Will the United States and Iran reach a formal nuclear agreement by the end of Q4 2026?
What moved
Iran attacked US bases in Jordan after US strikes on Larak Island; the flare-up is the first since late July and adds near-term uncertainty around Iran sanctions enforcement and regional oil transit risk.
The market transmission
Direct physical conflict between the US and Iran remains low-probability and escalation is not assured, but the exchange breaks a two-month calm and resets risk perceptions around Hormuz transits and crude supply. The Strait carries roughly a fifth of seaborne oil; a sustained closure would reprice energy markets sharply, but temporary disruptions or heightened insurance and escort costs are the more likely near-term channel. Real rates remain elevated, which dampens the traditional safe-haven bid in gold.
What would change this
Tit-for-tat strikes do not establish a trajectory; the fact that this is the first exchange since late July suggests a cycle of tension with pauses rather than a march toward sustained closure. Spare crude capacity is adequate globally but regional refining margins can shift sharply on Hormuz anxiety. Gold does not automatically rise in conflict when real rates are high and the yield on Treasury paper competes with the safe-haven trade.
