Oil prices wide fluctuations have been a constant in energy economics, influencing heavily the profits of oil companies. Even small oil prices changes imply wide variations in the refining margins, the main economic drivers of the profits of oil companies with relevant refining assets. The future will bring an even more volatile environment as the level of implementation of low-carbon policies increases, implying a declining demand for refined products for internal combustion engine vehicles. One of the possible paths to mitigate the refining margin volatility and the decreasing demand for refined products is to switch gasoline production to aromatics products, through new aromatics plants. In this paper we apply the copula-GARCH model with Monte Carlo simulation to evaluate the economic impacts of this production switching, supporting a European oil company's decision. The results show that the product switch success depends on gasoline prices and on how the aromatics plant is built, if in stand-alone mode or integrated with the refinery. It is also shown that the desired reduction of the integrated refining margin volatility is not achieved with the product switching.
