Oil Prices Plunge Over 4% on Iran Deal, Bakken Differential Widens

Oil prices tumbled sharply in Tuesday trading, extending losses triggered by a significant geopolitical development. West Texas Intermediate (WTI) crude was trading at $75.92 per barrel, down $3.52 or 4.43 percent, according to live price data. The international Brent crude benchmark fell to $79.49, down $3.68 or 4.42 percent.

The steep decline follows news of a diplomatic breakthrough that has eased supply disruption fears. According to a Rigzone report published Monday, crude prices extended a slide after the U.S. and Iran agreed to an interim deal aimed at reopening the Strait of Hormuz, a critical global oil transit chokepoint.

For Bakken producers, the price drop is compounded by a widening regional discount. The Bakken differential to WTI was recorded at -$3.42 per barrel, meaning Bakken crude is priced at a significant discount to the U.S. benchmark. The combined effect of lower benchmark prices and a wide differential puts additional pressure on wellhead economics for operators in the North Dakota formation.

In contrast to the crude sell-off, natural gas prices showed strength. The commodity was trading at $3.26 per million British thermal units (MMBtu), gaining $0.11 on the day. This aligns with updated government forecasts. In its latest Short-Term Energy Outlook released Tuesday, the U.S. Energy Information Administration raised its Henry Hub spot price forecasts for both 2026 and 2027, Rigzone reported.

The divergent price action highlights the different market forces at play. The sharp drop in oil is primarily driven by a reduction in the geopolitical risk premium, as the U.S.-Iran accord reduces the immediate threat to Middle Eastern supply routes. Meanwhile, natural gas is finding support from fundamental supply-demand expectations, as reflected in the elevated EIA price outlook.

For Bakken operators, today's price action underscores the sensitivity of the region's economics to global events. The significant price decline, if sustained, could impact cash flows and drilling budgets. The widening differential also reflects local market dynamics, including pipeline capacity and refinery demand, which can further erode the netback price received for Bakken barrels.
