Oil Prices Plunge 20% From 2026 Peak as US-Iran Ceasefire Hopes Drive Worst Monthly Drop Since COVID

BLUFMarket pricing reflects diplomatic hope rather than physical conditions, and inventory depletion near historic lows leaves oil exposed to a sharp spike if Strait constraints persist into June.

US officials told NBC News and CNBC Thursday that negotiators had completed a 60-day MOU to extend the ceasefire, pending Trump's approval 12. Trump on Friday stated he was about to make a "final determination" and listed conditions Tehran has previously rejected, including unrestricted Strait transit, mine removal, and US access to Iran's enriched uranium stockpiles 1. UBS reported May Iran crude loadings at below 0.3 million barrels per day against April's 1.5 million bpd average, while Iranian forces fired ballistic missiles at Kuwait and attack drones toward the Strait on Thursday 3. Exxon's Neil Chapman warned Thursday that inventories are approaching "unheard-of" lows and prices could spike above $150 per barrel if Strait constraints persist into June 2.

Analysis
Trump's stated conditions for Strait normalization, including unrestricted passage, mine removal, and US access to enriched uranium stockpiles, map to previously rejected demands, with MOU reporting resting on a single US official source and no Iranian-side confirmation. Iranian ballistic missile strikes against Kuwait and drone attacks toward the Strait Thursday confirm that operational violence is not tracking diplomatic momentum. Strait restoration to fully unrestricted commercial transit within 60 days is unlikely. Moderate confidence rests on May Iranian crude loadings of 0.3 million barrels per day against April's 1.5 million baseline. A spike toward or above $150 per barrel is the operative risk for June and July. The conditions may be domestic posture rather than binding requirements, with the MOU's "mostly agreed" status then signaling a narrower gap than stated conflicts imply. Energy procurement and reserve managers must treat June and July as the governing window absent Strait normalization.
