Explosion heard near Zahedan's Jomhuri Boulevard, Tehran, Iran, Fars reports; The source of this sound has not yet been determined

The market pattern in comparable episodes has been an immediate, mechanical risk premium in crude, with the move sustained only when the follow-up reporting ties the event to energy infrastructure, senior personnel, or cross-border escalation; blasts that resolve as domestic incidents have historically seen the premium retrace within the session. The location detail matters more than the noise: incidents in Sistan-Baluchestan in the southeast carry a different read-through, a history of insurgent and border-related violence, from anything in or around the capital, and the headline's geography is itself muddled, which argues for caution on the source. Fars has form for reporting fast and revising later, so the first framing rarely survives contact with subsequent statements. The tells are whether IRGC or official channels issue an attribution, whether the event is claimed, and whether any second blast or retaliation follows. Absent confirmation of any of those, precedent is for the headline to fade.
