Rosneft and India's Indian Oil Corp have agreed to give up European Brent as a benchmark for Russian oil deals and switch to Asian Dubai, sources told Reuters. Benchmark Dubai, like Brent, is an oil benchmark that is priced in dollars by S&P Platts, a unit of S&P Global Inc, based in the United States. However, Dubai is focused on Asia and depends on trade in that region, while Brent is mostly used by major oil companies and traders in Europe.
