Z20100 – [CL] Strait of Hormuz Tanker Transit

The Strait of Hormuz is the single most important oil chokepoint in the world: a 21-mile-wide waterway between Iran and Oman through which approximately 21% of global seaborne crude oil (roughly 17-18 MMBPD) transits daily. All GCC crude exports (Saudi Arabia, UAE, Kuwait, Qatar, plus Iranian + Iraqi exports) flow through Hormuz. Any disruption, Iranian naval action, Iran-US military confrontation, Iranian internal instability, mining of the strait, would immediately drive crude prices $20-$40 per barrel higher. The strait is simultaneously the greatest geopolitical risk and the most reliable supply artery in the global oil market. this signal reads daily tanker transit through Hormuz, likely sourced from AIS vessel tracking + port call manifests + IHS Markit shipping intelligence. The signal measures flow level: elevated flow = base case normal transit, declining flow = potential disruption event, surging flow = ramp-up (perhaps anticipating cap on future exports). Native +1 polarity in CL NG Cross-Market Coupling composite. this signal is a 20% weight member of CL NG Cross-Market Coupling, companion to EIA Natural Gas Exports Monthly EIA NG exports anchor (40% top), the companion signal CAD weakness proxy (25%, -1 polarity), and the companion signal credit GIRF context (15%). this signal’s role in CL NG Cross-Market Coupling is likely as HORMUZ-SPECIFIC supply confirmation signal: when Hormuz transit normal + NG exports expanding + CAD stable, CL NG Cross-Market Coupling reads BULL (current state). When Hormuz flow disrupts, CL NG Cross-Market Coupling would flip toward BEAR via supply-shock premium. Note: this signal is Hormuz-specific while CL Chokepoint Tanker Flow (used in CL PORTWATCH Chokepoint at 100% weight) aggregates Hormuz + Suez + Bab-el-Mandeb + Cape of Good Hope into a broader chokepoint composite. CL NG Cross-Market Coupling uses the more targeted Hormuz signal while CL PORTWATCH Chokepoint uses the aggregate. Different design choices.

What the chart is showing. The dark line in the top panel is the Hormuz tanker-transit composite on a tanh-bounded plus-or-minus one scale — positive means elevated tanker flow through the strait (bullish WTI via strong demand), negative means subdued flow (bearish or disruption signal). The bronze line in the middle panel is the NYMEX WTI Crude front-month in dollars per barrel. The bottom panel tracks the 252-day rolling information coefficient between the composite and WTI 60-day forward returns. Dashed horizontal lines mark the plus-or-minus 0.2 moderate and plus-or-minus 0.5 extreme thresholds.

THE TRANSIT CALL

Composite +0.000, state Disruption Building, 41 trading days running. Current direction and per-state baselines are in the regime table below.

THE EMPIRICAL CONTEXT

Per-state forward returns show a cleanly monotone pattern in the regime table — High Transit is the bullish regime, Low Transit the bearish, Normal in between. The empirical direction treats transit as a coincident demand/flow indicator rather than a geopolitical-risk gauge; a disruption event would show up as rapidly declining transit from an elevated reading.

THE HONEST CAVEAT

Hormuz is the primary geopolitical tail risk in global crude; an Iranian action or Iran-US military confrontation would drive a sharp transit collapse and 20-40 dollar per barrel crude spike that would not be captured by the 60-day forward-return framing used here. Use alongside geopolitical-risk sentiment and GCC production data.
