Explosions have been heard in Riyadh, Sabereen reports

Reports of explosions in the Saudi capital sit in a familiar category of mid-conflict signal: unverified detonations reported via a regional outlet, with attribution, target and scale all unknown at first wire. The sourcing matters here, since the reporting channel is affiliated with one side of an active regional confrontation, and past episodes of this kind have included both confirmed strikes and incidents that were later walked back, downgraded to air-defence interceptions, or left unconfirmed entirely. Comparable episodes have tended to resolve quickly into one of three cases: a projectile reaching the city, a successful interception with debris on the ground, or a false or unconfirmed report, and the market pattern differs accordingly, since interceptions and false reports have historically produced short-lived risk-off moves while confirmed strikes on sovereign or energy infrastructure have held. The channels to watch are crude, where Saudi supply security premia respond to any confirmed hit on energy assets, and Gulf-linked FX and credit. The follow-ons that matter are official Saudi confirmation, the nature of the target, and whether a claimant emerges, since attribution determines the retaliation and escalation calculus. Until confirmation, the report is noise with a fat tail rather than signal.
