Global Oil Market Shifts Toward Contango as Iranian Barrels Re-Enter and Demand Concerns Surface
Theater: Global
Time horizon: 7d

Moderate confidence (60%)
Risk direction: volatile · Impact: CRITICAL
Executive summary
Over the coming seven days, the forward curve for Brent and WTI is likely to flatten or tilt modestly into contango as markets price in the prospect of increased Iranian exports against the backdrop of critically low stocks and high spot prices. Traders will anticipate gradual additional supply of 0.5–1.0 million barrels per day over subsequent months if waivers materialize, even as Ukrainian and Gulf risks keep nearby prices supported. Demand concerns tied to weak Chinese data will further temper the recent spike. Storage economics will improve, and time spreads will narrow.
