Russia has been secretly helping Iran develop advanced supersonic cruise missiles, according to FT.

Reporting of covert military technology transfers between Russia and Iran fits a pattern that has been building through the conflict period: cooperation has tended to flow in both directions, with Tehran supplying drones and munitions and Moscow reciprocating with air defence, satellite, and missile know-how. Supersonic cruise missile assistance would mark a step up from prior transfers, since such systems directly threaten Gulf shipping lanes and regional air defences, which is where the oil risk premium historically attaches rather than to the transfer itself. Attribution matters here: single-source intelligence-based reporting of this kind has often preceded official confirmation or sanction designations, but has also on occasion been walked back or left unverified. The established sequence in comparable episodes is a diplomatic denial, then scrutiny of whether Western governments act on the claim through sanctions on the entities involved, which is the channel that touches actual crude and refined product flows. Worth noting is the distinction between technology transfer and finished hardware: the former implies a longer runway before capability changes hands and a slower market response. Near-term tells are any corroboration from other governments, movement in Gulf war-risk insurance and freight, and whether Israel or Gulf states respond in ways that raise the probability of escalation around Hormuz.
