Entrenched Low-Intensity U.S.–Iran Confrontation in Gulf With Periodic Flare-Ups
Theater: Strait of Hormuz

Moderate confidence (60%)
Risk direction: volatile · Impact: CRITICAL
Executive summary
Over the next 30 days, the U.S.–Iran confrontation in the Gulf is likely to settle into an entrenched low- to medium-intensity conflict, marked by intermittent missile tests, drone incidents, and IRGC harassment of shipping, punctuated by occasional sharp flare-ups when incidents cross red lines. A formal ceasefire at sea is unlikely even if nuclear and financial understandings progress on land. Both sides will harden regional basing and air defense networks, and Iran will continue to use quasi-legal tools like ‘environmental fees’ to exert control over shipping. Risk of a miscalculation leading to a significant naval loss or serious tanker damage will persist throughout.
Key indicators we're watching
- Existing pattern of reciprocal strikes and missile launches in Hormuz and Gulf of Oman
- Emerging trend of US–Iran de-escalation that remains conditional and incomplete
- Iran’s institutionalization of IRGC involvement in shipping via ‘environmental protection’ charges
- Historical endurance of similar tense maritime stand-offs (e.g., 1980s tanker war, 2019–2020 incidents)
