Saudi Arabia will announce a unilateral crude production cut beyond its existing OPEC+ quota within 30 days

NEXUS forecast made 2026-09-18 at 28% probability. Pending, resolves by 2026-10-18.

Bayesian OPEC+ Production Decision analysis shows a narrow, fragile 38% bargaining range with most-likely equilibrium 'Saudi cuts production; US releases SPR' (fragile stability, coalition stability only 30%), suggesting Saudi unilateral action beyond quota is a live tail risk distinct from a standard OPEC+ ministerial announcement.
