Oil prices experienced a significant surge of nearly 5% on Thursday, driven by fresh U.S. sanctions targeting major Russian energy companies Rosneft and Lukoil in response to the ongoing Ukraine conflict. Brent crude futures climbed by $2.98, or 4.8%, reaching $65.57 per barrel, while U.S. West Texas Intermediate (WTI) crude futures rose by $3.01, or 5.2%, to $61.51 per barrel. The sanctions, which extend measures previously imposed by Britain and the European Union, aim to pressure Moscow into agreeing to a ceasefire in Ukraine. The U.S. has warned of further actions if Russia fails to comply. The sanctions have forced major buyers of Russian oil, such as China and India, to reconsider their supply chains to avoid exclusion from the Western financial system. Indian refiners, including Reliance Industries, are reportedly planning to sharply reduce or halt imports of Russian crude. However, market analysts remain skeptical about the long-term impact of these sanctions, given Russia’s resilience in maintaining oil production and revenues despite previous measures. Oversupply concerns, fueled by OPEC+ production increases, have also tempered crude price gains. Meanwhile, U.S. demand for crude oil, gasoline, and distillates has strengthened, leading to a decline in inventories and supporting market sentiment.
