IRGC Warns Iran Could Resume Hormuz Closure If Nuclear Talks Fail; Saudi Arabia Watches Anxiously

IRGC General Rezaei declared on May 30-31 that Iran is prepared to resume attacks on shipping and reimpose the Hormuz closure if President Trump 'betrays' the nuclear negotiations that produced the May 29 ceasefire. White House Deputy Chief of Staff Stephen Miller had simultaneously claimed that Iran had made significant concessions including agreeing in principle to Hormuz reopening. The IRGC warning placed Saudi Arabia in a precarious position: having weathered the Q1 2026 budget deficit of SAR 125.7B and suppressed oil production to 6.77M bpd during the closure, a second Hormuz blockade triggered by failed US-Iran nuclear talks would be economically devastating. Saudi Arabia is monitoring the talks closely — the PIF has already pivoted its 2026-2030 strategy to assume continuing Red Sea corridor reliance, but an irreversible Hormuz normalization is essential for full Eastern Province production recovery. Saudi oil exports via Ras Tanura on the Persian Gulf — historically the Kingdom's primary export terminal — remain dependent on Hormuz passage. The fragility of the ceasefire means Saudi Arabia's oil revenue recovery timeline remains deeply uncertain.
