## Prediction

Over the next 7 days, the pattern of US tanker boardings and Iranian assertion of supervisory control through the Persian Gulf Strait Authority will significantly raise the probability of an incident involving close maneuvers, warning shots, or collision between US and Iranian vessels. Both sides will likely place additional naval and air assets in and around the strait, increasing density and miscalculation risk. However, both Washington and Tehran will remain disincentivized from a full-scale closure of Hormuz due to economic and political costs, resulting in a continued but contested flow of shipping. Any clash is most likely to be brief, localized, and followed by rapid back-channel deconfliction.

## Drivers

- Repeated alerts about US Navy boardings of Iranian tankers and Iran’s formalized demand for transit authorization
- Emerging trend describing US–Iran confrontation shifting into coercive maritime blockade diplomacy
- Fed minutes linking inflation to Iran war, highlighting macroeconomic consequences of a major Gulf disruption
