Oil is a hot topic on the City's trading floors right now. Having peaked at $147/barrel just over a year ago, the price of crude oil dipped below $40/barrel only six months later. And now, having made a determined ascent for most of 2009, prices are still on the up. At the time of writing, oil has passed the $70/barrel level. So, what's the future for this volatile commodity? And how can you profit from these fluctuations in the price of oil? Well, there are some good arguments for taking a long view on the price of crude. While the world economy has been mired in the worst downturn in decades, production of commodities has been reduced in line with lower demand. This is particularly true of crude oil; as a price-stabilising measure, OPEC, the influential oil cartel, had cut production by 4.2 million barrels per day by the end of last year. As and when the economy recovers and gains momentum in the short-term, demand may once again begin to outstrip supply and cause prices to rise. In the longer term, growth in China and India will also increase demand for commodities, driving up prices. On the other hand, the global downturn was more than a blip and many economists predict that the shockwaves will be felt for a while to come. Rather than buying oil, those who subscribe to this more pessimistic view may see the recent gains in the price of crude as a good platform from which to short the commodity. Spread betting on oil can provide the ideal opportunity for those hoping to capitalise from a falling market, as financial spread betting offers down as well as up bets.
