The article examines recent developments in the global market for crude oil futures contracts. Amid persistently high trading volume of futures contracts for Brent and WTI global oil benchmarks structure of the market has recently changed profoundly. Share of non-commercial investors who are not directly linked to physical oil operations and are often considered speculators in the trade turnover of futures contracts for WTI at the NYMEX exchange has exceeded 50%. Financial investors play a prominent role in price discovery process for crude oil. However, world leading commercial banks that used to be the major participants in crude oil futures market and were also actively engaged into physical oil trading operations presently are forced to adjust their strategies responding to the regulatory reforms unleashed in the USA and European Union after the global financial crisis of 2008/2009. Provisions of Dodd-Frank Act in the USA and similar regulations in the European Union member countries aim to limit banks’ involvement in commodity derivatives market exclusively to hedging activities referred to swap transactions between banks and their clients. New tighter regulation substantially increases costs of commodity derivatives’ business for commercial banks. Also, the current US legislation prohibits banks from proprietary trading with derivatives instruments. These legislative innovations could substantially reduce banks’ profits. The largest global commercial banks have already reduced their physical commodity trading activities. The author concludes that while it is still unclear how significant the retreat of banks from crude oil derivatives market will be, the established mechanism of oil price setting is unlikely to change dramatically as new players from the financial sector are entering the market, replacing commercial banks.
