## Prediction

In the next 24 hours, additional crude and product tankers are likely to either go dark or use evasive routing through or near the Strait of Hormuz, increasing congestion and collision risk in a high-threat environment. Iranian naval and IRGC elements will continue to assert presence and possibly conduct boarding or inspection attempts under the guise of security or sanctions enforcement. U.S. and allied vessels will maintain a high state of readiness and aggressive ISR postures, raising the chance of tactical misinterpretation during close passes or interference with commercial traffic. While a deliberate, large-scale kinetic strike on a tanker is unlikely within 24 hours, a minor collision, warning-shot incident, or temporary seizure of a single vessel is plausible and would have outsized signaling effects. Such an incident could quickly feed back into political decision-making in Washington and Tehran, raising the odds of escalation over the following week.

## Drivers

- Multiple reports of tankers transiting Hormuz with AIS off amid Iranian attack fears
- Iran’s announcement of a new system in the Strait and large naval group off southern Iran
- US confirmation of nuclear-armed submarine presence and emerging trend of militarized contest over Hormuz traffic
- Persistent closure and elevated tension around the chokepoint described in warnings
