Turkey and Iran talk Hormuz as Saudi attacks and BRICS-style mediation reshape the chessboard

On 2026-09-12, Turkish Foreign Minister Hakan Fidan held a phone call with his Iranian counterpart Abbas Araghchi, focusing on regional security concerns. The discussion explicitly covered the Strait of Hormuz, broader conflict dynamics in the region, and attacks carried out against Saudi Arabia. The call signals active backchannel diplomacy at a moment when maritime chokepoints and proxy-linked violence are again converging in the same risk narrative. While the articles do not provide operational details, the choice of topics indicates that Ankara and Tehran are aligning on how to manage escalation risks around Hormuz and Gulf stability. Strategically, the cluster points to a diplomacy contest over who can shape outcomes during an “Iran crisis,” with mediation ideas stretching from BRICS-linked channels to regional hubs such as Oman. Turkey’s engagement with Iran on Hormuz matters because it sits at the intersection of NATO-adjacent security concerns and Gulf energy transit risk, giving Ankara leverage in crisis messaging. Iran benefits from diplomatic insulation and from keeping the Hormuz issue from becoming a purely Western-led containment frame, while Saudi Arabia faces reputational and security pressure tied to attacks attributed to regional instability. Europe’s “rearranges the diplomatic deckchairs” framing suggests that European governments are also recalibrating priorities amid global crises, potentially affecting sanctions posture, naval risk management, and diplomatic bandwidth. Market implications center on energy transit risk and the probability of shipping disruptions around Hormuz, which can quickly reprice crude and refined products expectations. Even without quantified figures in the articles, the direction of risk is clear: higher perceived escalation risk typically lifts risk premia in oil-linked instruments and increases volatility in shipping insurance and freight rates. If attacks on Saudi Arabia and Hormuz-related concerns intensify, the most sensitive exposures would be Gulf-linked crude benchmarks, tanker routing costs, and regional gas and power hedging strategies. For investors, the likely transmission mechanism is not only spot price moves but also changes in forward curves and volatility skews tied to geopolitical risk. What to watch next is whether the Turkey–Iran phone diplomacy produces follow-on statements, coordination on maritime deconfliction, or signals to reduce the probability of retaliatory cycles. On the mediation front, track whether BRICS-to-Oman-style efforts gain concrete participation from key Gulf and Western stakeholders, or remain at the level of commentary. For markets, the trigger points are any escalation in attacks associated with Saudi Arabia, any new disruptions or warnings affecting Hormuz shipping, and any European policy shifts that alter sanctions enforcement or naval posture. A near-term escalation window is implied by the immediacy of the phone call and the “new diplomacy” narrative, while de-escalation would be indicated by sustained quiet around Gulf incidents and credible mediation milestones.

Geopolitical Implications

• 02

  Iran gains diplomatic insulation by engaging on Hormuz risk management rather than facing a purely Western containment frame.

• 03

  Saudi Arabia faces heightened pressure as referenced attacks raise the risk of retaliatory cycles and broader Gulf instability.

• 04

  BRICS-to-Oman mediation narratives indicate competition over diplomatic legitimacy and may complicate Western-led processes.
