Trade & maritime brief — Wednesday, 29 July 2026

• Red Sea / Bab el-Mandeb: Houthis claim a fourth attack on a Saudi-linked tanker under their declared blockade of Saudi ports; PortWatch shows Bab el-Mandeb transits at 20 vs 28.1 7-day average and cargo capacity ~26% below trend — the blockade is measurably biting, though liners logged 54 boxship transits last week. Price Saudi Red Sea calls at max war-risk; expect further Cape diversions and bunker surcharges.
• Hormuz / Gulf crude: Oman's Gulf-backed plan for voluntary Hormuz transit fees plus Trump restraining Israel from Iranian energy targets is bearish-tilting for crude (oil extended losses on the news), but PortWatch shows Hormuz cargo capacity as of Jul 23 at roughly a third of its 7-day average — physical flow remains impaired. No free-AIS coverage of the strait; rely on PortWatch and published data.
• Iranian barrels / China demand: Iranian crude is stacking up off eastern Malaysia as Chinese teapots stay sidelined despite deeper discounts; Kpler puts July China seaborne imports rebounding to ~7.8 mb/d (from 6.2 in June) while Vortexa sees only 6–7 mb/d — the rebound is largely delayed Gulf cargoes arriving, not fresh demand. Discounted-barrel availability stays high.
• Container / freight: CMA CGM posted strong Q2 on disruption-inflated rates and closed the $2.4bn Stonepeak United Ports JV; SCFI has fallen three straight weeks (peak season apexed early) but carriers are layering new Middle East bunker surcharges ($150/teu dry from Aug 1 on CMA CGM India trades). Book Q4 mini-peak capacity early.
• Black Sea / grain: Russia proposing to arm Azov Sea grain ships against Ukrainian drones, and the Caspian is no longer a sanctuary after Kyiv's strike on an Iranian vessel — war-risk premia are spreading to basins underwriters priced as safe. Bosporus transits (57 vs 63.9 avg, tanker cap ~91% below trend on the day) also soft.
• US tariffs: Threatened 50% US tariffs on Canada and far-reaching Section 301 actions keep tariff volatility elevated; plan for front-loading and re-routing rather than assuming legal relief.

Escalation · Red Sea & Hormuz

Houthi blockade of Saudi ports bites as Oman floats a fee-based Hormuz off-ramp

The two Middle East chokepoints are moving in opposite directions. In the Red Sea, the Houthis claimed a fourth attack on a Saudi-linked tanker since declaring a maritime blockade of Saudi ports on July 20, and Yemen's top diplomat explicitly framed the strategy as replicating Iran's Hormuz leverage at Bab el-Mandeb. The data confirms the squeeze: IMF PortWatch (Jul 26) shows 20 Bab el-Mandeb transits against a 28.1 seven-day average, with cargo capacity ~814kt vs a ~1,103kt trend. Yet the blockade is selective — Linerlytica tracked 54 containership transits in a week, with Maersk, CMA CGM and Wan Hai still serving Jeddah — so the acute risk is concentrated on Saudi-linked tanker tonnage, exactly the class being hit.

At Hormuz, the signal is tentative de-escalation: Oman has presented Iran with a Gulf-backed plan to manage the strait including voluntary transit fees, and Trump is reported to be restraining Israel from striking Iranian energy assets — oil extended losses on the news. But the physical flow has not normalized: PortWatch (as of Jul 23) shows Hormuz cargo capacity at ~61kt against a ~182kt seven-day average, with tanker transits below trend and zero tanker capacity recorded in the latest reading. Our live AIS has no Hormuz/Fujairah/Persian Gulf coverage this window, so no VLCC queue read is possible from our feed; the PortWatch deficit plus tight Singapore VLSFO (16–20 day lead times, per ENGINE) says the disruption premium in freight and bunkers is still very much live even as flat price softens.

Market read: Bearish-tilting flat price (Brent $86.99, WTI $84.38, FRED Jul 20 — before the Oman-plan selloff) against firmly bullish tanker ton-miles, war-risk premia and bunker costs. Fade crude spikes on diplomacy headlines; stay long freight disruption.

Read: Crude is caught between softening headlines and hard physical friction. FRED marks Brent at $86.99 and WTI at $84.38 (Jul 20), with prices extending losses this week on the Oman Hormuz fee plan and Trump's restraint of Israel. US fundamentals lean bearish: EIA week to Jul 17 shows crude stocks building 2.0m bbl to 411.7m, imports up to 5,806 kb/d and exports down to 3,353 kb/d — the US pulling in more and shipping out less. Meanwhile the discounted-barrel overhang grows: Iranian crude idling off eastern Malaysia as Chinese independents hold back despite deeper discounts, and China's July import rebound (Kpler ~7.8 mb/d vs 6.2 in June; Vortexa lower at 6–7 mb/d) is mostly delayed Gulf cargoes landing, not new buying. Henry Hub sits at $2.80. The cost side is where the bull case lives: Singapore VLSFO lead times out to 16–20 days, carriers imposing $150/teu emergency bunker surcharges, and Peninsula warning of a Cape-diversion 'perfect storm' colliding with Mediterranean ECA rules.

