## Prediction

Over the next 30 days, cumulative incidents around Hormuz and Gulf bases make a limited but direct naval clash between US and Iranian forces—such as exchange of anti‑ship missiles, close‑range gunfire, or disabling of an IRGC vessel—plausible. Both sides will try to calibrate actions below all‑out war, but a single lethal miscalculation involving US sailors or Iranian crews could force much stronger retaliation. Such a clash would immediately threaten 20%+ of global oil flows and could trigger emergency IEA coordination. Confirmation would be progressive escalation in size and proximity of incidents, culminating in acknowledged kinetic contact; denial would involve a robust de‑confliction channel and visible reduction in Iranian maritime harassment.

## Drivers

- Projectile hit on vessel near Al‑Khasab and multiple Iran‑linked shipping attacks
- Suspected Iranian drone and missile strikes against Kuwait and US base
- Iranian threats to attack US warships and block non‑Iranian shipping corridors
- Emerging trend of Iran–US confrontation shifting to blockade and drone coercion
