Iran retaliates after Larijani killed, strikes US assets and Israel

Iran intensified missile and drone strikes against U.S. regional assets and Israeli targets after Israeli forces announced the killing of Iran’s security chief Ali Larijani on March 17, 2026. Israeli statements and regional reporting said several senior Iranian security figures were targeted overnight, prompting an immediate Tehran response.

According to on-the-ground and international reporting, the Israeli operations hit selected facilities in Tehran and elsewhere; Iranian forces countered with attacks on bases and infrastructure in the Gulf and Levant, and incidents affecting commercial shipping were reported in and around the Strait of Hormuz. U.S. and allied commands confirmed heightened activity and defensive measures in the region.

Financial markets reacted quickly to the escalation: Brent and WTI crude futures surged, briefly trading above the $100-per-barrel level as supply-route risk spiked, while safe-haven flows lifted gold and pressured cyclical equities. The energy sector outperformed on the upside, but broader equity indices experienced elevated volatility as traders priced geopolitical risk into asset valuations.

In the wider economic context, sustained disruptions in Gulf shipping and production risk feed through to global inflation and trade costs, complicating central bank policy choices. Even if coordinated releases from strategic petroleum reserves are deployed, analysts warn such measures may only partially offset supply-side concerns while systemic risk premia remain elevated.

Market strategists say near-term outlook hinges on the scale and duration of reprisals: a contained exchange may see transient price spikes and a quick normalization, whereas prolonged targeting of shipping lanes or major facilities could embed higher inflation expectations and force re-pricing across fixed income and equity markets. Recommended investor actions include reassessing energy exposure, tightening hedges on commodity and FX risk, and prioritizing liquidity to navigate episodic volatility.
