Supply Chain & Chokepoints
Panama · Suez · Red Sea / Bab-el-Mandeb · Hormuz. Each chokepoint pairs live weather (where a key is configured) with the operational implication for ton-miles, fleet supply and bunker demand. Flow/congestion analytics are commercial (Tier-4 stubs ready).
Panama Canal
Flows: US Gulf ↔ Asia LPG/LNG, containers, grains, some clean products.
Why it matters: Draft restrictions during drought cut transits and slot availability, forcing longer Cape Horn / Suez routings that lengthen voyages and lift bunker demand per cargo.
Operational implication: Reduced daily transit slots → waiting time, auction premiums, and ton-mile inflation. Watch ACP draft/booking notices.
Watch: ACP transit & draft advisories; Gatún Lake level.
Suez Canal
Flows: Europe ↔ Asia crude, products, containers; ~10–12% of world seaborne trade in normal times.
Why it matters: Diversions around the Cape of Good Hope add ~10–14 days each way Asia–Europe, raising ton-miles, tying up tonnage, and increasing bunker burn — supportive for freight and bunker demand.
Operational implication: Re-routing absorbs vessel supply (tighter effective fleet) and changes bunkering hubs (more Singapore/Mauritius/West Africa stems).
Watch: SCA transit counts; Red Sea security advisories.
Red Sea / Bab-el-Mandeb
Flows: Gateway between Suez and the Indian Ocean; tankers, containers, LNG.
Why it matters: Security risk here is the proximate driver of Suez avoidance. War-risk insurance (AWRP) and crew-risk premiums spike; many owners reroute regardless of canal capacity.
Operational implication: Higher insurance, convoy/transit decisions, and a structural Cape re-routing premium embedded in freight.
Watch: War-risk premiums; naval coalition advisories; carrier routing statements.
Strait of Hormuz
Flows: ~1/5 of global oil & much LNG (Qatar) exits the Gulf here. Fujairah bunkering hub sits just outside.
Why it matters: The single most concentrated oil chokepoint. Any closure threat reprices crude, tanker risk, and Gulf bunker supply almost instantly.
Operational implication: Tension → VLCC rate & war-risk spikes, Fujairah premium, and potential rerouting of Gulf crude.
Watch: Gulf tension headlines; Fujairah bunker availability; AGI (Arabian Gulf) VLCC fixtures.
Beyond weather: live transit counts, AIS congestion and floating-storage analytics are commercial/enterprise (Kpler, Vortexa, MarineTraffic, Signal Ocean). Their Tier-4 adapters are stubbed and will populate this section when licensed — no figures are fabricated in the meantime.
