barrels.
• MSC AGAMEMNON VIII — Cargo/boxship, 318m, Madeira flag, IMO 9315381, underway US Gulf, draught 11.7m, routing Altamira (Mexico) → Houston, ETA 17 Jul. Operator: MSC (name; enriched from operator naming).
  Transpacific/Gulf feeder loop running normally; US Gulf box operations unaffected by the Middle East crisis so far.
• ASANA (news, not in AIS feed) — Chemical tanker reportedly boarded and seized by armed assailants off southern Yemen in the Gulf of Aden on Friday (maritime security sources via gCaptain).
  First seizure of the new escalation phase in the Aden corridor — whether piracy or Houthi/Iran-linked, it validates INTERTANKO's region-wide threat warning and will push war-risk premia for Bab el-Mandeb approaches regardless of attribution.

Dry bulk is easing: the Baltic Dry Index fell a third straight session to a two-week low of 2,752 (-3.1%), led by capesizes — yet COSCO just ordered four newcastlemaxes for 2029, so owners are looking through the dip. Containers are turning: Drewry's WCI posted its first decline since end-April (Shanghai-Rotterdam -1% to $4,873/40ft, Shanghai-Genoa -3%) with capacity rising into cooling demand; the only bull case is geopolitical (Bab el-Mandeb closure would reverse it instantly). Tankers are the strong leg: Russian diesel disruption is structurally lengthening clean-tanker hauls, and Cape reroutes plus Gulf war-risk premia support dirty rates despite June's VLCC softness. Notable niche signal: Sea Legend restarts China-Europe Northern Sea Route sailings (eight voyages Aug-Oct, 21 days Ningbo-Felixstowe) — the Arctic is becoming a genuine relief valve, underlined by two Chinese icebreakers transiting the Bering Sea.
