Speaker reports the Strait of Hormuz is largely blocked, trapping oil in the Persian Gulf and causing supply disruption, with Brent prices at $105 but recently moderating to around $100. The closure creates a significant supply shortage; prolonged closure increases operational challenges for restarting fields and refineries, sustaining supply constraints that should support higher prices. WATCH due to potential for price volatility and upside if geopolitical tensions and closure persist, but current moderation and US jawboning introduce near-term uncertainty. Successful US-Iran negotiations could lead to a ceasefire and reopening of the Strait, quickly alleviating supply pressure and capping price gains.
