New US strike wave on Iran elevates oil supply risk

Summary
CENTCOM reports a fresh wave of coordinated Tomahawk and F/A‑18 strikes on ‘dozens of targets’ in Iran, explicitly aimed at degrading its offensive capability. Coming alongside reports that Iran’s Guards have halted Hormuz transit, this materially raises the probability of prolonged disruption to Gulf crude and product flows and supports a higher risk premium across the oil complex.
Details
CENTCOM has announced completion of another offensive strike wave against Iran using BGM‑109 Tomahawk cruise missiles and F/A‑18 Super Hornets, hitting ‘dozens of targets at multiple locations.’ While target specifics are not fully disclosed, the stated intent is to degrade Iran’s ability to continue attacks, implying a focus on military, command-and-control, and potentially coastal/air assets that underpin its ability to threaten Gulf shipping and energy infrastructure.
This development must be read together with concurrent reporting that Iran’s Revolutionary Guard Corps has suspended transit through the Strait of Hormuz in response to US actions. Even if this ‘halt’ is partial or selectively enforced, the combination of expanded US kinetic operations on Iranian soil and Iranian signaling around Hormuz meaningfully increases the probability of short‑run disruptions to seaborne crude, condensate, and product flows from the Gulf. Roughly 17–18 mb/d of crude and condensate and significant NGL/product volumes normally transit Hormuz; even a perceived risk to 5–10% of those flows is enough to move benchmarks several percent on risk premium alone.
Immediate market impact is a bullish impulse for Brent, Dubai, and related spreads (Brent–Dubai, Brent–WTI), with options volatility skew likely to steepen to the upside. Front‑month Brent could see >2–3% intraday moves on positioning and headline risk, especially given existing alerts of earlier US strikes around Iran’s Abadan oil hub and Iranian missile/naval activity. Gulf producers’ OSPs and prompt physical differentials may begin to reflect higher freight and war‑risk insurance premia.
Natural gas and LNG benchmarks (TTF, JKM) may also catch a bid on generalized Middle East supply risk, though the effect should be smaller than on oil unless there are explicit threats to Qatari LNG shipping lanes. Gold, US Treasuries, and defensive FX (JPY, CHF) tend to benefit in analogous US–Iran escalations (e.g., 2019 tanker attacks, 2020 Soleimani strike), while high‑beta EM FX in the region typically weakens.
The key uncertainty is duration: if this strike wave is followed by some de‑escalation and only limited, symbolic Iranian retaliation, the risk premium may partly mean‑revert over days. However, if Iran maintains a hard line on Hormuz transit or proxies escalate in the Red Sea and Gulf, the impact becomes more structural, supporting a persistently higher geopolitical premium in crude and tanker markets over weeks to months.
AFFECTED ASSETS: Brent Crude, WTI Crude, Dubai Crude, Oman Crude futures, Gasoil futures, Arab Gulf tanker freight (VLCC), Gold, JPY, CHF, US 10Y Treasuries, JKM LNG, TTF Natural Gas
