Roughly 20% of the world's traded oil — and a significant share of global LNG — moves through a corridor just 33 nautical miles wide at its narrowest point. The Strait of Hormuz is not merely a shipping lane. It is a geopolitical pressure valve, and what happens within its waters reverberates immediately in energy markets, supply chains, and the strategic calculus of governments worldwide.

In March 2026, that pressure is being felt more acutely than ever. Amid regional tensions and increased reports of active GPS jamming, the ability to know — with precision — what is transiting the Strait, when, in which direction, and bound for where, has become operational intelligence of the highest order.

SeaVantage has been tracking the Strait continuously, and the data we are publishing today reflects our live monitoring feed over the last seven days and the last 24 hours — a snapshot of real commercial maritime activity in one of the most sensitive waters on earth.

Our seven-day dataset captures 63 individual vessel transits across a diverse fleet profile — crude oil tankers, product tankers, chemical tankers, LPG carriers, bulk carriers, and container vessels. These are confirmed, geo-fence-triggered events: the precise moment each vessel crossed into or out of our designated Strait of Hormuz monitoring zone.

The sample below from our live dashboard illustrates the breadth of traffic and the richness of the data layer — vessel type, nationality, transit direction, ETA, and declared destination. Full IMO numbers and vessel identities are available in their entirety to platform subscribers.

What stands out in the seven-day data is the sheer diversity of cargo and destination profiles. Iranian-flagged bulk carriers transiting outbound. LNG carriers bound for Singapore. Product tankers declared "FOR ORDERS" — a classic indicator of vessels awaiting last-minute cargo instructions, often associated with opaque trading chains. A food cargo consigned to Iran via a Marshall Islands-flagged vessel. Each of these data points tells a story that a commodity trader, a freight broker, a risk desk, or an insurer needs to understand.

In the last 24 hours, our platform recorded five vessel transits through the Strait — a figure that, while lower than the daily average across the week, reflects the inherent variability of maritime traffic patterns and the continued operational reality that this route has not been closed.

The 24-hour snapshot contains several noteworthy data points. One crude oil tanker flying an Antigua & Barbuda flag is heading outbound with a destination listed as "CHINESE OWNER & CREW" — a signal for potential dark-fleet activity deserving of closer scrutiny. Another tanker is inbound with destination "TO ORDER." An Emirati product tanker shows an ETA in October 2026 — almost certainly a data artefact or placeholder, but worth noting as a quality-control indicator that our team monitors closely.

The data above is drawn from SeaVantage's dedicated Strait of Hormuz 24/7 Live Monitoring Dashboard — a platform built for professionals who require not just data, but answers. Here is what our monitoring infrastructure delivers:

The Strait of Hormuz has never been a passive corridor. But in the current environment — with ongoing regional tensions, confirmed GPS jamming operations, and the persistent presence of vessels connected to sanctioned entities — the cost of operating without real-time transit intelligence is measurably higher than it has been in years.

For energy traders and commodity desks, knowing what tankers are moving — and in which direction — is a leading indicator for regional supply tightness before it shows up in price screens. For P&I clubs and marine insurers, zone-crossing events are the foundation of war-risk and deviation analysis. For compliance and sanctions teams, vessels declaring "FOR ORDERS," showing implausible ETAs, or flying flags of convenience through sensitive zones require immediate scrutiny. For port operators and terminal planners from Fujairah to Sohar to Karachi, inbound vessel flow through the Strait is the earliest signal in their arrival pipeline.

SeaVantage was built to answer that question. Our platform does not aggregate publicly available AIS fragments and call it intelligence. We apply proprietary geo-fence logic, cross-validated positioning data, and structured event taxonomy to deliver authoritative, actionable signals — at the vessel level, in real time, around the clock.
