The results of our cointegration analysis provide some moderate evidence that biofuel production has increased the link between food prices and oil prices. Generally, the most complex price links with crude oil are found for those foods that are used for biofuel production, but not exclusively so. Some more complex price relationships (asymmetries and complex causalities) are also found for a price relationship between crude oil and an agricultural product that is neither edible nor used for biofuel production (coffee), but most of these complex price relationships are found for the typical biofuel foods (sugar, soybean, sunflower, palm oil). Given that no cointegration relationship with crude oil prices could be identified for one of the most prominent biofuel foods (corn), the results are not entirely coherent and unanimous. This leads us to conclude that our analysis provides some indications of biofuel production providing an additional link between food and oil prices, but the evidence is not entirely coherent and clear. More research, particularly following our approach to analyze price links with crude oil for different food products (with different theoretical price transmission channels and biofuel impacts), may be necessary to draw clear-cut conclusions.
