Source: Valero Energy Corporation Presentation [Based on data from Valero, EIA, IEA] Demand for petroleum products is expected to be fairly strong over the next two years and beyond. Declines from developed markets in the OECD [excluding the United States, where petroleum demand is growing] are expected to be marginal this year while demand from non-OECD markets, which are generally emerging to developing, is forecasted to keep growing. Low oil prices is aiding growth, which in part prompted the IEA to recently raise its forecast for petroleum demand growth in 2015 by 280,000 bpd to 1.4 million bo/d. Strong demand is what's underpinning current prices, as supply remains very strong as well.
