Will the United States and Iran reach a formal nuclear agreement by the end of Q4 2026?
What moved
U.S.-Iran attacks escalated; global equities fell, oil rose sharply and bond yields returned to pre-intervention highs.
The market transmission
The escalation lifted oil prices on immediate supply-risk perception in the Gulf, where roughly a fifth of seaborne crude transits daily with no maritime alternative. Equities sold on risk-off positioning and the prospect of wider regional instability. Bond yields rose as markets repriced away expectations of near-term rate cuts, reversing recent intervention-driven declines. The mechanism is straightforward but magnitude and durability depend on whether this is tactical or signals a broader shift in U.S.-Iran confrontation.
What would change this
The signal reports market moves, not the underlying attack details, so the severity of the escalation and the likelihood of direct supply disruption remain unstated. Yields rising on risk-off can compete with safe-haven flows; the fact that bonds sold rather than bid suggests equity liquidation and duration unwind dominated the risk repricing. Oil's sharp move reflects immediate Gulf supply concern, but without stated production outages or Hormuz transit disruption, the move is perception-driven rather than flow-driven.
