Oil Prices Swing Wildly as OPEC+ Output Decision and Iran Sanctions Collide

Brent crude futures fell approximately 1 percent on May 7 to close at $100.06 per barrel, while WTI settled at $94.81, after swinging as much as 5 percent lower intraday on expectations of a US-Iran deal before recovering when a senior Iranian official appeared to rebuff the US proposal, CNBC reported. The UAE officially withdrew from the OPEC+ alliance on May 1, and OPEC+ announced on May 3 a production increase of 188,000 barrels per day for June, though analysts noted the increase faces shipping disruptions in the Strait of Hormuz. Reuters reported the proposed US deal would lift Hormuz restrictions in exchange for an Iranian moratorium on nuclear enrichment and US sanctions relief, but Iran's Mohsen Rezaei said Washington must pay reparations for damage done to Iran.

Analysis
Neither OPEC+'s accelerating output expansion nor renewed U.S. sanctions pressure on Iranian barrels has established a dominant price signal, and volatility is likely to persist through at least the next thirty days. Tehran has not formally responded to the current deal proposal, and OPEC+ quota compliance remains uncertain. Iranian supply is the more volatile instrument: sanctions enforcement can move several hundred thousand barrels per day on a compressed timeline, whereas OPEC+ production increases are gradual and partially priced in. That asymmetry explains the market's failure to establish directional conviction. Corroborated across Reuters and CNBC, the full magnitude of observed swings may instead reflect speculative and algorithmic positioning against Iran headline risk rather than any genuine reassessment of physical supply balances.
