Russia's oil trade is suffering from sanctions: an important trading partner is switching to the USA. If India were to buy more oil from the USA soon, Russia would have to look for other oil buyers.
Meanwhile, the USA appears to be benefiting from the sanctions against Russia. U.S. oil exports have set five new monthly records since 2022. It's not just the economic sanctions that will pose long-term challenges for Putin in the oil business. Ukrainian drone attacks have recently increasingly targeted large Russian oil processing camps.
