Will the United States and Iran reach a formal nuclear agreement by the end of Q4 2026?
What moved
The US struck Larak Island in the Gulf; Iran vowed a decisive response with no stated action or timeline.
The market transmission
A first strike in weeks breaks a period of relative restraint and raises the probability of Iranian escalation, but 'vow' is a statement, not an action. The path into oil prices depends on whether Iran retaliates through direct attack on infrastructure or through proxies in shipping lanes. Until that happens, the market is pricing the probability of escalation rather than a disruption itself.
What would change this
A casualty count from a US strike is newsworthy but not a repricing signal by itself; the market reprices on Iran's actual response, not its rhetoric. The Gulf has absorbed strikes and threats for years without sustained supply disruption. Severity rises sharply only if Iran targets export terminals, tanker traffic, or the Strait of Hormuz itself.
