Phillips 66 Reports $900M Loss on Oil Hedges After Iran Conflict

What happened

Phillips 66 estimated approximately $900 million in pre-tax mark-to-market losses for the first quarter of 2026 due to its net short position in oil-related derivative contracts. The losses stem from the company's economic hedges on crude oil, refined petroleum products, natural gas liquids, and renewables feedstocks. These hedging positions moved against Phillips 66 as energy prices climbed sharply after the US-Israeli conflict with Iran began in late February. Iran's closure of the Strait of Hormuz, a critical waterway carrying roughly a fifth of global oil and gas supplies, disrupted energy markets and sent crude prices soaring. US benchmark crude surged nearly 68% since the conflict began, while diesel futures climbed 62%. The company held a net short position of approximately 50 million barrels in crude and products-related derivative contracts as of last month.

Why the stock moved

The stock likely reacted to the substantial financial impact disclosed by Phillips 66 following the Iran conflict. While the company faces $900 million in derivative losses, these paper losses on financial hedges could be partially offset by gains on the physical crude oil and fuels the refiner holds in inventory, which increased in value as prices surged. The refining segment is expected to absorb the largest share of mark-to-market losses at $350 million to $450 million, while marketing and specialties face $300 million to $400 million in impacts. Additionally, Phillips 66 experienced approximately $3 billion in cash outflows for collateral requirements on its derivative positions due to the commodity price run-up. In response, the company drew a new $2.25 billion 364-day term loan and increased another securitization facility from $1.25 billion to $1.75 billion to maintain liquidity.

Bigger picture

The situation highlights how refiners use derivative contracts to hedge price risk but can face substantial mark-to-market swings during extreme market volatility. Phillips 66's preliminary Q1 2026 results show the broader operational impacts beyond hedging losses. The refining segment is projected to post a loss of $200 million to $400 million, while renewable fuels could lose $50 million to $150 million. However, the midstream segment is expected to generate $550 million to $600 million in pre-tax income. The company also revised its global olefins and polyolefins utilization guidance downward to the low-90% range from the prior mid-90% estimate, partly due to reduced operations at CPChem's Middle East joint ventures. Despite the quarterly challenges, Phillips 66 maintained approximately $6 billion in liquidity as of March 31, 2026, consisting of $5 billion in cash and cash equivalents and $1 billion in committed credit capacity.

What investors watch

Investors will monitor Phillips 66's full first-quarter earnings report due later this month for complete financial details and management commentary on the geopolitical situation. Key areas of focus include whether the physical inventory gains actually offset the derivative losses as anticipated, and how sustained the impact from the Strait of Hormuz closure proves to be. The company's ability to manage collateral requirements and maintain operational flexibility during the energy price volatility will be important. Investors should also watch for updates on refining margins, utilization rates across segments, and any strategic adjustments to hedging practices. For context, Phillips 66 reported strong Q4 2025 results with net income of $2.9 billion compared to just $8 million in the prior-year quarter, so this setback comes after a period of solid performance.
