McNally explicitly advises fading market speculation on a near-term US-Iran ceasefire and cites US force posture movements, including Marine units and 82nd Airborne, indicating escalation. Escalation in US-Iran conflict, potentially involving ground operations or a maritime quarantine, could disrupt Iran's oil exports, which are a significant component of global oil supply. Oil markets should monitor the situation closely as escalation poses upside risk to prices; direction is WATCH due to uncertain timing and specific form of military actions. US may not proceed with ground operations or escalation could be mitigated by diplomatic efforts, leading to a ceasefire that negates supply risks.
