Recent indirect US-Iran exchanges through Qatari and Pakistani mediators have continued amid stalled progress on core disputes over the Strait of Hormuz, sanctions relief, and nuclear issues, with Iran reviewing Washington's latest counterproposal as of October 12 and signaling intent to respond via the same channels. These back-channel efforts, including September UN General Assembly contacts in New York and early October Doha meetings, have produced no direct senior-level agreement or breakthrough, supporting trader emphasis on no meeting by year-end. Qatar's active facilitation of proposal swaps and high-level visits positions it as the leading venue option, while Switzerland draws from its record hosting prior technical sessions. Broader uncertainties around escalation risks and mediator roles limit probabilities for other sites.
