**Summary**: The IRGC reportedly fired three anti-ship cruise missiles at an ‘enemy ship’ in the Indian Ocean, coinciding with a UKMTO alert of ‘military interaction’ with a merchant vessel east of Duqm, Oman. This marks a geographic widening of Iran-linked attacks beyond the Gulf chokepoints, supporting a higher risk premium on seaborne crude and product flows.

## Detail

1) What happened:
Iran’s IRGC is reported to have launched three anti-ship cruise missiles at an unspecified ‘enemy ship’ in the Indian Sea/Indian Ocean area. Around the same time, UKMTO reported a merchant vessel experiencing ‘military interaction’ roughly 100 nm east of Duqm, Oman. While details on damage, flag, and cargo type remain unclear, the event indicates the use of anti-ship missiles rather than only drones or small boats, and in waters that are a key transit zone for traffic from the Gulf to Asia and Europe.

2) Supply/demand impact:
Even absent confirmed physical damage, the use of anti-ship cruise missiles elevates perceived risk to commercial shipping, particularly tankers and potentially LNG carriers transiting the Arabian Sea and approaches to the Gulf of Oman. Insurers are likely to reassess war risk premia for voyages through this broader area, pushing up freight rates. A 5–15% uptick in war risk premiums on certain routes is plausible if this behavior repeats, which can translate into several tens of cents per barrel in effective delivered cost. While there is no direct loss of supply yet, higher risk and insurance costs tend to be priced into crude benchmarks via higher risk premia, especially for Middle Eastern grades and Brent.

3) Affected assets and direction:
Bullish for Brent and Dubai benchmarks and for regional freight indices (especially VLCC and Suezmax routes from AG to Asia and Europe). LNG shipping rates out of Qatar and Oman may also see a risk bid. Safe-haven assets like gold and the USD versus regional currencies can attract flows if the incident is read as escalation in the broader Iran–US/Gulf confrontation.

4) Historical precedent:
Past IRGC-linked attacks on tankers in the Gulf of Oman and off Fujairah (2019) produced ~1–3% one-day moves in oil benchmarks and sustained higher war risk insurance costs, even with limited physical damage and no long-term supply loss.

5) Duration:
If this remains a single, contained incident, impacts are likely to be short-lived (days). However, in the context of ongoing missile and drone exchanges between Iran and the US/Gulf states, markets may embed a persistent geopolitical premium on AG-origin crude and related tanker routes.

**AFFECTED ASSETS:** Brent Crude, Dubai Crude, Middle East crude differentials, Tanker freight indices (AG–Asia, AG–Europe), LNG shipping rates (Qatar/Oman), Gold, USD index
