In the period from 1970s to 1990s considerable amount of investment was made in the Oil Refinery Industry. But because of the oil shocks of 1973-74 and 1979-80 and because of the Asian Financial Crisis, the market demand was quite low. This resulted in surplus refining capacity of global Oil Refinery Industry.
But, the present scenario is different. As the Demand for Refined Petroleum and other Refined Products is increasing, Surplus Refining Capacity of the industry is diminishing very fast. So, in todays world, the Oil Refinery Industry has to concentrate on additional capacity building so that the Growing Market Demand can be met accordingly.
This additional capacity building naturally requires Heavy Investment. This is where the problem lies as the much needed investment in the Oil Refinery Industry is not attaining its required level because of the uncertainty of the investment returns. This is because, returns to the investment in Oil Refinery Industry were very low in the past three decades. But, the good news is that in the recent years the rates of return are improving. At present, the average margin per barrel has reached a level which is enough to cover the Capital Cost.