Live coverage this window is 7 of 17 zones — no free-AIS at Hormuz, Fujairah, the Persian Gulf, Singapore, India West or Bohai, so no VLCC count is possible there (PortWatch fills the strait gap; note zero VLCCs appeared in any covered zone). Where we do see: US Gulf Coast is busy but normal (432 vessels vs 422.5 baseline, ~7.65m bbl tanker capacity present, destinations dominated by Houston/Port Arthur/Beaumont/Corpus — consistent with EIA's higher import week). Malacca is quieter than baseline (65 vs 90.5, slow/anchored 29) with only ~0.75m bbl tanker capacity in frame — the Iranian floating-storage cluster sits east of our box. Rotterdam shows 327 vessels with ~6.2m bbl tanker capacity and two ULCVs alongside — Europe's import machinery running normally. China South (Pearl) is below baseline (72 vs 88.8). Stale reads: Suez (24h old) showed 14 vessels with slow/anchored triple its baseline; Bosphorus (48h old) showed 9 of 12 vessels anchored with ~3m bbl of tanker capacity waiting, several 'for orders' — consistent with the soft Bosporus transit count.

• MARAN PYTHIA — Suezmax crude tanker (275m, ~1.0m bbl), Greek flag, IMO 9402902, draught 15.3m — near loaded marks — moored Rotterdam. Operator Maran Tankers Management (Angelicoussis), registered owner Boschetto Maritime Inc, Athens (enriched: VesselFinder/Marine Vessel Traffic). Load port: not confirmed this voyage.
  A laden suezmax discharging at Rotterdam is Europe's seaborne crude supply chain functioning normally despite Middle East friction.
• COSCO SHIPPING ALPS — [ULCV] 366m mega-boxship, Hong Kong flag, IMO 9757864, draught 14.7m (deep-laden), moored Rotterdam — COSCO's Asia–Europe loop (line identified by name; owner search not run).
  Deep-laden Asia–Europe ULCV arrivals at Rotterdam corroborate PortWatch's picture of continued (if selective) Suez/Cape box flow.
• NEW YORK EXPRESS — [ULCV] 366m mega-boxship, Liberia flag, IMO 9501332, moored Rotterdam at 10.4m draught, prior call Aarhus (DKAAR) — Hapag-Lloyd 'Express'-class by naming (flag if ambiguous: high confidence but not independently verified this session).
  North Europe feeder rotation running normally; no sign of Rotterdam box congestion (port at baseline).
• TRIDENT 9 — Suezmax-size tanker (274m, ~1.0m bbl), Marshall Is flag, IMO 9241607, draught 14m — laden — underway for Chennai, India East Coast. Owner/load port: not found (not enriched this session).
  A laden crude carrier into Chennai is a direct data point for India's sustained seaborne crude pull on the east coast.
• XIN LONG YANG (news, not in AIS frame) — Chinese VLCC carrying Saudi crude that reversed course toward Suez rather than cross into the Houthi blockade zone, with two more tankers following (Hellenic Shipping News).
  Concrete evidence the Saudi blockade is rerouting laden VLCCs — ton-mile inflation and Saudi Red Sea export friction, precisely the VLCC behavior our blank Gulf feed cannot show.

Dry bulk is easing — the Baltic Dry fell 1.2% to 2,664, lowest since Jul 2, with Capesize off 1.4% — even as 1H iron ore loadings grew (Banchero Costa). Containers: the SCFI has declined three straight weeks, confirming an early peak-season apex, but the Loadstar flags a Q4 mini-peak as 'a new baseline'; CMA CGM's strong Q2 shows disruption is still carrier-accretive, and new Middle East bunker surcharges land Aug 1. Tankers: war-risk is the story — four Saudi-linked tankers attacked, the Caspian added to the threat map by Ukraine's drone strike on an Iranian vessel, and Russia proposing machine guns and missile launchers on Azov grain ships. Underwriters are repricing basins previously assumed safe; expect widening AWRP spreads for Saudi Red Sea and Black Sea/Azov calls. Newbuilding stays hot across bulk, tanker, container and gas (incl. a Ditaş suezmax pair at DH Shipbuilding), and Korea–US shipbuilding cooperation deepened with the KUSPC launch under the $150bn MASGA initiative.

• Whether Iran accepts or rejects the Oman/Gulf voluntary-fee Hormuz plan — the single biggest swing factor for crude and tanker rates.
• Fifth Houthi attack or first sinking of a Saudi-linked tanker; watch whether the blockade widens beyond Saudi-linked tonnage to container services still transiting.
• Next PortWatch update on Hormuz (weekly): does cargo capacity recover toward the ~182kt trend or stay at ~1/3?
• China August crude buying: do teapots re-enter for the discounted Iranian barrels stacked off Malaysia (Kpler vs Vortexa import estimates converging)?
• Aug 1 implementation of CMA CGM's emergency bunker surcharges and whether Maersk/MSC follow — plus SCFI direction for the Q4 mini-peak thesis.
• Singapore VLSFO lead times (16–20 days) — further tightening would signal the bunker squeeze becoming a binding constraint east of Suez.
