Strait of Hormuz Monitoring: Beyond April Fool’s Day

Simple AIS monitoring is no longer sufficient. On April 1st, the market - perhaps coincidentally - attempted to "fool" analysts with a surge of bad data. While we already employ four distinct filtering techniques, this latest anomaly allowed us to develop and integrate a fifth filter. Our system is designed to process raw data, identify emerging spoofing patterns, and rapidly deploy new rules to eliminate false positives. We validate these filters by benchmarking them against pre-crisis baselines.

Filter Impact:

• Pre-crisis: The new filter removed only 0.4% of data (minimal impact on clean traffic).
• Post-crisis: It removed ~22% of false positives (74 of 334 recorded since March 1, 2026).
• April 1 Peak: Before the fifth filter, the false positive rate hit a staggering 46%.

April 1 Deep Dive

Of the 26 crossings reported that day, 12 (46%) were confirmed spoofs. These followed a specific signature: all were outbound, stationary vessels utilizing "position teleportation."

The SynMax Advantage

Our monitoring system is unique in its ability to process vessel crossings, validate authenticity, and proactively filter out noise. We offer an hourly viewpoint, providing you with actionable intelligence long before the rest of the market reacts.

As former commodity traders and fundamental analysts, our focus remains on supply and demand dynamics, not the intricacies of vessel politics. We prioritize the fundamentals that move markets.

Crisis Statistics (Since March 1, 2026)

After applying SynMax’s proprietary 5-step AIS spoofing filter, we have recorded 260 vessel crossings by 236 unique vessels.

• Traffic Collapse: This represents a 93.6% decline from the pre-crisis average of 107.6 crossings/day to just 6.8 crossings/day.

• The "Spoof" Factor: The filter successfully removed 74 false positive crossings from 68 vessels exhibiting spoofing signatures (position teleportation, "heading=511" codes, and near-zero speed anomalies). Without this filter, reported counts would be inflated by 22%.
• Flow Dynamics: Traffic is currently dominated by outbound departures (163 crossings) versus inbound arrivals (59 vessels), reflecting a mass exodus from the Persian Gulf. Only 18 vessels have completed a full round-trip.

• Recovery Signals: A tentative recovery emerged in late March, with weekly averages climbing from 2.9/day (Week 3) to 11.0/day (Week 5).

Market Outlook

A return to normalized shipping volumes appears increasingly unlikely in the near term, contradicting earlier market assessments. As global commodity markets remain tethered to Hormuz traffic, the SynMax Strait of Hormuz platform provides the hourly granularity required to track these shifts before they are priced in.
